  • Application for taking pretty screenshots (like OS X does)

    - by Oli
    I've been building a website for a guy who uses Mac OS X and occasionally he sends me screenshots of bugs. They come out looking like this: This is fairly typical of Mac screenshots. You get the window decorations, the shadow from the window and a white or transparent background (not the desktop wallpaper -- I've checked). Compare this to an Ubuntu window-shot (Alt+Print screen): It's impossible to keep a straight face and say the Ubuntu one anywhere near as elegant. My question is: Is there an application that can do this in Ubuntu? Edit: Follow up: Is there an application that can do this in one move? Shutter is pretty good but running the plugin for every screenshot is pretty tiresome as it doesn't seem to remember my preference (I want south-shadow and that requires selecting south, then clicking refresh, then save) and it's more clicks than I'd like. Is there a simple way of telling shutter I want south-shadow for all screenshots (except entire desktop and area-selection)?

    Cannot install vcrun6. I tried to do it with winetricks and manually (download vcredist.exe and install), but nothing. Launching in terminal gives the following _user@_user-machine:~$ WINEPREFIX="/home/_user/.wine" wine "C:/vcredist.exe" fixme:setupapi:SetupDefaultQueueCallbackW notification 262144 params 32f63c,0 err:setupapi:SetupDefaultQueueCallbackW copy error 0 L"C:\\users\\_user\\Temp\\IXP000.TMP\\comcat.dll" -> L"C:\\windows\\system32\\comcat.dll" fixme:setupapi:SetupDefaultQueueCallbackW notification 262144 params 32f63c,0 err:setupapi:SetupDefaultQueueCallbackW copy error 0 L"C:\\users\\_user\\Temp\\IXP000.TMP\\msvcrt.dll" -> L"C:\\windows\\system32\\msvcrt.dll" fixme:setupapi:SetupDefaultQueueCallbackW notification 262144 params 32f63c,0 err:setupapi:SetupDefaultQueueCallbackW copy error 0 L"C:\\users\\_user\\Temp\\IXP000.TMP\\oleaut32.dll" -> L"C:\\windows\\system32\\oleaut32.dll" fixme:setupapi:SetupDefaultQueueCallbackW notification 262144 params 32f63c,0 err:setupapi:SetupDefaultQueueCallbackW copy error 0 L"C:\\users\\_user\\Temp\\IXP000.TMP\\olepro32.dll" -> L"C:\\windows\\system32\\olepro32.dll" fixme:setupapi:SetupDefaultQueueCallbackW notification 262144 params 32f63c,0 err:setupapi:SetupDefaultQueueCallbackW copy error 0 L"C:\\users\\_user\\Temp\\IXP000.TMP\\stdole2.tlb" -> L"C:\\windows\\system32\\stdole2.tlb" The distribution is Ubuntu Studio 12.04.1 64bit Thanks in advance

  • BitBlt ignores CAPTUREBLT and seems to always capture a cached copy of the target...

