We need to write a server side script to answer all questions posted by George_George. Basically the script would do it by Googling and returning the first 5 links back.

The above holds true for most peaple posts. 
On the other hand, some George_George ones are indeed deep & tricky (though ofter matter academic interest) and Google is of little help about.

Thanks CPallini,
1.
I have read the link, for normal function, extern "C" only need to be added to declaration, and if containing function pointer as parameter, we need to add extern "C" to definition as well.
2.
But the link only covers functions, my question is about variables, does the same rule applies to variable we well?
3.
How about your points to my question (2)?
regards,
George

The link shows that the general behaviour, i.e. use extern "C" only on declarations, may have pitfalls. That's all.
IMHO if you use extern "C" both in declarations and in definitions then you're safe.

The article explained well all the issues.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

I need to provide http download resume support in my application. Similar to resume support present in most of download mangers.
Kindly point me to some example code or how should I go about this problem.

Of course resume depends to that web site that support of it or no.

|

That is not a problem as most of Download manger works for most but some site. That is acceptable. But how can I support download resume in VC++ for the sites which provide resume support.

Hi all,
i am writing a dll on VC6.0 which internally executes a command over command prompt using system() API. while executing the command, command prompt is being displayed on the screen.i don want this command prompt to be displayed on the screen.Is there any method which supress the command prompt from being displayed on the screen,or is there any other API which does as system() API without displaying commandprompt..?
Thanks in advance
kathir

Look up the ShellExecute() function.

What command are you executing?

hi david,
i m going to execute a "exe" file along with the parameters to be passed to the application. It would be better if i identify a routine which can perform this command line execution and also works on unix and windows as well.

Woundering what books anyone would recomend for learning c++ such as winsock and other protocols for
conecting to servers and clients the books ive read only go thro program control thanks for any suggestions.
|
|
|
|
|
for c++ you should get Stroustrup & everything by Scott Myers & an STL book
Winsock its not a protocol its a library and there are plenty of sources of info on the web
For most protocols the doco will be language neutral. There is heaps and heaps of really good stuff on this site for windows socket programming and many many other thigns
|
|
|
|
|
For C++ I think www.cplusplus.com is good for you and for protocols I have this book and its good (Teach YourSelf MCSES TCP/IP in 14 days).

I have a device context handle HDC some thing drawing on it .
can i same the image that is drawing on device context using HDC handle only
Trioum
|
|
|
|
|
Do you want to show image with other draws?
|
|
|
|
|
Are you asking...
"I have an HDC that some other part of my program (eg a library) is drawing on.
With just that HDC information, can I save the picture?"
?
I can see a few barriers to saying Yes.
1/ I can't find any function called GetHDCSize (or equivalent), so you would have to select in a new BITMAP, and examine the old BITMAP for information, then select it back. But you have to do this in the same thread as the Thing that is drawing to the HDC.
2/ HDC's are normally temporary objects, given to a program from a central pool. How you got this HDC is important. If you simply stored a HDC returned from BeginPaint, then the HDC will be recycled by EndPaint, and it will no longer be valid. If you get GetDC (hWnd) yourself, then you will be working on a different HDC to the Thing you talked about earlier.
3/ I'm now running out of ideas, as any more answers depend on details you haven't told us (yet).
Good luck,
Iain.
