• How should I launch a Portable Python Tkinter application on Windows without ugliness?

  - by Andrew

  I've written a simple GUI program in python using Tkinter. Let's call this program 'gui.py'. My users run 'gui.py' on Windows machines from a USB key using Portable Python; installing anything on the host machine is undesirable. I'd like my users to run 'gui.py' by double-clicking an icon at the root of the USB key. My users don't care what python is, and they don't want to use a command prompt if they don't have to. I don't want them to have to care what drive letter the USB key is assigned. I'd like this to work on XP, Vista, and 7. My first ugly solution was to create a shortcut in the root directory of the USB key, and set the "Target" property of the shortcut to something like "(root)\App\pythonw.exe (root)\App\gui.py", but I couldn't figure out how to do a relative path in a windows shortcut, and using an absolute path like "E:" seems fragile. My next solution was to create a .bat script in the root directory of the USB key, something like this: @echo off set basepath=%~dp0 "%basepath%App\pythonw.exe" "%basepath%\App\gui.py" This doesn't seem to care what drive letter the USB key is assigned, but it does leave a DOS window open while my program runs. Functional, but ugly. Next I tried a .bat script like this: @echo off set basepath=%~dp0 start "" "%basepath%App\pythonw.exe" "%basepath%\App\gui.py" (See here for an explanation of the funny quoting) Now, the DOS window briefly flashes on screen before my GUI opens. Less ugly! Still ugly. How do real men deal with this problem? What's the least ugly way to start a python Tkinter GUI on a Windows machine from a USB stick?

• WPF/MVVM - keep ViewModels in application component or separate?

  - by Anders Juul

  Hi all, I have a WPF application where I'm using the MVVM pattern. I get the VM activated for actions that require user input and thus need to activate views from the VM. I've started out separating the VMs into a separate component/assembly, partly because I see them as the unit testable part, partly because views should rely on VM, not the other way round. But when I then need to bring up a window, the window is not known by the VM. All introductions I find place the VM in the WPF/App component, thus eliminating the problem. This article recommends keeping them in separate layers : http://waf.codeplex.com/wikipage?title=Architecture%20-%20Get%20The%20Big%20Picture&referringTitle=Home As I see it, I have the following choices Move VMs to the WPF/App assembly to allow VMs to access the windows directly. Place interfaces of views in VM-assembly, implement views in WPF/App assembly and register the connection through IOC or alternative ways. File a 'request' from the VM into some mechanism/bus that routes the request (but which mechanism!? E.g something in Prism?!) What's the recommendation? Thanks for any comments, Anders, Denmark

• Why SetMinimumSize sets the minimal heights but not width?

  - by Roman

  Here is my code: import javax.swing.*; import java.awt.*; public class PanelModel { public static void main(String[] args) { JFrame frame = new JFrame("Colored Trails"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); JPanel firstPanel = new JPanel(); firstPanel.setLayout(new GridLayout(4, 4)); firstPanel.setMaximumSize(new Dimension(4*100, 4*100)); firstPanel.setMinimumSize(new Dimension(4*100, 4*100)); JButton btn; for (int i=1; i<=4; i++) { for (int j=1; j<=4; j++) { btn = new JButton(); btn.setPreferredSize(new Dimension(100, 100)); firstPanel.add(btn); } } mainPanel.add(firstPanel); frame.add(mainPanel); frame.setSize(520,600); //frame.setMinimumSize(new Dimension(520,600)); frame.setVisible(true); } } When I increase the size of the window (by mouse) I see that my panel does not increase its size. It is the expected behavior (because I set the maximal size of the panel). However, when I decrease the size of the window, I see that width of the panel is decreased too (while the height is constant). So, the setMinimumSize works only partially. Why is that?

