  • 'Auto' option missing for TreeView subclass

    - by Jared
    I've created a custom control that subclasses TreeView. Right now it's completely empty, doesn't override anything. However when I place an instance in the designer the 'Auto' value for the Width and Height fields is no longer available as it is with the default TreeView. What am I missing?

  • How to get width of button in DateTimePicker-Control/Controls in general?

    - by Inno
    Hello everybody, I implemented a custom DateTimePicker. On the DateTimePicker there is a button. In the examples I've found it's width is set to 16. This is working but I would like to have a dynamic approach. So, is there a way to get the size of this button or is there a general way to get information about .Net-Control sub elements like size etc.? Trying DateTimePicker.Controls didn't help me (it's empty).

  • Uses for the capacity value of a string

    - by dreamlax
    In the C++ Standard Library, std::string has a public member function capacity() which returns the size of the internal allocated storage, a value greater than or equal to the number of characters in the string (according to here). What can this value be used for? Does it have something to do with custom allocators?

  • Animate and form rows, arrays, AS3

    - by VideoDnd
    Question How can I animate and form rows together? Explanation One 'for loop' is for animation, the other 'for loop' is for making rows.

  • How to get the form active control?

    - by PabloG
    Is there a way to get the form active control? I was checking in the help for the "Support.GetActiveControl" method but it isn't supported :) for the Compact Framework. I suppose that I can track the focus by adding a custom GotFocus event handler to all the form controls, but I'm looking for a more generic way that can be implemented for any form.

    autoexp.dat does not seem to take affect in Visual Studio C++ 2005 debugger. I am not trying to add any custom rules. Just want commonly used stuff like stl::string, to display in a friendlier manner. Does anyone know. how I can accomplish this? Is this just question of specifying a path to the autoexp.dat file somewhere. The file is available under the Visual Studio installation directory.

  • IE ignores added onclick attribute

    - by user357034
    The Jquery code below works ok with firefox, Safari, Opera but not with IE. I kinda know why this isn't working in IE after reading a lot about it but I do not know how to fix it. My understanding (I think) is that this method will assign a attribute of "onclick" in IE rather than an event method. Therefore it will not fire in IE and the href fires instead which in this case is "#" which is exactly what is happening. What is the correct way of adding the onclick event. <a id="product_photo_zoom_url" href="/PhotoGallery.asp?ProductCode=9857%2D116%2D003" title="9857-116-003 Ignition box"><img id="product_photo" src="/v/vspfiles/photos/9857-116-003-2T.jpg" border="0" alt="9857-116-003 Ignition box" /></a> <br /><a id="product_photo_zoom_url2" href="/PhotoGallery.asp?ProductCode=9857%2D116%2D003" title="9857-116-003 Ignition box"> <img src="/v/vspfiles/templates/100/images/buttons/btn_largerphoto.gif" border="0"></a> var global_URL_Encode_Current_ProductCode; var global_Config_ProductPhotosFolder; var global_Current_ProductCode; var titleattr = $("a#product_photo_zoom_url").attr("title"); var picurl='tb_show(titleattr, \'/PhotoDetails.asp?ShowDESC=N&ProductCode=\' + global_URL_Encode_Current_ProductCode + \'&TB_iframe=true&height=600&width=520\');return false;' $("a#product_photo_zoom_url").attr('onclick', picurl); $("a#product_photo_zoom_url").attr('href', '#'); $("a#product_photo_zoom_url2").attr('onclick', picurl); $("a#product_photo_zoom_url2").attr('href', '#');

Also I want to order on it Ascending. Should I use a custom MySQL-query?

  • How to show own view in Spinner Widget instead of Text View?

    - by Janusz
    I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item. It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row. I simply want to show an individual icon left from the spinner text for each item in the list.

    I have a picture in Powerpoint 2003, how do I change the picture without having to delete it and re-add it? I need to save all the animations and it's going to take about 5 hours to re add them, but only like 20 mins if I change the pictures. Or if there is anyway to copy a custom animation set to another picture that would also be ace

  • What Getters and Setters should and shouldn't do.

