C / C++ / MFC

If it's just going out of scope, then you surely don't need to do anything - the destructor should take care of it for you. If you want to reuse the array, then DestroyData looks like a winner, if you want to kill the existing array as well as everything in it, then Destroy() will do the trick.

If you're using MFC then you can run in debug mode (F5) and when you close VC will let you know of any memory leaks, so if that is your concern ( for example, it's a COleSafeArray*), then that is a good way to see if you've leaked memory or not.

a Console Question ?

Hi, All.
=======

I have an API console application.
Does anyone know if I can and how to change/set the icon ?

BTW: come to #CodeProject on DalNet (mIRC)

If you need to support many Windows flavours then give this a try;

TCHAR szTitle [ 1024 ];
::GetConsoleTitle ( szTitle, 1024 );	
HWND hWnd = ::FindWindow ( NULL, szTitle );

if ( NULL != hWnd ) {

	HICON hIcon = ::LoadIcon ( ::GetModuleHandle ( NULL ), 
		MAKEINTRESOURCE ( IDI_MY_ICON ) );

	if ( NULL != hIcon ) {

		::SendMessage ( hWnd, WM_SETICON, FALSE, 
			reinterpret_cast<LPARAM>( hIcon ) );

	} // if ( NULL != hIcon )

} // if ( NULL != hWnd )

Ofcourse you'll want to play nice and free the icon resource when your done, but you get the idea.

If your using Win2K you should take a look at GetConsoleWindow function and use it to replace the FindWindow code listed above (because depending on the console's title the above code might no always work as expected).

Thanks.

Re: Another Console Question ?

Almost forgot...

Because I'm using a console application I prefer not using resources,
I think I would like to load it from a file.

I'm not checking the MSDN, 'cause... I'm lazy I guess.;)

If you can help me, ... Thanks.

::LoadImage is what you want.

HANDLE LoadImage(
HINSTANCE hinst,
| LPCTSTR lpszName,
UINT uType, = IMAGE_ICON
int cxDesired, = 0
int cyDesired, = 0
UINT fuLoad ); = LR_LOADFROMFILE | LR_DEFAULTSIZE

CListBox::ItemFromPoint()

From MSDN:
Note Because the Win32 message LB_ITEMFROMPOINT works only with Windows 95, ItemFromPoint, which wraps the Win32 message also works only with Windows 95.

I am using Win98 and it works fine, does this function work with NT/2000/XP Confused | :confused:

and if not, what is the alternative?

GetCurrentDirectory in Embedded Visual C++ 3.0

22-Oct-01 18:57

Works fine under Windows 2000. The possibility that a message would be removed ( thus breaking software for newer OS's ) seems odd to me. I reckon you're probably pretty safe to use it.

I am trying to find the current directory of my application on a HPC2000 operating system using Visual C++ 3.0 Embedded. The function GetCurrentDirectory does not seem to exist for the embedded environment. Anybody solve this problem, or have any hints to get me started.

Not sure if this is what you're after, but it will get you the dir that your exe is in. Ive tested this on a PocketPC device. I dont have any HPC's available atm.

//This will get you the path + filename of your exe file.
TCHAR szModule[512];
DWORD dwResult = ::GetModuleFileName(AfxGetApp()->m_hInstance, szModule, 512);
if(dwResult == 0) return;

// this will strip the exe name from the string and leave a trailing \
CString strInstallDir = szModule;
int pos = strInstallDir.ReverseFind('\\');
strInstallDir = strInstallDir.Left(pos+1);

Ooops... the last part was from a non-unicode project.

int pos = strInstallDir.ReverseFind(L'\\');

will fix it.

I don't think it's possible since WM_COMMAND is fired only for regular left-button clicks. Christian is right though, why do something so weird?

How can I launch a new child frame from a inherited CView class??

Christian Graus22-Oct-01 21:07

22-Oct-01 21:07

Do you mean a new instance of a CView derived class in an MDI app, or do you mean a new child window that is the child of a CView derived class ?

The idea is this:
Now that I've got the communication between my CMouse and CHtlm2View classes, I want that based in some information that my CMouse class give to my View class, launch a new chils windows with another html page displayed on it. I dont' know if this can be done from the View? Or shoul I launch it from the CMainframe class?? Anyway I don't how to do it....

Christian Graus23-Oct-01 10:36

23-Oct-01 10:36

Your document template ( which is in CMainframe ) has the method CreateNewFrame, which takes a pointer to the document associated with the view and returns a CFrameWnd*. Then you need to call InitialFrameUpdate on the template also, passing in the frame pointer and doc pointer. The best place for this is your document, because you can use theApp global variable to access the template, and 'this' for the document.

Can't use theApp variable. Doesn't recognize it!!

Christian Graus24-Oct-01 12:27

24-Oct-01 12:27

try putting an extern statement in, if it's an MFC app wizard generated app, then it is there. You can get the app as easily with AfxGetApp() if you need it.
