Definitely - it sounds like something that a) could trip up other people, and b) isn't documented as clearly as it could be.

Hi,
I am opening an application through another application using CreateProcess().
If the exe is running already I am sending a message through PostMessage otherwise I am opening run the exe and send message.
I found the running instance using FindWindow(). But some times FindWindow() is returning " NON-NULL" although app is not running.
I am confused with this behavior.
My Window Caption is "DDKK";
And My code to FindWindow() is:
HWND hWindow=NULL;
hWindow=::FindWindow(NULL,_T("DDKK"));
if(hWindow==NULL)
{
STARTUPINFO si = { sizeof(si) };
PROCESS_INFORMATION pi;
CreateProcess (CSanProApp::GetAppPath(0) + _T("abc.exe"),
_T(" und"),NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);
Sleep(4000);
}
::PostMessage(hWindow,Opendialog,0,0);
Please suggest me any solution, why the FindWindow() is returning NON-NULL value although window is not running.

Check out EnumProcesses to find if a process is running
You can also use OpenProcess, if it returns NULL process is not running etc etc.
You need to google first, if you have "It's urgent please" mentioned in your question.

FindowWindow() takes 2 parameter: classname, windowname....
Is there any method to register window with desired name.
My app using below code to register window
<br />
if( !CFrameWnd::PreCreateWindow(cs) )<br />
return FALSE;<br />
<br />
cs.dwExStyle &= ~WS_EX_CLIENTEDGE;<br />
cs.lpszClass = AfxRegisterWndClass(NULL,NULL,NULL,AfxGetApp()->LoadIcon(IDR_MAINFRAME));<br />
<br />
cs.style |= WS_CLIPCHILDREN|WS_CLIPSIBLINGS;<br />
return TRUE;<br />

Yes, but that does not answer my question. When FindWindow() returns a non-NULL window handle, how are you verifying that the application is not running?

based on the type of application the files get generated and the editor is responsible for this.
once you select a console application depending upon your choice you get an empty project or cpp/h and stdafx's files

I suggested you to write a RunTimeCallable Wrapper the last time you asked the same thing.

you will have to create a wrapper over your win32 dll in case of RCW. Call the methods of this win32 dll using a COM object.
After that you can use tlbimp to generate the type lib.
and this can be used in C#

Hi All,
Can someone point me in the right direction? This is a reference to the article: "Synchronized multi-threading in C++ (No MFC!)"
Synchronized multi-threading in C++ (No MFC!)
I have been using the thread code and it worked well for me. But this time around, nothing has changed and it returns an unhandled exception on "thread::wait", line "return false" when "wait("MyMutex")" is called during a receive from a worker thread.
unhandled exception in kernel32 (0xE06D7363) on Thread::wait ( line "return false")
Thread::wait(const char * 0x004768e8 `string', long 0x00001388)
Thanks for your help.
Code Section
bool Thread::wait(const char* m,long ms) {
HANDLE h = OpenMutex(MUTEX_ALL_ACCESS,FALSE,m);
if(h == NULL) {
throw ThreadException("Mutex not found");
}
DWORD d = WaitForSingleObject(h,ms);
switch(d) {
case WAIT_ABANDONED:
throw ThreadException("Mutex not signaled");
break;
case WAIT_OBJECT_0:
return true;
case WAIT_TIMEOUT:
throw ThreadException("Wait timed out");
break;
}
return false;
}

Assuming that TabCtrl_HighlightItem() indeed does not work, how about changing its caption (by appending a '*' character)?

OK - I see. So...how is TabCtrl_HighlightItem not working for you?
I've added a tab control to a sample project I have> It's MFC, but I've used the TabCtrl_HighlightItem macro to highlight items. Here's the method I have - it reacts to an edit control changing and cycles through the tabs of the control (the current tab index is in tabIdx_), toggling the highlight state.
void CaaaDlg::OnEnChangeEdit1()
{
tabIdx_++;
tabIdx_%=(TabCtrl_GetItemCount(tabs_.m_hWnd));
bool isHighlighted = TCIS_HIGHLIGHTED == tabs_.GetItemState(tabIdx_, TCIS_HIGHLIGHTED);
TabCtrl_HighlightItem(tabs_.m_hWnd, tabIdx_, isHighlighted?FALSE:TRUE);
}

Hi,
I am running a flash activeX in a window in which DirectX is rendering. As DX is drawing on top of flash, it creates a flickering effect where flash is placed (first flash and then DX draw the same area).
As this is a 3D game, ideally I would like to be able to switch between flash and DX seamlessly. So I am able to open and close flash during the game with the same 3d world in the background.
The different options I have tried to allow flash and DX to co-exist:
1. Turning off DX rendering during flash's rendering. This stops 3D rendering and only flash is displayed.
2. Creating a hidden child window and attach flash activeX to that window. Then copying flash's frame using OleDraw on DX surface. Frames are copied fine but the issue here is that flash does not receive windows messages and activeX stops running.
3. Creating a separate pop-up window with flash running inside. This runs fine but flash window is separate from my 3d world.
Unfortunately it seems there is no way to tell flash activeX when to render its frame (maybe WM_PAINT?). Running flash in a hidden window and copying frames is something that gives more options in terms of flash's usage inside the game.
Any ideas on how to achieve seamless flash and DX rendering?
Regards,
Hasan
