Highlighting text

Since there is no .SelHighlight property of the RichTextBox control, I created one.Code:

Public Sub HighLight(RTB As RichTextBox, lColor As Long)

'add new color to color table

'add tags \highlight# and \highlight0

'where # is new color number

Dim iPos As Long

Dim strRTF As String

Dim bkColor As Integer

With RTB

iPos = .SelStart

'bracket selection

.SelText = Chr(&H9D) & .SelText & Chr(&H81)

strRTF = RTB.TextRTF

'add new color

bkColor = AddColorToTable(strRTF, lColor)

'add highlighting

strRTF = Replace(strRTF, "\'9d", "\up1\highlight" & CStr(bkColor) & "")

strRTF = Replace(strRTF, "\'81", "\highlight0\up0 ")

.TextRTF = strRTF

.SelStart = iPos

End With

End Sub

Notice that in addition to inserting the \highlight tags I also insert \up# tags.

This is so that I can check to see if a selection is highlighted by querying the

.SelCharOffset function. This routine relies on the following function that adds

a new color to the RTF color tableCode:

Function AddColorToTable(strRTF As String, lColor As Long) As Integer

Dim iPos As Long, jpos As Long

Dim ctbl As String

Dim tagColors

Dim nColors As Integer

Dim tagNew As String

Dim i As Integer

Dim iLen As Integer

Dim split1 As String

Dim split2 As String

'make new color into tag

tagNew = "\red" & CStr(lColor And &HFF) & _

"\green" & CStr(Int(lColor / &H100) And &HFF) & _

"\blue" & CStr(Int(lColor / &H10000))

'find colortable

iPos = InStr(strRTF, "{\colortbl")

If iPos > 0 Then 'if table already exists

jpos = InStr(iPos, strRTF, ";}")

'color table

ctbl = Mid(strRTF, iPos + 12, jpos - iPos - 12)

'array of color tags

tagColors = Split(ctbl, ";")

nColors = UBound(tagColors) + 2

'see if our color already exists in table

For i = 0 To UBound(tagColors)

If tagColors(i) = tagNew Then

AddColorToTable = i + 1

Exit Function

Super and Subscripting

Two other functions that the RichTextBox control does not gives us are super and subscripting.

As before we can accomplish this by inserting RTF code. Notice again that I also add \up0

and \dn0 tags so that I can determine if text has been subscripted by querying the

.SelCharOffset property.




Code:

Public Sub SetSubScript(RTB As RichTextBox)

Dim iPos As Long


With RTB

If .SelCharOffset >= 0 Then

'subscript the current selection

iPos = .SelStart


strRTF = Replace(.TextRTF, "\'9d", "\sub\dn2 ")

.TextRTF = Replace(strRTF, "\'81", "\nosupersub\up0 ")

.SelStart = iPos

Else 'turn off subscripting

.SelText = Chr(&H9D) & .SelText

strRTF = .TextRTF

.TextRTF = Replace(strRTF, "\'9d", "\nosupersub\up0 ", , 1)

End If

End With

End Sub

Public Sub SetSuperScript(RTB As RichTextBox)

'add tags \super\up1 and \nosupersub\up0

Dim iPos As Long


With RTB

iPos = .SelStart

If RTB.SelCharOffset <= 0 Then

'superscript the current selection


strRTF = Replace(.TextRTF, "\'9d", "\super\up2 ")

.TextRTF = Replace(strRTF, "\'81", "\nosupersub\up0 ")

Else 'turn off

.SelText = Chr(&H9D) & .SelText

Insert Tables

Another useful functionality that can be added to the RichTextBox controls is the ability to insert tables.

The RichTextBox controls support a limited subset of the table related Rich Text Format tags, but none

of that is made accessible to users of the control. I've attached a class that you can use to insert tables

into your RichTextBox controls.

Properties - all sizes are in twips

xLeft - Position of the left edge of the table

isCentered - Set to True to center the table

Rows - Sets or returns the number of rows in the table

Columns - Sets or returns the number of columns in the table

Row - An Array of Rows (1 to Rows)

Column - An Array of columns (1 to Columns)

Column(i).xWidth - Width of the ith column

Cell - A 2-d Array of Cells (1 to Rows, 1 to Columns)

Cell(r, c).Contents - Sets or returns the contents of the cell

Methods

InsertTable(RTB As RichTextBox) - Inserts the table into the RichTextBox at the currrent cursor position.

