Joshua Quick14-Dec-05 7:03 Joshua Quick 14-Dec-05 7:03  You need to create an ImageList object. Add images to this and then pass its reference to your ListView. You can create a large (typically 32x32) and small (typically 16x16) ImageLists and assign them both if you want. It'll use the large ImageList for the Icon view and the small one for the Details/Report view. You can also just use one ImageList for both large and small if you want, and the images won't change size in the list. lstDSNode_Fill.LargeImageList = myLargeImageList<br /> lstDSNode_Fill.SmallImageList = mySmallImageList You can then assign an image to your ListViewItem by giving it an image index. mItem.ImageIndex = 0 'Assigned 1st image in list. One more thing. The following bit of code that you had is inefficient. There is no point in calling AddRange() if you're always only going to add 1 item. Plus you're allocating an array here every time. .Items.AddRange(New ListViewItem() {mItem}) I suggest that you change it to the following. .Items.Add(mItem) Grid Points in static variables within private subs lysis_lysis13-Dec-05 23:19 lysis_lysis 13-Dec-05 23:19  Hi from Sydney Anyone know if you can declare a "local static variables" value to a Public variable and preserve the Public variables contents after exiting the private sub? I hope this sounds right? Thanks... Lysis Database Connection AminMaredia13-Dec-05 21:37 AminMaredia 13-Dec-05 21:37  Hi, I have access database on Windows Server 2003.

Execute EXE file from VB macro Analog1913-Dec-05 21:28 Analog19 13-Dec-05 21:28  Hi I need to execute an EXE file from VB MACRO defined in outlook. Need some example code and guidence for the same. Regards Anandan Re: Execute EXE file from VB macro Dave Kreskowiak14-Dec-05 16:24 Dave Kreskowiak 14-Dec-05 16:24  I'm assuming by "VB MACRO" you mean VBScript. In that case, click[^].

But please clarify me onething. Is the code which we write in outlook macros (Microsoft office outlook objects-ThisOutlookSession) is VB Script ? Regards Anniyan Re: Execute EXE file from VB macro Dave Kreskowiak15-Dec-05 5:11 Dave Kreskowiak 15-Dec-05 5:11  Inside Outlook (not Outlook Express!), and all the Office applications for that matter, the language is Visual Basic for Applications (VBA), not VBScript. The two languages are closely related, but there are differences between them. If you wanted to run an external application, you'd have to have the Windows Scripting Host do it for you. In your VBA Code Editor, go to Tools, the References (I think!), and set a reference to "Windows Script Host Object Model". The you can write code like this to get an external app to run: Dim ws As New WshShell ws.Run("notepad", 7, True) RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome Hello from South Africa!

Re: password keeper..... Dave Kreskowiak15-Dec-05 4:55 Dave Kreskowiak 15-Dec-05 4:55  There a couple of problems with this. First, what's stopping someone from just "Ending" your app when it starts? Nothing... Second, there is no increase in security that your app could possibly offer on PPC. So what's the point?
