I am using access db . In my db one of the table called tblprojects and one of the col called Projects. I want to get the number of Projects , so how can i write the code for getting the number of Projects value? Generally in vb6.0 we can use recordset, by using this put while wend loop.. but in the vb.net how can i get? any how i will send my vb6.0 code plz any one can send code in vb.net.
In vb6.0:

View 1 RepliesI have six textboxes, and upon button press it randomly generates six numbers, one in eact text box e.g. [43] [85] [93] [1] [0] [17]..i create another six textboxes and at the same time allocate these numbers in ascending/descending numbers.I am not looking for any codes whatsoever, as i love the challenge of VB.Net.
View 2 RepliesIm trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
I have a program that allows a user to input numbers from an inputbox and it displays the Total numbers entered, the sum of the numbers entered, and the average of the numbers entered. What I can not seem to find it how to have it display the largest number entered. The code I have so far is,

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.

View 13 RepliesI'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference

View 12 RepliesI've been using it and even saw a method in a MSDN search given that suggests that it should be used but have found that there are defects using it. An example of problem occurring.
Dim db As Double
db = Int(10.12 * 100) / 100
db should be equal to 10.12 but the result you get will be 10.11. In the above example nothing is being truncated. If you added some digits right of the 2 it would give a good result. But if you're using a variable and it sometimes is equal to 10.12 or 9.12 etc. then a problem would occur. Also if 10.12 was replaced with 10.03 you'd get a result of 10.02. 10.04 gives a result of 10.03. 10.2 gives a result of 10.19. I'm now using code such as what is seen below instead of using Int() :
bd = Decimal.Truncate(CDec(10.12 * 100)) / 100
You could declare bd as a Decimal and then you wouldn't have to use CDec(). If I try Int(1012) the result is 1012 but Int(10.12 * 100) will give 1011. Pretty weird in my opinion.

I got the buttons to stop the clock and start the clock. First textbox counts up when i run it if i hit button1 it stops when i hit button2 it starts the counting up again.what I Would Like like is when i put in a number in textbox 2 the clock counts up to that number from where it left off. Like if i have textbox1 = 9 id like it to start at 9 and count up from the last number thats there same goes from couting down but only go 9 numbers up and 8 numbers down from 50 or any number.
Could anyone tell me the logic or the code to do this scenario:I Have 10 numbers (they're in a list or any other), they're all randomized, e.g. {1,4,7,7,5,2,4,1,4,9}.Now there's a code to take all of those 10 numbers and take out paired numbers, they're two ones, two sevens, and three fours. So the program will delete the ones, sevens, and fours, but leaving one four because one is not paired up. Now they're only 4 numbers in the list {5,2,4,9}.
