View 2 RepliesI 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?

public string base64Encode(string sData) { try { byte[] encData_byte = new byte[sData.Length]; encData_byte = System.Text.Encoding.UTF8.GetBytes(sData); string encodedData = Convert.ToBase64String(encData_byte); return encodedData; } catch (Exception ex) { throw new Exception("Error in base64Encode" + ex.Message); } }
I am creating a web site in .Net 3.5 , I am converting the string into Base64String to send it through querystring.The Response.Redirect works fine for smaller string. But if the original string size is 1670,the response.redirect results in error "Page can not be found".item is the string in below code snippet.
byte[] data = Encoding.Default.GetBytes(item);
return Convert.ToBase64String(data)
I am using the following code to decode base 64 and quoted printable encoded messages. It works well for all the charset's except for quoted printable chinese (Charsets: GB18030, GB2312). When I tried to decode, I am getting '?' as output. provide on this code or any other code that decodes all types of encoded string?

i am failing to get the Base64 string and show it as an image in the output pdf file.
I have a signautre canvas that saves the output directly into the sql database.
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.

View 1 RepliesI 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?

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

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.

I need to save more than 20 rows at a time in database, i did it for previous requirement using a loop, provided rows were not exceeding 10.
Now i have rows exceeding more than 20 or 50, how can mass save operation be performed using asp.net web application.
My Asp.Net calls a SQL sproc and returns a XML file as a string. This is what I need to do:
- save that string into memory (as a file);
- pop up a dialog box asking the user which path he would like to save the file;
Any samples out there...how do I achieve this task in Asp.Net C#?
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?
i believe That Saving Files In DataBase is good for Security Issue , But in My Scenario i didnt Care about Secrurity Issue,
i want to ask U guys which Better Save Files into DataBase or save it on Directory on Server, where This Issue Required:
1-(Reduce Load on Server and didnt affect server Memory).
2- Security not important.
if they have the same result i will move to DataBase Saving.