• loading google maps drawing manager object

  - by psychok7

  So i am using Google Maps Drawing Manager to draw some polygons and i am saving the lat e long coordinates to my database. Now my question is, after i load that to my array, how can i rebuild the saved polygon back into my map? I can't seem to find a code to understand that. this is what i have now : window.initialize_2 = function () { var mapOptions = { center: new google.maps.LatLng(-34.397, 150.644), zoom: 8, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = maplimits; var drawingManager = new google.maps.drawing.DrawingManager({ drawingMode: google.maps.drawing.OverlayType.MARKER, drawingControl: true, drawingControlOptions: { position: google.maps.ControlPosition.TOP_CENTER, drawingModes: [ google.maps.drawing.OverlayType.POLYGON] }, markerOptions: { icon: 'images/beachflag.png' }, polygonOptions: { fillColor: '#ffff00', fillOpacity: 10, strokeWeight: 5, clickable: true, editable: true, zIndex: 1 } }); var coord_listener = google.maps.event.addListener(drawingManager, 'polygoncomplete', function (polygon) { var coordinates = (polygon.getPath().getArray()); console.log(coordinates); window.poly = polygon; }); //delete shape google.maps.event.addListener(drawingManager, 'overlaycomplete', function (e) { if (e.type != google.maps.drawing.OverlayType.MARKER) { // Switch back to non-drawing mode after drawing a shape. drawingManager.setDrawingMode(null); // Add an event listener that selects the newly-drawn shape when the user // mouses down on it. var newShape = e.overlay; newShape.type = e.type; google.maps.event.addListener(newShape, 'click', function () { setSelection(newShape); }); setSelection(newShape); } }); // Clear the current selection when the drawing mode is changed, or when the // map is clicked. google.maps.event.addListener(drawingManager, 'drawingmode_changed', clearSelection); google.maps.event.addListener(map, 'click', clearSelection); drawingManager.setMap(map); }

• What causes my borderless C++ app to crash when overriding WndProc?

  - by Ste

  I use a form with border NONE. I need to override WndProc for resize and move form. However, using this code, my app crashes! static const int WM_NCHITTEST = 0x0084; static const int HTCLIENT = 1; static const int HTCAPTION = 2; protected: virtual void Form1::WndProc(System::Windows::Forms::Message %m) override { switch (m.Msg) { case WM_NCHITTEST: if (m.Result == IntPtr(HTCLIENT)) { m.Result = IntPtr(HTCAPTION); } break; } Form1::WndProc(m); } virtual System::Windows::Forms::CreateParams^ get() override { System::Windows::Forms::CreateParams^ cp = __super::CreateParams; cp->Style |= 0x40000; return cp; } How can I fix my code not to crash but still allow my form to be moved and resized?

• How can I bind another DependencyProperty to the IsChecked Property of a CheckBox?

  - by speedmetal

  Here's an example of what I'm trying to accomplish: <Window x:Class="CheckBoxBinding.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <StackPanel> <CheckBox Name="myCheckBox">this</CheckBox> <Grid> <Grid.Resources> <Style TargetType="ListBox"> <Style.Triggers> <Trigger Property="{Binding ElementName=myCheckBox, Path=IsChecked}" Value="True"> <Setter Property="Background" Value="Red" /> </Trigger> </Style.Triggers> </Style> </Grid.Resources> <ListBox> <ListBoxItem>item</ListBoxItem> <ListBoxItem>another</ListBoxItem> </ListBox> </Grid> </StackPanel> </Window> When I try to run it, I get this XamlParseException: A 'Binding' cannot be set on the 'Property' property of type 'Trigger'. A 'Binding' can only be set on a DependencyProperty of a DependencyObject. So how can I bind a property on the ListBox to the IsChecked property of a CheckBox?

• Boost::Container::Vector with Enum Template Argument - Not Legal Base Class

  - by CuppM

  Hi, I'm using Visual Studio 2008 with the Boost v1.42.0 library. If I use an enum as the template argument, I get a compile error when adding a value using push_back(). The compiler error is: 'T': is not a legal base class and the location of the error is move.hpp line 79. #include <boost/interprocess/containers/vector.hpp> class Test { public: enum Types { Unknown = 0, First = 1, Second = 2, Third = 3 }; typedef boost::container::vector<Types> TypesVector; }; int main() { Test::TypesVector o; o.push_back(Test::First); return 0; } If I use a std::vector instead it works. And if I resize the Boost version first and then set the values using the [] operator it also works. Is there some way to make this work using push_back()?

