Redirecting Standard Output From A Process (msxsl.exe) To A String
Nov 24, 2010
I am writing a command line application in VB.NET. This application is calling another one, msxsl.exe, to run an XSL transform. I am using the Process class to do this:[code]What I want it to be able to display the output from this process to the console of my application. I have read several posts explaining this method, but it does not seem to work in this case. The output is an empty string.[code]I have verified that if I run the msxsl executable on its own (i.e. running "msxsl.exe base.xml test.xsl -o styled.xml"), it displays output on the command line. What am I doing wrong?I should note that the msxsl process is currently failing due to a malformed XML file. It is displaying this error message:[code]This is exactly the type of thing I want displayed in the console of my application (or, eventually, a log file.)

I am having trouble redirecting standardoutput and standarderror from a command line program that dumps a lot of numbers to the screen. I've looked through a lot of similar posts and think my code matches what it should be doing (asynchronous reading of the data with appropriate invokes for writing to the log text box) but it still just hangs the application until my p.WaitForExit times out. Once it times out and I kill the process, a chunk (but not all) of the data is written to the textbox in from the OutputDataReceived event handler. Any ideas what is going on here? I've seen some posts regarding buffer size, but that apparently is fixed (i.e. I can set a buffer size of 1 and receive every char). Below is my function to execute the process and two relevant event handlers.
Private Function ExecuteWallGen() As Boolean
Dim bResult As Boolean = False
Dim szExec = Me.ExecutablePath & Me.WallGenExecutable

I am trying to redirect the output of a c program which generates output in the console. I can redirect the output once the process exits. But is there the way to redirect the output as and when there is some output in the shell window? I require this to make it understandable that the program is running and since different steps of the c code may take, say 10-15 minutes to run.

My application periodically starts console programs with process.start. I need to monitor the output of the programs in "realtime".
For example, the program writes the following text to the console: Processing...............
Every second or so a new dot appears to let the user know the program is still processing. However,... until the programm outputs a CR/LF, I am not able to retrieve the standard output of the program (while it is still running).
What can I do to get the output in realtime for - let's say - piping it into a database for instance in VB.NET?

Dim myProcess As New Process()
Try
Dim s As String
myProcess.StartInfo.UseShellExecute = False
myProcess.StartInfo.FileName = "flac.exe"
[Code] .....
The AppendText runs and works on an initial run of the exe, but the problem is that not all output is redirected. when using parameters I get no output from the stream, but running flac.exe at the command prompt reveals output of course. Does anyone know anything about redirects and how to make the above code redirect ALL output from the exe?
flac.exe is a lossless audio codec utility. I am making a frontend for it.

Ok, so I've got this code and what it does is it redirects the standard output from the console (Process) and puts it into the textbox (consoleOutput). It seems to work really well but the only thing wrong with it is that it redirects, or enters, the same entry into the textbox 2, 3 or sometimes 4 times! I have looked through my code several times and can not seem to find out what is causing this. Lower down you can see my code so far for the program, and a screenshot of the program while it is redirecting.

I try to redirect a robocopy job to a textbox. If I write the complete output after the job finishes, all is displayed correctly.
Code:
myProcess.StartInfo.FileName = "cmd.exe"
myProcess.StartInfo.Arguments = "/C " & Chr(34) & cntCommand & Chr(34) & " && exit"
myProcess.EnableRaisingEvents = True
myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden

From my application I need to run a command and parse the output. I can do this with no problem but I don't want the command to be displayed. I hoped WindowStyle = ProcessWindowStyle.Hidden would work but it doesn't. Take the sample code below for example. It works fine but the command window still visibly opens and closes very quickly and I need it to never show its ugly face. How can I fix this?

