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.
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.
View 8 RepliesRemoving 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.

A usual input would be

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"

Essentially 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.

Currently I have a class that checks for apostrophes and doubles them up like this
Shared Function CheckForBadCharacters(ByVal MyString As String)
Dim finalstring As String = MyString
finalstring = Replace(finalstring, "'", "''")
Return finalstring
End Function
Works fine, of course i need to reverse this when retrieving - however is there a better way ?

I have recently developed a serial port communication program to access my hardware firewall and its connected to the device via a converter usb to rs232head plugged to a rs232 to an ethernet cable. this ethernet cable then plugs into the device console port.
my program functions similar to that of TeraTerm. an opensource hyperterminal program written in C++ but i decided to do one for vb.net
Alright to cut the story short, i have successfully coded out the program to accept incomming data from the device but however, i'm also receiving ansi escape sequence along with it and i have no idea how i could implement codes to remove these. i have spend 3 weeks trying to look for vt100 emulation codes written in vb.net but i found none so far. most are written in c++. here's an image to illustrate the problem which im facing.
The image below is a screenshot taken when the i ran both the programs together. The bottom is tera term 3.1 and the top is my vb project which i made using msdn's example and improved on the codes. basically tera term was able to interpret those escape sequence and display accordingly to that of the vt100 terminal display. I have spent time reading on regular expressions using the inbuilt function regex in visual basic and tried parsing some strings but its not working. i guess its far more complex than i thought.
im working on a small application that lets you input a phone number with "-" hyphens, and then copy that number to a label control minus the hyphens. So for instance 111-234-567 would become 111234567, i have accomplished this using the string.
replace command, however i was wandering if it would be possible to iterate through the string with a for next loop looking for the hyphens and then removing them with the string.
remove command, ive spent nearly 5 hrs trying to get the code to work, but to no avail, no errors are being thrown up, but the hyphens still display along with the number, i am currently teaching myself, and its a sloooooooow process. here is my unsucessful code

This is probably quite a simple question, but I can't remember how to do it off hand.I have an e-mail address of "foo@bar.com".I want to grab the @ and everything after it and then I'll be adding a prefix to the front of the address as I go.
I'm just wonderng how I get hold of the @bar.com from the string?
I know I should know how to do this as this is a really simple operation.
My.Settings.regLibCardNo = "10-0000"
I want it to increment
CODE:
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I'm suppose to end up with a label box with my name spelled out in it using string manipulation. This is suppose to happen using the concatenated string to output the name into the label box. I don't have any error codes but I also don't have my name in the label either. [code] "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. [code]
View 2 RepliesSo I have a string "New". What is the simplest way to convert that string to "New". Basically right now I'm doing this:
Case "NEW"
makes = connector.GetMakesByYear(_AuthorizationKey, "NewCar", CDate(Now), Year)
Case "USED"
makes = connector.GetMakesByYear(_AuthorizationKey, "UsedCar", CDate(Now), Year)
And I would prefer not to use a case statement because it's only one parameter that needs to change, and both are appended with "Car".
The idea is simple, if I have a string value "ABCD" then with a ButtonClick event it should randomly reveal a char while others are hidden. i.e, "B*" another click would "AB**" and so on. So far, my I have been stuck in a for loop.

So I'm working on a software in VB.Net where I need to scrape information and process it according to rules. For example, simple string replace rules like making "Det" into "Detached" for a specific field, or a split/join rule, basic string operations. All my scraping rules are RegEx and I store them in a database in rows of rule sets for different situations.What is the best way behind creating/storing rules to manipulate text? I do not want to hardcode the rules into the software, but rather be able to add more as there will be a need for them. I want to store them in a database, but then how do I interpret them?
