Custom Datagridview cell mp9920053-Jan-08 0:43 mp992005 3-Jan-08 0:43  Hi all, I need a datagridview cell of containing multiple datagridview cell.If it is possible then pls tell the way of code. Re: Custom Datagridview cell LongRange.Shooter1-Feb-08 9:57 LongRange.Shooter 1-Feb-08 9:57  If I understand your question correctly, you want what is known as heirarchical data grids. In maybe version 1.0 this was supported. But in the 2.0 framework on it does not. The only way to get that working is to either a) write your own heirarchical datagridview or b) buy one. Any way to get all TreeNodes in a TreeView have the '+' symbol? jeffb422-Jan-08 10:20 jeffb42 2-Jan-08 10:20  I'm dynamically populating a tree as the user selects nodes. Prior to clicking on a node, parent nodes actually have no children and after click, they get populated. This results in expandable nodes not having the "plus" sign next to it until after you click on it. Anyone got any ideas on smart ways to make every node have a plus sign, whether it has a child or not?

When a node is expanded, you check the children of the node for the "dummy" child node. If it's there, remove it and populate the children as you see fit.

OnStart is used to start a seperate thread where your service does all it's work. OnStart is expected to start this processing thread and return control back to the Service Control Manager inside of 30 seconds. Your code does all of it's processing, and I'm suspecting does a Thread.Sleep in there somewhere, in the OnStart method, never returning control back to the Service Control Manager.

Re: how to find out number of instantiations of a form Luc Pattyn7-Jan-08 9:12 Luc Pattyn 7-Jan-08 9:12  Hi, if you want to know how many instances of a specific class exist, you should add some code to that class, including: a static int counter, a property to get its value, and one or two events to increment and decrement the counter. For form visibility, the event would be Form.VisibleChanged Luc Pattyn [Forum Guidelines] [My Articles] Happy 2008!

This provides an easy to use way of packaging your app with MSDE. http://www.microsoft.com/downloads/details.aspx?FamilyID=6e9a7403-c4ba-4d98-bb0b-2c9d6414071f&DisplayLang=en[^] I hope this helps.

I filled it like this : lbox.DataSource = 'some datatable'; lbox.DisplayMember = "Col1"; lbox.ValueMember = "Col2"; The SelectionMode chose is : MultiSimple I need something like this foreach (item in the selected items) { Display its value.. etc } Thank you. Re: Browsing a ListBox Luc Pattyn28-Dec-07 6:14 Luc Pattyn 28-Dec-07 6:14  a ListBox has a lot of useful properties, some related to the current selection; I would not be surprised if the documentation would show some with names starting with Selected. Would you care to read up on them? Luc Pattyn [Forum Guidelines] [My Articles] Happy Holidays!

But If i change it..it doesn't get serialized to InitializeComponent() so at runtime it still has the default value I created a UIEditor for this property and a BrushConverter : TypeConverter to let the design-time know how to convert from a InstanceDescriptor to a Brush. Why doesn't this work? I debugged the design-time and when I change the property..the breakpoint in the method ConvertTo from the type converter doesn't hit Thank you in advance.
