adding and subtracting 2

[k7k1z1]

hello, I'm VERY new to visual basic and am having problems
trying to get my .exe project to add numbers together.This is what I write.

lbltotal.Caption = txt1.Text + txt2.Text + txt3.Text
cmdjhclose.Setfocus

Though it won't actually give me the option to put ".Text"
it only gives the options to put "count", "item" , "lbound" ,
and "ubound". If anyone could give me some advice I would appriciate it, thanks.

Create form with three text boxes(text1,text2,text3), one CommandButton(cmdAdd) and one label(label1). Double click on the button and add the following code.

Private Sub cmdAdd_Click()

Dim x1, x2, x3, sum As Single

x1 = Val(Text1.Text)
x2 = Val(Text2.Text)
x3 = Val(Text3.Text)
sum = x1 + x2 + x3
Label1 = sum



Next buy a VB Book..
End Sub

From the sounds of it, you have a control array. At least that's when the bounding and item properties are present.

If your sure the names are correct remove the value from the index property in the design. You can also add the index to your code like [tt]txt1(0).Text[/tt]. Make sure the indexes in your code match up with those in your design.

Other than that, the Text property of a control is a string. With strings addition causes concatonation. To treat the control values as numbers use the VAL function as instructed above.

The VAL function only recognizes the "." as a valid decimal separator. For some international applications this can bite you. The CDbl or CSng functions avoid this pitfall. Dan Grogan

Without common sense you ain't gonna have nothing.

There are other issues surrounding VAL which would deter me fromn using it. Dan is right; use explicit conversion functions instead.

OK thanks for the info, I'll give the other
functions a try.
