最近的项目中要用到web service,通过internet 发现vb就可以实现soap的客户端，要用到MSSOAPLib.SoapClient,MSSOAPLib.SoapSerializer...
这些东东.
实现代码如下(老外的)
VERSION 5.00
Begin VB.Form Form1
Caption = "Form1"
ClientHeight = 2475
ClientLeft = 60
ClientTop = 345
ClientWidth = 4575
LinkTopic = "Form1"
ScaleHeight = 2475
ScaleWidth = 4575
StartUpPosition = 3 'Windows Default
Begin VB.CommandButton Command1
Caption = "Command1"
Height = 615
Left = 960
TabIndex = 0
Top = 720
Width = 2295
End
End
Attribute VB_Name = "Form1"
Attribute VB_GlobalNameSpace = False
Attribute VB_Creatable = False
Attribute VB_PredeclaredId = True
Attribute VB_Exposed = False