• Resizing Tab Bar Controller Views (iPhone dev)

  - by damiandawber

  Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

• Getting base address of a process

  - by yoni0505

  I'm trying to make a program that read the timer value from Minesweeper. (OS is windows 7 64bit) Using cheat engine I found the base address of the variable, but it changes every time I run Minesweeper. What do I need to do to find out the base address automatically? Does it have something to do with the executable base address? Here's my code: #include <windows.h> #include <iostream> using namespace std; int main() { DWORD baseAddress = 0xFF1DAA38;//always changing DWORD offset1 = 0x18; DWORD offset2 = 0x20; DWORD pAddress1; DWORD pAddress2; float value = 0; DWORD pid; HWND hwnd; hwnd = FindWindow(NULL,"Minesweeper"); if(!hwnd)//didn't find the window { cout <<"Window not found!\n"; cin.get(); } else { GetWindowThreadProcessId(hwnd,&pid); HANDLE phandle = OpenProcess(PROCESS_VM_READ,0,pid);//get permission to read if(!phandle)//failed to get permission { cout <<"Could not get handle!\n"; cin.get(); } else { ReadProcessMemory(phandle,(void*)(baseAddress),&pAddress1,sizeof(pAddress1),0); ReadProcessMemory(phandle,(void*)(pAddress1 + offset1),&pAddress2,sizeof(pAddress2),0); while(1) { ReadProcessMemory(phandle,(void*)(pAddress2 + offset2),&value,sizeof(value),0); cout << value << "\n"; Sleep(1000); } } } }

• Enumerating pixel formats for adaptors and modes with OpenGL

  - by Robinson

  I'm trying to code an OpenGL path for my 3D engine. The D3D path enumerates all device adaptors, all modes (by mode I mean bit depth, dimensions, available windowed, and refresh rate) for each adaptor and then all pixel formats available for the given mode and adaptor, along side certain useful caps (shader version, filter types, etc.). So, I have broadly got the following protected functions in the class: // Enumerate all back/front buffer combinations. virtual void EnumerateBackFrontBufferCombinations(CComPtr<IDirect3D9>& d3d9); // Enumerate all depth/stencil formats. virtual void EnumerateDepthStencilFormats(CComPtr<IDirect3D9>& d3d9); // Enumerate all multi-sample formats. virtual void EnumerateMultiSampleTypes(CComPtr<IDirect3D9>& d3d9); // Enumerate all device formats, i.e. dynamic, static, render target, etc. virtual void EnumerateMapFormats(CComPtr<IDirect3D9>& d3d9); // Enumerate all capabilities. virtual void EnumerateCapabilities(CComPtr<IDirect3D9>& d3d9); The adaptors are enumerated with EnumDisplayDevices, the modes (resolutions and refresh rates) are enumerated with EnumDisplaySettings, so this can be done for either GL or D3D. The other functions I'm not so sure about with OpenGL. What are the equivalents to the IDirect3D9's CheckDeviceType, CheckDeviceFormat, CheckDeviceMultiSampleType, CheckDepthStencilMatch? I know I can use DescribePixelFormat, given a DC, but you kind-of need to have created the window before you can use a DC with it, but you can't create the window correctly until you know what formats you're going to use. Any tips you can give me? Thanks.

• Is it possible to render PDF (fPDF) via a javascript?

  - by J. LaRosee

  So, I'm passing some values via jQuery to the server, which generates PDF garble. It goes something like this: $.post('/admin/printBatch', data, // Some vars and such function(data){ if(data) { var batch = window.open('','Batch Print','width=600,height=600,location=_newtab'); var html = data; // Perhaps some header info here?! batch.document.open(); batch.document.write(html); batch.document.close(); $( this ).dialog( "close" ); // jQuery UI } else { alert("Something went wrong, dawg."); } return false; }); The output file looks roughly like so: $pdf->AddPage(null, null, 'A PDF Page'); //.... $pdf->Output('', 'I'); // 'I' sends the file inline to the browser (http://fpdf.org/en/doc/output.htm) What gets rendered to the browser window: %PDF-1.3 3 0 obj <> endobj 4 0 obj <> stream ... I'm missing something major, I just know it... thoughts? Thanks, guys.

• Dockable panes created in CChildFrame not visible the second time the app. starts.

  - by Nijenhuis

  Hi, I have created some dockable panes in CChildFrame::OnCreate() The first time i start the application they are shown. The second time i start the application they are created but the splitterwindows are completly against the sides of the clients area (bottom and right), so not visible. So i have to use the mouse to pull the splitters into the clientarea so that the dockable windows become visible again. If i do File-New in my app a new client window is created and showing the dockable windows as they should be. I Think this has something to do with saving the windows layout in the registry, because if i change SetRegistryKey(_T("61sakjgsajkdg")); in the CWinApp derived class of my app. and rerun they are shown again the first time. (but not the second time i restart the app). How can i save the layout of those dockable windows as well, so if i restart my app. they are visible ? Or else how do i prevent my app. of overwritting the window layout with the one previously saved. Something to do with LoadCustomState() and SaveCustomState() ?, i could no find any info on howto implement those methods. I have here a link to the demo project to demonstrate what i mean: http://www.4shared.com/file/237193472/c384f0f6/GUI60.html Could someone tell me how to show those dockable windows in my CChildFrame class the second time the app starts?

