  is there a way to allow only ' a-z A-Z 0-9 ][{}()-* ' characters to be typed into a normal textBox the MaskedTextBox wont work in the way that i want it too. Im using VC++ 2005 thanks Hmm.

• -D- C# drag and drop between forms

  I've been trying to figure out how to drag and drop between two forms (i.e applications in C#). I created two forms. One form with a treeview and the other form with a textbox. What I wanted to eventually accomplish was to be able to drag the node name from an item on the treeview (form 1) to the textbox (form2) Therefore, I created the first form with a treeview, a few nodes and the itemdrag event. I created the second form with the dragdrop event and dragenter event and the textbox to capture the node that was dragged over. private void textBox1_DragDrop( object sender, DragEventArgs e) { if (e.Data.GetDataPresent( typeof ( TreeNode ))) { ...e.Data.GetData( typeof ( TreeNode )); } } Is there ...Show All

• Ido Ran Updating a databinding

  Hello. I have a ComboBox binding a DataTable, when i changes the values in the DataTable ... i don't see the changes in the ComboBox.
