I am writing a little utility to generate some SQL files. I have a file which is generated from a string array of 400+ elements. It stops writing (without throwing an error) at arround 1000 characters or 380 lines. I am clearly missing something here. Question is what? I've tried (the remed lines of) flush but that seems to have no effect.[[code]...

I'm not sure what to call this so my search results weren't very helpful. I am writing an XML document that has computer paths and special chars such as '&'. XML does not like them, so I need to find a way to convert them.

I am coming across a lot of odd and annoying problems in this program and have almost had enough lol.
I cannot figure this one out for the life of me. I have used streamwriter a hell of alot of times and never once experienced this. But basically I have a string array and I need to write the entire array to a text file with a new line for each array item. So I have gone ahead and done this:
[Code]...
However the outcome is the text file only contains 1 line and that line is the last item in the array yet I know the array has got at least 50 items in it.
I have a problem when writing some text to txt files.Here is my My.Computer.FileSystem.WriteAllText("test.txt", tekst, False)where tekst is a string variable.
When opened in some HEX editor, test.txt begins with 3 unwanted characters - ASCII values: EF BB BF. Notepad isn't showing them.
I am writing each line to a text file:
Dim objWriter As New System.IO.StreamWriter(filename)
For Each x In tofile
objWriter.WriteLine(x)
Next
objWriter.Close()
Which works perfectly the only problem is is that when its finished it writes a blank line on the end of the text file which I don't want.
I have an issue with StreamWriter class. Basically, in an application running as a web service, I need to write info into a log file. When I send 2 web service calls simultaneously, the entries created in the log file are not correctly written. For example,
in call #1, ID 1 - xyz is to be written to the log file. In call #2, ID 2 - abc is to be written. When I viewed the log, it shows ID 1 - xyz & ID 1- abc. Looks like there's some memory data being shared and mixed together, even though it's totally 2 separate web service calls. From my understanding, each call (i.e. each will be process under a different application instance) should have its own set of memory allocation for data processing... If I am to make this application as a Console Application, it looks like everything is processed correctly.
I'm getting a problem when writing text files using StreamWriter. The files read fine and they write fine if I'm not overwriting an existing file. They also write ok as long as I'm not writing over a file that only has one digit at the end of the name. For some reason when there are 2 digits at the end it crashes when I'm trying to save over an already existing text file. Here's my code.
StringForTextFile = "C:" & Folder4PS & "" & IDCodewDashOrN & "Series" & Series & "ScreenNumber" & ScreenNumber & ".txt"
LblTesting.Visible = True ' Testing
LblTesting.Text = "StringForTextFile = " & StringForTextFile
[code]....
above but 've tried all the different Encoding possibilites. Unicode, UTF32, UTF8, UTF7 as well as without those parameters listed where the close parentheses is right after StringForTextFile. I get the same result. If I'm writing a new text file that doesn't exist, then no problem or if I'm writing over an existing text file but it has 0 to 9 at the end then I'm ok but if I'm writing over an existing file and there is 10 or above(haven't tried triple digits or all values) then my application crashes. You see the test label in the code above because I was looking at exactly what file it was trying to overwrite and it is just as it should be.
Should I be using a different procedure? An example of a string that would cause a crash for the string StringForTextFile would be:
C:Name of My AppSeries1ScreenNumber10.txt
If it was being written for the first time then no problem or if the 10 at the end was 0 to 9 then no problem also. I've also tried and originally had it set up where there wasn't an If File.Exists(StringForTextFile) = True Then statement. It just always used the same code whether writing or overwriting and I wasn't having a problem that I remember. For some reason I started having a problem recently and I put the alternate methods of writing in.
im writing the contents of a few arrays to a file using StreamWriter, and am having issues with the syntax of the format function. Tried reading through the help files to no avail, can anyone possibly explain the syntax to me?
View 2 RepliesIn 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 _

View 6 RepliesI am building an application that accepts input entered into textboxes, then checks the input for negative values, etc. before writing it to a file. If the data does not meet the conditions, a message box pops up letting the user know. The problem I am having is that after it checks the data and displays the message box, it continues to save the input to the file anyway. How do I make it only write to the file if all the data meets my conditions?
View 1 RepliesI am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.
CODE:
I have a simple application that use thread pool to read a file and input the data into a listbox. I want to be able to stop threadpool from running after clicking a stop button. How do I stop threadpool? Here is the code for my application below:
Imports System.Threading
Public Class Form1
Private Delegate Sub StringDelegate(ByVal text As String)
[Code]....
I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

View 1 RepliesI have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?
