Exactly

Any functions that may help? int main(int argc, char* argv[])
Never mind Smile | :)

I hope the "exe" you meant is the exe that loaded the dll. if so can use the following methods.

1. Call back functions
2. Sending/posting message
3. Shared memory and Events...

.... mmmmm ..... no. It's a dll starting the exe (application), and I want to 'pass' the application a value.

I can put the value into a temp file from the dll, and the application can read the value, but I just though, is there a better way?

Thanks for the response

Then what is the problem?
if ur using the ShellExecute() function..set the command line arguments to the "lpParameters" of the ShellExecute() function.

And from the EXE you get this command line using the GetCommandLine() funtion.

Not sure really, wanted some confirmation I think.

how do i draw a line inside a picture box? i am doing this in mfc. and its a dialog based application.

Rajkumar R12-Mar-08 23:13

you can draw by getting the Client Device context, CDC and use CDC::LineTo.

I prefer to subclass it and draw it in its Paint handler.

Seriously, I would like to know from you a better solution and a simpler solution for this problem.

I don't know of one! Smile | :)

What is simpler than drawing in response to
WM_PAINT? Pretty much the fundamental process in Windows GUI programming.

I'm just saying, that since the OP seems to ignore this advice, I can
only assume (s)he wants something simpler. If so, I'm out of ideas.

You can get a handle to picture control(HDC) and use of LineTo,MoveTo.

thnx

Hope the readonly style and disable styles are not set..

BTW when u try to type, does the caret blinks on edit control? Also check the following..

1 .Set some text to that control using SetWindowText and check whether it is gettingg displayed.
2. check WM_SETTEXT message is handled in edit control
3. check WM_PAINT/ WM_ERASEBKGND/ WM_CTLCOLOR message is handled in edit control

It's possible the edit control is disabled. I think the method to enable it is CWnd::EnableWindow (BOOL).
