anyone know educational visual basic source code for HPC-2000?

i'm trying to play with embedded visual basic 3.0 maybe i can solve my 'external buttons for audibleplayer' problem in this thread: http://www.hpcfactor.com/forums/forums/thread-view.asp?tid=981&posts=7


so i need some VB educational source code for hpc2000...

thanks,

msafi,

i found the sample code that Snappy! referred to. it comes with the SDK like he said.

but man, if you don't know c++, using the API makes eVB just as hard as C++. it sucks. to execute a file in a desktop Windows VB application all you do is use the method Shell ... with Windows CE API's, it's a different story. use something like ShellExecuteEx, and get the pointers and dlls and many other things...

i think i'll just give up... if it's that hard to do a simple thing such as executing a file, how would i do the taps, and accessing the external buttons and all of that...

msafi, I know your pain.

We need to form a Timid Coders (TC) meeting, it's like an AA meeting but instead we stand up and say "My names <name> and I'm a code newbie"

Then Snappy! as a reformed Code Newbie; and group lead. Can help us through our problems

Snappy!

i really appreciate you offering to help me. i hope you can wait for me while i find sometime to work on the code because we are approaching the finals season and everything is starting to pile up so quickly.

getting started with something like coding is really tough. it took me almost 4 hours just to figure out what command i need to use to do 'open program'... can you believe it?

that's why i need time...but once i have my grip on it, i can take off...i did experience that feeling once before actually!! (extensive mIRC scripting 6 years ago)

thanks,

msafi,

Step-by-step using of the VBPointers library
The following instructions will help you to call a Windows API function from eMbedded Visual Basic.

* Copy the VBPointers.dll to the \windows directory of your device.
* Include the VBPointers library declaration into your eVB code. You can find the necessary eVB declarations in the library package.
* Write a declaration for Windows API function. Pointers to structures should be replaced by Long.
* Calculate the size of the structure in bytes. There is a simple eVC program in the package that can calculate sizes of structures.
* Pass the calculated size to the AllocPointer function. It will allocate a memory block and initialize it with zeros.
* Calculate the offsets of the structure's members. You can use sample eVC program to calculate offsets.
* Use SetLongAt, SetWordAt, SetByteAt with calculated offsets to set necessary fields of the structure. Use AllocStringPointer to set string (e. g. LPTSTR) members.
* Call the Windows API function. Use the memory block handle as a pointer to the structure.
* Read the necessary structure's fields using GetLongAt, GetWordAt, GetByteAt with calculated offsets. Use CreateString to read string members (e. g. LPCTSTR).
* Free the memory block using FreePointer.

The simplest way to calculate offsets and a structure's size is to use the simple eVC program from the library package. If you don't know how to compile and run eVC programs you can request the information about certain structure's parameters from eVC developers. For example, you can post the request to the DEVBUZZ eVC forum. In this case the answer will be available for other eVB developers.

Using ShellExecuteEx

Private Sub ExecuteWord()
Dim ExecuteInfo As Long
' pointer to SHELLEXECUTEINFO structure
ExecuteInfo = AllocPointer(60)
Call SetLongAt(ExecuteInfo, 0, 60)
' size of the structure
Call SetLongAt(ExecuteInfo, 16, AllocStringPointer("pword.exe")) ' file name ShellExecuteEx (ExecuteInfo)
FreePointer (ExecuteInfo)
End Sub
