Redirecting The Standard Output?
Jun 16, 2010
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.

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.)

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.

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?

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?

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 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.

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...)

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.

Currently I have a button which on client click, runs a jquerry function that changes the text on a (hidden to the user) label, and then clicks a second (also hidden to the user) button. This second button then runs an ASP.NET function whose last command is to redirect to a second page. The reason I needed to do this, is because I store the value of the label (which is dynamically assigned according to a database) into a session variable BEFORE redirecting to the second page.
This method works perfectly on Chrome and Firefox. Nevertheless, it doesn't seem to be redirecting in IE. It does, however, store the session variable (i.e. the sub routine that handles the hidden button's click event IS called).
Edit: I've tried clicking the hidden button myself, and it works fine, so it is definitely something with the postback from the first button interfering with the subroutine called from the second one.

In my project, I got a page that creates guest users for a number of products chosen.Basically you tell the application how many users to create for each product you choose.When you click 'Save' I generate the guests, save their username + password (before encryption) in a csv file that I transmit at the end of the process, and finally redirect the user to the index page.The problem happens at the file transmission and the consequent redirection to a new action:
Private Sub DownloadCsv(ByVal csv As List(Of String), ByVal filename As String)
Dim sb As New StringBuilder()
For Each Str As String In csv
[code]....
What's happening is the page transmitting the file to the browser and never doing the redirect that follows.I read a bit on the matter and found out that once you add an Header to our Response object and Write a file, it will automatically close the Response. If I'm wrong, please correct me.How can I make it possible to transmit this file after the user has being redirected to the Index or Redirect to the Index after he either saves or cancels the file download?

I have an ASP.NET form with a cancel button that is supposed to, after confirmation from the user, redirect them to another page. I'm using javascript for this. It works fine in a simple HTML page, but apparently something is interfering with it on the .aspx page. The popup message works perfectly, but clicking "Okay" does not take you to another page. I have tested the if statement and it is working correctly, the only thing it won't do is leave the current page. [code]...

I'm using javascript to send a array to my code behind so it can be saved. And also to redirecting the page to the next dataset.
function ChangeMonth(utcDate){
PageMethods.javaGetArray(colors);
alert("saving...");
window.location = "./transport.aspx?date=" + utcDate;
}
This works perfectly when there's an alert in between, the saving and the redirect. If I delete the alert it just redirects without saving.
