Have you tried session variables ?? ex: on the datagrid page ..... Session["myValue"] = CellValue;
and then on the main page ..... TextBox1.Text = Session["myValue"].ToString();
Hope this helps.

Hi,
I have a new requirement to create a service so that my service would query the table every 5 0r 10 minutes to fetch the data from database and i have to pass the value to a particular port.

Hello,
This smells like polling. Do you really need to poll for data? What kind of value do you need to pass? Is this some kind of selection criterium or is this the amount of data that you need or what?
If you want to do database intensive tasks, you can try replicating the database and do all the intensive stuff on a dedicated server.

Problem Scenario:
We have a database with information.
We have some ASP.NET web applications that request information from this database.
We do not want to give these applications direct access to the database.
Solution:
So, we planned on creating an API layer with some c# objects (ADO.NET objects) that access the database and instantiates some objects with the information stored in their properties.
The applications will then be able to access the information from these C# objects, instead of directly connecting to the database.
We have to make sure that these objects are alive even if the web application is stopped.
To make a long story short, we basically want to create some stand-alone application (may be a windows service in C#) that exposes an API for the web applications. This stand-alone application has objects that act as caches by maintaining the up-to-date information. Whenever the server is on low load, it updates the database with the latest information it has. All applications should be able to access objects of this stand-alone application to get the information. This stand-alone application should live for ever, ideally until the machine on which it runs is shutdown.
Question:
Which type of project in Visual Studio should I create to develop such c# objects? Will Windows service be a solution? if so, how can I access the objects created by it?
Any help is greatly appreciated.

It's called Remoting. MSDN has many samples on this scenario

do you mean .NET Remoting? Does it use TCP?

This one[^] is good, but it doesn't cover Argentina either (it works for Brazil, if you ever need it). I always have the same problem with Mexico  .

Is it possible with GDI+ to just crop an image withou creating a new one?
I'm working with, say, 5 Mpix photos, so It can be superfluous, to create a cropped 4 Mpix bitmap and then drawing the first one to this.
I believe there is something similar to array reallocation applied to images...

Hi,
I have a normal windows form with a bunch of tabpages on it. But at the beginning, I want to do a little DirectX intro (which I've already created) in a class that I've been running separately. Now I'm not sure how to put them together without having to close the intro form and then open the main form. Is there any possible way to, say, create a surface on the main form that will run the directx stuff? I can't find any examples on this. Or any other thoughts?
Thanks!

I did it in C++ with a static (label) control. If something like that is what you're looking for, check out my 'Modeler' article here on CP.

Hi,
I am working on windows .NET application.
Here I have few comboboxes which i bind with my datatable.
Now I wanted the first item to be blank item so After I queried my datatable from database, I add blank row at the top of my datatable and then bind my datatable to the combobox.
Following is the code to bind the combobox with first item as blank:
dsDataSet.Clear();<br />
theAdapter.Fill(dsDataSet, "Table");<br />
tblTable = dsDataSet.Tables("Table");<br />
myRow = tblTable.NewRow;<br />
<br />
myRow("DisplayField") = "";<br />
<br />
myRow("KeyField") = 0;
<br />
tblTable.Rows.InsertAt(myRow, 0);<br />
objCombo.DataSource = null;<br />
objCombo.Items.Clear();<br />
objCombo.DataSource = tblTable;<br />
objCombo.DisplayMember = "DisplayField";<br />
objCombo.ValueMember = "KeyField";
Now Problem is that after I bind the combobox, If i do following
cbo.selectedvalue= <somevalue>
Here my <somevalue> is the value of the first actual item after the blank.
it is throwing an exception.
------------
In Method: Void set_SelectedIndex(Int32)
Specified argument was out of the range of valid values.
Parameter name: '-2147483648' is not a valid value for 'index'.
-----------
Any idea why is this happening?
here using selected value i am selecting the first item after the blank item in combobox.
Thanks
