1.用SetWindowText设置文本内容并换行： 其中控件属性设置： MultiLine=true; want Return = true; strMsg+=s+"/r/n";// 用/r/n换行。 //获得EDIT CEdit* pBoxOne; pBoxOne = (CEdit*) GetDlgItem(IDC_EDIT1); //付值 pBoxOne->SetWindowText( _T"FOO" ); //取值 CString str; pBoxOne->GetWindowText(str); GetDlgItem(IDC_EDIT1)->SetWindowText( _T("FOO") ); 也可以 //取值 CString str; GetDlgItem(IDC_EDIT1)->GetWindowText(str); EditControl是在MFC对话框中最频繁的使用的控件之一 VC++2005提供EditControl的属性和控件事件操作简单方便 1只允许输入数字 如果设置EditControl中只能输入数字,在VC6.0中需要编写一个派生类来达到目的,而在VC++2005下只需要在属性对话框中将 Number的属性值设 为True就可以了. 2获取EditControl的内容 两种方法 第一种,利用MFC应用程序向导生成一个基于对话框的应用程序

win32 c++ detecting 'enter' in a edit control withot subclassing?

由 我们两清 提交于 2019-12-10 14:58:35
问题 Basically I want an Enter to trigger a message I can catch when a edit control har focus and a user press enter. All solutions online seems to be about subclassing, but I was wondering if there was another way around it? For example, my button has an identifier ID_BUTTON_SEND. Here's how I imagine it; case WM_COMMAND: switch (LOWORD(wParam)) case ID_BUTTON_SEND if ('enter was pressed') do this else default ...you get the idea :) I've read the http://support.microsoft.com/kb/102589 but frankly

由 旧城冷巷雨未停 提交于 2019-12-10 14:53:56
问题 Although the documentation says that this bug is fixed (see: Add the navigation flag), I am experiencing the same problem. From my application I want to add new Android contact, and after the saving is completed I want to get back to my application (the activity that called the insert new android contact intent).

PDF: How can I override/fix searchable text in a scanned image + OCR file?

由 纵然是瞬间 提交于 2019-12-10 13:53:06
问题 I'm trying to create an index on a PDF file that I scanned as images from an old original manuscript, then put through character recognition in Adobe Acrobat Pro. The problem is some of the words were spaced funny so the OCR ended up with flaws. I used the find and fix suspects tool but there are still problems. Case in point... The text " FOR EXAMPLE " was spaced funny in the original document (and its image of course) so that Adobe reads it as three words " FOR EX AMPLE " which then results

How to hack on installed perl6 module source?

由 ぐ巨炮叔叔 提交于 2019-12-10 13:27:48
问题 I'd like to be able to view and make changes to the source code of installed (via zef ) perl6 modules. How can I do that? On my system, the module sources are under ~/.perl6/sources/ and there's also some kind of metadata file about the modules in ~/.perl6/dist/ . I can also use zef locate ... to show a module's source path, but making changes directly to the source files doesn't seem to have any effects (i.e., use the module from the REPL doesn't show my changes). I'm guessing it's because
