Multithread multithreaded program

Question

Any way of doing this? I have this multithreaded java app I'm scraping, and it doesn't behave well when number of threads are more than one. Cheers!

Yeah, I think we need to know more about the other applications. Can you get the other applications to do what you need them to do without executing them from C#? If so, then we need to figure out how to do the same thing, except from C#.

You know what? I agree 100% with you, and I wouldn't normally do it that way myself. My only defense is that my temperature is now 39.5/103 degrees (and coming down), and my body told me to get the ... to bed. That's why I stopped researching myself, and that is also why I was a little bit brief ;) Anyway - what I'm trying to do is create a shell to automate some of the manual tasks creating some output files I need. In order to do that, I first need to run the java application to generate the base files and get some info out of the text printed to the screen. I then need to run a windows forms application to modify these, and lastly I need to run through the files doing some search and replace. I have no control over the source files of the first two apps. Where I'm at: My test application is seemingly working just fine, except the java application is a little bit dodgy and...just hangs. I have no idea why, and there's no useful information in the logs it provides. When I turn the number of threads down to 1 in the config, it's seemingly working fine, but it's dead slow. That's why I was wondering if there's any trick to run a multi-threaded application from a thread (actually, when I'm done testing I will be running at least 5 threads in parallell). I spent like 6 hours working on this yesterday, so even though this is my first real attempt at threading in C#, I do believe I've invested enough time in this to try to involve the experts (that would be you guys :D ) Hopefully, this explanation was better. If not, I have to wait until my fever breaks and hopefully I'll be more coherent then ;) Cheers! Now where's my cough syrup...

First, I think it is best to not rely on the subject to ask the question. For one thing, I often open more than one thread at a time, so when I read the body of a message, I might not see the subject. Also, in my experience, when someone uses the subject to ask a question or part of a question, it is nearly always necessary to ask for clarification. People that use the subject to ask a question do not invest the time needed to get a good answer. I sure don't understand what you are asking. I don't undersand "multithread a multithreaded program". I don't understand what you mean by scraping, and I wrote the article called Introduction to Web Site Scraping . Also, when saying things such as "doesn't work" or "hangs", it is ususlly necesary to be more specific. Hopefully someone else will understand and can help.

As the title says - multithread a multithreaded program. The java application I'm scraping hangs if it uses the built-in threading support, but works fine if I limit the number of threads to one per instance. I was wondering if this is some special case I should be able to work around with some magic.
