NumericUpDown

[Newer_Newbie]

whats with this damn thing. if i have numbers from 0 to 100 as grades how do i set it??

Private Sub numUpDown_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles numUpDown.ValueChanged

End Sub

lets say i wanted a textbox to print out the results of the numericUpDown * something = something

val(texbox.text) = something

?

is that right?

**one more thing whats with the print function damnit?
vb had the picbox.print function and this vb.net crap is all crap

frmMyform.nudGrades.value = 50

To set the grade you don't need to use the change event of the nud.


frmMyForm.tbMyTextBox.text = frmMyform.nudGrades.value

huh

You set the numupdown by using numupdown.value = whatever_your_number_is.

Like numUpDown.value = 80

lets say i wanted a textbox to print out the results of the numericUpDown * something = something

To set the textbox.text value equal to the numUpDown value you do it like

Private Sub numUpDown_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles numUpDown.ValueChanged 
  textbox.text = NumUpDown.value
end sub 

[Newer_Newbie]

ok the textbox print is cool thats what i thought.

but

You set the numupdown by using numupdown.value = whatever_your_number_is.
Like numUpDown.value = 80

end sub

is weird cuz by default i already set it to max num 100 min num 0 so why do i have to set anything inside the code? i mean im pretty good with VB6 but VB .NET is changed up a bit, not to much but its a bit different for me.

this is the code what i doing wrongm i never used the numericupdown function before thats why im going ape **** with it

You need to set the max and mins like: nuUpDown.maximum = 100, etc. It is easier to just use the properties options in the GUI.

You can set the value in the code. So if StudentA got a 85 on the test, you can load the form and then do numUpDown.value = 85 and the slider will start at 85 rather than the default starting spot.

[Newer_Newbie]

the GUI is already set at max = 100, min = 0, increment by 1
all it has is 6 radio buttons and a numericupdown object.
a textbox to display and a cmdbutton to active.

what im doing is if numeric is 90 and no extra credit radio button is click and o day late than its this grade, if this and this is click then its this grade and so on get it?

[Shurijo]

Okay, so on the onChange event of the numUpDown and the onclick event of the radio buttons put a call to another sub

the sub would be like

private sub CalcGrade()

dim i as integer
i = numUpDown.value 'get the grade

if extracredit then ....
i += 5 'add 5 points

if daylate then...
i -= 5 ' minus 5 points

etc.

myTxtBox.text = cstr(i)

end sub

.... etc

(Note: this code is not proper code, just an example of rough code, etc.)

[Newer_Newbie]

ya that would be easy, but i have to use 6 radio buttons.

1 radio button is = 0
radio button 2 is +3
radio button 3 is + 5

radio button 4 is = 0
radio button 5 is - 5
and radio button 6 = -10

i need to have the buttons work when they picked but if they not picked i need them turned off

[Shurijo]

Private Sub numUpDown_ValueChanged(...
  CalcGrade()
end sub 

Private Sub radiobutton1_CheckedChanged(...
  CalcGrade()
end sub 

Private Sub radiobutton2_CheckedChanged(...
  CalcGrade()
end sub 

....

private sub CalcGrade()
Dim i As Integer

'get starting grade
i = numUpDown.value

If (RadioButton1.Checked) Then i += 0
If (RadioButton2.Checked) Then i += 3
If (RadioButton3.Checked) Then i += 5
If (RadioButton4.Checked) Then i += 0
If (RadioButton5.Checked) Then i -= 5
If (RadioButton6.Checked) Then i -= 10

textbox1.text = i

end sub

let me try that out, thanks

[Newer_Newbie]

yo check this out and tell me what im doing wrong cuz i know its something with those damn .checked or autocheck properties

txtTotalScore.Text = totalscore
End If

End Sub

===============================

the numericUpDown Function works perfectly fine now, its havint those radio buttons clicked and turned off when other radio buttons are clicked thats the problem

[Shurijo]

I don't understand what you are doing with those autocheck statements. I thought that autocheck was a boolean (true/false , 0/1, etc.)

Try to remove that code (the autocheck stuff) and put the if then statements in your button click event. Or if you do it like my code above, the grade will automatically be recalculated when you click on a radio button and the grade will be updated on the numupdown change, etc.
