.NET Read Standard Output?
Jun 30, 2011
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 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?

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 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 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...)

I'm probably missing something really simple or trying too much at once but it's 16:30 on a Friday afternoon and my head is wrecked Basically, I'm trying to build an application that takes out put from a database query as XML and uses XSL to transform it into HTML which is then displayed in a web browser controll on another form.
I thought I break it up into pieces so I decided to just create an XML file and an XSL stylesheet and read this into the web browser control but all I'm getting is <HTML></HTML>

I've been trolling for a long time now and have decided to register as I finally have some time to start jumping into VB. The last time I coded VB, the current version was VB 4. I've been out of programming for a good while now and considered myself a beginner (tutorial example coder haha).
My question is: Where is a good place to start learning VB.NET?
I know it's an often asked and answered question - but let me give you a bit more information so more specialized replies might be given.
I'm in INFOSEC/COMSEC and would like to (eventually) develop a program that contains a DB of information that is read by the application and saves input information into a DB (encrypted) as well. The program will be a 800-53 C&A control assessment program; used for tracking system compliance for federal information systems. I would like to be able to develop such a tool to make my life easier at work instead of using Excel spreadsheets to track everything.
I would like to learn:
- Input / Output methods and validation (for secure coding)
- Read/Write DB Encryption (RSA or other 128-bit) for user input information
- Ability to generate PDF reports from the primary keys and data sets from the above DB
My goal is to create a program that allows a user to install the program, setup a 'master' account that a serial/key has been generated for - that master account is then allowed to create new projects (progress saved in DB). A project asks the user certain questions pertaining to information systems and takes the input and saves it into the DB (encrypted). When the assessment is completed, I would like the program to be able to generate a PDF report from the DB (from a layout template I created).

1) Can anyone post a link or tell me the differences between these versions of VISUAL STUDIO please? >>
Standard, Professional, Team Suite, Team Foundation Server Standard & Team Foundation Server WorkGroup Edition
2) I imagine Team Foundation Server WorkGroup Edition is the most expensive and therefore has the most functionality?
3) Are there any others I have not mentioned?

I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next
not giving me a debug output?

So, I don't want this to get into a flame war between C# and VB.NET developers. This is purely from a standpoint of a development department going forward. We've been a VB.NET company for years, but that was mainly due to who we've hired. That requirement has fallen off the wayside as of late, as we've pulled in 2 guys who specialize in C#. I used to be a C++/C# guy before converting to VB.NET for this company.
So, to everyone who has to deal with this whether on a hiring basis or a maintainability basis: how do you handle standardizing languages of choice going forward? I'm inclined to make a push for C#, as that'll make 3 solid C# developers here. But just curious what everyone's thoughts on this are.
