wcf 中的 ActiveX 数据对象 (ADO) 在部署后不起作用

发布于 2024-11-09 05:39:10 字数 958 浏览 0 评论 0原文

我在我的 silverlight 应用程序中使用 ActiveX 数据对象 (ADO) 来显示创建数据库连接向导.. 数据链接属性对话框 .. 这是在后台 WCF 服务中创建并显示的。

当我从 Visual Studio 2010 运行它时，它工作得很好。但是当我将它部署在本地 IIS 中时，它没有显示。

我尝试过捕获异常，但没有。

流程就在这里停止（以粗体和斜体标记）。我还在 wwwroot

Log("before adodb"); 中有客户端策略和跨域文件 MSDASC.DataLinks dataLinks = new MSDASC.DataLinks();

            Log("after adodb");
            if (dataLinks == null)
                Log("Data link is null");
            else
                Log("data link isi not null");
            //note that a reference to: 
            //  c:\Program Files\Microsoft.NET\Primary Interop Assemblies\adodb.dll
            //is also required to read the ADODB._Connection result
            ADODB._Connection connection;
            Log("Promting for new connection");
            ***connection = (ADODB._Connection)dataLinks.PromptNew();***
            Log("after new connection");

任何帮助表示赞赏。谢谢。

i am using ActiveX Data Objects (ADO) in my silverlight application to show the create database connectoin wizard .. data link properties dialog box .. this is create and showed in the background WCF service.

this works perfectly fine when i run it from visual studio 2010. but when i deploy it in my local IIS, it does not show up.

i have tried cathing the exception, but there is none.

The flow just stops here ( marked in bold and italics). I also have the client ploicy and crossdomain file in wwwroot

Log("before adodb");
MSDASC.DataLinks dataLinks = new MSDASC.DataLinks();

            Log("after adodb");
            if (dataLinks == null)
                Log("Data link is null");
            else
                Log("data link isi not null");
            //note that a reference to: 
            //  c:\Program Files\Microsoft.NET\Primary Interop Assemblies\adodb.dll
            //is also required to read the ADODB._Connection result
            ADODB._Connection connection;
            Log("Promting for new connection");
            ***connection = (ADODB._Connection)dataLinks.PromptNew();***
            Log("after new connection");
