How to change a label in another exe

Hiya'll

How can I change a label in another program?

I've tried WM_SETTEXT but I couldn't get it to change the label?

If anyone knows how to do that please respond:D

Thanks

as far as I know, they can't be changed because they don't have a window handle. Windows draws them directly without using the Edit class to help save resources.

Are you talking about a VB-created application? C++? or Delphi?

I think it's either a VB-created application or c++, not delphi:)

Ok.....

Can maybe then someone tell me how to READ the caption/text of another program? I know for sure this can be done
but I just don't know how :p

Thanks:D

The debate is not whether you can read or write, rather it's whether it's a C++ or a VB app.

If it's a C++ App, then you could use this.

Code:

---

hwndParent = FindWindowEx(0, 0, "ClassName", "WindowName")
hwndLabel = FindWindowEx(hwndParent, 0, "Static", "Text of label")
SendMessage hwndLabel, WM_SETTEXT, 0, ByVal "My new Text"

---

If it's a VB App, then you can't do it, because as Chrisjk explained, they are drawn on to the parent's DC.

thanks megatron:D
