Feb 12, 2011Private Sub SpecialMenu( ByVal ddItems As ToolStripItemCollection, method as ??)
...
AddHandler ddItems(item).Click, AddressOf method
...
How can I pass a sub address into a subroutine.
I understand delagates but not enough to figure this out.
I have a sub that creates and adds menu items to a menu and I need to use it in more than one project so I want to put it into a library.
But I don't know how pass it the address of the subs to attach to the new menu items.

Forms :: Pass UserControl As An Argument?
Sep 8, 2010I've got several user controls and every time I add them, I post this
Dim uc As New ucTemplates ' 'ucTemplates' is the name of the actual user contrll
gbControls.Controls.Clear()
gbControls.Controls.Add(uc)
So, I'd like to create a sub that does the same thing, passing the usercontrol as an argument
Private Sub AddUC(myControl as UserControl)
gbControls.Controls.Clear()
gbControls.Controls.Add(myControl)
End Sub
But - when I try:
addUC(ucTemplates)
I get an error that ucTemplates is a type and cannot be used as an expression
I can get it working if I add the Dim uc As New before the addUC - but I'd rather have it so I only repeat one line, not 2

View 6 RepliesPass An Array Of Arrays As A Function Argument?
Nov 11, 2010I have several parameters consisting of separate System.Byte() arrays. What I need is the syntax for a function declaration where the parameter is an array of arrays - I do not want to delve into System.Collections, and it's my preference not to CType each array into an Object and then back into a Byte().
Problem I'm having here is that:
Public Function MyFunc(arrayparam() As System.Byte) As System.Byte()
accepts a single-dimensional Array of individual Bytes.
Then Public Function MyFunc(arrayparam() As System.Byte()) As System.Byte()

View 6 RepliesUse Form Handle In Class Without Pass It As Argument?
May 3, 2012I'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.
View 2 RepliesPass Combo Control Between Events?
Jun 4, 2009I'm using VS2008, vb.net, and winforms. I've got 3 comboboxes on the same form who are all bound to the same data. If an item is added in one, I want the change reflected in the other two. I'm trying to create one sub to handle the adding of an item for all three combos. I found that the "sender" object appears to contain the control name. The Sub I created is not working quite right because after the item is added, the combo list display repeats itself. So instead of "Item1, Item2, Item3" after adding "Item3", I get "Item1", "Item2", "Item1", "Item2", "Item3". This coding works fine if I were to copy it to the Key_Down event for each combo and reference it directly (for example, use cboSpecialty1.Items.[code]...

.net - Understanding AddHandler And Pass Delegates And Events

This code is generating a run-time exception stating: Unable to cast object of type 'MyEventHandlerDelegate' to type 'System.EventHandler' What am I not understanding about System.Delegate even though AddHandler takes as an argument of type "System.Delegate"?

Pass A Handle In A .NET Form To C For It To Draw On/get Click Events?
Jul 20, 2009I am trying to put a new face on an old C program. The C program is, of course, unmanaged code, designed smartly to separate the number crunching and the interface, and the interface I'm trying to replace is X windowing. The graphics part is where it gets a little hairy, because the C is going to need to continue to draw in my new interface, based on the data the program produces. Even if I want to duplicate that data in .NET so that the .NET side can handle all of the drawing, the fact remains I'm going to need to operate on the graphics window in some fashion from C.
I gather that handles have a lot to do with the bare Win32 graphic operations. Is such a similar handle provided to, say, a PictureBox element in .NET? And if so, is it the kind of handle I can use in the unmanaged code without an issue?
I have tried and tried and tried to google for the solution for weeks now, and all I come up with are either C++ solutions (using object-oriented GDI+) or some sort of extension to the C language.
Alternatively, is there a way I can have .NET create a handle specifically for this purpose of having C draw it?
To sum it up, I am using Visual Basic .NET 2008 and a C DLL (also compiled in VS2008), so far in the little testing I've done, I've been able to marshal complex structures to and fro, but I am not sure how exactly I'd let C do any drawing on the .NET form, if that was even possible.

Pass Data To Dialog - Manipulate And Pass Back?
Jan 15, 2010Just 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.
Mouse Events And User Control - Control Won't Respond To The Events
Dec 31, 2010I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.
