Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window.
All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;
}

The case is that I have two comboboxes (country and state) and a simple code to populate the state combobox accordingly depending on the selected country. Ok this is simple and easy, and this code is within the country combo change event.The case is that I have more than one pairs of those comboboxes and I wouldnt like to repeat all the populate code into every country combo change event.Actually I would like to have only one function and just call it passing as parameter a reference to the combobox I want to populate. Then I could use that reference into the function.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ?
or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed.Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function:
Module Module1
Public Function LookUpNow(ByVal userInput As String) As String
LookUpNow = userInput
Return userInput

My problem is that i dont know how to define the parameter type for the sub. Because they are different types of objectSets being passed each time, I thought IObjectSet(Of EntityObject) would work, but it gives me the following error:
Unable to cast object of type 'System.Data.Objects.ObjectSet1[licensingModel.tblLookup_Country]' to
type
'System.Data.Objects.IObjectSet1[System.Data.Objects.DataClasses.EntityObject]'

I need to pass an event as a parameter to a function and I'm wondering if there is any way of doing this.The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this. As an example, let's say I have a combobox in my code called combobox1, and I have the handler called indexChangedHandler. In several places of my code, I have the following two lines:[code]Now, I don't want to keep on repeating the above two lines of code (or similar) all over my program, so I'm looking for a way to do this:[code]So far, the "evt as Event" part of the argument of the setHandler function is giving an error. Any ideas on the right way to do this will be very welcomed.

I need to pass an event as a parameter to a function and I'm wondering if there is any way of doing this.
The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this.
As an example, let's say I have a combobox in my code called combobox1, and I have the handler called indexChangedHandler. In several places of my code, I have the following two lines:
RemoveHandler combobox1.SelectedIndexChanged, AddressOf indexChangedHandler
AddHandler combobox1.SelectedIndexChanged, AddressOf indexChangedHandler
Now, I don't want to keep on repeating the above two lines of code (or similar) all over my program, so I'm looking for a way to do this:
Private Sub setHandler(evt As Event, hndler As eventhandler)
RemoveHandler evt, hndler
AddHandler evt, hndler
End Sub
so that everywhere where those two lines of code(or similar) occur in my program, I can just replace them with:
setHandler(combobox1.SelectedIndexChanged, AddressOf indexChangedHandler)
So far, the "evt as Event" part of the argument of the setHandler function is giving an error.
P.S I've asked this question on a couple of other forums and keep getting asked why I would want to set the handler immediately after removing it. The reason is because dynamically adding an event handler n-times causes the handler to be executed n-times when the event occurs. To avoid this, i.e to ensure that the handler is executed just once when the event occurs, I first remove the handler each time I want to add the handler dynamically.
You might be asking why the handler would be added several times in the first place... The reason is because I add the handler only after a particular event, say E1, in my form has occured (I add the handler within the handler of event E1). And event E1 can occur several times within my form. If I do not remove the handler each time before adding it again, the handler gets added and thus executed several times.
Whatever the case, the processing occuring within the function is not of ultimate importance to me at this time, but rather just the means of passing an event as a parameter.
