• Visual Basic class library

Personally for any one who is serious about programming, it is just one more re ...Show All

• Visual Studio 2008 (Pre-release) Wish: Get WebService reference to generate ObservableCollection<T>

  Sorry if this isn't pure WPF. Flame me if you wish. Since WPF extensively uses things like ObservableCollection<T> and the related INotify... interfaces, I would like it if there was a nice way to have my web service reference do things like this when calls return an array: Give me a checkbox to have my class generated with INotifyPropertyChanged (xsd.exe /edb option). Instead of putting the collection in a standard array (MyItem[]), let me choose to have it wrapped in a generic collection, such as ObservableCollection<MyItem>. Just in case I don't want to use ObservableCollection, let me choose a different collection ...Show All

• Windows Forms How to detemine in which grid of TableLayoutPanel a mouse click occurred.

  In the mouse click event handler for a TableLayoutPanel I need to know in which row / column the click occurred. How would I do this Thanks. Normally a TableLayoutPanel has a control in each cell. Those child controls would handle the mouse click event. Otherwise, you'll have to iterate the rows and columns of the TableLayoutPanel during the TableLayoutPanel's Click event and calculate the cell that was clicked based upon the RowStyles and ColumnStyles properties of TableLayoutPanel. ...Show All

• Visual C# ?porting to VC++?

  I have heard about ppl doing it but how can it be done, im guess porting vc++ to C# would be a nice trick to know how to do. can someone explain or point me into a direction of where I can read about it. thanks Basically you need to know both languages, as each has facilities that the other does not.  So, it depends on the application how easy it is to port, and I doubt it would ever be a completely trivial task.  I find it easier to expose C++ code via C++/CLI to be called by C#, I've done that with some of my old C++ image processing code a few times, and also to access C++ SDKs from C#. ...Show All

• Smart Device Development infrared!

  Hi. I want to be able to send data (hex codes or whatever) using the infrared ports. I have imported the System.Net.Irda reference and able to access the IR classes. However, I do not wish to connect to a device but rather send data. The device I am sending data to will be a dumb device really, just as a "reciever"... this can be a remote control recieving box or a TV IR reciever for example. IS it possible to do this how I cannot seem to find a way in the .NET classes as it seems you have to connect to the destination then write data to the stream. Thanks!
