Ramil,

Did you try COM EXE instead?

>I have a Session class that instantiates a ReportListener object. The ReportListener object uses the _GDIPlus.vcx to print rectangles on the Page Footer band of a report. Basically, the intent of the report is to plot a production run schedule using a rectangle for each production run. The report layout has the hours (6 AM to 6 AM) for 24 hours on the left side, top to bottom. The days of week (Monday to Friday) go from left to right.

>My problem is that the report output is not properly rendered when ran as a DLL. The problem is that when the Render() method is called, the parameters are not correctly passed by the ReportListener object.

>1. Create the VFP9 project: Name the project as AvailReport and add these files:
>1.1 ProductionRun.prg (Set Main)
>1.2 ProductionRuns.Fr* (in Document)
>1.3 _GdiPlus.vc* (in Classes) - Not attached. You can find these in the VFP9 folder.
>1.4 *.H (2 files in Text Files)
>
>2. Copy the AvailTest.dbf/fpt into the same folder.
>
>3. Set default to current folder and Run in VFP9, ProductionRun.prg (Observe the proper behavior of the report). Also, take note of the Top,Left numbers in the Prod Run of the debug text that will come up after you close the report.
>
>4. Compile as Single-Threaded DLL. MTDLL is not allowed.
>
>Test the DLL
>1. Run the TestReport.prg from VFP8 or VFP9. There will be no preview and the report is directly outputed to the printer. Take note of the Top,Left numbers in the debug text after the report is printed. You will see that all the values are Left:8488 Top:8488.
