  • SendMessage (F4) fails when sending it to window

    - by Olli
    Working with Visual Studio 6 (VC++ 6.0) I'm using an ActiveX datepicker control which I fail to show expanded by default (3006216). Alternatively I'm trying to send a keyboard message (F4) to my window to open up the control, but nothing happens when I do so... // try 1: use the standard window handle LRESULT result = ::SendMessage(m_hWnd,VK_F4, 0, 0); // try 2: use just use the SendMessage result = SendMessage(VK_F4); result is always 0 - what can I do to test/verify the message sending? Thanks in acvance a lot... Olli

  • Xcode 4 Tips and Tricks for Xcode 3 users

    - by Ben Clayton
    As most of you have probably seen, Xcode 4 has been released officially today. Now I know that plenty of devs out there have been using the preview versions, and it'd be great if people could post any great tips, tricks, or keyboard shortcuts they've learned using those version now they're no longer under NDA. This could be especially useful for those upgrading from Xcode 3 (like me, downloading right now). Note: Apple have released a 'transition guide' that has plenty of stuff in about getting from version 3 to version 4, but I bet there are loads of great tricks people out there have learned that aren't in there.

  • Ignore carriage returns in scanf before data.... to keep layout of console based graphics with conio

    - by volting
    I have the misfortune of having use conio.h in vc++ 6 for a college assignment, My problem is that my graphic setup is in the center of the screen... e.g. gotoxy( getcols()/2, getrows()/2); printf("Enter something"); scanf( "%d", &something ); now if someone accidentally hits enter before they enter the "something", then the cursor gets reset to the left of the screen on the next line. Iv tried flushing the keyboard and bios buffers with fflush(stdin) and getchar(), which like I expected didn't work! Any help/ideas would be appreciated, Thanks, V

  • How to get the last windows active time by windows api

    - by Edwin Tai
    In general, the Screensaver will run when we do nothing for a period of time. Now i wanna know how to get the unactive time. In another word,i want to make a program which would run a function if we do nothing for a period of time. Now i can use mouse or keyboard hook to solve the problem. But you know,it needs administrator permissions. In another word,if in win vista or win 7,it is nauseating because of the UAC. I need an API such to get last windows active time.

  • Can I prevent Flash's Input Events from stacking up when my framerate low?

    - by Matt W
    My Flash game targets 24 fps, but slows to 10 on slower machines. This is fine, except Flash decides to throttle the queue of incoming MouseEvent and KeyboardEvents, and they stack up and the Events fall behind. Way behind. It's so bad that, at 10 fps, if I spam the Mouse and Keyboard for a few seconds not much happens, then, after I stop, the game seems to play itself for the next 5 seconds as the Events trickle in. Spooky, I know. Does anyone know a way around this? I basically need to say to Flash, "I know you think we're falling behind, but throttling the input events won't help. Give them to me as soon as you get them, please."

  • GridView items are displaying the wrong drawables sometimes.

    - by originalbryan
    I've implemented a GridView based on this tutorial. It works great unless open up the search dialog or rotate the screen then scroll around. When the search dialog and virtual keyboard appear, the drawables for each of my grid items shift. I can click on them and they do what I expect, except the drawable is wrong. The same problem happens when I go into landscape mode and scroll around. If I scroll down, up, the down again, the drawables are shuffled. For better illustration, let's say I have three objects, each with an image. Obj A shows an Apple Obj B shows a Banana Obj C shows a Cantaloupe When the shift occurs I end up with: Obj A shows an Cantaloupe Obj B shows a Banana Obj C shows a Apple The problem isn't consistent between the two causes (search dialog and screen rotate n' scroll), but each cause itself is consistent. Scrolling around repeatedly reveals a pattern as does the search dialog appearing. How can I stop this from happening?

  • SharpDevelop WIX project: MSBuild Configurations

    - by chezy525
    Using SharpDevelop, I wrote a windows service with a WIX setup project to install/auto-start it. For testing purposes, I've done a number of things I don't want to do in the release version (i.e. add an uninstall shortcut to the desktop). So, my question really boils down to this; how do you handle build configurations within a WiX project? I think I've solved most of my problems after I found this question Passing build parameters to .wxs file to dynamicaly build wix installers. And thus far I've done the following: Added a property that checks the Configuration variable <Product> ... <Property Id="DEBUG">$(var.Configuration) == 'Debug'</Property> ... Separated all of the debug files into unique components and setup as a separate feature with a condition checking the DEBUG property. <Product> ... <Feature> ... <Feature Id="DebugFiles" Level="1"> <ComponentRef Id="UninstallShortcutComponent" /> <Condition Level="0">DEBUG</Condition> </Feature> ... Then, finally, pointing to the correct file based on the configuration, using the Configuration variable <Directory> ... <Component> <File Source="..\mainProject\bin\$(var.Configuration)\main.exe" /> </Component> ... So, now my question is simplified to how to handle files that may not exist under certain build configurations (like .pdb files). Using all of the above (including pointing the file source to the ...\bin\Release\*.pdb, which I know isn't expected to exist) I get a LGHT0103 compiler error, it can't find the file.

