Introduction
TapEditor is just an editor application to show how to using the new documented msfedit.dll to support our editor to add a table.
There are some new features that the rich edit control has supported in this new version. Table is one of them. Now we use the code below to help your editor support table. For more information about richedit control 4.1, you can follow this link.
Using the code
- Create an editor where the base View is
CrichEditView
.
- In the
InitInstance()
function of your editor, add the following code to load msfedit.dll:
if (LoadLibrary(_T("MSFTEDIT.DLL")) == NULL)
{
AfxMessageBox(_T("Could not load the RichControl Dll."),
MB_OK|MB_ICONEXCLAMATION);
return FALSE;
}
- In the
PreCreateWindow
function of the View, specify like this to tell the View to create the class RICHEDIT50W
of the new richedit control version: BOOL CTapEditorView::PreCreateWindow(CREATESTRUCT& cs)
{
BOOL bRes = CRichEditView::PreCreateWindow(cs);
cs.style |= ES_SELECTIONBAR;
cs.lpszClass = szClassRE;
return bRes;
}
Please add this code in the top of the CPP View file.
static const TCHAR szClassRE[] = TEXT("RICHEDIT50W");
- Now to insert table, add a new function like
OnInsertTable
for example, and specify code like this: void CTapEditorView::OnInsertTable()
{
CInsertTableDlg dlg;
if(dlg.DoModal() == IDCANCEL)
return;
int rows = dlg.m_nRows,
cols = dlg.m_nColumns;
CString s = "{\\rtf1";
CString s = "{\\rtf1";
CString sTable = s +
"file://ansi//ansicpg1252//deff0//deflang1033{//fonttbl"
"{\\f0\\froman\\fprq2\\fcharset0 Times New Roman;}"
"{\\f1\\fswiss\\fcharset0 Arial;}}"
"{\\*\\generator Msftedit 5.41.15.1503;}\\viewkind4\\uc1";
CString row,col;
row = "file://trowd//trgaph108//trleft8//"
"trbrdrl//brdrs//brdrw10 file://trbrdrt//"
"brdrs\\brdrw10 file://trbrdrr//brdrs//"
"brdrw10 file://trbrdrb//brdrs//brdrw10 \\"
"trpaddl108\\trpaddr108\\trpaddfl3\\trpaddfr3";
col = "file:
"brdrw10\\brdrs\\clbrdrb\\brdrw10\\brdrs\\cellx";
CString endcell = "file://cell/";
CString endrow = "file://row/";
int i,j;
int width = 8748/cols;
CString sColw;
for(i=0;i<rows;i++)
{
sTable += row;
for(j=0;j<cols;j++)
{
sTable += col;
sColw.Format(_T("%d"),width *(j+1));
sTable += sColw;
}
sTable += "file://pard//intbl";
for(j=0;j<cols;j++)
{
sTable += endcell;
}
sTable += endrow;
}
sTable += "file://par}";/
#ifdef _UNICODE
LONG len = sTable.GetLength() * 2;
char* data = new char[len + 1];
ClearString(sTable, data);
SETTEXTEX st;
st.codepage = 1200;
st.flags = ST_SELECTION | ST_KEEPUNDO;
SendMessage(EM_SETTEXTEX, (WPARAM)&st, (LPARAM)(LPCTSTR)data);
delete data;
#else
SetTextEX(m_hWnd, sTable, ST_SELECTION|ST_KEEPUNDO, 1200);
#endif
}
- To insert image, do again like above with the new function
OnInsertImage
, with the code below: void CTapEditorView::OnInsertImage()
{
CString sFilter = "All image file|*.bmp;*.jpg;*.gif|"
"Bitmap Files (*.bmp)|*.bmp|JPEG Files (*.jpg)|*.jpg|"
"GIF Files (*.gif)|*.gif|";
CFileDialog dlg(TRUE, NULL, NULL,
OFN_FILEMUSTEXIST|OFN_READONLY, sFilter);
if(dlg.DoModal() == IDOK)
{
CTapBitmap bmp;
if(bmp.Load(dlg.GetPathName())==FALSE)
{
AfxMessageBox(_T("Could not load image."));
return;
}
CEnBitmap enBitmap;
CBitmap Bitmap;
if (enBitmap.Attach(bmp.GetBMP(), 0))
{
Bitmap.DeleteObject();
Bitmap.Attach(enBitmap.Detach());
IRichEditOle *pRichEditOle;
pRichEditOle = GetRichEditCtrl().GetIRichEditOle();
HBITMAP hBitmap = (HBITMAP)Bitmap;
if(hBitmap)
{
CImageDataObject::InsertBitmap(pRichEditOle, hBitmap);
}
}
}
}
- Finally don�t forget to include the headers file.
Include tapex.h file for inserting table.
#include "tapex.h"
And include TapBitmap.h, EnBitmap.h and ImageDataObject.h for inserting image.
#include "TapBitmap.h"
#include "EnBitmap.h"
#include "ImageDataObject.h"
This example applies for VC++ 6 so you don�t need to add the richedit.h header file if you don�t want to have errors.
If you use Visual Studio .NET or VC++ 7, you don�t need to use tapex.h and tapex.cpp files. For more information, please use this link.