An example of use isCode:



Option Explicit

Dim RTFtable As clsRTFtable

Private Declare Function LockWindowUpdate Lib "user32" ( _

ByVal hwndLock As Long _

) As Long

Private Sub Command1_Click()

Dim i As Integer

Set RTFtable = New clsRTFtable

'stop flicker

Call LockWindowUpdate(RichTextBox1.hWnd)

For i = 1 To 5

With RTFtable

'set the size of the table

.Columns = 3

.Rows = 2

'fill the cells

'Row 1

.Cell(1, 1).Contents = "Row 1"

.Cell(1, 2).Contents = "Column2"

.Cell(1, 3).Contents = "Column3"

'Row 2

.Cell(2, 1).Contents = "Row2"

.Cell(2, 2).Contents = "R2C2"

.Cell(2, 3).Contents = "R2C3"

'do we want to center it on the page?

.isCentered = True

'insert the table at the current cursor postion

Insert Pictures

There are several ways to insert pictures into a RichTextBox control.

This is one method that does not rely on the clipboard, but does use some

metafile stuff. Here is the routine to insert the pictureCode:

'Inserts the picture at the current insertion point

Public Function InsertPicture(RTB As RichTextBox, pic As StdPicture)

Dim strRTFall As String

Dim lStart As Long

With RTB


strRTFall = .TextRTF

strRTFall = Replace(strRTFall, "\'9d", PictureToRTF(pic))

.TextRTF = strRTFall

'position cursor past new insertion

lStart = .Find(Chr(&H81))

strRTFall = Replace(strRTFall, "\'81", "")

.TextRTF = strRTFall

.SelStart = lStart

End With

End Function

Here is the routine that converts the picture into an RTF stringCode:



'returns the RTF string representation of our picture

Public Function PictureToRTF(pic As StdPicture) As String

Dim hMetaDC As Long, hMeta As Long, hPicDC As Long, hOldBmp As Long

Dim Bmp As BITMAP, Sz As Size, Pt As POINTAPI

Dim sTempFile As String, screenDC As Long

Dim headerStr As String, retStr As String, byteStr As String

Dim ByteArr() As Byte, nBytes As Long

Dim fn As Long, i As Long, j As Long

sTempFile = App.Path & "\~pic" & ((Rnd * 1000000) + 1000000) \ 1 & ".tmp" 'some temprory file

If Dir(sTempFile) <> "" Then Kill sTempFile

'Create a metafile which is a collection of structures that store a

'picture in a device-independent format.

hMetaDC = CreateMetaFile(sTempFile)

'set size of Metafile window

SetMapMode hMetaDC, MM_ANISOTROPIC

SetWindowOrgEx hMetaDC, 0, 0, Pt

GetObject pic.Handle, Len(Bmp), Bmp

SetWindowExtEx hMetaDC, Bmp.Width, Bmp.Height, Sz

'save sate for later retrieval

SaveDC hMetaDC

'get DC compatible to screen

screenDC = GetDC(0)

hPicDC = CreateCompatibleDC(screenDC)

ReleaseDC 0, screenDC

'set out picture as new DC picture

hOldBmp = SelectObject(hPicDC, pic.Handle)

Find and Replace Common Dialog

Until recently I didn't know that you could access the "Find-And-Replace" Common Dialog.

Here is a class that makes it easy to access. The class will work with either a standard TextBox or a

RichTextBox.

Here is an example of how you might use the class.Code:

Option Explicit

'declare with events so that we can override the default

'behavior of the class and/or handle ShowHelp

Dim WithEvents FindDialog As clsFindandReplace

Private Sub Form_Load()

Set FindDialog = New clsFindandReplace

End Sub

Private Sub Command2_Click()

'show the Find and Replace dialog box

'pass the handle of our RichTextBox to

'the class

FindDialog.ShowReplace RTB.hwnd

End Sub

Full Featured Spell Checker

Here is a class that provides full spell checking functionality for the RichTextBox. This class has only two

methods:

GetSpellingErrors checks the spelling in all the text of a RTB and returns the number of spelling errors found

and marks then all. A right-click on any error brings up a popup menu with suggested changes. If the user

selects a change from the menu, then the replacement is made.

