• Windows Forms Is it Possible ObjectDataSource and datagridview

  I have an objectdatasource bound to a datagridview in a Windows forms app. The datasource object has a boolean field. I can load and display the data ok. If there are 20 are so rows and the AddRow row (*) is not visible  everything is ok. However if the addrow row comes into view or the mouse hovers over the boolean field then I get the error in the DataError event:  "System.FormatException: Formatted value of the cell has a wrong type".  I tried setting the CellStyle Null Value to false and 0. I tried setting the true and false values. I tried putting default values into the ObjectDataSource's constructor. I can't se ...Show All

• Visual Studio 2008 (Pre-release) Move Event for a FrameworkElement?

  I'm trying to detetct a change in the position (ie Canvas.Left Canvas.Top)  property of a few FW elements. UpdateLayout is usually tripped (not always) and the sender is null in the UpdateLayout event.   Is there any other way Thanks Ron If you are binding in code, then as suggested on the other reply you should bind to the object directly.  binding.Source= fromObject; if you wish to use ElementName for an object you are creating in code, you have to first register the name with the corresponding namescope before the ElementName gets registered and will be found by the binding.

• Visual Studio Express Editions Is the Conservation Of a Computer System’s Resources a Virtue or An Evil?

  Hi There..... Is Minimal use of a Computer System’s Main and Auxiliary Memory a Virtue or an Evil Thanks You should tax the system's resources as little as you reasonably can. There's no need to write ridiculously complex code in order to minimise your app's footprint, but the fewer resources your app uses the more responsive a system will generally be overall, which makes for a better user experience. ...Show All

• Windows Forms How to have multiple panels?

  I'd like to implement a multi panel interface into my Windows Application. What I mean by muilti panel is where when a menu item is selected the appropriate panel shows in the the body of the form.

Basically, you will want to create a user control for each of the view that you would like. Specify the docking/anchoring on the widgets. O ...Show All

• Visual Studio MSBuild equivalent of Nant Solution task ...

  With Nant I can do the following: <solution configuration="debug" outputdir="${build.dir}">    <projects>        <includesList name="${Includes.List.Name}" />    </projects> </solution> Where includes.list.name is a text file list of .csproj files in my application.

• SQL Server Finding a tutorial for the complete beginner.

  Is there a tutorial or documentations for the "complete beginner" similar to the one made for VB.net express but for SQL Express I went over the Visual Web Developer Express tutorial but its only mention about sql was using the 'sqlcmd' command line tool with a copy and paste. What I'm looking for is actual docs on creating, editing, updating tables, records, etc. A GUI is what I'm really looking for; I tried using SQL Express Manager but it has no docs. Any help in the right direction is appreciated. Usually the SQL Server Books Online (BOL) offer first hand information and should really become your compagnion when dealing with SQL Ser ...Show All

• .NET Development .NET 2.0 Remoting TCP channel, is it bi-directional?

  douglasp (or anyone for that matter!), please could you answer if the TCP channel in .NET 2.0 has been updated to support bi-directional communications by default We have an application that is using a custom channel supporting bi-directional TCP and SSPI. However, the improvements in .NET 2.0 (native support of SSPI based security and the new IPC channel in .NET 2.0) are not easy to ignore given we could benefit from the use of the standard channels. Trouble is, we make use of the bi-directional channel to allow communications through network devices such as NAT routers, firewalls, etc. easier and losing this advantage would be s ...Show All

• Visual Basic Getting primary key of record just INSERTed

  Hi. What is the best way of inserting a row of data to an SQL Server database and getting the primary key (identity) of the record you just inserted - preferably in as few statements as possible I've not managed to find any examples of this on MSDN.
