how in debug mode watch the contents of the vector<> it only shows first elemnt only, and not tmp[i] telling it is not possible

int *pnData = new int[20];

pnData[0] //--> Will show first element
pnData[1] //--> Will show second element
pnData[2] //--> Will show third element....

<br />
pnData,20<br />

Another option is in the watch window, use

pnData,20

That will show 20 elements.

with best regards

csStringContent = "This is String"; // modify to "This is String" or replace a part of them
 
LPTSTR lpsz = csStringContent.GetBuffer();// modify lpsz
lpsz[0] = _T( 't' ); // This change will be reflected in the string. "<code>t</code>his is String"
 
csStringContent.ReleaseBuffer(); // You should call this after GetBuffer

csStringContent = "This is String"; // modify to "This is String" or replace a part of them
 
LPCTSTR lpszC = csStringContent;// modify lpszC
LPTSTR lpsz[0] = const_cast< LPTSTR >( lpsz ); // Remove const'ness from string, not a good idea and should be avoided.
lpsz[0] = _T( 't' ); // This change will be reflected in the string. "<code>t</code>his is String"

TCHAR str[100] = "This is a string";<br />
_tcscpy(str[2], "aaa";<br />
CString cstr = str;

Your second method is just plain evil - although you mentioned it sould be avoided I'd go as for as to say you shouldn't have even mentioned it as an option. Even if it works on one MFC verion it may stop working in a later version.
