Regarding Regular Expression

No, you cannot use non ASCII characters in a URL, and even some ASCII chars, like &, will get encoded. That's how URLs work.

Here's an interesting question. What if someone types it in the German format, but they are in the US ?

Can't you see where your regex is looking for a dot ? It's (\.\d). Are you just using regex you find on the web, without bothering to learn how they work ? Replace the . with a group so that you will match one character with either a dot or a comma.

File Upload Encryption

Hi all,

I would like to upload file to server with encryption. The requirement is that the file should either encrypted first before being uploaded or it can be encrypted later on after being uploaded.

On downloading the file the file should be in the decrypted form.

I am using ASP.NET 3.5 with C#

Any help/suggestion will be appreciated.

Happy Coding,
Vivek Rathore

It's probably going to be easier to encrypt the file after sending it (but really not very useful). Is the same host downloading the file? Unless the same host that is downloading the file, you'll need to send some sort of encryption key.

This site will likely have all that you need to get started: http://www.devhood.com/Tutorials/tutorial_details.aspx?tutorial_id=489

A secure and useful method would be to open a secure communication using a public/private key pair and then the server could send an encryption code for the client to encrypt the file. The client would then send the encrypted file to the server and there the server could decrypt the file since it knows the encryption code.
That way is going to be a lot more difficult, but more practical.

Hope that helps.

How to Access user entered values from runtime generated textboxes

Hi!!

All I am developing a site using ASP.Net I want to develop a site that generates textboxes,lables,tablecells at runtime ie is from database itself depending on the no of rows in the table in database. That is to get as many textboxes as there are rows in table. What I am doing right now is creating new text boxes in the code and then adding them to the cells and rows of the table control.All it is I am doing on PageLoad event. This all works fine.

The problem comes when I have to extract data from the form which is entered by user and insert into databse table onClick event of button. As it is in other function I am not able to access textboxes and its properties on that event function code. How do I get the properties of the controls generated in runtime and placed on the Table control?

while on click to get value code are as fallows

string Value = string.Empty;
Table tbl = (Table)Panel1.FindControl("table123");
for (int i = 0; i < NumberOfControl; i++)
{
TextBox txt = (TextBox)tbl.FindControl("DynamicTextBox" + i.ToString());
Value = Value + txt.Text + "";
}
Label1.Text = Value;

If you generate them after or during page load, they won't ever have viewstate. The best way to deal with this, is to store the text that's entered in a hidden control, perhaps as XML if you have many textboxes ?

Probably you are adding these dynamic control in another control like place holder or panel, in that case you must use search dynamic controls in that panel or place holder, like:

VB Code
-------
Me.Panel1.Controls.Add(txt1)
Me.Panel1.Controls.Add(txt2)

must be read like

Me.Panel1.FindControl(txt1) instead of Me.FindControl(txt1)

Hope this helps.

Hi, I write it as u mention. But it does not work.

xmlHttp.open("GET","ResponserFile.aspx?id=3&name=nam&cell=cell,true)

Can u correct it ? Pls..

you are using a comma before true, this is not correct. The correct string will be like:

xmlHttp.open("GET","ResponserFile.aspx?id=3&name=nam&cell=cell&var=true")

in the above syntax id, name, cell, var are variables that will be called by:

Request.Querystring("id") etc....

& is user to join two variable so be careful to use values.

Hi Karthick_gc,

Have you tried doing it like this:

xmlHttp.open("GET","ResponserFile.aspx?id=" + id + "&name=" + nam + "&cell=" + cel + "&bool=true");

I'm assuming that id, nam and cel are variables. Then to retrieve the data on the form you would use:

Request.QueryString["id"]
Request.QueryString["name"]
Request.QueryString["cell"]
Request.QueryString["bool"]

I hope this helps.
