Merging different files into one big file

[gunnar66]

Hi I want to merge several files into one file. How can i do this in Visual C++ In DOS it is very easy, you just use the copy function in a batch file, e.g copy "c:\tstTag3.csv" + "c:\tstTag4.csv" "c:\test.HTML" Can anyone help me get started with this? Thanks Gunnar

You use the file commands: CreateFile, ReadFile, WriteFile, and CloseHandle functions. The first call creates the output file and opens the first input file. When you are done reading the first input file, close its handle and open the next one. Open each subsequent input file for reading and keep writing to the output file. Close the output file when you are done reading the input files.
