Using Threads In Menu Options?
Mar 29, 2010
I have an app that has a console menu with 2/3 selections. One process involves uploading a file and performing a lengthy search process on its contents, whilst another process involves SQL queries and is an interactive process with the user. I wish to use threads to allow one process to run and the menu to offer the option for the second process to run.However you cannot run the first process twice.
main...
Dim tm As Thread = New Thread(AddressOf loadFile)
Dim ts As Thread = New Thread(AddressOf reports)

I would like to have threads created and perform selected operations for a menu. Basically there are 3 options and for each option, a thread should go ahead and perform that operation whilst the option is available to select other options if the operation is running and not interactive. I have tried it and after correcting a lot of compiler errors its not running correctly with one thread hanging and not giving the option to select another process.

As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.

I want to learn how to add the menu options that appear when you click your right mouse button.So far I have a normal menu strip control, rich text box control and I have added a ContextMenuStrip control.
I have not got a clue on how to set the properties for the contextmenustrip on the richtextbox control, so when the user clicks the right mouse button the contextmenustrip appears.

The user right clicks on my picturebox object. Good.When that happens, some code of mine executes and will generate a list of options.Then a menu appears where the mouse right-clicked, made up of these options.When the user clicks on one of these options, the menu is deleted and some code is run given the option index as parameter.How can I tell when the user right clicks? I can see an event handler for "click", but that includes left clicks.How do I create one of these menus? I mean, go ahead and right click something. That's the kind of menu I'm looking for.

My latest project is to write an app that has a drop-down menu where I can choose different office locations. Once a choice is made I want a handful of different buttons which would vary between location choice. When a button is clicked it will install a printer. I've got the button and install part down but don't know where to start with the dropdown and showing different options upon choice.

i have various options in my app, some complex some not, these 2 save on application exit and reload on application start themes, and layouts. There selected via a comobox each.So onto the question, how does everyone create options menus? With out using a menustrip/toolstrip?
The method i was using , was to have a picture box show a panel when it was clicked on, the panel had all the various options etc on it. This idea worked great, but meant working in design mode was a pain because the panel and everything on it had to be moved round to see the items under it on the form.
So today i decided to see what other ways i can implement a menu, and i changed it so the picturebox/button now opens a dialog, and all the options etc are on that dialog, this works great except options such as the combobox 1 and combobox2 last used setting (text data binding) doesn't load when the application is started, they only load when you go into the options. Which defeats the point, if a users going into the options just to load the settings its useless them been saved.
The time to initialize the dialog (for it to appear and be click able) is 5 - 15 seconds, not alot i know but the 1st method of using a panel it initializes instantly, but then its never really closed just made hidden, so i uses more system resources.So how does every one else implement there options menu?

I have a text box field for which I want to use a couple of custom commands accessible via a context menu. I can add my custom context menu to my text box, but then I lose the standard windows ones (i.e. Undo, copy, paste, etc).
What I really want is a context menu with both my custom options and the standard windows options. I want that to take place only within my application (i.e. not like a shell extension).

As you can see from the screen shot I have managed to get MDI Parents / Child forms working, and managed there to be a menu option on the Parent form that displays all the Child forms opened at the time. What I was wondering, and as of yet through research haven't discovered, is there a way when the list of windows is created, if a user highlights any child in the list it opens a sub-menu from its name (eg. Rename Window, Center Window, etc).

I have this code below that I called a Conversion Wizard Because it converts temperature, weight and currency. It works so far but I am stuck. I don't know how to apply the correct loops to it. For example, Do While and Do Until. I want it to be able to work out a conversion then loop back to the Menu-options. So that you can do as many conversions as you like and end when option 4 is selected.
Option Explicit On
Module ConversionWizard
Sub Main()
Dim userOption As Integer
Dim farenHeight As Integer

I'm using the code from the following site to create a file manager within my app: [url]Which, I think is great. When I first started programming, I wanted to use this code, but I couldn't understand it. I love how now, I understand most of it and know how to implement it. Which, I owe much of my progress to some of you at this site Well, back to what I was saying. I want to be able to make a right click menu and have it access options like copy, paste, etc. I'm sure I can figure that out, but I can't seem to figure out how to make a right click menu.I thought I could manipulate a menustrip, but I wasn't sure how.

I am creating a VBA application using Excel 2007 and would like to make virtually all of the standard Office and Excel menus invisible to the user and present to the user only my custom menu controls. I have been successful in doing this for all objects on the Ribbon as well as those on the Microsoft Office Button Menu, with the exception of the "recently opened files list" box, that also has the "Excel Options" and "Exit Excel" buttons on it. Can anyone tell me the name of the object for this control so that I can make it invisible?

Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.

I am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.

I just had a new, last-minute idea on to take on a task, so I am running to StackExchange for quick help.
What I want to do is execute a series of methods right in a row, each in their own threads. I want the application to wait until all of these threads are completed, after which the program will resume. It also has to use managed threading (thread pool).
What quick examples could you provide to help me along the way? If it's too complex, what things should I know about so that I can Google it on my own?

I have a main thread which is designed to be a batch processor - it spawns a series of 'child' threads from a loop (which can vary in terms of the no of items) - see below
[Code]...
However, each of the 'child' threads could take anywhere from milliseconds to about a minute to process - depending on the complexity of each calculation. There may also be a large number of child threads - e.g 100s. Creating large numbers of child threads is not efficient. I therefore want some way to effectively queue each child thread (and cancel if the process is taking too long to complete). Autoevents seems like one way of doing this, but the only examples I can find seem to assume there are two different processes on seperate threads, not one process being repeated.

How do I make a menu item on a menu strip link to another windows form (like a menu item that links to an about page already created in the project). I know that every coder knows how to do this, but i've read most of the instructions in the world for Visual Basic coding, but can't find ANYTHING I know coding fairly well, so I can modify it, but I can't create it my self.

I have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.

This is going to be hard to explain but oh well.I have a form with a menu. When I hit option one, it opens another form (form2) inside that same form (mdiparent). When I hit X on form2, then try to open it again from the original form with a menu thru the menu, It says it cant access a disposed object. Here is the code: Form1:
