hi Subbu,

In WTX menu, click on RULES --> New Function
It will disply Custom Function Modules windlow. There you give path (where to create function) and name of function then click Add button. It will display the Return and input parameter window. give required data and click ok. It will create a dll and .cpp files back end. You can use same funciton in WTX dev.

All the best!

Dear Vijji,

Thanks for the advice.

I have same issue, but for me, The files are generated with the name let say MyFunc.C

now when i modify the file, what should I do to be ble to use this function in the WTX?

What are the required steps?

 

If you can provide me with a sample scenario step-by-step, that would be perfect.

FYI, I am using WTX 8.4.1.3

 

Thanks and regards,

Alireza

The file that is created is a skeleton, and requires major modification in order to work.  Are you a C, C++ or C# programmer?

Thank-you.

Will create a file called WriteFile.c which I have renamed as before_WriteFile.c and attached.

Thank-you.

Then I edit that file (see after_WriteFile.c) and then use a C compiler to create WriteFile.dll.

This file is then placed into the 'function_libs' sub folder of my WTX installation, and then the following rule works:

=WriteFile->StringWrite("ABC")+"    "+LASTERRORCODE()+":"+LASTERRORMSG()

The result is that a fixed string 'Hello, world !!    :' is written back to my map.

I am not a C programmer, so this example is actually quite terrible, but good enough to demonstrate the process.

Thank-you.

Paul.

Dear Paul,

Thanks for your helps and supports.

I am also somehow new to WTX (ITX) and I am facing some kind of similar issue.

I need to create my own functions in C, I have followed the topic but I am facing error when I try to compile.

I even tried to compile the file shared above in TurboC++ for windows, and I face error as:

Undefined symbol _mpiMemMalloc in module...

Can you tell me what Compiler shall I used? Or what am I missnig which leads me to this error?

Thanks and appreciates in advanced.

It seems like either you have not got the TX SDK installed, or perhaps have not included the relevant libraries in the INCLUDE statement at compile/build time.

Thank-you.

Dear Paul,

Thanks for your reply and appreciate your time.

I think the issue is TX SDK as you have pointed to.

I will try and may be bothering you again.

 

Thanks