• c# - clear surface when resizing

  - by dhh

  Hello, I'm trying to build my own custom control for a windows forms application in C#.Net. Currently I paint some rectangles and other graphic elements using the paint event. When I now resize the app form to fit the desktop size, all elements are repainted (which is exactly the behaviour I need) but the old one's are shown in the background. Here's what I'm doing by now: Pen penDefaultBorder = new Pen(Color.Wheat, 1); int margin = 5; private void CustomControl_Paint(object sender, PaintEventArgs e) { CustomControl calendar = (CustomControl)sender; Graphics graphics = e.Graphics; graphics.Clear(Color.WhiteSmoke); graphics.DrawRectangle(penDefaultBorder, margin, margin, calendar.Width - margin * 2, calendar.Height - margin * 2); //... } Neither the graphics.Clear, nor adding a graphics.FillRectangle(...) will hide the old rectangle from the surface. Ideas? Thank you all.

• What's a better way to display a handle for resizing a view on iPhone / iPad?

  - by Christian

  I want to display a handle at the corners of a UIView that can be used to resize the view. How can I display the handles floating on the top of everything else and still have a connection to and be in sync with a view? The solution I implemented before looks like this: I put the view into another view that shows the handles on top of the corners. The problem with this approach is that the handles add extra space to the original view's size. Since Apple recommends at least 40 x 40 px for the size of a button, it is not very little space and also goes beyond the visible bounds of the original view. Another problem is that the original view has to be encapsulated in this 'helper view' object and thus becomes a part of something although it really is the main component.

• Is there a way to touch-enable scrolling in a WPF ScrollViewer?

  - by Brian Sullivan

  I'm trying to create a form in a WPF application that will allow the user to use iPhone-like gestures to scroll through the available fields. So, I've put all my form controls inside a StackPanel inside a ScrollViewer, and the scrollbar shows up as expected when there are too many elements to be shown on the screen. However, when I try to test this on my touch-enabled device, a panning gesture (placing a finger down on the surface and dragging it upward) does not move the viewable area down as I would expect. When I simply put a number of elements inside a ListView, the touch gestures work just fine. Is there any way to enable the same kind of behavior in a ScrollViewer? My window is structured like this: <Window x:Class="TestTouchScrolling.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <Grid> <ScrollViewer Name="viewer" VerticalScrollBarVisibility="Auto"> <StackPanel Name="panel"> <StackPanel Orientation="Horizontal"> <Label>Label 1:</Label> <TextBox Name="TextBox1"></TextBox> </StackPanel> <StackPanel Orientation="Horizontal"> <Label>Label 2:</Label> <TextBox Name="TextBox2"></TextBox> </StackPanel> <StackPanel Orientation="Horizontal"> <Label>Label 3:</Label> <TextBox Name="TextBox3"></TextBox> </StackPanel> <!-- Lots more like these --> </StackPanel> </ScrollViewer> </Grid>

• Possible to InvalidateVisual() on a given region instead of entire WPF control?

  - by Scott Bilas

  I have a complex WPF control that draws a lot of primitives in its OnRender (it's sort of like a map). When a small portion of it changes, I'd only like to re-issue render commands for the affected elements, instead of running the entire OnRender over. While I'm fine with my OnRender function's performance on a resize or whatever, it's not fast enough for mouse hover-based highlighting of primitives. Currently the only way I know how to force a screen update is to call InvalidateVisual(). No way to send in a dirty rect region to invalidate. Is the lowest granularity of WPF screen composition the UI element? Will I need to do my renders of primitives into an intermediate target and then have that use InvalidateVisual() to update to the screen?

