C# - Fixing CA2122 With Process.Start
Mar 15, 2012
In an application we can output a report as a csv file and load it up similar to the following code:
Process.Start("C:MyReport.csv") ' Not real path
When running code analysis it produces the following error:
CA2122 Do not indirectly expose methods with link demands 'Form.Function(Definition)' calls into 'Process.Start(String)' which has a LinkDemand. By making this call, 'Process.Start(String)' is indirectly exposed to user code
I have seen somewhere to mark the assembly with the SecurityTransparentAttribute, does this just suppress the message? If so this is not what I would like. Is there another way of opening the file that would circumvent this message without suppressing it? I would ideally like to avoid Excel automation if I can as Excel is not used anywhere else at the moment.

I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

Visual Basic 2010 - Net Framework 4.0 Client
I have an application (application #1) running with Administrator privileges on Windows 7.
I want application # 1 to start another application (application #2) without Administrator privileges so application #2 is running as a standard user.
Is there a way to do this? I have been using Process.Start.

Here's what I currently have:
[Code]...
I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.

My app starts an On-Screen Keyboard process like this:
Dim PID as System.Diagnostics.Process
:
PID = Process.Start("C:WindowsSystem32osk.exe")
:
[CODE]...
It seems to work 90% of the time. However, sometimes the PID.Kill() fails because it says the process already exited. At this point the OSK is always still there on screen. Yes, I know my code should be testing to see if the process is still running before trying to kill it, but given that the OSK is still on screen..

I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

it works perfectly during run time. but after i deploy to server.... this code did nothing, it did not call out this process

I am writing an application that in the end needs to execute another executable at some point, the problem is that the executable has dependencies in the directory it runs in that are required to operate. When I use the Process.Start to run the executable it errors out because it's looking for the dependencies in my applications directory.
I tried the startInfo.WorkingDirectory option but that didn't seem to do it either (not sure if I did it right) - here is how I used that:
Process.Start("my.exe").StartInfo.WorkingDirectory = "C:Test"For the life of me I cannot find how to set the "Start In" directory. I looked everywhere, so unless it's under a different name, I'm at a loss.

I am trying to create an app that will perform actions on specific times (much like the Windows Task Scheduler). I am currently using Process.Start() to lunch the file (or exe) required by the task. I am initiating a process by calling a file (an .mp3) and the process starts WMP (since it is the default application), so far so good. Now I wan't to kill that process. I know that it is normal behavior for the Process.Start(string, string) to return nothing (null in C#) in this case. So I am asking how can i close WMP when I called it through Process.Start(string, string)??

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?

Is there any way I can install a global hook or something else on the start of external process. WH_CBT hook, as it appears can only intercept events for processes that have windows, but what if I want to intercept the start/stop of a windowless application or a windows service? Is there any way to do it using .NET?Generally, I want my application to receive a notification of some process being launched knowing only an executable name.Presently I simply use a timer to iterate through running processes, but I wonder if there a better way to do it?

I know how to launch a file or executable in VB .NET 2005. The file will launch and execution in the code continues immediately.
Process.Start("MyProg.exe")
But what if I need to start the program, wait until it finishes executing, read the exit code that it sends back, and take some action based upon the action code? How do I do that?

I am trying to run a process started with the following VB statement.
The process will start fine with the proper admin ID that I specify. I have verified this by starting a CMD shell and batch files. They all show the user is my local admin account. However, if I try to run defrag or chkdsk, both commands tell me that I do not have authority to run them. Even though the processes are running under the admin account (shown by Task Manager).
The program is compiled on a Win XP SP3 machine (32-bit) using VB Express 2010. The executable seems to work fine on XP. But when I copy the .EXE file that it generates to my Windows 7 64-bit system, I get the above problem about it not having authority to run these two utilities.

I build a class library (dll) with a form in it. Now i start the dll : Dim myDLL As New ClassLibrary1.MyFirstDLL(). The problem is that this dll starts but not as a separate proces i also dont see it in the taskmanager. what i see is that when i start the dll from my program, my program start using more cpu/memory. The whole idea behind a dll is that it dont consume memory of the process that calls it. So how can i start the dll as a new separate proces but still be able to send variables to this dll. (i also created a whole new proces but then i can not send variables to it)

I'm trying to start the process Store.Client.UI.exe which is located at: "C:Program FilesIntelIntelAppStoreinStore.Client.UI.exe", or "C:Program Files (x86)IntelIntelAppStoreinStore.Client.UI.exe" for 64bit like me, so I use the code:
If My.Settings.instpathtype = 86 Then
Process.Start("C:Program FilesIntelIntelAppStoreinStore.Client.UI.exe")
Else
Process.Start("C:Program Files (x86)IntelIntelAppStoreinStore.Client.UI.exe")
End If
Where my.settings.instpathtype is whether the computer is 64 or 32 bit. But when I run it, it doesn't run Store.Client.UI.exe for some reason. When I go into Explorer and type "C:Program Files(x86)IntelIntelAppStoreinStore.Client.UI.exe" it runs Store.Client.UI.exe.

I'd like to have a function in my program that waits for a process to start, and once it does, it executes the code. Id like to have a form of 'buttonless messages box' or 'splash screen' waiting saying "waiting for process to start..." and once the process starts, a message box will pop up saying "Process has started!".
I was thinking of having a timer with a low delay constantly looping to see if the process exists, but that would be a little rough on the processor, no? Also, how would I accomplish the 'buttonless messagebox' that automatically closes once the process is found?

I have a problem with an App I am writing that lists information about various media on your computer and lets you launch it right from the app. My problem is, when launching an intensive process, like a game for instance, it is desirable to shut down the app to not hog precious resources. Here is the code i have so far...
[Code]...
This code works fine, but for one small detail. The app exits before the desired process starts, thus cancelling out the process all together. My question is, how do I get the app to wait for the process to start before exiting?
