I have a richtextbox in a form that opens a text file line by line.
Each line contains texts that is to be imported elsewhere and is delimited by commas.
The first two fields are dates and are fine. The remaining fields are all text and need quotations inserting.
For each line of the richtextbox is count the commas as it works through the string. For the first two nothing needs to happen. for the third comma a quotation mark is needed to the left (",); for count of commas 4 to 7 a mark is needed either side[code]...

I have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.
View 5 RepliesI would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.

My original example could be solved using other methods. This example is more representative of the actual problem:

View 5 RepliesI have a long string of HTML code that contains several quotes around objects in the string. I have a Regex.Replace() function to change the "img src" tag, due to the way its stored in a database.
Here is my string: <p><strong><u><font color="#cc0099">RICH TEXT BOLD UNDERLINE. PICTURE TO APPEAR BELOW</font></u></strong></p><p><strong><u><font color="#cc0099"/></u></strong></p><p><img src="/inlineimages/WorkOrder/6/1245981403232.jpg"/> </p><p /><p>W00T!</p>

Notice how the "<font color=" has single quotes around its value, and "<img src=" has single quotes, with a double quote jammed in between?
Also, is there an automated way to go from my initial string, to the "Dim input As String" I created? I had to manually type that out, editing the quotes just to try and make it work.
I am looking for a way to replace keywords within a html string with a variable. At the moment i am using the following example.
returnString = Replace(message, "[CustomerName]", customerName, CompareMethod.Text)
The above will work fine if the html block is spread fully across the keyword.eg.
<b>[CustomerName]</b>
However if the formatting of the keyword is split throughout the word, the string is not found and thus not replaced.e.g.
<b>[Customer</b>Name]
The formatting of the string is out of my control and isn't foolproof. With this in mind what is the best approach to find a keyword within a html string?

How can I replace character/word in text (loaded to richboxtext) but only for those which are not on the "block" list ?
Dim str As String = RichTextBox2.Text
RichTextBox3.Text = str.Replace("1"c, "A"c)
But I want add list of words which should be excluded. I thought that I can do something like :
Dim str As String = RichTextBox2.Text
If Regex.IsMatch(RichTextBox2.Text, "shows") Then
Else
RichTextBox3.Text = str.Replace("%"c, " "c)
End If
RichTextBox3.Text = str.Replace("1"c, "A"c)
Dim str2 As String = RichTextBox3.Text
RichTextBox3.Text = str2.Replace("2"c, "B"c)
But it's not working as it will just skip replace of % for whole text and I want just just exclude particular word from list from being replaced...

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.