    - by Jake Petroules
    I am trying to capture screenshots using the BitBlt function. However, every single time I capture a screenshot, the non-client area NEVER changes no matter what I do. It's as if it's getting some cached copy of it. The client area is captured correctly. If I close and then re-open the window, and take a screenshot, the non-client area will be captured as it is. Any subsequent captures after moving/resizing the window have no effect on the captured screenshot. Again, the client area will be correct. Furthermore, the CAPTUREBLT flag seems to do absolutely nothing at all. I notice no change with or without it. Here is my capture code: QPixmap WindowManagerUtils::grabWindow(WId windowId, GrabWindowFlags flags, int x, int y, int w, int h) { RECT r; switch (flags) { case WindowManagerUtils::GrabWindowRect: GetWindowRect(windowId, &r); break; case WindowManagerUtils::GrabClientRect: GetClientRect(windowId, &r); break; case WindowManagerUtils::GrabScreenWindow: GetWindowRect(windowId, &r); return QPixmap::grabWindow(QApplication::desktop()->winId(), r.left, r.top, r.right - r.left, r.bottom - r.top); case WindowManagerUtils::GrabScreenClient: GetClientRect(windowId, &r); return QPixmap::grabWindow(QApplication::desktop()->winId(), r.left, r.top, r.right - r.left, r.bottom - r.top); default: return QPixmap(); } if (w < 0) { w = r.right - r.left; } if (h < 0) { h = r.bottom - r.top; } #ifdef Q_WS_WINCE_WM if (qt_wince_is_pocket_pc()) { QWidget *widget = QWidget::find(winId); if (qobject_cast<QDesktopWidget*>(widget)) { RECT rect = {0,0,0,0}; AdjustWindowRectEx(&rect, WS_BORDER | WS_CAPTION, FALSE, 0); int magicNumber = qt_wince_is_high_dpi() ? 4 : 2; y += rect.top - magicNumber; } } #endif // Before we start creating objects, let's make CERTAIN of the following so we don't have a mess Q_ASSERT(flags == WindowManagerUtils::GrabWindowRect || flags == WindowManagerUtils::GrabClientRect); // Create and setup bitmap HDC display_dc = NULL; if (flags == WindowManagerUtils::GrabWindowRect) { display_dc = GetWindowDC(NULL); } else if (flags == WindowManagerUtils::GrabClientRect) { display_dc = GetDC(NULL); } HDC bitmap_dc = CreateCompatibleDC(display_dc); HBITMAP bitmap = CreateCompatibleBitmap(display_dc, w, h); HGDIOBJ null_bitmap = SelectObject(bitmap_dc, bitmap); // copy data HDC window_dc = NULL; if (flags == WindowManagerUtils::GrabWindowRect) { window_dc = GetWindowDC(windowId); } else if (flags == WindowManagerUtils::GrabClientRect) { window_dc = GetDC(windowId); } DWORD ropFlags = SRCCOPY; #ifndef Q_WS_WINCE ropFlags = ropFlags | CAPTUREBLT; #endif BitBlt(bitmap_dc, 0, 0, w, h, window_dc, x, y, ropFlags); // clean up all but bitmap ReleaseDC(windowId, window_dc); SelectObject(bitmap_dc, null_bitmap); DeleteDC(bitmap_dc); QPixmap pixmap = QPixmap::fromWinHBITMAP(bitmap); DeleteObject(bitmap); ReleaseDC(NULL, display_dc); return pixmap; } Most of this code comes from Qt's QWidget::grabWindow function, as I wanted to make some changes so it'd be more flexible. Qt's documentation states that: The grabWindow() function grabs pixels from the screen, not from the window, i.e. if there is another window partially or entirely over the one you grab, you get pixels from the overlying window, too. However, I experience the exact opposite... regardless of the CAPTUREBLT flag. I've tried everything I can think of... nothing works. Any ideas?

  • How to copy bytes from buffer into the managed struct?

    - by Chupo_cro
    I have a problem with getting the code to work in a managed environment (VS2008 C++/CLI Win Forms App). The problem is I cannot declare the unmanaged struct (is that even possible?) inside the managed code, so I've declared a managed struct but now I have a problem how to copy bytes from buffer into that struct. Here is the pure C++ code that obviously works as expected: typedef struct GPS_point { float point_unknown_1; float latitude; float longitude; float altitude; // x10000 float time; int point_unknown_2; int speed; // x100 int manually_logged_point; // flag (1 --> point logged manually) } track_point; int offset = 0; int filesize = 256; // simulates filesize int point_num = 10; // simulates number of records int main () { char *buffer_dyn = new char[filesize]; // allocate RAM // here, the file would have been read into the buffer buffer_dyn[0xa8] = 0x1e; // simulates the speed data (1e 00 00 00) buffer_dyn[0xa9] = 0x00; buffer_dyn[0xaa] = 0x00; buffer_dyn[0xab] = 0x00; offset = 0x90; // if the data with this offset is transfered trom buffer // to struct, int speed is alligned with the buffer at the // offset of 0xa8 track_point *points = new track_point[point_num]; points[0].speed = 0xff; // (debug) it should change into 0x1e memcpy(&points[0],buffer_dyn+offset,32); cout << "offset: " << offset << "\r\n"; //cout << "speed: " << points[0].speed << "\r\n"; printf ("speed : 0x%x\r\n",points[0].speed); printf("byte at offset 0xa8: 0x%x\r\n",(unsigned char)buffer_dyn[0xa8]); // should be 0x1e delete[] buffer_dyn; // release RAM delete[] points; /* What I need is to rewrite the lines 29 and 31 to work in the managed code (VS2008 Win Forms C++/CLI) What should I have after: array<track_point^>^ points = gcnew array<track_point^>(point_num); so I can copy 32 bytes from buffer_dyn to the managed struct declared as typedef ref struct GPS_point { float point_unknown_1; float latitude; float longitude; float altitude; // x10000 float time; int point_unknown_2; int speed; // x100 int manually_logged_point; // flag (1 --> point logged manually) } track_point; */ return 0; } Here is the paste to codepad.org so it can be seen the code is OK. What I need is to rewrite these two lines: track_point *points = new track_point[point_num]; memcpy(&points[0],buffer_dyn+offset,32); to something that will work in a managed application. I wrote: array<track_point^>^ points = gcnew array<track_point^>(point_num); and now trying to reproduce the described copying of the data from buffer over the struct, but haven't any idea how it should be done. Alternatively, if there is a way to use an unmanaged struct in the same way shown in my code, then I would like to avoid working with managed struct.

