Cannot size window using STARTUPINFO

elephantstar

I would like my newly window to open up with the given sizes. The following code maximizes the window when it gets created. Why doesn't it work? Thanks! STARTUPINFO stStartUpInfo; PROCESS_INFORMATION pProcessInfo; memset(&stStartUpInfo, 0, sizeof(STARTUPINFO)); stStartUpInfo.cb = sizeof(STARTUPINFO); stStartUpInfo.dwFlags = STARTF_USESIZE; CreateProcess(NULL, CmdLine, NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS, NULL, NULL, &stStartUpInfo, &pProcessInfo);

Look like the following is missing: stStartUpInfo.wShowWindow = SW_MAXIMIZE; Your code looks like it would show the window hidden as it memsets the struct to zero and 0 is SW_HIDE. Steve

The window does show up but it's maximized. That's not what I want. I want the window size to be set to what I defined for dwXSize and dwYSize .

Try this:

STARTUPINFO si;
ZeroMemory(&si, sizeof(si));
si.cb sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USEPOSITION | STARTF_USESIZE;
si.wShowWindow = SW_SHOWNORMAL;
si.dwX = 0;
si.dwY = 0;
si.dwXSize = 100;
si.dwYSize = 100;

An application is free to ignore the values in the STARTUPINFO structure if it wants to.

It still maximizes the window. Ryan (below) mentioned that application can ignore the STARTUPINFO struct if it wants to. So is there no way around this?

Before I started to look for ways around it I would verify the code with notepad (an application that respects it, I think) or something. I can't think of any easy way around it. You could install a WM_CBT hook with the SetWindowsHookEx API but this would involve setting a global hook (and thus creating a DLL and taking care that it doesn't crash or effect other applications).
