Visualisation of uft-8 (Polish) not working properly

阅读更多关于 Visualisation of uft-8 (Polish) not working properly

问题 My software supports multiple languages (English, German, Polish, Russian, ...). For this reason I have some language specific files with the dialog texts in the specific language (Encoded as UTF-8). In my mfc application I open and read those files and insert the text into my AfxMessageBoxes and other UI-Windows. // Get the codepage number. 65001 = UTF-8 // In the real code this is a parameter in the function I call (just for clarification) LANGID languageID = 65001; TCHAR szCodepage[10];

How to make a modeless dialog always on top within the app

阅读更多关于 How to make a modeless dialog always on top within the app

问题 I have a modeless popup dialog in my app. I want to make it topmost only within the app it belongs to, not always topmost on the desktop. I have tried to set the first parameter to wndTopMost, but this way the dialog will remain on top on the desktop, which is very bad user experience. I have also tried wndNoTopMost with SWP_NOZORDER parameter, but this only put the dialog in front when its displayed. If I move another dialog/window to the dialog location, the dialog will be buried under the

How Can I Monitor Which Window Currently Has Keyboard Focus

阅读更多关于 How Can I Monitor Which Window Currently Has Keyboard Focus

问题 Is there a way to track which window currently has keyboard focus. I could handle WM_SETFOCUS for every window but I'm wondering if there's an alternative, simpler method (i.e. a single message handler somewhere). I could use OnIdle() in MFC and call GetFocus() but that seems a little hacky. 回答1: So from the way you worded the question I'm inferring that you want to have an event handler which is invoked whenever focus switches between windows. You want to be notified, rather than having to

MFC创建内存映射文件二

阅读更多关于 MFC创建内存映射文件二

知道了原理，现在开始编写具体的函数 1、首先要通过CreateFile()函数来创建或打开一个文件内核对象，这个对象标识了磁盘上将要用作内存映射文件的文件 2、通过CreateFileMapping()函数来创建一个文件映射内核对象以告诉系统文件的尺寸以及访问文件的方式。 3、通过MapViewOfFile()函数通过系统管理将文件映射对象的全部或部分映射到进程的地址空间。 4、操作文件Read/Write，对内存映射文件的使用和处理同通常加载到内存中的文件数据的处理方式基本一样。 5、在完成了对内存映射文件的使用后，还要通过一系列的操作完成对其的清除和使用过资源的释放。 void CMFCApplication1Dlg::OnBnClickedOk()//点击OK { CreateFileMappingEx(); } void CMFCApplication1Dlg::CreateFileMappingEx()//创建映射文件 { DWORD timebegin = ::timeGetTime(); HANDLE fp = CreateFile(TEXT("E://Config.ini"),//这里输入复制的源文件 sourcc GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE

WMI returns information in different formats

阅读更多关于 WMI returns information in different formats

问题 I want to read the hardware configuration to check if a license for my software is valid. Currently, I tried using WMI . This works fine on many machines for several weeks but sometimes, without an obvious reason, WMI returns the hardware configuration in a different format. For example, the serial number of the primary hard disc is converted from characters to a hex string, with all character hex values being swapped pair wise. I figured out that different Windows user types (admin/normal)
