Passing A Variable To An Action In JQuery?

Nov 29, 2011

I'm using MVC2 with jquery.I'm trying to open a partial view in a jquery Dialog container, passing an itemID of an object to be deleted.What I'm doing to accomplish this is passing in an action that renders a view to jquery, which I can get to work without variables.f I try to pass in the ID of the object to be deleted, the action doesn't even trigger.

Here's my jquery code:
$(function () {
var itemToDelete

Passing A Variable To Another Form / From Another When Invoked By Action

Feb 23, 2012

I have a form in Visual Basic that is adding a row of data to an Access Database.What will happen (or rather what I would like to happen) is that when the form is created, a row will be added to said database. Once that row is added, I want to have another form open (called NewWindowA) which will pull information on that database that is related to the ID of the row that was created from the first form.I know that in NewWindowA I need to have the form load the values on Load. But my question is: How do you pass a value to a new window that's invoked by some action?

Forms :: Execute And Action When Passing A Certain Value

Apr 22, 2009

I'm making a simple game as my first personal Visual Basic program, and I've run into a small problem. I'm trying to make it so when you reach or pass certain amounts of experience, you receive 5 stat points, but the best I've been able to do so far is have the program add the points when you are in a small window of 2 values. This is what I have now:

If Val(lblTtlExp.Text) >= 100 And Val(lblTtlExp.Text) < 110 Then
lblStats.Text = Val(lblStats.Text) + 5
ElseIf Val(lblTtlExp.Text) >= 200 And Val(lblTtlExp.Text) < 210 Then

Jquery - Passing Client Data To Server To Create Excel Or CSV File?

Jan 9, 2012

I'm creating a reporting web page as part of a standard VB.NET web application. The page is data driven, with jquery making calls to a web service local to the application to get values of elements that are dynamically created in the DOM. Ultimately these dynamic elements and their values are all wrapped up in a JSON object, so that part of the client side is fine.

Right now, I can pass that JSON object to a method in the web service which creates an SQL Data adapter from the values and queries a database. My ultimate goal is to have this client JSON data be used to query the database and construct an excel file to send back to the user, or failing that a CSV file.

It's my understanding (from working with PDF file generation) that this type of function can only be done on the server side of the web application, not even from the web service (i.e. I can't have the web service return an array of bytes and have JavaScript/jQuery present that as a file).

So, how do I go about this? Now I have my JSON object on the client side, where should I be sending it, how, and how do I go about returning my file?

I've read about either storing the JSON in a hidden field and having the server take the elements value and go from there, or using AJAX to send the JSON to the server just before a postback is made to fire off the server-side function to run the query and return the data.

I just need a little guidance, and a little help understanding where to use the hidden field, or what I am actually doing with the pre-postback AJAX call.

.net - Silverlight Datacontext, Repeats All The Past Commands/action Each Time A New Action Is Performed On It

Mar 28, 2011

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally

this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out

Pass A Variable's Name Along With The Value When Passing Through Functions?

Jul 6, 2009

I want to know if it's possible to retrieve the variables name from when it was passed into a certain function. For example, if I call parseId(myId) to a function with the signature parseId(id), i can obviously retrieve the value of 'id'. However, is there any way I can retrieve 'myId' as a string (without passing it as another value)? Specifically in vb.net, but I'm interested in how it would work in any given language.

Passing Variable With DBNull Via INSERT INTO

Jun 22, 2010

I use VB .NET 2002 (academic version) I have created an MS Access database to be populated with vaules extracted from dBase files. Some numerical values can be null - ie where no data was recorded in the dBase file. Relevant field properties in MS Access mdb table are set to "Not Required" as follows - dt0 is the name in code of the Access table "AllData":

With dt0.Columns
.Append("Date", DataTypeEnum.adDate)

colTest.Name = "Ch1Deg"

[CODE]...

Using an INSERT INTO command I can send a null value to the field:

SQLMdb = "INSERT INTO [AllData]" " ([Date],[Ch1Deg])" & _
" VALUES ('" & dDate1 & "',null)

My problem is how to pass a variable which sometimes takes the value System.DBNull.

If I use SQLMdb = "INSERT INTO [AllData]" " ([Date],[Ch1Deg])" & _
" VALUES ('" & dDate1 & "','" & dDeg & "')

Then when dDeg is numeric then there is no problem and the table is populated. When data is missing and dDeg takes the value System.DBNull then it's a no go! The error message is "Data type mismatch in criteria expression."

Is there a way round this with VB .NET 2002 or do I need to upgrade to a later version which has nullable data types, eg nullable integers and doubles etc?

Class Variable Assignments - Passing Values From S1 To S2

May 31, 2011

I am trying to work with classes and variables and don't seem to understand some behavior that is going on.

first off the class
Public Class csSession
Public ID As Integer
Public Name As String
End Class
Usage and behavior (example code)
Dim S1 as new csSession
Dim S2 as new csSession
S1.ID = 1
S1.Name = "1st Session"
S2 = S1
S2.ID = 99

When I assign S2 = S1 all the values of S1 passes to S2 but also there is a "link" or bond between the two variables now. If I change the values of S2 this automatically changes the values of S1!! Why does this happen and how can I prevent it? I just want to pass the variables values contained S1 to S2.
