Have you set WS_EX_LAYERED style? This style is necessary for the SetLayeredWindowAttributes() function to work.

Does this page[^] help? It's talking about how to save files with different encodings in VS2005, using the File Save dialog.

VS editor now supports Unicode characters as well (for strings to be used in the code). If you don't know what Unicode is, I suggest you to please read up on that.

Hi all,

I have a list control in which there can be very large number of items and there can be very few items also.....

Property of my list is that it is almost sorted.....

So, i wanted to know that which sorting alogorithm will best suit this situation.....

Thanks in advance

The one you don't have to write yourself - the sort algorithm[^] in the C++ standard library is pretty much good enough for most cases.

BTW - can you quantify your "very large number of items"? My very old and slow iBook will sort a million (random) integers in 200 milliseconds using std::sort - that's reasonably quick...

Why not rejig your dialog based app into a non-document SDI app which uses a form view? That gives you the control layout capabilities of a dialog, together with the menu, toolbar and command routing capabilities of SDI.

This page[^] gives good advice, including tips for converting a dialog based app to SDI.

TAB and Escape keys are not working in windows created using CreateDialog

Hi,

I have created modeless dialogs in MFC using CreateDialog() and dialog is successfully shown.

void ParentDialog::OnButton1() 
{
	// TODO: Add your control notification handler code here
	HWND retcode = CreateDialogParam(NULL, 
		MAKEINTRESOURCE(IDD_DIALOG2),
		NULL, 
		MainWndProc);
}

In message handler, added the following

int APIENTRY MainWndProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) 
{ 
	
	switch(uMsg)
	{
	case WM_INITDIALOG: 
		ShowWindow(hwnd, SW_SHOW);
		UpdateWindow(hwnd);
		return TRUE;
		break; 
		
	case WM_COMMAND: 
		if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL) 
		{ 
			DestroyWindow(hwnd);
			return TRUE;
		} 
		break; 
	} 
	
	return FALSE; 
}

After dialogs are displayed, when I am pressing hot keys or escape from the child dialogs, it is not working.

Please help me.
Thanks in advance.

The GetCursorPos API can do that for you.

Microsoft does have a script engine that you can use to run VBScript and JScript from C++, but that is an overkill.

I'm sure all that javascript does can be done in C/C++.
And that would be the way to go on Performance, Size etc.

Getting Linker Errors when I compile a CLR Library which uses Native C++ Library

I have a CLR Application where I am trying to write a .NET wrapper over calls made to native C++ Library. I am using VS 2008 but libraries are compiled in VS2003 or 2005. I am getting some linker errors on linking. Strangely, every error is 1 of these 3 unresolved external symbol ones -

1. std::locale::facet::_Register
2. std::ctype&::_Getcat
3. std::strstream::strstream

AFAIK, mixing different runtime models will work some time, but not supported. I am not sure though.

Make sure you know which one it is, (VS2003 or 2005), 'cause you're going to have to link to its C++ runtime library (MSVCP71 - VS2003 - or MSVCP80 - VS2005). Even then, it might not work, because of mismatches in the C run-time library versions.

Catching messages from remote control [modified]

Hi,
I would like to write an application which would let me use remote control from my TV card to turn on some apps like music player. The receiver of signals from my rc is connected to TV card. There is also an application which receives the messages when I press some button on remote control. The problem is that, I can't catch all messages using the WH_GETMESSAGE hook and WM_USER parameter for MSG structure. I mean, when I press buttons which are responsible for turning on TV and radio, my application receives a message, but if I press another button like "1" or "Mute", nothing happens. I also have tried using WM_COMMAND and it works, but only if the TV is turned on. And here is my question: Is this possible to catch somehow messages connected with another buttons when my TV is turned off?

Thanks in advance and sorry for my english.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
