Hi CPallini,

It should be my description issue.

What I compare is, making an interface "dispinterface" in IDL, comparing with an iterface implementing IDispatch or dual. Have I made myself understood? Smile | :)

You can use FindFirstFile/FindNextFile APIs or if using MFC you can use CFileFind class to find all the files in the folder and use CopyFile API to copy files one by one..
Does it help??

Thx's sir i am abel to copy file through this code

CopyFile("source Path", "Destination Path",TRUE);

.So do you think it is necessary to use

FindFirstFile/FindNextFile

.

Plz help me

You said that you need to copy all the files from the folder. So you have to use FindFirstFile/FindNextFile API to list all the files in that folder.

Here is sample code for listing all files in the directory

I hope it helps..

You will not be able to copy directory using CopyFile.
Either you can use FindFirstfile/FindNextFile and copy file by file manually.

Or

You can use SHFileOperation API.
Here is good article by Michael Dunn for SHFileOperation
Wrapper for SHFileOperation[^]
I hope it helps..

Use FindFirstFile/FindNextFile.

Somethings seem HARD to do, until we know how to do them.

As implicitely suggested by sashoalm, you should handle the WM_CTLCOLOR in your dialog.

You can get pixels.
if the R,G,B value are the same, It's not colored.

get and UltraEdit(or other Hex edit), open the pic...

How can I calculate the speed of file transfer using recv function on client? the code a client presented as below

How can I calculate the speed of file transfer using recv function on client?
The code a client present as below,

__int64 iFileSize=0;
__int64 iPos=0;

//Get the size of file from server
char *sizeBuff[64]={'\0'};
DWORD dwRead=recv(Socket,sizeBuff,64,0);
iFileSize=_atoi64(sizeBuff);

char readBuff[BUFFSIZE]={'\0'};
while(iPos<ifilesize)>
{
dwRead=recv(Socket,readBuff,BUFFSIZE,0);
//here write to local file
iPos+=(__int64)dwRead;
//Question here: how can I carry out the speed of reveiving? as k/s or kb/s
}

//Thanks so much and I'll appreciate it

What are you having trouble with?

You show the necessary calculation in your comments:

amount of data divided by elapsed time.

//to Mark Salsbery

//I tried to calculate the speed like that:

long bClock=GetTickOut();//get the system clock before excuting the next code
dwRead=recv(Socket,readBuff,BUFFSIZE,0);
WriteFile(handle,readBuff,dwRead,&dwWritten,0);
long eClock=GetTickOut();//retrieve the system clock once again
long vClock=eClock-bClock; //carry out the variance between eClock and bClock;
long speed=(long)((double)(dwRead*1000)/(vClock*1024));

//puporsed to calculate the speed as k/s here
//But I got nothing,It always show me 0
//I wanna know why and what else other solution to solve this problem.
//Thanks a lot

Shouldn't that be something more like this:

// Divide bytes read by 1024 to get KB (multiply that by 8 to get Kb)<br />
// Divide milliseconds by 1000 to get seconds (assuming your tick count is in milliseconds)<br />
<br />
long speed = (long)(((double)dwRead / 1024.0) / ((double)vClock / 1000.0));

Also just doing it once isn't going to be informative - you're just measuring
how fast the recv() function can remove bytes from it's internal buffer.

You need to make cumulative measurements over many recv() calls.

Accumulate the speed over a period of time... for example over one second (bytes/sec):

void CSocketClient::OnReceive(int nErrorCode) //called when data is available
{
  //... more code here
  int nBytesRead = ::recv(&m_socket, pBuffer, nBufferLen, 0);
  if(nBytesRead && nBytesRead!=SOCKET_ERROR) m_nBytesReceived += nBytesRead;
}

void CSocketClient::OnTimer() //called every second
{
  m_nTransferSpeed = m_nBytesReceived;
  m_nBytesReceived = 0;
}

int CSocketClient::GetTransferSpeed() const { return m_nTransferSpeed; }

Hope it helps.

Bitmaps on Tabs of TabControl

Hi, I'm working on a tab control and i would like to place the bitmaps on each tab of the tab control. I did use "InitImageList" function yet there was no big help and an error message says CTabCtrl doesnt have "InitimageList" function. Please advice me how to proceed and i would also wish to have my tabs on the left side of my dialog box , how is it possible?? Becoz in properties we can change them from top position or bottom position.
