Having the process ID or HANDLE of a particular process, is there a way to find out its main window(or enum through all windows those were created by that process)? Thank you.
|
|
|
|

Ok i am new to answering question but i think your asking if you have a handle can you find out whether it is a child and then get the main window. If I am right then use:
BOOL IsChild(HWND hwndParent, HWND hWnd);
MSDN Library Lookup for IsChild
Ok so now you have checked your handle and its a child. Now you use:
HWND GetParent( HWND hWnd );
MSDN Lib: GetParent
I hope this helps

Hi,
I am having a csrollview where some data is being rendered. I want this data to be printed..I am unable to find anything on it.. can anyone help me out.. there is also a small problem.. like I have the vertical and horizontal scrollbars attched to the same.. but the vertical scrollbar is not working the way it should.. I mean if i drag the bar by mouse it either goes up (max) or below (min). I want to drag it by mouse and remain there where i leave.. Hope that both can be solved.. Looking forward to a solution from you people. Thanks a lot in advance..

It looks like you missed to add lib file to your settings.
|
|
|
|

Can be it, since I'm not using the default libraries... But I just dont know witch ones to add...

I have a function that returns a char* and would like to know which way to handle this as to avoid a leak.
If the function were in this format
char* Function(void)
{
char *szString = new char[50];
return szString;
}
And was called like so:
char *szBuffer = Function();
would deleting szBuffer like so:
delete szBuffer
effectively erase the allocated memory?
|
|
|
|
|
You need to call delete this way
<br />
delete [] szBuffer;<br />

I can do it too with delete(szBuffer), right?
|
|
|
|
|
Thanks for the reply but a subquestion. Aren't the brackets supposed to be placed after delete only in case of multidimensional array?
and if not, does this mean I have memory leaks all over my code when I have used new and delete directly? (...oh god no!!!)
eg. char *szString = new char[20]; delete szString
Or does this apply solely because it was returned from a function?
|
|
|
|
|
hmmm, I just realized that ommitting the brackets only delets the first element...I have a lot of search/replacing to do!!!!
Thanks for the help
|
|
|
|

Actualy ommitting the brackets does free the memory, but only calls that destructor for the first object in the array. The brackets tells delete to call the destructor of every item in the array. Therefor, for basic types you could get away with not using the brackets (not recommened).
If you are creating an array of objects that also allocate memory for there own use, then you must use the brackets so that there destructors will be called inorder for them to clean up after themselfs (a.k.a. free any memory they allocated).

|
|
For multidimensional array like below
<br />
int *pSomething = new int [2][2];<br />
the clean up codes will be
<br />
delete [] [] pSomething;<br />
I am not sure if
<br />
char *szString = new char[20]; delete szString<br /> \
[MODIFIED]
will cause a memory leak to your program

Congratulations. You are now officially the owner of the most stupid, pathetic, ridiculous, useless, worthless pile-of-crap post on this message board.

Why not? It seems like it would be the opposite - you can't play visual C++ because of Counter Stike.

Hi!
I have created a very simple program (a wizard application) with Microsoft Visual C++ .Net 2003. I want to make it stand-alone, ie to create an executable that doesn't need extra DLL.
I notice that my application is linked with mscoree.dll, and imports the CorExitProcess function from ths library.
Before, with Visual C++ 6, with the same compiler options, my executables didn't needed more DLL.
Is there a way to create stand-alone executables with Visual C++ .Net 2003 ? I'm using only MFC.
Thks in advance!

I notice that my application is linked with mscoree.dll,
That is because your program uses the .NET framework.
Is there a way to create stand-alone executables with Visual C++ .Net 2003 ? I'm using only MFC.
Start your program as MFC application and use MFC in a static library. Do not use managed extension in your project setting which will add clr(.NET) support to your program.
