How to add 2 project together for compile and make as one.

Under the same workspace, there are 2 projects A and B. Currently, we compile A and B separately. Run A first, A dumps its result to a file in hard disk. Then, run B and B get input from a file from hard disk(this file is either the one porject A created or from somewhere else.)
 
Now, want to compile and run these 2 projects together following any of the following sequences.
 
1. Compile A & B together, then automatically run A, then B (A created a file in hard disk and B get input from the file A created)
2. Compile A & B together, then run B only (input from a file with known file name from hard disk).
 
A command line parameter is used to choose any of the above 2 running sequences.
 
Do I need to merge the 2 projects together? (it is very big, a lot of files involved, there are a lot of variables to be renamed since the same names appear in both projects,will cost a lot of time)
 
Any easy way?
Thanks

Keep them as separate projects and create batch files to do the processing that you require.

eg. batch file - RunB.bat

x:\SomePath\Release\B.exe "PathToFile.txt"


To compile a project - CompileB.bat

devenv x:\SomePath\B.sln /build "Release"

you may also write small program code to perform this 'Automation'..if you need to programatically detect if text file is ready or not....

You may use SHellExecute() / CreateProcess() for your purpose to execute command lever compiler options..

1) Compile and execute 'A' with ShellExecute()

2) wait in loop for creation of text file ( e.g by detecting if file is ready to open in read mode..)

3) Compile and Run B by taking input from generated text file.

You may refer samples how to use ShellExecute :

<how to detect whether the txt file is ready in batch file.>

When 'A' finishes writing the text file then it could start 'B' (eg. by CreateProcess) - no need for another app in that case.
