I've got a bunch of web page content in my database with links like this:
<a href="/11ecfdc5-d28d-4121-b1c9-1f898ac0b72e">Link</a>
That Guid unique identifier is the ID of another page in the same database.
I'd like to crawl those pages and check for broken links.
To do that I need a function that can return a list of all the Guids on a page:
Function FindGuids(ByVal Text As String) As Collections.Generic.List(Of Guid)
I've run across some VB.NET code that explicitly creates three GUID constants and uses them in a class's ComClass attribute. I've written COM-aware classes in the past just by checking the "Make COM-Visible" and "Register for COM interop" options in the project options. Is this explicit code simply unnecessary, or is it doing something above-and-beyond what those two options do? Here's a snippet:
<ComClass(MenuHandler.ClassId, MenuHandler.InterfaceId, MenuHandler.EventsId)> _
Public Class MenuHandler
Public Const ClassId As String = "A2204623-A902-44d4-B524-FDFFCD176E53"
[Code].....
Paste the below into a C# Project and all is fine:
public class Test
{
public delegate void RandomEventHandler<T>(T newValue);
[code]......

View 2 Replieswhat is the code for finding the shortest,average and longest sentence form the text box
View 4 RepliesI have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
I'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...

I have a little question about txt-files...This is the case: I am going to make a small software for editing particular parts in text files, so you don't have to do it by hand. In this program, i need to find several words in a text file and retrieve the text or number that is after the the "="-sign, and then replace that info. Then, I want to use the information it retrieves to add some text in the end of the file.
P.S. There are 36 differet words to search for, and some of them will occur in several places, so i want the data from those words that occur several times in an array. And the data i want to retrieve is AFTER the searchword and a "=", so i dont want the searchword or the equals-sign included. Can someone explain to me how to do this?

View 5 RepliesI would like to find text in a richtextbox. I know the code to find a string, but.My find button is in a context menu.I thought it would be a good idea (which usually turns out not to be so good to have a text box in the sub-menu. So, the person would click on "find" and the side menu would open (with the text box), one would then type the search string into the textbox and hit <return>, upon which time the search would be executed.I'm not sure how to implement it. I'm starting to think there might be several issues since the menu system opens the textbox automatically etc. How will I get the string since the textbox won't be "called" by the find button.Can anyone give me some help as to how to procede with this method, or if this method seems daft, then perhaps point me to an alternate or 'standar' approach for this?

I am trying to find all text from a slightly older application. The thing is, the old scripit from windows NT finds the text I need no problem, but I cant seem to get it myself.
I find the main window, and cycle through its children, but must be looking at something wrong. I am missing 2 things: The title of the app has the name, and then some status information, the status information does not show up on the window title info. The text in the application itself does not reveal itself to me either
Here is a code snippet of how I try to get the info out:

So say that I want to find the word "Hello, world!" on a webpage. It has the ID "Text". Using a WebBrowser named WebBrowser1, is there a way return true if that text exists on a webpage, or if it doesn't exist, it will return false? The URL would be EXACTLY the same either way.
Edit: The HTML path to get to it is very long, so I'd need to find the text on the page.

View 1 RepliesI am making a program for work, i have it partly coded, unfortunately i don't have a wifi connection for my laptop right now which makes it hard to add my code here. What i am trying to do is have the user pull in a text file from anywhere on the computer using a open file box that pops up, i got that part, to make sure that is working i have a textbox that reads the data of that text file, it gets pulled in fine using a stream reader. Now what i need to do is search the text file for certain values, and depending on the selected item in the listbox which is on another form, change that value in the text file, im guessing i will need to use a stream writer, and ive seen examples used based on the file location(C:....) but in my case im not sure how to do it.
