Hi,

I am currently writing a front-end for my CarPC, but cannot get the current frequency form radiator. I can control every part of it apart from getting the Frequency from it. I am coding in Visual Basic .NET 2005. I looked around on the internet and it looks like GetWindowText.

When you change the frequency in Radiator, the windows title changes and has the frequency in it....


eg. 99.30 FM - Radiator (Muted)


I have used the code below to get the windowtext, so I can take the first part of the returned string to give me the frequency........




Public Function Radiator_GetFrequency() as String

Dim buf As String
Dim Title As String
Dim Length As Integer

Length = GetWindowTextLength(hWndRadiator)
buf = Space$(Length)
Length = GetWindowText(hWndRadiator, buf, Length + 1)
Title = buf.Substring(0, 5)

Return Title

End Function



...but all I get back from the function is the string "Radiator", why is this, has anybody else managed to get the frequency from Radiator?

Thanks for any help

After a lot of searching on the internet I have found a way to get the frequency. The actual window that contains the frequency information is the parent to the Radiator window. You simply use the GetWindowLong to find the parent window handle and then use GetWindowText to get its title.

Hope this is some help to someone.
