vb.net - vb net load multiple datagrid at n one form and automatic progress bar -


i have 2 datagrid , 2 button in 1 form..

if click go!, left datagrid filled data..

and if click mining!, surely right datagrid filled..

but problem when click mining button, right datagrid filled, but left datagrid's data automatically unloaded, resulting right datagrid loaded data..

here's screenshot

enter image description here

so need 2 datagrid display data @ same time..

is possible that?

and 1 more question there simple way automatically display progress bar when click mining button, because when clicked it, run executequery took long time completed, it's 10 60 seconds..

so show program not hang, it's still working on progress completed..

only simple circle progress bar do, mean there's no need display estimated time complete.. said before, it's show program working on progress not hang

and way i'm using vb.net , mysql.. before

updated code

if .....  getcmd= "insert node(...) select ..." cmd = new mysqlcommand(getcmd, conn.connect) cmd.executenonquery() cmd.connection.close()  elseif ...     getcmd= "insert node(...) select ..."     cmd = new mysqlcommand(getcmd, conn.connect)     cmd.executenonquery()     cmd.connection.close()  else     getcmd= "insert node(...) select ..."     cmd = new mysqlcommand(getcmd, conn.connect)     cmd.executenonquery()     cmd.connection.close()  end if

if left grid getting cleared, check code, or post here because not normal, must clearing grid @ somepoint. search code [gridname].datasource = nothing or if using bindingsource, [bindingsourcecontrolname].clear. without more information on how fill grid, cannot give better answer.

as progress bar, need asyncronous call or multi-threading able show progress while making single call executequery. way can still run code while call running. there third-party grids have option built in not standard ms grids.

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 .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
