Just as in that you can call LoadLibrary() on a DLL and then use GetProcAddress() to call a function within that DLL, is it possible to export a function from an exe? I know you can call LoadLibrary() and pass it an .exe and it will return a valid handle...
My end result is that I'd like to load an executable by another program (NOT run it) and determine what specific version it is...without using a version info resource within it. If I could set a function to export to return the version, that would be *perfect*.
Any other suggestions on getting at my end result would be appreciated.
Thanks,

It IS possible! In searching the internet, I came across this article:
http://www.codeguru.com/Cpp/W-P/dll/article.php/c3649/
In trying to solve this problem yesterday, I had created a Win32 DLL using the VS.NET wizard with one function I was exporting. So, I just copy/pasted the code into a new header file which I included in one of my .exe source files, then linked. That was it and it worked.
I was able to call LoadLibrary() on the exe, then GetProcAddress() for the function. Here's the complete .h needed (VERSION_EXPORTS was defined in the project properties):
<br />
#ifdef VERSION_EXPORTS<br />
#define VERSION_API __declspec(dllexport)<br />
#else<br />
#define VERSION_API __declspec(dllimport)<br />
#endif<br />
<br />
VERSION_API int fnVersion(void)<br />
{<br />
return 6030;<br />
}<br />

but you are using some dll methods to came across this : dllexport and dllimport
i never seen an application (.exe) defining some symbols that are to be exported... !!
this is done in dll generally.

I sure am...I'm sure in most cases this may not be appropriate or needed. But it fits my case perfectly. And since LoadLibrary() and GetProcAddress() both work with .exe's, there's no reason why it can't be done.
Thanks,

Hi,
I have a problem when creating win32 regions and drawing into them. The edges of the shapes drawing inside the region are distored or cut-off. For example:
CDC* pdc = GetDC();
CRgn rgn;
rgn.CreateEllipticRgn(10,10,50,50);
pdc->SelectClipRgn(&rgn, RGN_COPY);
pdc->Ellipse(10, 10, 50, 50);
pdc->SelectClipRgn(NULL, RGN_COPY);
ReleaseDC(pdc);
Although the coordinates of the region are the same of the ellipse coordinates, it still does not draw the ellipse perfectly. The edges are distorted. Is there a way I can calculate the perfect region. I also do not want to use paths as they don't work properly in win98. What could be the solution.
Thanks

Are you acconting for the pen width of the border of the object?
In that case, your region needs to be slightly larger than the actual object boundaries, since most programs leave the pen drawing code to drawn ON the object's edge rather than within it.
Since I don't see any code explicitly setting your pen, it could be any guess what it is at the time this code executes. Are you seeing distortion when the pen width is more than 1? I would not expect it too much with this code when the pen width is 1, except maybe at the outer edge of the ellipse.

Thanks for your reply. I am not selecting any pen into the device, so I assume that the default is a 1 pixel black pen. I tried making the region larger by one pixel, but the result shows the ellipse. However, there are extra little blank spaces around the ellipse. I also tried to make the pen PS_INSIDEFRAME but with the same result.

Hello,
I had some doubt regarding definition of global variables. If I have to define two global variables with the same name in two cpp files then is it somehow possible to do so..?
However I am aware of providing a definition in one file and declaring in other for usage(using extern keyword).
Example:
int i;
should be "defined" in CPP1.cpp and CPP2.cpp belonging to the same project.

Abhishek.

Global variables are only visible in 1 cpp

in cpp1.h ->
extern int i;
in cpp1.cpp ->
int i;
Then include cpp1.h where ever you need to use i

if you want a modal frame window, I think you can disable the owning frame window.

This depends on the way you are doing it but make sure the text is written after the iamge is drawn, including in the OnPaint handler.
