Description: 打开一个TXT文件并显示在EDIT控件中
步骤:
1.新建一个基于对话框的工程，名称为ReadFile
2.在界面上添加一个按钮(IDC_BUTTON1)和一个文本编辑(IDC_EDIT1)
IDC_EDIT1的属性:多行、可下拉滚动条.
3.编辑按钮触发事件(void CReadFileDlg::OnButton1())
void CReadFileDlg::OnButton1()
{
// TODO: Add your control notification handler code here
CString sFileFilter="*.hex|*.hex"
CString sFileName
CFileDialog fDlg(true,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,sFileFilter,NULL)
fDlg.DoModal()
sFileName=fDlg.GetFileName()
if(sFileName!="")
{
CFile file(sFileName,CFile::modeRead)
int nFileLength=file.GetLength()
char *buffer
HGLOBAL hgl=::GlobalAlloc(GMEM_MOVEABLE,nFileLength+1)
buffer=(char *)::GlobalLock(hgl)
file.Read(buffer,nFileLength)
SetDlgItemText(IDC_EDIT1,buffer)
::GlobalUnlock(hgl)
::GlobalFree(hgl)
}
UpdateData(false)
}
-Open a TXT file and displayed in the EDIT control steps: 1. Create a new dialog-based project, known as the ReadFile2. In the interface to add a button (IDC_BUTTON1) and a text editor (IDC_EDIT1) IDC_EDIT1 properties: multi-line, can be drop-down scroll bar .3. Edit button trigger events (void CReadFileDlg:: OnButton1 ()) void CReadFileDlg:: OnButton1 () (//TODO: Add your control notification handler code here CString sFileFilter =*. hex |*. hex CString sFileName CFileDialog fDlg (true, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, sFileFilter, NULL) fDlg.DoModal () sFileName = fDlg.GetFileName () if (sFileName! =) (CFile file (sFileName, CFile:: modeRead) int nFileLength = file.GetLength () char* buffer HGLOBAL hgl =:: GlobalAlloc (GMEM_MOVEABLE, nFileLength+ 1) buffer = (char*):: GlobalLock (hgl) file.Read (buffer, nFileLength) SetDlgItemText (IDC_EDIT1, buffer):: GlobalUnlock (hgl):: GlobalFree (hgl)) UpdateData (false))
