Rich Edit Question

[Gösta H. Lovgren-2]

I'll hve a dig around the forums tomorrow and see if I can find how to do this.

Cheers!

Maybe I can save you a little time, Steve. The function "Clipboard_Get_Text" (below) will just return straight text, which you can retrieve and plug into your control. Or just use the Macro.

'<== Start of Clipboard as an Include ==>
'Clipboard stuff gotten from Poffs but I forget from whom
'
'Note t$ must be initialized - Local t$
 
Function Clipboard_Set_Text Alias "Clipboard_Set_Text" _
(ByVal sText As String) Export As Long
Local hData As Long, hGlob As Long
 
' ** Create a global memory object and copy the data into it
hData = GlobalAlloc(%GMEM_MOVEABLE Or %GMEM_DDESHARE, Len(sText) + 1)
hGlob = GlobalLock(hData)
Poke$ hGlob, sText + Chr$(0)
GlobalUnlock hData
 
' ** Open the clipboard
If IsFalse(OpenClipboard(%Null)) Then
GlobalFree hData
Exit Function
End If
 
' ** Paste the data into the clipboard
EmptyClipboard 'WinAPI
Function = SetClipboardData(%CF_TEXT, hData) 'WinAPI
CloseClipboard 'WinAPI
End Function
 
Function Clipboard_Get_Text Alias "Clipboard_Get_Text"() Export As String
Local zPtr As Asciiz Ptr
OpenClipboard 0 'WinAPI
zPtr = GetClipboardData(%CF_TEXT)
If zPtr <> 0 Then Function = @zPtr
CloseClipboard 'WinAPI
End Function
' 
 
'
Macro Get_Clipboard = t$ = Clipboard_Get_Text 'put cb in tb at program start 
'
Macro Set_Clipboard = Clipboard_Set_Text(t$)
'
 
'<== End of Clipboard as an Include ==>

If you mean when the user is pasting text from the clipboard, you have to subclass the RichEdit control and intercept WM_PASTE - from there you can grab the clipboard data as plain text and use EM_REPLACESEL to insert it, then exit the subclass proc without allowing the control to ever receive WM_PASTE.

Ronald, sounds like a great solution but I have no idea how to do this!

Paste In Another Format

Assuming you mean cutting from web page and pasting into an MS richedit control:

1. Subclass the richedit control.
2. Monitor for the Ctrl+V paste command.
3. OpenClipboard.
4. Browsers (at least Firefox and IE) copy multiple clipboard formats, including a standard clipboard format %CF_TEXT. (You may want to check for another which better meets your needs.) Use IsClipboardFormatAvailable to verify clipboard has data in that format.
5. Retrieve your desired format with GetClipboardData into a memory block.
6. Insert the memory block at the richedit control's selection.
7. CloseClipboard, which will also free the memory block.

Hope this helps.

I'm using a richedit control for user input. When the user copies text from a web page, I need to discard all font/ colour formatting. Can this be done?
