What do i need to do to open a DotNet Crystal Report developed in a Visual Studio 2017 environment in a Visual Studio 2019 Community edition environment.

This problem is a Crystal Report Problem. And the environment is CrystalReport for DotNet running in c# environment

I had Visual Studio 2017 installed at a time and did my Crystal

Reports in that environment.

My CrystalReport.rpt and The form that drives it are part of my report project.

To open an existing report for further modification I simply double click the .rpt

file and it opens for modification..

I have now upgraded my Visual Studio to 2019 Community edition

Each time i now double click a .rpt file it opens as a set of characters which have no meaning.(See below The characters). And this is true for ALL my reports.

When I run the report I still get the regular out put . For instance for above the report header is shown below

Any help will be appreciated

Thanks

which SP for CR are you at? Install the latest version of CR Developer Edition. Have a look at https://www.tektutorialshub.com/crystal-reports/download-crystal-reports-for-visual-studio-2019/

I have downloaded and installed CrystalReport 13 SP30 which appears to be latest release.
Now my reports open BUT during execution they all cancel at the same point of passing the
dataset to CrystalReport. (See Screen Below)

Is there a particular adjustment i need to do to my report as they all stop running at this point ?

Thanks

Looks like the datasource is not what is expected by the report.
Were you running a very old version before updating to SP30?
What is the Inner exception?
from within the CR designer, can you "verify database" to be sure your definitions are still in there?

Can not really remember the version i was running. But it is compatible
with VS2017 I think is was SP25

Having said that I have now run Verify Database with the error below

So what do you suggest to fix this problem

you need to modify your app.config file as shown in https://refat38.wordpress.com/2011/12/20/crvs2010-crdb_adoplus-dll-not-found/

Not sure why its not working.

I attached the AppConfig File modified

The Exception and inner Exception

The Exception Unhandled and the Inner Exception are is the same error box.
I just could not print them together.

What am i Doing wrong

in your solution, do you just have a single project or do you have more then 1? maybe your report is in a class module! The adjustments to the app.config needs to be done in the executable project.
