Also I need this as a robust solution so changing CLSIDs is not working.
Also removing permission with FileSystemAccessRule with AccessControlType.Deny also not working for me. Because that only work on NTFS and also if it is worked then user can right click the folder and remove deny AccessControlType.
let's say I create a basic windows form with 100 textboxes, and create a variable that starts at 0, and counts up to 100. How could I pseudo-effortlessly have, for example, textbox7, when the variable is at 7, display a piece of text, instead of writing 100 lines of code such as
if vara = 7 then textbox7.text = "hello"
is there a way to utilize something in the nature of LINQ, where you could somehow say,
if vara = 7 then textbox & varA & .text = "hello"
this is just an example, I know it will not work, after paying a small bit of attention to the likeliness and possibility.....
I have a small program that checks webpages for certain strings. I am using VB express 2010 .net version 4.I have the list of URLs in a listview, and loop through all the urls, perform a webrequest, check if the source contains certain strings and then add a subitem to the current listview with text to indicate the result I am attempting to speed the application up using a parallel.for loop, but this causes a cross threading exception.This is the code for single threaded:
For i As Integer = 0 to lvUrls.Items.Count - 1
Dim lv As ListViewItem = lvUrls.Items(i)
lv.UseItemStyleForSubItems = False

Worked fine except that it took approx 5 minutes to load. Converted it to a wmv file (cutting it down to 300 MB) and it started playing instantly while it download. Unfortunately there are some computers that will not play it for some reason. It will load and the timer starts up as if the video is playing but there is just a black screen. I ran some tests and determined that it's not a browser issue.
How can I upload a video that instantly plays on all computers?

I want to do a project in vb.net 2008 using database from MS Access 2007. I have to go from the main menu to the other forms, in each form I have to select one or more items, each item has a price (should be taken from the database *.accdb), then I have to return to the main menu, click the cost button to find the total cost of these items.
1. Where I have to write the code to access my database, in the main menu or in each form individually? and how to write it? I used the code found at:
http:[url]......
but after DEBUGging told me that it cannot see "Table1"?
2. When I am in one of the forms, do I have to "save" my selections, and how?
3. How do I exit from any of the forms to give me the total price to the step, form, I have reached?
4. The total cost should appear in a separate form (screen) at the same time should be saved?
I am trying to use if statements to add the prices of a cruises special packages together. I am using check boxes for the packages, so any, from none to all 3 are able to be checked. The packages available are VIP, excursion and restaurant. The price will also depend on the cruise length (7 or 10 day). I am wondering on which format to use, and if I even need to use if statements, how to make this statement true,

I am trying to put together a simple form with prices assigned to Radio buttons and check boxes.
I started by creating a simple form with four Windows Form control, two check boxes and two radio buttons, there is also a NumberUpDown Control for quantity but I have not added that yet.
Basically the user make selections, the price is calculated with total and subtotal and displayed on a label.
I am trying to start as basic as possible then work my way up to more complex calculations as I progress.

View 11 RepliesSweet candy store currently has a special offering of heart shaped candy. It comes in two sizes: small and large. The company sells the large one for $29.50 and the small for $16.25.Design an application to calculate how much a costumer owes. When the user clicks the "Calculate" button, the program gets the number of large and small chocolate hearts ordered from the textboxes, calculates and displays the extended price for each type of the chocolate in a label. The program also calculates the weight of the chocolate to determine the shipping cost, displays the total weight, the shipping cost and the final total due. The large chocolate weighs 4 pounds 10 ounces, and the small one weighs 2 pounds 14 ounces. Shipping cost is 35 cents per pound and 3 cents for each additional ounce. Display all dollar amounts except the final total due with 2 decimal places. Display the FINAL TOTAL DUE with a leading dollar sign and 2 decimal places. Be sure to also include a CLEAR button that will remove all inputs/outputs from the form, and an EXIT button. Define the CALCULATE button as the accept button and the EXIT button as the cancel button.

Im trying to make it so I can input a number for a percentage, multiply that with my current array prices, and display the total in the listbox. I have a few theories on why it isnt working but cant pinpoint which one to use, I'm at a basic level to this and still learning the process. Im also pretty sure I dont have everything I need on here yet.

This is not a problem, as my code works correctly, but a question of aesthetics.

I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.

But I my opinion this function is available in VB.Net. Is there an easy way in VB.Net to calculate the next quarter.
