C# - App Hosting Report Viewer Crashes On Exit After Export?
Apr 21, 2010
We have a .NET Winforms application that hosts the Crystal Reports Viewer control (Version XI). It works well for the most part but when an export of data from the viewer is performed the application will crash on exit and in unmanaged code. The error message is not very useful and just says that an incorrect memory location was accessed. No other info such a specific DLL etc. is provided.
This only happens after the viewer is used to export a report to CSV, XML etc. My guess is that at some point in the export process Crystal creates a resource that attempts an action on shut down to a parent window (perhaps) that no longer exists.I've seen a number of memory leak and shut down issues with Crystal but this one's new. Has anyone seen it and come up with a workaround or has ideas for workarounds?So far we've tried explicitly disposing of all crystal-related objects, setting to null and even setting a Thread.Sleep cycle on shut down to "give Crystal time to clean up."
Update:The crash happens only on shut down (so not immediate)All export formats work
All export files are created properly
CR is installed on the same machine as the hosting .NET app not sure about exporting from the IDE... is that even possible?

I have a strange issue with a Web Browser control on a form. The application I made is nothing more than a form with a tab container and each tab navigates to an intranet web page. One of the tabs is directed to a documentation site that allows users to view machine documentation (parts lists, PDF files, electrical/hydraulic prints, etc.). Everything works fine on XP, but on 7, the application crashes when trying to view electrical prints (DWF files). If the site is opened in internet explorer, the DWF files open as intended. The computers have the Autodesk DWF viewer plugin installed (V 6.0). I need to somehow direct my application to the DWF plugin?

in my app, I want to use reports. It's a long time ago, when I created my first report and that was in vb6. Now, I would like to use the report viewer control and the reports, created in vb.net. I use postgresql database with an ado.net connector (also I have dataadapters, datasets, datareaders, etc). I created a form and placed a report viewer on it and I added to my project the first empty report too.

I created a report using report wizard. I placed the report in ReportViewer1. I Have a button that searches a particular query and returns the result to the report-viewer table. But the problem is, each time i click on the button, the old data in the ReportViewer1 table doesn't get cleared for the new query result to come in. All it does is append the new results to the old.

I have a ReportViewer control that the users can export to excel, and I'm looking to prevent the Excel Export error if a report is over 65536 rows rather than catch them after they occur. I am having trouble finding the row count that would be exported, does anyone know how this might be done?

I have a "MicrosoftReportViewer" on a form and a Combo box that lists the available reports (which will end up being dynamic in the end).
When the use selects an item from the list, the system loads up the correct report (populating any datasets needed) and then displaying it.Thing is, I can't get the viewer to change the displayed report, it just refreshes the first loaded report.
As you can see from the code below, there are two reports set up. I can get either one to be displayed if you select it first, sadly you're then stuck with that one!Currently they both use the same datasouce, so no need to mess about with that.
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Me.viw_ShowAllRepairsTableAdapter.Fill(Me.RepairsSystemDataSet.viw_ShowAllRepairs)
[code]....
This just loads up the report that the viewer has set as the default, reguardless of the report selected!What am I missing? There should be a way to change the report being viewed and I don't really want to be having multiple viewers just to house multiple reports?

Havent done this yet, trying to figure it out, I have been reading different post concerning temp tables to use with a report viewer and have been left confused. I have 2 tables that I would like to combine certain columns with to use in a report viewer.
I can itenerate through each table to retrieve what I am wanting, but how do you create a temp table to use in a report viewer? Will this table use an adapter and binding source?

Hello,
I have a web app and I have a report viewer in my app and it works fine in VS 2010. Once I publish and move it to my server I have issues. The report viewer is grayed out (please see the screen shot report_error.png). I am using Windows Server 2008 R2 and IIS 7.5. I am running it on integrated managed pipeline and the 4.0 framework. I have been digging for several hours on Handler Mappings and Config Files. I have added the Handle Mappings. According to all other forums this is the way to fix it, but it still doesn't work. Any suggestions?
Here is my Config File:
