adding arrays

hello guys

i have a quick question

how can i add an array to each other ................ for example

i created an array like ...... price(100)

and it collect the prices which is added fron text box

and i want to add them to each other and asign the total to a variable called ......total and print it in a form


thanks

any one has an idea

I suppose you could iterate through the array with a simple loop.

wizbang

how lets say that i have a hundred array

price (100)

how to get the total of them

i did this:


for counter = 0 to 100

total = price(counter) + price (counter)

next counter

but this gave me the wrong summtion

any one has more ideas

do you want a single total for the 101 prices?
then simply:

Code:

---

Dim Total as double
Dim Counter as Long
For Counter =lbound(price) to ubound(price)
  Total= Total+price(Counter)
Next
msgbox format(Total,"@,@@@,@00.00")

thanks man it is working fine

now i have anthor quetion

how can i set them prices and the total to zero..... i mena by this to clear the variable price(counter) and set it to zero


thanks again

the total:

Code:

---

Total=0

---

A single cell:

Code:

---

price(55)=0

---

the whole array (if it was a fixed length one, like in:
Dim Price(100) as Double

Code:

---

Erase price

---

If it is not a fixed length array (or if it is not
a numeric one and you want a zero inside each cell)
then:

Code:

---

Dim Counter as long
for Counter=lBound(Price) to Ubound(Price)
    Price(Counter)=0
next

---

thanks cimperiali

it worked

i have some more quetions ;)

now what i am buliding is a program which connect to database that is local to my hard drive using ado like this


Set adoCon = New ADODB.Connection
Set adoRecordset = New ADODB.Recordset
connectString = "Provider = Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=f:database\sample.mdb"


adoCon.Open connectString
adoRecordset.Open "product", adoCon

so now if i want to compile my program and use it as an exe, what should ido

note this"Data Source=f:database\sample.mdb" .....how can i use it universally

thanks

Many ways.
You could have an ini file (or a registry key) where to put the path of db.
Or, more easily, you could have the db in same folder of your exe and code
like the following (it will work also in develope if you open your project by
doubleclicking on it via resource explorer. It will not work fine if you open Vb
ide and then open the last opened project...) :

Code:

---

connectString = "Provider = Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & AddSlash(App.Path) & "sample.mdb"

---

where addSlash is a function like the following:

Code:

---

Public Function AddSlash(ByVal sPath As String) As String
    sPath = Trim(sPath)
    If Len(sPath) > 0 Then
        If Right$(sPath, 1) <> "/" Then
            If Right$(sPath, 1) <> "\" Then
                sPath = sPath & "\"
            End If
        End If
        AddSlash = sPath
    End If
End Function

---

By the way: you could put the db in a subfolder. Ie:

Code:

---

connectString = "Provider = Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & AddSlash(App.Path) & "DataBase\sample.mdb"
