Pass Data To Dialog - Manipulate And Pass Back?

Jan 15, 2010

Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.

3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:

Code:
Public Class Form1
Dim clsController1 As New MotionController

[code].....

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.

Pass Strings From VB To C++ DLL And Back?

Currently this code runs without exception, but desc shows 40 spaces when displayed to the messagebox. I've tried StringBuilders, but they don't seem to work. I've also tried changing the 2nd parameter to be ByRef but this causes a read/write memory exception.

Pass Values Back And Forth Appdomains?

I thought make this would make my ada.myString have "working!" on the main appdomain, but it doesn't. I thought that by inhering from MarshalByRefObject any changes made on the 2nd appdomain would reflect also in the original one(I thought this would be just a proxy to the real object on the main appdomain!)?

Mvc - Pass Model From Typed View Back To A Controller Action

Aug 10, 2010

I have an MVC application where all the data is tied together by VisitDate table in my database. The home page is a strongly typed view of type VisitDate, all it does is pull up some simple data. Now, here's where I'm having a problem. I need a link that passes the current model in the view back to a separate controller action so I can render a different page with different data. Here are my two controller actions. I'm going from News.aspx to FrontPage.aspx and hopefully passing SchoolVisit. [Code]

Using Delegates To Pass Information Back To UI From Custom Socket Class?

Oct 6, 2010

I am in the process of prototyping a small sockets application, which monitors IT infrastructure (due to in-house financial and deployment restrictions, I am unable to utilise an existing commercial or open-source solution). Basically, I have a server application and associated agent process for communicating heart-beat data to the server. The server application implements a TCP socket class (TCPDevice), which is called from a WinForm. I am aware of the restriction on updating the UI from processes running on separate threads, and that the preferred technique for acheiving this is via the use of Delegates in conjunction with the Invoke method. Having had very little need previously for using Delegates (apart from of course std windows events and the BackGroundWorker control), I am at a loss as to how to do this in the context of my application, and would appreciate some assistance, although it has occurred to me that I could use the backgroundworker for marshalling updates to the UI.

Eventually the application will need to update a grid of devices via feeds from the defined agents, however for the purpose of this exercise simply updating a status bar on the UI will suffice. The section of the code which I believe is relevant to propogating the code to the form is contained in the OnDataReceived method.Below is a code excerpt from the protoype app which should put the above into appropriate context:

Asp.net - Pass Cancel Or Update Button Click From Popup Back To Parent Page?

Apr 25, 2012

I have a popup aspx page that receives data from a parent page gridview Edit click. There is a great deal of parsing of data from parent page to pop up as the data is being translated in pop up, then sent back to parent page to be reassembled in the original text block before update.

When the popup passes the data back or is canceled, the parent page gridview is still in Edit mode.I would like to pass the Cancel or Update button click from the popup to the parent page gridview so it can complete the update or cancel event without asking the user to click the corresponding command button link from the gridview edit mode, to Update or Cancel.

UPDATE: There is also a jquery UIBlocker on the Parent page to prevent the user from returning to the page until the PopUp page processing has been completed. Below is the critical code:

PARENT Page:
function parentFunc(a) {
// Unblocks on return from popup page.
$.unblockUI({});

[code]...

Had a problem with preventing the popup from reloading. So there is an if condition in the load event. A dynamic number of controls are built on the popup as literals. So the Page Init event and Page Load event fire on non Postback to rebuild the controls.
