Trying to create a FIle Upload page using

Can someone give me some advise on what I may be doing wrong in creating the file upload below. I'm trying to create a file upload page for a site that I'm developing, and whenever I click the  "Upload Image Button" nothing happens....the image that I'm trying to upload doesn't appear as expected.

I have included the VB.NET code below.

You have not given HTML here. I guess you are not posting page as per the RFC standard. You need to use


In form tag

I hope this helps

Posting filepath in file upload control in .NET to the next page and uploading the file from second page
In our application (using C# .NET) there is a form with file upload options. After filling up the form details, the summary of the details need to be shown in the next page before committing the information into the database. Right now, Server.Control is used to transfer the contents to the next page and the form details are retrieved using Request.Form["control id"]. But this is not working for File upload control alone.File upload can not be done in the first page itself, as the foreign key in File upload table gets updated only in second page after confirmation. Therefore, is th...

Both C# ASPX pages and VB.NET ASPX in single VB.NET Web Applcation Template
Hi.. Is it possible to have both c# pages and VB pages in same Webapplication, what i chose is VB.NET Web application Template. With Thanks, Jaya.... I don't see why you couldn't, but for the sake of consistency I don't know why you would want to do this. When you choose a C# or VB.NET application template(I'm assuming you're using VS or WebMatrix), it simply creates a .aspx file that includes a page directive that specifies the page language. If you created a C# template but want to use VB.Net instead, you need to go from: <%@ Page Language="C#" .... to...

Functions in Web Pages using VB.NET

For example, if I have 4 ASPX pages and will use the same function, where or what part of the web page can I place this function or do I need to have that function in each of the ASPX page?
