I would like to know if there is a solution to use the class compiled in the exe file...
I need this for two reasons:
1. the class has some functions which communicate directly with the main program. (for example I have a function to create a new document (image), which calls the CWinApp::OnFileNew(). This can't be compiled in a lib file).
2. I would like to add later some new functions to my CImg class (the old ones will remain the same), and I want the older plugins to remain compatible with the main program.
Thanks again,
kbarni

Hi
I have one Windows Service made in Visual C++, which runs on Windows 2000 Professional. My this service runs one more MFC exe when I start my service.
My Dialogbased MFC application uses the Skype API and sends and receives the messages using give functions.
It's working completely fine when I run my MFC application directly. But when I try to run my application using windows service that I have developed, it doesn't receive or send any message. Still my other functions (i.e functions other than Skype) works fine.
So what seems to be the problem? Any idea how to overcome this?
Thankx and regards in advance

Q1: "atof" is locale-dependent function, in "atof_l" locale could be managed but it needs "xlocale.h" file. What platform do i need in order to have "xlocale.h"?
Q2: In MSDN there is "_atof_l" function, but there are only 2 results in google about it. In MSDN it is said that it needs "stdlib.h" and "math.h", but there is no declaration of that function in these files. Does any one knows what it takes to compile the code with "_atof_l" within it?
Q3: What is the general method to create locale-independent software? Writing setlocale("English") in the main scope? Use of pragmas?
Q3.1: In our project we have lots of DLL-s which are unaffected by the "main" setlocale function call. Does any know a better way to change the loaded DLL-s locale, without changing every DLL code?

Hi guys
I've got a friend expert in old 8086 ASM but never programmed in C++.
He's asking me how to combinate both asm and c++.
The answer is simple (an example of MSDN),but he asked me some questions that I can't answer.
1. What is the set of instructions compatable with actual PC's? (I suposse that the minimum, more or less, has to be Pentium set of instructions, isnt it? Where can I get the full set of instructions?
2. Is MMX still operative in new PIV? If affirmative, where is possible to get the full set of instructions and examples? Books?
3. Is there a good book about ASM and VC++ combination or there is not so much than MSDN?
Thanks in advance

But be sure that its a 32 bit world out there. not the old 16 bit.

use CMemDC to draw, search on google to get the class its very popular

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.
