Stupid Regex Issue Jamie Nordmeyer13-Nov-06 4:59 Jamie Nordmeyer 13-Nov-06 4:59  OK, this regular expression works great with the System.Text.RegularExpressions.Regex object: ^\d{3}(-?)\d{2}\1\d{4}$ but bombs out when used with Javascripts (IE7) RegExp object. I'm not using any options (multiline, ignoreCase, etc.). Has anybody heard of issues with the IE 7 Javascript engine having issues with back references, or any other weird regex stuff?

NEVER, EVER, forget that Javascript, like C/C++/C#, requires that \ be written as \\. :-> Kyosa Jamie Nordmeyer - Taekwondo Yi (2nd) Dan Portland, Oregon, USA Re: Stupid Regex Issue ednrgc13-Nov-06 5:20 ednrgc 13-Nov-06 5:20  have you used the @ setting for the string or quallified the slashes? Re: Stupid Regex Issue Jamie Nordmeyer13-Nov-06 5:29 Jamie Nordmeyer 13-Nov-06 5:29  The @ setting doesn't matter in my case, as the Regex string is being written to client script for use by the Javascript RegExp object. Thanks for the thought, though. No, that's always the first thing I check. This was just me being a bone head and forgetting to use \\ instead of \. D'Oh!!! Kyosa Jamie Nordmeyer - Taekwondo Yi (2nd) Dan Portland, Oregon, USA Re: Stupid Regex Issue ednrgc13-Nov-06 9:08 ednrgc 13-Nov-06 9:08  Forgive my ignorance, but if you're writing a script with C#, wouldn't the @ make it literal, thus be written as is? "^\d{3}(-?)\d{2}\1\d{4}$" <= wouldn't work. "^\\d{3}(-?)\\d{2}\\1\\d{4}$" <= would work @"^\d{3}(-?)\d{2}\1\d{4}$" <= result is same as above Re: Stupid Regex Issue Jamie Nordmeyer13-Nov-06 9:22 Jamie Nordmeyer 13-Nov-06 9:22  No, you're right. When I said that the @ symbol wasn't the issue, I meant that my C# code is fine; the regex pattern is ^\\d{3}(-?)\\d{2}\\1\\d{4}$. However, this is written to my javascript as ^\d{3}(-?)\d{2}\1\d{4}$, and thus the \ charector is stripped from the string by javascript BEFORE it is passed to the RegExp object. My code had to be modified to use ^\\\\d{3}(-?)\\\\d{2}\\\\1\\\\d{4}$ Kyosa Jamie Nordmeyer - Taekwondo Yi (2nd) Dan Portland, Oregon, USA Re: Stupid Regex Issue ednrgc13-Nov-06 9:25 ednrgc 13-Nov-06 9:25  I was hoping that was the problem. I was about to rumble through my c# books on regex thanks Re: Stupid Regex Issue Jamie Nordmeyer13-Nov-06 9:26 Jamie Nordmeyer 13-Nov-06 9:26  Just think if there were another layer, and you had to write ^\\\\\\\\d{3}(-?)\\\\\\\\d{2}\\\\\\\\1\\\\\\\\d{4}$ Kyosa Jamie Nordmeyer - Taekwondo Yi (2nd) Dan Portland, Oregon, USA Text editor in c# veluru krishna13-Nov-06 4:44 veluru krishna 13-Nov-06 4:44  can anyone tell me how to create text editor in c#.

Re: Text editor in c# ednrgc13-Nov-06 5:14 ednrgc 13-Nov-06 5:14  No Re: Text editor in c# Jamie Nordmeyer13-Nov-06 5:21 Jamie Nordmeyer 13-Nov-06 5:21  You can't expect anybody to do your homework for you, which it appears is what you want based on the rest of this thread. What you CAN do, is browse through CodeProject, and look for samples, of which there are plenty. If all you want is a basic text editor (no syntax coloring, etc.), you can do so with a multiline text box. Then, just add in menus to the main window, and a context menu to your text box, and you're set. If you're looking for an advanced editor, then you're going to need to use the Rich Text control (or roll your own, which is orders more difficult). Either way, you'll have to do the work yourself, and not expect someone else to do it for you. If someone else does it, you don't learn anything, and we end up with another programmer in the job pool who can't hack it in the work force.

Re: Text editor in c# aamironline13-Nov-06 6:06 aamironline 13-Nov-06 6:06  There are some open source text editors available. You can start by looking their code.

Making a control visible from Form.OnMouseEnter Jon Hulatt13-Nov-06 4:02 Jon Hulatt 13-Nov-06 4:02  Hi all, I want to make some controls on my form visible only when the mouse is over the form. To that end, i set Visible=true in the onmouseenter event of the form, and visible=false in the onmouseleave. However, when you move the mouse over the controls that are newly made visible, the onmouseleave event fires and the control is made invisible again. Then, since the control disappears, the onmouseenter event fires again, start a cycle of flickering. Can anyone think of a way round this? I can see no way of telling where the mouse went (ie, did it leave the bounds of the form? or did it enter a control on the form) and thus no way of properly implementing this feature. Any ideas? thanks jon using System.Beer; Re: Making a control visible from Form.OnMouseEnter ednrgc13-Nov-06 5:21 ednrgc 13-Nov-06 5:21  Have you tried placing the control on a div, and showing/hiding that? Re: Making a control visible from Form.OnMouseEnter Jon Hulatt13-Nov-06 6:26 Jon Hulatt 13-Nov-06 6:26  I'm sorry i wasn't explicit. This is a Windows Forms application, hence the title stating Form.OnMouseEnter. Thanks Jon using System.Beer;
