Re: Strange 'minimize button' action.

By default, parent of dialog is set to NULL. Which makes application's main window as parent of dialog. Which is happening in your case.
To avoid it, you can set desktop window as parent window of dialog you dont want to minimize with main dialog. But, in this case, this dialog will appear in taskbar,too. Smile | :)

Thanks, that explains a lot. So, creating dialogs with desktop as a parent window will make those windows full separated from the application's main window? I ask because now when I create dialogs with NULL parent window, I cannot move main application's window on the top of their 'children' by activating it. It is getting the focus, titlebar is changing to active and all controls work but the window is not placed on the top of other windows. Is it also this case or something else is going on?

Thanks again Smile | :)

I have created a class whos duty is to return a full path to the requested file. In the C'tor I allocate a string and store the exe's folder. Since strings are often returned there is a szReturnBuffer[MAX_PATH] buffer. In later calls to the methods I build a path from the earlier retrieved path and append the file/directory.

Here's the relevent code:

CGameSettings::CGameSettings( void )
{
    m_szLocalDirectory = NULL;
    DWORD dwLen = ::GetModuleFileName( NULL, m_szReturnBuffer, sizeof(m_szReturnBuffer) );
    if ( dwLen )
    {
        ::PathRemoveFileSpec( m_szReturnBuffer );
        ::PathAddBackslash( m_szReturnBuffer );

        dwLen = (DWORD)_tcslen( m_szReturnBuffer ) + 1;
        m_szLocalDirectory = new TCHAR [ dwLen ];

        if ( m_szLocalDirectory )
            _stprintf_s( m_szLocalDirectory, dwLen, _T("%s"), m_szReturnBuffer );
    }
}

LPCTSTR CGameSettings::GetBkgndFolder( void )
{
    if ( ! m_szLocalDirectory )
        return NULL;
    _stprintf_s(
        m_szReturnBuffer,
        sizeof(m_szReturnBuffer),
        _T("%s%s"),
        m_szLocalDirectory,
        _T("Art\\Background\\") );
	
    return m_szReturnBuffer;
}

m_szReturnBuffer contains the correct path, but the _stprintf_s somehow sets the m_szLocalDirectory to 0xfdfdfdfd. What could be causing this?

Never mind, I couldn't see the tree for the forest. I forgot to account for sizeof(TCHAR) Blush | :O

Modify this to,

_stprintf_s(m_szReturnBuffer,sizeof(m_szReturnBuffer)/sizeof(TCHAR),T("%s%s"),m_szLocalDirectory,_T("Art\\Background\\") );

watch second parameter.

A note on 0xfdfdfdfd; see http://www.nobugs.org/developer/win32/debug_crt_heap.html[^]. You are accessing memory in "no mans land" somewhere in the code.

Thank you for valuable suggestion, but trhe above functions Service could not terminate. its Open a particular Service and ControlService means it send a reguest to the handler to enable the options of Start, Restart, Stop & etc.... i want to Terminate a running Service.

What's the difference between stopping and terminating a service?

To stop a service use ControlService() with a SERVICE_CONTROL_STOP for dwControl.

Displaying a form Form a Form ?

Happy New Year To All,

Up until now I have being using VS C++ 2005 to write Console type applications. I have been using VS C++ for about 6 months now.

I now have a need to develop a Windows Form application but I am stuck on a issue which most will consider to be pretty basic - but I need to ask anyway.

The application I am writing has a main form (Form1) and needs to show a second modal form (Form2), so to do this I have added a form to the project and in Form1.h I have #include "Form2.h"

Now under the code for Form1.h there is a lot of code, like: public ref class Form1 : public System::Windows::Forms::Form and void InitializeComponent(void) to just name a few.

Ok... where will be the correct place to declare Form2 so that I can then use Form2->ShowDialog(); ?

Hope all this makes sense Smile | :)

Regards
Fritzables

G'Day Kotesh,

Can you provide sample code on where and how I would achieve this - remember this is all reasonably new to me.

Fritzables.
