  • Strange issue with fixed form border styles in Vista

    - by Nazgulled
    My previous post about this issue didn't got too many answers and it was kinda specific and hard to understand. I think I've managed to understand the problem better and I now believe it to be a Vista issue... The problem lies on all types of fixed border styles like FixedDialog, Fixed3D, FixedSingle and FixedToolWindow. It does not happen on the sizable ones. This problem, like I said, it also happens only on Vista. Let's say you have a form with any of the fixed border styles and set the starting location to 0,0. What you want here is for the form to be snapped to the top left corner of the screen. This works just fine if the form border style is one of the sizable options, if it's fixed, well, the form will be a little bit outside of the screen working area both to the left and top. What's more strange about this is that the form location does not change, it sill is 0,0, but a few pixels of the form are still drawn outside of the working screen area. I tested this on XP and it didn't happen, the problem is Vista specific. On XP, the only difference was the border size that change a bit between any of the styles. But the form was always perfectly snapped to position 0,0. If possible, without finding how many pixels are being drawn outside of the working area and then add that to the form location, is there a possible way to fix or workaround this?

  • How do I implement a group of strings that starts randomly, but is bound by relevance upon selection?

    - by Freakishly
    Okay the title may be a little confusing, but here's what I'm trying to do :) I have a game in XNA where every tap from the user draws a moving circle on the screen. The circle has a tag, say 'dogs' displayed on it. So imagine multiple taps on the screen, and we have all these circles of various colors and sizes moving around the screen with different (but constant) velocities. Each circle with different tags: 'dogs', 'cats' and so on... Clicking on empty space generates a new circle at that point. Clicking on one of the circles "selects" it, turning it into a greeen shade and slowing its velocity down to a fraction of what it was. Clicking on it again "unselects" it, and restores its original color and velocity (trajectory does not change). With each circle comes a tag, and as of now I'm populating these tags randomly from a string array (which means there's a chance tags will repeat). I would like the tags for newly created circles to be relevant to previous "selected" tags. So when I click on 'dogs', I would like 'German Shepherd' but I would also like 'dog parks' and 'lemurs' assuming dogs get along well with lemurs. What would be the best way to approach this problem. In my head I have a massive many-to-many mapping, but I can't seem to translate it to code. Thanks for looking. FYI I'm using the sample project from here: http://mobile.tutsplus.com/tutorials/windows/introduction-to-xna-on-windows-phone-7/

  • efficiently finding the interval with non-zeros in scipy/numpy in Python?

    - by user248237
    suppose I have a python list or a python 1-d array (represented in numpy). assume that there is a contiguous stretch of elements how can I find the start and end coordinates (i.e. indices) of the stretch of non-zeros in this list or array? for example, a = [0, 0, 0, 0, 1, 2, 3, 4] nonzero_coords(a) should return [4, 7]. for: b = [1, 2, 3, 4, 0, 0] nonzero_coords(b) should return [0, 2]. thanks.

  • Using CreateOrthographicOffCenter in XNA

    - by Jeffrey Kern
    I'm trying to figure out how to draw graphics in XNA, and someone else suggested this. But before I attempt to use this... If I create and use this camera, and set LEFT,TOP to 0 and WIDTH=256 and HEIGHT=240, anything I render to the screen will use these coordinates? So a box with a width and height of 1, if set to 0,0 will take up space from 0,0 to 1,1?

  • Getting empty update rectangle in OnPaint after calling InvalidateRect on a layered window

    - by Shawn
    I'm trying to figure out why I've been getting an empty update rectangle when I call InvalidateRect on a transparent window. The idea is that I've drawn something on the window (it gets temporarily switched to have an alpha of 1/255 for the drawing), and then I switch it to full transparent mode (i.e. alpha of 0) in order to interact with the desktop & to be able to move the drawing around the screen on top of the desktop. When I try to move the drawing, I get its bounding rectangle & use it to call InvalidateRect, as such: InvalidateRect(m_hTarget, &winRect, FALSE); I've confirmed that the winRect is indeed correct, and that m_hTarget is the correct window & that its rectangle fully encompasses winRect. I get into the OnPaint handler in the class corresponding to m_hTarget, which is derived from a CWnd. In there, I create a CPaintDC, but when I try to access the update rectangle (dcPaint.m_ps.rcPaint) it's always empty. This rectangle gets passed to a function that determines if we need to update the screen (by using UpdateLayeredWindow in the case of a transparent window). If I hard-code a non-empty rectangle in here, the remaining code works correctly & I am able to move the drawing around the screen. I tried changing the 'FALSE' parameter to 'TRUE' in InvalidateRect, with no effect. I also tried using a standard CDC, and then using BeginPaint/EndPaint method in my OnPaint handler, just to ensure that CPaintDC wasn't doing something odd ... but I got the same results. The code that I'm using was originally designed for opaque windows. If m_hTarget corresponds to an opaque window, the same set of function calls results in the correct (i.e. non-empty) rectangle being passed to OnPaint. Once the window is layered, though, it doesn't seem to work right.