I wonder if it is possible to write and capture errors when running a script to PowerShell.In my case I am using the following code:[code]' add an extra command to transform the script output objects into nicely formatted strings' remove this line to get the actual objects that the script returns, for example, see the script "Get-Process" returns a collection.[code]

I use the following code to read the standard output from a command line application from a main winforms application, and then I use the BeginInvoke code to update a textbox with the status. What I am not sure about is if I can have a smoother process. The code loads up about 10 to 20 text inserts, and those are all seen at once... not a smooth process where each status is updated. Any thoughts on if the reading of the standard output and/or the beginvoke code could seem more smooth to the user?
Delegate Sub UpdateUIStatusHandler(ByVal StatusMessage As String, ByVal JobName As String, ByVal Direction As String)
Dim ProcessJob As New ProcessStartInfo(GSyncExe, RunJob)
ProcessJob.UseShellExecute = False : ProcessJob.CreateNoWindow = True : ProcessJob.RedirectStandardOutput = True : ProcessJob.RedirectStandardError

i have a form app that needs to get the output of a console app in real time.or as close to it as possible.[code]that is my code so far, and it seems to work great for everything other than the actual console app i need it to.when i use it on ping commands it comes up in my text box perfectly.when i use it with my console app (which i don't have access to the source for) it outputs nothing until the app closes, sometimes.it depends on the arguments given. i am 100% sure it is the way the app is written but there is nothing i can do about it.so is there any way to get the desired functionality some other way?

I am working on a frontend. I use Process.Start("file.exe", "arguments") to start the process.
Is there a simple way to get output by the process returned in a textbox?

I am trying to write a VB .NET program that runs a Perl script and reads and uses the standard output. I'd like to be able to handle each line separately as it is printed, and update my program display accordingly. Here's some code I have "written" (read: "mostly copied off the internet"):
Private WithEvents pscript As Process
Private Sub myProgram_Load(sender As Object, e As System.EventArgs) Handles Me.Load
pscript = New Process()
[Code]....
This works with one problem: the program waits until the test script has run to completion, and then fires several OutputDataReceived events one after the other. This means that when I make it use the real script, it's likely to do nothing for as much as several hours, and then have to deal with, like, 5,000 events at once, despite the fact that stuff was being printed at fairly regular intervals throughout that time.
Is there any way I can make it deal with each line of text when it is written, instead of all of it at once at the end?

I want to launch a file from a VB program and capture the output of that file in a text document.Here's an example:Process.Start("systeminfo.exe > Data.dat")This doesn't work. I get an error that the file cannot be found. I've tried using Shell instead of Process.Start. I've also tried replacing systeminfo.exe with a variable and replacing the redirect portion with a variable.The ultimate goal is to get the text file e-mailed. So, if it were possible to output to the Clipboard, then paste that to a file or directly into an e-mail client that would also work.

I usually use standard button and do the settings like causevalidation etc if required.
i decided to use toolstrip and inserted some buttons but end up that it doesn't do the validation for control and also doesn't call leave event of textbox control.
so my question is, anyway to use regular button functionality for toolstripbutton or there is a way to add regular button on toolstrip.

The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly
m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.

I've been working on automating our build processes and wanted to come up with a painless way to run unit tests on a regular basis. To that end I've thrown together a simple app that examines the project files and prepares a list of solutions to test. The prototype works in that the tests are executed with the expected results, but as soon as I try to redirect my output the app bombs on the Process.Start call, complaining that a file could not be found.
I've tried several iterations on what I've seen done elsewhere, including several posts here, but I have yet to get this to work properly.
This works:
Private Function WTF(ByVal aWorkingDirectory As String, ByVal aFileName As String, ByVal aArguments As String) As Boolean

I am trying to add a TabPage containing a UserControl to a TabControl at runtime, because the number of TabPages to add are determined at runtime.
The UserControl (objDataInfo) is just two Textboxes, two labels and two Radiobuttons, nothing too exciting...
The TextBoxes have their Anchor properties set to Left, Up, Right so they scale with the width of the usercontrol.
The TabPages are added in the constructor of the form, which takes the number of tabpages to create (n) as an argument:
vb.net
Dim cList As List(Of objDataInfo)
Public Sub New(ByVal n As Integer)
[Code]....
So... How can I get the standard BackColor of a standard TabPage?
(I tried leaving out the usercontrol all-together, but the TabPage still has a gray background...)

I'm suppose to end up with a label box with my name spelled out in it using string manipulation. This is suppose to happen using the concatenated string to output the name into the label box. I don't have any error codes but I also don't have my name in the label either. [code] "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. [code]
