Converting PB 9 classic app to .Net winform

Question

I have a powerbuilder 9 app and we are converting that to .net. To do this, I am following the below approach :

1. Convert powerbuilder 9 app to powerbuilder classic 12.5. - Completed successfully.
2. Convert powerbuilder classic 12.5 app to powerbuilder.net 12.5 app. - In progress, with build errors.
3. Create .Net dlls in pb.net 12.5
4. Refer pb.net 12.5 dlls in .Net winforms project to reuse the existing forms and the code. - Pending.

In step 2, I am facing issues for building the app successfully.

After conversion, I got the below errors :

1. There is a functionality to create excel sheet. After conversion, there is an error at the below line.

   • workbook.Sheets(1).CELLS[1,8].columnwidth=9
   • Error C0014: Undefined variable: columnwidth

2. There is an error at GOTO statement.

   • Syntax/statement in the code: GOTO IssuerLtrsOnly1, IssuerLtrsOnly1:
   • Error: No label 'IssuerLtrsOnly1' within the scope of the GoTo statement.

I commented the above lines to see the successful build. Unfortunately, below is the error i got again and with this error I am unable to find the location of the error. On double click of the error, it is not pointing to the error location after target corecompile.

Below is the build information:

PowerScript compile complete -- 0 error(s), 92 warning(s) MSBuild started... output path: C:\Data\DUTCH\PB 12.5\Copy of DAU_PB_CODE_dot net 12.5\wpf\auction.out\bin\Debug Project "auction.csproj" (default targets):
