Feb 18, 2011
i have created a program which saves login and logout time for a project.there may be more 2 login for a same project.i need to store the total working time for a particular project from all login/logout time.then for the same date there may be more than one entry.Ex:
Project name: Test
User name:
Login time:
Logout time:
Total Time: logout-login
Date:date of login
this is a format of table in database..more than one user will work for the project.there may more than one entry for a day by different users for same project.i need to put a chart for this table with date in x axis and total working time for that date in y-axis.How to calculate the values for this constraints

I'm creating a form that sends a data set into an XY scatter plot. I have a report and reportviewer set up correctly, however my chart will not adjust the vertical position of the data points! They're tied to the table below (and have data labels), however when they get plotted they're always right on the x-axis.
I am saving users information in Sql Server 2005 Database. The problems are:1. If a user selects 1/Jan/1990 then in the Age column of the database automatically 23 should be saved i.e users age, how do I calculate the age and use it in the query? 2. The format of DateofBirth column is incorrect it should be 1/Jan/1990 inspite of2013-01-01 00:00:00.000. The data type is Datetime
I have a databound gridview in which i have added a template field to display a calcultion. I have created a rowdatabound event in which I want to perform a calculation, but don't know how. The calculation is as follows:
First, it should take the sum of all the payments made by a given customer. It then should divide this value by a daily membership rate, returning a days paid variable. Finally, it should add that variable to the customer since field and calculate the date that the customer is paid through.
I tried with no succcess doing a search here on the forum for some answers or pointers. So here goes.
I would like to Calculate total time from a records in a table.
the Table we'll call it "Time Table" may have four rows IE.
Field1 Field2 IN 08:00:00 OUT 12:30:00 IN 13:00:00 OUT 17:00:00
I am trying to display these records in a Child gridview with a total. Is there any SQL that can total time like this? or any other way I can total this?
I have following codebehind in ASPx - VB.Net in my aspx project, i want sum a template column (txtAmount) to show another TXSum template (without any postback) any one give me a better soluation in javascript.
in my asp.net_vb web there is a text box (textbox1) in which a date is dispalyed from database (eg 21-Mar-2012) in another text box (textbox2) i want to display
if the date is less than 30 Jun then the textbox2 should display 1 Jul+the year of textbox1
if the textbox1 date is greater than 30 Jun the text box2 should display 1 Dec + the year of textbox1
I had just started with Visual Studio 2008 + VB.net. I've now designed my tables, and basic gridview functions properly.Now I'm faced with the problem of having to calculate a value based on 2 - 3 columns/data in the gridview, display the result in an existing column in the same gridview, and saving the calculated value in the datasource.I had initially created the "Total" column as a textbox displaying a manually calculated amount that is saved in the datasource. Now, I want to change the field to auto-calculate based on 2 other columns.
In my webpage i am trying to create a order by gridview here item selected by user from dropdown and on selction of dropdown price display in next to item dropdown label price.now user insert quantity from next grid textbox and next is label amount shold disply calculate amount on price and quantity.i also want to use javascript for this prob.what i did that item and price displaying and user make input from textbox now want to calculation but how textbox recieve input and amount label dispaly calculate amount.
I have a rather large formview that asks for a variety of input values (physical totals vs pos report totals). I have created vb code to calculate the differences and subtotals of various types prior to inserting the data so people can check for entry errors.
Its a closing reconciliation form. Here's the problem: If they forget to enter 0 in a field that doesn't have any totals, a big ugly error message displays. I would like to avoid this. I can tell them until I am blue in the face to remember to enter 0 and not leave any blank fields, but realistically its going to happen and I need to handle it in the programming.
I have been struggling to either default the values to zero to start with, replace a null textbox with 0 before the calculate runs...but I can't get anything to really work. What is the best way to handle this?
Here is the aspx page:
[Code]....
And the code behind page with working "Calculate" as long as fields are not left blank (I took out all the test code that made it not work at all)
[Code]....
Finally, the error message I am getting is the following:
[Code]....
I can't seem to find the right combination of programming to account for the "" string to be 0 so that it will add or subtract values in my calculate. I have my sql table setup with default values of 0 so if a field is left blank it will be entered into the database as 0 and not null. It is really just for my inserting of a reconciliation and the running of Calculate Totals to double check their work prior to inserting into the database.
