I have a simple problem that I need to know either the best solution for or a list of the options.

I need to export data from a database into a an excel spreadsheet. I will more than likely use a stored procedure to create the result set and then use a datareader to bind to whatever object you suggest.

The spreadsheet needs to be emailed to a recipitent so I would prefer it as a memory stream object so I have the flexibility to do this.

Thanks

Hmm looks like a lot more code than I was expecting. Also doesn't look ideal for my situation eg opening instances of excel etc.

Someone else suggested exporting to XML or CSV and then importing to Excel?? Any ideas on this?

In either case, if you want an Excel object in memory, to be attachable in Email, you need to instantiate using interop.

You have to write javascript that captures the keypress, works out what it is, and calls teh script to submit with that button.

<br />
     TextBoxThatIsFocuseWhenEnterPressed.Attributes.Add("onKeyPress", "doClick('" + ButtonToTriggerOnEnterPress.ClientID + "',event)")

Put that in the page load event.

And then this in the page

// Default button code<br />
function doClick(buttonName,e)<br />
    {<br />
//the purpose of this function is to allow the enter key to <br />
//point to the correct button to click.<br />
        var key;<br />
        <br />
        if(window.event)<br />
            key = window.event.keyCode;     //IE<br />
        else<br />
           key = e.which;     //firefox<br />
    <br />
        if (key == 13)<br />
        {<br />
            //Get the button the user wants to have clicked<br />
            var btn = document.getElementById(buttonName);<br />
            if (btn != null)<br />
            { //If we find the button click it<br />
                btn.click();<br />
                if(window.event) event.keyCode = 0;<br />
                <br />
            }<br />
        }<br />
   }

If it were me I would put the javascript code in a sperate js file and then reference it into the page. Why? Chances are you will use this elsewhere once youv'e got the function so it saves posting the code into each page.

If you didn't know you do it like this

<br />
    <script type="text/javascript" src="JavaScript/DefaultButtonScript.js"></script>

Another option, you can define a default button for your page (other containers support this as well) which creates the needed JS for you.

The end result (rendered JS) would look like this:
onkeypress="javascript:return WebForm_FireDefaultButton(event, 'SomeButton')"

It's pretty much what was offered, just an easier implemenatation if it works for your particular situation.

Your aspx file cannot do a screen capture on the client. It can, on the server. I'm guessing that's not what you want tho ?

Your aspx does not run on the client at all, the client just gets html, javascript and css.

You'll have to build the list by hand, there's no function for returning a sequence of days, let alone weekdays only. The DateTime class can format your date as a string, and should do everything else you need as well.

Hi,
Try with

Date.ToLongDateString()
Date.AddDays(1)

To succeed, we must first believe that we can.

textbox problem

Dear all,
Here i had a problem that when i click a textbox,it has to give the sum of two other textboxes.
I have two ideas for this,
1,using javascript

function getBal(obj)
{
var v1 = document.getElementById('txtbox1').value
var v2 = document.getElementById('txtbox2').value
if ( !isNaN(v1) && !isNaN(v2) && !isEmpty(v1) && !isEmpty(v2) )
{
var baln = parseInt(v1) + parseInt(v2)
obj.value = baln
}
else
{
alert("Please fill the fields with valid numbers")
}
}
function isEmpty(txt)
{
if (txt == "")
{
return true
}
else
{
return false
}}

2,make textbox2 property autopostback=true and on textchanged event ,i will add both the values and put in the third textbox.

Private Sub Txtbox3_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TxtExpectedYield.TextChanged
Txtbox3.Text = Integer.Parse(Txtbox1.Text) + Integer.Parse(Txtbox2.Text)
End Sub

Apart from these two can i do in any other way??
only by clicking textbox3,it shd give the sum.if txt1 or txt2 are blanks then it shd assign 0 and give the sum.
How to do this???
Thanks in advance

No, you've got both bases covered, do it on the client, or do it on the server.

Except that you probably want a button to post back, not the text changed event.

I am using DTSearch and it's really nice. It has APIs and does a crawl of your site. I haven't aimed it directly at a database yet but I guess the functionality is there. Otherwise, I always create some kind of webpage that the DTSearch engine can crawl.

Hi All,

I am developing Rich Text Editor and I am have to save the text in DB, the problem I am facing is with bullet list or ordered list.

Actually when newline comes it replaces the newline with some kind of box and in DB it saves all the contents which is before that box.

I need to save the whole text with newline and retrive the same text with newline.

Please help me...

Thanks in advance

You need to escape the unprintable character with a slash:

newline is \n
return is \r

Not sure if this will help. Can you give more information if it doesn't?
