VS 2010 Process.StandardOutput Not Matching?
Dec 26, 2011
I'm running a program and reading the command line output, and, when I compare the output I get with the actual output of the program, I'm quite shocked to see that it doesn't actually match up and, sometimes, the text won't even display at all until after the entire process is done [despite using the Asynchronous methods].I'm not sure if I'm doing anything wrong here...I can post the code [it's a rough translation from VB.net to C#, which I can easily translate back], but is there anything I can actually do to fix this issue

I run a process (ffmpeg) in a backgroundworker and need it's output to calcute remaining time, estimated filesize etc. but I don't get any output from it. Here's the code used in the DoWork sub
Dim p As New Process
pback.WorkerReportsProgress = True
pback.WorkerSupportsCancellation = True
Dim tmpopts As MyOpts = DirectCast(e.Argument, MyOpts)
[code].....
The process runs and creates the file I'm expecting. I just don't get any output from it while doing it's work. The debug MsgBox shows one time and contains nothing but if I run ffmpeg without redirection in a shell it's outputting a new line every second.

I wrote a gui for a console app, wanted to captaure console app standarderror and standardoutput in the same time. I write a code, but it's not executed in the same time. I searched msdn and found that using DataReceivedEventHandler can be asynchronously collect the redirected StandardOutput or StandardError stream output of a proces. But I dont know how to apply it to my code. please help me. i wanted to collect standardoutput and standarderror and append it to a textbox. here is my code,As far as I understand, I have to read one stream synchronously and one asynchronously to avoid deadlock situations.But now it's not output in the same time. having delay issue for standarderror.
Dim start As New ProcessStartInfo("C:WindowsSystem32java.exe")
start.Arguments = "-jar" + " " + "args"
start.CreateNoWindow = True

I have seen countless examples of reading standard output from command line applications which print text to the screen and one can read that back into the application as a string. I want to read the binary data back that is written to standard output from something such as image magick's convert program. What is coming back is an image, not a text result or error code. Is this possible? I have been looking for ages but found nothing that makes sense.

In javascript I know you can put for instance if date= "2010"* which would do the if for the string if it starts with 2010 but it doesn't matter what comes after that.

Please help solve the problem.First, let me describe what I want to feature me of the problem.I Function SPLITyahoomessage () to intercept the statement, the statement should not be captured through the interception.Here I use x () array to the breakpoint.But I say there are two windows in the pm 10:10 swept the first window of the sentence recorded in x (0) in Then x (1) record from the second window of the sentence.Here is a very strange x (0) memory from the sentence.Here are the features I want to achieve
It will break out in the interception of sentence in accordance with the procedure. But the second window x (1) I gradually during the scan, I found that x (1) had memorized the sentence re-enter
SPLITyahoomessage () in the time x (1) into nothing.

I need an extremely simple regex pattern that matches anything within square brackets [].
Example:
This is a [test] text with [some] [examples].Required results: [test], [some], [examples].I don't want to get rid of the brackets, they should be included in the result (that should make it easier, right?)
If possible I'd like to exlude results that have whitespace in them, so things like [this string] should not be matched. If that gets too hard (probably not, but hey I can't even manage this :S) then I don't really mind, I can always check if the result contains whitespace myself.
I tried a lot of examples I could find online and ones that I could think of myself but none work. Note: I've been testing with the Visual Studio Find dialog (checking to use regular expressions obviously), maybe that's where the problem lies, because I don't really understand why some of these don't work...
Anyway, first thing I tried was simple: match the two brackets and one or more characters in between (that should be a +, right?)

I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

I am using Vb 2010 I am trying to make a matching game. My problem is I have picture boxes 16 to be exact. I want each one to randomly go to a certain place I have already picked on the form. That means that I have 16 places already picked and I have made point variables for all 16. I can not seam to randomize the picture boxes to be placed in only those 16 locations.

I am working with saving and deleting images. What i really want to do is check and see if an image exists in the destination folder and if it does automatically overwrite it. i couldnt figure that out so i figured i would look to see if the file was there if it is Delete it then write the new file..The issue is i keep getting this error.The process cannot access the file "FileName" because it is being used by another process.

I am trying to completely intercept a console application, that is, grabbing it's output, and inserting the input. So far, I can pretty much grab the output, and input is completely perfect. However, it will not show the "prefix"/"question" of the console's output, until you send some input. As an example, when hooking to the CMD.exe console. When you regularly start it up in Windows, you get something like this:

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

I want the program I am making to show the cursors position on the process it is attached to. Sorry if this is a lot to ask for. Can you tell me how to.
1. Make a drop down menu with the list of process.
2. When i click on one of the processes, my program attaches to it.
3. When I move the cursor over the process, my program tells me the co-ordinates of the mouse on the process.
4. When i press F3, Timer3 Starts.
5. Make the mouse move to a co-ordinate on this process.
If it is too much to ask for, can you just tell me how to do 1 of them and hopefully someone else will tell me to do the others.

I am working on an application that needs to launch Microsoft Word, and then resume when the user closes Word. The code below should work, but it does not. I get an 'object not set to an instance of an object'
1 Dim pInfo As New ProcessStartInfo
2 Dim P As New Process
3 pInfo.FileName = "C: estLLR.doc"
4 P = Process.Start(pInfo)
5 ''# Here is where it goes bad
6 P.WaitForInputIdle()
7 P.WaitForExit()
I put p into the watch window and it shows a a system.diagnostics.process in the watch after line2, but after line 4 it return to NOTHING. The process launches, but I can not monitor it any longer with lines 6 & 7. Is this a 'limitation' of Visual Studio 2010 or am I making an operator error? The MS Help does not show process available in the 2010 version (it is in Visual Studio 2005 and Visual Studio 2008).

Basically, I am just trying to close the thread/process after it's done.
Private psi As ProcessStartInfo
Private cmd As Process
Public Delegate Sub InvokeWithString(ByVal text As String)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim psi As New ProcessStartInfo("m7.bat")
[Code] .....
I am trying to close the thread so once it's done, it closed for good and my form is closed as well. I tried Me.Close() which results in: "Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on." Error.
Me.Invoke(New InvokeWithString(AddressOf CloseME), e) - Results in parameter mismatch error.
However, things like Msgbox("Done") works perfectly.

im trying to start a process within vb.net as an administrator. I have succesfully impersonated an administrator from within my application, however when I try to process.start to access a UNC path it says login username or password invalid. This is not true because im running as the user who has permissions to access that unc path.
I was able to work around this, by using shell() instead of process.start(). However, with Shell() you can not specify a username and password, so I have to use the runas command. However, shell calls for runas, but runas requires you to enter a password in order to proceed to call the program your requesting runas to run. How can I programmatically enter the password into the runas.exe process as if I entered it manually.
If there is a way to implement this using process.start() instead of shell() please let me know.
This is what I have so far.
