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!

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.

Replacing Characters In Textbox (including Special Characters)

Aug 5, 2011

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.

If I enter a quote " in textbox1, it has to be replaced with " in textbox2.

I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "

Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

Shape Of Really Large Characters Such As Numbers And Alphabetic Characters

May 9, 2011

With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.

1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?

2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?

VB Mixing Characters When Change Position Of Two Characters In Word

I'm making an application that will change position of two characters in Word.

Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.

Asp.net - Character Support - Translate Higher ASCII Characters To Lower ASCII Characters?

Aug 7, 2009

So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.

The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?

Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?

Adding Characters To A String

Apr 2, 2010

I have a string value (which is a hex value) that is displayed as so...F8 30 00 3D FC 13 F8 30 00 01 31 73 34 FE 34 DE F8 30 00 3D FC 13 F8 30 00 01 31 73 34 FE 34 DE F8 30 00 3D FC 13 F8 30 00 01 31 73 34 FE 34 DEThis continues on in this exact pattern. What I am trying to do is to get a " " inserted after the first 24 characters, and then after the next 24, delete a character and place an Enter or Return value. Then I would like another " " after the next 24, and then after 24 more, delete a character and place an Enter or Return value so on until the end of the string. The format would then look like this.[code]I know this is probably done with some type of array and loop, but I'm not even sure where to get started.

Asp.net - Fix Special Characters In String?

Aug 3, 2010

I've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„¢ or â€" etc"

When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.Here's how I build the text file (where feedStr is a StringBuilder)

objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()

Get Number Of Characters In A String?

Jan 30, 2010

I have a query to solve for which I have coded. But my code produces output only for those hardcoded values found in the text file. I have a text file which is given as the input to my code. The text file contains lines with "_DIA" , "_DIA_some number" etc. In this case I need to remove few letters from that field.

Eg: 1)if the name field contains 1234567_DIA_2.PRT, I need to remove "_DIA_2" from the name field and concatenate the .PRT with the number. 2)if the name field contains 1234567_DIA1.PRT, then remove "_DIA1" and concatenate. I need to store the number of characters removed and add so many number of blank spaces with the name field after the concatenation.

for the 1) case I need to concatenate and add 6 spaces with the name field. for the 2) case I need to concatenate and add 5 spaces with the name field.

I'm not sure how to find the number of characters from "_" to ".", underscore need to be considered in the counting and the dot(.) should not be taken into account.

How To Get X Number Of Characters From A String

Mar 14, 2010

I'm attempting to modify some random password generator code, and wanted to do something a little different. I would like to list all uppercase, lowercase, numeric and special characters next to a text box. In the four text boxes, you would select how many characters from each set you would like in your password. For example 4 uppercase, 2 lowercase, 3 numbers and 2 special characters. That would generate a random password 11 characters long. I can generate random passwords now, and have included a text box which allows the length of the password to be specified, but i would like the granularity of selecting from each set.[code]
