if check current page success message moodle. file not in destinated container. tried several modifications code , action parameter of form corresponding 'documentation' of filepicker.php no avail. if fill out form in firefox, works fine. if skip setvalue-call, failure message. seems happen.

maybe associated additional hidden fields? appreciated. use javascript , yui-functionality, if feasible solution.

is strange javascript needs disabled able upload file.

anyhow, real chrome:

  1. go http://demo.moodle.net/course/modedit.php?update=1&return=1
  2. click 'add'
  3. 'upload file'
  4. upload actual file
  5. 'the file has been uploaded successfully'
  6. refresh page (http://demo.moodle.net/course/modedit.php?update=1&return=1)
  7. "no files available"

so, how 1 can check if file correctly uploaded? , there way upload file javascript enabled.

as side note, better click() hyperlink, so:

currentpage = anchors.get(0).click();

instead of 

currentpage = (htmlpage) browser.getpage(anchors.get(0).gethrefattribute());

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.
