Code updated for 5.20+

Restored from previous forum. Originally posted by Justin.

This code uses a window callback to monitor the clipboard for a change, if it is a text change it will display it.

Code: Select all

Procedure CBCallback(hwnd,msg,wParam,lParam)
  Shared hwndNextViewer
  ReturnValue=#PB_ProcessPureBasicEvents
  
  Select msg
    Case #WM_CHANGECBCHAIN
      ;If the next window is closing, repair the chain
      If hwnd = hwndNextViewer 
        hwndNextViewer = hwnd
        ;Otherwise, pass the message to the next link
      Else
        If hwndNextViewer<>#Null 
          SendMessage_(hwndNextViewer,msg,wParam,lParam)
        EndIf 
      EndIf

      cbtxt$=GetClipboardText() ;text only

hwnd=OpenWindow(0,200,200,300,100,"Monitoring Clipboard",#PB_Window_SystemMenu|#PB_Window_MinimizeGadget)

hwndNextViewer=SetClipboardViewer_(hwnd)
SetWindowCallback(@CBCallback())

Repeat 
Until WaitWindowEvent()=#PB_Event_CloseWindow 

;remove the pb window from the chain of clipboard viewers

Is there any way to get both the Rich Text from the clipboard AND the plain
text together, perhaps into two variables? I'd like to be able to get both at
the same time, but it seems I can only get plain text...

This should do the trick:

Code: Select all

.
.
CF_RTF.l = RegisterClipboardFormat_("Rich Text Format")
.
.
.
rtfData = GetClipboardData_(CF_RTF) ; get RTF data
.
.
txtData = GetClipboardData_(#CF_TEXT) ; get plain text
.
.
.

PB, did it work as expected?

Posted: **Wed Apr 06, 2005 12:20 am**

I haven't had a chance to test it yet... I'm hoping to get some time later
tonight (it's 9:20am here and I don't finish work till 5:30pm).

Background of my question: I want to search/replace certain text in the
clipboard, but my problem is how to know whether the format in the
clipboard is Rich Text or Plain Text. Because if I get the text and then
use ReplaceString on it, and then use SetClipboardText, then it'll destroy
any Rich Text formatting that's there (or will it?).

So basically, I need to do search/replace on the clipboard but set the new
clipboard with the original text format, which I'm not sure how to do. But
with your tip, hopefully I'll work it out.

Does all this make sense? I just read it and got confused.

Me too

Let's see how you progress, maybe things are clearer then

> Let's see how you progress, maybe things are clearer then

Not much clearer, I'm afraid.

Okay, it's like this: When you copy text in Microsoft Word, it's stored in the
clipboard as rich text. That is, when you paste that clipboard into another
Word document, it keeps the font, color, style, size, etc.

Now, if I use the PureBasic GetClipboardText command, it only gets the
plain text, and strips out the font, color, style, size. What I want to do is
get the clipboard text, do a search/replace on it, then copy it back to the
clipboard. But, as I said, if I do this then it loses the font, color, etc, and
the clipboard now holds just a plain text version of the replaced text.
So, if I copy a red bold phrase from Word, do the search/replace, then
paste it back, it gets pasted back as a black plain phrase, instead of red
bold with the changes. I wanted to retain that formatting, but I can't find
a way to do it.

Get your RTF Text like I wrote in my previous post and after replacing use
SetClipboardData() instead of SetClipboardText(). This way the formatting
remains.

Code: Select all

rtfData.l = GetClipboardData(CF_RTF)
replaced.s = ReplaceString(PeekS(rtfData), "PureBasic", "PUREBASIC", 1)
SetClipboardData(CF_RTF, replaced)

I tried it, it works.

Thanks traumatic -- I was trying to resave it with SetClipboardText instead
of SetClipboardData!

Thanks for your help on this; it's very appreciated.

You're welcome! I'm glad it works now.

I needed to do this today (search and replace RTF text in the clipboard) but per my post at http://www.purebasic.fr/english/viewtop ... 3&p=480142 you'll see that the Get/SetClipboardData() commands no longer exist.

Can someone please post a workaround if they know how?

Below is what I've tried (in Unicode), which doesn't work. The answer may be here: https://support.microsoft.com/en-us/kb/258513 but I don't quite follow it.

Code: Select all

; Assume that the word "PureBasic" is bold and red,
; so that replacing it will also be bold and red.

CF_RTF=RegisterClipboardFormat_("Rich Text Format")

If OpenClipboard_(0)

  c=GetClipboardData_(CF_RTF)

  cliprtf$=PeekS(@c)
  cliprtf$=ReplaceString(cliprtf$,"PureBasic","PUREBASIC")
  
  SetClipboardData_(CF_RTF,cliprtf$)
  
  CloseClipboard_()

EndIf

Hi

Code: Select all

; Assume that the word "PureBasic" is bold and red,
; so that replacing it will also be bold and red.

CF_RTF=RegisterClipboardFormat_("Rich Text Format")

If OpenClipboard_(0)
    cbHnd = GetClipboardData_(CF_RTF)
    txtLen = lstrlen_(cbHnd)*SizeOf(character)
    cliprtf$ = Space(txtLen)    
    CopyMemory_( cliprtf$, cbHnd, txtLen)
    cliprtf$ = PeekS(@cliprtf$,txtLen,#PB_UTF8)
    cliprtf$=ReplaceString(cliprtf$,"PureBasic","PUREBASIC")
    CloseClipboard_()
    Debug cliprtf$
EndIf

;Ascii or Unicode

Thanks Rashad: cliprtf$ does indeed hold the replaced text; but how do I put that back into the clipboard as rich text?

If I use SetClipboardText(cliprtf$), then pasting it in Word (and also WordPad and Gmail) removes all formatting and does it as plain text.

And using SetClipboardData_(CF_RTF,@cliprtf$) doesn't do it either, it just pastes the original text.

Basically, the goal is that I'm cutting rich text from Word with Ctrl+X, running your procedure, and pasting the replaced text back into Word again with Ctrl+V.

Hi Dude

Code: Select all

; Assume that the word "PureBasic" is bold and red,
; so that replacing it will also be bold and red.

CF_RTF=RegisterClipboardFormat_("Rich Text Format")

If OpenClipboard_(0)
    cbHnd = GetClipboardData_(CF_RTF)
    txtLen = lstrlen_(cbHnd)*SizeOf(character)
    cliprtf$ = Space(txtLen)   
    CopyMemory_( cliprtf$, cbHnd, txtLen)
    cliprtf$ = PeekS(@cliprtf$,txtLen,#PB_UTF8)
    cliprtf$=ReplaceString(cliprtf$,"PureBasic","PUREBASIC")
    mem = GlobalAlloc_(#GHND,lstrlen_(cliprtf$)*SizeOf(character)+1)
    lpstr = GlobalLock_(mem)
    PokeS(lpstr,cliprtf$,-1,#PB_UTF8)
    GlobalUnlock_(mem)
    EmptyClipboard_()
    SetClipboardData_(CF_RTF,mem)
    CloseClipboard_()   
    GlobalFree_(mem)
EndIf

  If OpenWindow(0, 0, 0, 322, 150, "EditorGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    EditorGadget(0, 8, 8, 306, 133)
    For a = 0 To 5
      AddGadgetItem(0, a, "Line "+Str(a))
    Next
    Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
  EndIf

; Now You can paste the revised text into the editor gadget using Ctrl-V