    - by cyclotis04
    I've run into a lot of differing opinions on Getters and Setters lately, so I figured I should make it into it's own question. A previous question of mine received an immediate comment (later deleted) that stated setters shouldn't have any side effects, and a SetProperty method would be a better choice. Indeed, this seems to be Microsoft's opinion as well. However, their properties often raise events, such as Resized when a form's Width or Height property is set. OwenP also states "you shouldn't let a property throw exceptions, properties shouldn't have side effects, order shouldn't matter, and properties should return relatively quickly." Yet Michael Stum states that exceptions should be thrown while validating data within a setter. If your setter doesn't throw an exception, how could you effectively validate data, as so many of the answers to this question suggest? What about when you need to raise an event, like nearly all of Microsoft's Control's do? Aren't you then at the mercy of whomever subscribed to your event? If their handler performs a massive amount of information, or throws an error itself, what happens to your setter? Finally, what about lazy loading within the getter? This too could violate the previous guidelines. What is acceptable to place in a getter or setter, and what should be kept in only accessor methods?

  • Hover-to-click on jQuery UI datePicker 'next month' and 'prev month' not working

    - by user316727
    Hi there, I have a calendar which is meant to look much like the calendar in Outlook. There is a big field representing the hours in a day, and there is a date navigator. The navigator is the jQuery UI Datepicker. I want users to be able to navigate to a new day by clicking on a date in the datepicker, but also to be able to drag appointments over the datepicker and drop them on a specific date. I have that working now. I also want users, while they are dragging an appointment, to be able to move to next or previous month simply by hovering over the datepicker. So I've added a mouseenter and mouseleave event: one runs a setInterval function which sends a click every 1,5 seconds; the other cancels the interval function. This is where all sorts of things go wrong. As soon as one click has been triggered, the mouseleave function no longer works: in other words, the datepicker keeps flipping over to another month every 1,5 seconds. It seems that the datePicker interferes, or that the click event causes other things to go wrong. What can I do?

  • Flex/actionscript 3 equivalents for __FILE__ and __LINE__

    - by Douwe
    Hi all, I'm quite new to flex/actionscript and I was wondering if there is an equivalent for php's (and other languages) FILE and LINE identifiers? Basicly I want to do some custom error logging and would like to something like: var mymessage:String = 'Oops, a hiccup occured at ' + __FILE__ + ', line: ' + __LINE__; Where file and line would ofcourse be substituted for their values at compile time. Is this possible?

  • How can I get the text color of a button using the Substance LaF?

    - by DR
    In my Java application I have to custom-paint a control and for that I need to use the same font colors as JButton. (Enabled an disabled) I don't want to to hard-code them, because the user can change the Substance skin at runtime. I'm aware of the ColorSchemes but I'm not sure how to proceed once I have the color scheme of the current skin. Also the Substance documentation says something about creating your own color scheme, but I just can't figure out the way to retrieve a certain color.

  • Recommendations for a programmable drivers license scanner?

    - by Slapout
    Our motor pool wants to scan drivers’ licenses and have the data imported into our custom system. We're looking for something that will allow us to programmatically get the data from the scanner (including the picture) and let us insert it into our application. I was wondering if anyone has had experience with this type of system and could recommend one or tell us which ones to avoid. Our application is written in PowerBuilder and uses a DB2 database.

  • stop android emulator call

    - by Shahzad Younis
    I am working on an Android application, having functionality like voicemail. I am using BroadcastReceiver to get dialing events. I have to get the event "WHEN CALL IS UNANSWERED (not picked after few rings) FROM RECEIVER". I will do some actions on caller end against this event. I am using AVD emulator, and I do call from one instance to another instance and it calls perfectly, but the problem is: It continuously calls until I reject or accept the call. This way I cannot detect that "CALL IS UNANSWERED AFTER A NUMBER OF RINGS". So I want the Caller emulator to drop the call after a number of rings (if unanswered) like a normal phone. I can do it (drop the call after some time) by writing some code, but I need the natural functionality of phone in the emulator. Can anyone please guide me? Is there any settings in the emulator? Or something else? The code is shown below in case it helps: public class MyPhoneReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle extras = intent.getExtras(); if (extras != null) { String state = "my call state = " + extras.getString(TelephonyManager.EXTRA_STATE); Log.w("DEBUG", state); } }
