How do i add multiple document/views to an MDI app??
Is there something else that has to be done other than add additional
document/view classes and AddDocTemplate statements to the InitInstance of the mainframe?
thx

I recently just started to design a tool to help me at work, it works kind of like a Hotel Reservation system. Before we used a program called "Calendar Creator" to manage all the reservations for a given day; however there are a lot of other ways we need to view the data as well. For example sometimes we need to submit reports on how many people are staying in certain buildings and percentages. So I decided to write a tool to manage all this. Everything is going good so far, but one problem.. I need this tool to be able to write all the added entries to a calendar. So I figured I would create a "Calendar View" that would display a calendar with all the added entries. However I soon found that there are no standard or popular calendar controls. So far ever Calendar controls I have seen are really just date pickers. So I figured I would write one myself, however I'm bad at math.. so the question.
1. Do I have to write one myself? (I don't want to re-invent the wheel)
2. If I do have to write it myself, how would I be able to tell that say Feb 10 2003 would be on a Monday?
Any help would be appreciated.
Thank you.

I've worked with the Microsoft calendar controls and they seem to be full of lots of frustrating bugs, so I'd say you're probably better of working from scratch

Hi, is there a simple way to program complex equations in MFC AppWizard(exe)??? For the equation z = z^2 + c, where 'z' and 'c' is (r + i), I was able to program it like this:
//r2 and i2 the user gives the values for
//r and i are the 'x' and 'y' values on the complex plain
//r5 and i5 is the final 'z' value
r3 = (r2 * r2) + (-(i2 * i2));
i3 = (i2 * r2) + (i2 * r2);
r5 = r3 + r;
i5 = i3 + i;
r2 = r5;
i2 = i5;
I need the final answer in complex form (r + i) so I may be able to put those values back into the equation as 'r2' and 'i2'... I want a simpler way to do this so I can use bigger equations like:
z = ((z^5 + c)/(z^3 + z^2 + z + 1)) + sin(z)
Thanks...

Use the Standard C++ complex class.
#include <complex>
std::complex<double> z, c;
z = std::pow(z, 2) + c;
|
|
|
|
|
How would I get the 'r' and 'i' values from the 'z'???
|
|
|
|
|
How would I get the Real and Imaginary values from the 'z'???
|
|
|
|
|
double real, imag;
complex cplx;
T = complex(1.0, 2.0)
real = cplx.real();
imag = cplx.imag();
|
|
|
|
|
It gives me an error saying 'complex' is "undeclared identifier"...
What I need to do after I got 'z' is this:
Final = abs(pow(pow(z[REAL PART], 2) + pow(z[IMAGINARY PART], 2), 0.5));
'double Final' is a single value...
Thanks...
|
|
|
|
|
#include <complex>
using namespace std;
double final;
complex<double> z(1.0, 2.0);
final = abs(z);
pow(x, 0.5) is the same as sqrt(x).
abs(z) where z is a complex number calculates the same value as your formula.
|

|

When I do the calculations this way:
z = (2, 3);
c = (-4, -5);
z = std::pow(z, 2) + c;
Final = abs(sqrt(pow(z.real(), 2) + pow(z.imag(), 2)));
I get a different answer than this:
r2 = 2; i2 = 3;
r = -4; i = -5;
r3 = (r2 * r2) + (-(i2 * i2));
i3 = (i2 * r2) + (i2 * r2);
r5 = r3 + r;
i5 = i3 + i;
r2 = r5;
i2 = i5;
Final = abs(pow(pow(r5, 2) + pow(i5, 2), 0.5));
The second way seems to give me the correct answer... Thanks...

Nevermind, I figured it out... I had "complex<double> z = (2, 3);" instead of "complex<double> z(2, 3);"...

When a modal dialog box is closed using EndDialog does it's parent window recieve a message to notify it that the dialog has closed? I want to update some info in my status bar as soon as the dialog is closed.
Thanks in advance,
Paddy

Thanks for the help. It's non-MFC I'm using. Does this mean that my main window can't do anything until EndDialog is called?

What am I doing wrong? I want to read the names from a file and put them onto a vector of char*......it crashes at the pushback. Each file name is on a different line.
I did a dir/b in dos and got a txt file with a list of file names (a bunch of .bmps) from the directory. I assume theres carriage returns at the end of each line. But maybe not. There are 18 letters in the name08FEB096_9571s.bmp, and carriage return line feed is 1 byte (MSDN).
CFile file;
std::vector<char*> fileVec;
file.Open("c:\\miss\\SImages.txt", CFile::modeRead, 0);
char* pBuf;
char folder[200];
strcpy(folder , "C:\\miss\\");
for (int i = 0; i <96; i++)
{
pBuf = new char[200];
file.Read( pBuf,20);
strcat(folder, pBuf);
fileVec.push_back(folder);
delete[] pBuf;
}
file.Close();

looks like the board ate some of your code. how is your vector defined? (what is it a vector of?)
-c
WWT2D?
|

It was avector of CString. However my problem was that I was using CFile when CStdioFile was more suitable and I had overwritten some buffers, but the poor vector got blamed....
Thanks.

CFile file;
change std::vector fileVec;
to std::vector<string> fileVec;
Move strcpy(folder,"c:\\miss\\");
to For Statement
for (int i = 0; i <96; i++) {
strcpy(folder , "C:\\miss\\");
pBuf = new char[200];
file.Read( pBuf,20);
strcat(folder, pBuf);
fileVec.push_back(folder);
delete[] pBuf;
}

Nobody explained the reason for the crash...Without the unimportant stuff, here is what the code looks like. Do you see the problem?
char folder[200];
strcpy(folder , "C:\\miss\\");
for (int i = 0; i <96; i++)
{
...
strcat(folder, pBuf);
...
}

Yup. I saw finally....my poor "folder" variable was getting concatenated way beyond its allocated space...
Thanks
Appreciate your help,

I have a file with several lines of text (all end with a carriage return). I want to use my CFile object to read these strings into an array of pointers to char. I dont see a anything like GetLine()....if I dont know the length of the text on the line, I dont have a value to give Read() as a count of chracters...
Actually I'm push_backing the strings onto a vector...
