Thank you.

Did you think about using some sort of a CListView derived class?
These are made for exactly this purpose: Giving out texts in a view.
OTOH, you might have very good reasons to print directly on the view.
Then writing to a Mem-DC and only blitting it to screen in OnPaint would be the way to go.

Hi,
i have written a program in MS Visual C++ and installed it. After that i changed the name of the program and project and also changed the code. I want to install both versions of this program on one computer, but XP tells me, that this program is already installed. I guess it has something to do with UUIDs, but dont know where i must change it.

What kind of application are you installing and what are you using to make the installer, msi or exe?

Its a MFC program that sends data via FTP. I use msi.

create a seperate msi for the second application, don't use the same msi again, as the msi creates a uuid and inserts it in the windows database while installing.
create a new msi from scratch for the second setup

Hi,
Is it possible to "ping" windows, so to speak, to say that you know it's waiting for return of program control whilst a function is performing an operation.
basically i have a CPU intensive function which hogs all the processor time pretty much thus slowing the system down completely so preventing window updates, etc.
is it possible to ping the windows system within my main function loop to let windows do its updating stuff as usual.
...maybe some kind of Postmessage or something?
any help would be appreciated.
thanks !

Hi Paul,
I had a similar problem. In our app, we made a separte thread to do the processing and allowed the MFC thread to do the refreshing, WM handling, etc.
When the thread finishes it can use ::SendMessage to send a WM_USER+... windows message to the MFC app (you need to pass the thread the HWND)
Then your app just needs to wait for the message to come in.
regards,
Rich

IIRK, the standard technique in the C / SDK era was to make sure the processing loop did a peekMessage() call every now & then (say every 50 millisecond or XX loops.)
When you do peekMessage, the program returns control to Windows which takes the opportunity to do its system stuff, and gives other applications a turn to do things.
I think I used this for 16-bit programs under Windows 3.1!!!

Try calling peekmessage() every 50 milliseconds or X number of loops in your processing function - this gives control back to Windows for system stuff and other programs.

void main()

Xuly<int>(); // why this call bind T with "PS" type (not int)?
Xuly<PS>();
}
Xuly<int>() : binding wrong type, it must be "int" but when to be executed it bind with "PS" type.
Please help me?

Hello
I think you should check MSDN for this.
type Templates in MSDN after that select C++ Templates / Function templates.
i hope you'll get answer to your question here.
