Since I'm new to coding and I'm trying to understand why here is a little more detail on the question.If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.

View 1 RepliesI have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
I have a 15 digit string to encrypt.
I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.
I'm trying to convert a string to decimal but I get this exception:
Exception Details:

I am making a form that contains a lot of User Controls, each User Control is part of the form (contains TextBox, ComboBox etc). User will use the form to update their information. At end of submission, I need to display the original data and the data that the user have entered. I wonder if is possible that I can replace the input control (TextBox etc) to Label? So I can just simply use the same user control, then convert each of the input control to label to display the data... (I just don't really want to use readonly or disable) Note: I used different dataset to map each of the User Control data. What I was thinking to do is like to get the input control from Page.Controls:
aInputControl = new Label();
or...
Page.Controls.Remove(aInputControl);
Then somehow add new Label in same position in the page. But I have no idea how...can't think of anything except add another div to surround each of the control. I just wonder if it this is possible...
Seems like making new user control is not a good way for me. I will just try to somehow map each original data and new data into a new User control, and write them into page.
I'm having problems with trying to get a string into a onclick event on an input button. Ill paste my code and explain more...
[Code]....
But i cant do that as the code is in an aspx page, not an aspx.cs page. I tried doing it this way...
[Code]....
But for some reason, when i try it that way, the page refreshes after the button is clicked and it messes up the layout of my page.
I'm getting "the input string was not in the specified format" on the last line of code below. The grid is based on a SqlDataSource that has a stored procedure pulling an integer for column 0.

theUserID = Int32.Parse(gvUserPermissions.Rows[gvUserPermissions.SelectedIndex].Cells[0].Text);

and this is my form design
I have got a function as below to check user whether input text is a legal words or not , but this function would trim or replace the bad words from input string.
Therefore i just want to match input string in this method (don't want to trim or replace). If it matched with any of these then should throw a message "Special characters not allowed"
Function remove_bad_words(ByVal stringword As String) As String
stringword = stringword.ToUpper
Dim newChars As String
Dim badstuff() As String = {
