Also, i combined your code and SBerthold code so the user cannot paste data either from keyboard either with righ click on it. I wanted to disable right click so the user couldn't cut-copy-paste whatever from one textbox to another and that's because as i mentioned before, i have a kind of validation in several text boxes and i wanted anyway to prevent this, because if with i copy or cut paste data to from one to another textboxes it would be a problem for exampble if a textbox accepts only numbers for some calculations. Hypetia the what i wanted to do firstly, was what exactly you have done in thread222-588883: Right click in a textbox: Right click in a textbox RE: Disable right click popupmenu of textboxes SBerthold (Programmer) 20 Jun 07 05:38 Unfortunately, I cannot find a reliable way of modifying the default menu of a textbox and disabling/removing the Paste menu item from it. This leaves more work to do on your part. Similarly, if the user chooses the Undo command then you have to send WM_UNDO message to undo the last change.

Also, you have to prepare your menu before displaying it and process all commands which user will choose from your menu by sending appropriate messages to the textbox in question.įor example, you have to send EM_CANUNDO message to determine the enable/disable state of Undo command before displaying the menu. You should combine the above two techniques (disabling paste function and showing a customized context menu). This popup menu will mimic the standard text box context menu, having Paste function disabled or missing altogether. Instead of completely disabling the context menu, you can display a customized context menu of your own when WM_CONTEXTMENU messasge is sent. Similar to the code for disabling paste function, I posted code in thread222-588883: Right click in a textbox for disabling the context menu. Clipboard is a shared system resource and clearing it just to solve the purpose is not a decent idea in my opinion. If TypeOf node_here.Tag Is FactoryData ThenĬtxFactory.Show(trvOrg, New Point(e.X, e.Y))ĮlseIf TypeOf node_here.Tag Is GroupData ThenĬtxGroup.Show(trvOrg, New Point(e.X, e.Y))ĮlseIf TypeOf node_here.Tag Is PersonData ThenĬtxPerson.Show(trvOrg, New Point(e.X, e.I would never clear the clipboard.

' See what kind of object this is and ' display the appropriate popup menu. Private Sub trvOrg_MouseDown(ByVal sender As Object, ByVal _Į As ) Handles _ĭim node_here As TreeNode = trvOrg.GetNodeAt(e.X, _ The routine then checks the type of the node's Tag object and displays the appropriate popup menu. The trvOrg_MouseDown event handler uses the TreeView control's GetNodeAt method to see which node is under the mouse. These objects don't do much in this example but you can give them whatever data you want. It makes a FactoryData object for a factory node, a GroupData object for a group node, and a PersonData object for a person node.

It sets each makes an associated object for each node and assigns it to the node's Tag property.
