I'm developing a dialog client application with Borland C++ 5.02 and OWL in NT4.0.
I would like to start it from an other process with CreateProcess() or by a shortcut e.g. from 'Startup' start menu folder. My problem is, that it starts always in 'Normal Window' state, even if I specify 'Run Minimized' or 'Run Maximized' states.
I do not attach code fragments to my question, since a pure AppExpert generated program may provide the symptom.
Any help would be appreciated.

1-st idea(without check): simple
send WM_SIZE message with SIZE_MINIMIZED
as wParam after start 2-nd apps. But solution, I think, other:
You must make Minimize/Maximize youself
in Apps, use parameter(and it is NOT automitic)! For make it
you can use simple ShowWindow with
SW_MAXIMIZE/SW_MINIMIZE parameter.
Thank you for your comment, Alex.
But, It is not the solution I would like to have. Generally I would like my program to start in SW_SHOWNORMAL state. But, there can be situations if a user requires this program to start in minimized. E.g. he may want to start it automatically when he logs on. For this, he should create a shortcut in his Startup start menu folder. My problem is, that the 'Run minimized' shortcut option has no effect.
After 1.5 hour I found solution!
Problem is , that GetCmdShow allways
return 10(SW_SHOWDEFAULT).
The following (from STARTUPINFO in the Win32 help) relevant:
wShowWindow
Ignored unless dwFlags specifies STARTF_USESHOWWINDOW. For GUI
processes, wShowWindow specifies the default value the first time
ShowWindow is called, if the nCmdShow parameter of ShowWindow is
SW_SHOWDEFAULT. The wshowWindow member can be any of the SW_ constants
defined in WINUSER.H.
In earlier versions of Windows, the WinMain function had an nCmdShow
parameter that applications were encouraged to pass to the CreateWindow
or ShowWindow function. The nCmdShow parameter is no longer available
through WinMain. Now applications are encouraged to use SW_SHOWDEFAULT
as the default ShowWindow command, in which case, ShowWindow uses the
wShowWindow member of the STARTUPINFO structure of the process.
....
The trick is to get the process' s startupinfo in InitMainWindow.
void
MyApp::InitMainWindow ()
{
..........
#if defined (__WIN32__)
// In Win32 nCmdShow is no longer available. The wShowWindow field
of the
// STARTUPINFO struct defines the default value for the 1st
ShowWindow.
STARTUPINFO startupInfo;
::GetStartupInfo(&startupI
nCmdShow = startupInfo.wShowWindow;
#endif
..................
//now you know nCmdShow and simple use
frame->ShowWindow(nCmdShow
}
I hope, it is a solution of you problem

I have overwritten the default OWL provided WinMain() function. It seems, that its last parameter 'nCmdShow' is always 0xa regardless the program was started with 'Run Minimized' shortcut option. Is it a loader problem? How to solve it?
