VB p2k source code

[swampsucka247]

Is anyone here into p2kapi programming with VisualBasic.NET? I can't seem to find many examples to learn from. Know of any good places to start or have a link to share?

[MstrSteve]

I know a lil something about visual basic. What exactly are you asking about? If it's api code specific, I'll need to know 3 things:

1) What version of Visual Studio you are using as many things are different between 2003 and 2005.

2) What you are trying to do. (just the general idea)

3) Where you got the P2kapi so I can Download it to see how it was coded. ie: variable names, array lists, parameters, database type(if any),etc.

1) I have Visual Basic 2005 Express

2) I'm really not trying to reinvent the wheel or anything, I just have a love of this sort of thing.. I really would like to have a better understanding of how the p2kapi.dll is used to communicate with, and manipulate the device. I realize that there is a program out there that can do anything that I need to do to my phones, but being able to see the code, that I wrote, running, just gets me all excited because I am a nerd :cool: I have some experience programming smart cards,and a *little* PLC programming and that sort of thing - kind of a hobby, I guess you could say.

3) If you want, I will PM you a link to my *massive* :lol:(it's like 60kb, zipped) stash of code and maybe you can find something useful in there! Or I guess I can post it for all, if anyone else is interested.
This includes code by Vilko, dwALX, s5vi, & motoprogger.

Thanx. I'll have a look at it and see what is what. Give me a day or 2 to get my bearings in the code and do a few tests.

[swampsucka247]

so far all i've been brave enough to do to my phone was to reboot it and get the status didn't want to get into the seem functions just yet... all i've got is this one v3i right now... hindsight - see post here -> doh! (http://motomodding.us/viewtopic.php?t=678&highlight=) :bang: intrested to see what you find

[swampsucka247]

just a thought

I guess it ain't all Hee-Haw and Larry the Cable Guy out here in the sticks anymore, but i haven't found anyone else in the State of Arkansas who would be into using .NET to mod thier cell phone - lol

[MstrSteve]

How did you go about figuring what parameters to send to the p2kapi2.dll or what functions to call? I had to get an external decompiler to get into the .dll source code. I'm finding the .txt files rather unhelpful as they seem rather thrown together rather than laid out in a way that encapsulates individual processes. I understand your confusion entirely. lol

Free Decompiler found here (http://www.aisto.com/roeder/dotnet).

Add-ins for Decompiler here (http://www.codeplex.com/reflectoraddins).

lol good so it's not just me, then! I'm gonna check out that decompiler tonight - thanks for the link!

Re: Reboot was done with a bas that I had, and cannot find at this moment - will try to locate 4 you - peace

Log(clBlack,"p2kapi.GetFileListEx: completed %2.0f%% - %s",f,fl[CurIndex].FileName);
}
...
// somewhere, when we want to get filelist
int FileCount = p2k->GetFileCountEx("/a/*");
FILELIST *fl = new FILELIST[FileCount];
p2k->GetFileListEx(FileList,FileCount,TestFunc);



Mode_SwitchToP2k(StatusProc)
Switch phone from AT mode to P2K
if not called P2K_Init, it's will be called with StatusProc parameter
(no return value)

Mode_SwitchToAT()
Switch phone from P2K mode to AT
(no return value)


P2K_Init(StatusProc);
Library initialization, phone status monitor starting.
StatusProc - pointer to a procedure, that will be called on phone detect/disconect (or 0, if procedure call is not needing).
Returns 0 on initialization success or 1 on failure.

Library calls StatusProc procedure with one parameter:
1 - if phone detected; 0 - if phone not detected.


P2K_Restart();
Restart a phone.

P2K_Suspend();

File_CreateDir(lpstr FileName, byte Attribute);
Creates new directory

lpstr DirName - pointer to string containing a directory name
byte Attribute - new attribute for a created dir
Attribute is combination of 3 bits:
bit0 - readonly
bit1 - hidden
bit2 - system
Returns always 0.

File_DeleteDir(lpstr DirName);
Deleting a directory

lpstr FileName - pointer to a string containing directory name

Returns 0 if success or -1 on error.


File_Create(lpstr FileName, byte Attribute);
Creates new or opens existing file

lpstr FileName - pointer to string containing a file name (in case of nested filesystem - full path with directories)

Attribute is combination of 3 bits:
bit0 - readonly
bit1 - hidden
bit2 - system

Phone not allows to open more than 1 file simultaneously.
Returns 0 if opening was success or -1 on error.
(advanced error codes - :) please wait for next version)

File_Close();

Returns 0 if closing was success or -1 on error.

File_Read(ptr Buffer, dword Size);
Reading data from file.
Reads data from BOF or from position, what was setted by File_SetPointer function.

ptr Buffer - pointer to a buffer for receiving data from a file.
dword Size - data size to read. Buffer size couldn't be less then this size.

Returns 0 if reading was success or -1 on error.

File_Write(ptr Buffer, dword Size);
Writing data to a file.
Writes data from BOF or from position, what was setted by File_SetPointer function.

ptr Buffer - pointer to a buffer containing data to write.
dword Size - data size to write.

Returns 0 if writing was success or -1 on error.

ATTENTION! This function not checks a free space for writing.
But phone needs for a some free space for temporary files created by phone.

File_SetPointer(dword Offset, byte MoveMethod);
Set pointer to file reading/writing

dword Offset - new position of pointer

ptr Buffer - pointer to a buffer for files list receiving
files list is saved as:
dd file size
dw attribute 1
dw attribute 2
string of 1F8h length - file name.
Record size per 1 file is 200h bytes
Records count is equivalent to files count in phone (result of File_Count() function)
According to this, size of buffer for files list must be File_Count*200h

word Count - files count to read (result of File_Count() function)

Returns a maximum length of file name for current phone model or -1 on error..


Seem_Read(word SeemNo, word RecordNo,word StartOffset,word Bytes, ptr Data);

If those are the variable designations for functions, then yes it looks about right.

I'm not really sure what you're asking me. If your asking if they will work the way you want them to.... lol you know what I mean.

Remember you have to instanciate(sp?) them up top b4 the page load event but under the auto generated code section in VB.

[swampsucka247]

If those are the variable designations for functions, then yes it looks about right. 8) - yeah that's what i was asking about! - thought i'd ask you about it thought maybe i had missed something in the desiginations - thanks again MstrSteve - :wink:

[vermsky]

Just a suggestion, but you may want to check the How to create FB3 profiles in the guides section for additional info about the structure of the flashfile. I do think that it's helpful.

[swampsucka247]

Thanks vermsky i will check it out!

btw a woodchuck would chuck as much wood as a woodchuck could chuck, if a woodchuck could chuck wood.
