String. as simple as that

Hi,

I am new to VB. I am running VB6 sp3 on Win98.

I have a program querying a db.

When constructing a query, I compose it using String fragments like:

Dim SQL As String

...

SQL = SQL & " And PPC.PNO = SPD.PNO "

When I hit 250 char limit, nothing get's appended anymore.
What do I do wrong?

Thanx,
Cristi

Limit? Maybe i am being dumb, as i have not had to write any SQL satements in a while, but where is the 250 character limit comming from?

You tell me :-(

I just found that after 250 chars nothing gets appended anymore to the string. No matter how many

SQL = SQL & "blah blah"

I add, I can't get past 250 chars limit.

It doesn't have anything to do with SQL, I may try to compose a recipe for strawberrypie this way (appending small amounts of chars at a time) and still cannot pass over 250 chars limit.

I don't understand. This is just a sample of code to build a 500 cahracter string in small portions.

It seems to work.

Code:

---

Private Sub Command4_Click()
    Dim SQL As String
    Dim ictr As Integer
   
    For ictr = 1 To 100
      SQL = SQL & String(5, Chr((200 * Rnd) + 55))
    Next ictr
   
    MsgBox SQL
   
End Sub

You're not using a fixed-length string, are you? (From your example it appeared like you were not.)

In other words, this should not give you a problem:
Dim SQL As String

But this would:
Dim SQL As String * 250

With the String * 250, anything you try to append to it after the 250th character would be lost. I can't think of what else might be causing your problem.

Maybe the String gets right.
I try to see it in the Watch window.
Where I can see max 250 chars of it.
Which makes me mad because I want to run my query by hand to see exactly what are the results.

Is there any way to get this info out from VB6 SP3? I don't want a message box :-(

You mean you want to see the query?

Try

Code:

---

Debug.Print SQL

---

This will print the string held in SQL to the immediate window. Hope this is what you are after.
