I have a printer datafile in a remote computer. I want to print it in my local printer. It's encoded in pcl language, but it's too large to move it into my pc. How can I split large printer data files into multiple pages and print them continuously(one by one)

Hi all,
When any document is opened in ms word then it also creates .tmp file in same folder/temp folder. I want to stop such .tmp file creation.
How can i do that ? Can it be done by some option in MSWord settings? can it be done by writting addin DLL for that? or thru can it be done by writing COM,VC++ application ?
Please Let me know if it is possible? how? by which method?
Any suggestion are welcome.
Thank in advance.

they're automatic recovery files.
go in the tool\options\file location
and either turn off automatic recovery or point it
to a different folder (it's a good feature, but
you may not want it in with your .doc files
because it crowds your directory

Yes u are right.
But Even if i uncheck those option, word still creates .tmp file.
Does anybody has point to this?
How to prevent word from creating ,tmp file, by any means (COM Addin, programmatically etc...)
Thanks

I'm looking for multi-user server source code (tutorial) (C/C++, sockets, no MFC).
Oh, I already know how to do multi connections the windows way (messages sent to my window when data is received), but that's not what I want.
I know there are some here at codeproject but they all use MFC (yuck) and seem alot more complicated then what I've found so far.
I found the original at www.planet-source-code.com (I've re-done and simplified it for this post):
SOCKET ServerSocket;
SOCKADDR_IN server_address;
FD_SET masterSet;
HANDLE ThreadHandle;
DWORD ThreadID;
int RetVal = 0;
DWORD WINAPI acceptingThreadProcedure(LPVOID ServerSocket)
{
SOCKET* Socket = (SOCKET*)ServerSocket;
SOCKET ClientSocket;
while(1)
{
ClientSocket = accept(*Socket,0,0);
FD_SET(ClientSocket,&masterSet);
printf("Client on %d connected\n",ClientSocket);
}
return TRUE;
}
int InitServer()
{
WSADATA wsaData;
WSAStartup(MAKEWORD(1,0),&wsaData);
ServerSocket = socket(PF_INET,SOCK_STREAM,0);
server_address.sin_family = AF_INET;
server_address.sin_port = 4200;
server_address.sin_addr.s_addr = INADDR_ANY;
bind(ServerSocket,(SOCKADDR*)&server_address,sizeof(SOCKADDR_IN));
listen(ServerSocket,5);
ThreadHandle = CreateThread(NULL,0,acceptingThreadProcedure,&ServerSocket,0,&ThreadID);
Sleep(100);
FD_ZERO(&masterSet);
FD_SET pollingSet;
timeval waitTime;
waitTime.tv_sec = 0;
waitTime.tv_usec = 0;
SOCKET clientSocket;
unsigned long BufferSize;
while(1)
{
pollingSet = masterSet;
if(pollingSet.fd_count == 0)
continue;
RetVal = select(pollingSet.fd_count,&pollingSet,NULL,NULL,&waitTime);
if(RetVal == 0)
continue;
for(unsigned int i = 0; i < pollingSet.fd_count; i++)
{
clientSocket = pollingSet.fd_array[i];
recv(clientSocket,(LPSTR)&BufferSize,sizeof(BufferSize),0);
BufferSize = ntohl(BufferSize);
LPSTR Buffer = new char[BufferSize];
recv(clientSocket,(LPSTR)Buffer,BufferSize,0);
Buffer[BufferSize] = '\0';
printf("Client %d: %s\n",clientSocket,Buffer);
delete[] Buffer;
}
}
}
I've been looking for tutorials that teach it with FD_SET and select but havn't found anything yet.
Does anyone know of a good tutorial?
P.S. The reason I'm looking for something more than what I've found is that the current code (above) doesn't have a way to send data back, and I'm not sure how to add that. Also the code just doesn't seem right (tho I don't know what multi-user code looks like), and it uses 100% system resources.
Alright, thank you much.

if I want to export a global operator+ overload, like
String operator+( const String& lhs, const int& rhs );
If I define this in a header, like
__declspec( dllexport ) String operator+( const String& lhs, const int& rhs );
and then implement this in a .cpp like
__declspec( dllexport ) String operator+( const String& lhs, const int& rhs )
{
return ....
}
it compiles and builds the DLL fine. When I link to the dll from an exe, however, I get linker errors claiming "String operator+(..." isn't defined.
What am I doing wrong? Is it not possible to have the implementation in a .cpp file?
Thanks !

