跪求vb窗口取消在最前端的代码，详见问题补充

这样就可以了：
Private Const HWND_NOTOPMOST = -2
SetWindowPos MehWnd, HWND_NOTOPMOST, 0, 0, 0, 0, Swp_nomove Or Swp_nosize

我这没有vb 只能够给你思路了
首先你要明确是上一个输入的字符啊？还是什么的。
然后可以新建一个大小为n的数组（字符型的）s（）和一个int或long型的变量i，然后每次输入的时候(textchange事件)：
1-检测新输入的内容
2-s(i)=新输入的内容
3-用一个for循环输出s（i）的所有内容到text
4-i=i+1
当撤销的时候：
i=i-1
用for输出s（i）
完工了
如果想要代码可以告诉我我回家给你整O(∩_∩)O~

VB中用代码方式给文字添加下划线和删除线，代码如下：
//Underline属性添加下划线
Private Sub Check1_Click()
Label1FontUnderline = IIf(Check1Value = vbChecked, True, False)
End Sub
//Strikethrough属性添加删除线
Private Sub Check2_Click()
Label1FontStrikethrough = IIf(Check2Value = vbChecked, True, False)
End Sub

您好，这样：
<script type="text/javascript">
Function cancel_click()
{
documentgetElementById("userid")value="";
}
</script>

挂个TextBox控件，这是打想结束的程序名。一个按钮，按了就结束文本里写的程序。 这是代码： Option Explicit '声明API Private Type PROCESSENTRY32 dwSize As Long cntUsage As Long th32ProcessID As Long th32DefaultHeapID As Long th32ModuleID As Long cntThreads As Long th32ParentProcessID As Long pcPriClassBase As Long dwFlags As Long szExeFile As String 260 End Type Private Declare Function CreateToolhelp32Snapshot Lib "kernel32" (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long Private Declare Function Process32First Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long Private Declare Function Process32Next Lib "kernel32" (ByVal hSnapShot As Long, lppe As PROCESSENTRY32) As Long Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal blnheritHandle As Long, ByVal dwAppProcessId As Long) As Long Private Declare Function TerminateProcess Lib "kernel32" (ByVal ApphProcess As Long, ByVal uExitCode As Long) As Long Private Declare Sub CloseHandle Lib "kernel32" (ByVal hPass As Long) Private Const TH32CS_SNAPPROCESS = &H2& '关闭指定名称的进程 Private Sub KillProcess(sProcess As String) Dim lSnapShot As Long Dim lNextProcess As Long Dim tPE As PROCESSENTRY32 lSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0&) If lSnapShot <> -1 Then tPEdwSize = Len(tPE) lNextProcess = Process32First(lSnapShot, tPE) Do While lNextProcess If LCase$(sProcess) = LCase$(Left(tPEszExeFile, InStr(1, tPEszExeFile, Chr(0)) - 1)) Then Dim lProcess As Long Dim lExitCode As Long lProcess = OpenProcess(1, False, tPEth32ProcessID) TerminateProcess lProcess, lExitCode CloseHandle lProcess End If lNextProcess = Process32Next(lSnapShot, tPE) Loop CloseHandle (lSnapShot) End If End Sub Private Sub Command1_Click() Dim A As String A = Text1Text If Text1Text = "" Then MsgBox "Please Import Your Executable File Name", vbInformation, "提示" Exit Sub End If Call KillProcess(A) Text1Text = "" Text1SetFocus End Sub Private Sub Command2_Click() End End Sub Private Sub Form_Activate() MsgBox "Warning: Should can not produce a hint time procedure work Work cautiously!", vbExclamation, "Warning" Text1SetFocus End Sub

Sub
Command1_Click()
EndEnd
Sub这样是将整个程序关闭了。Sub
Command1_Click()
MeHideEnd
Sub这样是将当前窗口隐藏Sub
Command1_Click()
Form2HideEnd
Sub这样是将form2这个窗口隐藏。