  • Is there a way to detect Layout or Display changes in WPF?

    Hello! I am trying to check how fast the Frame control can display a FixedPage object when it is assigned to Frame.Content property. I plan to check the tick count before and after the assignment to the Content property. Example: int starttime = Environment.TickCount; frame1.Content = fixedpage; int endtime = Environment.TickCount; The problem is that the assignment to the Content property might be asynchronous and returns immediately therefore i get a zero amount of time. The rendering of the FixedPage however visually has a lag time from assignment of the Content property up to the point where the FixedPage appears on screen. The Frame.ContentChanged() event is no good either because it gets triggered even before the FixedPage appears on screen so it's not accurate. I'm thinking of detecting the change on the window or control's display instead in order to get the time when the FixedPage is actually displayed on screen. Is there a way to do this in WPF? Thanks!

  • Problem inserting Pygames on a wxPython panel using Boa Constructor

    - by Kohwalter
    Hello, im new in Python so im hoping to to get some help to figure out what is going wrong. Im trying to run a Pygames from within wxPython panel (made on Boa Constructor). To do that i followed the instructions on the http://wiki.wxpython.org/IntegratingPyGame but still it isn't working. Here is the Panel code that was used to make the integration: class PG_panel(wx.Panel): def __init__(self, ID, name, parent, mypos, mysize): # pygame is imported in this class # make it globally available global pygame #self.Fit() wx.Panel.__init__(self, id=wxID_FRMMAINPANELTABULEIRO, name='panelTabuleiro', parent=self, pos=(16, 96), size=mysize) # pygame uses SDL, set the environment variables os.environ['SDL_WINDOWID'] = str(self.GetHandle()) os.environ['SDL_VIDEODRIVER'] = 'windib' # do the pygame stuff after setting the environment variables import pygame pygame.display.init() # create the pygame window/screen screen = pygame.display.set_mode(464, 464) #(424,450) # start the thread instance self.thread = PG_thread(screen) self.thread.start() def __del__(self): self.thread.stop() And im trying to use that panel on an interface from Boa Constructor, here is the code: class frmMain(wx.Frame): def _init_ctrls(self, prnt): # generated method, don't edit wx.Frame.__init__(self, id=wxID_FRMMAIN, name='frmMain', parent=prnt, pos=wx.Point(660, 239), size=wx.Size(815, 661), style=wx.DEFAULT_FRAME_STYLE, title='Grupo 1 - Jogo de Damas') self._init_utils() self.SetClientSize(wx.Size(799, 623)) self.SetBackgroundColour(wx.Colour(225, 225, 225)) self.SetMinSize(wx.Size(784, 650)) self.Center(wx.BOTH) self.SetMenuBar(self.menuBar1) #here begins my code mysize = (464, 464) mypos = (16, 96) self.panelTabuleiro = PG_panel(wxID_FRMMAINPANELTABULEIRO, 'panelTabuleiro', self, mypos, mysize) The original that was auto-made by the Boa Constructor is the following: self.panelTabuleiro = wx.Panel(id=wxID_FRMMAINPANELTABULEIRO, name='panelTabuleiro', parent=self, pos=wx.Point(16, 96), size=wx.Size(464, 464), style=wx.TAB_TRAVERSAL) self.panelTabuleiro.SetBackgroundColour(wx.Colour(232, 249, 240)) self.panelTabuleiro.SetThemeEnabled(True) self.panelTabuleiro.SetHelpText('Tabuleiro') The error that it gives is: Type error: in method 'new_Panel', expected argument 1 of type 'wxWindow*1 Exception AttributeError: "'PG_panel' object has no attribute 'thread' in ignored Any thoughts ? I appreciate any help. Thank you.

  • How to cancel a touch sequence

    - by Alex
    I have an UIImage view that responds to touch events. I want to cancel the touch sequence if the touch goes outside of certain bounds. How can I do that? I know that I can inspect the coordinates of the touch object, what I don't know is how to cancel the sequence. I don't see any event in the API that allows for that.

  • Replace ",**" with a linebreak using RegEx (or something else)

    - by John
    I'm getting started with RegEx and I was wondering if anyone could help me craft a statement to convert coordinates as follows: 145.00694,-37.80421,9 145.00686,-37.80382,9 145.00595,-37.8035,16 145.00586,-37.80301,16 to 145.00694,-37.80421 145.00686,-37.80382 145.00595,-37.8035 145.00586,-37.80301 (Strip off the last comma and value and turn it into a line break.) I can't figure out how to use wildcards to do something like that. Any help would be greatly appreciated! Thanks.

