VS 2008 : Handle The TypeID In ConcernedParty Class?
May 3, 2011
I have a table called ConcernedParty. It has an ID field, description and a TypeID which is a foreign key to the pk TypeID column of a table names ConcernedPartyType.Now i'm creating two classes. One for each table. In my ConcernedParty class I have and ID, Description property etc. how must I handle the TypeID in my ConcernedParty Class.
Do I declare it as:
Public Property TypeID as ConcernedPartyType
Or
Public Property TypeID as Integer
I have a "partial" class in VB.NET. Half of it is auto generated by a code generation tool. That half implements INotifyPropertyChanged, so any properties in that part of the partial class raise the PropertyChanged event.In my "custom" part of the class, I declare another property that depends on one of the properties in the auto-generated side. Therefore, when that auto-generated property changes, I also want to raise a PropertyChanged event on my custom property that depends on it.
If I go into the generated part of the class and raise the event there, that will get overwritten if I ever re-generate that part, so I don't want to do that. I would rather add an event handler in my side of the partial class that checks if the generated property changed, and if so, raise another event for my custom property.

I'm assuming it's because normally you'd use the WithEvents keyword to tell the compiler that you're subscribing to events from that object. I don't have a clue how to do this inside of the class that's actually raising the event, or if that's even possible.
I'm trying to move some code into some class files to clean up my code. One area I'm having trouble with is reporting progress for events between the object performing the task and a progress bar. I guess the event functions have to be placed in the new class but they also need to update the progress bar on the calling form? Can the classobject return updates in place of the event handlers?
i have the ComClassSearchCustomers class and interface IComClassSearchCustomersat .net which used to create a tlb file. The class raise an event inside new. After that i have a vb6 form Form1 which catch the event , but it never see the event.
I'm converting a pretty large chunk of code into a Class so that it can be re-used more easily, but am having a problem with one of the Methods. I have a method that uses the following line:'GET HANDLE OF ANY POPUP WINDOW ASSOCIATED WITH MAIN FORM [code]The "Me.Handle" part won't work, but I don't know what to replace it with so that it knows to use the handle of the main application's form that is using the Class.Do I need to get all Process that match my application's and store the Process' handle?
I am attempting to share a sub menu among several different parts of an application so that it is consistent (not wanting to copy/paste.) I thought it would be simple. I am doing something like this:
if I wanted the button onclick event in a different class how would I declare it?
when I refer back to the form it says I need to declare with events..
Private Sub btnAddToLaneFilter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispatch.btnAddToLaneFilter.Click If Me.txtCriteria.Text = "" Then
I created a custom collection class with some methods: each of these has some parameters and throws an exception if a parameter is not valid.For example, the Add and Remove methods throw an NullReferenceException if one of their parameters is null.[code]...The Replace method replaces an item in the collection with another specified object: to reach the goal, it first calls the Remove method and after the Add method. Obviously the Replace method could throw exceptions if at least one of the specified parameters is null, because Remove and Add methods could throw exceptions.Is this the right way to go? Or should I also check the parameters in the Replace method as in the following code? [code]...In fact, in this second case, each check would be executed twice: first in the Replace method and after in the Remove and Addmethods, which are called by Replace, and in other cases the checks may be rather expensive.
I'm writting a class that needs the form handle but there is a way to use it without send it as argument in the class constructor or in a property?I know that the handler is not set until the form is completely loaded so that is another problem too.The basic idea is catch the form handle without pass it as argument and handle the wm messages.
I've been searching for the answer for a while but can't find it yet. Basically so far I have a simple VB.Net form with one button.I would like to make a class or module that can handle events from the main form. This is my code so far but it doesn't seem to work.
I want to use One routine to handle multiple events & i want to give the list class object to the routine handle clause in vb.net. Is it possible? I have 100 buttons on my web page & i want to handle click event of each button. I have same coding on each button but the only difference is that, which button is calling the event handling routine. So i want to make one sub routine for handling event of all my buttons.
I can solve this by writing each button name in the handles clause like - Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ImgRCP_26.Click, ImgRCP_27.Click,. But it is so lengthy procedure. So that why i want to handle my button in the arraylist. How to do this?
I have multiple user controls (the same one dynamically added to a form 4 times), and one class. I would like all of the user controls raise events in that one class. For example, if any of the user controls are clicked, I want it to send a string to the class to be processed and show a MsgBox "Control name was clicked"I am doing this as an exercise to reduce repeating the same code over and over directly in the control, and to avoid creating the class over and over to accompany each user control.
I have a standard windows application called winap. I have a com component which acts as an api to the winap. I have a class in winap call classapi which has all the methods that the api calls and all works well. The problem is that one of the methods in my class api needs to get a handle on form elements in the main worker thread. Whenever I try to access an existing form I keep getting null because the for exists in the main worker thread and my api call is in a seperate thread.
I have a section of code that will compile perfectly using VB Studio 2003, but it throws a InvalidCast Exception under VB 2005/2008. The code throws an Invalid Cast exception at KeyHandle = e(field.GetValue(KeyToMonitor) line below, and as far as I can tell it is because the variable Field is passing the string Microsoft.Win32.SafeHandles.SafeRegistryHandle rather than an integer. Is this because of safe keys in VB 2005 and 2008?
how to call the handle of the registry key opened in a way compatible with Safe Keys? I'm using the code to notify when a registry key is changed using RegNotifyChangeKeyValue.
Private Function WaitForChange() As Boolean Dim notifyEvent As New Threading.AutoResetEvent(False) Dim KeyHandle As IntPtr

