I have the free version of Visual C++ 2008.

In reply to this query, you told me to read http://msdn2.microsoft.com/en-us/library/ms533798.aspx about GDI+.

I went from there to its subpage about "Setting JPEG Compression Level", which has an example coding. Thus, I first inserted the line
#include <gdiplus.h>
in a small test program. The result was 104 compile errors and 8 warnings, of which the first were:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1>c:\program files\microsoft sdks\windows\v6.0a\include\gdiplusimaging.h(74) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

Please, what should I do now?

Probably you have to remove

#define WIN32_LEAN_AND_MEAN

in your stdafx.h header (or wherever else it is in your project).

I then inserted the instructions:

GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
Image* image = new Image(L"C:\\Poser4\\~~~~~.bmp");

and the result was successful compilation and these 7 linking faults:

Re: How to call Windows's built-in routines to read and write JPG files?

You have to link to Gdiplus.lib too.
Select Project properties menu item, the choose Configuration Porperties->Linker->Command Line and add Gdiplus.lib to the additional options textbox.

Custom Drawn Dialog

Hi,

I am trying to implement my own dialog with its own style and myDialog wraps CDialog.

All works fine except Title bar buttons:

http://img517.imageshack.us/img517/2269/mydialoggv0.jpg[^]

(as you see on the picture)

When i minimize or maximize myDialog, some times its CDialog is drawing its titlebar buttons above my buttons.

Does anyone knows anything about this?

Thanks,
Cem

you can remove WS_MINIMIZEBOX and WS_MAXIMIZEBOX style for Dialog. then draw them youself.

Are you have gtalk ? please add me: xiangyangzhao@gmail.com

Hi all,

I would like to know wheter it is better to declare a structure in a class or in a global space with regards to memory usage?

Can anyone please give me some advice?

Many Thanks in advance

Memory usage should be the same. Anyway, IMHO that isn't the point: nested structs are declared to avoid name collisions.

If the structure was declared globally, it would always exist on the stack. If it was declared within a class, it would only exist if an instance of the class also existed.

The above is true for an instance of the struct not for the struct type itself.

but a type itself doesn't exist in memory... only instances of this type.

CPallini17-Dec-07 4:55

17-Dec-07 4:55

OK. But the OP, IMHO, refers to the struct type declaration (i.e. to the memory usage of the instances of either globally declared struct type or the class nested struct type).

BTW your sentence isn't completely true (missing static members? Wink | ;)
