Hi All,

..NET application does not give correct result when I used following API
function .

{
Declare Function waveInGetNumDevs Lib "winmm.dll" () As Long

MsgBox(waveInGetNumDevs)

}

..NET gives it as 855400533......

VB6 gives it 1
VC++6 gives it 1

So why .NET is not giving correct one.

Thanks in advance

You are using the wrong function signature. In .Net, a long is 64 bits
whereas an Integer is 32. Your return type should be Integer, not Long.

To send me an E-mail, remove the "[", "]", underscores ,lunchmeat, and
replace certain words in my E-Mail address.

declare the function as:
Declare Function waveInGetNumDevs Lib "winmm.dll" () As Integer

Longs from VB6 convert to Integers in .NET (32-bit). Longs in .NET are
64-bit.

'Long' maps to 'Int64' which is a 64-bit datatype. Use '...As Int32'
instead.
