Hi All,
am using [DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)] to access, save files to a network location. The problem is File creation / save work fails for first few attempts and laters starts working fine. After a time interval say 5-6 hours again it fails first few time. Kindly help
Thanks in advance

OK, but unless you show a bit of your code and the exact error details, we cannot begin to guess what may be happening.
Use the best guess

Hi this is the error i get when saving file on the network location
FileStream was asked to open a device that was not a file. For support for devices like 'com1:' or 'lpt1:', call CreateFile, then use the FileStream constructors that take an OS handle as an IntPtr.

That seems quite clear; so what is your problem?

It's that invisible code that you are using that's causing the problem.

Am using Docx.dll its a open source dll from code plex

I don't know how much clearer I can make this, but show us your actual code. Giving us a part of a command here or a definition there doesn't cut it. You are just wasting your time and ours until you actually show us your code. It doesn't need to be all your code - just show us the code that isn't working.

Here is a part of code
string FAXFilePrefix = Helper.Helper.GetConfigValue("FAXFilePrefix");
string domainName = System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
string location = GetLocalStoragePath() + FAXFilePrefix + requestViewModel.encounter.ServiceEncounterID + "_" + uniqueId.ToString() + ".docx";
MvcApplication.TraceSource.TraceEvent(TraceEventType.Information, 100, "Before Accessing UNC path ");
using (Carena.PCHA.CoreServices.UncPath.UNCAccessWithCredentials unc = new Carena.PCHA.CoreServices.UncPath.UNCAccessWithCredentials())
{
if (unc.NetUseWithCredentials(Path, userName, domainName, Password))
{
MvcApplication.TraceSource.TraceEvent(TraceEventType.Information, 100, "Before docx.SaveAs ");
MvcApplication.TraceSource.TraceEvent(TraceEventType.Information, 100, "Location - "+location);
try
{
docx.SaveAs(location);
}
catch (Exception ex)
{
loggerl.LogException(ex);
}
MvcApplication.TraceSource.TraceEvent(TraceEventType.Information, 100, "After docx.SaveAs ");
}
It throws exception at docx.SaveAs(location); line

I don't see anything in there to do with this DllImport code though. Is this what's happening inside this docx component? If so, I suggest that you should raise it on the support forum for that component.

Given that you have provided even less information than posted here, I would be surprised if you see anything. Why not use your debugger to diagnose the exact situation at the point of failure and then provide all the information that you have, so someone can try and help you?
Use the best guess

OK, so what's the EXACT contents of location when it fails??
|
|
|
|
|
\\remote comp ip\foldername\filename.docx which is correct
|
|
|
|
|
That's not the EXACT contents. That's just the format you expect it to be in when this code runs.
|
|
|
|
|
Its true that what i have shown is format. But i can't show the actual path. The path i get is as expected
|
|
|
|
|
Oh well, I guess you're on your own now, because the problem seems to be with that path.
