  • How to close a form in UserControl

    - by FJPoort
    I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that. Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code: private void btnCancel_Click(object sender, EventArgs e) { ProjectInfo infoScreen = (ProjectInfo)this.Parent; infoScreen.Close(); } This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?

  • Java long task - Did it stop writing to file?

    - by rockit
    I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

  • 2 Google Tag Manager containers = double triggers?

    - by fred
    I have a Joomla website with existing analytics done by a GTM tag and I need to add another image tag (1x1 pixel) from a separate GTM container. I set the event name for the additional GTM container to a different name from from the existing GTM container (default 'gtm.js') so that the new tag only fires under the specified event. The new container tested out fine in a blank HTML page, but when it is put in the website, it ends up firing twice. I know that because Firebug showed 2 1x1 pixels being loaded and I mark each request with a randomly-generated UID to distinguish them on the server side. I suspect this being caused by having multiple GTM container tags but want to check whether anyone has run into this problem before? As of now, I could not verify nor fix the double counting problem.

  • Need instructions on how to create wpa_supplicant.conf and add fast_reauth=0 to it

    - by nutty about natty
    Like many other natty users on a university/academic network, I'm experiencing annoying frequent disconnects/hangs/delays. See, for instance here. I would like to learn how to add fast_reauth=0 to the wpa_supplicant.conf file. This file, it seems, does not exit by default, and needs to be manually created first: README You will need to make a configuration file, e.g. /etc/wpa_supplicant.conf, with network configuration for the networks you are going to use. Further, I installed wpa_gui which probably needs to be launched with parameters, else it's pretty blank... What I'm hoping for is this: That creating a wpa_supplicant.conf file with fast_reauth=0 in it, saving it to the relevant path, will work and make my uni wireless (more or even completely) stable. I read mixed reviews about wicd (as an alternative to the network manager). Also note that on my basic wlan at home (with bog-standard wpa encryption) the connection is stable. Thanks!

  • Detecting touch area on Android

    - by HappyAppDeveloper
    Is it possible to detect every pixel being touched? More specifically, when the user touches the screen, is it possible to track all the x-y coordinates of the cluster of points touched by the user? How can I tell the difference between when users are drawing with their thumb and when they are drawing with the tip of a finger? I would like to reflect the brush difference depending on how users touch the screen, and would also like to track x-y coordinates of all the pixels being touched over time. Thanks so much in advance for any help.

  • What's the best route to getting started in moble app development?

    - by Rob Z
    As per the question title, I'm interested in starting up a new side project and I'm currently looking at doing a bit of mobile development as said project. I'm actually in a bit of a good position right now as I have a blank slate in front of me (i.e. not locked into a phone already) but on the same token, I also don't want to invest too much money into hardware and the like since this will likely not be a money making venture. As such, which platform provides the best flexibility in terms of experimentation and learning opportunities? Likewise, what are some useful resources to assist in the process?

  • show activity indicator while loading ViewController

    - by Crystal
    I have a ViewController that takes time to load its views. When I run Instruments, I see from the home screen, if I tap on the icon that pushes that view controller onto the stack, it's half laying out the views, and half getting the data for the views. I tried adding an activity indicator to display on the home screen over the button when the button is pressed to push the LongRunningViewController onto the stack. So I basically do this: - (IBAction)puzzleView:(id)sender { dispatch_async(dispatch_get_main_queue(), ^{ [self.activityIndicator startAnimating]; }); PuzzleViewController *detailViewController = [[[PuzzleViewController alloc] init] autorelease]; [self.navigationController pushViewController:detailViewController animated:YES]; [self.activityIndicator stopAnimating]; }

  • [Android] Weird black line on top of list view

    - by CaseyB
    I am creating a layout with a ListView and at the very top of the list there is this weird black line that I can't seem to figure out how to get rid of! It's part of the ListView because it moves up and down as I size the ListView. Has anyone ran into this before? I couldn't get DDMS to take a screen capture for some reason so I took a picture of the screen with my G1, so please forgive the quality! As you can see the line is there at the top of the fade out in the list.

