Calling Application using Process

Question

I am filling a DataGridView in a Window's database application. It is working fine.
Now I want to run this application from another application. For that I am using process class in C#.

When I run the application directly it is working fine but When I call it from another application it shows an error like this:

System.Data.OleDb.OleDbException:No value given for one or more required parameters.

Error is thrown by ExecuteCommandTextForSignleResult class of Framework

Has anyone faced this issue before?

Could you show us a bit of code? Particularly the (suspected) errorprovoking statement.

Solution 1

I assume your connectionstring is in an app.config file.

Could it be a missing configuration file (<yourapp>.exe.config)?
Is the path to all required files defined?

Cheers

Hi,

What i guess that you are passing some parameter to fetch data from database. So you are using process.start for your application to run then pass those parameter and collect in the main function of program as string array.

To get exact solution please post the code to get data form database.
