问题 Background I'm working on a C++/MFC application and we've been converting it to display unicode characters to support foreign languages. For the most part this has been successful and unicode characters are displayed correctly. But I've encountered an issue where certain text on certain controls gets cut off. Example Here you can see a button that should display "ログアウト／終了" but gets cutoff and displays an unknown character in it's place. But if I pad the string with spaces it displays fine.

问题 I have a VC++/MFC dialog-based project. In those dialogs, I'm using some sliders with "Notify Before Move" at true. Sometimes, instead of using VS dialog wizard to edit them, I prefer to edit the related .rc file manually in a text editor. The issue is, after editing the .rc file, when I'm trying to open a dialog in VS wizard again, I get this error: "error RC2104: undefined keyword or key name: TBS_NOTIFYBEFOREMOVE" I can still compile the project successfully, but I cannot open the project

问题 I want to post a message to all views. I'm considering get a Document global reference and then implement a method like below void SomeAppDoc::DispatchToAll( UINT msg, WPARAM wP, LPARAM lP ) { //some how get all view's reference //iterate and update each views } What is the effective way? 回答1: The simplest way is to call CDocument::UpdateAllViews, which calls the OnUpdate function of each view attached to the document. If you really need to post a message to each view, rather than call

问题 This question already has answers here : Avoiding “(Not Responding)” label in windows while processing lots of data in one lump (11 answers) Closed 5 years ago . When an application fails to be responsive for 5 seconds (source), Windows can display "(Not Responding)" in the title bar and in some cases show a "not responding" dialog: Ideally, the 5+ second execution should not block the main/event-processing thread, but is there a simple (e.g. 1 liner for MFC C++) way to communicate to Windows

问题 I have strange behaviour of CFileDialog once it is opened. The offered file name looks like it has been truncated, so that only last n characters are visible: image http://ves.fijmovi.com/cpp/CFileDialog_1.jpg As soon as I click on space for name, I get to see the whole file name: image http://ves.fijmovi.com/cpp/CFileDialog_2.jpg So it is not truly truncated, just the beginning position of shown string is not from the start. The complete file name is in this case 36 characters long and part

问题 Hey how do I in MFC get names of all folders? Any examples or which classes should I look into? Any hints will be really appreciated. All I saw is the CFile, which as far as I have seen (though very very little) doesn't looks like it has the ability to do what I want. So please direct me. Thanks 回答1: Look into CFileFind There is an old article in DDJ on how to implement a recursive search using CFileFind . 回答2: A Google search revealed an nice example in: Listing the Files in a Directory It

问题 How to check if a unicode character is full width? I use Win32 / MFC For example, 中 is full width, A is not full width, Ｆ is full width, F is not full width. 回答1: What you need is to retrieve the East Asian Width of the character. You can do it by parsing the EastAsianWidth.txt file from the Unicode Character Database. I could not find a Win32 API that returns this info, but in Python, for example, you can use unicodedata.east_asian_width(unichr). See the Annex #11 for the background of the

问题 I am using CHtmlView to show HTML pages from online into my application.
