• ComicSansMS Error when failing over to mirrored database

  I'm having a problem with SQL2005 Database mirroring. I have an ASP application that loops for a certain amount of interations and in each iteration I create a SQL Connection object and use the failover partner in the connection string. The object then writes a simple record and then the connection is closed and the process starts again. About half way through my loop I force a failover to the server mentioned as the failover partner in the connection string. At this point my application encounters a SQL Exception error and the application fails. I read in this article, http://msdn2.microsoft.com/en-us/library/ms366199.aspx , that this is expected and that you shoud request a new connection using the same connection string but ...Show All

• Zero_ viewing all memory objects

  Is there anything that will work simular to the watch, but list instead all objects existing in the current process (assuming debugger mode + PDB) You can use SOS and do a !dumpheap command, but there is going to be a lot of data coming back. There are some filters you can apply (object size, object type, generation) to reduce the amount of information. See Vance's post for getting started with SOS. For memory leaks you'll want to read this SOS post, too: http://blogs.msdn.com/ricom/archive/2004/12/10/279612.aspx I believe there are some other good tips if you google for SOS and memory leak. Thanks Scott! I knew there had to be a way. I have been trying to find memory leaks, and this looks to be the tool for the jo ...Show All

• OpinionatedGeek Fail to Load dll from C# when no VS2005 installed -'System.IO.FileNotFoundException'

  Hi, I am running C# application with a MFC dll on VS2005.

• YA say hello Mulitple .NET runtimes running at the same time

  If I have an exe build with v1.1 of the .NET runtime and it invokes a DLL built with v2.0 of the runtime, will multiple versions of the .NET runtime be running in that process I know I can override the default via an app config file. I was just wondering if a single process could be concurrently running multiple versions of the .NET runtime. thx in advance, todd I believe it was originally on the cards to allow different runtimes to be hosted in seperate app domains in the same process for .NET 3.0, but I think this has been dropped. It will probably happen some time but for now Nikhil is right, whichever runtime is loaded first is the one you're stuck with, and if you try and call a 2.0 ass ...Show All

• messaoud CoCreateInstance doesn't work if the InstallShield is installed

  Hi, I'm programming a DB access application using SQL Server 2005 OLE DB(Native client) provider. There's no problem everytime calling CoCreateInstance until I install the InstallShield program. After the InstallShield(Express edition) is installed in my pc, the result of calling CoCreateInstance() is strange. It seems that just return and I could not get the any error code. Anyone help There are occasionally interactions between InstallShield and Visual Studio, like this: http://support.installshield.com/kb/view.asp articleid=q106194 and maybe that's what you mean, but you need to be more specific.

• RayRay1039 SerialPort DataReceived Timeout?

  I'd like to get better control over when DataReceived are generated while using System.IO.Ports.SerialPort. In particular, I want to be able to control the timeout behavior. This can be done using SetCommTimeouts() when writing to the Win32 API but so far I have not found anything equivalent under .NET Anyone know how this might be done I was thinking I might be able to control it using IOCTL_SERIAL_SET_TIMEOUT but have not been able to find a way to access the underlying filehandle. Is there a way Hi, thanks for the reply. I agree that ReadTimeout applies to Read*() and not the DataReceived event. However what I want to be able to do is utilize the SetCommTimeouts functionality to control when DataRe ...Show All

• Erl Egestad How do I use one app.config across multiple projects in a solution?

  I have a solution with three projects - Common (which contains all the common business and data logic), Project A and Project B (their actual names don't matter). They all need to share the same app.config (in the Common project) but I can't work out how to do this in VS2005/.Net 2.0. Someone here ( http://www.dotnet247.com/247reference/msgs/56/284247.aspx ) suggested putting <appSettings file="common.config" /> in the app.config for Project A and Project B then adding a file called common.config to the Common project to which I move all the actual settings into. So I tried that but I still get no values when using the ConfigurationManager.AppSettings() call... it seems to me that Project A and Project B will have no id ...Show All
