VS 2010 : Removing Characters From A String?

Nov 22, 2011

I 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 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:

Regex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?

Dec 21, 2011

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.

VS 2010 Removing Line From Either String Or Textbox

Aug 3, 2011

I have strMyString that contains about 5000 lines of data. There are some lines of data that need removing if they contain a certain string, such as "http", "www.", ".com", "cat", "fish", etc. The whole line needs removing. Each line is separated by a vbNewLine or similar.

How can I do that? Does it need pasting into a rich textbox first before processing?

VS 2010 Special Characters In String Text?

Apr 14, 2011

I'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...

When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?

Catching And Removing Escape Characters In A Serial Comm Port Program?

May 18, 2010

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.

VS 2010 : Fill A "gap" After Removing A KVP In A Sequential String Key Based Dictionary?

Jan 2, 2012

I need to remove an instance in a class for which I also created a dictionary with a string key type. Like this...:

vb
'Declare dictionary
Public PersonsList As New Dictionary(Of String, Person)
'At the bottom of frmMain.vb

[code]....

As you see, I end having 120 instances of the class Person, each assigned with a string key consisting in "student1" to "student120".

At other parts of the program I repeatedly refer to PersonsList("student" & n) to set values at those class entries, mainly with a For n ... Next block.

Now... I need a routine to remove one of those instances for good, including its entry at the dictionary, so my first bet is this...:

vb
Public Sub ExpellStudent(ByVal student_index As Integer)
PersonsList.Remove("student" & selected_student_index)
students_count -= 1
End Sub

I assume this is good enough to remove the KVP at the dictionary AND the class instance proper... right?Well, even if that is ok, I foresee one problem... Let's say I removed "student46". Next time I run a For n = 1 to students_count I would bet that I'll receive an exception due to having a gap at "student46" KVP... and that without saying that students_count will be 119, so it will never reach "student120".In short, I need a way to reassign the KVP of the now 119 Person entries, so they're consecutive again (I don't care about them changing their string key values), so I still could use my For n = 1 to students_count ... Next blocks without problems... but I cannot figure out how.

Error When Getting A Substring Of X Characters Out Of A Parent String Of Less Than X Characters?

Feb 23, 2011

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!
