I sort of made a messed up program where half of it is in java and the other half is in C++.
So i plan to make a third program that would run the Jar file first then after that would run the C++ program.
Anyone know how and where i would start? I tired googling it but, my Jar isn't a application, i can only run it via command prompt which i'm not sure how to do in C++.
edit:I created a batch file to run the Jar. Currently trying to make a program that runs a batch file.
what platform are you running on? linux, windows, mac, etc
windows
Edit:I figured it out, thanks anyways
Edit2: how do i get a value from another program? I know how to make a txt file to transfer data if it use of/ifstreams, but i would like to know a easier way.
Shared memory. However, you have to realize that if it's going to work or not depends on what programming languages you intend to use it in. Sharing data between a Java program and a C++ program is going to be difficult.
Maybe I should just ask what you are intending to accomplish?
Just need to get the user input which is a simple one line string from the java application to the C++ application like filename and save location.
Java application reads a xml file and creates a sorted CSV, C++ application take this CSV file and split them up in to business groups on different CSV files.
You can avoid a temporary .txt file by using your batch file to "pipe" the output of the first program to the second program.Quote:

@Elkvis All the main funcation of the program is done. I don't really want to spend a few more days playing with XML.:frown:
@bernt hmm...so if i run a program with piping in C++, then the first input would be the one that i pipe through? eg. My GUI C++ program get a user input then calls a jar. Would my input go to the jar when it ask for user input or would there need to be a recieving function?
Alternatively I think clipboarding it would be an easy way too. However I would like try experiment with piping since it does seem pretty interesting.
Piping takes standard output (so in C++, the cout stream) from the first program and sends it to the second program's standard input (Java's System.in). Or when used with file paths, it will read from/write to the file depending on whether the file comes before or after the '|' symbol.Quote:
