• How to intercept capture TAB key in WinForms application?

  - by Axarydax

  Hi, could you please help me with this one? I'm trying to capture Tab key in Windows Forms application and do a custom action on it. I have a Form with several listViews and buttons, I've set Form's KeyPreview property to true and when I press any other key than tab, my KeyDown event handler does get called. But that's not true with the Tab key - I don't receive WM_KEYDOWN message even in WndProc. Do I need to set each control inside my form - its TabStop property - to false? There must be a more ellegant way that that. Thanks.

  - by tommy-susanto

  I need to quit firefox and restart it in order for the applet to be refreshed... its anoying since i'm still programming it an the class files changes... am i missing some codes which makes it unable to refresh the applet and still take the one from the cache??? So I have a .jar applet in my website, a simulation game that spawns army whenever user clicks on the screen... however whenever I refresh the page, the previous army are still there on the screen.. I want it to be refreshed (as if we're just starting to run the application the first time). I already tried pressing CTRL+f5 but the trick doesn't seem to work I'd basically like to do it automatically using scripts or something, so that it won't require user to manually press some button on the keyboard Any Suggestions? I'd really appreciate it Thank you....

• UISearchBar animation hidding button

  - by David Carvalho

  Hello I currently have a UISearchBar (attached to a UISearchDisplayController), but I reduced the width of the search bar so I could display a custom button to its right when the search bar is not selected. The button is used to access other views. However, when I select the search bar and then press cancel (or even perform a search) and return to the normal view, where the search bar should be displayed with my custom button, the search bar animates and takes up all the room for the button and the is not displayed. Essentially, the search bar takes up all the width of the screen when I only want it to take up a part of it. Is there any way to prevent the search bar from animating to the whole width of the screen? This is how I defined the CGRect of the search bar: self = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 250.0f, 45.0f)] Any help would be great. Regards

• accepts_nested_attributes_for ignore blank values

  - by Mike

  i have class Profile has_many :favorite_books, :dependent => :destroy has_many :favorite_quotes, :dependent => :destroy accepts_nested_attributes_for :favorite_books, :allow_destroy => true accepts_nested_attributes_for :favorite_quotes, :allow_destroy => true end I have a dynamic form where you press '+' to add new textareas for creating new favorites. What i want to do is ignore the blank ones, I find this harder to sort through in the update controller than a non nested attribute. What i have temporarily is a hack in the after_save callback deleting the empty records. Whats the most rails way to ignore these blank objects? I dont want validation and errors, just a silent deletion/ignore.

• Javascript won't overwrite CSS display property.

  - by Sorin Buturugeanu

  I have a DIV that is set do display:none from CSS and it's supposed to be made visible (style.display = '';) at some point by javascript. The problem is that if I put the display:none in the CSS file the javascript does not seem to have any effect. I have also tried changing the background color instead of the display property, and that works. I have the code running here (just press the edit link). I really thank you for taking the time to look into this.

• Groovy: How to access objects with Id tag?

  - by skifan0

  Hello, I have the following Groovy+SwingBuilder code. In one panel I generate checkboxes and in another panel I want to access the values of the checkboxes. The code looks basically likes this: def optionsmap = [ foo : "value_foo", bar : "value_bar"] SwingBuilder.build() { frame(title:'demo1', size:[400,700], visible:true, defaultCloseOperation:WC.EXIT_ON_CLOSE) { gridLayout(rows: 1, cols: 2) panel(id:'optionPanel', constraints:java.awt.BorderLayout.CENTER) { gridLayout(rows: 5, cols: 1) myGroup = buttonGroup(); for (entry in optionsmap) { checkBox(id: entry.key, text: entry.value ) } } panel(constraints:java.awt.BorderLayout.WEST) { button ('Show values', actionPerformed: { for (entry in optionsmap) { println (entry.key as Class).text } }) } } } optionsmap is a map with (id, text) pairs that can be extended. When I press "show values" I get an error message: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'foo' with class 'java.lang.String' to class 'java.lang.Class' How could I access the checkboxes for my action in the second panel by using the checkbox ids from optionsmap? Thank you if you can help

• Robustly killing Windows programs stuck reporting 'problems'

