While bdiamond most likely provided you with the answer, you might also want to know that the first character in a CString object is accessed via the [] operator, like:
CString str;
if ('c' == str[0])

}
where envp is a table with the names of the environment variables...

For user-specific variables, use:
HKEY_CURRENT_USER\Environment
For system-wide variables, use:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

"HKEY_CURRENT_USER\Volatile Environment"
I think this was also there

I developed a simple program in vc++.It stores data in a .dat file.the exe stores data properly when i run the program under vc++ environment.But as soon as i link the exe on the start menu the exe runs,but it not stores data in .dat file.Give me a solution of this problem.
|
|
|
|
|
It sounds like the application is using a relative path instead of an absolute path to the .dat file.

do you put into the start menu a shortcut to your program, or the executable itself???

Have you set the working directory accordingly? I assume your dat file is in the working directory.

usually when I want to send an array to a function that is declared like this:
int array[10];
the function header is like this:
void DoArray(int* array, int nCount);
then I still reference the array indexes like it was a regular array. But I've also seen this:
void DoArray(int array[], int nCount)
what's the difference, and is one better than the other?

no difference for me
in all cases, int array[]; and int *array; declares a pointer to signed integers...

It helps if you remember that the following two statements are the same:
array[5];
*(array + 5); See here for more.

In the end none.
However for the sake of other programers, it is nice to see
void DoArray(int array[],int nCount);
as that tells everyone you intend to use an array. int * can have many meanings other than an array. In example code like this it is obvious, but in the real world it is more like to look like:
returnValueName doSomeStuff(struct names validNames[],int count, OperationCodeList Op)
Now consider the case where names is known to be a linked list, if you had used the *validNames form maintainers (who have to be in and out quickly) will not realize something strange is going on.
Of course I would expect a comment someplace that exmplains doSomeStuff takes an array of linked lists, each list covers one gender. But will anyone recall in latter years that this function is mostly used to cover aliens from phlanix-minor who have 3 distint genders.
Unfortunatly coming up with a real world type example is tough, but I hope you can enjoy the above, and see the point.

It can? I only know it to have one: a pointer to an int.

err... well... if your code is well written yes. If it is less well written it could be a pointer to an array of ints.
In the real world though, I've seen code that takes an int *, which is then type cast to a pointer to a pointer to a struct. It works (I don't want to know how much time was waste debugging it before I got here, this "int" is passed all over in the code), but it is ugly.
In the more complex cases though the argument could be a union of a couple different pointers, or an int. Ideally we would avoid such code, but sometimes there is little choice. Remember the example I came up with, where the pointer was to a linked list of structs. Pointer manipulation often gets really messy in my experience.

I get this warning everytime I build my project in release mode, with whole program optimization turned on:
ClippedPlane.obj : warning LNK4218: non-native module found; restarting link with /LTCG
This warning appears exactly once for each project, apparently for the most recent module. I.e., before I created the ClippedPlane module, it appeared for the EmitterFactory module, which had been created just before.
Any ideas?
Cheers, blackmesa.

This warning can happen when you linking an obj which was compiled
/GL and you have omitted the /LTCG switch from
the link line.

Thanks & Regards,

For starters, you'll need to study up on ring-0 drivers. To my knowledge, because of HAL, that will be the only way to get access to that level of the hardware.
I'm curious why your application needs to know such information.

IOCTLs might give you what you need. You need to find the command to send the drive on your own. For Scsi drives, T10.org will help, I'm not sure about ATA drives. In any case, most modern drives automaticly re-map bad sectors. You can find them out, but each manufacture has a different command, and normally it isn't documented.
lookup up the function once you know what to tell the drive.
DeviceIoControl()
on MSDN. For Scsi devices IOCTL_SCSI_PASS_THROUGH_DIRECT, might be useful.