  • circles and triangles problem

    - by Faken
    Hello everyone, I have an interesting problem here I've been trying to solve for the last little while: I have 3 circles on a 2D xy plane, each with the same known radius. I know the coordinates of each of the three centers (they are arbitrary and can be anywhere). What is the largest triangle that can be drawn such that each vertice of the triangle sits on a separate circle, what are the coordinates of those verticies? I've been looking at this problem for hours and asked a bunch of people but so far only one person has been able to suggest a plausible solution (though i have no way of proving it). The solution that we have come up with involves first creating a triangle about the three circle centers. Next we look at each circle individually and calculate the equation of a line that passes through the circle's center and is perpendicular to the opposite edge. We then calculate two intersection points of the circle. This is then done for the next two circles with a result of 6 points. We iterate over the 8 possible 3 point triangles that these 6 points create (the restriction is that each point of the big triangle must be on a separate circle) and find the maximum size. The results look reasonable (at least when drawn out on paper) and it passes the special case of when the centers of the circles all fall on a straight line (gives a known largest triangle). Unfortunate i have no way of proving this is correct or not. I'm wondering if anyone has encountered a problem similar to this and if so, how did you solve it? Note: I understand that this is mostly a math question and not programming, however it is going to be implemented in code and it must be optimized to run very fast and efficient. In fact, I already have the above solution in code and tested to be working, if you would like to take a look, please let me know, i chose not to post it because its all in vector form and pretty much impossible to figure out exactly what is going on (because it's been condensed to be more efficient). Lastly, yes this is for school work, though it is NOT a homework question/assignment/project. It's part of my graduate thesis (abet a very very small part, but still technically is part of it). Thanks for your help.

  • matplotlib - changing rect colours on the fly

    - by Nick
    I am playing with matplotlib - I have a bar chart, and I want to highlight the bar which user clicks. I have a callback that goes through a rect collection (the one I got from self.axis.bar(...)) and finds out which one was clicked (looking at the coordinates). At this point I want to call something to change the colour of the current bar. Is it possible? How do I do that?

    I have built an application in CakePHP that lists businesses. There are about 2000 entries, and the latitude and longitude coordinates for each business is in the DB. I now am trying to tackle the search function. There will be an input box where the user can put a street address, city, or zipcode, and then I would like it to return the 11 closest businesses as found from the database. How would I go about doing this?

  • AsyncTask never finishes when other tasks are running

    - by rebeccamaher
    In my app, I show a menu screen immediately to the user and then use an AsyncTask to load some data from disk. Loading takes about 3 seconds if that's all the app had to do. When the user hits a menu option and the data hasn't loaded yet, a "Please wait, loading" screen appears. I have two problems: I recently added ads to my app and have found this is making my app hang sometimes because the AsyncTask never finishes loading. What seems to be happening is that the ad banner (I'm using admob and this happens when adsense ads are shown which admob do occasionally) is using resources by playing a simple animation and the AsyncTask never gets a chance to finish. I want to play a simple looping animation (e.g. making a view rotate) on my menu screen and this makes the AsyncTask take about 5 times longer to finish which renders the background loading pointless. How can I avoid situations where my background data never finishes loading or has such a low priority it takes a long time? I can't seem to find a way to increase the priority of an AsyncTask.

  • How can you track mouse input using the fewest libraries in c.

    - by TimE
    I'm not sure where to look to find this information, but I'd like to know how to get mouse input (or any hid input) using the fewest non standard libraries in c. Basically, is there an stdio equivalent for mouse (and other input) input in c? Or is there a library that is minimal and cross compatible on multiple platforms. Just being able to print mouse coordinates to a terminal window would be enough.

  • On android how would I go about creating a prompt for an app that requires a user to enter a username before fully launching the app?

    - by racl101
    I'll preface this with I'm really new to working on Android. So I have to work on an existing app and create a screen that prompts the user for a username if one isn't entered then it won't launch the currently existing main activity (i.e. it won't fully launch the app. Instead it will just sit on that screen until a username is entered.) I suppose that it's tantamount to a web app login page in that it will not let a user past that page if the user is not authenticated and authorized. However, there's no authentication nor authorization in this app. Instead, on first run a user must simply register with a username and that username gets saved to the database and for any subsequent runs the app's main activity will just start because a user has registered to that phone. In fact, the app will not prompt the user for their name again unless the app gets deleted with all its data and reinstalled again. This implicitly means that I have to save the user's name in the database or some other kind of storage. So I was wondering what would be the best way of doing this in an app with an existing main activity? Should I try to accomplish this on that existing main activity or create a new activity to display this prompt screen and, in effect, block the main activity from running until the user enters their name? Any tutorials or links would be helpful and thank you in advance for any help.

  • jQueryUI dialog width

    - by user35295
    Fiddle Full Screen Example I use jQuery dialog to open tables. Some of them have a large amount of text and they tend to be too long and go way off the screen. How can I make the dialog wider if the table is too long like the first one in the fiddle? I've tried width:'auto' but it seems to just occupy the entire screen. HTML: <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> Javascript: $(document).ready(function(){ $('.label').each(function() { var dialogopen = $(this).next(".dialog"); dialogopen.dialog({width:'auto',autoOpen: false,modal: true, open: function(){ jQuery('.ui-widget-overlay').bind('click',function(){ dialogopen.dialog('close'); }) } }); $(this).click(function(){ dialogopen.dialog('open'); return false; } ); }); });
