Hello everyone,

What is wrong with my simple code below? I have tried to figure it out in 40 minutes, but failed.

1>main.cpp
1>c:\program files\microsoft sdks\windows\v6.0a\include\wininet.h(58) : error C2146: syntax error : missing ';' before identifier 'HINTERNET'
1>c:\program files\microsoft sdks\windows\v6.0a\include\wininet.h(58) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

#include <wininet.h>

int main()
{
	InternetOpen ("Test Agent", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
	
	return 0;
}

thanks in advance,
George

Do you link to Wininet.lib?

Somethings seem HARD to do, until we know how to do them.

It is a compile error, I never link. I think during compile phase, import library is never used. Correct? Smile | :)

Actually, I have added Wininet.lib to Project --> Properties --> Linker --> Input --> Additional Dependencies. Is that the correct place?

George

Compiles fine here
MinGW 3.4.5

Have you tried including windows.h before wininet.h?

I've had errors similar to those before when including in the wrong order or
not including something explicitly (which in the end just affects include order)

Thanks, after including windows.h before wininet.h, the compile passed. So weird. Smile | :)

Here is the compile pass code.

#include <windows.h>
#include <wininet.h>

int main()
{
	InternetOpen ("Test Agent", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
	
	return 0;
}

regards,
George

Actually, there's nothing weird. To start with it, the first error message that you got was:

1>c:\program files\microsoft sdks\windows\v6.0a\include\wininet.h(58) : error C2146: syntax error : missing ';' before identifier 'HINTERNET'

When you open the error location, you find this:

typedef LPVOID HINTERNET;

So, the error clearly suggests that LPVOID is not being recognized as anything at all - a semicolon is expected there. If you try to locate the definition of LPVOID, it is within WinDef.h

But, WinDef.h is included in Windows.h - so, Windows.h must be included before wininet.h Smile | :)

Just wondering why we should help you to set the text for an edit-box in a keygen?

Try typing "Adobe Creative Suite 2 by cvs/SSG" into google and checking the results.

pallini..thnx..but i need a full running code for comparing 2 bitmaps..
i have posted my code but i cant understand what is wrong in my code...
can you help please..

1.

Well, you're "getting there";

Me thing you do not need to keep arrays of COLORREF or the r and R arrays
You should be able to get the size of the bitmaps dynamically (because a bitmap of 48 pixel is really small)
No need to get the DC twice.

Now that you have the color for the same pixel position in both bitmaps; what should you be doing with them ? compare them ? maybe ?

thank you for the reply.
can you tell how to make changes in the code. I am studying VC++ so not too much knowledge about the language.So can you help me with the code.
Yes i am comparing both bitmap for checking whether both images are same or different.

Thank You
