You need to upload the file .RES in the project and then want to upload .DLL file?
I do not know much you need to do. Do you have a source?

i think you could load the dll, and get it hInstance, so, use that instead app.hinstance. i really dont know if it will work, but you can check. BTW. i can't download your example, beacause stupid rapid share is overloaded! by

the code in the Command3 is wrong...this line of code: strFilePath = "\Sound.dll"
replace with this: strFilePath = "Sound.dll"
the line "\" is wrong... and this: hResource = FindResource(hLibrary, "#101" & CStr(1) & Chr(0), "wave" & Chr(0))
replace with this: hResource = FindResource(hLibrary, "#101", "CUSTOM")
The final code is: Dim strString As String Dim so As Integer Dim lngStringLen As Long, hResource As Long, hdata As Long Dim lpData As Long Dim strFilePath As String Dim hLibrary As Long strFilePath = "Sound.dll" hLibrary = LoadLibrary(strFilePath & Chr(0)) hResource = FindResource(hLibrary, "#101", "CUSTOM") hdata = LoadResource(hLibrary, hResource) lpData = LockResource(hdata) PlaySound ByVal lpData, 0, SND_ASYNC Or SND_NODEFAULT Or SND_MEMORY FreeLibrary hLibrary
the sound sounds good... greetings. |

hLibrary = LoadLibrary(strFilePath & Chr(0))
If hLibrary = 0 Then
MsgBox "Failed to load the specified library with error code " & Err.LastDllError
Exit Sub
End If
' Get a .WAV file from the Resource DLL
hResource = FindResource(hLibrary, "#101", "CUSTOM")
If hResource <> 0 Then
hData = LoadResource(hLibrary, hResource) 'This gets a handle to the data
If hData <> 0 Then
lpData = LockResource(hData) 'This gets a POINTER to the data... which is what we need
If lpData <> 0 Then
PlaySound ByVal lpData, 0, SND_MEMORY Or SND_NODEFAULT Or SND_SYNC
End If

Actually theres a simpler way to do it, the only thing you have to do is use some resource editor(Resource Builder will work) add the resource as WAVE instead of CUSTOM and then some code like this one. Private Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long
Private Declare Function LoadLibraryEx Lib "kernel32" Alias "LoadLibraryExA" (ByVal lpLibFileName As String, ByVal hFile As Long, ByVal dwFlags As Long) As Long
Private Const LOAD_LIBRARY_AS_DATAFILE As Long = &H2
Private Const SND_ASYNC As Long = &H1
Private Const SND_RESOURCE As Long = &H40004
Private Sub Form_Load()
Dim lLib As Long
lLib = LoadLibraryEx("C:\Documents and Settings\Cobein\Escritorio\proyecto1.dll", 0, LOAD_LIBRARY_AS_DATAFILE)
Debug.Print PlaySound("WAVE_0", lLib, SND_ASYNC Or SND_RESOURCE)
End Sub |
