in your thread:
CString *tekst = new CString("blablabla");<br />
<br />
PostMessage(hWnd, WM_MYMESSAGE, (WPARAM)tekst, 0);
in MyFunc:

No you can not pass parameters for user defined messages in that way.
I would suggest that you thoroughly read this article[^]. It is one of the best on this site explaining multi-threading and how to deal with the many issues.

With the introduction of "hyper threading" CPU's, good luck...
But to find out how many CPU's the system thinks are available, you can use GetSystemInfo.

Yea, for now, but on Windows Server 2003 you can use GetLogicalProcessorInformation()

How can I execute an exe from my VC++ 6 application?
Thanks
|
|
|
|
|
Use ShellExecute.

Could you give me an example?
Thanks

Do look at the link in my other post (point 6.4 in Michael Dunn's C++ FAQ). You have all the examples you need to achieve what you need.

for example, if you want to execute notepad.exe from your dialog, use following statement:
<br />
ShellExecute(m_hWnd, "open", "c:\\WINNT\\notepad.exe", NULL, "c:\\WINNT", SW_SHOWNORMAL);<br />

How to find a window handle by knowing only the executable path of the windows ? 
Thanks
Olivier
|
|
|
|
|
Is the Executable running ?
|
|
|
|
|
Yes, the executable is running and I know the full path name
|
|
|
|
|
To find the window Handle you need to know which window you are looking for.Windows are basically running objects in memory. At File level it make no sense.So windows classname or caption is essential for finding the handle.you can use FindWindow(...) API to get handle..
Jast have a Look on MS SPY++ utlity. Using that you can figure out classnames /captions and also handles

Has pretty nothing to do with the window itself. You'll have to know something about the Window name, or classes. Have a look at EnumWindows().

Hello,
I have a function that receives a (void *) parameter:
GetSizeOfTypeAndDoSomeOtherLargeStuffWithIt(void *pParam);
I use this function passing a pointer to all sort of numerical variables in order to process them without overloading that function and having to maintain a lot of overloaded functions... (I can pass from &bool to &double variables tot that function).
when I do sizeof(pParam); I always get the size of the void * and if I would be passing a char I would like to get the size of the char and if I would be passing an int I'd like to get the size of an int...
Is this possible?
Thank you in advance...

Of course. Anything else would be such a serious compiler bug that the compiler would be virtually useless.
I would like to get the size of the char and if I would be passing an int I'd like to get the size of an int...
Is this possible?
No, the kind of polymorphism you are interested in is not possible. You might consider adding a type argument also, or maybe have a look at templates.
