I am interested in learning to write programs in C#, and am hoping to pick up as many things as i can through the questions i ask on this forums. Even if they are stupid. I have my program working thanks to the help on this forum, So again, i appreciate all the help And i apologise for any future stupid/ignorant questions. Re: CheckBox initial value Luc Pattyn28-Aug-09 4:24 Luc Pattyn 28-Aug-09 4:24  No need to apologize, everyone is new to something at some point. However, rather than spending 100+ hours at asking 100+ questions and reading and testing all the answers, good and bad ones, you'd better take this advice[^]. And then ask more intelligent questions when they arise. Which we will be glad to answer.

Beginner questions are allowed, but real basic stuff should be known before being let loose with Visual Studio (or one of the Express Editions) and an internet forum IMO. Don't be afraid to ask. A good book, and working through (and understanding) some online tutorials is a must though. We will happily help whilst you learn, but not hold your hand if you understand what I mean.

Henry Minute Do not read medical books! You could die of a misprint. - Mark Twain Girl: (staring) "Why do you need an icy cucumber?" “I want to report a fraud. The government is lying to us all.” Does exist this user control. Fired.Fish.Gmail28-Aug-09 2:40 Fired.Fish.Gmail 28-Aug-09 2:40  To support such function: Can draw three column a, b, c with the images. User can use the scroll bar to control the column a,B Column a and b are opposite. Column c is static. User can draw 10 rows of column a,b to the column c. then the program can draw the lines from the row of colun A to the row of column B. Does anyonthe know the user control can do this? If I design this user control? how to achieve it? thks Re: Does exist this user control. Henry Minute28-Aug-09 8:26 Henry Minute 28-Aug-09 8:26  What? Henry Minute Do not read medical books!

Fired.Fish.Gmail28-Aug-09 16:10 Fired.Fish.Gmail 28-Aug-09 16:10  I need one user control that can support user draw. Column A Column B A1 B1 A2 B2 A3 B3 A4 B4 A5 B5 A6 A7 A8 A9 A10 1.When user can select 3 rows of Column A and draw to row B2 of column B, three line will be created from a1 -> b2, a2 -> b3, a3 -> b4. 2.There are 200 rows in Column A, A1 -> A200. User can uses scroll bar to control which rows of column a to show. Re: Does exist this user control. Henry Minute29-Aug-09 3:11 Henry Minute 29-Aug-09 3:11  AFAIK there is no control that does this, or at least I could not find one. What you are describing sounds rather like a graphical database designer or query designer works. If you google for c# database designer or c# diagram designer, you might well find something that you can get useful code from, or at least ideas. It seems to me that you will need to build your own control, and if so I would suggest that you use ListBoxes for ColumnA and ColumnB. You will need to research Drag and Drop, and for drawing the links I would suggest that you create a class that contains the starting listbox, the item (A1, A2 etc.) from that box and the same for the ending listbox. Then when a link is needed create a new instance of the class and add it to a list. when your control needs to paint itself, you just iterate over the list drawing a line from the start listbox to the end listbox.

Calla28-Aug-09 2:53 Calla 28-Aug-09 2:53  I've been doing a lot of service installations from a WinForm, and I prefer to use the methods in advapi32.dll via p/Invoke.

Is it possible to lit the num, caps and scroll lock light on a regular keyboard with a C# program? Re: Lit the Num, Caps and Scroll lock light? Keith Barrow28-Aug-09 2:14 Keith Barrow 28-Aug-09 2:14  It's not easy, you have to Interop with windows. See this codeproject article: Read and Update CAPS or NUM lock status from your application[^] Re: Lit the Num, Caps and Scroll lock light? Mc_Topaz28-Aug-09 4:37 Mc_Topaz 28-Aug-09 4:37  Thanks! Re: Lit the Num, Caps and Scroll lock light? DaveyM6928-Aug-09 2:18 DaveyM69 28-Aug-09 2:18  You can read the state easily, but to set/toggle it requires some PInvoke I believe. There's a MS article here[^] with code in VB as an example. Dave BTW, in software, hope and pray is not a viable strategy.

Tried to understand your solution, but it's maybe to advance for me, not much code-comments either. But your solution proves that it's possible to do lit the keyboard lights with a C# program. Now I know it's possible Re: Lit the Num, Caps and Scroll lock light? DaveyM6931-Aug-09 8:53 DaveyM69 31-Aug-09 8:53  If you either copy the files in the Keyboard project into your own, or add a reference to the Keyboard.dll file to your solution, you don't need to worry about how I've implemented it - you can just use the properties, events and method(s) of the ToggleKeyController class as I have done in the demo (if you look at the code in FormMain.cs).