  • VB.NET - Convert Unicode in one TB to Shift-JIS in another TB

    - by Yiu Korochko
    Trying to develop a text editor, I've got two textboxes, and a button below each one. When the button below textbox1 is pressed, it is supposed to convert the Unicode text (intended to be Japanese) to Shift-JIS. The reason why I am doing this is because the software VOCALOID2 only allows ANSI and Shift-JIS encoding text to be pasted into the lyrics system. Users of the application normally have their keyboard set to change to Japanese already, but it types in Unicode. How can I convert Unicode text to Shift-JIS when SJIS isn't available in the System.Text.Encoding types?

  • How can one close html tags in vim quickly

    - by wds
    It's been a while since I've had to do any html-like code in vim, but recently I came across this again. Say I'm doing a simple bit of a html page: <html><head><title>This is a title</title></head></html> How do I write those closing tags for title, head and html down quickly? I feel like I'm missing some really simple way here that does not involve me going through writing them all down one by one. Of course I can use ^P to autocomplete the individual tag names but what gets me on my laptop keyboard is actually getting the brackets and slash right.

  • Does Windows 7 have a Kiosk Mode?

    - by Jordan
    I'm writing a Kiosk on a Windows 7 computer. The Kiosk is on a touch screen computer, that will not have a keyboard. The application is a WPF application running the .NET Framework version 3.5. I'm having problems with the progress bar task bar showing up (blinking) at the bottom of the screen. This unfortunately gives the user access to the background operating system. Is there someway to lock a full screen application window into the front of the screen without using it on-top-of-everything mode. Some sort of Kiosk mode, or some tool that was designed for this.

  • presentModalViewController NOT animating when showing a TTMessageController

    - by wgpubs
    I have a subclass of TTMessageController that shows ... BUT it is not animated even though it should be. The code that displays the modal view looks like this (where PostToWebMessageController is the subclass of TTMessageController: if (self.toWebMsgController == nil) { self.toWebMsgController = [[PostToWebMessageController alloc] init]; } UINavigationController *navController = [[UINavigationController alloc] init]; [navController pushViewController:self.toWebMsgController animated:NO]; [self presentModalViewController:navController animated:YES]; What happens though is this: The screen goes black ... the keyboard scrolls up into view ... and THEN the TTMessageController view shows up (not animated). When I dismiss the view via a Cancel button the screen goes black and then just disappears (no animation again). Any ideas why this is happening? I've this with a number of other TT* controllers and I can't get one to animate right with showing modally. Thanks

  • Using numeric values to select item from a dropdown box with JavaScript

    - by Shyam
    Hi, I have a multitude of dropdown boxes within my webpage. One of these dropdown boxes is used for a single selected value out of a list of options. <SELECT id="Box0" name=""> <OPTION value="0">none</OPTION> <OPTION value="1">first</OPTION> <OPTION value="2">second</OPTION> </SELECT> How can I add an event to this section, so when it is in focus, I could use numeric keys like 1,2.. to select an option instead of using the mouse or arrow keys for selecting an option? For clarification: if I press "1" on my keyboard, the selected value would become "first", with "2" the selected value becomes "second". I choose not to use a library/framework such as JQuery/Mootools. Thanks,

  • check external website registration

    - by Arsenal
    Hi, I'm trying to create a PHP based game where you have to do all sorts of simple but un-obvious tasks in order to progress to the next level (eg. refresh browser, press keyboard combination, ...) Kinda like the game "this is the only level" (if anyone has ever heard of it) Now I was thinking: Would it be possible to create a level where they'd have to sign up at a different page in order to progress to the next level? So say for example they need to sign up to goal.com and if they're signed up they proceed to the next level. The page would need to constantly check if the signup process on the other site is completed. Is this even possbible? And if so, any thoughts on how? Thanks!

  • Turn off the display on remote PC

    - by concretemixer
    Hello. I'm fixing some bugs in the application for remote control (remote desktop-like) for Windows. And there is a feature that you can blank screen on remote machine - all the programms keep running unaffected, but the person who looks into the display on remote PC sees nothing but black screen. It is implemented by sending IoCtl request IOCTL_VIDEO_SET_OUTPUT_DEVICE_POWER_STATE, which is undocumented. And this request does not work on Vista and above. Are there another ways to do what I want? In fact, SendMessage(-1,WM_SOMMAND,SC_MONITORPOWER,2) does the trick, but screen turns back on if someone toches keyboard/mouse.

