Struggling to Connect
#31
Deak, out of curiosity, did you set your debug build to 64-bit? If so, that might not work. There are a few things out there that point to a bug in .NET with regard to 64-bit debugging that produce the same error. You may have to build for X86 instead of All or X64. It may even be possible that things won't run on 64-bit.

These guys have the same problem.

Yes you are right this is when I try to connect the device. The debug information is the one i sent you.. PFA the screenshot..

I saw that bug robo, but I also have a Windows 7 64 bit machine and it runs fine on mine so I have ruled that out. I am not familiar enough with the coding language to know what the cause it, but looks like some hardware during the scan is throwing an error. What happens if you unplug the Ultra and try to connect? If it throws that same error, there is some hardware that is causing the error I think.

I'm able to connect via the leapfrog usb cable but not the PL2303 Cable. So what i'm asking is which one of these cables do i need to be able to use the download file & send command features on the leappad manager. I'm on windows 7

I am not sure if the send command and download features are available in the public release of the software and is not fully implemented. The easiest way to transfer files is via FTP. The leapfrog manager app only works with a USB connection to the USB slot on the device. Hooking up a PL2303 cable is only for direct shell access.

Was this resolved? I feel like talks just disappeared. I am having the same issue (Leappad Ultra, Win7-64, Run as Admin, disable UAC, etc.) but my error is slightly different:
Code:
\\.\PhysicalDrive0 - ID: WDC WD3
\\.\PhysicalDrive1
ERROR: System.NullReferenceException: Object reference not set to an instance of an object.

I wonder what is on your PhysicalDrive1. Have you limited any connections to your PC such as thumb drives, external drives etc?

I wish that I knew the cause of these, but am not that knowledgeable with c# and only know most of the basics. Perhaps it is the way it is scanning devices or something. I do believe that it is due to conflicting with some type of hardawre which throws the error and stops the scanning because as you can see it found the first device fine, then fails on the second one.

Sonuva ... there was a stupid memory card in my computer. Ejected and it connected. Sorry for being dumb. (Thank you for your assistance.)

I'm back again, and confused as always ...
I had this running for five months adding videos left and right - no problem. Updating the Leappad with games, then re-installing - no problem. And then, I tried the same thing today: downloaded/synced games through Leapfrog Connect, went to connect and wah-wah-wah ... nothing:
Quote:\\.\PhysicalDrive0

ERROR: System.IO.FileLoadException: The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)
   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)

   at Helper.IO.Win32FileStream..ctor(String path, FileAccess access, FileShare share, FileMode mode, FileOptions options)
   at LFConnect.dftp.findDevice()


Monitor is not running, no LF items running - hell I even uninstalled it for a minute. Nothing.
Perhaps it has always been there, but under Device Manager - Disk Drives: there is LeapFrog LeapPad Ultra USB Device. I have disabled this, that didn't help either. I dont' know if Leapfrog updated something that is locking me out or what it is, but I have the latest version of Manager 7.3.3, and can't seem to get past the error posted above. (I don't have anything else plugged in this time ... I am guessing from the error message that the LF Manager is not getting past the hard drive in scanning?)
Thank you in advance for dealing with my ignorance.

Strange, yea seems like something is accessing PhysicalDrive0 which makes the app scanner fail. I wonder if I can adjust the script to continue trying other drives if one fails to scan. I have not touched my code in quite a while. I am also curious if it is the tablet that is failing to scan or something else on the computer.

I may have to connect a tablet online to get the latest update and then try it again. If it somehow got put into develop mode, that would cause the app to not be able to connect to it.

Problem is trying to find some time to take a look at it.
