Winforms - Writing To Console And Stdout?
Jul 25, 2010
I have a winform app that is writing to console and it seems to work well. I'm using this code:
AttachConsole(-1)
Console.Out.WriteLine("Hellow world")
FreeConsole()
The question is:If I run the app's exe file from command line, and try to redirect the output into a file. It doesn't work.For example:
C: > myapp.exe > c:output.txt
I still get the output to console screen (c:output.txt file is created but empty), but I want it to to be saved into c:output.txt.

I have an application with a String variable that repeated gets a Date from a database, does something with that field, then goes onto the next row. Is there a way I can send send out some debugging information to the stdout console so I can debug better/view the progress of the program?

I need to figure out a way to programatically determine whether code is being called from a console application or a WinForms application (or even WPF). The scenario is, a .net DLL library needs to know what kind of application is calling it. Is this possible?

I am working with a console application for VB 10.
How can I replace data that I have already written with:
Console.Write
Or how can I write on a specific point: e.g. 100 lines, 100 chars left
In the same way that a program such as wget has a loading bar that does not keep getting replaced every time progress is increased.

I have Visual Basic 2010, can you tell me how I could simplify this code without using the last IF statement? In other words, have console.beep when form2 comes up, but with out adding the extra line?What would an easier way to write this be? I mean instead of writing the separate if statement for the console.beep?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text = "valentines" And TextBox2.Text = "day" Then Form2.Show() Else MsgBox("That's Not It Theresa!")
If Form2.Focus = True Then Console.Beep()
End Sub

I have a multi threaded app that writes log to file. occasionally, saving fails using this code:
Friend Sub SaveToText(ByVal FileName As String, ByVal Text As String)
'// create a writer and open the file
Dim objLock As New Object
SyncLock objLock
Dim tw As TextWriter = Nothing

The error message I get:
The process cannot access the file 'error.log' because it is being used by another process.

I am writing an application in VB .NET which calls external executables (written in C++)and passes them some command line arguments. What I need to do is read back their stdout outputs inealtime , i.e. as they run.I am currently using the ProcessStartInfo class and setting the RedirectStandardOutput property to true and reading it back in from a StreamReader. However, I cannot read this back in realtime. Once the process finishes, the StreamReader will allow me to

detect whether the current application is a console or a winforms application.The reason that I want to do this is that I am developing a library with a global error handler in it and I need to know what type of application it is in order to be able to subscribe to the appropriate exception event.Obviously I could get the user to pass in a parameter specifying what type of application it is, but I would rather deal with that automatically so its all encapsulated from the user of the class.

I'm trying to adapt a VBscript that runs the QWINSTA command against a text file I've defined as an array and displays the results in a text file.after looking at numerous examples on Stack and other sites this is my latest iteration, that displays everything except the STDOUT, which is really what I'm after, not sure if it's an issue with how I'm calling the command piping the output or what. I'm also passing two variables as arguments to complicate matters :)
The Text file that stdout is piped to is empty after the FOR Loop completes I may be going the long way about this, most of my past experience with this is in BATCH

This code executes "handbrakecli" (a command line application) and places the output into a string:
Dim p As Process = New Process
p.StartInfo.FileName = "handbrakecli"
p.StartInfo.Arguments = "-i [source] -o [destination]"

I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

I have a console application I'm using to run scheduled jobs through windows scheduler. All the communication to/from the application is in email, event logging, database logs. Is there any way I can suppress the console window from coming up?

I am currently working on an application, where I am using a console application, that will set up the application prior to the main form is run. This is no problem I've got that all working perfectly, the only problem I have is that the console is showing while the application is running, I was wondering whether anyone knows any way in which I would be able to hide the console before it gets shown to the user.

I am trying to send/print/write all possible ASCII codes (0-255) to another console-window application. From my application I would enter the name of the "receiving" application and the comma seperated hex values that should be sent/print/written to it. I have used AppActivate to select the "receiving" application and then have used sendInput and send.sendkeys to attempt to send the desired ASCII value. However, these appear to have limitations on values greater than 127. I need to be able to send all 255 values.

How do I get the console from closing immediatley upon opening in a Console Application program? I have all of the code written but when I run the program it pops up the console window and then immediatley exits so I am unable to read what is in the window to see if my program is operating correctly. This is the first time I've ever used a console window so I don't know where in the code I would need to put "whatever it is" I might need to put to keep the window open until closed by the user.

It sounds confusing but it's not really. What I need is basically a way to emulate the console style text, without using a console. What I'm really doing is trying to do a matrix effect on my form background, by drawing symbols and moving them, alternating their colors (see this video for what I mean).
Is there a way to do this effectively with a timer and a draw event, with the timer calling the draw event and changing the intervals?

Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).

I am needing to pass options to a windows mobile console app so I can pass variables.I have that working fine, but have found out that my options need to be a little more descriptive as I will probably have 20+ in the end. I am wanting for example myapp.exe --username bob --password myp@ssword --domain ads.microsoft.com --SSID wirelessnetwork --authentation peap --securitymode wpa1 etc Right now my code just goes by charcter length that limits me to the same length of option. I want to have longer descriptive options but need a way to allow longer option lengths.

I want it to check for my DLL in the same directory. If it's not there, the application should exit gracefully.I thought this code would work but it still crashes without the DLL. Although it will not crash if I comment out everything after the IF statement.
