I'm creating a sub that will run a batch file, and then delete it when it has finished.[code]...
This causes the program to immediately delete the batch file before it can run. How can I break it up so that it won't delete the batch file until after it has finished?
How can be find out which file is going to delete when, user provides command like DELETE or SHIFT + DELETE or by programmatically gives DELETE command. Well I know about FileSystemWatcher Class, but this class doesn't provide information before delete...
I have an application that that uses process.start. It works fine on my development machine...but not on an installed machine....at least not for a local file. The following illustrates my problem...the reference to the url works fine and every time. However, the reference to the local file may work the First time but on any following attempts will close the application with a WindowsApplication1 error. Since it can find the file occasionally it is not a file problem.
I want to launch a file from a VB program and capture the output of that file in a text document.Here's an example:Process.Start("systeminfo.exe > Data.dat")This doesn't work. I get an error that the file cannot be found. I've tried using Shell instead of Process.Start. I've also tried replacing systeminfo.exe with a variable and replacing the redirect portion with a variable.The ultimate goal is to get the text file e-mailed. So, if it were possible to output to the Clipboard, then paste that to a file or directly into an e-mail client that would also work.
I'm using System.Diagnostics.Process.Start to open a file using a string stored in a SQL datatable. It works absolutely fine as long as there is an application on the local machine associated with the file type. If there isn't an association, what happens is the "Save as" dialog box pops up. What I'd like to happen is to just bring up a message box or some other prompt that tells the user what the problem is, and to contact the helpdesk. Some users will be confused if they see a "Save as" dialog box, I think.
I'm trying to open any file using Process.Start, but every time I try to open a file that isn't an executable the program crashes... This is the code I'm currently using:
vb.net Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick For Each lvi As ListViewItem In ListView1.SelectedItems Process.Start(path & "" & lvi.Text) Next End Sub
Path is a string that contains the selected folder path, and lvi is the text of the list view item (each item contains the icon and name of each file). It is working fine for .exe files, I was just wondering if it's JUST for .exe files...
Dim myProcess As New Process() Try myProcess.StartInfo.UseShellExecute = False myProcess.StartInfo.FileName = "C:windowssystem32wuauclt.exe" myProcess.Start()
I am facing a problem which I believe is due to the garbage collection within .NET. I have the following conundrum where I am getting files from a folder, adding them to and array and then converting them all into one file. Once this is done I move this new file elsewhere, and need to delete the previous files.
I encountered the error:The process cannot access the file <full file path> because it is being used by another process.during System.IO.File.Delete(filename)I have opened the file using:pctPhoto.Image = Image.FromFile(filename)before I delete the file.
I am using a System.Diagnostics.Process to execute dirquota.exe. I catch an exception at .Start() which is "The system cannot find the file specified".
I am now doing:
foreach (var fi in new DirectoryInfo(@"C:WindowsSystem32").GetFiles()) { Console.WriteLine(fi.Name); }
This outputs pretty much every file in that directory apart from dirquota.exe.
My first post! im quite new to programming but loving every minute of it.Basically i want to open another exe file from vb.net 2010. i can do it normally using
system.Diagnostics.Process.Start _ ("c:winamp.exe") if winamp for example is installed on another pc in another location i want to run it from my program but i want there to be sort of like a settings.txt file where you can edit the path to winamp and my program should first read the path set in the settings file and then open accordingly. how do i go about doing this?
btw it would be great if you could point me in the right direction for making a windows form where one can edit the settings file within my program without editing the settings file in notepad
how to check a file which i want to delete is not more used by another process?I have a program it creates a temp file less than 1KBthen it sends it like an attachment in the emailthen I have to delete it,but cannot do it because exception comes out that it still used by another process
Try Dim AnEmailMessage As New MailMessage AnEmailMessage.From = New MailAddress("bla@bla.com")
Im simply trying to load a file on my network. The file is a database file for access.. This code opens the file on my computer. However on the four computers tested 2 of them throw an error stating that the user canceled the operation. However the user didn't do anything. The error is thrown automatically. The other two are working perfectly fine.
I am trying to create an MDB as a temp file to save some tables and query them. After creating, I can't delete it ... Even before it is actually used. The process cannot access the file because it is being used by another process.
Dim mdbFileName As String = System.IO.Path.GetTempFileName Dim objClassType As Type = Type.GetTypeFromProgID("ADOX.Catalog") Dim obj As Object = Activator.CreateInstance(objClassType) obj.[GetType]().InvokeMember("Create", System.Reflection.BindingFlags.InvokeMethod, Nothing, obj, New Object() {"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & mdbFileName & ";"}) [Code] ..... This MDB (after all operations) is huge (+200 Mb) and needs to be deleted.
I'm having different results when running openfiles.exe manually than when I run it with Process.start() Below is the portion of code making the call. I have read in several places that using the "runas" verb might make a difference since I am running on Win 7 x64, however I am still experiencing different results.
i wanted to know how i can end a process if it runs more then like 10seconds. I am coding a tool that runs a Perl Script but if the Perl Script doesent work then it just hangs at 1 point so it doesent go further what i wanted to do is tell the Program to end the Process after 10 Seconds.
Dim proc As New Process For Each names As String In lb_1.Items With proc.StartInfo
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.
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.
I'm in need of a timer that runs a process every 31.25 milliseconds. Thus, after 768 "ticks" have gone exactly 24 seconds.The control "Timer" that exists in Visual Studio does not accept decimal values.So I had to round the value of the range to 31 or 32. But this raises a problem since the end of the 768 ticks there is a difference of half a second or more. And I need to run the 768 ticks in exactly 24 seconds.I've been researching, and I read some things about the "High-Resolution Timer. " But I did not understand exactly how to use it, and how to set your interval to 31.25 mils, and do that every period of this interval to run the code.
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.
Trying to create a button that when clicked will check to see if a certain process image is running and if that process is running give the process focus. If the process is not running then start the application.
I develop an appliaction which is running a process in the background. This process is "forked" from the application (I'm not using threads). The process may take a few minutes while the 'father' application is waiting to the process output, so I'd like to enhance the application with the following:
a) a "Stop" button (like in IE, FireFox) to stop the process in background
b) A status bar that displays what's going on while the process is running in BG.
how to draw a button or status bar of course... I mean how VB.NET handle with stopping or displaying while something else is running in background and how to do it.
