Calculator help:

Dang, i thought i had this first try, in like 10 lines of code. heres my project.

http://s5.yousendit.com/d.aspx?id=2Q...H2VTHQB5RWJEQ2

The problem is on this line of code, z = x & y & Val(Calc.Caption)

It seems vb wont evaluate it. Any ideas?

You can't use & for anything except strings.

VB Code:

z = x + y + Val(Calc.Caption)

dg, that doesnt make sense with my code at all though.

say x = 5, y = /, Val(Calc.Caption) = 3

youd be writing this.

5 + / 3

that wont work : (

what else could i use

im still learning and so can't help you at the moment.....

i just wanted to knw some parts in your code;.....and design

first of all i wud like to ask is whether u have created a control array for ur digits?

and does the (Index) refer to the index of the control array?

index refers to the caption of whatever i click on, yes its an array

Maybe you could use this:

VB Code:

Option Explicit
 
' Add a reference to Microsoft Script Control 1.0
 
Private Sub Form_Load()
 
Dim x As New ScriptControl
x.Language = "vbScript"
MsgBox Format(x.Eval("(49*48*47*46*45*44)/(1*2*3*4*5*6)"), "standard")
 
End Sub

uhhh...are you sure you posted in the right topic? *** is that? lol

Would this help you more?

VB Code:

Option Explicit
 
' Add a reference to Microsoft Script Control 1.0
 
Private Sub Form_Load()
 
Dim x As New ScriptControl
Dim z%, a%, q$
z = 55
a = 24
q = "*"
x.Language = "vbScript"
MsgBox Format(x.Eval(z & q & a), "standard")
 
End Sub

It prints out 1,320.00, which is 55 x 24 :wave:

heck yes it would. ill check it out

user defined type not defined, also wahts the "standard")

Not entirely true: ampersand is a "shortcut" for LONG data type so
z& = x& + y&
is perfectly valid syntax ...

VAL() isn't the best way of getting numeric value(s) from string ...

That's just for the format command. You can leave it off if you want.
Its the same as Format(x,"#.##") You can use Standard, and a few others.

Where's the error? Try This.

Sorry. I was referring to mathematical evaulations. Also used in Hexidecimal Notation.

Option Explicit
Dim x As Integer, y As String, z As Integer, zz As Integer

Private Sub Cmd_Click(Index As Integer)
x = Calc.Caption
y = Cmd(Index).Caption
End Sub

Private Sub Command1_Click(Index As Integer)
Calc.Caption = Command1(Index).Caption
If Len(x) > 0 Then
z = x & y & Val(Calc.Caption)
Calc.Caption = z
End If
End Sub


please insert as you would :D

I posted the project that you could try. Didn't it work? #12
Add the reference to your project and you can use EVAL to compute the value.

i didnt see it , ill look now

Heres my whole code.

VB Code:

Option Explicit
Dim x As Integer, y As String, z As Integer, zz As Integer
 
Private Sub Cmd_Click(Index As Integer)
    x = Calc.Caption
    y = Cmd(Index).Caption
End Sub
 
Private Sub Command1_Click(Index As Integer)
 Calc.Caption = Command1(Index).Caption
    If Len(x) > 0 Then
   ' z = x & y & Val(Calc.Caption)
        Calc.Caption = (b.Eval(x & y & Calc.Caption))
    End If
End Sub
 
Private Sub Form_Load()
Dim b As New ScriptControl
b.Language = "vbScript"
End Sub

It highlights dim b as new scriptcontrol an says user type not defined or something...it works on your form though, ***? wahts wrong?

Did you add the reference?

' Add a reference to Microsoft Script Control 1.0

Click Project -> References, and check the box next to it.

You can also put the DIM statement in the General Declarations section at the top of your form. Calc.caption needs val(), too

no i didnt add it *slaps himself*

val(Calc.Caption) needs to be changed, too. :wave:

*invalid use of new keyword*
Dim b As New ScriptControl

Post your code.

VB Code:

Option Explicit
Dim x As Integer, y As String, z As Integer, zz As Integer
Dim b As New ScriptControl
 
Private Sub Cmd_Click(Index As Integer)
    x = Calc.Caption
    y = Cmd(Index).Caption
End Sub
 
Private Sub Command1_Click(Index As Integer)
 Calc.Caption = Command1(Index).Caption
    If Len(x) > 0 Then
   ' z = x & y & Val(Calc.Caption)
        Calc.Caption = (b.Eval(x & y & Calc.Caption))
    End If
End Sub
 
Private Sub Form_Load()
b.Language = "vbScript"
End Sub

Click Project -> References, and scroll down to Microsoft Script Controls 6.0 and tick the box. That should do it. I replaces your textboxes (because you didn't post the project with your forms :( )
Here is the code that keeps multiplying the value of the button.

VB Code:

Option Explicit
Dim x As Integer, y As String, z As Integer, zz As Integer
Dim b As New ScriptControl
 
 
Private Sub Command1_Click()
x = 22: y = "*"
Command1.Caption = b.Eval(x & y & Val(Command1.Caption))
End Sub
 
Private Sub Form_Load()
Command1.Caption = 8
b.Language = "vbScript"
End Sub

Zip your project, and upload it as an attachment. I'll fix it for you.
You have a Private Message :wave:

done

I don't know what kind of project you started up, but you also saved the form as module1.bas, which could have helped to mess things up. I tried a lot of different things, before finally deleting everything except the renamed module (to a form) and added it to a new project. It works now, but you can only have single digit numbers. I'll let you work that one out.

This was a major pita. Never seen it before.

lmao really? Well i had an old calculator thing, and i guess i saved it over the old module..I didnt think it worked that way :D

by golly thats funny :D

wait, it works, which is good :thumb:

but i dont see a microsoft scripting control anywhere on your form, or in the properties anywhere!!

wt..?
I thought i had to add that, and i dont get any errors without it here...

its not in components, which you had checked, and had a control in your form.
you need the reference, which isn't a control per se, you just include the references that you want to use in your program. There are two choices from the Project menu Refernces and Components (cntrl-T).
That's the difference.

oh k, cool, thanks dg :thumb:
