API/SDK With C# -> OpenFile ?

Hi,

I'm trying to use the BSPlayer API with C#, I can get everything working.. but i'm stuck on the OpenFile method.

I can't get the cds.lpData part right with the address of the filename.

Does anybody allready know the anwser? I tried searching, and found the same problem... but no answer.

Thanx,

Grim

Since I don't think you mean to create a plugin for BSplayer v0.8x but instead you want to create a plugin for v1.00+ you can try to use this simpler command:
SendMessage(bsp_hand,WM_BSP_CMD,BSP_OpenFile,"File Name");

Didn't do the trick

Hi thanks for replying,

Don't know why I didn't try it like that, but when I use the given command BSPlayer crashes. Doesn't bsplayer expect a COPYDATASTRUCT as the object instead of the Filename string?

Hi, I tried to use that command with VisualBasic and I had an error message too :?
Probably I really lack of programming knowledge if I'm not able to make it work that way if I don't use C++...

This is the WORKING routine that I use with VB, I hope you'll find it useful (lines starting with ' are comments):

Code:

Public Sub BSPOpenFile(FileName As String)

    Dim cds As COPYDATASTRUCT

    

    'Find BSplayer window's handle

    bsp_hand = FindWindow("BSPlayer", 0&)

    'If BSplayer is running -> window found

    If bsp_hand <> 0 Then

            

        'Set OpenFile as action

        cds.dwData = BSP_OpenFile

        'Create and set the pointer to the file name string

        '(VB doesn't provide pointers like C does)

        cds.lpData = lstrcpy(FileName, FileName)

        'Set the string lenght

        cds.cbData = Len(FileName) + 1

        

        'Open the selected file

        ReturnCode = SendMessage(bsp_hand, WM_COPYDATA, 0&, cds)

        

    End If

End Sub

EDIT:
Almost forgot, if you use WM_BSP_CMD instead of WM_COPYDATA in the send message call BSplayer knows that you are sending a command and not a copydatastruct :wink:
