vb.net - InvalidArgument=Value of '0' is not valid for 'SelectedIndex'. Parameter name: SelectedIndex using ShowDialog -


i have vb6 project have converted on .net using visual studio 2008. have code uses showdialog. code worked fine in vb6. in vs 2008 code doesn't throw error during build or compile. error @ run time, error:

an error occurred creating form. see exception.innerexception details. error is: invalidargument=value of '0' not valid 'selectedindex'. parameter name: selectedindex

this code error thrown on:

frmaddmethod.showdialog()

the call stack:

prjdrawsafe.exe!prjdrawsafe.frmmain.cmdadddrawing_click(object eventsender = {text = "add drawing"}, system.eventargs eventargs = {x = 59 y = 8 button = system.windows.forms.mousebuttons.left}) line 60 basic

can please tell me how fix error code work in .net/?

one of controls on converted form has selectedindex property set 0 not supported in .net. there couple of ways sort out:

search 'generated form designer code' (or whatever name is) region selectedindex property of control , fix one(s) zero.

manually select each control in form designer , check selectedindex property, change zero.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
