问题 After checking Microsoft's documentation on system tray icons (that I could find): Shell_NotifyIconA function NOTIFYICONDATAA structure I've noticed that a window handle (HWND) is REQUIRED. This is very bad for what I'm trying to accomplish, as I'm looking to create a program that only reacts to the system tray: it doesn't "minimize" the window to the tray, it just uses notifications (clicking/right clicking on the icon) to interact. How would I go about doing this? 回答1: The Windows 7 SDK

问题 I'm creating a win32 application and initialized my statusbar width variables in my WM_CREATE switch case. case WM_CREATE: { int statwidths[] = { 200, -1 }; } break; I would like to access statwidths[ 0 ] in my WM_SIZE switch case as that number will be used to determine the size of the rest of my windows in my program. case WM_SIZE: { int OpenDocumentWidth = statwidths[ 0 ]; } break; Is there a way to do this? They are both in the same switch statement in the same file. 回答1: If these are

问题 In my app, I hook some Windows API calls by patching PE Import Access table. I enumerate all modules in a process using this Tool Help API (Module32First,Module32Next). One of the functions I hook is LoadLibrary. In it, I load module by calling the original LoadLibrary and then I enumerate again all the loaded modules to detect new loaded modules I have not hooked yet (because LoadLibrary can load the specified module plus all the modules it depends on). It works fine most of the time. But

问题 I was working on a project which uses direct composition based on this Article: Windows with C++ : High-Performance Window Layering Using the Windows Composition Engine I was able to recreate the example and it is working.

问题 This question already has answers here : What is the maximum URL length you can pass to the Wininet function, HttpOpenRequest? (3 answers) Closed 2 years ago . I'm aware there is a similar question here. However my symptoms differ. There seems to be some kind of URL length restriction in place that I couldn't find documented. The limit seens to be 2084 (sic! not 2048!) characters in the URL. The easiest repro is just a console application with this code: #include "stdafx.h" #include "urlmon.h

问题 The goal is to get the full path to the document opened in an instance of Microsoft Word that I have a process reference for. Pseudocode Example: Process myWordProcess = something; // This is my process reference DocumentInformation docInfo = SomeNamespace.GetDocumentInformation(myWordProcess); string documentPath = docInfo.FullName; // "C:\User\Foo\Documents\Test.docx" The starting point is a Process object which is executed by WINWORD.exe . I am not looking for a way that includes parsing
