问题描述
我的Ajax幻灯片在开始时显示一个空白图像，我似乎无法弄清楚如何阻止它发生。文件夹中只有2个图像，但它似乎认为有3个。我认为我可能需要在页面加载上加载图像，或者强制该功能在页面加载时运行。
这是我的代码：
My Ajax Slideshow shows a blank image on start and I can't seem to figure out how to stop it from happening. There are only 2 images in the folder but it seem to think that there are 3. I think that I may need to have the image load on Page Load or maybe force the function to run on page load.
Here is my code:
<body>
<form id="form1" runat="server">
<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</cc1:ToolkitScriptManager>
<asp:Image ID="Image1" runat="server" Height="1615" Width="1050" ImageAlign="Top"/>
<cc1:SlideShowExtender ID="SlideShowExtender" runat="server" TargetControlID="Image1"
SlideShowServiceMethod="GetImages"
AutoPlay="true" PlayInterval="20000" Loop="True">
</cc1:SlideShowExtender>
</form>
<p class="auto-style1"><span class="auto-style3"><strong style="font-size: 36px; font-weight: bold">Welcome to
Center</strong></span></p>
</body>
和我的代码背后是：
and my code behind is this:
Imports System.IO
Imports AjaxControlToolkit
Imports System.Web.Services
Imports System.Web.Script.Services
Imports System.Collections.Generic
Partial Class Breakfast
Inherits System.Web.UI.Page
<WebMethod()> _
<ScriptMethod()> _
Public Shared Function GetImages() As Slide()
Dim slides As New List(Of Slide)()
Dim sPath As String = HttpContext.Current.Server.MapPath("~/ImagesLunch/")
If sPath.EndsWith("\") Then
sPath = sPath.Remove(sPath.Length - 1)
End If
Dim pathUri As New Uri(sPath, UriKind.Absolute)
Dim files As String() = Directory.GetFiles(sPath)
For Each file As String In files
Dim filePathUri As New Uri(file, UriKind.Absolute)
slides.Add(New Slide() With { _
.Name = Path.GetFileNameWithoutExtension(file), _
.Description = Path.GetFileNameWithoutExtension(file) + " Description.", _
.ImagePath = pathUri.MakeRelativeUri(filePathUri).ToString() _
})
Next
Return slides.ToArray()
End Function
End Class
推荐答案
我弄清楚发生了什么。我没有检查文件夹中隐藏的操作系统文件。当我取消选中隐藏操作系统文件时，我在每个文件夹中找到了罪魁祸首，thumbs.db文件。我进入gpedit.msc并找到了禁用将thumbs.db文件放在文件夹中的密钥，并删除了所有图像文件夹中的所有thumbs.db文件。问题解决了，哇哇，我花了3个月的时间来解决这个问题。
I figured out what was happening. I had not checked the folder for hidden operating system files. When I unchecked to hide operating system files I found the culprit, thumbs.db file in each folder. I went into gpedit.msc and found the key to disable the placing of the thumbs.db file in the folder and deleted all the thumbs.db files from all my image folders. Problem solved, woohoo, it only took me 3 months to figure this out.
