Shell, chain, run , I dont know

[Topito216]

Hello.

I have a program of mathematical adjust: "ajuste.exe".
In order to run it I have just to double click with mouse over the exe file. the program reads ascci data from file, calculate, shows result on screen and save results in a txt file. No problem, It works ok itself and I dont need to input nothing.

I want run it from a freebasic programa with chain comand.

Code: Select all

Chain ("C:/FreeBASIC/Proyectos/ajuste.exe")
sleep

Adjuste.exe starts but it dont read the input files that they are in the same directory that the executable.

I have tried exec comand but I dont know I need any arguments.

I cant understand what's failing with such easy command. I cant believe to find problems with that.

Best regards.

You could try:

Code: Select all

print Chain ("C:/FreeBASIC/Proyectos/ajuste.exe")
sleep

So you can see what Chain is returning.

I did it.

The adjust.exe starts but without data. Show errors and the number retourned in console is: -1073741819


Thanks.

I realized that if I double click over the main program bas (Chain ("C:/FreeBASIC/Proyectos/ajuste.exe"), it starts ok and works ok ajuste.exe. But it dont works if I compile and run the main program from FBedit that it's my IDE.
Thanks

Try:

Code: Select all

Dim path as String = Curdir
Chdir("C:/FreeBASIC/Proyectos")
Chain ("C:/FreeBASIC/Proyectos/ajuste.exe")
Chdir(path)
sleep

Thaks to both of you.

Now it works even from Fbedit.

I have learned one more thing.



Thanks.

Under FBedit, if you execute "Quick Run" at least once on a file.bas, the current directory is automatically changed to the directory of the file.bas.
Then, you can even "Compile" and "Run" the program, and the current directory remains set to the directory of the file.bas.

It is another method that my previous to change the current directory to the directory of the target file.bas.
