You can use CreateFile with the GENERIC_WRITE and CREATE_NEW flags and check if it fails.
|
|

Whether you can create a file on a disk driver at a specified location may depend on more factors than a list of allowed unicode characters burnt into windows. One such factor can be the filesystem of the drive you are writing to. For this reason I think the previously mentioned CreateFile() test is probably one of the best and most reliable solutions.

well I want to make career in programing and i am very good in c programming which i learn ownself, now i would learn next which programming language which have better career scope ! is it good to learn java ?
please anyone help me ?

Java and C# are pretty popular and I would say they are definitely safe choices even in long term. A better questions is: what kind of stuff do you like working on. If you are programming just for money then a rarely used "exotic" language (cobol, haskell, erlang, ...) at the right place and the right time can bring pretty good money.

pasztorpisti,
Very interesting observation... money value erodes where masses go....

This is the real world. You are trading one of your most valuable resources with your employer: time

You should learn English first.

Having been laid off way too many times, I've gotten a good take on demand. The hottest thing right now is WebServices using C#.NET. Java is up there too, especially Android, but falling fast in that category. Alas, my favorite, C/C++ is not.

I would suggest that you learn one language, which you already are, from what you write. Then, it becomes a simpler matter to translate that knowledge into another language. What is most important, in my opinion, is the ability to solve a real-world problem using a programming language; rather than mastering the nitty-gritties of a programming language itself.

Hi,
I am using the 2 step process CWinThread constructer and CreateThread to Create a UI thread
and I am getting a Access Violation somewhere in CWinThread::CreateThread
From the debugger I can already see that the thread has been created as the thread id from
DEBUG->threads matches m_nThreadID
The address where the access violation occurs matches the pointer to my derived CWinThread pointer
threadptr[I}
threadptr[i] = NULL;
threadptr[i] = new SockCLeintThread(start_port);
if (threadptr[i] == NULL)
m_pMainWnd->MessageBox((LPCTSTR)"SockClientThreadFail",NULL,MB_ICONERROR);
threadptr[i]->CreateThread(CREATE_SUSPENDED,0,NULL);
|

I have no idea whether this is connected but you should not be casting an ASCII string to a LPCTSTR ; the two may not be the same. Use the _T() macro to ensure your strings are generated to the correct mode for the project.
Use the best guess

fixed that up however that statement was never executed
I inserted this test
ASSERT(threadptr[i]->IsKindOf(RUNTIME_CLASS(SockCLeintThread));
|
|
|
|
|
Which means what?
Use the best guess

I don't know why I cleaned up my laptop and all of the sudden my code doesn't
work anyway a couple of points
After I create my CFramewnd and do a Showwindow it doesn't have a window handle its nulls
The Thread after creating the object
CWinThread->wm_pActiveWnd and CWinThread->m_pMainWnd are both NULL I populated via the debugger and CreateThread worked
|

Does your thread func start off by calling that AFX_MANAGE_STATE macro (or whatever it is called)? MFC threads need to do thkis else they screw up like this with all sorts of exceptions.
|
|
|
|
|
I populate both the
Main and active window of the thread
With my CFrameWnd * an that seemed to do the trick
Thanks
|
|
|
|
|
I believe AFX_MANAGE_STATE is only needed when exporting certain functions from a DLL which use MFC and load DLL resources.
|
|
|
|
|
I am sure I have had to use it in threads in MFC apps. Its been a while and of course it use could be required in many situations.

Look at the underlined section. What are you hoping to achieve by the cast? If you're compiling for non-Unicode it does nothing and if it's a Unicode build it tells the compiler not to issue an error but to shut up and assume the ANSI string is a Unicode one, which it's clearly not. Best case scenario is a garbled string in the message box, worst case an access violation because of no double NULL terminator. This is the typical fate of the cast-happy: turning a compile-time error into a runtime one. Don't cast if you don't know what's going on or fumble around casting to suppress a compiler error.
You don't need any casts:
m_pMainWnd->MessageBox(_T("SockClientThreadFail"), NULL, MB_ICONERROR);
