Dial Up deanoA5-Aug-03 14:44 deanoA 5-Aug-03 14:44  Hi! How do you detect the duration of the dial-up connection? Please help me! And one more question, is it possible to use C# to transfer files programmatically? "To teach is to learn twice" How to do partial Regex matching? Alvaro Mendez5-Aug-03 12:04 Alvaro Mendez 5-Aug-03 12:04  I'm trying to use the Regex class to evaluate data entered by the user. However, since I'm doing the evaluation as the user types, I'd like the match to be successful even if all the data has not been entered yet. For example, if I have: Regex re = Regex("abcd"); And the user enters: ab I want re.IsMatch("ab") to be successful. Yes I know it's not a true match, but it's only because there's insufficient data. Is there an easy way to know this? Thanks in advance! Alvaro If you want to get to the top, prepare to kiss a lot of bottom. -- despair.com Re: How to do partial Regex matching? Arun Bhalla5-Aug-03 13:38 Arun Bhalla 5-Aug-03 13:38  Hmm. One way would be to use a pattern like: Regex("a(b(c(d)?)?)?)"); Not too elegant, but it would work. Re: How to do partial Regex matching? Julian Bucknall [MSFT]5-Aug-03 14:42 Julian Bucknall [MSFT] 5-Aug-03 14:42  Alvaro Any answer would of necessity be a specific workaround for a specific regex string. There is no way to generalize it, I'm afraid (apart from writing your own regex engine that allowed for partial matching).

Set the currentcell doesnt work in form load Ista5-Aug-03 9:50 Ista 5-Aug-03 9:50  I have this code to a DataGrid dgDataGrid1.CurrentCell = new DataGridCell(0,0); but it says I cant use it yet but if I move it to formLoad it will. And it is in formLoad event! what gives? nick I'm not an expert yet, but I play one at work. Yeah and here too. Re: Set the currentcell doesnt work in form load Marc Clifton5-Aug-03 14:13 Marc Clifton 5-Aug-03 14:13  This is just a wag, but maybe dgDataGrid1 hasn't been instantiated yet. Put a breakpoint on where you assign CurrentCell and another breakpoint on where dgDataGrid1 is constructed, and see which happens first. Hope that helps.

If your DataGrid is already populated, set the CurrentCell to a reference of a cell that actually exists - your code sets it to a reference of a new cell. If your DataGrid is not already populated, you may have to define columns/rows before being able to set a cell. Re: Set the currentcell doesnt work in form load Ista6-Aug-03 4:25 Ista 6-Aug-03 4:25  FormLoad() { dgDataGrid1.DataSource = myList; dgDataGrid1.CreateTableDefition(); // creates my table styles and applies them .. the current cell code ... } thats what it looks like. its instantiated, a data source has been set and a table style is created then a call to current cell go figure I'm not an expert yet, but I play one at work.

Is there an attribute to set to have it behave this way?

Re: Containter like controls Alex Korchemniy5-Aug-03 13:48 Alex Korchemniy 5-Aug-03 13:48  Well Duh! I have a custom control here and I need to do the same thing with it without deriving from Panel Re: Containter like controls Marc Clifton5-Aug-03 14:22 Marc Clifton 5-Aug-03 14:22  AK wrote: I have a custom control here and I need to do the same thing with it without deriving from Panel So, what features of Panel are you talking about? A panel is basically just a container for another collection of controls. But that's a property of Control, not Panel. It provides grouping for radio buttons. But that should be easy enough to implement yourself. Similarly with Panel's enable/disable feature--disable the panel and it's child controls are disabled. The only other thing about panels is the AutoScroll capability, which again may or may not be necessary but is fairly easy to recreate. And why not derive from Panel? If that doesn't work, then you can derive from Control but contain a panel, and pass through whatever functions you want to the Panel object and provide your own drawing. Maybe my article will help too: http://www.codeproject.com/cs/miscctrl/csoutlookbar.asp[^] Good luck!

What I was looking for is an attribute, or something simple to tell the VS.net designer to allow me to add child controls to my custom control. I don't need scrolling or anything extra. Just a way of treating my control as a control container. Thanks for your help. Re: Containter like controls Furty5-Aug-03 14:19 Furty 5-Aug-03 14:19  By the sounds of it, what you need to do is create a designer class for your control. Control designers are a complex subject, so I'd suggest looking up the MSDN doco, or look at some CP articles such as Jerry McGuire's designer for the Magic docking library for some insight. What is the @ for? Alvaro Mendez5-Aug-03 8:45 Alvaro Mendez 5-Aug-03 8:45  This should be simple to answer, but MSDN comes up blank. I've noticed some C# code with an @ in front of string literals: MyNameIs(@"Alvaro"); What is it for? Thanks in advance, Alvaro If you want to get to the top, prepare to kiss a lot of bottom. -- despair.com Re: What is the @ for? mikemilano5-Aug-03 8:48 mikemilano 5-Aug-03 8:48  the @ supresses escaped characters... for example: a windows path of C:\Program Files\ would normally have to be defined like this: string path = "C:\\Program Files\\"; because back slash is a character which must be escaped. if you use @, then it ignores special characters: string path= @"C:\Program Files\"; hope this helps. Re: What is the @ for? Eric Gunnerson (msft)5-Aug-03 9:06 Eric Gunnerson (msft) 5-Aug-03 9:06  It also lets you write multi-line string constants. The feature name is "verbatim string".

When another window is moved in front of the control and screws it up, it doesn't repaint. Do I need to set any style for the control to make sure it repaints when needed. Re: Control painting J. Dunlap5-Aug-03 8:42 J. Dunlap 5-Aug-03 8:42  You are repainting in the OnPaint method, right? There's no such thing as AutoRedraw in C# unless you make there be one.

Thanks for the help. All i did was set up wndproc and on WM_PAINT tell the control to paint Re: Control painting Arun Bhalla5-Aug-03 10:15 Arun Bhalla 5-Aug-03 10:15  Is that a better solution than invalidating that portion of the parent control (and the parent's child controls) in that region?

Well, overriding the WinProc allows you to catch specific messages, allowing you to customize the way the application works, in this case, when repainting is done. -Nick Parker Re: Control painting Csharp™6-Aug-03 0:23 Csharp™ 6-Aug-03 0:23  i posted a reply and it dissappeared anyway , invalidating a control should do the job, eg: button1.Invalidate();
