vb.net - Method/Property Error on New SQL Server Connection -


i'm running vb .net in vs2013, on windows 8 on sql server 2008 r2, , creation of sql connection failing error:

property access must assign property or use value.

here's code:

dim ocnn sqlconnection dim scnn string dim bsuncnnok boolean

try     if vssunserver <> ""         scnn = "provider=sqloledb.1;" & _                "integrated security=sspi;" & _                "persist security info=false;" & _                "initial catalog=sunsystemsdata;" & _                "data source=" & vssunserver         ocnn = new sqlconnection(scnn)         ocnn.open()         bsuncnnok = true     end if catch ex exception     bsuncnnok = false end try

_vssunserver_ string being passed in sub, , has run-time value of "svrsun07".

the error being raised on line:

ocnn = new sqlconnection(scnn)

so @ run-time, scnn holds:

"provider=sqloledb.1;integrated security=sspi;persist security info=false;initial catalog=sunsystemsdata;data source=svrsun07"

i've lifted connection string .udl file, returns successful when test connection.

i can run sqlsms on database ok.

below ascii art diagram shows how components related each other. trying use sql oledb connection string sqlconnection. these things don't go together. 

c#/vb.net code -┬------------> sqlconnection -----------------┬-> sql server                 |                                             |                 ├--> oledbconnection -┬-> sql oledb provider -┤                 |                     |                       |                 |       native code --┤                       |                 |                     |                       |                 └-> odbcconnection ---┴-> sql odbc driver ----┘

if want use sql oledb native provider can use oledbconnection. might useful if want vb.net code flexible , possible connect other oledb providers such access, postgres, mysql, etc.

however if know sure connecting sql server easier use sqlconnection instead connection string "integrated security=sspi;persist security info=false;initial catalog=sunsystemsdata;data source=svrsun07".

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
