Solution 1

In .net 3.5

C#

using (Process proc = new Process())
               {
                   proc.StartInfo.UseShellExecute = false;
                   proc.StartInfo.CreateNoWindow = true;
                   proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                   proc.StartInfo.FileName = "ABC.EXE";
                   proc.StartInfo.Arguments = "Report 06202012 42554 PM.pdf";
                   proc.StartInfo.RedirectStandardError = false;
                   proc.StartInfo.RedirectStandardOutput = false;
                   proc.StartInfo.UseShellExecute = false;
                   proc.StartInfo.CreateNoWindow = true;
                   proc.Start();
                   proc.WaitForExit();
               }

proc.WaitForExit(); This is the key

In CMD:

XML

Use the "Start /wait <command>". <command> = D:\ABC Report 06202012 42554 PM.pdf

Can you elaborate a little please?

As I understand you are using C#. The code above is executing the abc.exe tool with "Report 06202012 42554 PM.pdf" as argument from your example "ABC Report 06202012 42554 PM.pdf". The proc.WaitForExit() is used to make the current thread wait until the associated process terminates.[^]
Right after the "using" block the ABC process is finished and the PDF document should be released(if it is not locked by some other process), it's mean that you can delete, move or change it.

If you want to delete the pm.pdf document your code should look like this:
using (Process proc = new Process())
{
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.StartInfo.FileName = "ABC.EXE";
proc.StartInfo.Arguments = "Report 06202012 42554 PM.pdf;
proc.StartInfo.RedirectStandardError = false;
proc.StartInfo.RedirectStandardOutput = false;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
proc.WaitForExit();
}
File.Delete("PM.pdf");

sorry for my English

Can we see a code that is responsible for sending a PDF file via e-mail? Your problem might be caused by not released memory stream. If you're using an Attachment class then you should do like the following:

C#

using (Attachment data = new Attachment("document.pdf",  MediaTypeNames.Application.Octet))
{
    // 1. Adding attachment to the e-mail message
    // 2. Sending out the e-mail message
}

After calling the Send method make a call to Dispose of your mail message object:

C#

objSMTPClient.Send(objMailMsg); 
objMailMsg.Dispose();