  • How do I copy the layout from a header of a JTabbedPane onto a JPanel?

    - by Snail
    I have created a "CollapsingPanel"class/sort of a JTabbedPane (code skeleton can be found at http://www.coderanch.com/t/341737/Swing-AWT-SWT-JFace/java/Expand-Collapse-Panels). It is in other words a lot of headers which you click on to show a hidden Panel. At the moment these header-panels are a rectangular box with a LineBorder around them. That is ugly! I'm wondering if there is a way to copy the layout that the JTabbedPane uses for its headers/titles (which is inhierted from Look&Feel I assume) and use it on my JPanel-based headers? So that my headers get a smooth look which is in line with the rest of the program (based on Look&Feel!) instead of looking like alien flat blocks. Illustrated below with the headers nicely circled in green ;) I want to apply the header-look from 2nd picture over the red header JPanel in picture 1: Picture 1: hxxp://img7.imageshack.us/img7/2319/34158982.png - change to http, I got <10 rep :( Pictrue 2: hxxp://img46.imageshack.us/img46/2572/jtabpane.png

  • Silverlight Project - Setting Reference to Copy Local false not working.

    - by cmaduro
    Why is it that when my Silverlight project is built, the output directory contains a bunch of culture specific directories: ar\System.Windows.Controls.resources.dll bg\System.Windows.Controls.resources.dll ca\System.Windows.Controls.resources.dll etc etc etc Also the root of the build output contains: System.Xml.Linq.dll System.windows.Controls.dll I have gone through the projects in my solution and made sure that "Copy Local" is set to false for all the referances of the mentioned dll files. Those 2 files were set to true, but I did switch them to false. Despite my effort to google an answer, I remain stuck.

  • How to copy a System.Drawing.Graphics over another Graphics?

    - by Simon T.
    We got some code that implement printing using Printdocument and it does all the drawing directly on the Graphics object received in the PrintEventArgs. It would be more convenient if the code doing the drawing used another canvas and we would add this canvas to the PrintEventArgs Graphics after. Since the code already depends on the Graphics object I need a canvas with this object. I also need a way to copy the canvas onto the PrintEventArgs Graphics. I can create a Graphicsfrom an Image but as far as I know it needs to be stored on the disk. Any suggestions?

  • How do I get Linq-to-SQL to refresh its local copy of a database record?

    - by Gary McGill
    Suppose I have an Orders table in my database and a corresponding model class generated by the VS2008 "Linq to SQL Classes" designer. Suppose I also have a stored procedure (ProcessOrder) in my database that I use to do some processing on an order record. If I do the following: var order = dataContext.Orders.Where(o => o.id == orderId).First(); // More code here dataContext.ProcessOrder(orderId); order.Status = "PROCESSED"; dataContext.SubmitChanges(); ...then I'll get a concurrency violation if the ProcessOrder stored proc has modified the order (which is of course very likely), because L2S will detect that the order record has changed, and will fail to submit the changes to that order. That's all fairly logical, but what if I want to update the order record after calling the stored proc? How do I tell L2S to forget about its cached copy and refresh it from the DB?

  • How do I copy only the values and not the references from a Python list?

