Hey every one...
I have read and tested some stuff with "SetWindowText"
and when i use SetWindowText i can change the caption of my appelcation, but I think it is possible to change window's caption of other programs....

i am not sure if it is SetWindowText(hWnd,"My Text");

but i used it and it gave me an eroor... so any help?

thanks alot

Hi.
you can use
Findwindow(wndclass,wndtetxt) API function to retrive the
hwnd for any window, and then you can use
SetWindowText function.

.
if you need some help contact me on faroq_tam2004@yahoo

My telepathy powers are weak today. Can you tell us what the error is?

From where and how are you calling SetWindowText()?

I creat a button, and from the classwizard I chose BN_Clicked and I add function. then I click edit code and write SetWindowText(hWnd,"My Text");... so it will be

void CAdfadfhgDlg::OnButton1()
{
SetWindowText(hWnd,"My Text");
}

I think i am doing something wrong... right?

Right, you are doing something wrong. Simply remove the hWnd parameter. It's not needed since you are already in the context of the dialog. That will fix that particular compiler error.

Yeah I did that also, but this will change my applecation's Caption not the other applecation's caption... and this is what I want to change the Window title of other applecation....

is it possible?

Yes, just call FindWindow() as has already been mentioned.

I did that also, but the same problem, only my applecation's caption will be changed, not others...

void CAdfadfhgDlg::OnButton1()
{
HWND hwnd = ::FindWindow(NULL, "Title of program");
if (hwnd)
{
::ShowWindow(hwnd, SW_SHOWDEFAULT);
::BringWindowToTop(hwnd);

SetWindowText(hWnd,"My Text");
}

hmm is there any thing wrong i am doing?

thanks alot Wink | ;)

Unless the title of CAdfadfhgDlg is "Title of program", the code you have should work.

I assume that hWnd is supposed to be hwnd. Yes?

Yes hWnd = hwnd, but i deleted it also as you said and used
SetWindowText("My Text");

I have tried to do it with many programs.... but it didn't work...hmmmm

I hope that you have other selution...

thanks alot Wink | ;)

This is obviously not going to work as the function is being called in the context of your dialog. The net result being that your dialog's caption gets changed.

Perhaps you should explain what you are actually trying to do. If we knew the whole story, we could make more informed suggestions.
