I'm going to just hazard a guess here and say that your input string is not the correct length for a base 64 encrypted string. Just a guess...
You might want to look at where that string is coming from...
|
|
|
|
|
You haven't provided enough information for anyone to give you a solution.
The error message says that the string is not a valid base64 string. Therefore the problem is not with the code that you are showing, but in the code where the string is created.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
I want to develop a page in asp.net in which when user type any word the list of corresponding words or list of words starting with that char should display in the drop down and user must able to select that.
for example Visual Studio when we type any word and press ctrl+space bar the list of words appears. i want to do the same.

you can do this by using ajax in you application. Whenever you enter a key it will fired and show the related record by calling the ajax function(ues like in database stored procedure).
|
|
|
|
|
Create a textbox, and tie it to a database. On the OnTextChanged event, load the values from the DB using the rowfilter.

Hi
I have the following code which is running on the page load:
ArrayList originalTrue = new ArrayList();
ArrayList originalFalse = new ArrayList();
for (int x = 0; x < GridView4.Rows.Count; x++)
{
GridViewRow row = GridView4.Rows[x];
bool isCheckedIgnore = ((CheckBox)row.FindControl("chkIgnore")).Checked;
string strID = GridView4.DataKeys[x].Values[0].ToString();
if (strID != null)
{
if (isCheckedIgnore == true)
{
originalTrue.Add(strID.ToString());
}
else
{
originalFalse.Add(strID.ToString());
}
}
}
ViewState["originalTrue"] = originalTrue;
ViewState["originalFalse"] = originalFalse;
The problem is when I go to the second page of the gridview it doesnt run.How can I get the code to run on the second page of the gridview?
thanks

If you have the code in a
if (!IsPostBack)
it will only run when the page loads and not each time there is a post back. Is this the case here?
|
|
|
|
|
Well it currently sits in a ispostback = false.
The problem is that the viewstate seems to keep the state of the page over the postback which I dont want to do.
I need to store the arraylist in some sort of session so that I can check it when the page of the gridview changes. This is because the values it is storing in the viewstate for the row id is then being used when the gridview page changes which obviously is no good.
How can I store the arraylist in a session so that it works over multiple pages in the gridview?
thanks

{ chkbox=(CheckBox)item.FindControl("chkbox");
txtbox=(TextBox)item.FindControl("txtbox");

}
}
in this coding i am getting probs...in the for loop.....
initially i got error like this...
Error:'System.Web.UI.WebControls.GridView' does not contain a definition for 'items'
so ... i tried with
foreach(DataGridItem item in DGSample.rows )
even i am getting error like
Unable to cast object of type 'System.Web.UI.WebControls.GridViewRow' to type 'System.Web.UI.WebControls.DataGridItem'.
can u anyone help me to solve this prob???

The DataGridItem was used with the older DataGrid control.
You need to use the following:
foreach (GridViewRow item in DGSample.Rows)
{
}

Is the picture in the correct location on the server? Check the path you are generating.

This return a local path as c:\...
What you need is a web url like http://...
Use this:
ImageUrl='<%# Eval("url", "~/Attachment/picture/{0}")%>'
or
ImageUrl='< DataBinder.Eval(Container.DataItem, "url", "~/Attachment/picture/{0}"))%>'

Either way, how do YOU think it should be done - after all, you have asked similar questions in the past so you ought to have an idea by now.

I need to know the current system language ,
I found that code :
Bll.Language.Language.GetSystemLanguage(language);
but i don't know the namespace of Bll
thanks
jooooo

Hi
The Bll.Language.Language namespace is not part of the .NET framework.
The namespace you are interested in is: System.Globalization.Cultureinfo[^]. There are some good code examples further down that page.

Please anyone may help!
I am trying a program to send a attachment(only one attachment) to 3 mail recepiants . After sending the mail (a success one) I am finding that the attachment sent to each of the recepient is attached thrice(same file is attached to the mail) whereas I am attaching only a single file.
And more over I am getting the mail twice as if I clicked on the SEND button twice(infact I clicked only once).
Please help me . I give my code as below
![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) thanks in advance
protected void Button1_Click(object sender, EventArgs e)
{
string[] addresses = {"mailaddress1","mailaddress2","mailaddress3" };
SmtpClient smtpMail = new SmtpClient();
smtpMail.Host = "smtp.abc.com";
smtpMail.EnableSsl = true;
MailMessage mail = new MailMessage();
mail.From = new MailAddress("abc@abc.com");
string fileName =
Path.GetFullPath(FileUpload1.PostedFile.FileName);
for (int i = 0; i < addresses.Length; i++)
{
if (FileUpload1.PostedFile != "")
{
try
{
mail.Attachments.Add(new Attachment(fileName));
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
mail.To.Add(addresses[i]);
Response.Write(addresses[i] + " ");
mail.Subject = "HAI!!!!!!!";
mail.Body = "ATTACH TO ALL";
smtpMail.Credentials = new System.Net.NetworkCredential(username.Text, txtPassword.Text);

{
smtpMail.Send(mail);
Response.Write(" Mail Sent");
}

Console.WriteLine(ex.InnerException);
}
}
}//end of event click

Hi kvsreedhar
The attachment is add 3 time because it is inside the for (int i = 0; i < addresses.Length; i++) block.
If you remove the for loop it will be attached once.
|
|
|
|
|
thanks for your replay
but without using the loop how can i send to 3 persons with just one click?

You only need to create one MailMessage object, attach the attachment once and send it once.
The only part that needs to be in the for loop is
mail.To.Add(...<code> <br />
