Here is a sample connection string for Ms Access with a password... see the variable xString.

Rick Lipkin

Code: Select all  Expand view

//-- get location of .exe assuming the .mdb is in the same folder //

cFILE := GetModuleFileName( GetInstance() )
aDIR  := DIRECTORY( cFILE )

// where .exe started from is default directory //

nSTART := RAT( "\", cFILE )
cDEFA  := SUBSTR(cFILE,1,nSTART-1)

xPROVIDER := "Microsoft.Jet.OLEDB.4.0"
xSOURCE   := cDEFA+"\YourTable.mdb"
xPASSWORD := "xxxxxx"

xSTRING := 'Provider='+xPROVIDER+';Data Source='+xSOURCE+';Jet OLEDB:Database Password='+xPASSWORD

From FWH 13.06 onwards we can open access (mdb or accdb) files with password using:

oCn := FW_OpenAdoConnection( <cmdbfilename>, <cpassword> )

The function internally builds the proper connection string.

Mr. Nages,

In source\function\adofuncions.prg this is what I have:


function Fw_OpenAdoConnection( cConnStr, lShowError )


Nothing about password.

Mr Lucas

Regret my inaccuracy in the syntax.
The correct syntax is:
oCn := FW_OpenAdoConnection( "<cmdbfilename>,<cpassword>" )

Example:
Create a password protected mdb file with:
FW_CreateMDB( "c:\mydata\tutor05.mdb", "mypassword" )

and open it with
oCn := FW_OpenAdoConnection( "c:\mydata\tutor05.mdb,mypassword" )
OR
oCn := FW_OpenAdoConnection( { "c:\mydata\tutor05.mdb", "mypassword" } )

thanks for answer

but if I use
cPath := cFilePath( ExeName() )
xSOURCE := cPATH+"waga.mdb"
xPASSWORD := "123456"

oCon := FW_OpenAdoConnection( xSOURCE,xPASSWORD)

cSQL:="select idklienta, nazwa, adres, nip from Klienci"
oRes := FW_OpenRecordSet( oCon, cSQL )

the function FW_OpenRecordSet( oCon, cSQL ) retrun error openning table Klienci

best regards

Please use:
oCon := FW_OpenAdoConnection( { xSOURCE, xPASSWORD } )

or

oCon := FW_OpenAdoConnection( xSOURCE + "," + xPASSWORD)

[kajot]

if I used function
oCon := FW_OpenAdoConnection( xSOURCE + "," + xPASSWORD)

the database opened good, but the function FW_OpenRecordSet can't open the table

cSQL:="select idklienta, nazwa, adres, nip from Klienci"
oRes := FW_OpenRecordSet( oCon, cSQL )

It is working here for me.
Example code:

Code: Select all  Expand view

function TestPW

   local oCn, oRs
   local cmdb := "tutorpw.mdb"
   local pwd  := "12345"

   if ! File( cmdb )
      if ! FW_CreateMDB( cmdb, pwd )
         ? "MDB Create Fail"
         return nil
      endif
   endif

   oCn   := FW_OpenAdoConnection( cmdb + ","  pwd )
   if oCn == nil
      ? "Connect fail"
      return nil
   endif

   FW_AdoImportFromDBF( oCn,  "c:\fwh\samples\CUSTOMER.DBF" )

   xbrowser fw_adotables( oCn )

   oRs := FW_OpenRecordSet( oCn, "CUSTOMER" )
   ? oRs:State

   xbrowser oRs
   oRs:Close()
   oCn:Close()

return nil

thanks a lot

I can't check up our program, because I have FWH v. 12.06

so I got many error

xLINK: error: Unresolved external symbol '_HB_FUN_FW_CREATEMDB referenced from (t.obj)'.

xLINK: error: Unresolved external symbol '_HB_FUN_FW_ADOIMPORTFROMDBF referenced from (t.obj)'.

xLINK: error: Unresolved external symbol '_HB_FUN_FW_ADOTABLES referenced from (t.obj)'.

You can try to modify the function FW_AdoConnectionString as well

Code: Select all  Expand view

function FW_AdoConnectionString( cConnSpec, nDb )

.../...

      elseif cExt $ "mdb,accdb,bds"
         cRDBMS      := "MSACCESS"

.../...
