I'm still fairly new to VC++ and MFC so I'm not sure of the correct terminology to use here.
I'm developing a Windows-based application. I would like this application to be able to detect if another instance of this application is already running and, if so, send and receive information with it. How would I do that?

Thank you! I think I can adapt this code to my needs without much trouble.

Hello guys, I know that it will sound stupid - but I can't find any way of clearing the selection of a ListView control the way it is before you select an item for a first time.
Thanks for your patience  ,

ListView_SetItemState(hwndList, -1, LVIS_SELECTED, 0);

Is there a way to subclass a groupbox so that it automaticly contain, say four CButtons. ie when I add my derived class to a dlg project it will automaticly add the four member buttons. The problem for me is how i do with the resources for these buttons.
Thanx...

Do you really need the resource for the buttons?
Can't you just create them from your subclass?

Have a look in the MSDN at "__asm" if you have a MS compiler, otherwise look out for "asm".
Good luck

I need that when my windows is created it automatically execute some task.
In particular query the database using ado and displaying the results in editbox, lists, etc...
I tryed to put the call to the function that retrive the data in the constructor, but the controls are not yet created so Assertion Failure.
I went on and tryed when the window post WM_CREATE, same error, I tried with WM_SHOWWINDOW, same same.
Finally in the WM_PAINT, OnPaint, everything works perfectly.
The downside is that everytime my window is covered, resized, maximized, etc, my App requery the database, and this is a Big WASTE OF RESOURCES, especially if made on sone network.
I solved this by creating a BOOL m_AlreadyQueried.
And putting an if(!m_AlreadyQueried){...}
So when the WM_PAINT is posted the OnPaint calls the Query function, and sets m_AlreadyQueried = TRUE, the next time OnPaint is called the if evalutates false and the App doesn't query the database.
There is anther way of making this?
I mean maybe I'm wrong using WM_PAINT, but the other messages are posted "TOO EARLY".

If yo want to do it in your view class you can do it in OnInitUpdate()

Or if you are in Dialog, do it in OnInitDialog
Or, if you are in generic CWnd, you can try to do it in OnShowWindow, checking that the command is SW_SHOW and GetSafeHwnd() returns you not null and then query the database. Remember to have some flag, for example a static boolean variable inside function, then, after query, set it to false, e.g.:
...
if(GetSafeHwnd() != NULL){
static bool bFirstTime = true;
if(bFirstTime){
bFirstTime = false;
}
}
Hope this helps

Yes, WM_PAINT is no good place to stuff code in.
Register our own message and when you window is beeing created, post
it to yourself and the do the proccessing in response to the message.
If it's a dialog post it in WM_INITIDIALOG, if its a window post it in WM_CREATE.
