问题 When you create the Register Control for the SqlMembersipProvider nothing happens if they register and the username or email is in use.

问题 I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup.

问题 I'm having real troubles passing form data from a posting page made up of User Controls. I posted this question before, here, Getting form field names on Submit when form is user control but the answers have not solved my problem, or I have mis-understood them. Let me try explaining what I am doing more clearly. I have a page which displays a form to the user. The form is made of several sections, but for simplicity we'll say there are two. Each of these sections is a User Control, thus the

问题 I've got an web app in ASP.NET 2.0 in which I need to do paging. My method of data access is to pull a DataSet out of a database call, then convert that to a List<Foo> (where Foo is my type I'm pulling out of the DB) and bind my GridView to it. My reason for this is that I didn't want to be having to use string indexers on DataTables all through my application, and that I could separate the display logic from the database by implementing display logic as properties on my classes. This also

问题 The same code runs in Windows 7 32 bit. But fails in windows 8 64 bit. Any ideas? Thanks 回答1: I just resolved it. This application requires 32-bit mode where as the IIS in my Windows 8 machine runs in 64-bit mode by default. I had to set Enable 32-bit Applications to true for the AppPool this application is using. and it was not failing on a specific line of code. The exception was thrown somewhere between Application_BeginRequest and Session_Start 来源： https://stackoverflow.com/questions

问题 I've noticed as my website gets bigger and bigger, the time my laptop takes to display my page is much longer then say a new projects with minimal references. I think there are two variables at play that affect ASP.NET warm-up time: The quantity of external references The time it takes for a worker process to new() up each instance per worker process Additional time for the WCF objects as the ServiceHost may be in an external DLL First, are those the correct variables to take into account

问题 I am using ASP.NET to read the data in the excel file. I am using a file upload control to read the file. I am able to read the data from the file in my local machine, but after deploying my code in the server, when I try to read the file from the client machine, I am getting an exception. FileUpload1.PostedFile.FileName is throwing the exception in the server. The exception message is: 'D:\path in client machine\MyExcel.xls' could not be found. Check the spelling of the file name, and verify

问题 I tried using the IHttpModule and managed to convert the urls just fine, but all of my images returned path error (all going through the new url directory). whats the solution? 回答1: You need to make sure that you use the "~/" path notation on your images and make sure that they are all server controls with runat='server'. Otherwise the images urls won't get rewritten. For example if you have a page that gets rewritten from: /Item/Bicycle.aspx to /Item.aspx?id=1234 Then what will happen is

问题 I have a free hosting service that is stuck in ASP.NET 2.0. Additionally, it constrains users to only inline versions (no codebehind). However, it does allow references to custom components. I have built an inline .asmx and would, ideally, like to 'include'/'use' a component I've built. How do I do this inline? I've tried 'using [Namespace]', but get a compilation error. I've also tried using, in the WebMethod [Namespace of Component].[Method] as well. Again, this produces a compilation error
