How To Encode An Url As Base64 String

Sep 16, 2010

I know that I could use HttpServerUtility.UrlTokenDecode Method to do the job. But the problem is that I am using .NET 1.1 and this method is only supported in .NET 2.0+. Also I found that Convert.ToBase64String method is not an option because of the differences addressed here. So what other options do I have? Do I have to write my own converting method?

How To Save Data In SQL Server Database And Then Sending The Email Later

Sep 29, 2010

I have a data entry and editing form and in every data entry or update event, I have to send an email to a dynamic list of recipients. I have been sending the email as soon as the user clicks the save or edit buttons but am thinking of first saving the data to the database, and then sending the email later. I want to do this partly to improve the response time of the application as the email sending tends to take a long time than desired.

Forms Data Controls :: Save Images To Database Or To Server

Jun 14, 2010

I have been debating back and forth between using a database or the file server to store images for users. Finally when I decided to use the file server I found it difficult. What I am trying to do is give a user the option to save multiple profile pictures. I have looked all over for tutorials on how to save to the file server but could find nothing related. Essentially what I would like to do is create folders for each user and their images. I am having no luck. Does anyone have example code or links to what I am looking for?

Web Forms :: Error - "Invalid Characters In Base64 String"

Sep 15, 2010

I'm running into following error: "The viewstate is invalid for this page and might be corrupted." "Invalid character in base64 string." Only with IE 8.0. Firefox works fine. The persisted view state is

"/wEPDwULLTE2OTU5NzE1MjYPZBYCAgMPZBYCAgEPZBYCAgMPZBYCZg9kFgQCBQ8WAh4FVmFsdWUFCGRpc2FibGVkZAIHDxYCHwAFCGRpc2FibGVkZGSt4I2szqsXGPwfecanpFW+cIZNhQ==,/wEPDwULLTE2OTU5NzE1MjYPZBYCAgMPZBYCAgEPZBYCAgMPZBYCZg9kFgQCBQ8WAh4FVmFsdWUFCGRpc2FibGVkZAIHDxYCHwAFCGRpc2FibGVkZGSt4I2szqsXGPwfecanpFW+cIZNhQ=="

i.e. two identical parts separated by a comma. I'm using a form with both jQuery and UpdatePanel. I've inspected the __VIEWSTATE hidden field before the post __doPostBack and $I.System.InvokePageMethod. In both cases the viewstate does NOT contain the comma. where the field gets doubled up with the comma inserted? Or how to fix.

Save String To Client With Open/Save Dialog?

Aug 8, 2010

I am using the following code to write the contents of a string (converted to a byte array) to the client in ASP.NET/C#

byte[] data = StrToByteArray(strData);
Response.ClearContent();
Response.AppendHeader("content-length", data.Length.ToString());
Response.ContentType = "text/plain";
Response.AppendHeader("content-Disposition", "attachment;filename=" + fileName);
Response.BinaryWrite(data);
Response.Flush();

fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?

Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?
