Brief Information about the April '06 CSIG Meeting

File Copy to Folder Utility - CoreFold.exe

VC++ 6 Compiler

B. Arnold

Welcome to the CSIG, a Special Interest Group of the ACGNJ. The subject for this month is a discussion about MFC Windows Programming using Microsoft Visual C++ version 6.0.

At the meeting, we are going to discuss a file copy program. Here's the background: I like to keep my VC6 C++ completed executable files in a "Core" folder so that they are easy to find and run. This month's program is called "CoreFold" and the compiler will create it as "C:\Program Files\Microsoft Visual Studio\Projects\Corefold\Release\corefold.exe". My "Core" folder is "H:\Core", and I usually use Windows Explorer to copy the file. Keeping 50-100 different projects up to date in this manner has become quite tedious and takes about a minute per project to copy the executable.

Therefore, here is the strategy. Build a list of potential source files and copy the newer files to the core folder. The manual operation which previously could take over an hour now takes less than a minute with this automated file scan and copy. To accomplish this, the program will require the following:

In addition to the above requirements, let's add some Bells and Whistles:

The beginning of the evening (starting at 7:30pm) will be a RANDOM ACCESS discussion. The main presentation will present the program.

As always, the download site has code and programs from our meetings. ( Source Code Files )
