A bug in the Microsoft ReportViewer control

I found a bug in the Microsoft Report Viewer 2005 control. When used in LocalMode in an application that does not have a strongName signature, the reportViewer control saves temporary files to IsolatedStorage folder and does not ever delete the temporary files that it creates. So the result of this is that it takes up a lot of harddrive space, about 240k per page of the report. And when a report has 900 pages, this is a problemo. The problem is solved simply by making sure that your application has a strong name key (see the “signing” tab of project properties).

 

Nevertheless, this untidy habit of not cleaning up after itself caused me a lot of problems, several customer servers where this application is installed almost ran out of hard drive space because of this bug. Not good!

We are suffering from the exact same problem. The Isolated Storage folder is filling up with gigabytes of data. Other than the obvious fix of signing our assemblies and deleting the isolated storage folder everytime a new report is generated, is there a way to circumvent the problem? I've searched quite a bit on the web and this is the only reference I've seen of this problem. Any feedback would be greatly appreciated.

How to Create and Run Tableau Bridge on Linux Containers

Tableau Bridge is now availble on Linux Containers. Yay! Now what does this mean and how do I build and run Linux Containers? We will discuss the advantages of running Bridge on Linux Containers the steps to build them, and finally, we will provide some automation script ideas for monitoring and scaling Linux Bridge agents. Tableau Bridge Today Until recently, Tableau Bridge was only available as a Windows application running on a Windows VM. It supported only one bridge agent per Virtual or Physical Machine. Advantages of Bridge in Containers Better Hardware Utilization: Linux containers are more efficient than Windows VMs, requiring only about 1/50th of the disk space. Ability to Spin Up Multiple Bridge Agents: With Linux Containers, it becomes easier to spin up multiple bridge agents on a single machine, improving scalability and resource utilization. Infrastructure Automation: Linux Containers enable easier automation of provisioning bridge agents and upgrading Tableau Bridge, the...

RAM Disks do not speed up Visual Studio

  The limiting factor for Visual Studio is disk IO. I got a tip to speed up Visual Studio from Channel 9 by creating a RAM disk which sounded like a great idea. However, when I ran a thorough set of tests, I found that the performance difference between the Ram disk and the hard disk were not appreciably different. This was a big surprise since RAM is 240,000 times faster than disk (see my previous blog post). But the reason is because Visual Studio and Vista do a lot of caching. So compile times for the same project in RAM disk and on hard disk were pretty similar. I also tested the time it took to search the entire solution for a word, and times to open a solution. There was no discernable difference!   If you still want to try it out and create your own RAM disk, you can download a simple RAMDISK.EXE utility to create a RAM disk in just a few minutes. What is a RAM Disk ?   Ramdisk is a virtual drive created in RAM.   Performance Analysis Creating f...

SpreadsheetGear vs. SyncFusion vs. ComponentOne

I conducted a three month analysis comparing three top spreadsheet controls for .NET application developers: SpreadsheetGear , SyncFusion Spreadsheet , and ComponentOne Spread.NET . The definite winner was SpreadsheetGear, with ComponentOne Spread.net in second. SpreadsheetGear provides the most Excel-like experience, is the most performant, and provides the most responsive and capable product support. I build a reporting engine for my company and SpreadsheetGear made it awesome. Our customers have been very pleased. I wanted to share my extensive analysis with any other developers out there trying to find the right spreadsheet control for their .NET application.   Comparison Spreadsheet gear grid goes to 1 million! Wow. (SyncFusion goes to 500 by default, ComponentOne goes to 60k) SpreadsheetGear is an older control which has been around for a while. It is built by the same guys who built Formula1, so they have been doing spreadsheets for many years. Sp...
