asp.net - updating a row gives error Operation must use an updateable query -

-

i'm getting error when i'm trying update record:

error [hy000] [microsoft][odbc microsoft access driver]

operation must use updateable query

however when add new record, add fine.

i did searching , found out problem because asp.net worker process not have permission update database. how being able insert new record (isn't inserting updating database!) not update (set record different value). 

odbcconnection dbconnection = new odbcconnection("dsn=inv"); dbconnection.open();  try {     string newpassword = password1.text;     odbccommand dbcommand = new odbccommand("update users" + " set [password] = '" + newpassword + "'" + " name = '" + session["loginid"] + "'" + ";", dbconnection);     dbcommand.executenonquery();     server.transfer("default.aspx", true); }

you error if don't have primary key declared on table.

your code pretty ugly, @ least should using parameterized query: 

odbccommand dbcommand = new odbccommand("update users set [password] = @password name = @name", dbconnection); var param = dbcommand.parameters.add("@password", odbctype.text); param.value = password; param = dbcommand.parameters.add("@name", odbctype.text); param.value = session["loginid"];

and hope isn't more toy/demo app -- storing passwords in clear bad. storing passwords in access in clear double bad.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