  - by grrussel

  I am looking for a means to kill a Windows exe program that, when being tested from a python script, crashes and presents a dialog to the user; as this program is invoked many times, and may crash repeatedly, this is not suitable. The problem dialog is the standard reporting of a Windows error: "Foo.exe has encountered a problem and needs to close. We are sorry for the inconvenience" and offers a Debug, Send Error Report, and Don't Send buttons. I am able to kill other forms of dialog resulting from crashes (e.g. a Debug build's assert failure dialog is OK.) I have tried taskkill.exe, pskill, and the terminate() function on the Popen object from the subprocess module that was used to invoke the .exe Has anyone encountered this specific issue, and found a resolution? I expect automating user input to select the window, and press the "Don't Send" button is one possible solution, but I would like something far simpler if possible

• How to stop the Bottle webserver when started from subprocess

  - by luc

  Hello all, I would like to embed the great Bottle web framework into a small application (1st target is Windows OS). This app starts the bottle webserver thanks to the subprocess module. import subprocess p = subprocess.Popen('python websrv.py') The bottle app is quite simple @route("/") def index(): return template('index') run(reloader=True) It starts the default webserver into a Windows console. All seems Ok except the fact that I must press Ctrl-C to close the bottle webserver. I would like that the master app terminates the webserver when it shutdowns. I can't find a way to do that (p.terminate() doesn't work in this case unfortunately) Any idea? Thanks in advance

• ASP.NET variable scope

  - by c11ada

  hey all, im really new to ASP.Net and still havnt got my head round most of the concepts, im really having problems with variable, when creating a desktop application, any variable created in code for example int n = 10; this variable will be there until the program is running right. but in asp iv created variables which are supposed to last until the user gets of that page, so for example say i have a page which takes the users value ( call this variable n say the user type in 10) and every time the user presses the next button the code add 10 to this value. so the first time the user presses the next button n= n + 10; what i have found is no matter how many times i press the next button n will always equal 20, because the previous value is not saved !! these values are populated the first time the user enters that page, once the user clicks the next button the content of these values disappear! how can stop this from happening ?? hope this makes sense !! thanks

• Changing drag cursor in VirtualTreeView

  - by Coder12345

  When using VirtualTreeView drag operation by default is [doCopy,doMove]. Move operation is indicated by arrow pointer with small box and Copy operation is indicated by same pointer icon but with added [+] next to it. By default VT uses copy operation and if you press modifier key (SHIFT key) it modifies operation to move therefore removing the [+] from pointer. Here is what I need: reverse the operations (default would be move, with modifier key pressed - copy) and thus reverse pointer arrow too replace modifier key - CTRL instead of SHIFT read in an event which of the two operations occurred and start copy or move operation Any pointers into right direction(s) appreciated.

• Help needed in Javascript + Image + HREF

  - by Bragaadeesh

  Hi, <a href="#"><img src="http://www.google.com/intl/en_ALL/images/logo.gif" onClick="alert('hi')"/></a> In the above code, i am appending a javascript onclick method to the image tag. When I click the image once and I press back, it should go back to the page it came from. Instead its staying on the same page. Is there any way I can avoid that? (probably set something else instead of href="#"). The reason I set href="#" is to make my cursor turn into hand, other than that it has no use. This is occuring in FIREFOX, IE it works fine Please help. Thanks.

• Does anyone know how to create a message bubble with 2 buttons appears on top of an overlayitem for

  - by Zap

  I currently have implemented an overlayitem that shows an icon for geopoint on a map application in Android. When the icon is clicked, it brings up an AlertDialog from the onTap method below. I have the following questions: Does anyone know how to display a map message bubble directly above the icon overlayitem with 2 callout buttons one to the left of the title and one to the right of the bubble? Does anyone know how to make the overlayitem draggable so I can press and hold it and drag it across the map. I am trying to duplicate the draggable icon behavior that's available on the iPhone. If so, please share some sample code. Thanks protected boolean onTap(int index) { OverlayItem item = mOverlays.get(index); AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); dialog.setTitle(item.getTitle()); dialog.setMessage(item.getSnippet()); dialog.show(); return true; }

