I want to loop thru ever element of an array and if a condition is met modify that element. It seems For Each would be the elegant way but I can�t figure out how to put a value back in the array. Below is what I eventually used. It goes thru every element and if there�s a tab in the string it eliminates everything after the tab. Can I do the same with For Each?[code]...

I have a problem with form instantiation. This is what I want to achieve: I want to create forms with a toolstrip attached to them right from the moment these forms are instantiated. I have several ideas:
1. making custom Form Control
2. modifying the new method for forms
I'd like to focus on idea 2. I want to know if there's a way to alter the in-built New() method, so whenever the compiler instantiates a form, somehow when the constructor(New method) of each form is invoked, the compiler adds a toolstrip to the form.

I have an assignment I need to make and I have to make an app where the user can create a map/floorplan.So basically they open up the program go to create or edit and they should get a blank or already made floor plan.After that they should be able to add new icons/components to the floorplan or change them location wise on the floor plan.I have been searching into custom user controls and a few post I found on the internet about dynamically creating buttons.The dynamically creating buttons could do if the users can modify their locations and if it could save the whole form after being altered.However I want to be pointed in the right directions and know if any of these will work before I start doing more research and going more in depth.

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I'm using HTMLAgilityPack in a parser that I have up on a server, but I'm having issues with one of the websites that I'm parsing: Every day around 6am they tend to shut down their servers for maintenance, which throws off the Load() method for HTMLWeb, and makes my app crash. Do any of you guys have a more secure way of loading a website into HTMLAgilityPack, or maybe some way to do error checking in C# to prevent my app from crashing? (my c# is a little rusty). Here is my code right now:
HtmlWeb webGet = new HtmlWeb();
HtmlDocument document = webGet.Load(dealsiteLink); //The Load() method here stalls the program because it takes 1 or 2 minutes before it realizes the website is down

I have a rich text box that I want to show as un-editable and un-selectable text. If I set Read-Only to YES and Enabled to NO, then I get the desired effect...
...except disabling the control changes the background color to the washed out grey. I'd like to keep the background color white.

As I have been working on a project from a development book for self learning, I am having a problem with Dragging and dropping on my form. My form has labels that represent questions on one side and labels on the other side to be drag/dropped as the answers. I understand that under the element's properties there is Dragdrop and you can work with that, but how exactly do I actually make the element drag/drop? I want to be able to click and hold the element to drag drop, just as you would for reorganizing preferred settings or for my case of a drag/drop Q and A form.

I am trying to take a string that I have marked up through vb.net code and cross-check it with the text file it came from originally. This is for proofreading the html output.To do this, I need to parse an HTML snippet that does not come from a URL.The examples of HTMLAgilityPack I have seen get their input from a URL. Is there a way to parse a string of marked-up text that does not include a header or similar parts of a well-formed webpage?

I'm using the HTMLAgilityPack to parse HTML pages. However at some point I try to parse wrong data (in this specific case an image), which ofc fails for obvious reasons. Code:
How to check whether the content is 'parse-able' before trying to parse it to prevent the error? For now it is an image which makes an error popup however I think it might be just anything which isn't (x)html.
