Thanks. That got things working.

Note: I struggled for a bit until I discovered that the name of my adaptor -- "Intel(R) 82566DM-2..." -- was causing me grief because of the "(R)". Had to change the round brackets to square brackets -- "[R]" -- to get it to work.

Hi Mikey,

If you use the IP Helper library[^] then you can do this:

#include "Iphlpapi.h"
#pragma comment(lib, "iphlpapi.lib")
VOID PrintEthernetSpeeds()
{
	BYTE *pBuf=NULL;
	DWORD dwSize=0;
	DWORD dwResult=0;
	BOOL bConnected=FALSE;
	PMIB_IFTABLE pMIBTable;
	CString str;
	GetIfTable(NULL,&dwSize,FALSE);
	pBuf=new BYTE[dwSize];
	pMIBTable=reinterpret_cast<PMIB_IFTABLE>(pBuf);

	if(NO_ERROR == GetIfTable(pMIBTable,&dwSize,FALSE))
	{
		for(UINT i=0; i < pMIBTable->dwNumEntries; ++i)
		{
			if(MIB_IF_TYPE_ETHERNET == pMIBTable->table[i].dwType)
			{
				char szBuf[MAX_PATH];
				sprintf(szBuf,"%s is %ld\n",pMIBTable->table[i].bDescr,pMIBTable->table[i].dwSpeed);
				TRACE(szBuf);
			}
		}
	}
	delete []pBuf;
}

Best Wishes,
-David Delaune

Thanks! Works great. Modified code slightly for ANSI C. See below ...

Mike.

BYTE *pBuf=NULL;
DWORD dwSize=0;
DWORD dwResult=0;
BOOL bConnected=FALSE;
PMIB_IFTABLE pMIBTable;
UINT i;

GetIfTable(NULL,&dwSize,FALSE);
pBuf=(BYTE *)malloc(dwSize);
pMIBTable=(PMIB_IFTABLE)pBuf;
if(NO_ERROR == GetIfTable(pMIBTable,&dwSize,FALSE))
{
	for(i=0; i < pMIBTable->dwNumEntries; ++i)
	{
		if(MIB_IF_TYPE_ETHERNET == pMIBTable->table[i].dwType)
		{
			printf("%s is %ld\n",pMIBTable->table[i].bDescr,pMIBTable->table[i].dwSpeed);
		}
	}
}
free(pBuf);

plz help me.This is my code

CFile cTestFile;
cTestFile.Open(_T("D:\\Jitu.txt"),CFile::modeCreate | CFile::modeReadWrite);
CArchive ar(&cTestFile,CArchive::store);

m_pRecordSet = new CDaoRecordset(m_pDatabase);
CString strQuery = _T("SELECT * FROM pdpstate ORDER BY pdpstate.setid");
m_pRecordSet->Open(dbOpenDynaset,strQuery,0);
int nRecordCnt = m_pRecordSet->GetRecordCount();
int nFieldCnt = m_pRecordSet->GetFieldCount();

int ntemp = 8;
COleVariant variantTemp;
for(int nCnt = 0; nCnt < nRecordCnt; nCnt++)
{
for(int nfCnt = 0; nfCnt < nFieldCnt; nfCnt ++)
{
variantTemp.Clear();
variantTemp = m_pRecordSet->GetFieldValue(nfCnt );
CString csSetID;
csSetID.Format(_T("%d"),variantTemp.intVal);
cTestFile.Write(csSetID,sizeof(csSetID));
cTestFile.Write(_T(","),1);
}
}
cTestFile.Close();

Actually if you want remove all spaces, then one solution is :-

1. Just open the file in write mode and read all the content of the file in a CStringArray line by line using CArchive.
2. Before setting the content to CStringArray, just use the CString ::Remove function to remove the space.
3. Delete the current file.
4. Create a new file and write the CStringArray content to the new file.

The line is wrong: you should replace it with

cTestFile.Write(csSetID, csSetID.GetLength() * sizeof(TCHAR));

Anyway, I doubt this is what you really want to do (i.e. Are you trying to write a wide-char text file?)?

Hi all,

I have a doubt whether Microsoft Excel will support data of unicode big endian encoded type...

I tried manually pasting unicoded big endian encoded data.. it was showing junk characters...

I have a doubt whether MS Excel 2007 will support Unicode Big Endian type for saving and opening..

Thanks,

RemoveDirectory() only deletes empty directories. To delete files and folders simultaneously, use SHFileOperation().

You may use CImage class for the purpose, see CImage::Load [^] and, for instance, CImage::GetPixel [^].

Just in addition to CPallini's post.

If you decide to use CImage class you will notice that the GetPixel and SetPixel methods are slow. So if you need a fast pixel access you can use this[^] class with combination of CImage class.

Using CxImage[^] library could also be an option. Smile | :)
