vb Image 图片控件 网络

如何在Image 图片控件显示网上的图片
?

Answer 1

可以用OleLoadPicturePath 这个API来实现。

Private Type TGUID
Data1 As Long
Data2 As Integer
Data3 As Integer
Data4(0 To 7) As Byte
End Type

'// 用来加载Internet上的图片
Private Declare Function OleLoadPicturePath Lib "oleaut32.dll" (ByVal szURLorPath As Long, ByVal punkCaller As Long, ByVal dwReserved As Long, ByVal clrReserved As OLE_COLOR, ByRef riid As TGUID, ByRef ppvRet As IPicture) As Long

'// 从Internet上加载图片
Public Function LoadPicture(ByVal strFileName As String) As Picture
Dim IID As TGUID
With IID
.Data1 = &H7BF80980
.Data2 = &HBF32
.Data3 = &H101A
.Data4(0) = &H8B
.Data4(1) = &HBB
.Data4(2) = &H0
.Data4(3) = &HAA
.Data4(4) = &H0
.Data4(5) = &H30
.Data4(6) = &HC
.Data4(7) = &HAB
End With

On Error GoTo LocalErr

OleLoadPicturePath StrPtr(strFileName), 0&, 0&, 0&, IID, LoadPicture
Exit Function
LocalErr:
Set LoadPicture = VB.LoadPicture(strFileName)
Err.Clear
End Function

Private Sub Command1_Click()
Image1.Picture = LoadPicture("https://gss0.bdstatic.com/70cFsjip0QIZ8tyhnq/img/logo-zhidao.gif")
End Sub

Answer 2

image控件不能直接显示网上图片吧.
用webbrowser控件显示很方便的.如：
WebBrowser1.Navigate "http://www.baidu.com/search/img/rss_xml.jpg"
