That in the long run, will be a bad application design. It's far far maintainable and trustworthy if you post each transaction to the database. You can always rollback transactions if they were not completed or cancelled.
As for your requirements, you can save the total available quantity in a global static variable and subtract each user's quantity from it.

Hi,
I have an application that generates .html and .mht files.Page generation is working good, but Some times there is a situation when contents in .html or .mht files goes out of A4(standard size for printing) size.So when I take a print of this page whole contents don't come.Some contents are cut down.But I want to print out the page with whole contents.What can I do?

There's nothing much you can do except resize the page dynamically to fit into an A4 or have a "Printer Friendly" page link separately.

The following version related Exception occurs from code
(FormsAuthentication.GetRedirectUrl(username, false).ToUpper().Contains("DEFAULT.ASPX") (or)
FormsAuthentication.RedirectFromLoginPage(username, false);
EXCEPTION:

Hi,
As I know that any thing you change through the Javascript, is not saved in the view state. Hence you can get it in the postback.
Yoy can get only selected value through request.form(name of the list control).
If you require all the inserted item you need to do it logically.

Hi,
when the admin login, iam displaying the list of users for the admin to view. when the admin select the details of a user there iam displaying the user details and also a button (say, Log into Resource Center as this user) in a seperate page. Here i have to pass the username and password of the user to a new url in a new window.How can we do this.
My code
StringBuilder strntrc = new StringBuilder();
strntrc.Append(""+Environment.NewLine);
strntrc.Append("" + Environment.NewLine);
strntrc.Append("" + Environment.NewLine);
strntrc.Append("" + Environment.NewLine);
strntrc.Append("");
This code is giving me error while execution:
Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
I googled about this error but couldn't find the relevant source.
Please suggest me how can i resolve this.
Thanks

Haritha,
remove the code from if(!IsPostBack)(means add the code in directly in page_load event) & Test it.
now event will works fine without any error.

Hi Sandeep,
Thanks for the reply. Yes I am read mails from outlook but if any of the undelivery mail is there then it throws and exceptions and stops reading mails after that.
Please help me if u know how to handle this...
|

|
|
|
You can't actually fetch mail from the outbox while outlook is in the process of sending the mails. It'll be locked.

Thanks for the reply but my requirment is different. When a user click on fetch mail button (which is located on ASP.NET Application ie my Project) it should read all the mails one by one and so I store the email ID's of the undelivery ID into database.
I have a code where it reads mails from outlook but if any mail is undelivery then it just stops reading.
Please help me with this...

Using the data formatting expression does not cause the problem like this. I think it is related with your Database code.
Please check it or give the details about the method you are using to save the data into database.

See in datadrid i am getting values in that column like...,
Col1
510.09
234.78
12344.76
Values for with in datagrid so i try to store those value in this format(my add button click event)
For Each MainGRD As DataGridItem In Me.dgrdsub.Items
sqlconn.Open()
Dim strInsertproc As String
Dim GTotal As Decimal = Val(MainGRD.Cells(3).Text)
Dim BonusAmt As Decimal = Val(MainGRD.Cells(5).Text)
Try
strInsertproc = "BonusAdd'" & GTotal & "','" & BonusAmt & "'"
sqlCmd = New SqlCommand(strInsertproc, sqlconn)
sqlCmd.ExecuteNonQuery()
lblMessage.Text = "Record Inserted............"
Catch ex As Exception
If Mid(ex.Message, 1, 9) = "Violation" Then
lblMessage.Text = "Already exist in the DataBase......"
Else
lblMessage.Text = Mid(ex.Message, 1, 75) ' Show friendly error message.
End If
End Try
sqlconn.Close()
In that col1 if i give {0:N} then the values store in my table like:
5
2
1
If i remove the data formatting expression {0:N} then the values store in my table like:
510.09010
234.787778
12344.766576

Hi,
have you checked what is being stored in the variables "GTotal" and "BonusAmt" during the program execution.

ya i checked if i give data formatting expression{0:N} Then first value..,first number only i am getting...,
If i remove that format exp then i am getting correct value...,
Magi

Hi,
Format does not cause error like this. Please check the variables' value after statement like
Dim GTotal As Decimal = Val(MainGRD.Cells(3).Text)
Dim BonusAmt As Decimal = Val(MainGRD.Cells(5).Text)
and check your stored procedure "BonusAdd" and its parameter type and width.
