EDIT: Ok, I found the Groupbox Control but how do i use it? should i just drag other controls inside it or i should add controls directly into it?

i've been trying to make a simple web browser, but i've been trying to have it run on WebKit because IE sucks. The first form is where the user enters in a product key, and after they enter in the correct key, it's supposed to open up the next form containing the actual web browser, except this is where i'm getting errors.

On a Windows Form in .Net 3.5 I have created a menu object and populated it with ToolStripMenuItems. One of these items has a DropDown object attached. The DropDown should appear when the mouse hovers over the parent ToolStripMenuItem and disappear when the mouse leaves the ToolStripMenuItem unless it is "leaving" the parent by entering the parent's DropDown.Also, I don't want the DropDown to automatically close when the user makes a selection in it, so I have set its "AutoClose" property to False.
Getting the DropDown to appear was easy. I just set up a handler for a "MouseEnter" event on the parent ToolStripMenuItem. But I'm stuck trying to make the DropDown disappear at the right time. If I set up a handler to close the it when the mouse leaves the parent ToolStripMenuItem, it becomes impossible to use the DropDown, because moving the mouse into the DropDown means "leaving" the parent ToolStripMenuItem, and so the DropDown closes as soon as the user tries to hover over it!
I haven't been able to figure out how to detect if the mouse has really left the whole ToolStripMenuItem / DropDown assembly (in which case the DropDown should close) or has only "left" the ToolStripMenuItem by entering the DropDown (in which case the DropDown should not close).This seems like a common design - a drop down that appears / disappears when the mouse hovers over / leaves the parent element - so how is it normally done?

how to implement such a thing , i am currently programming a compact framework vb.net this is what i have done and am stuck,what ive learn is very basic and simple i am using a sqlce query to use it to search for any string matching entries in the database and then it will display it something like google search engine.And am using visual studio 2005, what ive done is that i will use the datareader to search for the rows in the database and then i will have to assign them to something that is similar to google search engine a dropdown list of similiar results but am not sure how. What im doing is for the user to search for a particular salesman name and then have a progressive search function to also help the user to complete typing rather than typing the full words

I am very new to VB.net and I am having a hard time figuring out this error. I am using Visual Studio 2010.
The error is like this[code]...
I am also attaching all the files need to run this program. Please help me because I have been scratching my head for more than a week without any success.
The inorder traversal is working fine, but when I implemented the Breadth First Search Traversal to show the output of a numbers by level, then I started getting this error because I implemented new queue class (clsQueue.vb)for this.

As I design my system using VB.NET with SQL Server/T-SQL I'm always struck by what seems to me an obvious gap, namely VB Class Properties. Say I have a table Employee with columns: [code]In VB I might have a class like:[code]So my property SpeaksAForeignLanguage depends on two fields currently. Perhaps someday this will change and more fields or conditions might come into play. THAT'S THE WHOLE REASON for using properties.Now if I need the equivalent of my property in SQL for whatever reason there's no way to do it other than to recode some SELECT statement using the two Knows... columns.

I am working on a plugin architecture and after some reading I have settled on one. The host class will be implemented in C# as well as some of the plugins for that host. The issue I am having is that some of my team uses VB.net. So the question, is it possible to implement a C# (plugin)interface in VB, such that when it is dynamically loaded into the host program it will have the methods required by the interface.

Dim SPECIAL As Acronym = "Strength, Perception, Endurance, Charisma, Intelligence, Agility, and Luck." The game I'm working on is going to use this style of system.
What I need to do is:
1. All SPECIAL values have to be between 1 and 10. [DONE]
2. When adding and subtracting from any SPECIAL; update remaining points accordingly.
3. If remaining points = 0, then you cannot increase any SPECIAL.
4. If remaining points <> 0, then you cannot continue until all are spent.
I'm up to task 2, but having some difficulty.I managed to figure out how to do it for one. For example:
Sub Numeric_Up_Down_Strength_Value_Changed() Handles Numeric_Up_Down_Strength.ValueChanged
Label_Remaining_Value.Text = CStr(10 - Numeric_Up_Down_Strength.Value)
End Sub
But I'm having trouble figuring out how to make it work for all. I've had some ideas but upon trying to implement them I've been having data type conversion errors.

I'm new to ASP.NET MVC and need abit of advice on how to implement the following.The site is a heavily used site with roughly 200 users internally (intranet). We use forms authentication hitting a SQL Server DB (not windows integrated).
Some actions are protected, some are viewable by anyone and some are viewable by both - so if theres a logged in user they see their stuff from the DB, otherwise they see a temporary profile - much like StackOverflow.
How would I go about implementing a security model for this scenario? Can I reuse the existing framework in ASP.NET MVC and use the authorization filters?

GOCR is a common Optical Character Recognition software that can be implemented into almost any programming language. You must convert the image you wish to convert into a PNM file and then proceed to call the executable OCR file. I cannot find any conversion methods for Visual Basic, nor am I quite sure how to send the file to the program and retrieve the text. Has anyone ever worked with GOCR or happen to know anything above?

I am exploring ways of implementing access control permissions in a VB 2008 Windows Application.This is an application for a non-profit where users would log in and depending on their group membership (ie. warehouse, accounting, etc.) some forms would be available while others are not. (eg Warehouse cannot view donor info) Additionally some groups can view information but not alter (add, delete, edit) information.groups who are denied permissions would not be able to open certain windows forms. The question is what is an efficient method of creating this permission structure and how would it be implemented in the application?

I have a question thats been bugging me for quite some time now.Recently, I've created a ButtonRow control which is meant to host several buttons on its surface. These buttons are added through a collection property using the property grid of the VS IDE. The property is tagged with the DesignerSerializationVisibility(DesignerSerializationVisibility.Content attribute.The objects in this collection are serialized to the designer code of the form or usercontrol on which the ButtonRow is placed. Now it all works fine and everything except that I cannot implement a Name property. I'll explain what I mean by this.
If you've ever used the DataGridView control, you'd notice that the columns work in the same way that buttons work for my control ie a serialized collection. However, the DataGridViewColumn has a Name property which can is used as the variable name when the column is serialized into designer code.
Example: If you place a DataGridView on a form and add a column and change its Name to lets say "AGreatColumn" then the designer would serialize the column as such:-
[Code]...
I went as far as using .Net reflector to decompile MS source code to see how they may have achieved this but I could not find the secret. Also notice that the designer serializes my objects using a Dim statement but the DataGridViewColumn uses a Friend Withevents declaration at the bottom of the designer code file(I didnt it included above)

I have decided to use a flood fill algorithm for my application, using this pseudo-code from Wikipedia:Flood-fill (node, target-color, replacement-color):
1. Set Q to the empty queue.
2. If the color of node is not equal to target-color, return.
3. Add node to Q.
4. For each element n of Q:
5. If the color of n is equal to target-color:
6. Set w and e equal to n.
7. Move w to the west until the color of the node to the west of w no longer matches target-color.
8. Move e to the east until the color of the node to the east of e no longer matches target-color.
9. Set the color of nodes between w and e to replacement-color.
10. For each node n between w and e:
11. If the color of the node to the north of n is target-color, add that node to Q.If the color of the node to the south of n is target-color, add that node to Q.
12. Continue looping until Q is exhausted.
13. Return.
I was doing alright, until I hit the "continue looping until Q is exhausted".I don't quite get that.
