its better you install the SDK, you will then keep looking for other header fiels and other dll and libs.

Hi there, Iv wrote a program to transfer files between a cleint and a server,the code works fine for small files but not for large files,im going to post the code wich i hope will help other people trying to do something similar and in hope that i can get some suggestions on how to improve the code iv wrote.

{
char *buffer;
char sizebuf[20] = "";
long SizeOfFile = 1;
long BytesSent = 0;

std::ifstream file ("C:\\Windows\\Example.exe" std::ios::in | std::ios::binary | std::ios::ate);
if (!file)
{
MessageBox(NULL,"Error Opening File",NULL,MB_OK);
}
SizeOfFile = file.tellg(); //get size of file
file.seekg (0, std::ios::beg);
ltoa(SizeOfFile,sizebuf,10); //put sizeoffile in char buf
send(newsock,sizebuf,strlen(sizebuf),0);//send the size to client
buffer = new char[SizeOfFile];
file.read (buffer,SizeOfFile).eof();
do{
BytesSent = send(newsock,buffer,SizeOfFile,0);
}while(BytesSent < SizeOfFile);

Here i dont know if i should be reading blocks of the file into the buffer in the do while loop or out side of the loop and i dont know how to equally divide the file into "Chunks" to be sent separatly and rebuilt the other side help would be appriciated

{
char buffer[20];
long SizeOfFile = 0;
char* recvfilebuf;

recv(Socket,buffer,sizeof(buffer),0); //recv size of file to be d/l
SizeOfFile = atol(buffer);
ZeroMemory(buffer,20);

recvfileBuf = new char[SizeOfFile];
std::fstream file (C:\\Example.exe, std::ios::out | std::ios::binary | std::ios::ate); //Dir of our new .exe
if (!file)
{
MessageBox(NULL,"Error Opening File",MB_OK);
}

do
{
recieved = recv(Socket,recvfileBuf,SizeOfFile,0); //recv actuall file
file.write(recvfileBuf,recieved).eof(); //write new file

}while(recieved < SizeOfFile);
ZeroMemory(buffer,20);
}

I know there is a better way of doing what im trying to do but its hard without extensive know how on the subject..Any comments would be greatly apriciated

Thankyou

Why not? What are you (not) seeing that is wrong?

thes3cr3t1 wrote:
file.read (buffer,SizeOfFile).eof();

What is this?

Yes you should, unless you are reading all of the file at once.

It looks like you typed this off the top of your head, because the example would not work as is.

The do while for recieving and writing data will probably go into an infinite loop, because recieved will probably never be greater than or equal to SizeOfFile. recv may only be reading the amount of data that is currently available (per documentation), that may be less than the whole file, so you need to read it in chunks and use a seperate variable to keep track of the total amount read.

Some thing like the following should work:

int written;
int recieved_so_far = 0;
do {
recieved = recv(...);
if( recieved == 0 ) {
    // there was no data available at this time
    // you may want to go to sleep for a fraction of a second (see Sleep())
    continue; // go back to start of loop and try again.
}
else if( recieved < 0 ) {
    // whoops it is an error code (see documentation)
    // figure out how to handle it
}
recieved_so_far += recieved;
// file.write(recfileBuf,recieved);
written = file.sputn(recfileBuf,recieved);
if( written != recieved )
   // whoops! that should not have happened
} while( recieved_so_far < SizeOfFile );

Good luck!

CDHtmlDialog (COM?): memory leak, wrong 'this' pointer, ect

balage24-Jan-06 22:44

Hi!

I have some problems with this class. This class is implemented in a dll and it is called in own thread (GUIThread()). In GUIThread(): OleInitialize(NULL) is called, after main dll function (dllMain()) is called, and then dllMain() exits OleUninitialize() is called.
So:
- The 'this' pointer is not the same, for example, in OnInitDialog() and in a hmtl event-handling function, and I would like to refer to 'this' pointer, the application is aborted with a memory error.
- If GUIThread() is finished and I would like to run this thread again, the program aborted with a memory error, or some thread, which were started by MFC when CHtmlDialog class was used at first, isn't finished and there will be memory leaks.
Any ideas?
