Network Directory Not accessible through .NET Assembly

2012-04-12 16:44

Hi,
I am using this new .NET dll and was having problems when I use this in my application from a network drive location which is a shared location. All the time the WinSCP.dll seems to truncate the root element. Say for example, if I am using the following path '\\NetworkRoot\dev\myproject\' where my project code resides, the WinSCP dll throws an exception that it can't find the WinSCP.dll in the following path '/dev/myproject'. Notice that this message somehow truncates the root folder name. I suppose this may be because your code doesn't properly amke use of the System.Reflection classes to get the path to the executing assembly when the project is run from some network location. Have you released the source code for this dll, so that I can take a look?

Please resolve this issue. I appreciate your help.

Thanks for your post.
Assembly source code is not released yet.
The code for determining assembly path is:

string codeBase = Assembly.GetExecutingAssembly().CodeBase;
UriBuilder uri = new UriBuilder(new Uri(codeBase));
string codeBasePath Uri.UnescapeDataString(uri.Path);
string path = Path.GetDirectoryName(codeBasePath);

What do you suggest?

Code Fix - .NET dll

2012-04-22 16:03

Hi Martin,

Given below is a tested code fix which I believe returns me the complete path of the network directory where the dll is located. See my comments below: Let me know if this works.
string codeBase = Assembly.GetExecutingAssembly().CodeBase;
//UriBuilder uri = new UriBuilder(new Uri(codeBase)); //instead of using this line
Uri local = new Uri(codeBase); //use this
//string codeBasePath = Uri.UnescapeDataString(uri.Path);
string codeBasePath = Uri.UnescapeDataString(local.LocalPath); //this local.LocalPath returns me complete Uri instead of truncated host
string path = Path.GetDirectoryName(codeBasePath); //this gives me full path
Thanks,
James

I tested it out. Now the program hangs once it executes session.Open(sessionOptions). It doesn't respond at all. I can't tell what exactly the problem here is when it tries to access the WinSCP dll in my project folder which is located in the network drive. Now it doesn't truncate the root of the network folder but it just hangs.

Please set Session.DebugLogPath and post or email the log file.

I also tried to set the session.ExecutablePath but still it hangs.

My guess is that winscp.exe you are starting from network folder is not 5.0.6 beta. Did you override the version check with Session.DisableVersionCheck? Note that the winscp.dll works with winscp.exe 5.0.6 beta only.

Yes, I tired both ways. First I tried using the exe that you sent alongwith the WinSCP dll which resulted in an exception because of version of WinSCP. So then I used Session.DisableVersionCheck and after the session.Open(sessionOptions) it simply hangs. I tried using the 5.0.6 beta alongwith the dll you sent but still the same result.

Please advise. Maybe if you could try using it at your end from a netwrok drive location for your project then you could be able to find the issue.

I've sent you new build. Please repeat the test with it, without DisableVersionCheck. Post a debug log file.

I've tried it myself. But it works for me.

I am having this problem, any timeline for this to make it into the beta?

I can specify the executable path, but then it fails to find the DLL.
"/some/long/unc/path/name/in/this/format/WinSCP.dll"

The path I specified was
"\\some\long\unc\path\name\in\this\format\WinSCP.exe"

Failed due to version check. I disabled the version check and it sent.
