Hi i am using kernel32.dll for creating the files (pdf file)

Hi, i am using kernel32.dll for creating the files in my remote server.

i am using default function for creating the files as folllows

[DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]

static extern SafeFileHandle CreateFile(string lpFileName, uint dwDesiredAccess, uint dwShareMode, IntPtr lpSecurityAttributes, uint dwCreationDisposition, uint dwFlagsAndAttributes, IntPtr hTemplateFile);

Calling the above method by referring safefilehandle class like this,

this.Handle = CreateFile(filePath, GENERIC_ALL, FILE_SHARE_READ, IntPtr.Zero, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, IntPtr.Zero);

i was able to create a new file but what i observed is that .exe which i was generating a file was not releasing the file and it is saying that it is in open mode. i was unable to access that file for further modification.

If i restart my .exe at that time it was releasing the file and i was able to do the things. Only when i was creating a new file it was not releasing.

I am making the handle to close the file. Even then also i was unable to do.

This is happening only when i was creating a new pdf file in the remote server.

Since i was struck with this, i need a solution very fast.

Thanks in advance.

Hi Mukesh,

Thanks for reply, I was releasing that object after writing into filestream. When i check the safeFilehandle object after writing into pdf file it was in close state. I made all types of dispose(). Its not working. Will be there any permissions of configurations need to set for this UNC Filesystem.

thanks.

Hi,

I think you should release the object which is holding the file.

thanks
