How to get text from an EditorGadget()? The API way...

Hello!
I am creating a "peek" program just like WinPeek with that you can view and edit stuff of other windows. However, I stumbled in this situation that I don't know how to get text from an EditorGadget() (RichEdit20A).
I tried using GetWindowText_(), but it returns an empty string. But if I use GetWindowText_() with another control like a button, then it works.
So, it's not an issue with my code, but with the Win API.
Thanks

You can use the following to retrieve the text in one great 'lump'! This will include any control codes separating individual lines though.
Code: Select all
tlen = SendMessage_(GadgetID(#edit), #WM_GETTEXTLENGTH, 0, 0) + 1
edit$ = Space(tlen)
SendMessage_(GadgetID(#edit), #WM_GETTEXT, tlen, @edit$)
Why not GetGadgetText() though?

THanks srod!

If I retrieve a system handle to a control, I can't use PB commands with it, as PB commands need the #number of the gadget and not the #handle. Capich?

You may be interested in this api function :
CtrlID = GetDlgCtrlID_( GadgetID(100) )
Then CtrlID should be 100.

GetDlgCtrlID_(ehWnd) will return the PB identifier for the gadget with the window's handle ehWnd etc. This assumes of course that you created the rich edit control with PB commands.

does this mean if you have the handle, for example of the input gadget for the URL in let's say firefox, and you do ctrlid = GetDlgCtrlID_(handlehere) , would I be able to take the ctrlid result and use it in gadget functions?

Oh man! I am so dumb. Yesterday I was working on a project with Pelles C using dialogs. And I knew that there was this GetDlgCtrlID_() function..
Thanks! Now I am enjoying the affair between PB and API more and more!

In short, no! The control will mean nothing to PB as it will have no record of having created the control. In this case it is API all the way!

Mr. IKnowEverything (srod), why did you want to tell me then that there is the GetDlgCtrlID_() API function? If I can't use PB commands with the returned CtrlID, what's the use of it then?

Josku_x, not entire sure what just bit your backside there? My previous post was entered before I noticed your post.
Besides, did you even read my original post on the subject of GetDlgCtrlID_() ? Let me just repeat it for you:
GetDlgCtrlID_(ehWnd) will return the PB identifier for the gadget with the window's handle ehWnd etc. This assumes of course that you created the rich edit control with PB commands.
I guess you missed the 'assume...' part.

BTW: I can't get my code to work. I am using this code:
Code: Select all
SetClipboardText(GetGadgetText(GetDlgCtrlID_(hWnd)))
After I set the hWnd handle to the RichEdit (I get the handle through WinPeek) the program crashes and nothing happens.. Is it expected to be like this?

SetClipboardText(GetGadgetText(GetDlgCtrlID_(hWnd))) is 'assumed' to work only if hWnd comes from a StringGadget(), TextGadget(), EditorGadget(), etc...
