I have a situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:
sParams(0) = "All"
sParams(1) = "State"
sParams(2) = "Insurance"

I have had a look at 2010 to see if any options have been added to
System.StringSplitOptions
and we still have;
None
or
RemoveEmptyEntries

I thought about how the String.Split method works.
Often I have wanted to split a string on the characters that terminate a sentence such as a full stop >> . << ,
a question mark >> ? << or an exclamation mark >> ! << and still keep the string split characters.

lbltime.Text.Replace(lbltime.Text, lbltime.Text.Length - 2)That does nothing, no error but it doesnt remove the last 2 characters from the string.

It gets to the Remove but it just doesn't delete the characters from the string.
When I try to remove the last few characters of a string, I get an index out of range error. I am using the following to remove the characters from the end of the string:
objJSONStringBuilder.Remove(objJSONStringBuilder.Length - 1, 6)
The string has <hr /> at the end which I want to remove.
Removing the first 8 characters from a text string. How can I do it?
View 6 RepliesI need to parse an alphanumeric string leaving the characters "0-9", ".", "/" and space & remove everything else. I use "[^0-9./ ]" as my regex string and it works well. But now I have a couple other conditions that I dont know how to handle with my regex string. I actually only want to keep the "." character if it falls between two digit characters (ie. 3.5), otherwise remove it. And also I need to replace any "-" characters with a space if it falls between two digit characters (ie. 2-1), otherwise remove it.

I am trying to strip the first 75 characters from various strings (sentences / phrases) and it seems right but I need to ensure that the now words are truncated in the process. Meaning that if the 75 character is part of a word it needs to fall back to the beginning of the word or nearest space..
I thought of stripping the entire string into separate words and then counting the length of combining the words and stopping when I reach the target but what do I do in the case when it is not a valid sentence just a bunch of characters jammed together. I thought of using grammar parsing tool libraries and parsing into tokens etc but that seems to over complicated.
if text.length() > 75 then
ctext = text.remove(text.length, 75) & "..."
endif
I put elipses at the end but using the above I also get the error:
does anyone have any better suggestions.
I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

View 7 RepliesI am trying to split a string into array. I know about split, but it seems to need a separator of some type. Suppose I am going to be working with input like the following. 8561369 and I want to split each character of that string into an array. I tried something like this, but again Split seems to need a separator, I just keep getting the entire string in one entry of my array, not split. Dim values as String 'I am going to be populating this string variable via user input eventually, 'which is why I cannot just add spaces. values = "8561369"

I have a program that requires a string. The string is 20 characters long. The string also have to be split into 2 words the first word is 12 characters and the second is 8. If the strings is not 20 characters long I get an error. I wanted to know how can I get the program to start back over and let me enter another 2 more words if the string is not 20 characters long. At the moment after I get the string is not 20 characters long error it continues to read the rest of the program but I want it to stop after an error and let me start over from the beginning.

I need to separate each value and put it in an array. typically it would be done by ".split". however I need it to be split in this order: 0, 50, 100, 200, 400 etc.. In other words, I need it to read the rows left to right. I have no problem separating each number, I just need it to read it in the specified order. I've tried the regexp and I forgot to mention that after each line there is a line break. I am not sure if this would impact the regex, but in any case, after i do the regex, I get the following order: 0, 6.65, 84..??, 35.... etc
I am not getting the order I need as stated above
Expected results: 0, 50, 100, 100, 200, 400, 218, 9.8, ???, 6.65, 6.31 etc...
I am going to follow some of the suggestions below by splitting up the string into separate lines initially. this code almost does that:

I want to split a string with this array of char

dim palabras as String() = RichTextBox1.Text.ToString().Split(sepa)
I tried:

View 12 RepliesEssentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

I have a textbox which has about 120 lines of text but this can vary. I want to search for an array of words, like Boeing, Airbus, Saab etc there might be 3 options there might be 5 options in this array that i'm looking for. My question is how can I search the textbox and highlight all these words? Similar to (Control + F) in IE8. I've looked at InStr but am unsure if this is what I'm after as it does not seem to work for me.

Currently, my application will send the contents of a directory into a list box.
Dim folderDlg As New FolderBrowserDialog
folderDlg.ShowNewFolderButton = True
If (folderDlg.ShowDialog() = DialogResult.OK) Then
ListBox1.Text = folderDlg.SelectedPath
Dim di As New IO.DirectoryInfo(folderDlg.SelectedPath)
[Code] .....
For now, all that is inside the directory is a text file. I would like my program to read the contents of the text file and remove a set of common words, but I don't really know how to move forward here. Would it be best to create a class that holds a set of words that I would like to remove, then loop through the text file, remove any words that match those inside my class and then write what's left to a new .txt file?
How to correctly convert string containing upper ASCII characters to byte array besides looping through each character and filling the array using AscW(chr)?I know I can do something like:
Code:
Dim bSourceData As Byte() = System.Text.ASCIIEncoding.GetBytes(sourcedata)
But this only works for lower ascii characters (0-127).Instead of ASCIIEncoding I can specify encoding myself (System.Text.Encoding.Getencoding(encoding).GetBytes(sourcedata)). But I have to specify correct encoding in this case, otherwise most of special characters are converted to "?". What should I do if I don't know the encoding?
