Re: run a exe file by java code
 
If its a Windows system where the Java application runs, use this

Code: Java
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
// url is the URL u want to open

Thank you very much for ur help. I like to use applications programatically. for an example I have to open a word file and draw a line programatically. Can I do this task by java or any programming language?

Re: run a exe file by java code
 
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "C:\\sample.exe");
using this code I have open an exe file from java....

Now I want to open the same exe by passing two parameters....open a C source code and a file to redirect the output....

How can I do that?
