View 1 RepliesI'm writing a web service that needs to query an Access 2003 database (.mdb). I've found the following code in doing some research on OLEDB connections and queries:
[Code]....
Errors are as follows:
Error 3 A field initializer cannot reference the non-static field, method, or property 'CompleteRentalls.completedb.sqlString'
Error 5 'CompleteRentalls.completedb.da' is a 'field' but is used like a 'type'
Can anyone help me rectify the above code such that the query results are returned to my datatable?
$('#dFinalReport').html(_todayOrderLstHtml);
$('#dFinalReport').dataTable(
{ "sDom": 'l<"floatR pLeft10"T><"floatR"f>rtip',
"aaSorting": [[3, "asc"]], "iDisplayLength": 20
});
How to use datatable in javascript?
i declared div element in html and called datatable using div id(dFinalReport).i got a error message

In 'Page_Load' event of my Masterpage I connect to a database and select a number of rows which I then store in a DataTable.
Now how can I access this DataTable from other pages? not only in codebehind in the Masterpage. I would like to use this DataTable as datasource in various usercontrols on different pages and I dont want to make the trip to the database again since I already have the rows stored in the DataTable in the Masterpage.
How do I refer to row index. I need to compare the data in the row before the active row in a foreach loop.
foreach (DataRow row in dtGCats.Rows)
{
tempCG_ID = Convert.ToInt16(row["CG_ID"]);
prevCG_ID = Convert.ToInt16( need row -1, row before above current row)
hi,i am creating form of purchase order . so i am using a datatable to get data from textbox, dropdownlist and then i want to display that data in gridview and after that do store that data to table in database . but due to some reason , its not working
I have a text file coming from another system that is in fixed format with header and details information regarding a request of material, looks like:
HDR 1000 HeaderDescription
DTL ProductId Productdescription qty ...........
DTL ProductId Productdescription qty ...........
DTL ProductId Productdescription qty ...........
I can read the file using streamreader on a "continous way" inside a do while loop, and parse it to obtain th different fileds required.i want to read the file, identify header line and fill a datatable, then identify details lines and fill another datatable to be able to insert both tables on the same transaction scope, if something fails rollback the insert.Im using a access 2003 database as backend and custom DAL and Business objects.
I have a datatable that I need to convert into a javascript array. This will allow me to do client-side validations on my webpage.
My datatable has 6 columns. X rows depending of the query results.
I was looking to use Me.ClientScript.RegisterArrayDeclaration but I just can't find how to build my 2-dimentional array to feed to this declaration.
On google I found some exemple for a 1-dimensional array, but nothing for 2-dimentional and I am not good enough in Jscript to figure it out myself.
i'm trying to sort a datatable using the typical select method*. The problem comes because the field is string defined but it's containing integer values.
With sql the problem will be solved just using something like:
select * from table order by to_number(field);
but of course it's not working properly with the method commented above (select method).

View 3 Repliesgetting a particular datatable values from the server to the client using javascript.
Ex.In my class which is Countries.aspx.cs I have this somewhere on my code say on the page load.
DataTable dtbCountries = Repository.GetAllCountries;
my dtbCountries now contains this record
ID Country
1 HongKong
2 Japan
3 Korea
In my webform I want to get the values of my dtbCountries using javascript
<script type="text/javascript">
// my code here to get the dtbCountries values
</script>
What should I do? Or what's the best thing to do to expose my dtbCountries in the client.
I have a simple web method written in the code-behind (not a separate asmx) of a test aspx page.
All it does is return a DataTable(or DataSet) both are failing, gives a blank 500 error saying "There was an error processing the request"
If I switch the return variable type to String, it works fine
I think my issue has to do with the version of the System.Web.Extensions, is that the assembly that actually contains the JSON communication implementation?
I've read all kinds of tutorials about how it should be possible to return the DataTable to javascript and then read the properties with javascript syntax.
For some reason it isn't working for me.
My web extensions is imported through my web.config with the following version
<add
assembly="System.Web.Extensions,
Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

View 2 RepliesI've written a Generic Handler so I can access my server's COM port through javascript. I'm doing this, because I'm writing a Web Interface to an ESP-88 from BOSE, for internal use. The code must be configurable, and I added routines for both TCP/IP support and RS232. In a desktop app, the code runs fine, but in an ASP.net 4.0 App, the code crashes with the error "Access to the port 'COM2' is denied.". TCP/IP connections work, but serial is also required for us.
