my asp.net application using crystal reports...the application execute fine and well on my local machine...
my problem was, when i deploy my asp.net application in the server it works fine
but there the exporting of report does not work it gives me a blank page....
my findings was, the why export does not function is because the server dont have
a crystal report application.. i just used my reference embeded in my asp.net application... is my finding correct? or really there is something i miss to code in my application...
pls i need your help very badly... can you give me a link or a sample code?... that will work to a server that does not have crystal software installed.

From what I know  there is no way to calculate infinite precision with out loosing any decimal
You may want to take a look at these data types
The nearest datatypes you can use are float, double and decimal.

Use Double Datatype.
Double variables are stored as signed IEEE 64-bit (8-byte) double-precision floating-point numbers ranging in value from -1.79769313486231570E+308 through -4.94065645841246544E-324 for negative values and from 4.94065645841246544E-324 through 1.79769313486231570E+308 for positive values.

You can not have infinite precision, as you don't have an infinite amount of memory availabe.
The Decimal data type is the built-in type that gives you the highest precision. If that is not enough, you need to create your own data type or find someone who has.

Hi, I'm trying to read a blob from my database table but ran into a little problem that I can't seem to solve. The following code is used in the page load and the button_click section of the code behind. I got the exception
"Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" when I tried to view it in the browser.
<br />
Dim i As Integer<br />
For i = 0 To ListBox2.Items.Count - 1<br />
If ListBox2.Items(i).Selected Then<br />
Dim myCon As New OdbcConnection<br />
<br />
myCon = New OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=myServer;Database=myDB;User=myUserassword=myPass;Option=3;")<br />
Dim cmd As New OdbcCommand("SELECT * FROM myTable where Professions = '"& ListBox2.Items(i).Text &"' ")<br />
<br />
myCon.Open()<br />
<br />
cmd.Connection = myCon<br />
<br />
Dim ds As New DataSet<br />
<br />
Dim ad As New OdbcDataAdapter(cmd)<br />
<br />
ad.Fill(ds)<br />
<br />
Me.ListBox2.DataSource = ds<br />
<br />
Me.ListBox2.DataTextField = "Professions"<br />
<br />
Me.ListBox2.DataBind()<br />
End If<br />
Next<br />
I searched online for possible causes of this error but, none of the causes that I found has anything to do with my situation. Please take a look to see what I might of missed, thank you in advance for your help.

Where are you making this call in code? Is this Single or Multi select?
Have a look at MSDN[^], and the ListBox class, specifically the OnSelectedIndexChanged event and the SelectedIndex, SelectedItem and SelectedValue properties, ListBox members[^].

That mistake was already spotted when I last post a message a day ago but I forgot to change it when I paste the code in the message box. Unfortunately thats not the problem but thanks for your help. This call is made in the page load and in the button1_click sections of the code behind. The listbox is in multi-select mode.

I am trying to read blobs from a field in a database table. The blobs hold resumes and each resume can have one or many corresponding professions in the Professions field. I am trying to enable users to look up resumes forcertain professions by choosing one or many professions in the listbox. The Select statement selects my table where the text of the listitem chosen by the users match the profession in the Professions field.

on which event u call this code?

Imran Khan Pathan is right... I didn't see it the first time but you are doing something like these
You have a "for" that walks through the listBox2 elements and sees which is selected...then you make a query in the database (inside that "for") and you bind the result of the query with the same listBox2...these alters the containt of the listBox2 and the for is not working anymore (ListBox2.Items.Count is not the same after you have done the binding in the "for" statement and also the ListBox2.Items are changed)
Just call me Valy...

You are changing the items of the list box while you are looping through the items.

I've used the for loop to determine the list item selected by the user. Then I used the select statement to select the profession that is equal to the text of the list item that was selected. If I change the contents of listbox2 during each iteration of the loop when I bind the data to listbox2, then does that mean I can't use the for loop like I did? Should I bind the data out side of the for loop? I'm going to try and change the sequence of my code, but please give me some suggestions on how to remedy this code.

Take datalist in div tag and apply style="display:none;"
Javascript function
function visibility(divId)
{
if(document.GetElementById('divId').style.display=="none")
document.GetElementById('divId').style.display="block"
else
document.GetElementById('divId').style.display="none"
}
