c# - Connect to a database not created yet? -


how create sql compact edition database? have tried figure out, searched internet , cant find (but again, how search this?!). here code far:

checkpasswordsmatch(); sqlceconnection myconn = new sqlceconnection(); sqlcecommand mycommand = new sqlcecommand(     @"create database ""pwdb.sdf"" databasepassword '" + textbox1.text + "'"); mycommand.executenonquery();

what put on connection part? dont understand.

update: decided create database incorporate application, , check if there value (admin password) dedicated record master.

here new code:

application.enablevisualstyles();         application.setcompatibletextrenderingdefault(false);         sqlceconnection myconn = new sqlceconnection("data source = pwdb.sdf;");         sqlcecommand checkpass = new sqlcecommand("select * pw name = master;",myconn);         try         {             myconn.open();         }         catch (exception ex)         {             messagebox.show(ex.tostring());         }         if (checkpass.executenonquery() != null)         {             application.run(new entermasterpassword());         }         else             application.run(new mainpassset());

the problem is, when execute now, get:

an unhandled exception of type 'system.data.sqlserverce.sqlceexception' occurred in system.data.sqlserverce.dll

any ideas anyone??

try using sqlceengine class. class can create new database:

using (sqlceengine engine = new sqlceengine()) {     engine.localconnectionstring = yourconnectionstring;     engine.createdatabase(); }

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
