I need a query which converts base64 to normal string . I am storing my value as base64 in the DB . How can I convert it to normal text from query
View 7 RepliesI 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.

View 1 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?

I'm sure i've got this entirely backwards. However if I change the NULL value in the stored procedure with some string value (eg."Donkeys") it pulls all the values that contain "Donkeys" into the datalist on my results page.

I want to know how can I check is decrypted string equals to plain text before encrypting?

View 2 RepliesIm trying to test my extension method that converts a list of strings in a string comma separated:
public static class Extensions
{
public static string ToCommaString<T>(this IList<T> input)
{
StringBuilder sb = new StringBuilder();
foreach (T value in input)
{
sb.Append(value);
sb.Append(",");
}
return sb.ToString();
}
public void TestExtension()
{
IList test=new List<string>();
//test.ToCommaString doesnt appear
}
}
The issue is that in the method TestExtension i cant use ToCommaString method. Do you know what's happening?
Could i make available for all my web application this extension method registering in web.config or something similar?
In my application at some places we have used ObjectDataSource and at other normal method calls to retrieve data.My question is then what exactly are the benefits of using ObjectDataSource ?In the example below "CODE ONE" makes a call to the Business Layer and then Binds the results to the Grid abd "CODE TWO" is using ObjectDataSource to do the same.Then how is ObjectDataSource better?
SuitableApplicant sa = new SuitableApplicant();
IList<HD.Recruitment.SuitableApplicant> list = new List<HD.Recruitment.SuitableApplicant>();
list = HS.Recruitment.RecruitmentService.GetSuitableAppls();
GridView1.DataSource = list;

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 am in a situation where I want a new query on clicking the next page(in grid paging). I have some specific entries in my DB against every year. So suppose when first the grid loads it displays the records of 2010 and when I click the page 2 (in page number area) it displays the records of 2009 and similarly on page 3 it displays 2008 etc...
If it is possible what the approaches I can adopt?
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.

View 5 RepliesI've got a query such as
Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select
which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE
However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?
I have a problem to write a string to a LinkButton that is located inside a GridView1. Now the hiarchy of controls is like this to understand how to Find this control:
TabContainer0 TabPanel5 TabContainer1 TabPanel7 Panel8 GridView1 LinkButton1 So LinkButton1 that we want to write a string to is located in a GridView1 which is located in Panel8 which is located in TabPanel7 that is located in TabContainer1 that is located in TapPanel5 that is located in TabContainer0.
So below is my code but no string is written to that linkButton, so I wonder if I miss something basic out here?
