Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
The end result is baffling me here are 2 examples when I debug
Mine: 640.1 * 49 = 31364.9
Debugger: 640.1 * 49 = 31360 ( not right needs to show the correct decimal )
Mine: .775 * 3 = 2.325
Debugger: .775 * 3 = 2.325 ( shows it perfectly???)

I would like the "Percent" result to come out as 37.50%
correct syntax to format decimals. I want 2 decimal places even if the result is an even number i.e. I want 40 to show as 40.00 and 40.6666667 to show as 40.67.
View 8 RepliesI'm very new to VB 2008 and I need to round the result of a calculation to three decimal places after using a button click to complete the calculation. I've tried the Round function to no avail.
View 16 RepliesI have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
How can i format a decimal result to a string without the .00 suffix?
View 7 RepliesI'm trying to do this division and the result to be displayed on a eight decimal number.
Dim r1 As Integer
Dim r2 As Double
r1 = Val(TextBox16.Text)
r2 = r1 / 60
TextBox18.Text = FormatNumber(r2, 8)
The value or R1 on this case is 273.4 but it varies according with the result obtained so I can not allocate a constant number to r1. The problem is the result that I am getting is 4,55000000 instead of 4.5566666

i have uploaded 3 pics shows 3 diff forms.
1. BaseForm.( Includes 2 button, Buttons Text "Form1" and "Form2")
2. Form1. (Just inherited BaseForm)
3. Form2. (Just inherited BaseForm)
If the Button Form1 clicked then it shows Form1 disable Form1 button. and Hide BaseForm. same action for Button Form1.
When I click the Right Top Cross button then the Background BaseForm Still running. I want to close all form If I click cross.
im working on a little project and i need my form1 to basically spam itself in random locations...
View 5 RepliesI have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.
View 3 Replies1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:
Variable 123.34D ----> textBox 123,34 or 123.34 -----> variable 123.34D
I have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.

I am using the Math.Exp function in a calculation, and the result essentially is Infinity / 1 + Infinity, which is 1 statistically, but it is showing as "NaN" (not a number). Is there a way to calculate/show the result of this as 1 (besides just testing for NaN and explicitly setting it as 1?) [code] X is a number larger than 709.782712893 in order to get the NaN result.

View 6 RepliesToday I installed VB 2008 express and having some older experience with VB at school I tried to translate some algorithm functions to VB. I came across these lines which are very simple.I had one textbox and wanted to show The result is x when i click the button. so, here is the part of the program.
Dim x As Integer
Dim y As Integer
Dim w As Integer

Because I write on paper in pseudo, "The result is", x would be correct and would show The result is x but instead, VB finds error. Does , indicate space here or does it recognise it as something else?
