• .NET Development Serialization framework improvements in .Net 2.0?

  I have re-implemented an IFormatter for the project NGrid . The code can be seen on this page . I have found such tasks very tedious with the current design of the serialization framework in .Net 1.1. Here below, the list of the hard points. IMessage serialization (and the derived classes) is pure hell. As the consequence even the BinaryFormatter fails when it tries to serialize an IMessage containing itself an other IMessage. IMO, the IRemotingFormatter interface is useless, I see no reason (especially performance) that implies such an hacky design. Cf IBinarySerializable interface as a solution. IMO, the Formatter class designed that ...Show All

• Windows Forms DataGridView and the automatic ellipsis

  I am working on converting a project from VS3 to VS5. One form has a grid which now uses the new DataGridView. Overall it is great. However, there is one small issue: When the amount of data in a cell is larger than can be displayed, an ellipsis is shown. This normally would be fine. However, this grid displays records from a database and a field may be 30 characters long, but with only 5 actual characters and the rest spaces. The cell, however, still thinks that they are actual characters so the cells always display the ellipsis, even when it is actually empty (only spaces). I have looked for a way to format it with the DefaultCellStyle. ...Show All

I would like to set the dataSource for the other comboBox based on the item selected in comboBox1.  when the datagrid is first loaded, it takes the details from DataBase.  When the cell is in Edit mode, ComboBox will appear, and uses can edit the data by selecting an item from the ComboBox (say, Product Type).  Then, based on the Product Type selected, other ComboBox in the DataGrid (cbxSize, cbxColor) are then binded to the range available for that selected Product.

• .NET Development Can't run web services locally.

  Hi, I can create a web service, post it to my host and then use it.  But I can't use a service on my local machine.  I'm running Windows 2000 Professional.  When I try it always says "can't create type classname".  I figure this is because the web service isn't running on IIS like in v1.1.  But I can't figure out how to make the web service run so that I can then run my web app locally and step through it.  Any ideas on how to do this   Thanks!  Ken. Hi, I found out that if I put the services in a different solution I can get that solution started with the web server th ...Show All

• SQL Server need help, How to change datatype in order to sort some extracted numbers from string

  Hello, I am trying to extract from some strings like the following strings the number and order them by that number: Box 1 Box 2 Box 3 Box 20 Box 21 ...(and so on) The problem I am having is that I already extracted the number using Substring([field],[starting position],[lenght]) but the output seems to be in a string format, so the order is not in an ascending order. Thanks for any suggestions. You need to cast the result as a number. It looks like your number is always an integer so the following should do it: (DT_I4)Substring([field],[starting position],[lenght]) -Jamie ...Show All

• Visual C# Nice Threads!

  I could really use some help here... I am using C# 2005 and have created a splash screen that runs on a seperate thread. I can invoke the splash screen in the Main() method, but then I can't get rid of it! I am attempting to put a line in the Form1_Load (or maybe Form1_Shown) that calls a static method in the splash screen to close that form. But, when I do so, it complains about an invalid cross-thread operation. How can I get this screen to close Here are the relevant parts to my splash screen: // Static Public Method to launch Splash Screen static public void ShowSplash() { if (ms_frmSplash != null) return; ms_Thread = new Thread ...Show All

• Visual Basic VB.net 2002 vs 2005 Express

  I switched to VB.Net quite a while ago now and still use the 2002 version. I tried the express version a while ago but was put off by the new click-once setup facility. Do any of the new Express versions have a Deployment add-on like the older versions where you can build a setup.exe to include a setup.msi, instead of the click-once version   The more inclusive versions such as Standard, Pro and Team Suit have more comprehensive deployment capabilities which I prefer to one click.
