c# - Does Microsoft ReportViewer require special handling to Dispose correctly? -


i've spent last day tracking down seems memory leak issue in code, , believe have pinned down culprit - report generation. in order see problem lies created empty solution, button on blank form, linked event:

    private void button1_click(object sender, eventargs e)     {          (int = 0; < 10000; i++)         {             microsoft.reporting.winforms.reportviewer temp = new microsoft.reporting.winforms.reportviewer();             temp.dispose();         }     }

opening form , clicking button, watch windows task manager , can see memory begin climbing, along user objects, in matter of minutes hits cap of 10,000 , causes win32exception: unable create handle.

debugging line line, can see on creation user objects goes 7, , on dispose goes down 5.

i have tried temp.localreport.releasesandboxappdomain() based on other issues people having, i've tried same loop using around report viewer, see if behaved differently - didn't.

my question is, there special handling around reportviewer missing?

(fyi, i'm working on .net framework 4 microsoft.reportviewer.winforms version 10)

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.