  • Loading dictionary for input method suggestion list

    - by jpspringall
    Hi, For various reasons, i'm trying to write my own input keyboard. So far all is going well except that of creating the suggestions. I've found the latinIME algorithm, which is all good. However i'm having major difficulty working out how to load the dictionary in the first place. I've had a good look round the net, and found various suggestions, but no definitive answers, and i cant seem to get any of them to work. If anyone has any suggestions on how best to do it, or even better some sample code, that would be brilliant. Many Thanks James

  • Best anti boss tricks to hide your private page navigation from your desktop.

    - by systempuntoout
    This question is slightly related to programming and it's kinda lame, i know; but i saw many funny things in these years and i'm looking for new tricks from you. I'm talking about methods to fast-hide\camouflage not job related web pages on your desktop when boss arrives like a ghost\ninja behind your shoulders. I know how much can be frustrating, programming hard for ten hours and then been caught by your boss watching XKCD during a 2 minutes break. I think the most common anti boss trick is the evergreen CTRL+TAB, but you have to be fast and your left hand has to be near the keyboard. I saw pitch black brightness on Lcd (how can you pretend to program on that?) or custom sized browser to fit a little space just below the IDE. My favourite one at the moment is using fire gesture plugin with FF; with a micro gesture you can hide FF to your tray in a blink of an eye. Do you have any trick to share?

  • Using tab key to navigate google search results

    - by CrazyJugglerDrummer
    Google the phrase "Humans vs zombies" (just used for an example here, phrase doesn't matter). When you see the search results, put your fingers on the keyboard, and press tab until you get to the first result. It takes me over 10 tabs to get through the "images", "videos", "maps", "advanced search" and other links. (Do you get the same results?) How can I get it so pressing the tab key the first time takes me to the first link? I'm using FF 3.6. How might I be able to greasemonkey this?

  • Vim - show diff on commit in mercurial;

    - by JackLeo
    In my .hgrc I can provide an editor or a command to launch an editor with options on commit. I want to write a method or alias that launches $ hg ci, it would not only open up message in Vim, but also would split window and there print out $ hg diff. I know that I can give parameters to vim by using +{command} option. So launching $ vim "+vsplit" does the split but any other options goes to first opened window. So I assume i need a specific function, yet I have no experience in writing my own Vim scripts. The script should: Open new vertical split with empty buffer (with vnew possibly) In empty buffer launch :.!hg diff Set empty buffer file type as diff :set ft=diff I've written such function: function! HgCiDiff() vnew :.!hg diff set ft=diff endfunction And in .hgrc I've added option: editor = vim "+HgCiDiff()" It kind of works, but I would like that splited window would be in right side (now it opens up in left) and mercurial message would be focused window. Also :wq could be setted as temporary shortcut to :wq<CR>:q! (having an assumption that mercurial message is is focused). Any suggestions to make this a bit more useful and less chunky? UPDATE: I found vim split guide so changing vnew with rightbelow vnew opens up diff on the right side.

  • Are Tuples a poor design decision in C#?

    - by Jason Webb
    With the addition of the Tuple class in .net 4, I have been trying to decide if using them in my design is a bad choice or not. The way I see it, a Tuple is a shortcut to writing a result class (I am sure there are other uses too). So this: public class ResultType { public string StringValue { get; set; } public int IntValue { get; set; } } public ResultType GetAClassedValue() { //..Do Some Stuff ResultType result = new ResultType { StringValue = "A String", IntValue = 2 }; return result; } Is equivalent to this: public Tuple<string, int> GetATupledValue() { //...Do Some stuff Tuple<string, int> result = new Tuple<string, int>("A String", 2); return result; } So setting aside the possibility that I am missing the point of Tuples, is the example with a Tuple a bad design choice? To me it seems like less clutter, but not as self documenting and clean. Meaning that with the type ResultType, it is very clear later on what each part of the class means but you have extra code to maintain. With the Tuple<string, int> you will need to look up and figure out what each Item represents, but you write and maintain less code. Any experience you have had with this choice would be greatly appreciated.

