winsock , can't receive the file data .

[thejackal]

hi there ,

i'm new c++ winsock programmer , i'm writing c++ code using Winsock so i can send a text file from client to server , the problem is the server is not receiving the full content of the txt file if it was too long , i.e: if the file contain "hello" this may work ,but if the file contain "hello how are you? fine ? " -> this don't arrive to the server and no file is even created !

please help me receiving the full file , here is the code :

Server Receive Code :

  int Size;
    char *Filesize = new char[1024];

    if(recv(ClientSocket, Filesize, 1024, 0)) // File size
    {
        Size = atoi((const char*)Filesize);
        printf("File size: %d\n", Size);
    }

    char *Buffer = new char[Size];

    if(recv(ClientSocket, Buffer, Size, 0)) // File Binary
    {
        FILE *File;
        File = fopen("E:\\file2.txt", "wb");
        fwrite((const char*)Buffer, 1, Size, File);
        fclose(File);
    }

	std::cout<<"File Receive done ";

Client Send Code :

 

	//Send A File ///
	FILE *File;
        char *Buffer;
        unsigned long Size;

        File = fopen("E:\\file1.txt", "rb");

    //File = fopen("file1.txt", "rb");
        if(!File)
        {
            printf("Error while readaing the file\n");
           
        }

    fseek(File, 0, SEEK_END);
        Size = ftell(File);
        fseek(File, 0, SEEK_SET);

    Buffer = new char[Size];

        fread(Buffer, Size, 1, File);
        char cSize[MAX_PATH];
        sprintf(cSize, "%i", Size);
		printf("file size is %s ",cSize);
        fclose(File);

        send(ConnectSocket, cSize, MAX_PATH, 0); // File size
        send(ConnectSocket, Buffer, Size, 0); // File Binary
        free(Buffer);

I would first check the return values of your socket calls. Are you getting any error codes?

[thejackal]

no i don't get any error code , let me post you an image of the client data before send and the server data received .
