Set the LVS_EX_CHECKBOXES extended style in CListCtrl or use 'item state images' for checkboxes (in fact LVS_EX_CHECKBOXES style is implemented with item state images). Note that LVS_EX_CHECKBOXES is not available on very old Win95 systems without IE 3.

I have written a static library with a CDialog divivative in it, and drawn a grid on the dialog, I then wanted to traverse my grid and needed to capture key presses e.g. UP '1' '2', I did this using entries in an accelerator table. I can now capture the key presses, but each key press makes a beep, is there any way to disable this beep?
also is there any way to stop the up,down,left and right keys from changing the currently focused button or component??
cheers!!

Hey...I'm writing a C++ program in straight-out API (no MFC or anything). How do I keep a window from having a maximize button? DO I put it in the class definition or when I CreateWindow? Also, how do I make it so the borders are NOT sizeable? Any help would be appreciated, thanks. - Dave

Do not use WS_THICKFRAME and WS_MAXIMIZEBOX when you call CreateWindow[Ex]. Note that WS_OVERLAPPEDWINDOW is a combination of multiple styles, including thickframe and maximizebox. Have a look at its #define in winuser.h

Can anyone tell me what's wrong with this code:
CMenu menu;
CMenu *submenu;
menu.LoadMenu(IDR_POPUP);
submenu = menu.GetSubMenu(0);
submenu returns NULL
The menu looks as follows:
[POPUP]
Menuitem 1
Menuitem 2
...
|
|
|
|
|
Everything seems to be in order... You can try two things:
1. Cut and post the menu definition from your .rc file (open with Notepad and search for IDR_POPUP).
2. Try with "Rebuild all". Sometimes the IDE looses track of changes in the resources and begins doing funny things.

Hi,
Has anyone run across this problem when after installing the August SDK this error message appears during the IDL build phase?
If so, what was your solution to get rid of it? I created a project using the ATL COM wizard and when I try to build the very code it generates this error message appears. I have done a search on my hard drive and can not locate this file. I have also tried looking for this error message on MSDN but to no avail.
Is there a preproccesor definition to get rid of XML support in a ATL COM file? This is ridiculous the COM program I am building does not require XML support, and why would MS include XML support and not have the right idl files to support just a plain vanilla build of Wizard generated code?
I have also tried d/l the latest MS XML SDK and that did not work either it did not include this file as well.
Thanks in advance for any help or comments!

I saw it on another machine I was using for a couple of days. That machine had only the minimum SDK Installed.
On my primary development machine I have a lot more of the Platform SDK installed, and it works fine. 
Hmmm, seems like it's possible to unselect some parts of the Platform SDK, which makes it impossible to compile ATL 
The bad thing is that I don't know what part it is....

Did you check COMEXCEL sample? It should be accessible from your VC++ help.

Hi
Is there a way to start my dialog-based app minimized?
Do I need to place some call in OnInitDialog?

In OnInitDialog put ShowWindow(SW_MINIMIZE);

My app can only use wav and mp3. So, how can I do to know if it is an Mp3 or WAV??
I use the CFileDialog and used GetFileExt() method to check... but it only check its extension...
HEEEELP!

You'll have to read the beginning of the file. If it is a WAV file, bytes 0-3 will be have the ASCII chars: "RIFF" and bytes 8-11 will say "WAVE". Here's an example of the beginning of a wave file:
RIFFR) WAVE
-------------------------------------------------------------
01234567891011 -- Bytes
I'm not quite sure about an MP3 but it should be similar. Just do some research on the file format.

I have a project that has 2 versions of the exe (a 'lite' and a 'pro' version) and I want to do as much code sharing as possible. I know that using #define has fallen out of vogue for storing constants, but is there a 'new' C++ way of doing code sharing without using #defines as switches? My current in-mind solution is to create multiple build configurations and set different compiler switches for each one, and then wrap dependent code within those defines (i.e. "#ifdef _PRO_VERSION", etc).
Is this the way to do it? I've also played with having multiple 'projects' within the 'workspace' but I think this would complicate code sharing beyond what I'm willing to deal with.
Any thoughts on the subject would be greatly appreciated.
Thanks!

#define and #ifdef is still my preferred way of doing it. I too would be interested to know if there is a better way.

I have seen some workspaces which use multiple projects and I thought they made things look more complicated than they actually were (mind you I am quite new to VC++). My personal preference is the #ifdef approach using one project in a workspace, hope this helps makes your mind up on the issue.

Do not create new projects, they are not designed to do that; just for multiple configurations. Use #ifdefs, but without #defines. The symbol which controls which functionality goes into the binaries should be defined in the Settings/C++/Preprocessor definitions. The only difference between Debug-Pro and Debug-Lite (and corresponding release versions) config should be the presence/absence of _PRO_VERSION.

That's precisely what I did. Thanks for the input, everyone.
One additional piece of info that turned out to be very important... if you're using conditionals with your resources in order to make them selected into one configuration or another, you must additionally put the preprocessor define in the box under Settings/Resources/Preprocessor definitions or the resource compiler simply won't see it.
That killed about half an hour. ^_^
Thanks again for all the input!

Ifdef - endif is preffered method - indeed.
But there is another method often used too.
You can create two projects. Common files can be included in both projects. If some functionality needs to be in pro version, You can write empty function/class in version lite. Both will link, but only one will have real implementation.
Which method to use? It depends on the number of code/files and Your preferences.
I personally use ifdef method if there are not many changes.
