When I attempt to compile the following: ----------------------------------------------------------- #include "stdafx.h" ... ----------------------------------------------------------- it returns "fatal error C1083: Cannot open include file: 'stdafx.h': No such file or directory".

• Visual C++ int CString::find() ignores newline character?

  I have a text file that is of this format: abc def ghi I read this file into a character array and then passed it into a CString. When i did a find on the CString ( CString.find("def") ), instead of returning me value of 4, I get a value of 3. When i did CString.find("ghi"), i get 6 instead of 8. That made me believe CString::find() ignores newline chars when counting for the index. Is this true If it is, is there anyway I can make it include the newline chars in the count Would appreciate any insight on this. Thanks in advance! Thanks alot ppl, yup you guys are right, CString::find() works properly, af ...Show All

• SQL Server Hows does SSIS improve concurrency without loacking

  Now, DTS runtime uses multiple threads for execution to improve concurrency, performance and scalability. In order to avoid having more than one thread attempt to access the same variable at the same time, all access to variables must be made "safe" by locking them for your operation. How does SSIS fare on this count IS does this with the VariableDispenser object. It's exposed in the script component and task. It essentially locks variables for you. ...Show All
