<div id="ygrps-yiv-1077502754">Has anyone achieved a DSNLESS connection to Vantage 4 using VBA or <br/>
VB?  If so, could you post the connection string you used?  I get the <br/>
Progress Login box (to which I simply hit OK), then I get Run-time <br/>
error 3000, Reserved error -7778.  Here is the code I&#39;m attempting to <br/>
use, which fails:<br/>
<br/>
tdf.Connect = &quot;ODBC;DRIVER={MERANT 3.70 32-BIT <br/>
PROGRESS};DB=vantage;OIDP=TCP;OIDS=odbc40;OIDH=vantage;DBAM=Direct;DBP<br/>
R=TCP;DBPA=d:&#92;epicor&#92;vantage&#92;db&#92;;ASC=0;SR=1;GST=0;UID=;&quot;</div>
