由 百般思念 提交于 2019-12-08 14:29:46
问题 I try to load text (formatting in RTF ) to my rich text control but it doesn't work. I've even tried to use WriteFile((HANDLE)dwCookie, myBuff, cb, (DWORD*)pcb, NULL); instead of *pcb = rtf->readsome((char*)pbBuff, cb); void CreateRichEdit(HWND hwndOwner, int x, int y, int width, int height, HINSTANCE hinst) { LoadLibrary(TEXT("Msftedit.dll")); edittext = CreateWindowEx(0, TEXT("RICHEDIT50W"), TEXT("Type here"), ES_MULTILINE | WS_VISIBLE | WS_CHILD | WS_BORDER | WS_TABSTOP | ES_AUTOVSCROLL |

Hiding caret in RichEdit winapi

由 廉价感情. 提交于 2019-12-07 15:30:38
I would like to hide a caret from a RichEdit(50W) with ES_READONLY style specified. It's pretty confusing for the user, when the caret is blinking and the user can't type. I tried to hide the caret using HideCaret() function, however it doesn't work for me with following code: LRESULT CALLBACK ChatMessaegsSubclassProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) // Subclassed control { LRESULT ret = CallWindowProc(WndProc_ChatMessages, hwnd, msg, wParam, lParam); switch(msg) { //Also tried with EN_SETFOCUS case WM_SETFOCUS: { ret = CallWindowProc(WndProc_ChatMessages, hwnd, msg, wParam,

问题 I added a read-only rich edit 2.0 control to my dialog (code is using C windows API, the dialog is created by using function DialogBox) At the dialog call back, at the WM_INITDIALOG, I add the following code to enable url detection and also enable the event ENM_LINK is sent to the parent dialog instead of the rich edit control itself: LRESULT mask = SendMessage(hWndText, EM_GETEVENTMASK, 0, 0); //hWndText is rich edit control SendMessage(hWndText, EM_SETEVENTMASK, 0, mask | ENM_LINK); :

Display of Asian characters (with Unicode): Difference in character spacing when presented in a RichEdit control compared with using ExtTextOut

由 雨燕双飞 提交于 2019-12-07 04:02:46
问题 This picture illustrates my predicament: All of the characters appear to be the same size, but the space between them is different when presented in a RichEdit control compared with when I use ExtTextOut. I would like to present the characters the same as in the RichEdit control (ideally), in order to preserve wrap positions. Can anyone tell me: a) Which is the more correct representation? b) Why the RichEdit control displays the text with no gaps between the Asian Characters? c) Is there any

Temporaily disabling the C# Rich Edit undo buffer while performing syntax highlighting

由 我与影子孤独终老i 提交于 2019-12-06 09:48:19
问题 I already have a pretty decent syntax highlighter in my Rich Edit control but I have one final problem before it is fully useful: Whenever I run the syntax coloring it records those coloring actions in the undo buffer, which I do not really want. Is there any way to temporarily disable recording undo actions so that after a coloring the user can press undo and it will just undo the user's own actions and not the automated syntax highlighter? I don't think I have the time to implement the

contentEditable cursor position/style in FireFox

由 久未见 提交于 2019-12-06 01:11:05
问题 I'm having trouble using contentEditable in FireFox 3. I have a problem where the cursor will appear above or only partially in the div after I click in it (until I start typing at which time it behaves correctly). Any ideas on how I can stop this from happening? HTML: <html> <head><title>Test Page</title></head> <body> <div id="editor" style="position:absolute; left:157px; top:230px; width:120px; height:30px"> <div id="input" style="width:100%; height:100%; border:1px solid black; outline

Why am I getting RichEdit line insertion error when I call Delete in OnChange event?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-05 18:27:46
I've googled and checked many places for a solution, but all cases I found differed or involved something more advanced than simply adding or deleting lines. Basically, I want to make a sort of scrolling rich edit (alternative would be moving the caret to the bottom, which I already found a solution for). I'm adding lines to it and checking Lines.Count with the OnChange event of the rich edit and as soon as it reaches value greater 15 I want to call Lines.Delete(0) , however I get the error: RichEdit line insertion error Can someone tell me what am I doing wrong here ?
