I found this code on this site in another thread and tried it. I am passing a string of a web url such as [URL] .... and it gives me this error. How can I pass in the URL without this error?
Code:
Private Sub saveURLToImage(ByVal url As String)
If Not String.IsNullOrEmpty(url) Then
Dim content As String = ""
Dim webRequest__1 As System.Net.WebRequest = WebRequest.Create(url)
Dim webResponse As System.Net.WebResponse = webRequest__1.GetResponse()
I'm having trouble getting a form working with MVC2. As soon as I change the form element to use 'enctype="multipart/form-data"' I get errors when submitting it. The code I've got creating the form is as follows:
[Code]....
With several form text field and a file upload being the only fields. Nothing too complicated!The action method that handles the form submission is as follows:
[Code]....
It's nothing too complicated either. The code that I've commented out would have inserted the image into the database, but I commented it out to see if it was causing the problem, but it's not.The error I'm getting is as follows:
Server Error in '/' Application.
Invalid character in a Base-64 string.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.FormatException: Invalid character in a Base-64 string.Source Error: [Code]....

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927
Obviously something is going terribly wrong here, but I'm at a complete loss as to what it is. The form works fine if I get rid of the multipart bit in the form element, but then of course it doesn't upload the image. I also get the error regardless of whether I've actually selected an image to upload, so it's not the actual image causing the error.
My application is very big one. I m getting this error. I dont know where it is throwing.
I m unable to find this error. Can anyone help me and tell me the scenarios when will this exception comes.
The Stack Trace is throwing this message

I am developing a C# VS 2008 / SQL Server 2005 Express website application. I have tried some of the fixes for this problem but my call stack differs from others. And these fixes did not fix my problem. What steps can I take to troubleshoot this?

I think it has to do with my commit, hence how I do include commit in an update directly in the asp.net side.
The top imageUrl declartion is taking in a Base64 image string, and I want to convert it into an image. I think my set of code only works for images like "www.mysite.com/test.jpg" not for a Base64 string.
I do need a working ASP.NET C# code to replace characters in a string.
My following code works fine but in case of input "a" it gives me an output as "678d", but in case of input "c" the output is correct as it is i.e. "8d"... Here it automatically replaces the rest values too. I can see the code is executing in a step by step process... This results me to get an overloaded output.
am working on a application, there i need to find that whether there are any Unicode character in a string or not, I have to check a string for Unicode character but i don't know how to find out Unicode character from any string.
i want to take a string and check the first character for being a letter, upper or lower doesn't matter, but it shouldn't be special, a space, a line break, anything
