  • VB.NET Window Screen Capture (ALT+PRINTSCREEN)

    - by Steve Thomas
    Hi, I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it. Here is the code that works for full Screen Capture Private bmpScreenShot As Bitmap Private gfxScreenshot As Graphics bmpScreenShot = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb) gfxScreenshot = Graphics.FromImage(bmpScreenShot) gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy) bmpScreenShot.Save(fileName, ImageFormat.Png) I use the Visual Basic 2008 Express Thank you in advance!

  • Prolog: Finding the Nth Element in a List

    - by Thomas
    I am attempting to locate the nth element of a List in Prolog. Here is the code I am attempting to use: Cells = [OK, _, _, _, _, _] . ... next_safe(_) :- facing(CurrentDirection), delta(CurrentDirection, Delta), in_cell(OldLoc), NewLoc is OldLoc + Delta, nth1(NewLoc, Cells, SafetyIdentifier), SafetyIdentifier = OK . Basically, I am trying to check to see if a given cell is "OK" to move into. Am I missing something?

  • Is there a table of OpenGL extensions, versions, and hardware support somewhere?

    - by Thomas
    I'm looking for some resource that can help me decide what OpenGL version my game needs at minimum, and what features to support through extensions. Ideally, a table of the following format: 1.0 1.1 1.2 1.2.1 1.3 ... multitexture - ARB ARB core core texture_float - EXT EXT ARB ARB ... (Not sure about the values I put in, but you get the idea.) The extension specs themselves, at opengl.org, list the minimum OpenGL version they need, so that part is easy. However, many extensions have been accepted and became core standard in subsequent OpenGL versions, but it is very hard to find when that happened. The only way I could find is to compare the full OpenGL standards document for each version. On a related note, I would also very much like to know which extensions/features are supported by which hardware, to help me decide what features I can safely use in my game, and which ones I need to make optional. For example, a big honkin' table like this: MAX_TEXTURE_IMAGE_UNITS MAX_VERTEX_TEXTURE_IMAGE_UNITS ... GeForce 6xxx 8 4 GeForce 7xxx 16 8 ATi x300 8 4 ... (Again, I'm making the values up.) The table could list hardware limitations from glGet but also support for particular extensions, and limitations of such extension support (e.g. what floating-point texture formats are supported in hardware). Any pointers to these or similar resources would be hugely appreciated!

  • using usort to re-arrange multi-dimension array

    - by Thomas Bennett
    I have a large array: [0] => stdClass Object ( [products] => Array ( [0] => stdClass Object ( [body_html] => bodyhtml [published_at] => 2012-12-16T23:59:18+00:00 [created_at] => 2012-12-16T11:30:24+00:00 [updated_at] => 2012-12-18T10:52:14+00:00 [vendor] => Name [product_type] => type ) [1] => stdClass Object ( [body_html] => bodyhtml [published_at] => 2012-12-16T23:59:18+00:00 [created_at] => 2012-12-16T10:30:24+00:00 [updated_at] => 2012-12-18T10:52:14+00:00 [vendor] => Name [product_type] => type ) ) ) and I need to arrange each of the products by the date they where created... I've tried and failed all kinds of usort, ksort, uksort techniques to try and get it to be in a specific order (chronological) but failed! any guidance would be most appreciated

  • Named parameters lead to inferior readability?

    - by Thomas Jung
    With named parameters like def f(x : Int = 1, y : Int = 2) = x * y your parameter names become part of the interface f(x=3) Now if you want to change the parameter names locally, you are forced to perserve the public name of the parameter: def f(x : Int = 1, y : Int = 2) = { val (a,b) = (x,y) a * b } If this a real problem? Is there a syntax to support this directly? Who do other languages handle this?

  • How do you use stl's functions like for_each?

    - by thomas-gies
    I started using stl containers because they came in very handy when I needed functionality of a list, set and map and had nothing else available in my programming environment. I did not care much about the ideas behind it. STL documentations were only interesting up to the point where it came to functions, etc. Then I skipped reading and just used the containers. But yesterday, still being relaxed from my holidays, I just gave it a try and wanted to go a bit more the stl way. So I used the transform function (can I have a little bit of applause for me, thank you). From an academic point of view it really looked interesting and it worked. But the thing that boroughs me is that if you intensify the use of those functions, you need 10ks of helper classes for mostly everything you want to do in your code. The hole logic of the program is sliced in tiny pieces. This slicing is not the result of god coding habits. It's just a technical need. Something, that makes my life probably harder not easier. And I learned the hard way, that you should always choose the simplest approach that solves the problem at hand. And I can't see what, for example, the for_each function is doing for me that justifies the use of a helper class over several simple lines of code that sit inside a normal loop so that everybody can see what is going on. I would like to know, what you are thinking about my concerns? Did you see it like I do when you started working this way and have changed your mind when you got used to it? Are there benefits that I overlooked? Or do you just ignore this stuff as I did (and will go an doing it, probably). Thanks. PS: I know that there is a real for_each loop in boost. But I ignore it here since it is just a convenient way for my usual loops with iterators I guess.

  • Restoring using SyncBack without profiles

    - by Thomas Matthews
    I backed up my internal hard drive (C:) using SyncBack onto an external (USB) hard drive with maximum compression. I then performed a clean install of Windows Vista onto the computer. I forgot to copy the SyncBack logs before the clean install. And now when ever I try to restore a directory, the RAR/ZIP files are copied to the system hard drive instead of extracting their contents to the hard drive. Also, SyncBack is not traversing the folders during the Restore process. How can I tell SyncBack to expand the compressed files? I am running the freeware version of SyncBack. I have to create new log files (unless SyncBack put them somewhere on the external drive). My alternative is to write a program that traverses the folders on the external drive and extracts files from the RAR/ZIP files. I am using Windows Vista, Service Pack 2, and the data size prior to backup was about 200 GB. (The backup process took over 72 hours due to "hiccups").

  • How to animate a UIButton selected background Image

    - by Thomas Joos
    hi all, I have a class defining a custom UIButton. I configurate a normal and selected state like this: //custom image UIImage *image = [UIImage imageNamed:@"customIconCreationBG.png"]; UIImage *stretchImage = [image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImage forState:UIControlStateNormal]; UIImage *imageSelected = [UIImage imageNamed:@"customIconCreationBG_selected.png"]; UIImage *stretchImageSelected = [imageSelected stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImageSelected forState:UIControlStateSelected]; In another class I'm filling an array with custom buttons and i'm adding a button pressed method. It sets the selected state to TRUE -(void)buttnPressed:(id)sender { NSLog(@"button pressed"); [[NSNotificationCenter defaultCenter] postNotificationName:@"unselectBGIcons" object:self]; HorizontalListIcon *pressedIcon = ((HorizontalListIcon *)sender); [pressedIcon setSelected:TRUE]; } The button switches to another background, which is great. Is there a way to animate this change ( fading in? ) because it's a bit hard now. Greets

Sorry!"; else echo "The domain name is available!"; } ?> I want my php code to process the text input and say if it's a valid domain or not. The only thing that doesn't work is linking the input to the php.

  • How to make the TextView invisible when there are items in listView?

    - by Raphael Thomas Liewl
    I like to display textView when there are no items in the listView whereas the textView will not display when there are items in the listView. My problem is even there are items in the listView, the textView still will be displayed in a short time and then load the items into listView. So, how to make the TextView invisible when there are items in listView? Here is the codes: public void onCreate(Bundle savedInstancesState){ super.onCreate(savedInstancesState); setContentView(R.layout.list_screen); user = getIntent().getExtras().getString("user"); Log.d("dg",user); getList(); lv = (ListView) findViewById(android.R.id.list); emptyText = (TextView)findViewById(android.R.id.empty); lv.setEmptyView(emptyText); } list_screen.xml <?xml version="1.0" encoding="UTF-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:id="@+id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <TextView android:id="@+id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/no_friend" android:gravity="center_vertical|center_horizontal"/> </LinearLayout>

  • Using Memcached in Python/Django - questions.

    - by Thomas
    I am starting use Memcached to make my website faster. For constant data in my database I use this: from django.core.cache import cache cache_key = 'regions' regions = cache.get(cache_key) if result is None: """Not Found in Cache""" regions = Regions.objects.all() cache.set(cache_key, regions, 2592000) #(2592000sekund = 30 dni) return regions For seldom changed data I use signals: from django.core.cache import cache from django.db.models import signals def nuke_social_network_cache(self, instance, **kwargs): cache_key = 'networks_for_%s' % (self.instance.user_id,) cache.delete(cache_key) signals.post_save.connect(nuke_social_network_cache, sender=SocialNetworkProfile) signals.post_delete.connect(nuke_social_network_cache, sender=SocialNetworkProfile) Is it correct way? I installed django-memcached-0.1.2, which show me: Memcached Server Stats Server Keys Hits Gets Hit_Rate Traffic_In Traffic_Out Usage Uptime 127.0.0.1 15 220 276 79% 83.1 KB 364.1 KB 18.4 KB 22:21:25 Can sombody explain what columns means? And last question. I have templates where I am getting much records from a few table (relationships). So in my view I get records from one table and in templates show it and related info from others. Generating page last a few seconds for very small table (<100records). Is it some easy way to cache queries from templates? Have I to do some big structure in my view (with all related tables), cache it and send to template?

  • Does an open source project need a news group?

    - by Daren Thomas
    I open-sourced a tool I created to scratch an itch. From the downloads for the installer on the project page I can see I'm not the only one interested. About 5 people seem to have upgraded from the previous version. But I know next to nothing about them. Do I need a news group? A mailing list? Or how would you start to build a (little) community?

  • How do I find the screen size in a fragment class

    - by thomas.cloud
    I was looking at this posting: Android: How to get screen dimensions when I was trying to determine the size of the device's screen while in a fragment class. One answer was close to what I needed but the only code that ended up working for me was: WindowManager wm = (WindowManager) getView().getContext().getSystemService(Context.WINDOW_SERVICE); Display screen = wm.getDefaultDisplay(); whereupon I could then use getHeight(); or another non-deprecated term. I realize this is exactly the same as the other site except this way you don't have define your context on a separate line.

  • ASP.Net Vertical Menu with Scroll functionality

    - by Thomas
    Referring to Menu / Scrolling Example I would like to create / find the same functionality for a vertical menu. I tried the following. <asp:Menu ID="menuAccountMembers" runat="server" StaticSubMenuIndent="16px" Visible="true" RenderingMode="Table" ScrollDownImageUrl="~/Resources/scrolldown.jpg" ScrollUpImageUrl="~/Resources/scrollup.jpg"> <Items> But it doesnt display any scrolling images. I am using .net 4.0 Tried setting menuAccountMembers.RenderingCompatibility = new Version(3, 5); as well. If there a property to only display the first 5 root menu items, then show scroll bars for the rest? It can be click-able, no need to hover over to show next item.

  • Setting the content-type of a response in Struts2

    - by Thomas
    So, I'm using freemarker templates with Struts2 to formulate my responses. However, since I'm trying to use taconite as well, I need the response to be sent with the content type of "text/xml". I can't seem to find a way to use freemarker directives to set the content type, and I am not well versed enough in struts to know if there is a way to do it through that. So, how should I go about this?
