Maybe your wxWidgets library has no PNG support compiled in?

I've run bin2c, but I still can't use this "c image" in wxBitmapButton: wxBitmapButton *btn = new wxBitmapButton (this, -1, wxImage (c_image)); You should do something like: wxMemoryInputStream istream(c_image, sizeof c_image); wxImage myimage(istream, wxBITMAP_TYPE_PNG); wxBitmapButton *btn = new ...

Thanks for writing back. First off, all those text controls are for user inputs. My program involves them inputting the elements of up to 4 4x4 matrices. So basically you have a bunch of grids of text inputs. Is there a simpler way of doing that than I have? I think that your job will be easier usi...

Sorry, but I don't understand your question. The line:

Code: Select all

(new MyRawBitmapFrame(this))->Show();
is valid C++ code. This is exactly the same as writing:

Code: Select all

MyRawBitmapFrame *p = new MyRawBitmapFrame(this);
p->Show();
But I agree that the former is not (IMHO) good readable style.

Re: 12 bytes Memleak when deleting a *wxBitmap() ?

Perhaps you should also deallocate the structure for each bitmap: for (i=0; i<G_D_Number_Bitmaps_created; i++) { delete G_Bitmap[i]->bitm; G_Bitmap[i]->bitm = NULL; delete g_Bitmap[i]; <------ here g_Bitmap[i] = NULL; } delete[] G_Bitmap;

The wxWidgets developers will still be mentioned in my help files, because I would feel kind of guilty if I didn't mention them ;)
If you want, you might also add a link to the wxWidgets page with a button:

It reminds me when you don't remember to add the terminating null character to a string, e.g.:

Code: Select all

char buf[128], *s;
s = "some text";
char *p = buf;
while ((*p++ = *s++) != '\0')
    ;
printf("%s\n", buf); // prints some text + garbage

I strongly suggest TinyXML. It it very small, well documented and very well written (you can customize it after 5 minutes of reading the code).

You mean that you have included the wx library project in your solution? I suggest you remove that dependency and add the proper include/link flags to the compiler.