• asp.net - csharp - jquery - looking for a better and usage solution

  - by LostLord

  hi my dear friends i have a little problem about using jquery...(i reeally do not know jquery but i forced to use it) i am using vs 2008 - asp.net web app with c# also i am using telerik controls in my pages also i am using sqldatasources (Connecting to storedprocedures) in my pages my pages base on master and content pages and in content pages i have mutiviews ================================================================================= in one of the views(inside one of those multiviews)i had made two radcombo boxes for country and city requirement like cascading dropdowns as parent and child combo boxes. i used old way for doing that , i mean i used update panel and in the SelectedIndexChange Event of Parent RadComboBox(Country) i Wrote this code : protected void RadcomboboxCountry_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e) { hfSelectedCo_ID.Value = RadcomboboxCountry.SelectedValue; RadcomboboxCity.Items.Clear(); RadcomboboxCity.Items.Add(new RadComboBoxItem(" ...", "5")); RadcomboboxCity.DataBind(); RadcomboboxCity.SelectedIndex = 0; } my child radcombo box can fill by upper code , let me tell you how : the child sqldatasource have a sp that has a parameter and i fill that parameter by this line - hfSelectedCo_ID.Value = RadcbCoNameInInsert.SelectedValue; RadcbCoNameInInsert.SelectedValue means country ID. after doing that SelectedIndexChange Event of Parent RadComboBox(Country) could not be fire therefore i forced to set the autopostback property to true. afetr doing that every thing was ok until some one told me can u control focus and keydown of your radcombo boxes (when u press enter key on the parent combobox[country] , so child combobox gets focus -- and when u press upperkey on child radcombobox [city], so parent combobox[country] gets focus) (For Users That Do Not Want To Use Mouse for Input Info And Choose items) i told him this is web app , not win form and we can not do that. i googled it and i found jquery the only way for doing that ... so i started using jquery . i wrote this code with jquery for both of them : <script src="../JQuery/jquery-1.4.1.js" language="javascript" type="text/javascript"></script> <script type="text/javascript"> $(function() { $('input[id$=RadcomboboxCountry_Input]').focus(); $('input[id$=RadcomboboxCountry_Input]').select(); $('input[id$=RadcomboboxCountry_Input]').bind('keyup', function(e) { var code = (e.keyCode ? e.keyCode : e.which); if (code == 13) { -----------> Enter Key $('input[id$=RadcomboboxCity_Input]').focus(); $('input[id$=RadcomboboxCity_Input]').select(); } }); $('input[id$=RadcomboboxCity_Input]').bind('keyup', function(e) { var code = (e.keyCode ? e.keyCode : e.which); if (code == 38) { -----------> Upper Key $('input[id$=RadcomboboxCountry_Input]').focus(); $('input[id$=RadcomboboxCountry_Input]').select(); } }); }); </script> this jquery code worked BBBBBBUUUUUUUTTTTTT autopostback=true of the Parent RadComboBox Became A Problem , Because when SelectedIndex Change Of ParentRadComboBox is fired after that Telerik Skins runs and after that i lost parent ComboBox Focus and we should use mouse but we don't want it.... for fix this problem i decided to set autopostback of perentCB to false and convert protected void RadcomboboxCountry_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e) { hfSelectedCo_ID.Value = RadcomboboxCountry.SelectedValue; RadcomboboxCity.Items.Clear(); RadcomboboxCity.Items.Add(new RadComboBoxItem(" ...", "5")); RadcomboboxCity.DataBind(); RadcomboboxCity.SelectedIndex = 0; } to a public non static method without parameters and call it with jquey like this : (i used onclientchanged property of parentcombo box like onclientchanged = "MyMethodForParentCB_InJquery();" insread of selectedindexchange event) public void MyMethodForParentCB_InCodeBehind() { hfSelectedCo_ID.Value = RadcomboboxCountry.SelectedValue; RadcomboboxCity.Items.Clear(); RadcomboboxCity.Items.Add(new RadComboBoxItem(" ...", "5")); RadcomboboxCity.DataBind(); RadcomboboxCity.SelectedIndex = 0; } for doing that i read the blow manual and do that step by step : ======================================================================= http://www.ajaxprojects.com/ajax/tutorialdetails.php?itemid=732 ======================================================================= but this manual is about static methods and this is my new problem ... when i am using static method like : public static void MyMethodForParentCB_InCodeBehind() { hfSelectedCo_ID.Value = RadcomboboxCountry.SelectedValue; RadcomboboxCity.Items.Clear(); RadcomboboxCity.Items.Add(new RadComboBoxItem(" ...", "5")); RadcomboboxCity.DataBind(); RadcomboboxCity.SelectedIndex = 0; } so i recieved some errors and this method could not recognize my controls and hidden field... one of those errors like this : Error 2 An object reference is required for the non-static field, method, or property 'Darman.SuperAdmin.Users.hfSelectedCo_ID' C:\Javad\Copy of Darman 6\Darman\SuperAdmin\Users.aspx.cs 231 13 Darman any idea or is there any way to call non static methods with jquery (i know we can not do that but is there another way to solve my problem)???????????????

