Thanks for quick reply. However I can do that if my window app is in C#. When i use VB.NET I still have the same problem.

Hi Quan Nguyen,
Adding references to your application is straight forward and it does not matter whether it is a C# or VB.NET one. Can you clarify what you mean by "I can do that if my app is C#" - what is "that" in this context?

I created 2 test window app. 1 in C# and 1 in VB.NET. I added reference of the TestReport.dll to both apps successfully.
In the C# app, I was able to select the TestReport.Report1 under the "Report" property of ReportView.
However, in the VB.NET app, I can't even see that option listed in the "Report" property.
Thanks

Hi Quan Nguyen,
Your description of the problem has changed since your original post, where you stated that there is a problem setting a report to the Report property of the viewer programmatically. Now you talk about setting report through the designer. However since we were not able to reproduce such problem on our end (see attached screenshot), we kindly ask you to prepare a sample project (both class library and windows forms project) in VB.NET, that replicates this problem so we can investigate.
In the mean time, you can set the report property programmatically like in the original post, as long as you have added the correct references and it would work.
All the best,
Steve

Hi
In my original description, I did say this "After i referenced my test report project dll in my window app, i can't see it displayed on the report property dropdown list of the ReportViewer." I was refering to the design and did send a screenshot (untitled1.gif) of that. Anyway, my VS2005 VB.NET version might have prob. I will try this on another pc.
Thanks
