Is the problem that you receive part of the total string from the external equipement?
Is the comunication an answer and a response, or full duplex?

Hi All VC++ Programmers,
I am working on a project that is to be migrated from vs-2003 to vs-2008.In my application i have 11 different projects.I am giving all my .lib files into project settings->linker->input->additional dipendencies... But in my project settings->linker->command line i am not getting all the .lib files..i am missing three .lib files....Because of that reason i am getting 362 linking errors,all errors are due to not linking with the missing libraries... the errors are as follows..
fwfipd.lib(fwfpelcp.obj) : error LNK2001: unresolved external symbol "public: virtual class ATL::CStringT<char,class StrTraitMFC_DLL<char,class ATL::ChTraitsCRT<char> > > __thiscall DblTinyInt::getString(void)const " (?getString@DblTinyInt@@UBE?AV?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@XZ)
......and many other errors.......
can anybody please give some remedy to my problem?thanks in advance.......

Your linker cannot find the DblTinyInt::getString function. You need to find this library or source and add it to your project.

Yes, they have seperate build settings.

You don't know how to add libraries to your project settings? Are you using a Makefile or the graphical interface? Do you have your library paths setup correctly?
Another way to add link libraries is to add them to source files:
#pragma comment(lib, "Your_Library.lib")

hi
i am setting my libraries from project settings->linker->input->additional dependencies...here i am putting my all libraries...
and where do i give full library paths?
|

Vetukuri Raju wrote: where do i give full library paths?
1.) You can add library paths for an single project solution to:
Project settings->General->Additional Library Directories
2.) If you want these libraries to be globally available to all projects you open in Visual Studio you can add them to:
Tools Menu ->Options->Projects and Solutions->VC++ Directories (choose Library files from combo)
I suspect that you need option 1.

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...

Hi how to solve the following error...
CVTRES : fatal error CVT1100: duplicate resource. type:DIALOG, name:PRINTSTATUS, language:0x0409
LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt
It is saying that it is a duplicate resource,but in my .rc file i dont have an id for this dialog.if i am attempting to give any id to this dialog it is giving many other errors....why i am getting this error even though i dont have an id for this perticular dialog...please provide some remedy...

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

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.

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;
}
Best Wishes,

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);

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.

Thanks for reply..
Actually this line is used for writing data to text file.bcoz i m reading data from mdb file and writing it into text file so that purpose this line is used..So plz give me solution ,it's urgent..

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?)?

The inner and outer loop should use different variables.
