Gecko dotNET release thread (version 0.65 now!)

Hi Link,

I looked through the source code and I don't see anything that appears to pin the byte[]'s you're using in GeckoRead and GeckoWrite, so I modified them to pin their byte[]'s down in case the Garbage Collector decides to move the buffers while the driver is using them.

       protected FTDICommand GeckoRead(Byte[] recbyte, UInt32 nobytes)
       {
           UInt32 bytes_read = 0;

           GCHandle bufferPin = GCHandle.Alloc(recbyte, GCHandleType.Pinned);
           FT_STATUS ftStatus = PFTDI.Read(recbyte, nobytes, ref bytes_read);
           bufferPin.Free();

           // etc
       }

       protected FTDICommand GeckoWrite(Byte[] sendbyte, Int32 nobytes)
       {
           UInt32 bytes_written = 0;

           GCHandle bufferPin = GCHandle.Alloc(sendbyte, GCHandleType.Pinned);
           FT_STATUS ftStatus = PFTDI.Write(sendbyte, nobytes, ref bytes_written);
           bufferPin.Free();

           // etc
       }

If I were to continue with any more changes, what is the appropriate way to submit them to you?

Thx, it's okay, just to post the code, I included it.. for the SafeHandle thing.. I wasn't really able to figure that out as all of MS examples always expected to use Safehandle at function which would have a DWORD as output (DWORD File_open(params) ) and not where the DWORD is the result of a pointer ( DWORD Open_Ex(params, DWORD* handle) - other than that.. let's just hope that kinda fixes the known issues..

thanks though!

Yeah, the SafeHandle stuff is a bit confusing.  But the good news is that unless the DWORD is being boxed, it's a value-type and not a reference-type, so it won't need to be pinned.  I hope.

I am also having freeze when using unknown search, the initial search is fine
but the refine search sometimes freeze the game

Version 0.41:

Changes:
-refining should be fixed (spotted the error)
-readme now included
-breakpoint fixes
-dec to hex buttons removed, context menu instead which also provides float to hex and such
-search within memory view added (non-functional yet, it's being prepared right now, the button won't do anything).
-under-the-hood-changes

Sources haven't been updated!

Thanks :D your effort is much appreciated.

Yeah, nice one Link

[dcx2]

Hooray thank you!

Hi Link,

Whenever I try saving codes in GeckoDotNet I get an error. While I do not have my laptop with me, it gives me a giant paragraph and I believe the keywords (again I do not have my laptop to verify this) code handle exception error.

I am running Windows 7, 64 bit, home premium.

Thanks in advance,
Z

Does this only happen on WiiWare/VC?

[hetoan2]

Thanks for the update Link. Can't wait for the search in memviewer. Hopefully it's faster than WiiRD's :P

Hopefully in the future we can look forward to undo/redo search options and a function to export all the data you have in GeckoDotNET to a notepad.txt would be good too :D

Does this only happen on WiiWare/VC?

Good eye, it is only happening in VC/WiiWare. I remember that WiiWare and VC games have different organization of Title IDs not isomorphic to the structure of Wii games. That answers everything ;)

[Romaap]

I just noticed that when you load WiiWare/VC the game id is shown but it is like this: (GAME
It is missing the )
So the game id might not be stored correctly thus causing an error when trying to save to a file with that broken name.

[Panda On Smack]

It's basically to do with the length of the game id

I just edited the source and changed it to loop through 4 characters instead of 6 and it works fine on a VC game

It errors on the 5th character as it doesn't exist

Saweet!  Memory Viewer updates the FP value displayed when auto-updating!  And you can click away from the memory viewer tab, that rocks too!

I added some requests.  When you update the sources, I'll see if I can handle any of them.

EDIT:

Uh-oh!  I got an ftdiusbgecko.eusbgeckoexception while I was trying to set/cancel a breakpoint.

Normally when I get an exception in a .NET app it shows something about the stack trace, but there was no trace, so that's all I have... =(

EDIT2: Got another one. =(  Stack trace this time, woohoo!  USBGecko.peek() gave up the ghost
