• .NET Development .NET remoting and local web server

  We have a backend application and ASP.NET web application running on customers' sites. Once in a few weeks they would report that they could not run our web application. They get the "Cannot find server" error on the browser. If they try to go to  http://localhost/   they will get  the same error.  The ASP.NET application communicates with the backend application through .NET Remoting.   To fix it, they would have to kill the backend application and restart it. Then the web app would come up just fine.   What could be the problem in the backend app that caused the local web server down Any help would be greatly appreciated. hong2007     ...Show All

• SQL Server Conditional SQL Insert Query

  I have a simple ms access table with no primary key. I want to check if the value exists before it exists. I know there is way to do that directly using a insert clause without having a select statement but cannot seem to get it right. Any help would be greatly appreciated. Regards, Vibhu Bansal.

• Windows Forms DataGridView and Images

  I have a DataGridView myGrid; I set myGrid.DataSource to a DataView that has a column called Type.  Column Type is a string in the DataView, after I set myGrid.DataSource to the DataView I would like to change myGrid.Columns["Type"] to a bitmap. I have tried the following code but instead of the picture, the cell contains the string value "System.Drawing.Bitmap" (without the quotes). private void myGridCellFormatting ( object sender , System .

• Game Technologies: DirectX, XNA, XACT, etc. BoundingBox for Models

  Hi, I'm very much used to using Geometry.ComputeBoundingBox() from MDX 1.1 and am wondering where the equivalent in XNA is. My problem at the moment is that my models are having their centres placed at Y coordinate 0, so half is above ground and half is below ground. My solution has always been to compute the bounding box and simply raise the mesh by the amount that the min vertex is below the ground. (So minVertex.Y = 0). The BoundingBox has a constructor that takes a List of Vector3s, but this would presumably mean iterating over every ModelMesh in a Model, reading out the Vertex data from the VertexBuffer and extracting the x,y,z values for each vertex... this seems rather long winded I've seen a lot of people talking about ...Show All

• Visual C# Automatically install and start service

  All the help stuff I have read, mentions using the command line InstallUtil.exe to do a service installation, followed by a manual start. Is it possible to have the service exe itself do the install and start-up to make distribution and handling a bit easier for non-techies (after all, users are used to just double clicking an exe file to have an app run, and it would be good to have the same functionality with a service.) Russ, You may certainly do that. Your other option, which I mentioned - but have never tried, is to load your very own service assembly from your very own executable, and try and call the Install() method on the ServiceInstaller derived class. My wrox bible indicates that installutil merely does that anywa ...Show All

• SQL Server Script component with multiple outputs

  Hi, I wonder if someone might be able to help me with scripting a script component. I'd like to include error redirection of rows within my script. If the conversion of any of my inputs fail i'd like to catch the error and then just output all values to another output path. The output path will just take the input values without converting them from string data types and output them to an error table. In the script i imagine i would use try catch statements and if it fails then set the output. I am not entirely sue as to how to go about switching between outputs though. Any help on this matter would be greatfully recieved. Cheers, Grant Here is some additional good links: http://msdn2.microsoft.com/en-u ...Show All

• Visual FoxPro Will VFP6 work with Windows Vista

Can VFP6 work in the Windows Vista environment How can this problem be overcome Many thanks in anticipation. > And in my opinion the point is:  if I have an application VFP6 (and perhaps I don't possess the sources, or I don't have resources to convert the application to new versions), in some way I have to be able to make it work.
