Defining both _UNICODE and _MBCS may cause problems if you use "tchar.h". For example many people use the _T macro and the "_t" string functions so the same code can be used for Unicode and non-Unicode builds. Take the _tcscmp function for example. Here's a table from the documentation for this function:
|----------------------------------------------------------------------------
|TCHAR.H routine|_UNICODE & MBCS not defined|_MBCS defined |_UNICODE defined|
|---------------------------------------------------------------------------|
|_tcscmp |strcmp |_mbscmp |wcscmp |
-----------------------------------------------------------------------------
As you can see the results are not specified if both are defined. Already defining both leaves you in the reals of undocumented behaviour. In this case, with my header files, the Unicode version will be used. However, It's never a good idea to reply on undocumented behaviour in computer programming if you don't have a compelling reason.
In general, I remove the _MBCS.

I don't know, but I am very sure about the point. Defining _UNICODE will implicitly define UNICODE too. I've been noticing sometimes people suggesting questioners to define both UNICODE and _UNICODE. But defining _UNICODE will suffice. I thought will point this out now.

u r right..
i found code like this in some header file
#if defined(_UNICODE) && !defined(UNICODE)<br />
#define UNICODE

I am deaing with a project invloving huge amount of data. I am wondering what is the allowable max. value of an array in Visual C++ for Windows32 system.

It depends on the stack or heap size (depending on the allocation type you use).
For Instance, default stack size is 1MB, but you can change it (/STACK linker option).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

He's dealing with huge amounts of data. I don't think putting it on the stack is a very good idea....

Maybe it is a bad idea to deal with all the data using memory.

It all depends on how much memory you've got, how wide your address bus is, and the datatype of your array. If you have 32 bit addresses, and your array is char, the maximum array index would be (2^32 / sizeof(char)) - 1. If it's an array of short, the maximum index would be (2^32 / sizeof(short)) - 1. If your address bus is 64 bits wide, it would be (2^64 / sizeof(short)) - 1.
It all boils down to how much memory the array needs, and how much free memory you've got (virtual memory).

Have a look at FindFirstFile(), FindNextFile() and WIN32_FIND_DATA
Somethings seem HARD to do, until we know how to do them.

And in the end use of FindClose

int getFileCount()
{
int count = 0;
CFileFind finder;
BOOL bWorking = finder.FindFile("*.*");
while (bWorking)
{
bWorking = finder.FindNextFile();
count ++
}
return count;
}

Oops.. You also need the names..
modify the function to return also the names using finder.GetFileName().
You can pass a pointer to a string array as argument and store the names in that.

Hello
Reply from Aman Sonny seems correct.
You can get the number of file in the varible count used by Aman.
To get the name of file excluding extention use finder.getFileTitle()
method.

Hello,
Here goes ur full solution.
int count = 0;
CFileFind finder;
CStringArray l_caryFileNames;
BOOL bWorking = finder.FindFile("*.*");
while (bWorking)
{
bWorking = finder.FindNextFile();
l_caryFileNames.Add(finder.GetFileTitle());
count ++;
}

Hi all,
I have a little dialog-based application that maintains information on paintings. On the dialog where I show/edit the information pertaining to an individual painting (like the filename of the painting's image, a title, a date etc) I would like to show a thumbnail of the image. These images can be either jpeg, bmp or gif files. Anyone have any suggestions on how to do this?
Thanks in advance
William
