获取ToolTipText内容_VB源代码

获取ToolTipText内容

本篇内容提供一个获取ToolTipText内容的通用模块，并提供一个使用范例。

请按以下四个步骤进行：

一、把下面内容保存为Project1.vbp

Type=Exe

Form=Form1.frm

Module=mTray; mTray.bas

IconForm=\"Form1\"

Startup=\"Form1\"

HelpFile=\"\"

Title=\"Project1\"

ExeName32=\"GetToolTipText.exe\"

Command32=\"\"

Name=\"Project1\"

HelpContextID=\"0\"

CompatibleMode=\"0\"

MaxNumberOfThreads=1

[MS Transaction Server]

AutoRefresh=1

二、把下面内容保存为Form1.frm

VERSION 5.00

Begin VB.Form Form1

BorderStyle Caption ClientHeight ClientLeft ClientTop ClientWidth LinkTopic MaxButton MinButton ScaleHeight = 3 'Fixed Dialog

= 0 'False

= 3510

=

ScaleWidth = 3525

ShowInTaskbar = 0 'False

StartUpPosition = 3 '窗口缺省

Begin VB.CommandButton Command1

Caption = \"获取xp“开始”按钮提示内容\"

Height = 1215

Left = 840

TabIndex = 0

Top = 1920

Width = 1815

End

End

Attribute VB_Name = \"Form1\"

Attribute VB_GlobalNameSpace = False

Attribute VB_Creatable = False

Attribute VB_PredeclaredId = True

Attribute VB_Exposed = False

Option Explicit

Dim sTrayList As Variant

i = FindWindow(\"Shell_TrayWnd\

If i = 0 Then Exit Sub

i = FindWindowEx(i, 0, \"Button\开始\")

sTrayList = GetTrayList(i)

For i = 0 To UBound(sTrayList)

If sTrayList(i) <> \"\" Then

MsgBox \"“开始”按钮提示内容是：\" & sTrayList(i)

End If

Next

End Sub

三、把下面内容保存为mTray.bas

四、把以上三个文件放在同一个目录下，然后双击鼠标运行Project1.vbp即可运行form1并看到效果。