• Jquery Live Validation

  - by sico87

  Hello Everyone, After having a search around I could not find exactly what I want, I am looking to validate a form client side using the Jquery library and some form of validation plugin. I was hoping that some one could advise me on whether there are any validation plugins out there that do not use generic error messages, as my form is laid out with no room for these errors, and I also I want the validator to to for correct content as well. Basically I want to be able to check the field on each key press and blur and if the fields validates for it to gain a green border, and if it does not validate for it to gain a red border, any one know of a plugin that can do this? Thanks sico87

• Experience with laptop Keyboards?

  - by Omar Kooheji

  I'm thinking of retiring my 3 year old HP laptop I want to know which manufacturor makes laptops with the best Keyboards? I loved my Full width keyboard, with numberic pad on my HP, I've tried a a few laptop keyboards in shops and have found none of them satisfying to type with. What I want is something that will maximise my typing comfort. All the ones I see in shops seem to be designed to look good but feel horible. The keys are either too shiny, too small, or don't press down enough. All I want it a keyboard thats comfortable, I've been given a Lenovo laptop by my work and I've had to resort to pluging in a USB keyboard while I work, which is less than ideal.

• Cocoa-Binding : Submit changes manually?

  Hello in my application I have a NSTableView bound to an ArrayController (arrangedObjects). I also have a Details-View (just some textfields) bound to the same Controller (selection). Now every time I edit a textfield the changes are automatically send to the ArrayController and the Table changes as well. How can I avoid this? What I want is a "Submit-Button". Changes on the data should only be send to the controller when I press the button and not automatically every time I do an edit.

• How do I keep existing values from shifting to the right when entering keypresses into a jQuery Mask

  - by Andrew

  I have a text box I'm using as a timer display "hh:mm:ss" When I select the box and press a number, it inserts the number at the cursor location, but instead of replacing the value at that position, it shifts all existing values over. For example, the timer text box reads "01:00:35" and I replace the first minute position with 1, the timer text box will then read "01:10:03." Anybody know how to force the text box to replace, instead of insert, at the cursor position? I've tried intercepting onKeyPress, doing the replace manually, rewriting the entire timer text, and then returning false. But, that doesn't worked with a jQuery masked input, because my function runs first.

• Preferred way of using UiBinder with multiple screens

  - by arinte

  We have a GWT app that has multiple screens, based off of a menu. So App loads user sees Do This Do That Each menu item loads a different screen. What is the best way to switch the screens. Right now what I do roughly is RootPanel.get(CONTENT).remove(menu); RootPanel.get(CONTENT).add(new DoThisScreen()); I ask this because it seems on IE 8 (and I am sure 7,6) that the DoThisScreen is basically not recognize by IE's Developer Tool (wannabe firebug tool, when you press F12). Using IE's dev tool I tell it to highlight a textbox in the DoThisScreen, for some reason it won't highlight it or list it in the html.

• Does Eclipse has a plugin for code clips like in Coda?

  - by Sinan Y.

  There is a very useful "Clips" feature in Coda, do we have such thing in Eclipse? What it does is pretty simple, you save once a code clip which you use very often and assign it a shortcut and when you want to re-use it on editor you type the shortcut you assigned and it automatically pastes that code clip and sets caret position to the defined position. On the example here (second image) when i write 4dom and press TAB afterwards it types me this... jQuery(function($){ //puts cursor here }); Since it is a very useful feature i miss that one on Eclipse, is there a plugin for this? Thanks, Sinan.

• How to re-focus to a text field when focus is lost on a HTML form?

  - by Horace Ho

  There is only one text field on a HTML form. Users input some text, press Enter, submit the form, and the form is reloaded. The main use is barcode reading. I use the following code to set the focus to the text field: <script language="javascript"> <!-- document.getElementById("#{id}").focus() //--> </script> It works most of the time (if nobody touches the screen/mouse/keyboard). However, when the user click somewhere outside the field within the browser window (the white empty space), the cursor is gone. One a single field HTML form, how can I prevent the cursor from getting lost? Or, how to re-focus the cursor inside the field after the cursor is lost? thx!