May that be a problem of linker decoration, calling convention mismatch? Could using extern "C" solve your problem?

Well I did try the "extern" keyword and that didn't make any difference. I'm really at a loss, and I guess I'll just have to try and put the impl in the header, which I really didn't want to have to do.

Is the __declspec( dllexport ) hard coded in the header?
If so you might try forward declaring the prototype with
dllimport and try that.
Thank You

nope, I am using the traditional DLL_API kind of macro to shift it to import or export as the case may be.

How to include a .lib file in a activex control project?
I want to create a ocx project which uses some dll and lib file.
There is not link option in project menu.
How to do it?

char myOldFileName[99];
char myNewFileName[99];
myOldFileName = "myfilename.sch"
Here's what I need to do:
I take myOldFileName which = "myfilename.sch"
and set myNewFileName = "myfilename.cfm"
then I need to take myNewFileName and set it = to myfilerocks.cfm
the problem is I get little smiley face characters when I do it
so it becomes myfilenamerocks .cfm (not really that smiley face, the ascii one).
I'm using Visual c++ 4.2.

you can't assign stuff like that in C/C++;
try using either strcpy (bad, IMHO), or std::string (good). If you use std::string, it becomes:
#include <string>
std::string myOldFileName;
std::string myNewFileName;
myOldFileName = "myfilename.sch"
myNewFileName = "myfilename.cfm"
if Visual c++ 4.2 doesn't support STL (I have no idea if it does, though I'd love to know why you are stuck using it ), then you'll need to use strcpy (or even memcpy).
Cheers
Jim

Jim,
the problem is 4.2 doesn't use strings. (as far as I can tell anyway)
I used strncpy to set mynewfilename = myoldfilename,
the problem I'm having is then manipulating mynewfilename.
I know in newer versions I can do an object.replace(...) but not on 4.2
I've broken it down by position number (ex: myoldfilename[x]) but that's where I start getting the smiley faces for some, but not all, of the characters.
----------------
why are we still on 4.2? because years ago someone decided it would be
too much work to upgrade to a newer version. Since then it's never been a priority. Luckily, that's about to change. In fact, I've got .net training next week and with any luck will soon leave 4.2 behind.

Cool. Well if after that you still do C++, I can't emphasize enough how worthwhile it would be to replace this kind of code with std::string (or std::wstring if you need wchar_t support). It's just much less hassle and looks cleaner too.

I got it figured out.
null terminated string was the cause
needed to set mystring[x] = 0;
and voila! no more smiley faces on the screen.
Just a big smiley face on me.

I really need some help with this one. I am new to the computer world, I am a college student and I am currently taking a course that covers object oriented programming. I needed help in trying to figure out how to start it. If anyone reads this please help me. Thank you for taking the time to read this. Below I have provided the criteria for doing the assignment and see if anyone may know how to do it, because I DON'T!!!.
Objectives:
You are to write a program that simulates the operation of a calculator. The calculator will perform the simple arithmetic operation of add, subtract, multiply, and divide. The user will be allowed to invoke methods to get data from the user (i.e., the operands), perform a given type of calculation, and to display the result.
Specific Instructions:
1. Define the class -- Calculator
a) Data members: Operand1, Operand2, and Answer -- all of type float.
b) Methods: Constructor, GetData, Add, Subtract, Multiply, Divide, and ShowAnswer -- all void return types.
c) Data members should be private, but all methods should be public
2. Constructor -- Calculator
a) The constructor should provide for two arguments of type float: Op1, and Op2
b) Give default values of zero to Op1, and 1 to Op2 in case the user passes no arguments when objects are created.
c) The constructor should assign the values of Op1 and Op2 to Operand1 and Operand2, respectively.
3. Each method that does a calculation should store the answer in Answer but not do any output itself.
4. The ShowAnswer method is responsible for displaying the calculated result of the last calculation.
5. Create four objects, Problem1, Problem2, Problem3, and Problem4 as follows:
Calculator Problem1(3,7), Problem2(8,3), Problem3, Problem4(17,5);
6. Do the following method calls: (YOU MUST FOLLOW THESE INSTRUCTIONS!)
a) For Problem1, call the method that will add the default values, and call the method to display the result.
b) For Problem2, call the method that will subtract the default values, and call the method to display the result.
c) For Problem3, call the method to get data, provide values of 7 and 3, multiply them, and display results.
d) For Problem4, call the method that will divide the first operand by the second, and display the results.
