Where To Start In Terms Of Making Those Options Get Pushed Down / Come Back Up
Jul 11, 2011
I'm just starting to use vb .net (using 2008 express edition) and I want to make a menu for my program that will be like a sidebar that when you click one of the options, a few sub-options will fold out that will push the main options below downwards - and then the sub-options will disappear and the options will go back into place when something else is selected.I am not sure exactly where to start in terms of making those options get pushed down/come back up..

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

what I mean, every full-featured program has one. Tools > Options brings it up in Firefox. First off, I've looked for tutorials on making these and can't find them anywhere, does anybody have any links? Second, I'm making mine with a TreeView and panels. The problem is designing this thing with all of these overlapping panels! It's crazy. So, how do you easily make an options menu like Firefox where clicking on different tabs brings up different data options?

Is it possible to open another app without losing focus of the current foreground app? I have a program that will open another app and test something on it then close it, and reopen it again and repeat. Can this be all done in the back while i am typing away on another app in the foreground without getting interrupted by the new app opening and changing focus?
i dont want the new app open minimized or anything, just quietly open in the background.
I tried using process startinfo.windowstyle and that doesnt help much.

I accept both C# and VB.NET If you visit this [URL].. and then click on the link like the image below you'll see in-line pop-up DIV which displays a busy status of Ajax callback before it displays the information. So, the information is not there yet until you click on the link.
I'd like to do the same but ASP.NET and jQuery. If there's any place to help me get started on the right track?

I've got a function api_request which takes API method as an argument, and returns XMLTextReader.
Shared Function api_request(method As String) As XmlTextReader
request_text = method & ".xml"
url = "[URL]" & request_text & "&access_token=" & token
Return New XmlTextReader(url)
End Function
I call this function from different places to make request to site API and depending on the method results are parsed very differently. So in each method I have something like this:
Dim s As Xml.XmlReader = api_request("users.get")
While s.Read
If s.NodeType = XmlNodeType.Element Then
If s.Name = "user" Then
[Code] .....
As you may see, I have the code ElseIf s.Name = "error" Then error_handler(s, "user.get"). This is because when error happens, server always returns something like this:
<error>
<error_code>4</error_code>
<error_msg>Incorrect signature</error_msg>
</error>
This is parsed in error_handler Sub, and depending on the error following actions are chosen. This code works, but I have to check if I encounter error like that ElseIf s.Name = "error" every time, though all the methods call the api_request function. Is it possible to check for error in api_request function before returning the Reader? The problem is if I start reading xml there, and there isn't an error, I can't anyhow position the Reader to the start.

I would like to make a method excute right before the user get back controle of the program. No matter what chain of events happens i would like to beable to have a method is always the last thing to excute. I plan on using the method to check the form and the data on it. I have no issues righting the method, I just don't know if their is a event or some other way to make sure it is always the last thing to excute. (Sorta like a validation method) Is their an easy way to do this?

I'm really interested in programming things for games (NOT cheats, more or less things that make the gamer's life easier) and most of my ideas end up relating to an OCR, but I've got no idea where to start making one or how to make it at all, really.
I did a quick google search but all I could find were libraries to convert bitmaps and such to strings, which is not what I want. The game I'm making this for specifically is browser-based, so unless I were to take a screenshot there wouldn't be much to work with since there's a ton of text in addressbars and such.
The main focus of my OCR is to allow automatic PIN entering for banks in the game (PINs are used for security purposes, but lazy people don't like entering them). There's a keypad on-screen with 9 boxes, each with a number, but after every click the numbers change positions inside the buttons and they also switch positions with other buttons (note that the buttons stay in place and do not change color or anything).

I have a program that requires a string. The string is 20 characters long. The string also have to be split into 2 words the first word is 12 characters and the second is 8. If the strings is not 20 characters long I get an error. I wanted to know how can I get the program to start back over and let me enter another 2 more words if the string is not 20 characters long. At the moment after I get the string is not 20 characters long error it continues to read the rest of the program but I want it to stop after an error and let me start over from the beginning.

I am making a maze game like the one shown in the how to, I recently discovered that if you hold the right mouse button a you can go through the wall. Is there a way to make the mouse lock and not move when the user trys to hold the button down
or
When the user releases the button it resets. Like in the web browser with
If e.KeyCode =
Keys.Enter
Then
e.SuppressKeyPress =
True
WebBrowser1.Navigate(ToolStripTextBox1.Text)
But with the mouse button when it releases send the cursor back to start.

I have a program that has a large weather map which is 1920 x 1080 resolution. The start location is (0,0). I want people who use smaller resolutions to be able to see the whole map. I would like to create a button that allows me to shift the form down or right say 10 pixels each time the button is clicked. How would I do this?

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.

In design mode, I have 2 forms, Main and Profile. Both have many controls on them.When executed, the Profile form is duplicated 4 times and named Profile1 through 4. Among the controls on these forms are 3 buttons that copy the selections from the other 3 forms to the one that had the button pressed.How do I accomplish this? I don't understand how to let the method know which form is getting it's buttons pushed so it knows what form to copy...
