[英]WiX Toolset: How to store a file from Binary Table in a Custom Action
[英]WiX Toolset Custom Action Fails When Modifying Database
我一直在瘋狂地試圖弄清楚為什么視圖沒有更新。 從網上看到的所有帖子中,我認為我做得對,但是我一直收到Null錯誤。 如果我嘗試使用session.Database.FilePath以這種方式加載數據庫,則說FilePath為null。 視圖本身正在返回虛擬行,因此數據庫位於其中。 真是奇怪
以下是物業
<Property Id="IIS_SITE" />
二進制和自定義動作
<CustomAction Id="UpdateComboBoxes" DllEntry="UpdateComboBoxes" BinaryKey="UpdateComboBoxes" Execute="immediate" Return="check" />
<Binary Id="UpdateComboBoxes" SourceFile="..\ProjectName.CustomActions\bin\Release\ProjectName.CustomActions.CA.dll"/>
安裝UI序列
<InstallUISequence>
<Custom Action="UpdateComboBoxes" Before="CostFinalize"></Custom>
</InstallUISequence>
控制
<Control Id="IisSite" Type="ComboBox" Sorted="yes" ComboList="yes" Property="IIS_SITE" X="45" Y="85" Width="220" Height="18" >
<ComboBox Property="IIS_SITE" >
<ListItem Text="Dummy" Value="Dummy"/>
</ComboBox>
</Control>
自定義動作
[CustomAction]
public static ActionResult UpdateComboBoxes(Session session)
{
session.Log("Begin Custom Action UpdateComboBoxes");
try
{
session.Log(string.Format("Database Location is: {0}", session.Database.FilePath));
var database = session.Database;
using (var view = database.OpenView("SELECT * FROM ComboBox WHERE Property = 'IIS_SITE'"))
{
view.Execute();
session.Log("Executed view");
var isReadOnly = database.IsReadOnly;
session.Log(string.Format("Database is read only: {0}", isReadOnly));
session.Log(string.Format("# of rows in ComboBox Table: {0}",
view.Database.CountRows("ComboBox", "Property = 'IIS_SITE'")));
using (var serverManager = new ServerManager())
{
session.Log("Accessed Server Manager");
var index = 1;
var rowIndex = 1;
session.Log(string.Format("Going through {0} sites", serverManager.Sites.Count));
foreach (var site in serverManager.Sites)
{
if (!string.IsNullOrEmpty(site.Name))
{
session.Log(string.Format("Site # {0} {1}", index, site.Name));
var record = session.Database.CreateRecord(4);
//Property
record.SetString(1, "IIS_SITE");
//Order
record.SetString(2, rowIndex.ToString());
//Value
record.SetString(3, site.Name);
//Text
record.SetString(4, site.Name);
session.Log(string.Format("Modifying the view for site # {0}", index));
view.Modify(ViewModifyMode.InsertTemporary, record);
}
session.Log("Incrementing index");
index++;
rowIndex++;
}
}
session.Log("Closing the view");
}
}
catch (Exception e)
{
session.Log(string.Format("ERROR in UpdateComboBoxes: {0}", e.Message));
session.Log(e.StackTrace);
var inner = e.InnerException;
if(inner != null)
{
session.Log(string.Format("{0}{1}", "\t", inner.Message));
session.Log(string.Format("{0}{1}", "\t", inner.StackTrace));
}
while ((inner = inner.InnerException) != null)
{
session.Log(string.Format("{0}{1}", "\t", inner.Message));
session.Log(string.Format("{0}{1}", "\t", inner.StackTrace));
}
return ActionResult.Failure;
}
return ActionResult.Success;
}
我得到的錯誤:
MSI(c)(B0!F4)[14:46:40:369]:注意:1:2259 2:3:3:4:
UpdateComboBoxes中的錯誤:函數在執行期間失敗。 VideoQuestionInstaller.CustomActions.CustomActions.UpdateComboBoxes(Session session)上的Microsoft.Deployment.WindowsInstaller.View.Modify(ViewModifyMode模式,記錄記錄)在自定義操作上引發的異常:System.Reflection.TargetInvocationException:調用。 ---> System.NullReferenceException:對象引用未設置為對象的實例。 在VideoQuestionInstaller.CustomActions.CustomActions.UpdateComboBoxes(Session session)-內部異常堆棧跟蹤的結尾--在System.RuntimeMethodHandle.InvokeMethod(Object target,Object arguments,Signature sig,Boolean構造函數)在System.Reflection.RuntimeMethodInfo。 Microsoft.Deployment.WindowsInstaller.CustomActionProxy.InvokeCustomAction(Int32 sessionHandle,String。 entryPoint,IntPtr remotingDelegatePtr)
我查了一下,錯誤2259表示數據庫更新失敗,這很明顯,因為錯誤之前的最后一個日志是:修改站點#1的視圖。
有人對我做錯了什么有什么想法,為什么ComboBox數據庫沒有更新?
提前致謝!
沒關系,我知道了問題所在。 這是我的解決方法:
我添加了另一個隱藏的控件,以便創建組合框表,而不必將假值放入要使用的實際組合框中。
<Property Id="HIDDEN_IIS_SITE" />
<Control Id="DummyComboBox" Hidden="yes" Type="ComboBox" Sorted="yes" ComboList="yes" Property="HIDDEN_IIS_SITE" X="45" Y="85" Width="220" Height="18" >
<ComboBox Property="HIDDEN_IIS_SITE" >
<ListItem Text="Dummy" Value="Dummy"/>
</ComboBox>
</Control>
然后,我更改了自定義操作,以使其獲得現有行的實際數量,然后在添加記錄時將其添加到該行中,以便使用訂單的正確編號
[CustomAction]

{
session.Log("Begin Custom Action UpdateComboBoxes");

{
view.Execute();
session.Log("Executed view");
var index = view.Database.CountRows("ComboBox", "Property = 'IIS_SITE'");
using (var serverManager = new ServerManager())
{
foreach (var site in serverManager.Sites)
{
if (!string.IsNullOrEmpty(site.Name))
{
var record = session.Database.CreateRecord(4);
//Property
record.SetString(1, "IIS_SITE");
//Order
record.SetString(2, (++index).ToString());
//Value

session.Log("Inserted new record");
}
}

session.Log(string.Format("{0}{1}", "\t", inner.StackTrace));
}
return ActionResult.Failure;
}
return ActionResult.Success;
