• .NET Development .NET 1.1 vs .NET 2.0 behaviour with Image fields

  In not .NET 1.1 and 2.0 the System.Type mapping for a SqlDbType of Image is byte[]. If you use this type to create a SqlParameter (with a value of DBNull.Value) and then use this in a SQL statement of the form "Update table Set ImageField = @parm where ......" Then in .NET 1.1 it works, but in 2.0 you get an Exception "nvarchar is incompatible with image" How can you determine the correct System.Type to use for Image fields, and why is the behaviour now different The application code is generic and not tied to specific database designs. Thanks Tony OK, here goes. We have a generic Messaging application designed to acceps XML messages from varying clien ...Show All

• Windows Forms SplitContainer Panel MinSize Defect?

  I have a vertical split SplitContainer inside the top panel of a horizontal split SplitContainer and am trying to set the panel2 min size for it. I'm getting the following designer error: SplitterDistance must be between Panel1MinSize and Width - Panel2MinSize. This is somewhat confusing first of all, since the change was made in the designer. In the first instance therefore, I'm assuming this is a bug in the designer. The logic of the error message is that SplitterDistance should be between 0 and 560 minus 243 i.e. 317 which at 311 it is. Has anyone else come across this or have a workaround // // splitContainer2 // this .splitContainer2.Dock = System.Windows.Forms. DockStyle .Fill; this .splitC ...Show All

• Windows Live Developer Forums MapCruncher customer tile layer looks a little MapBlended ...

  I tried making my own custom tile layer using MapCruncher and it looks very good when I view it using the samplepage.html that comes with MapCruncher. However, when I tried to use my own html page by modifying the custom tile layer code in the sdk it looks a little blended. Does any one know why this is happening I made the following modifications to the custom tile layer sample code: function GetMap() { map = new VEMap('myMap'); Changed the default Lat Long to centre where my custom layer is. map.LoadMap(new VELatLong(43.7706272357647,-79.5549744612714),11,'r' ,false); GetTiles(); } function GetTiles() { Modified boundary box to be in the general location of the map var bounds = [new VELatLo ...Show All

• Visual Studio Moving VSS6 from one server to another - howto, plus bonus questions

  Hello, We are currently running VSS 6.0a on an old piece of hardware running WinNT. That server is going away. We have a newer server running Win2003 Std. that will host VSS moving forward. I need to migrate our existing VSS over to it. I am by no means a VSS expert - mostly just a user, but now with Admin rights (this got dumped on me). Also, our office is closing next year, so I really don't see the need to upgrade to the newest version of VSS and deal with users not understanding this or that on the interface, or getting upset about the GUI changes. We'd really just rather move the data off of NT and onto Win2003, and let the company decide later if they want to upgrade VSS versions or move to different source control software. ...Show All

• Windows Forms Unhandled Exception in NumericUpDown Event Handler

  The NumericUpDown control throws a NullReferenceException if Application.DoEvents() is called in the ValueChanged event with some additional processing and the up or down button is pressed rapidly. The exception can also occur if the event handler takes a while to return. To reproduce, add an event handler for the ValueChanged event on a NumericUpDown and insert the following code into the event handler: for(int i = 0; i < 10; i++) { Application.DoEvents(); Thread.Sleep(50); } Run the project and hold the up or down arrow for a few seconds. The following exception occurs: System.NullReferenceException: Object reference not set to an instance of an object. at System.Windows.Forms.UpDownBase.UpDownButtons.TimerHandler(Object source, ...Show All