• c++ use of winmain()

  - by Jack

  Hi, I just started learning programming for windows in c++. I had this crazy image, that win32 programming is based on calling windows functions and sending parameters to and from them. Like, when you want to create window, you call some win32 function that handles windows GUI and say "Hi, please, create me new window, 100 x 100 px, with two buttons", and that GUI function says "Hi, no problem, when something happends, like user clicks one button, I will change this variable xy located in this location". So, I thought that it will be very similiar to console programming. But the very first instruction surprised me. I always thought that every program executes main() function first. So, when I launch app, windows stores some parameters on top of stack and run that application. So I assumed that initializing main() is just a c++ way to tell the compiler where the first instruction should be. But in win32 programming, there is function called winmain() which starts first. So I am little confused. I thought it´s rule that compiler must have main() to start with, that main just defines where ti start, like some start point identifier. So, please, why is there winmain() function instead of main()? When I thought that C++ programming is as logical as assembler, it confuses me once again.

• Can this auto-stretcing scenario be realized undex XHTML/CSS?

  - by Vilx-

  I want two horizontal areas in my webpage. The first one is the menu. It's on the top. Unfortunately I don't know its size, and it might change in response to user actions. Below the menu is the main area which should stretch at least as far as the bottom of the window (if there is little content) or beyond (if there is a lot of content. To illustrate with ASCII art: +----------------------------------------------------+ | This area resizes vertically depending on contents | +----------------------------------------------------+ | This area stretches to the bottom of the window, | | but can be even larger if necessary. Note: this | | should be a separate area because it will contain | | children with height:100% as well. | | | +----------------------------------------------------+ Can this be done? Can it be done with Javascript? Added: To put things in perspective and avoid confusion, think of it this way: the top menu is generated by myself, but the bottom area is an IFrame which I want to fill the rest of the page. This is what it eventually comes down to anyway in my case.

• Safari/Chrome (Webkit) - Cannot hide iframe vertical scrollbar

  - by BrainCore

  Hello, I have an iframe on www.mydomain.com that points to support.mydomain.com (which is a CNAME to a foreign domain). I automatically resize the height of my iframe so that the frame will not need any scrollbars to display the contained webpage. On Firefox and IE this works great, there is no scrollbar since I use <iframe ... scrolling="no"></iframe>. However, on webkit browsers (Safari and Chrome), the vertical scrollbar persists even when there is sufficient room for the page without the scrollbar (the scrollbar is grayed out). How do I hide the scrollbar for webkit browsers? Thanks, Ken

• Programmatically Download Image to Desktop from Remote App with Ruby?

  - by viatropos

  I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and app resizes image image downloads automatically to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby.

• Including partial views when applying the Mode-View-ViewModel design pattern

  - by Filip Ekberg

  Consider that I have an application that just handles Messages and Users I want my Window to have a common Menu and an area where the current View is displayed. I can only work with either Messages or Users so I cannot work simultaniously with both Views. Therefore I have the following Controls MessageView.xaml UserView.xaml Just to make it a bit easier, both the Message Model and the User Model looks like this: Name Description Now, I have the following three ViewModels: MainWindowViewModel UsersViewModel MessagesViewModel The UsersViewModel and the MessagesViewModel both just fetch an ObserverableCollection<T> of its regarding Model which is bound in the corresponding View like this: <DataGrid ItemSource="{Binding ModelCollection}" /> The MainWindowViewModel hooks up two different Commands that have implemented ICommand that looks something like the following: public class ShowMessagesCommand : ICommand { private ViewModelBase ViewModel { get; set; } public ShowMessagesCommand (ViewModelBase viewModel) { ViewModel = viewModel; } public void Execute(object parameter) { var viewModel = new ProductsViewModel(); ViewModel.PartialViewModel = new MessageView { DataContext = viewModel }; } public bool CanExecute(object parameter) { return true; } public event EventHandler CanExecuteChanged; } And there is another one a like it that will show Users. Now this introduced ViewModelBase which only holds the following: public UIElement PartialViewModel { get { return (UIElement)GetValue(PartialViewModelProperty); } set { SetValue(PartialViewModelProperty, value); } } public static readonly DependencyProperty PartialViewModelProperty = DependencyProperty.Register("PartialViewModel", typeof(UIElement), typeof(ViewModelBase), new UIPropertyMetadata(null)); This dependency property is used in the MainWindow.xaml to display the User Control dynamicly like this: <UserControl Content="{Binding PartialViewModel}" /> There are also two buttons on this Window that fires the Commands: ShowMessagesCommand ShowUsersCommand And when these are fired, the UserControl changes because PartialViewModel is a dependency property. I want to know if this is bad practice? Should I not inject the User Control like this? Is there another "better" alternative that corresponds better with the design pattern? Or is this a nice way of including partial views?
