I'm making a rating system for people to rate things in a listbox. I've setup so the stars get saved using my.settings, but how would I make it so it gets stored into a database, and it checks to see if they already rated.

How can I speed up a process? I see I should use timegettime, gettickcount, and queryperformance counter, but I have no clue where to start.
I guess you can call it Frame Rate or Refresh Rate of a process?

I need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).
Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.
The summary menu item displays a message box that holds total sales, total commission, and total pay for all salesperson. Display the number with two decimal places and dollar signs.
the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.
The Color and Font menu items should change the color and font of the information displayed in the total pay text box. Use a message box to display the program name and your name as programmer for the about option on the Help menu.
[code...]
So the issue is when I push calculate and summary, the total sales comes up, but not the total commission or total pay. Also, the color only changes to blue and that is it. I am not sure how to get the color or the font menu choices to be able to be choosen by the user. Is that possibile?

I'm using Visual Studio 2010 and Excel 2007. I'm having difficulty figuring out how to convert an office excel project into a vb.net project. I wanted to take the ugly windows 98 style buttons I currently have in my spreadsheet and replace them with controls on a new tab on the ribbon. I can make it that far, but I didn't anticipate the large gap between languages.
The code below is supposed to take a bunch of information from a windows form and insert it into a new row on sheet12, sort the table of info, and name the range. Right now visual studio show no errors until I actually try to run the code at which point it says "Object reference not set to an instance of an object." regarding the code "oSheet.Rows("1:1").Copy()" I don't think I understand declaring my variables in vb.net.

In my tic tac toe game I'd like there to be three different levels; easy, medium, and impossible. There are 2 forms; the difficulty level form and the main game form. When the game first starts the user will be prompted with the difficulty level form which contains 3 radio buttons; easy, medium, and impossible.
I've coded three different functions based on the difficulty level; easyMove(), medMove(), and impMove(). These have all been coded in the main game form. How could I run the respective function based on the radio button that was selected in the previous difficulty level form?
If it was on the same form it wouldn't be a problem but because it is on a different form I'm unsure of how to do this.

Okay, i've tried httpwebrequest, webclient, and a couple of others methods; using the headers parameter of each to set headers and then either opening a response stream or simply setting the system.net.webclient method to download a response into a string. Put simply, how do I make a simple GET request with a few headers and read the data back! I am very, very stuck in a hole right now..

I am currently developing in Visual Studio 2008 (Visual Basic) and I have no problem reading, editing, saving, etc. to a 2007 Access database that is stored locally using the following code:

I'm not sure if this is really a VB IDE issue, or a more general VS10 issue, but I couldn't find any other relevant category to post in, so here goes!I have several VB projects which I want to use in the same solution in Visual Studio 10. I created a project (& corresponding solution) which will reference them and added the existing projects by right clicking the solution in solution explorer choosing 'Add->Existing Project'. Then I went to the containing project's Properties window and added references to the existing projects, so they could be used by the project.

I'm having a strange difficulty. Here is the order of events:User presses button on form1 New Form object is created for from 2 New form object '.show' command is fired Form 2 opens correctly In the Load Event of Form 2, the form attempts to do various things in a try, catch, finally clause On catch, I close form2 down '.close' as it cannot be used as something has gone wrong with the execution However, my problem is this. It is acceptable for things to go wrong on the from 2 load event which is why I have implemented the try - catch functionality. However, when I close the form2 down as a result of the problem, a real error ocurrs 'Cannot access a disposed object' and the VB IDE refers me to Form1's '.show' event for Form2.
It is almost as if the form hasn't fully 'shown' before I am closing it down. Does anyone have any idea what the problem is here? Do I need to close down Form2 ourside of it's Load event handler so that Form1 thinks it has loaded correctly?

I'm attempting to import an excel spreadsheet into a dataset. The spreadsheet is selected by the user by browsing for a file. I can get it to work properly only if I know the exact sheet name, but it varies from sheet to sheet. I need to tell it to always use the first sheet in the workbook.

Recently I started a project with the goal being to have text that was inputted into a textbox stored within a three dimensional jagged array. The idea is that every time a button is pressed, whatever text that is inputted into the textbox is split into separate elements, where each word occupies its own element in the array. So for example, if a poem were entered into the textbox and the button clicked, each word of the poem would be assigned to a discrete element in the vertical dimension, and each line of the poem assigned an element in the horizontal dimension. After the text is stored into the 3D jagged array, the text should be cleared from the textbox and a counter should then ensure that on the next button press, the new text inputted into the textbox is stored in a discrete element of the array. Below is the code I have written so far, but I know that I am far from having anything might accomplish what I have just described.

What would be the best way to make a Windows .NET application be the only program that can be used on a computer? I have come across timers or events to switch windows back to a window with matching text and some api32 calls to make a form top most.
Is it possible to make an application like the windows lock screen where nothing can be done except that what is on screen? I want to block users from doing other things and only let administrators get to the desktop.

I am making a program that is very simple, but I'm have problems with it. It runs like this:Theres a textbox and you enter in any amount you want.Next to that there are three radio buttons, deposit, check and service charge.If you enter in 100 in the transaction text box, and check the deposit radio button, and hit "Calculate" it will display 100 (in a total display box); hit calculate again, it will display 200, then 300, etc..Now lets say you keep 100 in the text box, but you check either "service charge" or "check" and hit calculate then it will MINUS the amount in your total display box. So for example if you had 300 in the total display box, and 100 in the transaction box and you checked "Service Charge" and hit calculate it would display 200 in the total display box, hit calculate again, and it shows 100.. etc..

I am making a program in vb.net (visual basic) that has two forms. I have one as a sort of "main" base which will be behind everything. Then I have another additional form which is suppose to go on top of the "main" form. Well I get this to work when I show both of the forms, but I want the smaller (additional) form to be centered onto the main form. If you want an easier sense of it, its a small box in a big box. (all centered and aligned). Does anyone know how to do this?

I have an exe with certain variables that need to be changed for each "make" of the program so that each one is customised, but what I need is to create a program that can edit these variables and generate a new exe, or something that can take the source files from my exe and edit the variables then recompile it. Now I don't want to hear "why not just do them by hand", if I wanted that I wouldn't be asking how to do this, I just need this because I need to create 1000's of these custom exes, and I figured that if I could make a program that can do this (edit the variables and compile new exe) then that would make it easy on me since the variables I need to change go in an order from 1 - 1000. I also need it to work on a regular pc not one with all the special VB plugins and stuff, it needs to be able to work on a fresh install of win xp.

I have the following Query:
SELECT *

WHERE OvenLoadId IN (
SELECT OvenLoadId

The idea of the query is that I want to specify an OrderId, and I want all Oven Loads that have items from that order in them, as well as ALL OTHER ITEMS in those loads, even though they could be from other orders.The query works as expected, but I'm not able to use it for my Crystal Report I've written it for.I have put this query into a User Defined Function, however I'm unable to use a call to that function as a table source in my Crystal Report.

I have searched lots of way to make a 30 day trial limit of my program. They say "Use -Settings- in visual basic application for your variables" to save the information about user (like : registered or not registered or when the program expire). (You can see the 'Settings' when you double-click on "my project" in "solution explorer") Does the data which we use with "settings" saved in our program or somewhere in the computer?