    - by wrongusername
    Specifically, I want to create a backup of a list, then make some changes to that list, append all the changes to a third list, but then reset the first list with the backup before making further changes, etc, until I'm finished making changes and want to copy back all the content in the third list to the first one. Unfortunately, it seems that whenever I make changes to the first list in another function, the backup gets changed also. Using original = backup didn't work too well; nor did using def setEqual(restore, backup): restore = [] for number in backup: restore.append(number) solve my problem; even though I successfully restored the list from the backup, the backup nevertheless changed whenever I changed the original list. How would I go about solving this problem?

  • Python key word arguments

    - by pythonic metaphor
    I have several layers of function calls, passing around a common dictionary of key word arguments: def func1(**qwargs): func2(**qwargs) func3(**qwargs) I would like to supply some default arguments in some of the subsequent function calls, something like this: def func1(**qwargs): func2(arg = qwargs.get("arg", default), **qwargs) func3(**qwargs) The problem with this approach is that if arg is inside qwargs, a TypeError is raised with "got multiple values for keyword argument". I don't want to set qwargs["arg"] to default, because then func3 gets this argument without warrant. I could make a copy.copy of the qwargs and set "arg" in the copy, but qwargs could have large data structures in it and I don't want to copy them (maybe copy.copy wouldn't, only copy.deepcopy?). What's the pythonic thing to do here?

  • How to copy from C# control and paste link into excel.

    - by Steve H.
    I have an application that I want to link to excel. I have no preference which control is used as long as I can copy the data or control, and paste link into excel. When the data changes in my application, I want the cell to change in excel. I have a client that claims it is possible and he has seen it, but has no proof and may be confused. I have searched the internet and have come up with a number of half-solutions, and people who want the opposite of what I want. Does anyone know the full solution?

  • How do I create a downscaled copy of an FBO in OpenGL?

    - by Jasper Bekkers
    Hi, In order to speed up some post-processing shaders I'm using, I need to perform these operations on a framebuffer that is smaller in size than the actual window (about 1/4th or more). Most of the effects I want to optimize are simple blurring operations that could be replaced (for a large part) by smaller kernel and bilinear filtering. Thus, I need to create a copy of the current FBO into another one. However, I couldn't find anything, that works, on how to do this. I've tried using glBlitframebufferEXT and rendering a fullscreen quad into the other framebuffer, but both paths result in a black texture as output. How do I go about solving this problem?

  • How do I save a copy of the clipboard and then revert back to it?

    - by cksubs
    I'm reading words in a text box by simulating the key presses required to highligh and copy the text. When I'm done, I want the clipboard to be exactly how I found it. I was hoping I'd be able to do something like this: IDataObject clipboardBackup = Clipboard.GetDataObject(); Clipboard.Clear(); //Save other things into the clipboard here, etc// Clipboard.SetDataObject(clipboardBackup); But that doesn't seem to work. It looks like you can go the route of specifically trying for text, audio, pictures, etc. and then saving them accordingly. (I guess 'data object' is specialized like that in my example too, I was hoping it was generic.) I'd prefer not to use cases for every possible type of clipboard data, both to be more concise and to make sure I never lose the data regardless of format. Any tips for grabbing any and all of the clipboard and then restoring it?

  • How do I copy security information when creating a new folder?

    - by dhh
    In my app I'm creating folders for archiving old stuff from a harddisc. When creating a new folder I must copy all NTFS rights (Groups / Users) from the source folder to the newly created destination folder. Here is what I've written so far: FileSecurity fileSecurity = File.GetAccessControl(filenameSource, AccessControlSections.All); FileAttributes fileAttributes = File.GetAttributes(filenameSource); File.SetAccessControl(filenameDest, fileSecurity); File.SetAttributes(filenameDest, fileAttributes); Is this really all I ought to do or am I missing something important?

  • Dreamweaver regular expression substitution followed by number

    - by mark
    Hi. I'm using Dreamweaver to update copyright dates across my site. I want to preserve the existing spacing (or lack thereof) between years. Examples: © 2002-2008 should update to © 2002-2009 © 2003 - 2008 should update to © 2003 - 2009 This is the regular expression I'm using to accomplish this in Dreamweaver's find & replace function Find: ©\s*(\d{4}\s*-\s*)\d{3}[^9] Replace: © $1 2009 Here's the PROBLEM: This expression works, but has that that extra space between the hyphen and 2009. If I write the replace expression without the space, as © $12009 then dreamweaver looks for the 12,009th substitution in the find expression, and, not finding one, prints $12009. Any ideas?

