C / C++ / MFC

Thank you all for your help. The example code is very close to the actual code and the problem is that sometimes, depending on the computer, because of the operator >> to deserialize the style m_pFont, several m_pFont pointed to the same memory area. I studied the problem with a minimal grid ... and finally realized that in my application I was not using this m_pFont. I modified my code so that I would no longer use it at all, destroy it and set it to NULL which definitively resolved my problem. If I don't fully explain the phenomenon, I think it comes from the fact that these m_pFont contained the same data and that the operators << consider the pointer had already been serialized as explained in the TN002: Persistent Object Data Format | Microsoft Docs ... Maybe ... Regards

The for statement breaks down as three individual expressions: for(set; while; do) : // // set : perform this or these expressions first: multiple expressions must be separated by commas // while : repeat the loop while this expression equates to true // do : perform this or these expressions at the end of each loop Note that any of these expressions (or indeed all of them) may be blank. In your code the expression in the while part is name[i], which means while name[i] is true, or rather while name[i] is not equal to zero. Strings in C are (or should be) terminated with a zero character (NULL), so the expression will be true as long as the character in question is not the terminating NULL.

Thanks Greg

Nice. :thumbsup:

If they are not used then the preprocessor will ignore them. Macro expansion happens at the reference, not at the definition. You may need to create some dummy file to get the expansions. A better idea would be to write proper documentation comments so they can be seen by anyone looking at the definitions. And I think that may also make them visible through intellisense.

See Overall Options (Using the GNU Compiler Collection (GCC))[^]. The -E option of gcc allows you to stop the build after running the preprocessor. The out put will be the expanded source. But be aware that this will include the expansions of all input from included headers so may well be quite extensive. If you run a few samples you should be able to see how to get to the source that you are interested in.

Other application can print out without problem ? Have tried to print to another printer ? Or, have you tried to run that command on another machine ? You can find more if you do some debugging on your code ...

Does it compile? It looks like the parameter CRect is missing.

0? lol, I agree. It's totally bizarre. I'll keep digging, maybe write my first article. Charlie Gilley <italic>Stuck in a dysfunctional matrix from which I must escape...

Use wxWidgets[^] GUI library, then your code will work on Windows, Linux and MacOS.

Thank you Daniel

Are you female and cute? :doh: Just kidding, but when I was back in engineering school a *very* long time ago, that never hurt.

If you got the code then please send ma at my Gmail naeemyaseen78@gmail.com

thanks, I got it working.

Sorry, I cannot help further as I don't have MFC.
