Manipulate A String To Byte Swipe?

May 27, 2011

I am trying to write a code that will byte swipe data in a string.

The conversion should take a 16 characters string, and swipe the first to characters with the last two, then characters three and four with character thirteen and fourteen and so on, in this format if the input string is

A1B2C3D4E5F6G7H8 then the converted sting will be H8G7F6E5D4C3B2A1.

I run into problem using: left(mystring 2) and right(mystring -2) because the string to manipulate is an input of a textbox so I fail when I try to use cross data with a StringHandling class, and how to incorporate StringHandling into my form class and without it when I try something like

Dim byte1 As String = Left(MyString, 14)I get an

error saying - Public ReadOnly Property Left As Integer has no parameters and its return type cannot be indexed.

VS 2010 Manipulate ObjReader As A String?

How do you manipulate a text file once you have opened it with Streamreader? I can get the streamreader to open the file and display it in a text/listbox but i cant do things like split and join to it.... It has no effect on the text file when viewed.

This is how i am setting up my string array:

Dim fileName As String = "C: est.txt"
Dim objReader As New System.IO.StreamReader(fileName)

how do I manipulate objReader as a string?

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!

Question Reading Raw Text As String To Manipulate

Feb 29, 2012

I am not sure if this makes sense or not, but I need to process raw text (without any encoding?) that I retrieved from a file recovery application "PhotoRec".With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.[code]I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "current byte". So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

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.
