What is the way C++ operates the clipboard?

This article mainly introduces "how C++ operates the clipboard application". In daily operation, I believe many people have doubts about how C++ operates the clipboard application. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "what is the way C++ operates the clipboard application?" Next, please follow the editor to study!

The following describes how C++ operates the clipboard, mainly writing and obtaining data. The operation of the clipboard can be seen as a way of inter-process communication.

1. Create a new project ClipboardTest based on dialog box MFC in VC++ (6.0-9.0)

2. Add two editing controls (IDC_EDIT_SEND and IDC_EDIT_RECV) and two buttons (IDC_BTN_SEND and IDC_BTN_RECV)

3. Add the code for IDC_BTN_SEND to write data to the clipboard

If (OpenClipboard ()) / / Open clipboard {CString str; HANDLE hClip; char* pBuf; EmptyClipboard (); / / clear clipboard GetDlgItemText (IDC_EDIT_SEND,str); / / get data in IDC_EDIT_SEND / / write data hClip=GlobalAlloc (GMEM_MOVEABLE,str.GetLength () + 1); pBuf= (char*) GlobalLock (hClip); strcpy (pBuf,str); GlobalUnlock (hClip); / / unlock SetClipboardData (CF_TEXT,hClip) / / format / / close the clipboard CloseClipboard ();}

4. Add code to read clipboard data for IDC_BTN_RECV

If (OpenClipboard ()) / / Open the clipboard {if (IsClipboardFormatAvailable (CF_TEXT)) / / determine whether the format is what we need {HANDLE hClip; char* pBuf; / / read data hClip=GetClipboardData (CF_TEXT); pBuf= (char*) GlobalLock (hClip); GlobalUnlock (hClip); SetDlgItemText (IDC_EDIT_RECV,pBuf); / / data is displayed in IDC_EDIT_RECV CloseClipboard () }} at this point, the study of "how C++ operates the clipboard application" is over.