  • Creating a Ruby method that pads an Array

    - by CJ Johnson
    I'm working on creating a method that pads an array, and accepts 1. a desired value and 2. an optional string/integer value. Desired_size reflects the desired number of elements in the array. If a string/integer is passed in as the second value, this value is used to pad the array with extra elements. I understand there is a 'fill' method that can shortcut this - but that would be cheating for the homework I'm doing. The issue: no matter what I do, only the original array is returned. I started here: class Array def pad(desired_size, value = nil) desired_size >= self.length ? return self : (desired_size - self.length).times.do { |x| self << value } end end test_array = [1, 2, 3] test_array.pad(5) From what I researched the issue seemed to be around trying to alter self's array, so I learned about .inject and gave that a whirl: class Array def pad(desired_size, value = nil) if desired_size >= self.length return self else (desired_size - self.length).times.inject { |array, x| array << value } return array end end end test_array = [1, 2, 3] test_array.pad(5) The interwebs tell me the problem might be with any reference to self so I wiped that out altogether: class Array def pad(desired_size, value = nil) array = [] self.each { |x| array << x } if desired_size >= array.length return array else (desired_size - array.length).times.inject { |array, x| array << value } return array end end end test_array = [1, 2, 3] test_array.pad(5) I'm very new to classes and still trying to learn about them. Maybe I'm not even testing them the right way with my test_array? Otherwise, I think the issue is I get the method to recognize the desired_size value that's being passed in. I don't know where to go next. Any advice would be appreciated. Thanks in advance for your time.

  • JQuery Autocomplete - Stop mouseover+Return submitting data

    - by ILT
    I'm using JQuery Autocomplete (bassistance) and have run into a problem. If the mouse rolls over one of the autocomplete suggestions and the user hits the return key (rather than clicking to make selection), the form is submitted and goes to whatever link was rolled over at the time. This is a problem as people click in the textbox, and when typing their search, leave the pointer where the autocomplete popup appears. So when they hit enter, it doesn't do the search for whatever they typed in the box but whatever was highlighted in the autocomplete suggestions. Is there a way to stop this? Using Google as the functionality I'm after... So just to clarify - I want selections via mouse and keyboard to go to the same place, but if the UP or DOWN arrow has not been pressed (user not selected an autocomplete option via the keyword), dont go to the URL specified in the autosuggest - instead submit the form (traditional method without JQuery) based on what has been typed in the textbox. I hope I'm explaining this clearly? :S

  • How to get or make a WPF WebBrowser with a visual.

    - by Trainee4Life
    Having problems related to WPF WebBrowser not having a visual. Reason being, that it actually a wrapper around the winforms browser. Anyways, I searched the web for any solution to this problem, and got hold of the following suggestions: http://chriscavanagh.wordpress.com/2009/08/25/a-real-wpf-webbrowser/ http://rob.runtothehills.org/archives/60 The first one solves everything, but seems like an overkill. Plus, the dll's should be licensed for commercial use. The second one seems simple, but not able to figure out when to refresh the screen. Plus there's so much to do like sending mouse and keyboard messages to the webbrowser. P.S. The problem I'm trying to solve is to show the same webbrowser on different windows. They both must be interactive, and always in sync visually.

  • CLI design and implementation?

    - by Majid
    I am developing a time management tool for my personal use. I prefer using keyboard over mouse, and on the interface have a general purpose text box which will act like a command line. I have just started thinking about what commands I need, what to use for the command names, how to pass in switches and parameters, and so forth. I wonder if some of you have come across a good read along these lines; something that describes the choices you have for designing a cli, and how those affect the complexity of the interpreter, and extendability of the commands. It makes no difference if the descriptions are language-specific or in general terms. However, my implementation will be with javascript. Thank you.

  • Simple Emacs keybindings

    - by User1
    I have two operations that I do all the time in Emacs: Create a new buffer and paste the clipboard. [C-S-n] Close the current buffer. [C-S-w] Switch to the last viewed buffer [C-TAB] I feel like a keyboard acrobat when doing the first two operations. I think it would be worth trying some custom keybindings and macros. A few questions about this customization: How would I make a macro for #1? Are these good keybindings (i know this is a bit subjective, but they might be used by something popular that I don't use) Has anyone found a Ctrl-Tab macro that will act like Alt-Tab in Linux/Windows? Specifically, I want it have a stack of buffers according to the last viewed timestamp (most recent on top). I want to continue cycling through the stack until I let go of the ctrl key. When the ctrl key is released, I want the current buffer to get an updated position on the stack.

  • Oracle Forms 6i master-detail question from a painfully new newbie

    - by Murasaki
    Hello, I have a form that contains 3 blocks (block a, b, c). There is a master-detail relationship between b (detail) and c (master). Data-flow: you enter an ID in block a, which in turn populates block c and corresponding details in block b. Control goes immediately to block c. Objective: I need to be able to update details of block b. Issue: I cannot navigate to block b. Keep in Mind: --In the Property Palette Keyboard Navigable is set to "Yes" --Insert Allowed and Update Allowed are set to "Yes." If someone could respond ASAP I would really appreciate it. Thank you.
