• Visual Basic Context Menu Item Click, using my own code

  Ok, I'm trying to use code to create and use a menu strip. I can get the menu to open, but I'm having trouble handling the "onClick" event.

• Visual C++ Excessive rebuilds

  I have quite a bit of base code (a bunch of header files) that I reuse for many of my programs; I store them in a folder /Common Code/, and it has always worked fine. Just yesterday, without (knowingly) doing anything wrong, any program that I have that includes these header files forces a rebuild of all source files whenever I try to run or compile it, even when I haven't changed any code. I'm guessing that I accidentally toggled some command in the Visual Studio environment, but I've searched around the menus for a while and couldn't find anything. Does anyone know of any possible reason Thanks, Jesse Beder ...Show All

• Windows Forms TreeView duplicating nodes in Internet Explorer

  I'm having some serious problems with the TreeView control. I've got a control that inherits TreeView and has some methods that firstly create a TreeNode then does some recursive procedure to add all the children from a database of a sort. Then once this is complete I clear the nodes, then add the TreeNode so it should be the only root node. The only problem is that for some very VERY strange reason there are two root nodes, with duplicate child nodes. This is very bizare as this.Nodes.Count returns 1 and base.Nodes.Count also returns 1, so there SHOULD be 1 root node but there are two. Also, I created another TreeView inherited ...Show All

• Windows Forms How do I filter a BindingSource using the Child token?

  I have to DataTables with a parent-child relation set between them. The BindingSource object is bound to the Parent table. Is there a way of applying the filter with search/filter criteria specified for the child DataTable I've tried: ParentBindingSource.Filter = "child(RelationName).aChildCol='strToFilterOn'" but I get an error "Cannot interpret token 'child' at position 1." Any ideas on how this can be done After some research I've seen comments stating that Child can only be used with aggregate functions.
