SendMessage question, how do I use it?

[koden]

How do a do a SendMessage that resizes a window?

I have a progress bar and would like to send a message to it to resize. I only know how to make it step etc., but how do I resize? What's the message to send? what are the lparam and rparams?

also how do I insert new components into the dialog? What message do I send then? Do I need to create a custom message handler? And if so, how?

thanks

AFAIK there is no message, which resizes the window, but you can use SetWindowPos (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windows/windowreference/windowfunctions/setwindowpos.asp) to do that.:

void ResizeWindow(HWND hwndMyWindow, int iNewWidth, int iNewHeight)
{
SetWindowPos(hwndMyWindow, NULL, 0, 0, iNewWidth, iNewHeight, SWP_NOMOVE | SWP_NOZORDER);
}

actually that's almost it... but I'm sending a message via an InstallShield program. It doesn't have that exact function.

Any ideas?

You might want to try sending WM_SIZE.

[koden]

that is just a message saying the window "was" resized. anyone else?

[koden]

is there a way to do a custom message that calls a function inside of the program you're sending a message to?

[Mike Harnad]

that is just a message saying the window "was" resizedThat's correct. However, you can use it to resize the control if you pass the new size in LPARAM.

awesome, I will try that out, thank you.
