Print preview comes incorporated in most MFC doc/view apps if you choose it in the wizards.

You have to supply the correct drawing code of course.

But i want to show it at a particular place, so i want to know about class which is related to printprevieewdlg.

Thanks in advance.

How to recognize that mouse doesn't move?

Hi dear,
I want to hide the cursor (for example: after 5 seconds) when the mouse doesn't move anymore.
(Windows Media Player does it when playing movie in the full-screen mode)
On the other words, how can I find when the mouse doesn't move?
Thanks.

If I have a method with two parameters, each with a default value, is there a way to set the value for parameter #2 while somehow still using the default value for parameter #1 when calling the method?

void SomeMethod(int nValue1=0,int nValue2=0);

These should be enough.

I face such problems mainly because my resource dll does not get compiled as dependency is not set on it, it is compiled on request only. So make sure the resource file is getting compiled.

Another possibility to check is whether these styles are being dynamically removed or not.

If you are placing a rich edit control in your dialog, you have to call, AfxInitRichEdit()[^] in the InitInstance() function of you app class.

File Reading and Writing in C++

Shah Ravi6-Jul-08 16:42

Hi! Thanks for helping me. I need to write a program (in C++) that reads the file Employee.dat as input and then outputs to 4 different files which are Managers.dat, Marketing.dat, Developers.dat, and Testers.dat. Each of the output files contains the name of the employees of its category.

The fle Employee.dat contains following data:

Sue Leon 4
Robert Wise 3
Sam Woo 1
Nathan White 3
Suzan Head 2
Henry Williams 4
Christine Mint 1
Kim Leeds 4
Elton Sue 3
Ken Latch 2

I tried to write the program but I don't know what to put in "SWITCH" loop. Here is what i have so far.

#include <iostrean>
#include <fstream>
#include <cstdlib>
#include <string>
using namespace std;

int main()
{
ifstream in_stream;
ofstream out_stream;

in_stream.open("Employee.dat");
if (in_stream.fail())
{
cout << "Input file failed to open.\n";
exit(1);
}

out_stream.open(("Managers.dat", ios::app), ("Marketing.dat", ios::app), ("Developers.dat", ios::app), ("Testers.dat", ios::app);
if (out_stream.fail())
{
cout << "Output file failed to open.\n";
exit(1);
}

string first_name, last_name;
enum department { Managers = 1, Marketing = 2, Developers = 3, Testers = 4 };

im_stream >> first_name >> last_name >> department;
while (!in_stream.eof())
{
switch (department)
{
number '1';
out_stream << "

Are you receiving a preprocessor error with this one?

Or a compiler error with these?

you'll have to take a snapshot of every process, every second (or a time you decide), and compare with the old snapshot to see if you find a new process.

you can try hooking the api that opens the processes to watch it, but it's somehow expensive to develop... there's the oportunity to write a kernel module and watche the processes memory pages, that is more expensive yet...

i don't really much more clues on how to do it, but there are books that goes deep on theese subjects such as "Windows Rootkits: Subverting the windows kernel" and such.

Tab Initialization

6-Jul-08 11:57

A tab control with several tabs was set up on a dialog based project. Everything works fine in switching from tab to tab, but what I would like to do is have a configuration file selected and displayed in the first tab, and then displayed in an edit box in the second tab right after it is displayed.

How does one get the edit box to initialize in the second tab? The OnInitDialog only works when the dialog comes up. Is there a similar function that can be invoked when switching from tab to tab?

Thanks.

I think you need to override OnSelchange() function.

OnSelchange()was in a mytabctrl class for handling the tabs. While in it, I could display an AfxMessageBox("tab2") in the correct tab, but couldn't access any of the edit boxes that were associated with that tab. What I did was send a message from OnSelchange(), and then in the tab2 dialog use
CTab2::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) to trap the message and initialize within the tab2 class.

It works OK, but seems like there ought to be means of directly accessing the tab2 class from within the mytabctrl class.

Thanks for the link. I'll download the file and dig in to it later this evening.
