Hi
In my project some .obj files are not getting linked...
If i put ProjectSettings->Linker->General:Link Library Dependencies and Use Library Dependency Inputs to:YES then the errors are not included with the .lib files(But showing on .obj files corresponding to the respected libraries.).... If i say NO in the option,i am getting same number of errors,but showing errors in the libraries also.... I have tried your options to get the libraries to be linked.but not done... I will be very helpful if give some remedy to this problem...

Make sure that you check all resource files included in your project. In Visual Studio 2008 you need to go to the Resource tab and right click the YourProject.rc folder. Now choose 'Resource Includes' which will show you all of the included resource files. Check them all for a PRINTSTATUS dialog. You can probably ignore all of the Standard MFC Resources[^] as their resource definitions always begin with AFX_...

HI
Thanks for the reply..I did as you told.I have looked for the resource files..I have my dialog into my project,but my problem is that i dont have any id for that particular PRINTSTATUS dialog in my .rch file.But i am getting the above error...Any code conversion problem?The same code is working successfully in vs-2003.

And when iam ignoring Standard MFC Resources i am getting the errors about menu items saying that unable to find IDR_NEW(one menu item)....etc..
Actually i am ignoring
afxres.rc
please suggest me to solve the perticular LNK error
Thank you

How to get network connection speed WinXP using C & WinAPI

When a network is connected, a balloon pops up from the system tray saying that the connection has been established and indicating the connection speed.

How can I programmatically get this connection speed for a specific interface? I am constrained to using C and the Windows API.

Thanks in advance.
M.

You can use the Performance API (aka, Performance Data Helper) for this. The Object name is Network Interface. The Instance name is machine specific (eg, Intel[R] PRO_100 VE Network Connection - Packet Scheduler Miniport). The Counter name is Current Bandwidth.

Having a bit of trouble. Getting PDH_NO_DATA when calling PdhCollectQueryData. Here is my code:

#define COUNTER "\\Network Interface(Intel(R) 82566DM-2 Gigabit Network Connection - Packet Scheduler Miniport)\\Current Bandwidth"

HQUERY query;
HCOUNTER counter;
PDH_FMT_COUNTERVALUE value;
DWORD counterType;
PDH_STATUS status;

if((status = PdhOpenQuery((LPCSTR)NULL,(DWORD_PTR)NULL,&query)) == ERROR_SUCCESS){
  if((status = PdhAddCounter(query,COUNTER,(DWORD_PTR)NULL,&counter)) == ERROR_SUCCESS){
    if((status = PdhCollectQueryData(query)) == ERROR_SUCCESS){
      if((status = PdhGetFormattedCounterValue(counter,PDH_FMT_DOUBLE|PDH_FMT_NOSCALE,&counterType,&value)) == ERROR_SUCCESS){
        printf("Counter = %f\n",value.doubleValue);
      }else{
        printf("ERROR: PdhGetFormattedCounterValue() failed. Error Code: %X\n",status);
      }
    }else{
      printf("ERROR: PdhCollectQueryData() failed. Error Code: %X\n",status);
    }
  }else{
    printf("ERROR: PdhAddCounter() failed. Error Code: %X\n",status);
  }
  PdhCloseQuery(query);
}else{
  printf("ERROR: PdhOpenQuery() failed. Error Code: %X\n",status);

You are missing the name of your machine:

#define COUNTER "\\\\machine\\Network Interface(Intel(R) 82566DM-2 Gigabit Network Connection - Packet Scheduler Miniport)\\Current Bandwidth"

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;
}

int nFieldCnt = m_pRecordSet->GetFieldCount();

int ntemp = 8;

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,
