Question

我想向用户显示一个对话框，说明“这将通过此安装删除”，如果按下“是”或“确定”，则安装可以继续;否则，我想中止它。

因此我定义了一个自定义操作（运行vbscript），如下所示：

<CustomAction Id="ShowUninstallInformationDlg" Impersonate="yes" Return="check" Execute="immediate" BinaryKey="ShowUninstallInformationDlg.vb" VBScriptCall=""/>
<Binary Id="ShowUninstallInformationDlg.vb" SourceFile="c:\myscripts\installer\ShowUninstallInformationDlg.vbs"/>
<InstallExecuteSequence>
  <Custom Action="ShowUninstallInformationDlg" After="FindRelatedProducts">NOT Installed AND NOT PATCH AND NOT MYPRODUCT_ANYVERSION=""</Custom>
</InstallExecuteSequence>

VBSCRIPT（ShowUninstallInformationDlg.vbs）：

'ShowUninstallInformationDlg
Option Explicit

Dim text
Dim productName
Dim rec

productName = Session.Property("ProductName")
text = "The following installations are going to be removed with the installation of " & productName & ":"

If Session.Property("MYPRODUCT_ANYVERSION") <> "" Then
  text = text & "\n    * MyOtherProduct (any version)"
End If

Set rec = Session.Installer.CreateRecord(1)
rec.StringData(0) = text

Session.Message &H0B000034, rec

我使用的“＆amp; H0B000034”作为“Session.Message”参数来自MSDN的示例，请参阅http://msdn.microsoft.com/en-us/library/windows/desktop/aa371672(v=vs.85).aspx。

始终正在执行脚本我的MSI日志中出现以下错误：

错误1720.此Windows Installer程序包存在问题。无法运行此安装所需的脚本。请联系您的支持人员或包装供应商。自定义操作ShowUninstallInformationDlg脚本错误-2147467259，Msi API错误：消息，种类，记录行19，第1列，

我使用Session.Message大量搜索谷歌示例，但没有取得任何成功......有人可以帮忙吗？谢谢！

我使用过以下功能正常

Session.Message &H04000000, rec

请参阅我为其编写的vbs

  Sub LogMessage(msg)

      Dim rec
      Set rec = Session.Installer.CreateRecord(1)
      rec.StringData(0) = "Custom Message : " & msg
      Session.Message &H04000000,rec

  End Sub

在“添加/删除程序”中按下“删除”按钮时，不应显示任何UI。或者，您可以禁用“删除”按钮并启用“更改”按钮。这会调用通常具有Repair |的维护UI体验改变|删除对话框。如果他们选择删除并按下下一步，则可以显示一个丰富的用户界面询问您的问题。

这个脚本通过使用MsgBox而不是“Session.Message”解决了我的问题：

'ShowUninstallInformationDlg
Option Explicit

const vbOKOnly           = 0    'OK button only
const vbOKCancel         = 1    'OK and Cancel buttons
const vbAbortRetryIgnore = 2    'Abort, Retry, and Ignore buttons
const vbYesNoCancel      = 3    'Yes, No, and Cancel buttons
const vbYesNo            = 4    'Yes and No buttons
const vbRetryCancel      = 5    'Retry and Cancel buttons
const vbCritical         = 16   'Critical Message icon
const vbQuestion         = 32   'Warning Query icon
const vbExclamation      = 48   'Warning Message icon
const vbInformation      = 64   'Information Message icon
const vbDefaultButton1   = 0    'First button is default
const vbDefaultButton2   = 256  'Second button is default
const vbDefaultButton3   = 512  'Third button is default
const vbDefaultButton4   = 768  'Fourth button is default
const vbApplicationModal = 0    'Application modal (the current application will not work until the user responds to the message box)
const vbSystemModal      = 4096 'System modal (all applications wont work until the user responds to the message box)

const vbOK     = 1 'OK was clicked
const vbCancel = 2 'Cancel was clicked
const vbAbort  = 3 'Abort was clicked
const vbRetry  = 4 'Retry was clicked
const vbIgnore = 5 'Ignore was clicked
const vbYes    = 6 'Yes was clicked
const vbNo     = 7 'No was clicked

const msiDoActionStatusNoAction      = 0 '&H0
const msiDoActionStatusSuccess       = 1 '&H1
const msiDoActionStatusUserExit      = 2 '&H2
const msiDoActionStatusFailure       = 3 '&H3
const msiDoActionStatusSuspend       = 4 '&H4
const msiDoActionStatusFinished      = 5 '&H5
const msiDoActionStatusWrongState    = 6 '&H6
const msiDoActionStatusBadActionData = 7 '&H7

public function ShowMessage()
  Dim productName
  Dim text
  Dim buttons
  Dim result

  productName = Session.Property("ProductName")
  text = "The following installations are going to be removed from this computer by continuing the installation of " & productName & ":"

  If Session.Property("MYPRODUCT_ANYVERSION") <> "" Then
    text = text & chr(13) & chr(13) & "    * MyOtherProduct (any version)"
  End If 

  buttons = vbExclamation + vbOKCancel
  result = MsgBox(text, buttons, "Dependant Product Installations")

  If result = vbOK Then
    ShowMessage = msiDoActionStatusSuccess
  Else
    ShowMessage = msiDoActionStatusUserExit
  End If
end function
