Graph not displaying in VB6 application

[guhanath]

Hi,

One of the client have legacy VB application(vb6) which incorporated crystal reports v8.xxx. The dev machine is Vista 32 bit and the deployment/setup installation was done in Win 7(64 bit).

The application and the reports are working fine as expected. However only the graphs/charts are not displaying.I have verified that all required Crystal reports dll are there (crviewer.dll, craxrdt.dll, craxddt.dll) and been registered. But the graphs are not displaying. Anything is missing from my side? because no error reported from the application as well.

Thanks
Guhan

HI All,

Thanks

Also we just compared the original files present in the current prod location and we could see some files are missing at the dev environment.SOme critically noticed are oledb32.dll, scrrun.dll, crviewer.oca(but registering this in Win 7 gives compatibility error), rdocurs.dll.

Not sure if any of these DLL have relation to crystal graphs/reports. So if anyone have suggestions share your thoughts

Is you select the Crystal Reports Chart Viewer?

Hi,
Only the dev machine have crystal reports software installed but the deployment machine contains only the crystal reports runtime files.
Following files are available and registered iin deployment machine
1. crviewer.dll
2. craxdrt.dll
3. craxddt.dll

Not sure if the below dlls are necessary for the chart to work
oledb32.dll(registration of this dll hangs the setup file so have excluded in the Listing File in the setup/installation)
crviewer.oca(registering this gives compatibility issue in 64 bit machine(deployment machine)
PG32CONV.DLL
msbind.dll
msdatrep.dll
mdac_typ.exe

Any suggestions would be helpful. Also any idea what is the dll for crystal reports chart viewer control?
