MsgBox不够大的文本
我有一个string（味精）是非常长的项目列表。 我需要把它放在一个msgbox中，但它不足以显示整个文本。 有没有其他的select呢？
谢谢！
消息框function是VBA的内置function，不能超过1024个字符。 您只能创build自己的UserForm或其他select…如打开和写入未保存的记事本实例…
一个所有的API解决scheme打开记事本，并写下您的消息…注：如果您运行的VBA 7.0（Office 2010），那么你将不得不添加PtrSafe每个声明声明后…
在模块的顶部粘贴API声明和全局variables

上面的代码可能看起来很麻烦或者更复杂，但是如果使用其他的方法，它可能会更加可靠和高效地工作。
下面的函数将使用MS剪辑工具将您的消息复制到剪贴板，打开记事本，然后将剪贴板内容（您的消息）粘贴到记事本中…这样，您不必将任何内容保存到文件中，closures…或者你可以保存它，如果你select。
Option Explicit Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long) Sub Print2Notepad(strMessage) Dim oShell As Object, oExec As Object, oIn As Object Set oShell = CreateObject("WScript.Shell") Set oExec = oShell.Exec("clip") Set oIn = oExec.StdIn oIn.WriteLine strMessage oIn.Close Do While oExec.Status = 0 Sleep 100 Loop Set oIn = Nothing Set oExec = Nothing oShell.Run "Notepad", 1, False Sleep 250 oShell.SendKeys "^v" End Sub Sub test() Call Print2Notepad("This is a test message") End Sub
如果您需要，也可以在记事本打开的情况下添加额外的例程以“hibernate”以暂停代码…请参见下文
Sub Print2Notepad_WaitTillClose(strMessage) Dim oShell As Object, oExec As Object, oIn As Object Dim iPID As Variant, oNotepad As Object Set oShell = CreateObject("WScript.Shell") Set oExec = oShell.Exec("clip") Set oIn = oExec.StdIn oIn.WriteLine strMessage oIn.Close Do While oExec.Status = 0 Sleep 100 Loop Set oIn = Nothing Set oExec = Nothing iPID = oShell.Exec("Notepad").ProcessID Sleep 500 oShell.SendKeys "^v" Do Sleep 500 Set oNotepad = Nothing On Error Resume Next Set oNotepad = GetObject("winmgmts:root\cimv2:Win32_Process.Handle='" & iPID & "'") On Error GoTo 0 Loop While Not oNotepad Is Nothing ' For Example only - Delete Below Line MsgBox "You Closed Notepad" End Sub
编辑：我只是意识到，我写了上面的代码工作的VBScript …因为这是Excel，如果您想要查看其他方法将内容复制到剪贴板，而不使用WshShell.Exec方法; 你也可以尝试：
Dim DataObj As New MSForms.DataObject Dim S As String S = "Hello World" DataObj.SetText S DataObj.PutInClipboard
要在代码中使用DataObject，您必须设置对Microsoft Forms 2.0对象库的引用。 这也可以通过创build一个用户窗体，然后删除它…参考将保持（Excel 2007）。
对于额外的剪贴板API和代码，请看看：
1） http://www.cpearson.com/excel/Clipboard.aspx 2） http://msdn.microsoft.com/en-us/library/office/ff192913.aspx 3） http://msdn.microsoft。 COM / EN-US /库/窗/台式机/ ms648709％28V = vs.85％29.aspx
还有其他可能的方法，但我认为这是最稳定和可靠的。 我将以这样的方式保留代码，以便VBA和VBScript都能正常工作
使用文本框。 我知道ActiveX文本框甚至可以分配滚动条。
