is it possible to pass variables from a textbox in visual basic?

is it possible to pass variables from a textbox in visual basic?

i am trying to pass a variable from a textbox. eg this is what is contained in a textbox


Hallo " & !Name & ", your current balance is " & !amount & ". please pay this amount to avoid disconnection!!! Customer Service.

the variables contained in the text box are !name and !amount

the app should be able to tell me what is contained in the field amount and name.

Pass the variables from a textbox that is *where* exactly?

If it's your form, it is simple enough to do this...it's fundamental programming :-P

Yes from my form. can u show me how to do this. below is the code am using but it doesnt pull the variables. it just returns the same string that is contained in the textbox

VB Code:

Set SQLINTERGRATION = New ADODB.Recordset
    Dim sTemp As String
    
    If txtsql.Text = "" Then
        MsgBox "Please specify the sql string to be executed", vbInformation, "Error"
        Exit Sub
    End If
    
    SQLINTERGRATION.Open "" & txtsql.Text & "", gConnection, adOpenDynamic, adLockOptimistic
    Set DGINtergartion.DataSource = SQLINTERGRATION
    With SQLINTERGRATION
        Do While .EOF = False
            sTemp = txtsqlmessage
            MsgBox sTemp
        '...
          .MoveNext
        Loop
    End With

The textbox has a .Text property. Call that.

BTW, ! is not allowed in variable or control names.

What context does this apply to?
Where do the name and amount come from? A database?

How do the variables get into the textbox? What is your query for that? (I see what you have in Post #3, but that doesn't look like it is doing anything.)

name and amount are coming from a database.

This is what i am trying to achieve. a user types a custom message on a textbox where he has included the variables. My app then does a loop through the recordset a creates a customized message fro each record.

Ok. Then what is contained in txtSQL.Text?

So the variables are taken from the database...put into a textbox...

Now I am guessing that what you want is for the text in text1 (for instance) which says "Hallo !name, your current balance is !amount. please pay this amount to avoid disconnection!!! Customer Service." to be changed to replace !amount and "!name" with the actual name and amount.

If so, try "text2 = replace(text1,"!name",txtName)" and "text2 = replace(text2,"!amount",txtAmount)

Edit: Hack, I am guessing it's "Hallo " & !Name & ", your current balance is " & !amount & ". please pay this amount to avoid disconnection!!! Customer Service."

a user will type them in with a customised message. the query is also input by the user since my app is able to connect to any database. the user types in a query and the results are then put in a datagrid.

a message is then typed on a textbox including the variables. its kind of a mail merge..

the variables are not put into a text box. they are put into a datagrid and the user types the column heading preceeded by a ! to denote the variable. hope am not confusing you

I think that *basically* the function you need is replace...I describe how to use it above, but it's as simple as replace=(STRING,FINDTHIS,REPLACEWITHTHIS)

So if you had debug.print replace("abcdefghijk","abc,"ABC") it would return "ABCdefghijk"...so it replaces "abc" with "ABC"...sound as simple as ABC to you now? :-)

leaving it for the user to type the query in sounds like an error waiting to happen

i only allow SELECT statements to be typed. Inserts Drops alters are disabled. n way only an admin will be using the system.

below is a screenshot of the app.

hope this will be more clearer on the predicament i am facing?

So you need to take a string message such as "Hello !name, your current balance is !amount", which you get from the user via a textbox, and replace the ![variable] parts with the value of the column with the same name in the datagrid, and do that for each row in the datagrid, creating many results?

Thats exactly what i want to achieve. is it possible or is there a simpler way to do this.

Pseudo-code - since I haven't used VB6 in a while and I never used the DataGrid...

VB Code:

Dim strResult As String
for each row in the data grid
    for each column in the row
        replace "!" & column name in strResult with value from column
    next
    'do something with strResult which now has all the values from current row
next