ClearSpelling clears all the marked errors.

Here is an example of use:Code:

Option Explicit

Private SpellCheck As clsSpellCheck

Private Sub cmdSpellCheck_Click()

SpellCheck.GetSpellingErrors RTB

End Sub

Private Sub cmdStopSpell_Click()

SpellCheck.ClearSpelling

End Sub

Private Sub Form_Load()

Set SpellCheck = New clsSpellCheck

RTB.LoadFile App.Path & "\recipe.rtf"

End Sub

This code also provides an example of several other things.

How to implement the EN_LINK notification function of the RichTextBox. This notification is usually used to

mark hyperlinks and respond to mouse events over them. I use it to mark spelling errors and to bring up a

popup menu of spelling suggestions for the user to select from.

I have included a class that is used to create and respond to popup menus. I put this functionality into a

class because I wanted all the spell checking functionality contained within a class with none of the code

in the form.

Also included is my "Cute Little Subclasser" class. I use this class whenever I want subclassing

capabilities. When this class is declared WithEvents, the user can write code to respond to Windows

messages within the form or class's own module. It also is a little more stable than doing your own

subclassing since it always remembers to turn itself off.

Attached is the source code for all the above mentioned items PLUS a free mispelled recipe!Attached Files

Get row and column number of cursor

Here is some simple code that will give you the cursor position in a RichTextBox, It gives you the line number and

the column number of the cursor. Attached is a project that demonstrates use of the routine.Code:



Option Explicit

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" ( _

ByVal hwnd As Long, _

ByVal wMsg As Long, _

ByVal wParam As Long, _

lParam As Any _

) As Long

Private Const EM_GETLINECOUNT = &HBA

Private Const EM_LINEINDEX = &HBB

Private Sub GetCursorPos(RTB As RichTextBox, iLine As Integer, iPos As Integer)

Dim lCount As Long

Dim i As Long

Dim LN As Long

lCount = SendMessage(RTB.hwnd, EM_GETLINECOUNT, 0&, 0&)

LN = SendMessage(RTB.hwnd, EM_LINEINDEX, -1&, 0&)

For i = 1 To lCount

If LN = SendMessage(RTB.hwnd, EM_LINEINDEX, i - 1, 0) Then Exit For

Next i

iLine = i

iPos = RTB.SelStart - LN + 1

End Sub

Auto Detect and respond to URLs

The RichTextBox control has the ability to detect URLs as they are typed. It can convert this text into a

hyperlink which can launch a browser when clicked.

To turn on Auto URL detection simply send the RTB an EM_AUTOURLDETECT message.

When the control detects that a URL is being entered, it reformats the text being entered so that it looks like a

hyperlink and marks that text with a CFE_LINK effect.

When the mouse pointer is over text with a CFE_LINK effect, the RTB can be configured to send a message to

its parent. In order to respond to mouse events over the hyperlink text, the parent has to be subclassed or

hooked.

The following code shows how to setup Auto URL detectionCode:

Public Sub EnableAutoURLDetection(RTB As RichTextBox)

'enable auto URL detection

SendMessage RTB.hwnd, EM_AUTOURLDETECT, 1&, ByVal 0&

'subclass the parent of the RTB to receive EN_LINK notifications

Set FormSubClass = New clsSubClass

FormSubClass.Enable RTB.Parent.hwnd

'set RTB to notify parent when user has clicked hyperlink

SendMessage RTB.hwnd, EM_SETEVENTMASK, 0&, ByVal ENM_LINK

End Sub

And to respond to a left mouse click you could do the following in your form's subclass routine.Code:



Private Sub FormSubClass_WMArrival(hwnd As Long, uMsg As Long, wParam As Long, lParam As Long, lRetVal

Dim notifyCode As nmhdr

Dim LinkData As ENLINK

Dim URL As String

Select Case uMsg

Case WM_NOTIFY

CopyMemory notifyCode, ByVal lParam, LenB(notifyCode)

If notifyCode.code = EN_LINK Then

'A RTB sends EN_LINK notifications when it receives certain mouse messages

'while the mouse pointer is over text that has the CFE_LINK effect:

'To receive EN_LINK notifications, specify the ENM_LINK flag in the mask

'sent with the EM_SETEVENTMASK message.

