This is only possible if states of the program is static and do not change at run-time.

Thanks Sandip
I think that's exactly what i'll do. In fact I already do this and have several menus for different situations. However I think I got so focused on trying to correct the problem that I did not think to apply this practice again!

Hi,
I`m somewhat new to programming and I just have a question about strings.
Say I have a string that is read from a .csv file and looks like
word1,word2,word3,word4
how would I isolate, say, word3, and have the value in a seperate variable.
Any help in working with .csv in C++ would be great as well. I`ve only figured out how to extract rows from the file using streams. However, as my question states, I still have trouble with columns being seperated by commas and how to perform operations on them. Any help would be appreciated, thanks.

You can use CString::Tokenize() method to get values separated by any separater like comma, space etc.
See the example from MSDN:
Example
The following example demonstrates the use of CStringT::Tokenize.
CAtlString str( "%First Second#Third" );
CAtlString resToken;
int curPos= 0;
resToken= str.Tokenize("% #",curPos);
while (resToken != "")
{
printf("Resulting token: %s\n", resToken);
resToken= str.Tokenize("% #",curPos);
};
Output
Resulting Token: First
Resulting Token: Second
Resulting Token: Third

You need to tokenize this string based on a separator char (for you it will be ',').
You can use either Tokenize function of CString or _tcstok_s. Then you can do additional operations based on the tokens, like compare and decide whether it's the string that you were looking for.

CString's Tokenize method helps
Somethings seem HARD to do, until we know how to do them.

can you give me a sample code please

It is a simple function, takes no parameters and returns TRUE if the user is an Administrator or FALSE if not.
if(IsUserAnAdmin())
AfxMessageBox(_T("User is an administrator"))
else
AfxMessageBox(_T("User is not an administrator"))

You need sample code for using a function that takes no arguments and returns a simple type.  Are you really a senior developer?

You can use CheckTokenMembership. Here is the link to this in MSDN -> http://msdn.microsoft.com/en-us/library/aa376389(VS.85).aspx[^]
Source for IsUserAdmin is shown here, you can customize it for your needs.

MSDN says that you'll need to link to shell32.lib and #include <shlobj.h> to use this function.

Probably your SDK is too old. See question no. 2.2 in this FAQ article[^]

Hi friend,
I am using this code in my system to identify What is computer name & currently who is using it.
<code>/////////////////////////////////////////////////////////////////////

// Get and display the name of the computer.

::MessageBox(0,"GetComputerName","Cannot computer name",0);
s.Format("%s", infoBuf );
::MessageBox(0,s,"Computer Name",0);
// Get and display the user name.
bufCharCount = INFO_BUFFER_SIZE;
if( !GetUserName( infoBuf, &bufCharCount ) )
::MessageBox(0,"GetUserName","Can not read user name",0);

}
I have add this function to find User account type but i got following error
CheckTokenMembership' : undeclared identifier

Hello...
The function CheckTokenMembership() requires following things :
Header : Declared in Winbase.h; include Windows.h.
Library : Use Advapi32.lib.
DLL : Requires Advapi32.dll
Check by including this header file.
Next solution is you can you something like :
Bool IsUserAdmin(VOID)
{
DWORD i;
TCHAR infoBuf[INFO_BUFFER_SIZE];
DWORD bufCharCount = INFO_BUFFER_SIZE;
char admin[]="Admin"
Have Best Luck this time...
