VS 2005 Extra Newline Chars On File Append?
Dec 3, 2009
I am writing a program that will read and write to a file using the My.Computer.Filesystem namespace, and when I append my data file with the code shown below under SaveFile subroutine, it sometimes places extra ControlChars.Newline at the end of the appended text. Sometimes it places one extra newline, and sometimes it adds 3-6 newlines. I have tried everything I can think of to make it add just one newline at the end of each append, as I will be using the newline char to flag each entry on retrieval. I am working out some algorithms in this project to use in a project that will keep track of data in a file using csv format(just practicing saving/retrieving data from a file). The extra newline characters that are added will become a problem when I start to sort the data to display. my xSaveButton click event:
Private Sub xSaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xSaveButton.Click
Dim boolAppendData As Boolean
If My.Computer.FileSystem.FileExists("myData.dat") = True Then

I am using a masked text box to format phone numbers. However, I do not want the extra formatting that gets insterted from the masked text box: (800)-555-1212
All I want is: 8005551212
But I still want the user to type it in like this (to make it easier for user):
(800)-555-1212
I am thinking I can run a replace function on it, but I am not sure what event to use. I found a number of tutorials, but not that useful for what I am doing. [URL]

I have a class that's getting an XML document from a URL. I've verified that the XML from the URL has an newline at the end. For some reason, though, this newline is stripped off before being fed back to the user, which is causing an mal-formed XML error when the users feed this XML file into other programs.
Dim reader As XmlTextReader = Nothing
Dim filename As String = _partID & "_" & _majorRev & "_PreCheck.xml"
Dim localFile As String = fileDialog.FileName
Dim URLString As String = _env.HTTPInfo("stwebservices").UriBase & "PreCheckXMLReport.aspx?partId=" & _partID & "&rev=" & _majorRev
reader = New XmlTextReader(URLString)

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

I'm trying to use something simple this:
Dim Names() As String = {"Bob", "Bill", "Jim"}
Dim AllNames As String
For Each Name As String In Names
AllNames &= Names & " "
Next
Operator '&' is not defined for types '1-dimensional array of String' and 'String'
I guess I'm not trying to store each item in the string array correctly. How would I do this?

I have worked out all the other bugs in my Staffing app. A while back .paul helped me with exporting my data to excel. So what I need to do now is this:
Schedule AM RN's and export to excel DONE
Schedule PM RN's and export to excel appending to existing worksheet
Schedule AM NT's and export to excel appending to existing worksheet
Schedule PM NT's and export to excel appending to existing worksheet
Schedule AM WC's and export to excel appending to existing worksheet
Schedule PM WC's and export to excel appending to existing worksheet
I only need 1 workbook, and each new full schedule will be a new worksheet with the beginning date/ending date as the worksheet name.

i know i have to use a loop to get each line of the textbox onto a newline of a textfile but i dont know how to figure out how many lines of text the user has entered into a textbox. I tryed using a try statment to loop until it errors, it seems to work sometimes but other times it only takes half of the textbox and adds it to the textfile. And if atmaweapon reads this, i tryed to make better names for variables. Here is my code,
Code:
Path = ("Meals" & ComboBox1.SelectedItem & "" & TextBox1.Text & ".txt")
File = New System.IO.StreamWriter(Path)
If ComboBox2.SelectedItem = "1" Then
[Code]....
how many line of text there are... im not so shure how good it is to run a loop tell it errors for a textfile, but its the only way i could think of.

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 two RichTextBoxes, each of which can have any sort of formatting. I need to be able to take the rich text from box 2, complete with formatting, and add it to the end of box 1, preserving the formatting of both box 1 and the appended rich text.
I've not managed to find anything usefull on this anywhere apart from hints pointing to manually re-building the RTF codes for the result (but no actual VB / C# / C code to perform this or similar).

I am using a Microsoft Chart control (system.windows.forms.datavisualization.charting.chart) in a Windows forms application, vb.net 2008. I use folder paths for the x values in a pie chart. Chart control converts a name like c:ewfolder into c:[newline]ewfolder. I tried adding a slash, making it c:\newfolder, but this only changes it to c:[newline]ewfolder. Is there a workaround for this behavior?
some code:
Chart1.Titles.Clear() : Chart1.Titles.Add("Largest Folders in " & txPath.Text)
Chart1.Series(0).ChartType = DataVisualization.Charting.SeriesChartType.Pie
Chart1.Series(0)("PieLabelStyle") = "Inside"
Chart1.Series(0).YValueType = DataVisualization.Charting.ChartValueType.Double
Chart1.Series(0).XValueType = DataVisualization.Charting.ChartValueType.String

what im trying to do and what i have done so far is probably a little backwards not sure sure how to id it any other way.when the user generates an error because a particular file doenst exist ive got my dialoge box to generate an .txt file for each file it errors on, so that the administrator can check and update missing files as an when - shouldnt be many files missing in the first place, should just be new product ranges or item just launched.what im stuck on is:
1. is there a better way
2. how do i open a .txt file and add the extra lines to it, so i re use the file but keeping the previous data.

I have an array called lines() which is basically an array indicating which lines to read from a file. for example lines(1) = 0 means 'read the first line from the file', lines(2) = 4 means 'read the 5th line from the file' (counting from 0 not 1) The program first reads the file (which has a lot of random lines) so it can identify which lines match my criteria. The way I store the line positions is this:
For i = 0 to noOfLines -1 'total num of lines in file
If count = match Then 'this is my match criteria
lines(x) = i 'store the line in the array

I have been having problems with creating a download list of files for a downloader and was getting unexplained "File Does Not Exist" returns. My .avi files were returning found but but .exe and .txt files were getting the not exists.
I have now found by pulling in the whole directory and examining the file contents that my .exe files are showing ".exe.exe". My .txt files are showing ".txt.rtf". Wow, browsing the file directory in Server 2008 only shows a single extension. I don't see an option to display the extension as a column, just the "type". My directory looks like this:
Name Type
File1.exe Application
File2.txt Rich Text Document
File3.avi AVI File
I had renamed some of these files, maybe I just cannot rename files. I will try using originals ans see if I am ok. Maybe I need to rename the offending files without the displayed extensions. Is this just something weird with the server browser?

I've been asked to re-write an application that was written sometime ago by another programmer. This application reads data from a database table, massages it, and then writes out the results to a text file that is later shipped off to another company. When I run my new application, it generates a file that, according to the byte count, is twice the size of the file output from the old application. However, to look at the two files with note-pad they look identical. I found that by using 'Ultra-edit' that the new records have a low-value byte hex '00' between each real character.
