c# - Sending command to showDialogue Form from inactive form -

-

i want send keys show dialogue form inactive form.see picture

enter image description here

form showing dialogue.behind form has customized keyboard , numpad. send keys against these button clicks. how possible can send keys keyboard show dialogue form.

what you're asking impossible. once understand how modal dialogs work (forms shown using showdialog method modal), understand why. modal dialog used when want force user interact only dialog. prevents them interacting other windows in application disabling windows. become impervious mouse clicks, don't receive keyboard input, , can't receive focus. windows beeps @ , flashes title bar of modal dialog when try, it's non-subtle way of shaking head , saying "no, no, no".

so what's going on here when show "deposits" form modal dialog using showdialog method, of other windows in application disabled. in particular case, means window contains on-screen keyboard disabled, too, , can't receive mouse click events. that's why nothing happening when try click on "keys" (buttons).

the easiest workaround (as suggested in comment) show "deposits" form non-modal dialog using show method instead. unlike modal dialog, not disable other windows in application, allowing user interact of them @ once. clicking on window set focus window , allow process input events. isn't workable you, because want "deposits" form disable every control on main window, not on-screen keyboard.

of course, lied @ beginning when said "impossible". meant is it's tricky, , require work around standard windows interactivity model. couple of ideas
on how might go doing spring mind:

  1. you use on-screen keyboard utility included recent versions of windows. microsoft provides program purpose. don't have build , maintain own, includes necessary logic prevent stealing focus when user clicks on 1 of "keys", , since isn't part of program, won't disabled when show forms modal using showdialog method. check out, go start -> run , type osk.

    for example, in windows 7 looks this:

    on-screen keyboard in windows 7

  2. if insist on using own, custom-designed on-screen keyboard, have show child window of modal dialog. is, application starts main form, per usual. then, when show "deposits" form modal dialog using showdialog method, main form gets disabled. "deposits" form, can show on-screen keyboard form using non-modal show method. main form still disabled, because it's showing modal dialog (the "deposits" form). "deposits" form not disabled, because it's showing non-modal dialog (your on-screen keyboard).

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
