【问题描述】：
在安装 WiX 期间，我需要有一个 FileBrowseDialog。我制作了自己的自定义对话框，该对话框引发了 OpenFileDialog 并在会话属性中设置了选定的值（找到代码 here）。我需要一种方法来使用选定的完整路径刷新编辑控件。现在，选择文件后，编辑控件保持空白。我如何实现这一目标？我不是 MSI 或 WiX 方面的专家。
Wix 代码：
<UI>
<Dialog Id="DrugsDBFileBrowseDialog" Width="370" Height="270" Title="!(loc.DrugsDBFileDlg_Title)">
<Control Id="BannerBitmap" Type="Bitmap" X="0" Y="0" Width="370" Height="44" TabSkip="no" Text="!(loc.SetupTypeDlgBannerBitmap)" />
<Control Id="BannerLine" Type="Line" X="0" Y="44" Width="370" Height="0" />
<Control Id="Description" Type="Text" X="25" Y="23" Width="280" Height="15" Transparent="yes" NoPrefix="yes" Text="!(loc.DrugsDBFileDlgDescription)" />
<Control Id="Title" Type="Text" X="15" Y="6" Width="200" Height="15" Transparent="yes" NoPrefix="yes" Text="!(loc.DrugsDBFileDlgTitle)" />
<Control Type="Edit" Id="txtDrugsFilePath" Width="270" Height="15" X="22" Y="142" Property="DRUGSDBFILEPATH" Text="[DRUGSDBFILEPATH]" />
<Control Type="PushButton" Id="btnBrowse" Width="56" Height="21" X="300" Y="139" Text="&Browse" >
<Publish Event="DoAction" Value="BrowseDBFile" Order="0">1</Publish>
<Publish Event="SpawnDialog" Value="ValidationErrorDlg" Order="1000">ValidationErrorText</Publish>
</Control>
<Control Type="Text" Id="lblInstructions" Width="290" Height="15" X="26" Y="120" Text="!(loc.DrugsDBFileDlgLabelDescription)" />
<Control Id="BottomLine" Type="Line" X="0" Y="234" Width="370" Height="0" />
<Control Id="Back" Type="PushButton" X="180" Y="243" Width="56" Height="17" Text="!(loc.WixUIBack)" />
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Text="!(loc.WixUINext)" />
<Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56" Height="17" Cancel="yes" Text="!(loc.WixUICancel)">
<Publish Event="SpawnDialog" Value="CancelDlg">1</Publish>
</Control>
</Dialog>
</UI>
自定义操作代码：
[CustomAction]
public static ActionResult BrowseDBFile(Session session)
{
try {
session.Log("Begin OpenFileChooser Custom Action");
var task = new Thread(() => GetFile(session));
task.SetApartmentState(ApartmentState.STA);
task.Start();
task.Join();
session.Log("End OpenFileChooser Custom Action");
} catch (Exception ex) {
session.Log("Exception occurred as Message: {0}\r\n StackTrace: {1}", ex.Message, ex.StackTrace);
return ActionResult.Failure;
}
return ActionResult.Success;
}
private static void GetFile(Session session)
{
OpenFileDialog fileDialog = new OpenFileDialog();
if (fileDialog.ShowDialog() == DialogResult.OK) {
session["DRUGSDBFILEPATH"] = fileDialog.FileName;
}
}
更新
发现解决方案是在执行与浏览按钮相关的操作之前调用 RESET 事件。执行自定义操作后，我还执行了 PUBLISH PROPERTY。往下看。
