I think for you my problem is very simple..I have done the same program in console mode without problem, now i try into windows form...
I generate by random 2 number A&B I multiply them and I will compare it with the result in my textbox3
if it the same as the computer has calculated il will show you congratulation, however i will say try again
I have a problem to calculate the sum, A&B are well generated but nothing in Calc Result
When Calc was working when I write nothing in the textbox3 and i click on Verify it show the msgbox congratulation.I'm looking just for this step, I've fixed the other issues And another things When It's right I would like to random another number for A&B after closing the msgbox, how can I processd ?

I have made a vb.net application which has 63 forms. On each form label2 should contain the username using the application. The first form displayed to the user is the login form. When the user clicks the login button on this form the user name in all newly opened windows should appear inside label2. How can I do this?
View 3 RepliesDim result as single = 0
result = CType("8.01", Single) * 100 ' result=801.0 as expected
result = CType("8.02", Single) * 100 ' result=802.000061 --- not expected
Further to the above
result = 8.02 * 100 ' result = 802.0 as expected
I am very new VB .NET and just starting If statements. My problem is: Write an If statement that determines whether the variable CurrentBalance is greater then 1000.01. If it is, multiply the variable CurrentBalance by 1.005. Otherwise, multiply CurrentBalance by 1.007.So far I have
Sub Main()
Dim currentBalance As Boolean
System.Console.WriteLine("Enter Current Balance: " & currentBalance)
If CDbl(currentBalance) > 1000.01 Then

I really don't even know if thats how I should be starting. Not sure what to put after the first Then on how to make it multiply currentBalance by 100.5.
This is part of a calculator program. I first part I sort by num and sign using a multitude of commandbuttons with no parenthesis.This program below is part of the second part. I have three more subroutines for /, +,- respectively.The + and - work correctly but * and / do not.I think it is in the line: numop(m) = g * h Is there something I am doing wrong wth the syntax in multiplication?
Public str, sign(100), numstr(100) As String
Public num1lock(100), m, n As Integer
Public ans, num(100), numop(100), g, h As Long

I have an assignment to make a multiplication table using loops. The idea is to make this: If the user enters 3 this is the result he gets:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
if the user enters 5, this is te result:
0 1 2 3 4 5
1 1 2 3 4 5
2 2 4 6 8 10
3 3 6 9 12 15
4 4 8 12 16 20
5 5 10 15 20 25

I'm new to VB and programming in general and have not had too much trouble however i cannot figure this problem out and i've been working on it for a week. basically i have to create a program that calculates the mass of someone on another planet with the conversion numbers as constant, an input box for the user's mass, using select case format and output to a label including the name of planet ie "Your mass on &strPlantet is x" so what happens is my intWeight variable becomes zero and the lblResult is Zero. (i have not added the all the code for the label output) oh yeah i must also use a try/catch structure to prevent non numeric data from being input.[code]

Simple Calculator multiplication and division Trying to make a simple calculator. My program inputs numbers and arithmetic operations thru commandbuttons. The numbers, num(n-+1), are odd and the operations, op(n), are even. The code is based on the even op string. Every time a op occurs it is stored in numop(n) to be accessed later. I have all the other operations in sequential order: "*"," "/, "+" and "-". The other similar For-Next loop are the same just interchange the two * for /, +and -. The "+" and "-" work fine in this configuration.
My problem is the multiplication and division does not occur. The numbers and operations line up. The numop(m)=g*h should yield numop(m)=num(1)*num(3). Is there some sort of code to be inserted to accomplish these multiplication and division operations?

View 4 RepliesMakes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I want to open an Access database and I want to multiply 2 fields between each other. I am a newbie and till now I only have found the way to open the access database and create my Recordsets. So, for example, if I have table Mytbl that is a recordset with 4 fields (columns) and I would like to multiply column 3 with column 4 and put the results in a new Recordset, do I have to do it by multiplying each and every record
View 4 RepliesI have some combo boxes that basically set labels and scale multiplication factors for an XY grid. The combo boxes themselves work as they should. Two adjust scale levels of the XY grid (label and multiplication factors) the other changes the Y axis units (Imperial/Metric). The issue comes when I try to replot old data... I have the data in the array and have confirmed it is accurate...but...
When I apply the appropriate value to combobox.selectedindex and then call the Sub that actually makes the scale changes, the selected index reverts to -1. Small Example.... (note consider all variables as public and all routines in a single class - ignore spelling - this is a quick subset recreation not a copy).
Private Sub ReloadGraph()
combobox1.selectedindex = LengthScale(GraphNumber)
Call LengthLabels()
PlotUnits = Units(GraphNumber)
Call UnitsSet()
[Code] .....
OK - so I did add some code..... I did not actually run this code, but this is essentially a snapshot of what fails....when I step through line by line, the selectedindex changes to -1 as soon as I step to the second line of the second 2 Subs BEFORE it processes the second line (i.e. always after I step off Private Sub xxx() ). Again, both UnitSet and LengthLabels work OK separately when called, it is ONLY when I set the selectedindex from a variable (and again, it DOES set OK) and then call these routines that the selectedindex goes to -1. I have read a bunch of stuff relating to selectedindex and selectedvalue resetting IF one or the other is blank, but I have tried setting both in testing and this fails too!!

View 8 RepliesI have made an countdown app that is working in a normal way (added picture of it). Now when I select a number in the numeric box and click start, it starts to count down from that many minutes, but what I want is the number I put in the box *3. So if I put in 3 (points) the counter will count down 9 minutes. If it is possible I want a counter at the bottom every 3 minutes the value of the 000 at the bottom of the image multiply by 1 (+1 for every 3 mins timer1 runs).

You will need to make use of the RichTextBox, along with concatenation to make the output format correctly within the box.When you have created the working program, document it properly by printing out and annotating the code to explain how it works."

View 6 RepliesIs it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
