Replace ONLY If Text Matches Item?
Oct 24, 2009
i have a listbox w/items. that when running code, the rtb, if it contains a listbox item, it replaces it.. no problem there..the problem i'm facing is that if i have the word "To" in the listbox, by using .contains, when running text in rtb, if i have "DeskTop" as a word in rtb, it ends up replacing the "To" in "DeskTop"..
i have tried the intellisense menu to the limit on finding something other than .contains to use in order to only replace if it matches exactly the item in the listbox. no luck. ;o/

I've been working on this RegEx for the past day or so and I think I have it worked out so that it returns the data I want. First a little background.I have a content editor that users will be able to edit web pages. They can format text, add links, etc.. standard content editor stuff. When they click save, the editor provides the ability to get the content (editor.Content) and put it into a string. What I want to do is get any links (<a> tags) and find out if they are internal or external links and if they are PDF files.
Here is the Expression I've come up with:
<a[^<>]*hrefs*=s*[""'](?<domain>https?://[^/s'""]*)*/?(?<path>/?[^s""]+?)?[[>""']
With this, I am able to separate the domain (if it has one) and the path out. Then, I loop through the matches...
dim matchColl as MatchCollection = Regex.Matches(editorContent, regExString)
For Each m as Match in matchColl
If m.Groups("domain").value <> myInternalDomain and m.Groups("domain").value <> "" then
'this is an external domain... do some stuff
[code]....
My question is this... the parts where I 'do some stuff' to the values, what would be the best way to get that back into my 'editorContent' string? I could probably put the editorContent into a StringBuilder and do a whole bunch of replaces on it, but is that very efficient?So, for example, with the PDF, I want to specify that it open in a new window (target="_blank") and for the external URL, add some javascript code into the onclick attribute.

I'm trying to find a good way to parse through text and only get certain matches, like say someone puts the text "My name is Bob" in a textbox, then it puts the text "<Tag>My name is Bob</Tag>" in another textbox, and my problem is, if that person were to put..."My name is </Tag> Bob" in the textbox, when the RegEx match is found, you would only get "My name is" as a match. So how can I make sure that the text input no matter what it is will not interfere with the <Tag></Tag> when using the RegEx:
(?<=(<Tag>).+?(?=(</Tag>))

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I'm trying to integrate a parental controls feature on my webbrowser. Now, the user creates a text file containing a list of the words they don't want their child searching. Here's an example of what would happen. The list looks like this (I wont use vulgar words):
dog
cat
baby
fish
tree
and the kid tries going to "treeandbabynectar.com". I want a messagebox to come up saying "Site blocked". I want it to be able to detect the tree and baby in treeandbabynectar and realize the text file contains the word tree and baby and block the site. Is this possible? How would I do this?

I have a textbox which has a numeric value that changes - would it be possible to check if that value matches two numeric values in a text file? and if the value matches then to display some text in a label? The textfile only has fields displayed like so
Horizontal 55
Vertical 16
So I would only need to check if the numeric field in textbox matches the two numbers in the second column. In the past I have use System.IO.File to create/delete/append to files but I havent come across anything like contains.

I have a database with a table that is a child to many other tables. I am using this child table as a datasource for a datagridview. I am using comboboxes to display specific fields in any parent tables, instead of the user seeing the foreign key. Everything is fine. However, I would like to filter the BindingSource based on text matches between any of the fields in the child table and the corresponding fields of the parent tables.

I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

Document.Content.Find.Execute("Subject/ Title:", , , , , , , , , "Subject/ Title: Insert Subject here")
I found the code above that is extremely useful for my project. It replaces the first string with the second. But now I need to bring my code one step further. I would like the text from after the colon to be underlined. I tried using a range but it didn't work. Secondly, that only works if there's text to look for in the first place! I would like to put text in an empty cell. How do I locate the cell programmatically? It's the second table in the document's second row.
