Post subject: | Cannot access the file because being used by another process |
When the PDF file has been created and is still open in Adobe Reader an exception error occurs. Here is the stack Trace: Quote: System.IO.IOException HResult=0x80070020 Message=The process cannot access the file 'D:\Visual Basic Projects\My Greeting\My Greeting\bin\Debug\Verse.pdf' because it is being used by another process. Source=mscorlib StackTrace: at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access) at PdfSharp.Pdf.PdfDocument.Save(String path) at My_Greeting.frmPrintFrm.printIt(DataRow row) in D:\Visual Basic Projects\My Greeting\My Greeting\frmPrintFrm.vb:line 156 at My_Greeting.frmPrintFrm.btnPrint_Click(Object sender, EventArgs e) in D:\Visual Basic Projects\My Greeting\My Greeting\frmPrintFrm.vb:line 97 at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(IntPtr dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.OnRun() at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.DoApplicationModel() at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(String[] commandLine) at My_Greeting.My.MyApplication.Main(String[] Args) in :line 81 Karen @ MDSN suggested adding line: document = Nothing But this did not solve it. Had an idea of creating a For Next loop to add a number to the filename, but iterated all the range before leaving the form. Can you advise a method to cure this problem? |

I fixed it very simply by creating a random number between 1 and 100000 and concatinating this into the filename. Problem solved! |
