.net - Process.Start Not Starting?

May 24, 2011

I'm trying to execute a 3rd party application, called from a .cmd batch file, called from a self-hosted WCF service. Like this:

WCF --> .cmd --> 3rd party app

For whatever reason, using the Shell command doesn't work fully. It will call the .cmd file, but the 3rd party app won't kick off (I know the .cmd is firing because I have before/after ECHO statements populating a log file). If I double-click the .cmd file from explorer, the 3rd party app will start just fine. So, I figured, maybe try something besides the Shell command from my WCF service.

So I tried the following code, but it won't kick off the .cmd file at all (echo statements not firing). What am I missing here?

Dim psi As New ProcessStartInfo("cmd.exe", "/C " & System.Configuration.ConfigurationManager.AppSettings("ExStream_CMD_File_Path"))
Dim proc As New Process()
proc.StartInfo = psi
proc.Start()
proc.WaitForExit()

The path in the app.config file is valid (just double-checked). Is there anything wrong with the above code?

Starting A Control Panel Process?

May 21, 2009

I'm using an electronic signature pad for one of my applications. The pad has a Control Panel file which handles it's configuration (image display, etc). I would like to know if it is possible to open the pad's control panel from within VB.NET. I've tried using Process.Start() but can't get it to wok, and I'm not sure if it is a problem with what I'm typing in, or if Process.Start is not what I need to use here.

Starting Multiple Documents In The Same Process

Apr 2, 2009

I am writing an application which needs to allow the user to select and open document files as a new process, edit them, then when they've finished backup the changed files automatically. For example, start a .doc file within Word or a .xls file with Excel What I wanted to do was use process.start to run the application and store the ProcessID returned in an array so that when the process finished, I could check all the files that were using that application for changes.

VS 2010 Starting A Process With A Command?

Dec 15, 2011

I want to launch System Restore through my program. I figured out the destination of this feature in Win7 is: WindowsSystem32control.exe sysdm.cpl @0,4

So I wrote this

Dim p As New System.Diagnostics.Process
Private Sub CreateASystemRestorePointToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

[Code]....

Problem is that it will not work if I have anything behind .exe And "sysdm.cpl @0,4" is vital for this to work, otherwise I just launch Control Panel, which is pretty useless for what I want to achieve.

So how do I include commands like those in Visual Basic?

Starting A Process In The Current Command Window In .NET

Sep 22, 2010

I have this in a VB.NET console application:

Dim p As ProcessStartInfo
p = New ProcessStartInfo(Environment.CurrentDirectory & "injavac.exe",ClassName & ".java")
Dim ps As Process = Process.Start(p)

This does run the java compiler on the file, but it does so in a new window. I want the output from javac to appear in the same console that is running my application. How can I do this? Perhaps there is another method for running commands in the current console? Or maybe I can supress the second console window from opening and redirect its output to the current console?

Win32 Exception When Starting A Process From An Application?

Dec 9, 2009

I have an application that starts one of two external CAD applications depending upon the extension of a file in a ListView. I have been able to start up the application to view the file selected without a problem. I also have a seperate print click event for printing the file that opens the viewer application in the background and prints the file. This works perfectly for one of the CAD viewers but when I select a file that requires the other viewer application to print I get a Win32 exception and an error message stating that the file is not associated with any application and it cannot be opened. This of course is rediculous as it opens fine in the "View File" click event that opens the viewer to check the drawing.

One rather strange observation is that the CAD viewer that does print the associated file will launch the other CAD viewer application (that is associated with the other file extensions) when the "View" click event is handled even though I had not incuded the code to execute the process to start the viewer for that type of file. I realize this rather convoluted and may lie in the ProcessStartInfo arguments that I pass to the application.

Here's a code snippet:

Private Sub PrintFinGoods_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintFinGoods.Click
Dim message As String = "No application is associated with file"
Dim source_exception As New Exception

Forms :: Starting To Get Back Into VB Programming?

Dec 21, 2010

I am just starting to get back into VB programming, and I'm looking for a more elegant solution to an application I'm developing for a production line.I have a series of labels with manufacturing steps. The background color of the steps needs to change to green as the process steps through. Right now it is working as it should, it just seems a little too much like brute force programming.

Right now I'm using a Select statement to change the color of EACH label. The first portion of the Select statement is below. With this method I have to do this same thing for each case.

Forms :: Input Starting And Ending Time

Nov 2, 2009

I want to make a very small program where the user inputs a starting time and an ending time that is in "clock time (?)" and the program converts it to total minutes in one box and a decimal total in a second box. I have 4 textboxes, 2 are masked text boxes (military time) for input and two are not, for output and the math is coming out weird.

If I put a start time of 0925 and an end time of 1015, the results I'm expecting would be 50 total minutes and .83333 total as a decimal. I don't think I'm converting the textbox input correctly as I'm not getting anything near that. I am using a button to calculate and another to clear the boxes, just FYI. Also, I'm not sure what to do about any times that span the noon hour except to use an absolute value.

Public Function Time()
Dim StartTime As Double
Dim Endtime As Double
StartTime = txtStart.Text
Endtime = txtEnd.Text
txtDecimal.Text = (Endtime - StartTime) / 60
txtMinutes.Text = Endtime - StartTime
End Function
