.NET Forum / .NET Framework / New Users / June 2007ASP.Net problem with process.start
Hi, I've build a custom web service that is used to digitally signed cab files that are used to install smart devices application. Using a standard Process.start and processstartinfo pattern, I run this command line : filename : c:\Program Files (x86)\Microsoft Visual Studio 8\Common7\Tools\Bin\signtool.exe command line arguments : sign /f "c:\test\mykey.pfx" -p "password" /v "c:\temp\cabfiletosign.cab" When this process is executed, and even if the files actually exist (I've check many times), I get the following error (from the standarderror stream of the process object) : -------------------------------------------------- Number of files successfully Signed: 0 Number of warnings: 0 Number of errors: 1 SignTool Error: File not found: c:\test\mykey.pfx -------------------------------------------------- If I run exactly the same code (a class lib that is referenced in the WS) from a windows desktop application, I get the following behavior : -------------------------------------------------- The following certificate was selected: Issued to: Our company Issued by: the company Expires: 01/01/2009 01:59:59 SHA1 hash: the hash Done Adding Additional Store Attempting to sign: c:\temp\cabfiletosign.cab Successfully signed: c:\temp\cabfiletosign.cab Number of files successfully Signed: 1 Number of warnings: 0 Number of errors: 0 -------------------------------------------------- I've set up IIS 6 to make the web service run with a specific user with it's own app pool. I've also check that the web service's user can access to all files that are needed.. Does anybody have an idea about this difference ? Is there any env variable that could cause ASP.Net web apps to work differently ? Thanks in advance, Steve Hello, Steve! ASP.NET and common destop app can have different working directories. Try to set UserShellExcute to false and see what will happen.

Blog: http://vadmyst.blogspot.com Since I'm using full path and not relative path, I don't think this could be a working directory problem. Here is the process.start wrapper I wrote to launch the signtool.exe process --------------------------------------------------------------------------- public static string StartProcessAndGetOutput( string fileName, bool runInFileNameDirectory, string arguments ) { string log; ProcessStartInfo psi = new ProcessStartInfo(); psi.FileName = fileName; psi.Arguments = arguments; if (runInFileNameDirectory) psi.WorkingDirectory = Path.GetDirectoryName(fileName); psi.UseShellExecute = false; psi.RedirectStandardOutput = true; psi.RedirectStandardError = true; StringBuilder sbLog = new StringBuilder(); using (Process p = Process.Start(psi)) { string output = string.Empty; while ((output = p.StandardOutput.ReadLine()) != null) { sbLog.AppendLine(output); } sbLog.Append(p.StandardOutput.ReadToEnd()); sbLog.Append(p.StandardError.ReadToEnd()); p.WaitForExit(); } log = sbLog.ToString(); return log; } --------------------------------------------------------------------------- As you can see, I disable UseShellExecute, and I also added a parameter that allow me to specify if the working directory is the filename directory. You can also notice that the error message returns the full path of the targeted file... which is correct.

I'm sure that you've already checked that but are you sure that the file you are trying to sign is really placed on the machine on which the Web Service runs (the web server) and not on the machine on which you are accessing it the web service. The web service is running in the developpement computer... thx >> As you can see, I disable UseShellExecute, and I also added a parameter >> that [quoted text clipped - 7 lines] > Service runs (the web server) and not on the machine on which you are > accessing it the web service. Hello Steve, the program may need access to a temporary files folder. I'd suggest you get FileMon from Microsoft (formerly Sysinternals) and check for Access denied messages. Best regards, Henning Krause > Hi, > [quoted text clipped - 54 lines] > Thanks in advance, > Steve Thanks all for your feedbacks but I finnally "unblocked" the situation... I reset the password of the user that runs the app pool (to the same password !!!, app pools worked and continued to work), and at this point, the web service started to work properly. I can't find any explanation of this "magic" behaviour... but it's working now. Thanks for all people that tried to help me !
