Sorry, as in wrapper methods like:

SqlConnection conn;

public SqlConnection GetConnection()
{
   conn = new SqlConnection(connString);
   conn.open();

   return conn;
}
public void CloseConnection()
{
     conn.close();
}

I'm guessing not.

The client might be waiting... If the code is as much of a mess as you say it is, then there might not be a quick stopgap fix for this problem. Write a scheduled script to restart the DB every so often... Wink | ;)

Well, I was wrong. If you use "In-process" mode of session state it does in fact keep your object in memory.

http://www.informit.com/articles/article.aspx?p=29457&seqNum=4[^]

If you don't use in-process, it stores it as xml.

But regardless, it was a poor choice to code it that way and you should fix it.

I didn't get any requirements for the signature

Hi
I have a Panel, which contains 'customer information', ie date of order etc. Input is aided by extenders, checkBox, date validation etc. All out of the box microsoft Ajax extenders. Works a treat. I have a close button - which when clicked, fires some javascript to remove the panel from the DOM, and then calls a webservice. The user doesn't care about the webservice, they're just pleased the panel has gone (quickly).

But....removing the panel does not remove the Script that the Ajax library injected into the page. So if they load up the Panel for the same customer, javascript errors are abound saying you can't add the same control twice - for each extender I try and add.

So...how can I, via javascript, remove the script that was added by the extender, or is there a safe way to remove the whole extender, including script, clientside. I really don't want a postback here.

Cheers

how to retrive data from dataset

hello frndz.

i am using a dataset. and i want to retrivw value from that.
for that i am using

Textbox1.Text = dsAppData.Tables[0].Columns[0].ToString();

Textbox2..Text = dsAppData.Tables[0].Columns[1].ToString();
where "dsAppData" is the name of my dataset

... well through this i am getting the value.
but here the problem is.
if there are 20values neeed to be retrived from dataset.
the each time when i retrive the value i must use dataset.

so here i think it reduces the perfermance of the application as it hits
the database each time i populate the data from it.

so is ther any other way to retrive data from dataset only using once
means for the first time when we use the dataset we will keep all the requiered value
from it.
plz i need ur suggestion

DataSet is logical database. you can use it in connection less envirment. so it does not have any direct connection with database.
if you go through the details of ADO.NET , you will see there is connection oriented and connection less mode. and Dataset comes under the connection less mode.

So i think there should not be any performance issue if you use this .

Hi,
Guys anyone having idea about the Tools/ Third party Tools/ Mechanism to utilise already existing Visual Basic Forms into Asp.net Applicaiton.

Here I am explaining Completly:

Using RCW/Com Interop i am able to use the Class and methods. But if a class library contains Windows Forms as well, how can i utilise them.

Any suggestion regarding this will be a great help !

Thanks in Advance.

You would be much better (and it would probably be a lot easier), to simply re-write your forms in asp.net.

If your code separation has been done well, this shouldn't be a big problem.

Thanks for your suggestion !

That is the end solution ! Only Web Page creation is not a matter, Lots of events codes are associated with Win Form, so how to deals about that.

Problem with CascadingDropDown

19-Dec-07 1:41

That's unfortunate, it would be handier for you if all that code was abstracted out, but anyway. You will need to rewrite these, if only for the reason that winforms is stateful and asp.net is stateless - i imagine that a lot of your event code will not work because of this.

Hi All,

I am using CascadingDropDown on my web page and when I click on the save button I have to save all the data into database, which works fine.

But I want to set the values of CascadingDropDown to Select again.
Ex: I have 2 combo and when I say save then these combo's must be set to Select Country and other one to Select State.

Please help me with this.

Thanks in advance....

except that will fail with Null reference exception as you have not instantiated objLi[0] or objLi[1]

HtmlGenericControl[] objLi = new HtmlGenericControl[5];<br />
objLi[0] = new HtmlGenericControl();<br />
objLi[0].InnerHtml = "First element";<br />
objLi[1] = new HtmlGenericControl();<br />
objLi[1].InnerHtml = "Second Element";

Hi,

If the Textbox value is empty then, when i click "Ok" button an alert should display as "Please Enter the value for textbox" and simultaneously i have to display an "*"(Asteristic) only if the textbox is empty. Otherwise don't display.

Please help me..

if(document.getElementById('txtbox').value=="")
{
alert('Enter text value');
return false;
}
-------
<asp:textbox id="txtTickInfo" runat="server"></asp:textbox>

<asp:label id="Asteristic" runat="server" forecolor="Red" text="*" visible="false"></asp:label>

So what's the problem here ? Why don't you use validation control ?

yes here i used validation as below you see

if(document.getElementById('txtvalue').value=="")
{
alert('Entertext value');
document.getElementById('Asteristic').style.display="inline";

return false;
}

but it says "Object required".
How can i display the "*"(label control) only if the textbox is null?

I guess your textbox name is txtTickInfo. Check that

Your textbox id is txtTickInfo, not txtbox.
