Set string lengths

in vb6:



Dim textSend As String * 256
Dim textRecieve As String * 256



Call FT_Write(myDongleHandle, textSend, 256, lngBytesWritten)



How do i accomplish this in Jabaco. Need to set the string lengths to send to a hardware device, becuase the dll requires a certian length string even if it is empty.



also in calling a dll:



Call FT_Purge(myDongleHandle, 1 Or &O2)



the &02 is hex, how do you do this in jabaco.



Thanks

Hi,
hex constants have to be entered via a workaround (for the time being). See here. "1 or 2" will yield "3". The "or" is implemented as bitwise or as it is the case in VB6.

Strings of a specific length can be defined as follows:

Jabaco Source

 
1
2
3
4
5
6
7

Option Explicit

Public Sub Command1_Click()
   Dim s As String = Space(255)
   
   Debug.Print Len(s)
End Sub


Calling DLLs is a bit tricky in Jabaco. Dig this forum for WINAPI to get to know details.

Greetings!
