reading / writing word files with docfile

[Chris Sadler]

Does anyone have any code that demonstrates how to read and write MS word
files.

Any pointers would be appreciated.

Thanks

Microsoft Developer Network Library Edition
Microsoft Office Development
Office
Microsoft Office 97 Binary File Formats
Microsoft Word 97 Binary File Format
and when you decide that's too ugly, you can use StgOpenStorage,
IStorage::OpenStream, IStream::Seek and IStream::Read to read the data.

#include <windows.h>
#include <stdio.h>
// Extracts text from a simple only-text document.
int ExtractTextFromMSWordDoc(const char *filename,
char *buf,
int maxBufSize,
int *ReturnLength,
int *Status) {
// Translate filename to UNICODE...
WCHAR wcFilename[1024];
int i = mbstowcs(wcFilename, filename, strlen(filename));
wcFilename[i] = 0;

// Open document as an OLE compound document...
IStorage *pStorage;
HRESULT hr = ::StgOpenStorage(wcFilename, NULL, STGM_READ | STGM_SHARE_DENY_WRITE, NULL, 0, &pStorage);

if(FAILED(hr)) {
return -1;
}

// Open the data-stream where Word stores the data...
IStream *pStream;
hr = pStorage->OpenStream(L"WordDocument", NULL, STGM_READ | STGM_SHARE_EXCLUSIVE, 0, &pStream);

if(FAILED(hr)) {
pStorage->Release();
return -1;
}

// Seek to the entry in the FIB where the
// offsets for the text is stored...
LARGE_INTEGER offset;
offset.QuadPart = 0x18;
//DWORD count;
pStream->Seek(offset, STREAM_SEEK_SET, NULL);

// Read starting & ending offsets...
long start, end;
pStream->Read(&start, sizeof(long), NULL);
pStream->Read(&end, sizeof(long), NULL);

// Seek to starting offset...
offset.QuadPart = start;
pStream->Seek(offset, STREAM_SEEK_SET, NULL);

// Read text into buffer...
int size = min(end-start, maxBufSize-1);
pStream->Read(buf, size, NULL);

// Let go of our IStreampointer...
pStream->Release();

// Let go of our IStorage pointer...
pStorage->Release();

*ReturnLength = size;

return 0;
}

do you have an example of reading a exel file (.xls)
Thanks,
Lee.

ODBC via SQLAllocEnv, SQLAllocConnect, SQLConnect, SQLSetConnectOption,
SQLAllocStmt, SQLSetStmtOption, SQLExecDirect, SQLBindCol, and SQLSetPos
will write an XLS. You should be able to adapt SQLGetData to read one.