'If you send the EM_AUTOURLDETECT message to enable automatic URL detection,

'the RTB automatically sets the CFE_LINK effect for modified text that it

'identifies as a URL.

CopyMemory LinkData, ByVal lParam, Len(LinkData)

If LinkData.Msg = WM_LBUTTONUP Then

'user clicked on a hyperlink

'get text with CFE_LINK effect that caused message to be sent

URL = Mid(RTB.Text, LinkData.chrg.cpMin + 1, LinkData.chrg.cpMax - LinkData.chrg.cpMin)

'launch the browser here

ShellExecute 0&, "OPEN", URL, vbNullString, "C:\", SW_SHOWNORMAL

End If

End If

lRetVal = FormSubClass.callWindProc(hwnd, uMsg, wParam, lParam)

Attached is a project that demonstrates the whole idea.Attached Files

Re: RichTextBox Tricks and Tips

Wow, you have some really great stuff here!

But I see one major draw back.

In SpellCheck.zip you have a dll named DBGWPROC.DLL.

Its properties say:

You have a license to use this file only if you have a copy of the book. You may not redistribute this file.

The DbgWProc.Dll is only used for debugging purposes so doesn't really need to be included, but the author (

Matthew Curland) has given his permission to redistribute it. The file is freely available many places around the

iternet.

Hi:

First off, thanks so much for posting the codes for inserting tables. That's much appreciated!!!



I have access to the control characters for rft documents and what I'd like to do is to have codes that would

allow user to change the boarder of the cell that the user's cursor is in (inside a rich text box).

I have searched the net high and low for info. on how to programatically select all the control characters that is

associated with that cell and then make modification to them (e.g.: flagging \ckbrdk to false).

Could you kindly help me out with this? I would really appreciate it!

Thank you in advance!

Re: Insert Tables

Hi,

very nice codes...

I found one bug in RTFtable

VB Code:

1. Public Sub InsertTable(RTB As RichTextBox)

2. 'set column widths

3. For c = 1 To mvarColumns

4. strInsert = strInsert & "\cellx"

5. w = mvarxLeft

6. For i = 1 To c

7. [color=Red]w = w + mvarclsColumn(c).xWidth[/color]

8. Next i

9. strInsert = strInsert & CStr(w)

10. Next c

If you have all columns same size you can't see difference, but

must be:

w = w + mvarclsColumn(i).xWidth

Hi All

I have strange problems with the syntax highlighting programming

No.1 Sendmessage is often out of work

'----------------------Quotation----------------------

LN = SendMessage(RTB.hwnd, EM_LINEINDEX, Byval LineNum, 0&)

'----------------------Quotation----------------------

this works fine in ANSI mode(english text),but when I use UNICODE mode,it returns wrong result as always. I have

to seek the preview enter key to locate the fst pos of a line.

No.2

'----------------------Quotation----------------------

.SelStart



.SelLength

.SelColor

'----------------------Quotation----------------------

if selected Line number is under 200,this goes fast,but when it's above 1000,it just stuck over there with a delay

of 1 second or more,within these time,the keyboard action might be all in a mess.

can you give me some suggestion? thx a lot

Maybe I am confused but I am trying to highlight text on the go without changing the cursor position. Is there

anyway to get the RTF text position? Selstart only has it for the standard text and I need the rtf selstart so that

I can insert my own colour tags before and after my word.

Just in case your wondering I am writing a script editor and the cursor jumps the box around whenever I highlight

words

Probably the easiest thing to do is lock the window while you are doing the highlighting with LockWindowUpdate.

VB Code:

1. Private Declare Function LockWindowUpdate Lib "user32" ( _

2. ByVal hwndLock As Long) As Long

3.

4. Private Sub Command1_Click()

5. Dim iPos As Integer

6. 'save the current cursor position

7. iPos = RTB.SelStart

8. 'prevent the window from changing

9. LockWindowUpdate RTB.hWnd

10. 'highlight a word

11. RTB.Find "is"

12. HighLight RTB, vbYellow

13. 'restore the cursor position

14. RTB.SelStart = iPos

15. 'unlock the window

16. LockWindowUpdate 0

17. End Sub

When I try to set the xwidth to 3.5 it dosen't not draw a table, the text is all scambled.

