xBrowse error on ADS (SOLVED!)

[ryugarai27]

Hi Fivewin experts,

I encountered an error using xBrowse with ADS and I am unable to find any solution, hope someone could help me solve the issue. I am having this error:

This happened when issuing the command:
cAlias := oConn:aAlias[MasterDB]
DBSelectArea( cAlias )
xBrowse( cAlias )

I can confirm that the table is not empty by using the lastrec() function, I tested xbrowse using arrays and it seems to work fine. I am using FWH1706 + xHarbour 1.2.3 (Simplex) (Build 20161218) + bcc 7.0

Thanks a lot and more power!

Please let us know the FWH version you are using.

Please also let us know if you are using a modified xbrowse.prg, because the line numbers in the error.log are not matching with the xbrowse source.

Hi Nages,

I am using FWH1706 + xHarbour 1.2.3 Intl. (Simplex) (Build 20161218) + bcc 7.0, I have not modified the original xbrowse.prg that comes with the package source. Here is the link to the xbrowse.prg source file:

https://drive.google.com/open?id=1UQIY8msFCB4dspylDXrgCDbL-eggii6f

Best regards,

[nageswaragunupudi]

Thanks.
I will check with 17.06 sources.
One more clarification please. Do you face this problem with all ADS tables and not with DBFCDX tables? Or only occasionally?

Hi Roderick,

Call me at the office.

Thanks,
Frances

[ryugarai27]

Hi Nages,

This error occurs only using ADS, I have tested the following code and they worked fine:

#include "FiveWin.Ch"
#include "XBrowse.Ch"

REQUEST DBFCDX

function Main()
use customer alias "cust"
xBrowse("cust")

return (nil)

Hi Frances,

I sent you an email on vichezzz.


Thanks,

Hi Nages,

The following code works perfectly on FWH901 (xHarbour build 1.1.0 Intl. (SimpLex) (Rev. 6195) + Borland C++ 5.5.1 (32 bit) ) which uses the Aces32_81.lib and rddads81.lib.

#include "ads.ch"
#include "fivewin.ch"

REQUEST ADS
static hAds, oConn, lOk

function main()
local cPath := "D:\projects\fwh1706\pos6\LocalDB\POS.add"

lOk := .F.
RddRegister("ads",1)
RddSetDefault("Ads")
AdsSetServerType ( 1 ) // local
lOk = ADSConnect60( cPath, 1, "", "",,@hAds)
IF lOk
dbUseArea(.T., "ADS", "MASTER", "_master", .T., .F.)
xBrowse("_master")
ELSE
MsgStop(" Error connecting to tables " )
END

AdsDisconnect( hAds )

return (nil )

But when I tried to compile the source on FWH1706, it compiles without errors but launching the programs produces an error:

I linked the ADS libraray that comes with the package on xharbour_bcc7\lib, files ace32.lib and rddads.lib. Could this be a problem in the ads library? Can I have an ads libraray compatible with FWH1706?

Thanks much and more power!

Hi Nages,

I have removed the ADSKEYNO error by adding the following EXTERN commands:
EXTERN ADSKeyNo
EXTERN ADSKeyCount
EXTERN ADSSetRelKeyPos
EXTERN ADSGetRelKeyPos

but still the error on xbrowse:ldrag persists.

Best regards,

Hi Rao,

Did you manage to check this error?

I have tested the following code on FWH9.01 and it is working fine, but when compiled on FWH1706 the error still persists:

#include "ads.ch"
#include "fivewin.ch"

REQUEST ADS
static hAds, oConn, lOk

function main()
local cPath := "D:\projects\fwh1706\pos6\LocalDB\POS4.add"

EXTERN ADSKeyNo
EXTERN ADSKeyCount
EXTERN ADSSetRelKeyPos
EXTERN ADSGetRelKeyPos

AdsSetFileType( ADS_ADT )

lOk := .F.
RddRegister("Ads", 1)
RddSetDefault("Ads")
AdsSetServerType ( 1 ) // local
lOk = ADSConnect60( cPath, 1, "AdsSys", "",,@hAds)
IF lOk
dbUseArea(.T., "ADS", "MASTER", "_master", .T., .F.)
xBrowse("_master")
ELSE
MsgStop(" Error connecting to tables " )
END

DBCloseAll()
AdsDisconnect( hAds )

return (nil )

Best regards,

Can you please send to my email your copies of

1. ace32.dll
2. adsloc32.dll
3. rddads.lib ( harbour if you are using harbour)
4. ace32.dll

and one free ADT (with adm if necessary) file ( not dictionary bound)

Please send me through https://wetransfer.com/

Note: For version 17.06, two revised builds were published. Hope you downloaded the latest build.

I am unable to understand why are you getting the error.
I am able to browse ADT files with FWH 17.06. This is the test program I tried, which includes simple XBROWSER also.

Hi Rao,

Seems that my FWH 1706 version is not stable, I tried your example and still the error persists. If you could, please send me the link where I can download the stable version of FWH1706.

Many thanks,
ryugarai27

Hi Rao,
