ok how do i make a net send program in C++ 6.0, i already know the SYSTEM("net send USER MESSAGE") part, but i want to be able to make USER and MESSAGE variables, where USER would be the name or the place where i would send the message to and MESSAGE would be the message of what was to be sent...YOU CANT DO THIS THE WAY I AM TRYING, an error pops up saying something like USER can not be found on network. also i put in my user name and MESSAGE and the message sent was "MESSAGE", so u cant make a variable for that piece and use it for a large block of message.....please someone help me with this....
here is program i made which doesnt work...
#include <stdlib.h>
#include <iomanip.h>
#include <iostream.h>
int main()
{
char user[20], message[50];
cout << "USER = ";
cin >> user;
cout << "MESSAGE = ";
cin >> message;
system("net send user message");
return 0;
}
//OUTPUT
USER = boycecarter
MESSAGE = hi
An error occurred while sending a message to 'USER'.
The message alias could not be found on the network.
More help is available by typing NET HELPMSG 2273.
Press any key to continue
what do i do???

user and message are constants in your program. You are saying that the user name will be "user" and the message will be "message". Change the whole string to a variable, then try.

|

How about, instead of calling "system" like you are doing so now, doing something like this:
char szFullMessage[256] = {0};
sprintf( szFullMessage, "net send %s %s", user, message );
system( szFullMessage );
Another solution if you want to make a direct function call (much faster), is to call NetMessageBufferSend.

Also you can write:
CString user, message;
CString command;
command.Format("net send %s %s", user.GetBuffer(0), message.GetBuffer(0));
system(command.GetBuffer(0));

ok im only in CS 1 now...and i have pretty n00b like skills compared to u guys...so here----i dont know what "%s" is or what CString user, message is or what command.Format is etc etc etc....my knowledge is prety limited when it comes to what u all are talking about...please let me know what u are doing as u are doing it so i understand it....thanks. and also, i want to make clear that i want USER to be a char variable that someone enters in, and i want MESSAGE to be another char variable that will be the message sent....
ex.
"USER = " cin >> BoyceCarter //my comp address
"Message = " cin >> HEY WHATS UP //also how can u make a message to hold more than just one word.... cause i've tried to do that with my simple net send command ("net send BoyceCarter HI YOU") and all that comes back is HI...not the whole HI YOU part...etc thanks so much

Okay in simple terms
%s is a place holder for whatever you want in it. For example:
line 1. char somestring[] = "really cool";
line 2. sprintf("This is %s", somestring);
The variable somestring (in line 1)is holding the string "really cool".
Line two just replaces the %s with whatever is in the variable.
The go in order. So if you had
sprintf("This is %s and I %s", somestring, anotherstring);
Okay CString. Basically CString is a class that provides support for manipulating strings.
According to MSDN: It is intended to replace and extend the functionality normally provided by the C run-time library string package.
One of the extended functions is the format function. CString is the base class and format is a finction under that class. format allows you to basically setup a string just like using sprintf, where you can use %s or other format variables.
Now I know the other programming guru's out there will complain that I totally did not follow prgramming speaking edict...but how cares just as long as you understand what's going on. I too hate it when these guys speak over my head and I try to keep it at my or some other programmers level so that theres an understanding.
Hope this helps

do anyone know the how to write code for rotating & mirror objects drawn in mfc? instead of drawing them again and again for each rotation.
e.x.
OnDraw()
{
//shape 1
draw the shape 1
//shape2
draw shape 2
//shape3
draw shape3
}
rotate()
{
//rotate shape 1, 45o degrees
//again rotate shape 1
//again rotate shape 1 etc...
}
Is there a code that do this rotating?(example-CRect, which draw the rectangle) something similar to this..
even if not just let me know...
thanks

How to add bar containing icons for commonly-used folders, such as My Computer, Favorites and Desktop in my CFileDialog?
|
|
|
|
|
hi
I don't know how to set icons in CFileDialog.But you can do this using Microsoft Common Dialog controls.
1. Go to Project-->Add to Project-->Components and Control.
2. Choose Registered Activex Controls and select Microsoft Common Dialog Control Version 6.0.
3. Insert this component.(The control will now appear in your tool box.)
4. Place the control in your dialog.
5. Add a member variable for this control.
6. Call the ShowOpen() method.
I hope it's OK for you

but how does the windows calc do it?

It probably uses a custom datatype or a third party library containing one.
Do a search on the web and you should find something suited to your needs. It may not, however, be free.

float f;
double d;
f = 3.1415926535897932384626433832795f;
d = 3.1415926535897932384626433832795;
printf( "%.32f\n", f );
printf( "%.32lf\n", d );
Output:
3.14159274101257320000000000000000
3.14159265358979310000000000000000
double has to be more precise, but the function doesnt show it!

I am looking for a way to get Windows to notify my application when a new USB device is attached or detached from the system.
The ideal solution would be a callback method of some kind, but a small low overhead polling loop could also work.
Thank you.

Windows sends a (rather, a few) WM_DEVICECHANGE message to all top level windows when *anything* in the device list changes.
You can also register for notifications for a specific device class, usign RegisterDeviceNotification()
Note: There's a bug in Win98 that makes UnregisterDeviceNotification crash.
