Hi
How can I make a auto generated column read-only. Means when I click the edit button some column data should appear as it is. It should not change to edit mode. As we are making a column read-only in window app. Is it possible in web app?
Thanks & Regards

Hi all,
How can I create a short cut key any button in .net. Suppose I have a button named btClick and button text as "Click". In this I want to keep "C" as short cut key for this button click event. Can I do it in Windows and Web applications too?. If so please tell me how in both type of applications?. Thank you.

I don't think you can in web apps. In windows apps, you can certainly catch a keyboard event and call the button click if it's a 'c'. I am not sure if it's possible otherwise. In a menu, if you type &, as in &Click, that gives you a shortcut.

if you want to do it in web application,you must have a focus on something(e.g textbox) and then catch the keyboard code to press

Yeah, ok. Even then too, how. Please give me the details if possible please. Thank you.

This means, you can handle a key press in javascript, so long as you require the user to have focus on a specific control. Or, you can hook the code up for all controls, I guess.

Where are you clicking ? If you don't see a security tab in Explorer, chances are you have basic security turned on.

Well, do you have a web.config file there, or not ?

im using vb. To summarize, i have a textbox where user input quantity and a gridview to display the price. i also have a submit button to calculate the totalprice where totalprice = quantity * price.
meanwhile im using a label to store the value price.
<br />
Dim tmp As Double = e.Row.Cells(3).Text.Trim<br />
Label1.Text = "$" + (tmp).ToString("0.00")<br />
this is the submit coding
<br />
myCommand.CommandText = "INSERT INTO [Order] ([Quantity], [TotalPrice]) VALUES ('" & CStr(Me.txtQty.Text) & "',__________)"<br />
<br />
is ________ me.txtQty * Label.Text ?? i need to know what should be the correct way.<br />
<br />
<br />
<br />
thanks in advance. Much appreciated.

Plz try this
cdbl(me.txtQty.text) * cdbl(Label.Text )
or
cint(me.txtqty.text) * cint(Lable.Text)
Your access database column type should be integer, Float or Double....
Quantity,TotalPrice.
Better way.........
dim Total as integer = cint(me.txtqty.text) * cint(Lable.Text)
"Insert Into order (quantity,TotalPrice) Values (" & me.txtQty.Text & "," & cstr(Total) & ")"

thanks but there was an error
No value given for one or more required parameters.
Dim Total As Integer = CInt(Me.txtQty.Text) * CInt(Label1.Text)<br />
myCommand.CommandText = "INSERT INTO [Ord] ([Quantity], [TotalPrice]) VALUES ('" & CStr(0) & "','" & CStr(Total) & "')"
i change my databse for TotalPrice to number instead of currency.
thanks in advance. Much appreciated.

The error message means that you have one or more names in the query that doesn't match the database. Check the name of the table and the names of the fields.
If the fields are numeric, you should not use apostrophes around the values, as that makes them string values.
Why are you storing the total price in the database anyway? If you display the data later, don't you want to display both the price and the total price? You can always calculate the total price if you store the price and the quantity, but if you store the total price and quantity you have to re-create the price, which is a bit backwards.

in detail, i have two tables, 1 is products details and the other is order details.
so the totalprice n quantity are meant for the order details table.
so how should i solve the problem? both the field names are spelled correctly.
thanks in advance. Much appreciated.

I see. You might consider copying the price from the products table to the order table at the time of the order, so that the orders doesn't change if the product changes.

The database begs to differ... 
Debug the application and look at the query that you created, so that you see if it ended up the way that you expect.

thanks very much
this is abstract:
Project Title : TRADING PARTENERS COLLABORATION
ABSTRACT
The Trading Partners Collaboration application is a web-based application for primarily providing Services to Companies who hire Consultants from vendors/suppliers. The main aim of this application is to Reduce Administrative costs by automating the workflow (via Web) taking place between the people on the Company-side and the people on the vendor-side and the hired Consultants.
This Application is useful for preparing the timesheets, which are entered by the consultants. Time sheet consists of company and project details and for each task like coding, design, testing, and documentation etc, the number of hours they worked throughout the week.Consultant having the permission to enter the time sheet. Also can check different types of reports based on project or client wise. These entered Time sheets can be approved or rejected by the manager (approver).this approving the time sheets is done by manager at the end of week by selecting option called week ending dates. At the manager’s login there are reports based on different search criteria. To maintain the details of users, projects, consultants, permission to login users and define the new roles can be done at administrative tasks. This application is maintaining three types of logins consultant, manager and administrator. Consultant can act as timesheet entry or expense sheet entry. Manager role is to approve the time sheet or expense sheet. And admin maintain all the details of consultants, managers, projects and roles. This reduces administrative costs for the company side.

I think the idea is that you write it.
