Help with API Calls please.........I am at wits end :(

Raistlin Majer #1 / 3	Help with API Calls please.........I am at wits end :( Hi, my name is Kumaran I need to use 2 API calls in my VB App. 1) To get the NT logon name. I am using a SQL Server Database and this would expedite a lot if I could get the NT Logon Name. 2) I am using a Treeview Control, I have used popup menus on right clicks on certain nodes and items, the problem I have is that the Right Mouse Click does not shift the Focus Rectangle or change the SelectedItem as the Left Mouse Button does, meaning I have to LEft-Click first then Right-CLick. Please help me with this one. I am assuming it is an API call, I might be wrong though Thanking you \| \__/

josep.. #2 / 3	Help with API Calls please.........I am at wits end :( There are a couple of things that you can do here without API's. Since you HAVE the x and y coordinates of the click as I assume you are capturing all this in the mouse down event, you can manually set the SelectedItem property Set Treeview1.SelectedItem = Treeview1.HitTest(x,y) If you want the highlight there as well. Set Treeview1.DropHighlight = Treeview1.SelectedItem I had to add a LOT of code to this object to 'firm it up' Also you may get error 91 problems when youe code trys to reference the Selected Node and no node is selected. I write code that simply selects the root node in this case. Let me know how you make out Quote: >Hi, my name is Kumaran >I need to use 2 API calls in my VB App. >1) To get the NT logon name.

Please help me with this one. > I am assuming it is an API call, I might be wrong > though I assume you want the right mouse click to act like a left mouse click as far as selecting an item goes. In VB 3/WIn 3.1 I had a similar job to do except that I was using a listbox and not a Treeview control. I found that I could call GetCursorPos and convert to the proper coordinate system and that would tell me where the mouse had clicked on my form. Then I found that in a standard VB listbox each item is the same height as the TextHeight method for the appropriate font. Based on that it wasn't hard to calculate an offset from the top edge of the listbox and then add listbox.TopIndex to find which item had been clicked on. The most tedious part was converting between coordinate systems. Some functions return values in pixels relative to the upper left corner of the desktop, some return twips relative to the upper left corner of the form and you have to figure out of the width of the form's frame is included in that number, etc. Good luck Phil Save the Earth -- shoot yourself.
