handle

问题 As mentioned in a related answer, it is possible to get the handles of all open figures using: hFigs = findall(groot, 'Type', 'figure'); but this results in a list that contains both "old" figure and "new" uifigure handles. How can I separate hFigs into two lists, one containing only figure and the other only uifigure references? 回答1: To distinguish between figure and uifigure objects programatically, we can use a slight adaptation of what I suggested here: function tf = isUIFigure(hFigList)

问题 I have script handling figures so that I can print and input them in a latex document with scale = 1 and everything looks nice. In this context I want to save the figure, axes and legend handles. Is there a way to save them like when using fig = figure . I know two 'hacks' 1) nfig = nfig+1; fig = figure(nfig); plot() ax = gca leg = legend() 2) nfig = nfig+1; fig = figure(nfig); ax = subplot(1,1,1) plot() leg = legend() My script function fig_set(fig,ax,leg,width,heigth,font_size) %% fig_set

问题 I have a C# windows application and ultimately launches a dialog from an interop component. The problem is that this dialog window sometimes appears behind the c# application's main window, forcing a user to alt-tab to find it. I've put measures into place to find this dialog window and bring it forward... private static extern bool SetForegroundWindow(IntPtr hWnd); public class SearchData { public string Wndclass; public string Title; public IntPtr hWnd; } private static extern bool

问题 Is there anyway to get the control handle or other information with i can indentify a control having only TMessage variable? Question is Delphi related. the thing im doing is that im hooking several controls wndproc with one function and i need to find what control message is that. code: unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, VirtualTrees, XML.VerySimple, Vcl.StdCtrls,

问题 What would be the best way to make an element draggable when clicking anywhere in the window? Would I have to use a container <div> that covers the whole window? I tried making the body draggable but that didn't work. The problem with using a container <div> is that it moves and therefore doesn't cover the whole of the screen any more after it has been dragged. What about making a really vast container <div> that spans a large number of pixels in every direction so you would never get to the

问题 I've got a routine where I process-walk to obtain the HANDLE of each process as I 'walk' down the list (which works fine), but my issue lies when I do: HANDLE h = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID) where PROCESS_ALL_ACCESS is the access token, handle inheritance is set to FALSE , and pe32 is a PROCESSENTRY32 GetLastError() returns error code 5, and all the handles that are made are addresses which do not correspond to any appropriate process in Spy++32/64 (I've tried

问题 (This question is a toughie... it might require knowledge of NTFS and/or the use of NT Native APIs; be warned.) :) If I'm given two HANDLE s to two files, how can I definitively (not just with high probability) find out if the two HANDLE s belong to the exact same file and stream on the disk? This means, for example, checking the 8-byte NTFS file IDs isn't enough, because two HANDLE s with the same file ID can be pointing to different data streams of the same file, and I need to find out if

问题 Info: .Net 4.5 Tested on: Win7 64 bit Win10 64 bit (Virtual Box) I am trying to get a list of handles of an external process and return their names as string so I can close a specific one afterwards. Therefore i wrote this function using the Win32API which will check if the handle is the handle i want to close: ` const int CNST_SYSTEM_HANDLE_INFORMATION = 16; const uint STATUS_INFO_LENGTH_MISMATCH = 0xc0000004; public static string getObjectTypeName(Win32API.SYSTEM_HANDLE_INFORMATION shHandle

问题 In Matlab, I have a function handle defined as a vector like this F = @(x) [... coeff1*x(1)*x(4); ... coeff2*x(3); ... coeff3*x(7)*x(3) ... ]; In reality it has 150 rows. I need to extract different subsets the functions in the rows. For example make a new handle from the rows 3:17 of those in F . But I can't just go indexing a handle. Is there a solution? Edit: I need the subset as a new handle, in other words I can not evaluate the entire F and just select the solution rows. Thanks in

问题 Background: I've got a large existing process (it happens to be on AIX, so basically POSIX semantics) that's part of an even larger system. The existing processes are designed to run continuously. A new requirement for this process is to handle a new kind of complex input stream. In order to reduce risk, I've decided to fork/exec a child process to do the actual input processing, which isolates the existing main process from problems such as crashes or hangs on malformed input data. The child
