I seem to be having a problem with controls that I am creating as new classes (not UserControls) inheriting from an existing system control. Everything seems ok while I create the control code, through to the compile (which is successful and adds the control to the toolbox) and dragging the control from the toolbox to the GUI surface. However, when I then debug or compile the project, I get a message such

I want to modify this code or replace it. I want to override the the textbox's textchanged event in a user control.

MyBase.OnTextChanged(e)
End Sub

Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

Im still a bit newb to coding in Vb but Im trying to figure out how to make a simple inventory system for my video game. I need it to do a few simple things and Ive never made a inventory system before so im a bit lost on how to approach it.
Functions Needed:
Player has 40 pb that act as the visual inventory or display the item in that slot.

I set up my armor menu to allow drag an drop of the item but again not sure how to even get the inventory system created to finish the armor menu to allow the object to be dragged into its box and remove its self from the player inventory.I think I need to make a array for 39 or 40 in my adventurestorage class. That part Im pretty certain of but how do I set that part up? I have over 200 images that need to act as a item that can be dropped into the inventory.

In the Form1 class there is a server-based timer: when the "elapsed event" fires, then I update the text of a Label1 on the Form2. A very simple code:

I have created a VB.NET project that includes WebBrowser control. The web browser control navigates to html page that embedes a flash movie. Everything works fine except that when I want to exit the fullscreen mode of the video by pressing (Esc) key, it doesn't exit. If I view the html page with any other browser (Internet Explorer, Firefox, ...) it works perfectly. You can download the project from the link below. The files are in the Debug folder.

I've written a pretty good browser in vb.net (it's in the "Share your Project" forum). I now want to give users and other developers the ability to extend/add buttons & functions to it. Can anyone suggest to me a good way of implementing this bearing in mind that I've never tried to do anything like this before? (so basically a way of implementing a plug-in based system. I was planning on these being small snippets of code which my application has the ability to compile.)

What I want to do is basically have a column that ranks the users so if there were 10 people it would rank the person with the highest sales 10 and the second highest 9 and so on. Theres not always going to be 10 employees
I am using a stored procedure along with a sqldatasource to connect to my stored procedure. To get all the data for each agent, then I am using functions like
Dim TotalSales As Decimal = 0.0
Function GetTotalSales(ByVal Price As Decimal) As Decimal
TotalSales += Price
[Code]....
and then some how sort the array list and print the index of the agents sales total?

MSDN: Int32 values are represented in 31 bits, with the thirty-second bit used as a sign bit. Positive values are represented by using sign-and-magnitude representation. Negative values are in two's complement representation. Isn't it true that the representation of positive values using sign-and-magnitude system is identical to the representation of positive values using two's complement system? So shouldn't it have been rewritten as: "Int32 values (regardless of positive or negative) are represented in two's complement representation",

I am in the process of developing an application for one of my clients. I am not going into the details of the applications, but brief facts of the same. The application is divided into two tiers (actually three, but the third tier is the database (SQL SERVER) so that is not included). The top tier (or first tier) is a web application (ASP.NET) where the users shall log into the system and use the application. This web application will also access the Database directly. One important activity the users shall do is uploading excel files with various information to the server. Web Application once the upload is successful shall enter the details in the in Database about the upload along with an ID and save the excel file at a location in the server.The Second tier is a VB.NET Application which will run in the server. The application will connect the database and retrieve the list of excel file uploaded by the web application and start processing one excel file after another based on ID. The processing that will be done is very simple: read the excel file, check for certain parameters, do some calculations and insert the whole details into the database. (say some 100 records per excel file)
The server in which the VB.NET Application (Second tier) runs is hosting a serious of services and application which shall run simultaneously including the Database (SQLSERVER), web server. The Database also host tables and database for various other applications. In order to help in the smooth functioning of the system, it has been decided that the VB.NET shall do the processing activity only when the server is idle (including CPU usage is idle). I have searched the Net and found API to get the system Idle status. But the real question is how to pause the processing activity when the system switch from idle mode and continue when it is again back to idle mode. Please note that I am talking about system being idle because no other application is executing any activity except the VB.NET Application.

I have asked questions about this before but my program has came to cross roads where I require more flexibility in my security procedures.At the moment I generate a specific key based on certain details about the system, and I hash this data to file, which ensures it will only run on this system.
However it has now got to the point where I have a need for providing keys which will carry settings for the program within the key. So that if a customer wants an update its the matter of sending an updated key, which will allow certain areas of the program to be unlocked/locked.Obviously I can no longer use the hash, as it can't be decrypted. I am looking to use key encryption system, which will allow to encrypt data within a license key. But obviously it brings the problem of where to store Crypt & decrypt key within the program.

I am trying to create a textbox that will display the total duration of all video files in a listbox. I am not using the windows media player in the project, I just want to show total duration of the listbox items. I have tried looking for snippets because I'm new to programming and I have also tried my luck at creating a class with no success. If anyone could show me some sample code or tell me what it will take to accomplish my goal it would be greatly apperciated. I am coding with Visual Basic 2010 express.

I'm kinda new to this. Done it a bit a while back, completed a simple conversation program, and started a text game..but decided to take it back up and make a new interaction fiction game with videos.. the thing I'm having a problem with right now is the windows media player control. I make my first intro movie play by placing it's location in the URL property...I'm wondering how you would code it to play the second intro video I have once that one comes to an end.. I may just put the two videos together to make this easier.
