php.exe - Application Error The instruction at "0x00c4dff2" referenced memory at "0x00c4dff2". The memory could not be "read". This is happening intermitantly for many of my pages. Sometimes hitting refresh will fix the problem, sometimes it will cause another error. I am running php 4.0.5 as a cgi under IIS 5 on Win2000. My script uses ODBC to connect to an access database. It also uses header() to force the user to authenticate. Here is the script: <?php require_once('auth.inc'); ?> <html> <head> <title>Enter a new listing</title> </head> <body onLoad="document.all.year.focus();"> <?php if (@$do_save) { ?> Cannot yet save listings. <?php } ?> <script language="JScript"> <?php $allmodels = $dbh->getAll("select make, model, model_description from models"); echo "var allmodels = new Array(new Array(0,0,0)"; foreach ($allmodels as $row) { echo ",\n new Array(", $row[0], ",", $row[1], ", '", $row[2], "'"; echo ")"; } echo ");\n"; ?> function makechanged() { var value = document.all.make.value; var modelopts = document.all.model.options; while (modelopts.length > 0) modelopts.remove(0); if (value == -1) { var popup = open("newmake.php", null, "height=100,width=300,status=yes,toolbar=no,menubar=no,location=no"); } else if (value != 0) { var obj = document.createElement("OPTION"); var i; modelopts.add(obj); obj.value=null; obj.innerText=""; for(i=0;i<allmodels.length;i++) { if (value != allmodels[i][0]) continue; obj = document.createElement("OPTION"); modelopts.add(obj); obj.value=allmodels[i][1]; obj.innerText=allmodels[i][2]; } obj = document.createElement("OPTION"); modelopts.add(obj); obj.value=-1; obj.innerText="Other..."; } } function addnewmake(ident, desc) { var sel = document.all.make; var opts = sel.options; var i; var didit=0; for(i=0;i<opts.length;i++) { if (ident == opts[i].value) { opts[i].innerText=desc; opts[i].selected=true; didit=1; break; } } if (!didit) { var obj = document.createElement("OPTION"); opts.add(obj); obj.value=ident; obj.innerText=desc; obj.selected=true; } makechanged(); } function modelchanged() { var makevalue = document.all.make.value; var makedesc = document.all.make.options[document.all.make.selectedIndex].innerText; var value = document.all.model.value; if (value == -1) { var popup = open("newmodel.php?make_id=" + makevalue + "&make_desc=" + makedesc , null, "height=100,width=300,status=yes,toolbar=no,menubar=no,location=no"); } } function addnewmodel(make, ident, desc) { var i; var foundit = 0; alert("3"); alert("addnewmodel " + make + " " + ident + " " + desc); for(i=0;i<allmodels.length;i++) { if (make == allmodels[i][0] && ident == allmodels[i][1]) { foundit = 1; allmodels[i][2] = desc; break; } } alert("4"); if (!foundit) { i = allmodels.length; allmodels[i] = new Array(); allmodels[i][0] = make; allmodels[i][1] = ident; allmodels[i][2] = desc; } alert("5"); makechanged(); alert("6"); var sel = document.all.model; var opts = sel.options; for(i=0;i<opts.length;i++) { if (ident == opts[i].value) { opts[i].selected=true; break; } } alert("7"); } </script> <h1>New Listing</h1> <form action="listing.php" method=post> <hidden name=do_save value=1> <table border=0> <tr> <th>Year</th> <td><input type=text name=year size=4 id=year></td> </tr> <th>Make</th> <td><?php $allmakes = $dbh->getAssoc("select make, make_desc from makes"); echo "<select name=make id=make onchange=\"makechanged();\">\n"; echo "<option selected></option>\n"; foreach ($allmakes as $makeid => $makedesc) { echo "<option value=$makeid>$makedesc</option>\n"; } echo "<option value=-1>Other...</option>\n"; echo "</select>\n"; ?> </td></tr> <th>Model</th> <td><select name=model onChange="modelchanged();"> </select> </td></tr> </table> </form> </body> </html> auth.inc --------- <?php //************************************** // for :HTTP authentication with PHP on IIS //************************************** // Source: http://brecht.sanders.org/ //************************************** // Name: HTTP authentication with PHP on IIS // Description:A simple way to provide Basic Authentication using PHP on Internet Information Server 4 or 5.