I need the width of each cell to be 3.5inch

I need the Height of each cell to be 2inch

I need there to be 2 columns, with 5 rows.

What is the best way to accomplish this?

EDIT:

I got the width correct, I was using 3.5, when I should have been using Twips, 5040.

How do I do the Height of each cell to be exactly 2inches? Or 2880 Twips.

that looks like this (from which I will strip away the URL tags)

All you need to do is mark the text that you want to attach a hyperlink to with the CFE_LINK Effect. You'll have

to keep the URL in a list somewhere so you can respond to user mouse clicks in your WM_NOTIFY event

interception.

See my cool spell checker example for how to do this. The spell checker marks all mispelled words with the

CFE_LINK effect so that when the user right clicks on it spelling suggestions can be made.

BTW this is much better than RobDogg's simple little spell checker

Edit: the link you provided above does not work.

I just downloaded the clsSpellCheck example and I ran into a problem. When I run it I see the recipe (which I've made

previously BTW ). I click Spell Check and it underlines all the misspellings. However when I double-clicked one of them

nothing happened, so I clicked Spell Check again and got an Invalid property value error in this line

VB Code:

1. 'find each misspelling in the document

2. For Each spError In WordDoc.SpellingErrors

3. iPos = mRTB.Find(spError, iPos + 1, , rtfWholeWord Or rtfMatchCase)

4. [hl="#FFFF80"]mRTB.SelStart = iPos[/hl]

Okay I have the word "this" in my example above formatted with the CFE_LINK effect and I have the associated

URL stored in a collection and the richtextbox is enabled for AutoURLDetection. How do I actually get the RTB to

open the browser to the stored URL? I assume I have to do something in the RTB's Click event, but what?

I was able to hammer out a way to do it but I'd still be interested in the right way.

The spell checker requires that you right click on a word not double click.

To respond to the user clicking on your hyperlink, see the AutoURL example above.

when text in an RTB has its CFE_LINK effect set, the text will be blue and underlined. More importantly, the RTB

will send a WM_NOTIFY message to its parent form for certain mouse operations on the text.

To respond to these messages (such as a left click) you have to subclass the parent form and intercept these

messages.

So,

1. see the spell check example to see how to set the CFE_LINK effect for text.

2. See the AutoURLDetect example to see how to bring up the browser (or whatever action) when the user clicks

on your special text.

And I did receive your email and even responded.

Thanks, I've done all that and I basically have it working. I do have a problem though. Take a look at my post

#28. You see that I'm substituting the "Script prompt" that you optionally enter when you insert a hyperlink in a

post for the URL itself, so when the user clicks on the underline-blue word I need to tell VB somehow what the

URL associated with that word is. I've worked that out by storing both pieces of data in a modified version of your




MisSpellings collection and I can now get the browser to open to the correct page. My problem is however, what

to do about situations where the same underlined-blue word occurs in more that one place? In that situation

there would likely be different URLs associated with them, so what I'd like to do is store some unique, identifying,

rtf tag before or after the underlined-blue word where that tag would be the index to the proper entry in the

collection. Can I insert things like \'123 into the rtf?

I never received your response to my emails so if you could send me a PM with what you said I'd appreciate it.

Ok I understand your question now. I thought it was strange that I was having to explain things to you that are

spelled out in the example.

Here is an idea:

What if there were two URLs and I needed to be able to differentiate them?

My idea is to insert your URL right in the RTF text and hide it with the \v tags.

You can then retrieve this info when the user clicks the adjacent hyperlink.

Does this not work?

No, that seems like a great idea! I had no idea (until now) what the \v tag did. Is there a comprehesiuve list

someplace of rtf tags?

Here is the specification of RTF 1.5

http://www.biblioscape.com/rtf15_spec.htm

Note however that the richtextbox control supports only about 10% of the codes.

I use the vbforums editor to test codes.

Go to View\RTF

Then enter the codes you want to test

Then select View\Normal to see if it worked.

If it didn't work and you go back to View/RTF and the code you entered is gone, then the control does not

support it so it removed it.
