Hi
Please find which Cause the problem
Response.Redirect("PrintQuote.aspx?Print=" + grdVwAgentQuote.SelectedRow.Cells[7].Text+" & Quote="+TextBox1.Text);
dataPrinting = adapterprinting.GetData(int.Parse(Request.QueryString["Print"].ToString()), int.Parse(Request.QueryString["Quote"].ToString()));
When i just call one querystring. Its Working Fine. But if i call both the QueryString Then the Null Exception is showing on the Print. But if i pass only Print as queryString its working Fine.Please advice to solve the issue.

When you try to read the value using the name "Quote", you will not find it as the name is " Quote".
Remove the extra spaces around &.
Also, you should use Server.UrlEncode to encode the values before you put them in the query string.

Can you send some Sample Code for Server.URLEncode. Because it gives error to me

Example:
Response.Redirect("Page.aspx?something=" + Server.UrlEncode(someValue) + "&other=" + Server.UrlEncode(otherValue));

Thanks for your comment. And if I've offended any woman by what I said earlier, I'm sorry cos I didn't mean it in any way. So this goes for the women.

Does any one know how to get a remote web server to transfer its Certificate (X509Certifcate) to the local machine using Sockets? I need the public key from a given web server.

I know.
I have given up hope. I think I am going to the route of setting up an SSLSocket just to get the certificate information from the web server. This seems like a waste of resources to me.

What are you talking about? How else do you expect to get it, magic? Maybe you need a career change, you could call youself "The Great Cardi".

led mike,
The public key exchange for SSL is done before the SSL connection is established. I belive this is how the protocal works (Maybe I'm wrong). That is the only portion of the SSL protocal that I am looking to implement. I not really interested in secure communication or ecrypted sockets. I just need the server to transfer me its SSL cert.

Mike,
I am aware of how the SSL protocal works. What I am looking for is if someone on has implemented just the Handsake or X509 Certificate exhange portion of the SSL protocal. As the title of this topic suggets.

Im trying to be able to click a button and have qtys added and deducted from my db. I have a update query that works fine when I execute it. The problem Im having is using the query in my click event. Heres the code:
<< private void btn500pballs_Click(object sender, EventArgs e)
{
this.inventoryTableAdapter.UpdateQuery500(this.paintballDataSet.Inventory);
ListViewItem item1 = new ListViewItem("Paintballs 500ct");
item1.SubItems.Add("$12.00");
listViewmain.Items.AddRange(new ListViewItem[] { item1 });
}
>>
I keep getting an error
No overload for method 'UpdateQuery500' takes '1' arguments.
Any help, please?

UpdateQuery500 is some function that you defined? The error No overload for method 'UpdateQuery500' takes '1' arguments sounds like the function call
this.inventoryTableAdapter.UpdateQuery500(this.paintballDataSet.Inventory);
isn't calling UpdateQuery500 with the correct number of parameters.
|
|
|
|
|
Yeah the Updatequery500 is an update statement that increments qty sold by 1 and decrements qty on hand by 1 in a specific row. What would dictate the number of parameters?
Jon Henry

|

The number of parameters is dictated by the functions' definition. You need to find where the function is defined and check there to see what else you need to pass into it besides whatever this.paintballDataSet.Inventory is.
Ex.
private void btn500pballs_Click(object sender, EventArgs e)
{
}
requires you pass in an object and EventArgs as parameters when calling it (although it looks like an event handler, so you shouldn't be calling it directly).
As others have said this is pretty basic. If you're really that new to C#/programming in general then you might want to check out some primer articles here[^] before you dive into databases and other more advanced stuff.

What's the problem? Do you understand what that error message means?

Actually I dont, Im a novice.
Could you explain the 'arguments' thing?

I think you should learn basics of programming first and then try to update database. IMHO
