The 7.2 system was ! ; compile d without multibyte support. In 7.3, multibyte is always on. I guess it probably doesn't matter much as it's obviously giving only useful encodings, the problem is this (on the 7.2 system):

template1=> select pg_encoding_to_char(45);
pg_encoding_to_char
---------------------
SQL_ASCII
(1 row)

template1=> select pg_encoding_to_char(450);
pg_encoding_to_char
---------------------
SQL_ASCII
(1 row)
0 D

How would the loop know when to give up and exit?

Regards, Dave.

I replace this code in frmdatabase pgadmin2. I don't have this problem.

What is your result if you execute this selection ?

select pg_encoding_to_char(0)

union select pg_encoding_to_char(1)

union select pg_encoding_to_char(2)

union select & nbsp; pg_encoding_to_char(3)

union select pg_encoding_to_char(4)

union select pg_encoding_to_char(5)

union select pg_encoding_to_char(6)

union select pg_encoding_to_char(7)

union select pg_encoding_to_char(8)

union select pg_encoding_to_char(9)

union select pg_encoding_to_char(10)

union select pg_encoding_to_char(11)

union select pg_encoding_to_char(12)

union select pg_encoding_to_char(13)

union select pg_encoding_to_char(14)

union select pg_encoding_to_char(15)

union select pg_encod! ing_to_ch a r(16)

union select pg_encoding_to_char(17)

union select pg_encoding_to_char(18)

union select pg_encoding_to_char(19)

union select pg_encoding_to_char(20)

union select pg_encoding_to_char(21)

My result is :

pg_encoding_to_char
---------------------
ALT
EUC_CN
EUC_JP
EUC_KR
EUC_TW
ISO_8859_5
ISO_8859_6

&n! bsp;LATIN 3
LATIN4
LATIN5
LATIN6
LATIN7
LATIN8
LATIN9
MULE_INTERNAL
&! nbsp;SQL_ A SCII

(22 rows)

The order is not by number encoding.

Hi Frank,



Hmm, that doesn't seem to work here. For any random integervalue of X &nb! sp; & nbsp;that I try in select pg_encoding_to_char(X), I get SQL_ASCII as the result.



This is a problem I would like to fix, though I don't have time myself right now :-(



Regards, Dave.< / DIV>

&! nbsp;&nbs p ;

for reading encodign format current version is:

'Load the Encoding Schemes
cboProperties(0).Text = "SQL_ASCII"
Set objItem = cboProperties(0).ComboItems.Add(, , "SQL_ASCII", "encoding", "encoding")
objItem.Selected = True
&n! bsp; ;
cboProperties(0).ComboItems.Add , , "EUC_JP", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "EUC_CN", "e! ncoding", & nbsp;"encoding"
cboProperties(0).ComboItems.Add , , "EUC_KR", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "EUC_TW", "encoding", "encoding"
cboProperties(0).ComboItems.Add , ! &nb s p;, "UNICODE", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "MULE_INTERNAL", "encoding", "encoding"< BR> ; cboProperties(0).ComboItems.Add , , "LATIN1", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "LATIN2", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "LATIN3", &nb! sp; " encoding", "encoding"
cbo! Propertie s (0).ComboItems.Add , , "LATIN4", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "LATIN5", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "KOI8", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "WIN", "encoding", "encoding"
cboProperties(0).ComboItems.Add , , "ALT", "encoding", "encoding"

this version is a problem to custom encodign into program. For new encodign modify program to add new &n! bsp;encod i gn

For reading automatly encodign usign this code : < /P>

Dim rsSQL As New Recordset
Dim bIsValid As Boolean

&nbs! p; & n bsp;

'Load the Encoding Schemes
bIsValid = True
X = 0
While bIsValid
Set rsSQL = frmMain.svr.Databases("template1").Execute("select pg_encoding_to_char(" & X & ")")
If &n! bsp;rsSQL . Fields(0).Value = "" T! hen b IsValid = False
If bIsValid Then
If X = 0 Then
cboProperties(0).Text = rsSQL.Fields(0).Value
Set objItem = cboProperties (0).Comb o Items.Add(, , rsSQL.Fields(0).Value, &! nbsp;&nbs p ; "encoding", "encoding")
objItem.Selected = True
&nbs! p; & n bsp; Else
cboProperties(0).ComboItems.Add , , rsSQL.Fields(0).Value, "encoding", "encoding"
&n! bsp; ; End If
End If
X = X + 1
Wend
