I'm trying to write some Python code to talk to the Thorlabs APT ActiveX control. I'm basing my code on the code found on this page , but trying to use PyQt4 ActiveX container instead of the wxPython ActiveX container. It works for a very simple ActiveX methods, however, I get an error when trying to call a method that takes arguments. This code works and shows the about box for Thorlabs APT: import sys from ctypes import * from PyQt4 import QtGui from PyQt4 import QAxContainer class APTSystem(QAxContainer.QAxWidget): def __init__(self, parent): self.parent = parent super(APTSystem, self)._

I have created a COM component for my work. I have registered the component also. On my system I have two VM workstations. In my first workstation it works fine. In my second workstation it displays an error box containing the message this program needs a rumtime and closes an unusual way please contact applications administrator . I thought that this was because of not registering the dll in the second worksation then I registered and it works fine. When i tried to test the same in win2k8 machine even though I register the COM component successfully it shows the above said erroe window?? Can

I open Matlab engine in an initialization thread, doing : bool MY_MATLAB_ENGINE_o::Open() { // Handle the case where engine is already open if( MatlabEngine ) { return true; } else if( !( MatlabEngine = engOpen( 0 ) ) ) { return false; } IsEngineOpen.SetValue( true ); return true; } Function engOpen() opens a COM channel to Matlab. Once the engine is open, the thread falls in wait event mode. Then, in another thread, I do this : bool MY_MATLAB_ENGINE_o::ChangeDirectory( QString strPath ) { QString strPathToScript = "cd('" + strPath + "');"; QByteArray ba = strPathToScript.toLatin1(); const

I have a wierd application loading mechanism. I have a boostrapping exe file with all the other DLLs and the application itself inside it's resources. These files (assemblies) are extracted from resources and loaded ond emand because i'm attaching to the Assemblyresolve event of the current AppDomain. [STAThread] static void Main() { // if the command line contains extract then extract the dlls, next run will resolve assemblies from disk bool saveDllsToDisk = new List<string>(Environment.GetCommandLineArgs()).Contains("extract"); // if the command line contains bin then use the bin folder

How to return List from c# method and Use the List return values in c++ can u give guidance how to do it?? I going like following way my complete scenario: in c# DemoLib.cs usng System;using System.Collections.Generic; public interface IDiscover { void GetList1(); String GetList2(); List<string> GetList3(); }; namespace DemoLibrary { class DemoLib { public void GetList1() { Console.WriteLine(" I am from Void GetList()"); } public string GetList2() { Console.WriteLine(" I am from string GetList()"); return "Stack OverFlow"; } public List<string> GetList3() { List<string> li=new List<string>();

In WPF I'm getting IntPtr handle using this code: IntPtr mainWindowHandle = new WindowInteropHelper(Application.Current.MainWindow).Handle When I finish using this handle, do I need to release it in anyway (e.g. using Marshal.FreeHGlobal() method) ? EDIT: I was thinking about Marshal.FreeHGlobal(), not Marshal.Release(), sorry! This is not in any way related to COM, Marshal.Release() does not apply. You simply get a copy of the native window handle, it does not have to be released. You need to stop using the handle when the window is destroyed. Signaled by the Window.Close event. 来源： https:/

Is it possible to get the number of pages in word document or number of slides in a ppt. I have done a lot of research on it and i am desperately looking for solution. I saw that it is very difficult to get it done in PHP on linux server. I would be ok with Java also, but is it possible. I checked the apache POI library, but would it work for both PPT, PPTX, doc and docx. I am rigorously searching for some solution but i am unable to get one. Any help would be really really appreciated. To get meta data properties of doc,docx,ppt and pptx like number of pages, number of slides **USING PHP** i
