各位板上大大好
小弟最近利用VB2010設計了程式 將WEBCAM照到的畫面
顯示在PICTUREBOX上 成功完成
後來在網路上看到鎯頭大的程式碼是關於截取 Web Cam CCD 影像存成圖
試用之後也成功
但將兩組程式結合後capCreateCaptureWindowA好像互相衝突
鎯頭大用的語法如
' 宣告 API
Private Declare Function SendMessageA Lib "user32" _
(ByVal hwnd As Int32, ByVal wMsg As Int32, _
ByVal wParam As Int32, ByVal lParam As Int32) As Int32
Private Declare Function capCreateCaptureWindowA Lib "avicap32.dll" _
(ByVal lpszWindowName As String, ByVal dwStyle As Int32, _
ByVal X As Int32, ByVal Y As Int32, _
ByVal nWidth As Int32, ByVal nHeight As Int32, _
ByVal hwndParent As Int32, ByVal nID As Int32) As Int32
小弟的部分
<Runtime.InteropServices.DllImport("avicap32.dll")> _
Private Shared Function capCreateCaptureWindowA(ByVal lpszWindowName As String, ByVal dwStyle As Integer, ByVal x As Integer, ByVal y As Integer, ByVal nWidth As Integer, ByVal nHeight As Integer, ByVal hWndParent As Integer, ByVal nID As Integer) As Integer
End Function
每次RUN都說我有多個具相同的簽章定義
請各位大大幫忙(跪求)
