Re: Randomize and Unique Numbers NickiG5-Jul-06 2:23 NickiG 5-Jul-06 2:23  Hi Tristan, Thanks, I don't suppose you can give me a clue with where to start with the coding (yes I am completing new at this) This is a sample of the coding I have to gentrate the numbers and the Randomize: Private Sub btnGenerate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerate.Click lblLottoBall1.Text = CStr(Int(Rnd() * 49)) + 1 lblLottoBall2.Text = CStr(Int(Rnd() * 49)) + 1 lblLottoBall3.Text = CStr(Int(Rnd() * 49)) + 1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Randomize Re: Randomize and Unique Numbers TristanJ28-Jul-06 4:31 TristanJ 28-Jul-06 4:31  Private Sub btnGenerate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerate.Click lblLottoBall1.Text = CStr(Int(Rnd() * 49)) + 1 Do Until (lblLottoBall2.Text <> lblLottoBall1.Text) lblLottoBall2.Text = CStr(Int(Rnd() * 49)) + 1 Loop Do Until (lblLottoBall3.Text <> lblLottoBall1.Text And lblLottoBall3.Text <> lblLottoBall2.Text) lblLottoBall3.Text = CStr(Int(Rnd() * 49)) + 1 Loop End Sub Like i said this is a bit inefficient, but on the other hand it looks like you're writing a windows app so timing shouldn't be a huge issue. Plus most of the time it won't have to regenerate a number anyway (only one time in 25 i think?) so you're gonna have very little overhead anyway, mainly just from the comparisons. Regards, Tristan Jones Re: Randomize and Unique Numbers Guffa4-Jul-06 11:24 Guffa 4-Jul-06 11:24  Here is a neat way of doing it: www.guffa.com : Random without duplicates[^] The code is in VBScript, but you should easily be able to convert it. The code itself is not complicated, actually it's surprisingly simple. It's the theory behind the algorithm that is clever. --- b { font-weight: normal; } Add Scrollbar Control to my form Wael Hawari4-Jul-06 5:10 Wael Hawari 4-Jul-06 5:10  hi everybody, plz if any one could help me in this pb i need to add a scrollbar to my form & i want to activate them, i mean that i want when i press on the horizontal scrollbar, my form start to move. can anyone help me plz on this i be very thankfull. waelhawari Re: Add Scrollbar Control to my form Dave Kreskowiak5-Jul-06 5:44 Dave Kreskowiak 5-Jul-06 5:44  Well, it's possible, but a bit of a pain to handle, depending on what you're doing with them. If all you're doing is putting a bunch of controls on the form and trying to move them around because the form is too small to show them, you're really wasting your time. All you need to do is drop a Panel control on the form, dock it so it takes up the entire surface of the form, set its AutoScroll property to True, then put all your controls on the panel. It takes care of moving everything around for you!

Yikes... The only other usable container control, IIRC, is the PictureBox. There is no Panel control like there is in .NET. If you have that many controls on the form, you REALLY need to rethink your UI. Break down what each part of this form does into smaller parts and dedicate them to their own forms. I direct you to the Official Guidelines for User Interface Developers and Designers[^]. This describes the concepts behind a good user experience.

I'm trying to display a user drawn menu, the same way I already did so many times in standard Windows application, by using the DrawMenu & MeasureItem couple (and of course the UserDraw property set to True); but I'm getting no output, just a blank line, even the text ("View logs", for instance) disappear, though if I click on the item I get the expected behaviour (the log window appears). By the way, another difference with the standard Windows app, is that I'm defining the menu items in the sub Main (since I have no form) Can someone please help me. Thanks in advance Marco Turrini Get thumbnail for files other than images JohnWillemse3-Jul-06 22:24 JohnWillemse 3-Jul-06 22:24  Hi, I'm trying to locate sample code or a free library to extract thumbnails for Office documents, in particular Excel and Word.
