Use WriteLine To Write One Line, Then Skip To The Next Line And Do It Again?
May 24, 2011I've already used arrays and a random number to generate a sentence with the pattern KLAC, but I need to write this to a text document and then do it again. I have succeeded to write the first sentence, but the second will not register.This represents essentially everything I've tried. (I haven't included the arrays because they're pretty long.)
repeat:
Dim rndNo As New Random()
Dim chosen_aword = aword(rndNo.Next(0, aword.Length))

.net - Find Location Of A Short Sequence Of Bytes In Byte Array?
Jan 15, 2011How can I efficiently find the location of the first instance of a four byte sequence within a byte array? Is there something more efficient than looping through the whole array, or a built-in method?
I'm searching through a byte array for a pair of CrLF. I can't convert it to string for an InStr first because I need the position of it in the original byte array.
I am trying to figure out the location of this, as it delimits between a string portion and a binary portion, similar (well, exactly like for this part of it) to an HTTP header. There is a string portion, and two CrLf before the content begins.
Command Line Argument: Check If Correct Command Line Or Exit App?
Jun 6, 2012I have beginner skills using VB (am using the Express edition to learn). I would like to know how to set up a conditional statement in a Windows Form (WF) app that would check if a specific command line has been passed by another separate app that launchesthe Windows Form app using command lines, and if not passed, then the Windows Form app would shut down (exit, close).So far, I can use:
For Each s As String In My.Application.CommandLineArgs
If s <> "xyz" Then

Make Textbox1 Skip A Line?
Apr 30, 2009In button1 Keyup I want to be able to make textbox1 skip a line.How would i do this. I tryed
Private Sub button1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles button1.KeyUp
If e.KeyCode = Keys.Enter Then
textbox1.text = vbnewline
End If
End Sub
I would also want to know how to make it when I push the button2 it will undo the letter I just did
Private Sub button2_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles button2.KeyUp
If e.KeyCode = Keys.Back Then
textbox1.undo 'this will just undo the whole text I just did
End If
End Sub
Why Excel Read Skip First Line
Aug 24, 2011There is a program that reads an Excel file using OLEDB and converts it to a tab delimited text file. This loop handles the conversion.
While reader.Read
Dim count As Integer = 0
Try
While (True)
temp = reader(count).ToString + ControlChars.Tab
output_file.Write(temp)
count += 1
End While
Catch ex As Exception
output_file.WriteLine()
End Try
End While
Not the most elegant code for sure, but it reads in each cell one by one, then throws an exception at the end of the row to write a newline. The only problem is that it skips the first line of the Excel document.
VS 2010 - Sequence Of Commands To RS232 - How To Sure Command Is Received
Dec 20, 2011I write in VB2010, the software should work with the external hardware via RS232, the thing is when I send a command to the external hardware I have to wait for a reply from the device that command was received, just after I got the answer I want to continue send another command, I have a long sequence of commands i'm supposed to send, but I need to know for sure that the commands were received before I go on to the next command. I did the following code, but I think the code is not effective, because sometimes I do not get an answer and then the whole sequence commands destroyed. Maybe you can help me optimize the code?

VB2008 Send 00h To FFh In One Byte Using SerialPort
Feb 1, 2010peoples The User of my application will enter Hexa values in text boxes (00h to FFh). I need to send these values through the serial port, but so that EACH text box with values 00h to FFh ONLY generate ONE transmitted byte, exactly the value placed in the text box.
Just found examples of this application in VB6, using the following command:
MSComm1.Output = (Chr(Val(txtText1.Text)))
In VB2008, you use the component "SerialPort", and one of the methods for transmitting data to the output buffer is "Write". So I did it this way:Dim As Integer ValHex

Write Binary File In Sequence With Listview?
Dec 5, 2011Write binary file in sequence with Listview.I'm loading data from a *. bin file in a listview to modify.Now I want to write listview data in the file.The start offset is 1036.The sequence of each data block is 228 bytes.The number of times to repeat the sequence is 8011.There is more information ... but I put these 3 sample.In the first data block to these lengths are Name Offset 1036 +50 (name space long is 22 bytes)Age Offset 1036 +60
Nationality Offset 1036 + 62
I suppose that before writing the data in the file would have to convert the data item and subitems in hex or byte.

Feb 24, 2010I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")

My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.
Send Command To Command Line From Windows Form Application?
Mar 11, 2010I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).

Command Line Program To End Before Moving Onto The Next Command In Loop?
Feb 4, 2011I am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

Possible To Write A Byte Higher Than 255?
Sep 12, 2010We were currently working with our thesis regarding file compression and selected LZW compression. So far, we know how to work on it but we were stucked on how to write a byte.LZW uses 256 and up for the code table because 0 to 255 was used for a single byte.url...Our problem was we don't know how to write a byte higher than 255, s it possible, and read it as it is? Or, different way on how to do it?
View 1 Replies.NET - Pass Command On Command Line?
May 29, 2012I am struggling to pass a parameter to a VB.NET application via a Windows scheduled task. It works perfectly in Visual Studio (passing a command line arguement via project properties).If I am calling a VB6 application, then I will supply the following parameters and it works:
Run: c:progra~1TestTest.exe TestParameter Start In: c:progra~1Test However, if I supply the same parameters in VB.NET, the program throws an exception when it tries to create an instance of a class in the Form.Load: System.NullReferenceException cannot create instance of object.
I have also tried the following:Run: c:program filesTestTest.exe TestParameter Start In: "c:program filesTest" This time the status of the scheduled task changes to "cannot start".What is the correct way to specify command line parameters in a scheduled task for a VB.NET program?UPDATE I found the solution on this web page:[URL}.. I am still confused as to why the program would not create an instance of an object when I used the 8 bit paths (i.e. progra~1)
