Processing Extension written in C# or VB.Net

[wibgiwlst]

I am being forced to write a processing extention. I have spent quite a bit of time with tech support and we are convinced of the need. I have downloaded the C++ example and I am a bit confused on how to convert it to the current object model. Also, I need access to the code so using APOS's solution doesn't work. Does anyone have a processing extension written in C# or VB.Net code that I could use?

Pretty please with sugar on it!

Hi,

I have written lots of PE's.

First of all I am not aware of any .Net related API's available. Since it is DLL, you can code and test using VC++ (I use VC++) and call that PE from the application.

Post more specifics if this does not answer your questions.

Do you have any source code you would consider sharing?

What issues have you run into with writing your own PE?

What advice would you pass on to someone just starting?

Hi,

Sorry, unfortunately I can not share any code. I use to work for Solution Partner of Crystal Decisions and I have kind of NDA signed with them.

When I started writing PE 2 years back, I struggled a lot with lots of problem. Biggest problem was not flushing the text properly, I was using for troubleshooting.

2nd biggest problem I ran into was; PE used to work fine couple of times but there will be memory leaks if you don't carefully delete the pointers and PE will hang. ONly way to start that was restart the services or restart the computer.

So, to start you have to be a Average C++ programmer and understand the use of Pointers in details, Allocating / De-allocating memory locations too.

Hope this helps and I would be happy to answer your specific questions to get you started.

Thanks,

V