  • Is there a phrase or word to describe an algorithim or program is complete in that given any value for its arguments there is a defined outcome?

    - by Mrk Mnl
    Is there a phrase or word to describe an algorithim or programme is complete in that given any value for its arguments there is a defined outcome? i.e. all the ramifications have been considered whatever the context? A simple example would be the below function: function returns string get_item_type(int type_no) { if(type_no < 10) return "hockey stick" else if (type_no < 20) return "bulldozer" else return "unknown" } (excuse the dismal pseudo code) No matter what number is supplied all possibiblites are catered for. My question is: is there a word to fill the blank here: "get_item_type() is ______ complete" ? (The answer is not Turing Complete - that is something quite different - but I annoyingly always think of something as "Turing Complete" when I am thinking of the above).

  • ncurses - expect: sleep executes at wrong time

    - by rahul
    I have some ncurses apps that I need to automate to test repeatedly. I am placing the "sleep" command between "send" commands. However, what i see is that all the sleep's are executed in the beginning before the screen loads. expect concatenates the sends (I see that at the screen bottom during sleep) then issues them together. I have tried sending all keys with "send -s" or "send -h". That marginally helps. I've replaced "-f" on line 1 with "-b" - again a tiny difference. Why isn't "sleep" pausing at the right time. Incidentally, my programs have a getc() loop, so i can't use "expect" command. I tried that too. #!/usr/bin/expect -f spawn ruby testsplit.rb #expect set send_human {3 3 5 5 7} set send_slow {10 1} exp_send -s -- "--" exec sleep 3 send -s "+" send -s "=" sleep 1 send -h -- "-" send -h -- "-" sleep 1 send -h -- "v" interact

  • LXDE will not suspend when laptop lid is closed, and will die when woken up

    - by user46061
    I am not an experienced Linux user, although I have been using Ubuntu occassionally some time already. ( Since Feisty Fawn probably? ). Now I installed Ubuntu 11.10 and it is nice ( well, after I installed LXDE, Unity sucks and I didn't really like gnome-fallback-session ), but it has one problem: After being suspended, when I wake my computer up, it starts up and in about 5 seconds it dies. Like a normal shutdown. Then, when I start it again, the screen stays blank, so I have to hard-turn it off - only then, when I turn it on, it works. It is an MSI laptop, about 3-4 years old. The second problem is: After installing LXDE, when I close the laptop lid, it does not suspend. I can only suspend using the shutdown menu - and the waking up problem remains. Many thanks for your time and advice guys.

  • WPF Manipulation and Touch events not firing, but mouse events do?

    - by Smetad Anarkist
    I have a Samsung LD220Z multi touch monitor, and when I'm experimenting with some WPF and touch features the touch events arent firing. The mouse down event seems to be firing however. Does this mean that I have to take into account that not all touch screen behave the same, and how do I get the touch inputs on my screen? I've tried the Windows 7 Touch pack that microsoft released. And the multi touch features seems to work there. Any suggestion on how to proceed with this?

  • ActionScript display zero value

    - by bwong
    It seems the number Datatype handles zeros and nulls the same. I need to display a zero value on the screen, but AS displays nothing. When it's saved, the value is saved as a zero, and therefore shows up zero on the screen. Is there a way to display the zero value using a new object? public class myObject{ private var numVar:Number } My AS file: var temp:MyObject temp.numVar = 0; When I debug, temp.numVar contains a value of 0, but does not show anything on the UI. If this object is then saved to the DB, and then displayed to the UI, it shows a 0. My question is - how do I get temp.numVar to display 0 before persistenting it to the DB?

    The Search Contract feature helps improve the accessibility of your application. When a user is trying to search for something through the charms, you see a bunch of apps that get listed below.
