Do a search for 'C# vista manifest' for more information. It's not always needed for every application, I think it is dependent on what the application actually does as to if you need one or not. Not 100% thou Life goes very fast. Tomorrow, today is already yesterday. Byte[] Splitting in c# GauravKP6-Jul-09 1:30 GauravKP 6-Jul-09 1:30  HELLO....... I want to split a byte[].....

'Red Cross' is displayed for non-admin user Sifar - 06-Jul-09 0:31 Sifar - 0 6-Jul-09 0:31  Hi All, I am re-posting this question with some more detail. In my windows application I am using 'Zedgraph' dll for displaying graph. In my code I am not using multithreading anywhere. On some of the systems (Windows XP) it shows unhandled exception 'System.InvalidOperationException' (object is currently in use elsewhere). And the instead of graph it just shows RED CROSS. At client side network, if the user is an Administrator then the application runs fine. But if the user is not an Administrator then after few seconds above error is being observed. That means non-admin user can view the graph only for few seconds during starting of the application. Any idea... I have googled about this issue but I found that it may be due to Multithreading and I am not using it anywhere. Any suggestion would be helpful... Regards, -SIFAR. Re: 'Red Cross' is displayed for non-admin user Hariharan.T6-Jul-09 0:58 Hariharan.T 6-Jul-09 0:58  Check the event viewer for any permission errors as you mentioned the administrators doesnt have any issues in viewing the graph... Hariharan.T Re: 'Red Cross' is displayed for non-admin user Sifar - 06-Jul-09 1:02 Sifar - 0 6-Jul-09 1:02  Thanks Hariharan, But a non-admin user can view the graph for few seconds when the application starts. After that the 'Red Cross' appears... Regards, -SIFAR.

Re: how can i avoid this error while working on c# form application?? Dinesh Mani5-Jul-09 23:56 Dinesh Mani 5-Jul-09 23:56  This generally happens when you make changes to your code when the application is running in debug mode. Since the code has been modified, VS block access to the pdb file and you get a access denied to the .pdb file. You have the following solutions to this problem 1. As Hariharan had said, do a Rebuild of the solution. This in most cases clears the lock on the pdb file. 2. Locate the pdb file using the windows explorer and delete it and then try build/rebuild from the VS. If you get file is being used error, check if there are any process that are using this file still running using the task manager / process explorer and kill it and re-try. 3. Do a build/rebuild of the solution in "Release" mode and then do a build in "Debug" mode. Not sure if this would work for C# Win Forms, I've done this only on my Web apps. Re: how can i avoid this error while working on c# form application?? ScottM16-Jul-09 6:51 ScottM1 6-Jul-09 6:51  I had this same problem with Windows 7 beta, the problem was intermittent and I'm not sure what was causing it. Do you run Visual Studio as administrator? The problem seems to have been solved since Windows 7 release candidate. Re: how can i avoid this error while working on c# form application??

It internally has some calls to custom interop. I dont have any problem in executing it manually by either double clicking the exe or thru command prompt, everything works as expected. But the moment i launch it using windows scheduled task it always fails. Is this a know problem with interop calls, when an executable runs thru scheduled task? it fails at the point where i make a method call on the interop object. BTW i am using W2K. Any suggestion/solution? Thanks in advance.... Hariharan.T
