I'm looking to find out the most efficient pseudo-code in order to achieve the following conditions:
I have an "event" which has a start and an end date (S1, S2). I am try to find out if this even occurs within a specific timeframe (D1, D2). If the event only lasts for one day, it will not have an end date. I only want one occurance of the event in the query.
If anybody is able to assist with tbe psuedo code behind such a query, I'd be grateful.
I'm having trouble with an SQL statement. I want to have one statement that checks to see if it a record exists. If it does, then update it and if it doesnt then insert a new one in the server. Here is what I have so far:
I have a page that inserts a record to an sql database and I would like to do the following:
(i) Check if a record already exist before trying do an insert
(ii) If a record exist, the page should be able to inform/display a message in a textbox informing the user that the record already exist.
I have seen a number of post on the internet that suggest that one possible solution is to write a sproc and use the T-sql IF EXIST function. However, I have NOT seen a complete code showing (a) how this can be done (b) how to call the sproc from an asp page (c) and MORE IMPORTANTLY how to display a message informing a user that a record already exist i.e. when the record already exist in the database.
and i am facing problem while inserting the record.
eg:
if the room is already booked from 1st march 2010 to 10th march 2010.and if anybody is booking the same room from 4th march to 9th march it should show error message stating that
this room is already booked from 1st march to 10th march.
I am using a form to add and edit record of database.
In Add case my email box has no value. I have used customservervalidation to check the given email address with previous database records.
In Edit case my email box is populated with data from database.
When i click save button in both cases my customservervalidation method invokes and checks the given value. it works fine for new/add case but in edit case it checks with itself also and says duplicate email... pointing own record...
what i have is a dropdownlist1,chekbox1 and objectdatasource1 for getting the select query
what i need is checkbox values should fetch the values of table a and displayed inside in dropdownlist1 and values are checked dynamically and the checked values should be shown in gridview1
if any body knows the full code reply the code or mail me ponmanivannangj@mobiusservices.in
How can I select multiple dates in the calendar?If I selected multiple dates and added them into DB,, Is it possible to view them again in the calendar (i.e. the dates will be selected and colored)?
I have a requirement that i need to select the multiple date range.like if i select the date 21 to 26 , in that case i dont want to deselect the date in between. the funcanolity i saw in the [URL] web site where you fill the parameter and according to that parameter you find the calander.
I have a calendar that can have multiple dates non sequentially selected. I have a gridview on the page with a sqldatasource control bound to it.
Again, I have already built the events calendar with the ability to select multiple dates... now I just want to show those detailed records below the calendar for only the dates selected.
How do I filter the records to only get the records of the SelectedDates of the Calendar control.
This has to be done dynamically in the code behind.
When the user hits the Enter Key I want to go through and validate some fields and kick it back to the user if a fields doesnt' validate. With the above code, the btnEnter_Click still is getting called even though I have it to return. I tried return false; too incase I misunderstood something.BTW, yes the code is falling into the Else Statement when stepping through code.
I need some pointers to start on this.We are building a time off application where three instances of a calendar control will be displayed ( prev - current and next month) now users can click on various dates accross all three instances and then a count of number of days should be diaplyed in the parent textbox.
To begin with this, i started with adding the dates clicked by the user in Calendar2_SelectionChanged method into a list<> so that i can get the all dates user clicked and then add it to calander's selected dates collection. But this throws an e" object reference not set" error.
Is there anyother way to get all the dates that user click onthe calendar( note the dates doesn't get highlighed so seleteddates doesnt work)does anyone has a good example for this.
i want to use a ajax calender extender in which when user clixcks on button caleder show only dates of current month not previous dates.i dont want to disable dates. i should not apper on current month calender. means it should start from 1 and end to 30 or 31
once a user select an item from dropdownlist > Dates from DB are shown on calendar in pink color.
The problem now is when i want to select new dates the selected dates(in pink) become deselected .. I want them to stay selected so i can know which dates are already used .
i have to date say in MM/DD/YYYY format "1/1/2010" and 1/30/2010". now i want to find dates which comes on monday. so out out will be 01/04/2010, 1/11/2010, 01/18/2010, 01/25/2010
I am generating multi-series graphs with the date along the X-Axis. The problem is that not all of the series in the graph have the same dates in the date range. Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range. This skews the charts I need to create. Go, given the date range taken at the begining of the query I'd like to generate a list of dates and populate the data to be graphed, padding those series with 0's for those dates that have no data.
How can insert, Display ,update multiple records simultaneously through GridView in Asp.net.I have Button for insert, update . I want insert, update multiple records through a GridView in a single click.
I am going to insert Multiple record IN sql using storedProcedure from gridview...
for this purpose i am using cell concatinating method and send whole gridview cell data in string variable.
i have tried xml document method or sending data in table through looping as well but didn't satisfy from both of them... b/c concatinating method required a delimeter for seperation(for which i have restrict the user from that sepereator ) and xml method required an extra file which is not a efficient approach .
I have a InsertCommand function i am using to insert the dropdownlist in my updatepanel. When the Add button is clicked. It adds the record multiple times. Am not sure why it does this. Here is my code.
Dim Bank_number As DropDownList = UpdatePanel1.FindControl("ddlbank")Dim NoteAccountNumber As DropDownList = UpdatePanel1.FindControl("ddlAccount")' UpdatePanel1.ChangeMode(FormViewMode.Insert) lblsee.Visible = "true" 'now collect selected information on the drop down RelationshipTest.InsertParameters( RelationshipTest.InsertParameters( "bank_number").DefaultValue = ddlBank.SelectedValue.ToString"noteaccountnumber").DefaultValue = ddlAccount.SelectedValue.ToString'Insert into db RelationshipTest.Insert()
Also, i was woundering if any of you might know the logic behind clearing inserted data from the dropdownlist once its inserted. I am trying to make sure data is not entered mulitiple times. Unique Indexing comes to mind but thats only on the backend.
