编辑:由于 Rob 的回答,我已经更新了下面的代码,现在它可以工作了。
我找到了几个页面来展示如何做到这一点(http://www.cmcrossroads.com/content/view/13160/120/,http://www.mail-archive.com/wix-users@ lists.sourceforge.net/msg05103.html)并查看了 WAI 的源代码(http://wai.codeplex.com/),但无论我尝试什么,我似乎都无法让它在我的安装程序中工作. 如果有人能发现我做错了什么,我将不胜感激。我的对话 WiX 片段如下所示:
<UI>
<Dialog>
...snip...
<Control Id="WebsiteName" Type="ComboBox" ComboList="yes" Sorted="yes" Property="IIS_WEBSITENAME" X="20" Y="73" Width="150" Height="17"/>
...snip...
<!-- We want our custom action to fill in the WebsiteName ComboBox above
however, if no ComboBox entries exist at compile time then the
ComboBox table is not created in the MSI and we can't add to it in
the custom action. So we have this hidden dummy list box to force
the table to appear. -->
<Control Id="DummyComboBox" Hidden="yes" Type="ComboBox" Sorted="yes" ComboList="yes" Property="DUMMYPROPERTY" X="65" Y="60" Width="150" Height="18">
<ComboBox Property="DUMMYPROPERTY">
<ListItem Text="Dummy" Value="Dummy"/>
</ComboBox>
</Control>
</Dialog>
</UI>
<Property Id="DUMMYPROPERTY">Dummy</Property>
<Property Id="IIS_WEBSITENAME"/>
<CustomAction Id="FillWebsiteNameList" BinaryKey="WiXCustomAction.dll" DllEntry="FillWebsiteNameList" Execute="immediate" />
<InstallUISequence>
<Custom Action="FillWebsiteNameList" After="CostFinalize"/>
</InstallUISequence>
我的自定义操作代码是:
[CustomAction]
public static ActionResult FillWebsiteNameList(Session xiSession)
{
xiSession.Log("Begin FillWebsiteNameList");
xiSession.Log("Opening view");
View lView = xiSession.Database.OpenView("SELECT * FROM ComboBox");
lView.Execute();
xiSession.Log("Creating directory entry");
DirectoryEntry lIis = new DirectoryEntry("IIS://localhost/w3svc");
xiSession.Log("Checking each child entry");
int lIndex = 1;
foreach (DirectoryEntry lEntry in lIis.Children)
{
if (lEntry.SchemaClassName == "IIsWebServer")
{
xiSession.Log("Found web server entry: " + lEntry.Name);
string lWebsiteName = (string)lEntry.Properties["ServerComment"].Value;
xiSession.Log("Website name: " + lWebsiteName);
xiSession.Log("Creating record");
Record lRecord = xiSession.Database.CreateRecord(4);
xiSession.Log("Setting record details");
lRecord.SetString(1, "IIS_WEBSITENAME");
lRecord.SetInteger(2, lIndex);
lRecord.SetString(3, lEntry.Name); // Use lWebsiteName only if you want to look up the site by name.
lRecord.SetString(4, lWebsiteName);
xiSession.Log("Adding record");
lView.Modify(ViewModifyMode.InsertTemporary, lRecord);
++lIndex;
}
}
xiSession.Log("Closing view");
lView.Close();
xiSession.Log("Return success");
return ActionResult.Success;
}
以前有两个问题:
1) 上面的代码在自定义操作的运行过程中失败,“函数在执行期间失败。数据库:表更新失败。” - 这是因为索引问题导致代码尝试将字符串写入 int 列。
2)如果我换行
lRecord.SetString(2, lWebsiteName);
至
lRecord.SetString(2, lEntry.Name);
然后查看跟踪,该操作似乎成功,但是当安装程序运行时,组合框没有可供选择的条目。
如果我将组合框更改为硬编码值,一切正常,即使我对 lWebsiteName 的等价物进行硬编码。
