Hi, Even I have the same application. You can create an L5K file in VB and then import into your application. The L5K file is a simple text file and you can use streamwriter function. I have a sample code written in Visual basic 2005 to create a L5K file if you are intrested I can share it with you. There is a simple format that you have to follow to create these files. Please find attached the format file which I have created. If you use a stream writer function to create logic in similar fashion you can then import the project in LOGIX 5000 And if you have found other ways please let me know L5KFormat.xls
