问题
On my PC DWG files open with:
"C:\Program Files\AutoCAD LT 2007\acadlt.exe" "%1"
If I run this from the command line:
"C:\Program Files\AutoCAD LT 2007\acadlt.exe" "C:\Some Path\Test.dwg"
AutoCAD Lite open the DWG file.
Similarly if I open a command prompt and run the same exe with argument, it works fine.
However if I use
var proc = new System.Diagnostics.Process();
var info = new System.Diagnostics.ProcessStartInfo();
and then
info.FileName = "C:\Some Path\Test.dwg";
proc.StartInfo = info;
proc.Start();
or
info.FileName = "C:\Program Files\AutoCAD LT 2007\acadlt.exe";
info.Arguments= "C:\Some Path\Test.dwg"
proc.StartInfo = info;
proc.Start();
or
info.FileName = "cmd.exe";
info.Arguments= "C:\Program Files\AutoCAD LT 2007\acadlt.exe" "C:\Some Path\Test.dwg"
proc.StartInfo = info;
proc.Start();
I get the following error:
acadlt.exe - Application Error
The instruction at "0x01317c8c" referenced memory at "0x01317c8c". The memory could not be "read".
Click on OK to terminate the program Click on CANCEL to debug the program
OK Cancel
Incidentally the code works ok if I step through the code with the debugger.
Anyone know how I can use Process.Start to open this DWG?
回答1:
Make sure to have the correct working folder specified:
info.WorkingDirectory = "same path as current directory in cmd.exe";

One difference between launching from the command line and using ProcessStartInfo in this manner is that the latter uses shell execution. I don't think it's likely to be causing this problem but can cause issues. Try adding the following and seeing if it fixes the problem.
info.UseShellExecute = false;

It turns out that it was Xenocode Postbuild causing the Application Error. If I run the same code on a normal .NET exe (not obfuscated), it works fine. I have referred to Xenocode for a solution.
