If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?
Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?
STDNo nvarchar(6) //student number primary CID nvarchar(7) //course ID primary DNo int //Department Number primary H1 int allow null // Home work 1 H2 int allow null H3 int allow null H4 int allow null H5 int allow null Q1 int allow null //Quize 1 Q2 int allow null Q3 int allow null Q4 int allow null Q5 int allow null HE1 int allow null HE2 int allow null FExam int allow null // Final Exam
and stored procedure like this:
ALTER procedure [dbo].[AddMonthlyMarks] ( @STDNo nvarchar(6), @CID nvarchar(7), @Dno int =isnull, @H1 int, @H2 int,..........................
the Data key name of grid is STDNo the problem is that the instructor this month will add only homework1(h1) for specific student number or to all students and rest of home works and quezies will not entered (Null), to the next month he will enter home work 2 ,etc... i get an error and i think that the null values for others home works in grid make this error caution: in table i check allow null property,the data type is integer How i can convert this null values to integer?
In one of webforms user must enter the percent of tax and then I convert it to the float number and finally save it into database. here is a sample:
Dim txtMyPercent txtMyPercent=Convert.ToSingle(txtPercent.text) label.text=txtMyPercent insert into(txtmypercent)
This peice of code, works perefect while runs via Visual Studio 2010, however after publishing, numbers are converted to integer. Thus it can't be inserted into Sql server database .... Server OS: Windows 2003 x64 IIS: 6 .Net Framework: 4.0
Currently using VS2008, VB.NET, SQL. I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.
I am grabbing the field from the FormView as such:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.
What I have tried so far:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label) Dim AvgTicket1 As Integer AvgTicket1 = Double.Parse(AvgTicket.Text) Do something with AvgTicket1
I have also attempted to Round the Value, then convert it and call it - no luck.
Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.
What are some methods I can successfully convert this value to an integer from a label?
I have a form that contains several textboxes and each one paired with a required validator. Each box reads a value from a dataset, and on submit click, update the database with the new value. For some reason, one of the validator always returns the error message even if I enter a value in the textbox. My code is something like this.
I am getting int values from the stored procedure. But when i bind this datasource with the gridview i am seeing the values being converted into float. i am using Text='<% # Bind("Quantity") %' I wanna that to be displayed as int, with out zero'seg: let the value be 233, when i bind that its getting displayed as 233.00
I want to validate a number by regular expression. Here is the requirement.
1- It should be between 1 and 200 2- maximum 2 floating point (e.g. 24.54 accepted but not 24.546) 3- the radix point can be either Dot or Comma (e.g. 29.45 - 29,45 both accepted) 4- can be intiger in this range also (e.g. 24 or 24.00)
Can anyone post an efficient regular expression for this?
I'm trying to execute this statement every minute with SQL Agent, I have it set up as a job:
It's trying to update a column which data type is set to decimal. Just so you know what I really need out of it, here is an example:
The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
