1. FILE * pFile;
pFile = fopen ("C:file.csv","a");
if (pFile!=NULL)
{
CString x2 = "CString1"+","+"CString2"+"\n";
fwrite(x2, x2.GetLength(), 1, pFile);
fclose (pFile);
}
2. Use ,(comma) operator for seperate the objects. use .csv file. it will open in excel.

No, OpenGL cannot load any images on its own, you will need to use an external library for that (for instance DevIL or FreeImage or maybe GLUT). But I don't know if these libraries support bmf because I never heard of that format.

sorry , it is my mistake -> bmp.
i need to load a bmp picture by openGL ,then i can use mouse in openGL to draw a point in that pic.

Then you can use DevIL or FreeImage (I think even GLUT is able to load bmp files but I'm not sure at all, I never used it). Did you look at these libraries ?
If you are interested, you can also look at my second tutorial about OpenGL: it discusses resource management but it is probably it bit more higher level than what you are looking for.

Hello folks!
Could someone please shed some light on this? I found out the hard way that the file-association technics used in Windows XP and prior to it no longer work in Windows Vista and above. Trying to modify the registry entries to create a file association for a program simply fails in an "access denied" error. So i googled around and found IApplicationAssociationRegistration[^], tried to use it but SetAppAsDefault[^] gave me "file not found". I might be wrong but i figured this means that the application needs to be registered as a "Default Program" before any associations can be done. How to do this? I found this[^] on Microsoft's site, here it tells me that to register an application as default one has to create some registry entries for the application. BUT if i try to create these entries i once again get an "Access Denied". At this point i am a bit lost. I know the documentation there says that usually the installer registers the application as a default program and that installers are usually ran as administrator, however, my program is a very small and simple viewer application which does not have nor need an installer so i want to do the whole association thing from the application itself. Anyone knows how?
Thanks in advance.

Thank you. The application i am doing is dialog based, it does not use any document and view architecture really (so no RegisterShellFileTypes), however, i feel strengthened in my belief that this whole file association thing under windows is very badly designed. I think i have now 3 possible ways i can go:
-forget about the whole file-association crample
-have the users run the program as administrator if they ever want any file associations (and i guess changing the whole idea so the program checks for file associations only if it is runned as admin because otherwise it can't change anything on it anyways...)
-try to "elevate" my program under Vista to be able to change registry entries, there doesn't really seem to be any elegant way to do this (you can't change the priviledges of the process once it is already running)
Here[^] it says to use RegOverridePredefKey to "remap" writes to HKEY_CLASSES_ROOT to HKEY_CURRENT_USER, however i do not see how this would help anything since according to the docs it is not HKEY_CURRENT_USER where any registry modifications must go in order to get one's program to be a "default program".
One would think Ms would make something this "basic" as creating file associations more...simple and "standardized".

Don't access memory that you're not allowed to.
i.e. Silly question, silly answer... 
BTW possibly if you post the offending code then we could help you.

The same way as you fix the previous error message you posted: by using your debugger. Start debugging your program (press F5) and see where the code crashes. Once there you can inspect the different variables to see if everything is as expected. You can also put breakpoints (F9) to break your program at a certain location.
You've been posting on CP for quite a long time already, it is time you learn to use your debugger properly. There's no way you can write quality software without using it. It should become your best friend when fixing problems in your application. Once you know how to use it, you'll see that it will make you gain a HUGE amount of time. So, the time spent in learning how to use it properly is a very good investment, believe me.

Use your debugger to locate the exact problem. There's no way to find the source of the problem with so little information.
|
|
|
|

Use your debugger to step into your code. Narrow down the problem, post it here with any relevant source code and the call-stack. Only then somebody will be able to help you.

HI,
I want to write c++ String Functions using STL string class on Linux OS.
Is this string class error free ?
I read some where these below lines.
" The Standard Template Library (STL) that is included with Microsoft Visual C++ 6.0 is not safe for multi-threaded applications."
http://support.microsoft.com/kb/813810[^]
is it Safe in Linux multi threaded applications ?
Thanks,
Rayalu.

STL collections are not thread-safe. You can synchronize them with a mutex when you are accessing them from more than one thread.

That means the library that comes with MSVC 6.0 was not to safe to use in multi-threaded applications even if the containers were not shared among threads. If you use a more recent version of MSVC (or even MSVC 6 with STLPort), that should not be a problem. Of course, you should still need to synchronize access to container objects that are shared between threads.

Hi,
I have the "Analog Meter Control" class by Mark C. Malburg.
I downloaded this from code project only.
Now I want to add the print facility to that control.
how could I make this, any suggestion and directions are welcome.
Thanks in advance.

I would say:"Why don't you post it in the right place?", but you've already done so. Hence I say:"Good luck!".

Hi to All,
Could you please clear my following doubt.
I have 3 class with multilevel inheritance as follows,,...
class A
{
public:
A()
{
s();
}
virtual void s()
{
printf("\nIn A");
}
};
class B:public A
{
public:
};
class C:public B
{
public:
void s()
{
printf("\nIn C");
}
};
int main(int argc, char* argv[])
{
A *ptr = new C();
}
when i create an object of C,...by theory it should call always the method S of C....am I correct?...but when I called C from A's constructor Its calling S() of C....Why so?...Could anyone please explain me the reason and some points on it??
thanks in advance

You mean it is calling s() of A, right ?
That's normal because when A is being constructed, it's virtual table is not create yet, which means that the call can't be redirected properly. So, the rule is simple: never call a virtual function from within a constructor.
Read this[^] for instance.
