DotNetNuke:FAQ[随笔]

我想应该也为自己建立一个FAQ随笔，昨天刚刚解决了心中的疑问，结果早上过来又忘记了昨天是怎么解决了，又浪费了好几个小时，哎！我也不知道该随笔何时会更新，反正有疑问并解决之后就会FAQ

一，何时使用skins目录下的default.ascx或是admin.ascx

这二个自定义控件的区别在admin.ascx只有contentpane,而default.aspcx有leftpane,rightpane,contextpane,它们的是如何载入？？

        ' returns a boolean value whether the tab is an admin tab
        '返回的位置是否是admin的位置
        Public Function IsAdminTab()Function IsAdminTab(ByVal intTabId As Integer, ByVal intParentId As Integer) As Boolean

            ' Obtain PortalSettings from Current Context
            '获取portaSettings的HTTPCONTEXT请求信息
            Dim _portalSettings As PortalSettings = CType(HttpContext.Current.Items("PortalSettings"), PortalSettings) 'AdminTabId为TabID，并且条件是admin

            Return (intTabId = _portalSettings.AdminTabId) Or _
                    (intParentId = _portalSettings.AdminTabId) Or _
                    (intTabId = _portalSettings.SuperTabId) Or _
                    (intParentId = _portalSettings.SuperTabId)

        End Function

上面的代码中_portalSettings.AdminTabId是admin菜单位置，_portalSettings.SuperTabId是host菜单位置，调用的存储过程是：DNN_GetPortalSettings

二，模块的最大化/最小化
第一次看见这个也有点好奇，但分析完之后你就会发出感叹：原来是这样的～
最大化/最小化它实际上是在容器中产生的，Containers/Visibility.ascx
单击最大化图标时,隐藏名称为ModuleContent 的pane控件，并将值保存到cookie当中，并显示小图标。相反，就显示图标，并保存值，当你第一次载入控件的时候，判定该保存的cookie的值，进行是否显示，或隐藏～

三，垂直菜单的SKIN

到现在我还没瞧见过垂直的菜单。呵呵，不过今天在论坛里发现这个问题，vertical  menu

六，Logo File Types（谁有告诉我Admin Settings-> Logo dropdown list box）

In the components\globals.vb, there is a routine that specifies the available image types. 

       Public Const glbImageFileTypes As String = "jpg,jpeg,jpe,gif,bmp,png"

And the routine that the sitesettings calls is GetFileList, also in the Globals.vb

 

 ' get list of files from folder matching criteria

        Public Function GetFileList()Function GetFileList(Optional ByVal PortalId As Integer = -1, Optional ByVal strExtensions As String = "", Optional ByVal NoneSpecified As Boolean = True) As ArrayList

            Dim arrFileList As New ArrayList



            If NoneSpecified Then

                arrFileList.Add(New FileItem("", "<None Specified>"))

            End If

            Dim objFiles As New FileController

            Dim dr As IDataReader = objFiles.GetFiles(PortalId)

            While dr.Read()

                If InStr(1, strExtensions.ToUpper, dr("Extension").ToString.ToUpper) <> 0 Or strExtensions = "" Then

                    arrFileList.Add(New FileItem(dr("FileName").ToString, dr("FileName").ToString))

                End If

            End While

            dr.Close()

            GetFileList = arrFileList

        End Function

The portals\admin\sitesettings.ascx.vb has code to retrieve it.

 

 ' load the list of files found in the upload directory

                    Dim ImageFileList As ArrayList = GetFileList(intPortalId, glbImageFileTypes)

                    cboLogo.DataSource = ImageFileList

                    cboLogo.DataBind()

                    cboBackground.DataSource = ImageFileList

                    cboBackground.DataBind()
