sendmessage

问题 In Google Chrome you can retrieve the text of a JavaScript alert/dialog by simply having the dialog open and doing CTRL-C on the dialog. This will put the text in the dialog into the clipboard. I'm trying to use SendMessage to send CTRL-C to perform a copy on the text of a JavaScript dialog. I've already managed to do this using SendInput but unfortunately that could fail if the window doesn't have focus. I have tried using SendMessage with WM_COPY message but that didn't work for my needs.

问题 I am trying to access a TreeView running in another process. Many of the tree view messages work correctly. However, trying to use the TVM_GETITEM causes that other process to crash. The code below is a simple program that illustrates the crash. To get it to run, you will need some CHM help file. I'm using a CHM help file because hh.exe uses a TreeView control for the table of contents. The goal is to be able to get the a tree node's text. using System; using System.Collections; using System

问题 If I use the code shown below on a vb.net winform the cue banner / watermark appears and behaves as expected (Win7 Pro 32bit VS2008 & 64bit VS2010). However when using the same style of code in a vb.net usercontrol the watermark is not displayed. Anyone got any clues? Some hours later... This is looking like PEBKAC. Works in a test app. with user controls. Both those created at design time and those loaded at run-time, still doesn't work in the main app. though. Still puzzled. Still looking

问题 I am building a test application(testApp) for a legacy MFC based application (MFC-app). I am trying to simulate mouse clicks on the MFC-app using message-passing between them. I was able to do this successfully for bring up dialog boxes from the MFC-app menu. However when I am trying to simulate a mouse click on the View of the MFC -app it doesn't seem to work. The main question I have is whether there are any known limitations in trying to use SendMessage,PostMessage functions to communicate

问题 Windows messages seems a good way to notify an application on Windows OSes. It actually works well, but few question comes up to my mind: How to specify structured data to the lparam of the SendMessage routines (like many message codes does)? I mean... of course the parameter is a pointer, but how the process access to it? Maybe is it allocated by a DLL loaded by the processes sending/receiving the message? Is it possible to share message structured parameters (between sender and receiver)?