I have a 'property management class' that contains several functions and properties. I have several other classes that use the 'management class' as a property to derive the value of several of its other properties.Is there a way for me to reference the outer class from the 'management class' functions without having to pass it as a parameter? I ask because several different classes can have this 'management class' as a property and am having a hard time typing the parameter.
I have a program which uses TcpClient, the issue I'm having is how do I construct the packets when some of them come in seperate parts. For example, If I receive 5 packets, 2 of them are fine, but the other 3 have come in seperate parts when it's suppose to be a whole packet. How can I handle this?
I don't know how much sense the title makes, but let me give you an example:If you've used Xfire, you may have run across links that allow you to modify things in the program such as your status.This is an example of a status changing link:xfire:status?text=I%20love%20Donkey%20Kong%20Jr.And your status will change to "I love Donkey Kong Jr.

I have a small program which loops records of one datatable against records of another datatable. I use a function that places two fields of the 2nd DataTable into an array. The problem I have is that if there is a NllValue in one of those fields I recieve an error message unable to cast Null to type Double.
I have the following code to handle keypresses on the form:
Private Sub Form1_KeyDown(ByVal sender As Object, _ ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown Debug.WriteLine(e.KeyCode)
[Code].....
The first time I press any of the arrow keys the code is not executed and a NumericUpDown(NUD) on the form gets the focus. The rest of the times the arrow keys are pressed everything is fine, until I click on a button. Then the problem repeats, focus NUD, then fine.
what's the best way to handle the updates to the database.For example i have one datagridview that's binded to a datatable (with two fields, id auto incremented and a varchar). The user can do all the operations Insert, Update, Delete.If i insert one row (only the text) and call the update method to save the changes to the database, and after that remove the same row and call the update method the adapter will throw a exception because it didn't update the datatable with the value of the id. So the best way to do this is always calling the fill method after every update?
I have a DLL that copies an Access database, opens it, reads it, and then closes it. The second time through it is unable to copy the Access DB because the EXE has an open handle to it. The EXE does not reference the Access DB at all, it just has the open handle because it calls my DLL. After I close the DB, I would like to terminate the EXE's handle to the Acess DB. BTS - I wrote the DLL and it is my Access DB. Another company wrote the EXE and I can not make any changes to it.
I wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:
main form handle: 15
component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?
Is it possible to send keys to a specific windows handle without having to bring that window to focus?Right now I have the following code almost doing the trick:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Private Declare Function SetForegroundWindow Lib "user32" Alias "SetForegroundWindow" (ByVal hwnd As Long) As Integer Sub SendKeysToApplication(ByVal AppTitle As String, ByVal Keys As String)
[code]....
