It will make no difference whatsoever - you will still link to the same dll if it's static or dynamic. All apps under Window XP look different ( I am using it ) because of how it shows things like the system menu ( the buttons on the top right of a window ), the window frame itself, etc. Every app I have written, static or dynamic, all look the same under XP, they all have the XP look and feel about them.

Apps will look like they are under XP if they are under XP or if you hack the absolute hell out of them to try and make them look similar. Otherwise, they will look like other apps under the version of Windows you are running. Also, if you want to write using newer features of Windows that require later versions of the OS, you'll need to get the Platform SDK from the Microsoft site ( download at your peril, I always get the CD ). Note that using functions like TransparentBlt will render your code inoperable under earlier versions unless you late load the dll's required and do some checking of your OS version to ensure that functionality not supported by the OS is not offered to the user.

Explain what you mean?
Do you mean keep the interface that XP has when running your app in another OS?

You have to create so-called 'manifest file' to enable XP user interface. You can find details at http://msdn.microsoft.com/library/default.asp?URL=/library/techart/XPTheming.htm

System tray icons not showing in XP or 2k

I have programmed a system tray icon into my program using traynot.cpp and traynot.h.
When I run the program, it works fine and then I press minimise and a grey space comes up.

I know its all correct because I tried it in Windows 98 and the system tray icon shows up!
Anyone know what I can do?

Thanks

In your dialog class override CDialog::OnOK() and dont call CDialog::OnOK() in it.
The same goes for Esc, override CDialog::OnCancel() in your dialog class.

Destroying COleSafeArray ...

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 ?

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).

Because I'm using a console application I prefer not using resources,

::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()

PJ Arends22-Oct-01 16:26

22-Oct-01 16:26

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?

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.

GetCurrentDirectory in Embedded Visual C++ 3.0

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.
