I've come across a character in one of my data feeds, which I have never encountered before
The images above are the data feed in Notepad++ and Notepad view. As you can see it appears as 'BEL' in Notepad++ and a sort of 'bullet point' in Notepad.
How would I go about replacing this character in vb.NET?
I've tried a simple replace in a SSIS Script Task by copying and pasting the character into the replace function, e.g.
text = text.Replace("copy and pasted character", "")
and this gives this error
All help is extremely appreciated,
Thanks
I’ve got no idea what SSIS is but since you wanted to know a solution in VB.NET, the code you’ve tried will work here. That is:
text = text.Replace("copy and pasted character", "")
will work just fine in VB. Alternatively, you can use the following:
text = text.Replace(Chr(7).ToString(), "")
Find out what the Ascii value of the character is and then use the Chr function to eliminate it
i.e.
text = text.Replace(Chr(n), "")
[Bell] is probably character 7

I want to split an XML Code after an command i.e. ....<car>BMW3</car>
There is a lot of stuff in front of this command so I would like to use the Splitfunction with "<car>" as delimiter.
Is there a way to make this possible or is there another function or VBA code to make this happen?
Thanx in advance :)
That should do it : Replace String with your whole text, and WordDeliminter with your delimiter.
SPLIT(SUBSTITUTE(String,WordDeliminter,";"),";")
I am working on a macro that needs to be able to check and make sure that a character on a certain line is what it should be before it finishes the form.
Where or how do i find the information to do this?
I have tried using the command "Left(#of line ,1)" and am not getting it to return anything at this point.
I Assume that you have this text in a string. Comment to my answer if wrong.
You can use a Regex to compare to string with your character like so :
If Regex.IsMatch(MyString, *.{X}Y) Then
'You have to manually replace X for the number of characters before the character you scan for
'You have to manually replace Y for the-said character it is supposed to be
Look at http://www.codeproject.com/Articles/9099/The-Minute-Regex-Tutorial for more info on Regex.
If you want to only take one line in your string :
TheLine = split(MyString,Environnement.Newline)([Line Number])
I have a text file which contains about 60 lines. I would like to parse out all the text from that file and display in a window. The text file contains words that are separated by an underscore. I would like to use regular expression to solve this problem.
Update:
This is my code as of now. I am trying to read "filename" in my code.
Dim filename = "D:\databases.txt"
Dim regexpression As String = "/^[^_]*_([^_]*)\w/"
I know I don't have much done here anyway but I am trying to learn VB on my own and have gotten stuck here.
Please feel free to suggest what I should be doing instead.
Something like this:
TextBox1.Lines = IO.File.ReadAllLines("fileName")
To remove underscores:
TextBox1.Lines = IO.File.ReadAllLines("fileName").Replace("_", String.Empty)
If you also need other special characters removed, you can use Regex.Replace:
Remove special characters from a string
Also on MSDN:
How to: Strip Invalid Characters from a String
Or the old school way - loop through all characters, and filter only those you need:

I tried looking around for this particular problem, but couldn't find it.
I am trying to replace an assortment of characters in a string.
I tried looping through the characters using their character codes, but my code will ?randomly? delete the entire string instead of just the special characters. (basically I just want the letters and numbers from the string) EG. ABC-3.3%H14T-6 I would just want ABC33H14T6
What is strange about this (to me) is that my code will delete the string on a random character, it's not always chr(41) or whatever, it changes each time I run the code.. is it maybe a formatting issue?
For Char = 33 To 47
Sheets("Sheet1").Cells(FRow, 44).Replace What:=Chr(Char), Replacement:="", LookAt:=xlPart
Next Char
I would give you the bulk of my code, but it is work-sensitive.
Any advice would be appreciated!
Thanks guys.
I'm dumb Chr(42) = *
which would replace everything. durr
Hey, I'm trying to figure out how to display the ▼ character properly in a .NET winform application.
I am creating a custom control, and for the button, I want this character to appear. I am able to set the text to this character, but it appears as a blank square.
Any ideas on what I need to do to make this character appear properly on my forms?
I am using Arial font, which is compatible with this symbol.
EDIT: It is currently being set as follows:
btnCalendarToggle.Text = "▼" 'Yes, it appears exactly like this in my code
More information on the character can be found here:
http://www.fileformat.info/info/unicode/char/25bc/index.htm
EDIT2: I tried adding some other Unicode characters, and got the following message:
"Some Unicode Characters in this file
cannot be saved in the current
codepage. Do you want to resave this
file as Unicode in order to Maintain
your data?"
After clicking YES on this message, it still didn't work. It appears that the encoding method may be wrong for the file... I don't know what to set it to. Has anyone else tried to display this character in a winform before?
There can often be issues (both with source control systes and diff tools) if you embed more complex unicode characters in source files.
It is often better to do it via an explicit escape sequence and keep the source file in a simpler encoding.
btnCalendarToggle.Text = "\u25BC";
If this works it is likely that the problem is instead the encoding settings for the source file.
Are you certain however that the font in question is Arial (try debugging and checking) since regardless of the above mentioned issues so long as the encoding is set to a legitimate Unicode one (and Visual Studio will convert the file for you if you embed such a character in it) this should have worked.
Can you post the code you are currently using ?
You can print out characters using the chr(int) function if you know the character code.
Dim i As Integer
For i = 0 To 255
txtTest.Text = txtTest.Text & Chr(i) & " -- " & i.ToString() & Environment.NewLine
Next i
Try that and see if your character prints out.