  • How can I use BeanUtils copyProperties to copy from boolean to Boolean?

    - by carrier
    BeanUtils copyProperties, out of the box, doesn't seem to handle copying from Boolean object properties to boolean primitive properties. I figured I could create and register a converter to handle this, but that just didn't seem to work. So, how can I use BeanUtils to copy the properties from class Source to class Destination where: public class Destination { private boolean property; public boolean isProperty() { return property; } public void setProperty(boolean property) { this.property = property; } } public class Source{ private Boolean property; public Boolean getProperty() { return property; } public void setProperty(Boolean property) { this.property = property; } }

  • How can I copy an XmlNode from one XmlDocument to another?

    - by Chris Wenham
    I'm building a tool that authors/edits XML files, and I want to be able to populate it with template fragments defined in another XML file. For example, the tool has an "Add FooBarBaz Element" button that adds a element to the new document being created, and I want to add FooBarBaz by copying it from a template. Or let's say this is my template file: <Templates> <FooBarBaz Attribute="Value"> <ChildElement/> </FooBarBaz> </Templates> I can then grab a template fragment with .GetElementsByTagName("FooBarBaz"), and I'd like to be able to inject it into the new document with something like .AppendChild(templateNode). But the problem is that an XmlNode cannot be copied from one XmlDocument to another, even if you use .Clone() or .CloneNode(), because AppendChild() throws an exception saying that the template element belongs to another context. Is there an easy way to copy a System.Xml.XmlNode between System.Xml.XmlDocuments?

  • The best way to ensure only 1 copy of bash script is running?

    - by depesz
    What is the simplest/best way to ensure only 1 copy of given script is running - assuming it's bash on linux? At the moment I'm doing: ps -C script.name.sh > /dev/null 2>&1 || ./script.name.sh but it has several issues: it puts the check outside of script it doesn't let me run the same script from separate accounts - which I would like sometimes. -C checks only first 14 characters of process name Of course I can write my own pidfile handling, but I sense that there should be some simple way to do it.

  • C# - Copy dlls to the exe output directory when using dependency injection with no references?

    - by NotDan
    I have a C# solution that I am using dependency injection to resolve references between dlls. I have an exe project and some other dll projects that are not referenced by the exe (It uses the dlls through the IoC container). The project settings are the default, visual studio settings where it builds each dll in it's own folder. Since the exe doesn't reference the dlls, they never get copied to the output directory of the exe and don't get found by the IoC framework. How do you handle this? Do you build them all in the same directory? Use post build copy commands? Or something else?

  • Python: How To copy function parameters into object's fields effortlessly ?

    - by bandana
    Many times I have member functions that copy parameters into object's fields. For Example: class NouveauRiches(object): def __init__(self, car, mansion, jet, bling): self.car = car self.mansion = mansion self.jet = jet self.bling = bling Is there a python language construct that would make the above code less tedious? One could use *args: def __init__(self, *args): self.car, self.mansion, self.jet, self.bling = args +: less tedious -: function signature not revealing enough. need to dive into function code to know how to use function -: does not raise a TypeError on call with wrong # of parameters (but does raise a ValueError) Any other ideas? (Whatever your suggestion, make sure the code calling the function does stays simple)

  • How to copy QT folder to another folder without reinstalling it?

    - by Oleg
    I have QT installed on disc D (on Windows). And I want to move it to disc C. Is it possible to do that? If I just copy QT folder from C to D then I see lot of errors when I compile my applications that use QT. Errors are because qmake.exe contains full paths to include, bin and libs folders inside. So, when I create solution for Visual Studio 2005 using qmake - then this solution contains dependencies to old QT folder from disc D. And I found no way how to remove this dependencies without reinstalling of QT. It is not a big problem for one my single machine - I can reinstall. But I need to deliver this change then to tens and hundreds of other developers machines and I want to make it as easy as possible without need to reinstall QT.

  • How to keep a Generic list unmodified when its copy is modified?
