Hello NG,
After a bit of a wait my bookstore, SoftPro of Waltham, MA, got in the Brian
Bischof book: Crystal Reports .NET Programming. I have read a few books on
CR, but I am very new to it, C#, and SQL. The book is excellent.
Undaunted, I have plowed into a conversion of my old COBOL ERP system,
MCS-3, into C#. I have quite a bit of Inventory Control done and working.
For reports I am trying to use CR. I have a half a dozen of them working
directly off of the SQL Server database. In order to do record (OK, I am an
old COBOL hand! Read row.) selection I have a field (OK, column) called
im_planner_code in the database. Using the default parameter ?plannerCode I
am able to select all rows with im_planner_code = "A". I would like to
develop my own parameter dialog box. To start I have invoked the code
listed below at the load event of Form1303. It compiles clean, but has an
execution error at the highlighted line. I would of course like to know
what my problem is, but beyond that I need to know how to debug CR execution
errors.
Is there a good newsgroup for CR under .NET? I currently read:
Microsoft.public.dotnet.languages.csharp. Thank you in advance.
Cheers,
Bob
