Which is what I showed. If, however, you need the dialog to be otherwise visible, see here, and here (about 3/4 way down).

In the future, please explain all of your requirements up front so that we do not provide you with less-than-helpful suggestions.

You make your main application window a child window of a hidden parent window.

stdcall_api & troubles

Hello,

Being a very noob at c++, i managed to screw it up completely with this little piece of code

#define stdcall_api __stdcall

Now, at the time, i did not know this would hurt me in so many ways that would make the Spanish Inquisition proud, but apparently this had the effect of generating me 272 errors , all located in winnt.h and winbase.h, in all my Visual c++ 2008 projects that i have and need to build.
My question is: can i get my projects building again?
Thank you very very much,
A noob @ c++

just a guess, in what order are you #including your headers, and where do you #define you stdcall_api ?

You probably meant the other way around since __stdcall is a reserved word, i.e. you want the identifier stdcall_api to be substituted with __stdcall during the preprocessing phase, right?

The errors you got are from the windows header files wherever __stdcall is substituted by stdcall_api which is an unknown identifier.

Do it like this:

#define __stdcall stdcall_api

Forget that the above ever existed, it's embarrassing.

no Roger, you're going to replace every occurence of __stdcall with stdcall_api (which is not defined, so leading to errors).
what the OP wants is the opposite, and remember #define works "the opposite" as typedef Wink | ;)

so he wrote it well ; the error is elsewhere.

Yeah, plus, i do not see why it would affect my other builds or this one, if i take the #define out.
I think i have stumbled upon something very strange with this stdcall_api.

Roger, believe me or not, your post actually helped me, so it wasn't a complete loss of a post.
First of all, thanks to Roger and toxxct for your posts.
So this is my fix:
I did a compare in the sdk between v5 and v6 in the include folder and looked at winnt.h
Where the stdcall_api was mentioned in v6, i changed it back to v5 which strange enough was __stdcall.
I have no clue as to how that was changed in there (i mean __stdcall being replaced bye stdcall_api) but this fixed it.
They should have a #ifdef NEWBIE_IN_C {code for restricting access to this super sensitive keywords} #endif.

Hi,

I am using GetFileSize() to get the Hard Drive Size but this function is getting fail. Code is here:

DWORD    dwFileSizeHigh=NULL;
DWORD	 dwFileSizelow=NULL ;

dwFileSizelow = GetFileSize(m_hFile,&dwFileSizeHigh);

And what is the use of High and Low DWORD. I try to get the information from MSDN but could not understand.

What is the last error code? Add @err,hr to watch window. You could see the last error description. Your code seems fine. May be something wrong with your file handle. Anyway check the last error description.

The GetFileSize() api returns the total file size as 8 bytes that's by using two DWORDS. The dwFileSizeHigh stands for the low order 4 bytes and dwFileSizeHigh stands for high order 4 bytes. For getting the real file size, you should read them together.

Regards,
Jijo.

To get this you should use GetDiskFreeSpaceEx().

You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.

How does getting the size of a file give you the hard drive size?
Or did you mean the size of the file on the harddrive?
