ASCII Text Formatting - TextBox To File?
Oct 22, 2010
So I'm using a plain TextBox to display output from an ongoing background process. I've created a 'report string' that displays in my textbox like it has 3 columns; there's a VariableName, a VariableValue, and a VariableEffect (showing how applying that variable to the process affected it).In my textbox, any VariableValue entry that has 17 or greater characters gets 1 tabstop between Value and Effect; any entry 16 or less gets 2 tabstops, and any value 7 or less gets 3 tabstops which very neatly lines up the 3 columns.

what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

I've made a user control (http:url.....)I'm trying to format the text based on the data type e.g.:
Date
Numeric - 2 Decimals
Numeric - 0 Decimals
String
Now, I've added a property so that the user can decide at design time, what format he wants for the textbox. I've also made the options an enum. And then the coding in a sub. But not sure what I have to do with the sub.When I put it in the TextChanged event, then I get the weirdest behaviour from it.LIke when I typed in 1234 on Numeric0Decimals, after I typed 4, the cursor jumped to the first position of the textbox...On type Date, I just type in 2009/08 and then again it just jumps to the front and set the text to 01/08/2009 .So obviously can't place the sub in the textchanged event...
Private msTextConversion As TextConversionOptions
Enum TextConversionOptions
DateType[code]....
I'll obviously still change my sub to make sure that the text entered is numeric,or string, or valid date etc. Just didn't get around that part yet.

Simple question, what would be the optimum code in VB2010 to read in a text file and verify that:1) It is a text file, and2) There are no non-ASCII characters anywhereAnd conversely, we would want the code to provide a warning if the file is not a text file, or if the text file contains non-ASCII characters. [Note that LF, CR and EOF are expected to be in the text file, and should not be flagged as errors]

I would like to pass a whitespace character by using the System.Text.Encoding.ASCII.GetBytes(" "), and System.Text.Encoding.Unicode.GetBytes(" ") , where " " is the whitespace Character required. What do I need to type (" ") to get a whitespace character passed.?

I am using visual basic 2008 and trying to create an application to plot data from text files. I have several data files of various sizes. They have an unknown number of rows and either 2 or 4 columns.I need to put the data into 2 dimensional array, so value(,) becomes either value(lines,3) or value(lines,1) depending on the number of columns.My program needs to be able to count how many columns there are, and redim value(,) appropriately.I have written a piece of code to count the number of lines (rows) in the file using 'While not (EOF(1)) ....' but I'm stuck on how to count the number of columns.I could ask the user to indicate how many columns there are before the file is read, but I would prefer the program to detect the number automatically.

1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above).Include suitable headings. Note that you cannot assume that the file contains onlyresults for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
The output might look as follows:
Home Team Away Team Home Team Goals Away Team Goals

I just want everything to line up nicely. Would I need to make my own function to do this or is there a way with string.format or regex?

I have a VB Application that is loading an Array with Numbers from the Sequel Server that have numbers 315054 no cents and leaving the .00 off even numbers. I need to write out the number to a textfile that has 14 zero's to the left removing the decimal point from the number.
The Number should format and be written out like this:
00000031505400 in the text file.
My coding does this as long as the even number has a decimal point .00 but if the number comes in as 315054 into my array my coding gives an Argument error with the coding below.
SCreditTextBox1 = Microsoft.VisualBasic.Right("00000000000000" & Microsoft.VisualBasic.Left(_sData(Irow, 7), _sData(Irow, 7, ".") - 1) & _
Microsoft.VisualBasic.Right(_sData(Irow, 7), 2), 14)
Is there a way to check for no decimal point and then place the number with no .00 as 00000031505400?
The accounting people are entering the numbers into the server this way incorrectly. The .00 is suppose to be entered with it, but not all even numbers are entered this way without .00, just a few, but I need to check the number to see if there are decimals and without decimals do something. Could my coding be re-written to account for not having the .00 and to format the number correctly to avoid the argument error?
I need for any number to format with:
$3,000.00 would appear in server as 3000 or 3000.00 and should write out like this below: I need to check for decimals and without decimals and writeout the format like this below:
00000000300000.

I am writing a 2D array to a text file.Is it digital map data, so I write each row at a time, and the format is readable by my map application.I have pasted the code below. The array is called edgegridArray. Everything else is pretty obvious. I don't know if streamwriter is the best way to do things,
Dim swr As StreamWriter = New StreamWriter("D:edgeoutput.txt")
swr.WriteLine("ncols " & cols - 2)
swr.WriteLine("nrows " & rows - 1)

I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:
± 3
The TextFieldParser is returning
? 3
I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.

I'm working on decoding a NMEA sentence that is a compressed 8-bit string. I'm having a very hard time of wrapping my head around the bit manipulation needed to convert this string. If someone could get me started with this it would be great.
Here is the incomming string:

Years ago when coding with VB6 and earlier, I used a file open command to create, read, and write a file that made it easy to store useful information.I believe it was binary and you wrote/read the data to a specific line in the file. When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.

I have lines of text that contain "degree symbols" (ASCII(248)). I want to replace those symbols with an alphabet character (Z).I am changing the line of text into a charArray,iterating through one character at a time. How do I define the ASCII(248) in code to replace each occurence with a Z? Something like string.Replace(ASCII(248), "Z") would be nice, but that doesn't seem to work too well.

I want to format several textboxes so that they would accept a decimal number like 2356.90. Now, let me first describe to you how I designed the designers view.. or rather I am going to attach what I did.
Ok... first the textbox SUM OF THE BILLS i would want to display two decimal point places.. so that when a person clicks the click for sum button, it calculates the sum of the bills and places it in the textbox. I got this code so far...
Code:
Private Sub txtJanuaryBillsSum_TextChanged(sender As System.Object, e As System.EventArgs) Handles txtJanuaryBillsSum.TextChanged
txtJanuaryBillsSum.Text = Format(Convert.ToDouble(txtJanuaryBillsSum.Text), "####.##")
[Code]....
Everything was fine and it was running ok but when i added the code for the format of the textbox I suddenly got that error.

I'm having trouble getting a numeric format out of a textbox.I can do this in the textbox validating event, but I need commas to be entered into the textbox as the user actually types the data, not after they leave the textbox.. the reason is that they are typing really large numbers and can easily lose track of 0's or the total number if there are no comma seperators.I tried to do this through the keydown event in the textbox, but that doesnt work the comma gets inserted but the cursor goes into the begining of the string so anything new i type goes ahead of the old stuff.is there really no formatting on the properties level of a textbox??? how can there be no datamask?

I'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string?
For example. The txtboxCodeEntry looks like this:
If strVar="dummy" then 1 else 0 Endif
I would like it to "autoformat" to:
If strVar = "dummy" Then
1
Else
0
End If
The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE.

All - I have a form that has two databound textboxes on it. To keep it simple, they are: Quantity & Value For BOTH of these text boxes, the TEXTCHANGED action will multiply the two and present the result in a LABEL. This works 100%.

For BOTH of these text boxes, the TEXTCHANGED action will multiply the two and present the result in a LABEL.This works 100%.NOW - If I choose to add formatting to either of these text boxes, the calculation will not work. As one might guess, QUANTIY is formatted as NUMBERIC with zero decimal places and VALUE is formatted as CURRENCY with 2 decimal places.
