I have a small challenge I need some help with. I have a
CScrollView derived class that displays columns, and each column has a header associated with it. I want the headers to always be displayed even when the view is scrolled. Thanks in advance for your response.

A solution could be to use two views in the frame, one for the data and one for the column header.

Hi,
After reading article at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvc60/html/redistribvc6.asp ... I am very surprise that we have to do a lot of steps to distribute a single Visual C++ application working with MS Access & DAO
Is there any simple way to include every thing in a single CD? Here are what I have:
a) An Visual C++ 6.0 application: Trial.exe
b) A Trial.mdb that is needed for the Trial.exe (MS Access2000)
What I need more to put in the package and install them in a PC that has Window98 (or later) without having MS Access & Visual C++?
I do know one thing, if I install in that PC ---> Visual C++ only with Access Database option ... it will work! How can I do a similiar task without installing Visual C++?
Thanks for any help

Hi All,
I have a vexing problem related to CListCtrls within nested CPropertysheets.
Very standard stuff here, the invisible CListCtrl is on CPropertyPage along with several visible CButton controls.
DWORD dwStyle = LVS_REPORT | LVS_SHOWSELALWAYS | WS_CLIPCHILDREN |
WS_CHILD | WS_VISIBLE | WS_GROUP | WS_TABSTOP | LVS_EDITLABELS ;
DWORD dwEXStyle = LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | WS_EX_CLIENTEDGE;
It must be obvious but I cannot see it.
If there are any kind souls out there - please help
Regards In Advance
Bonnie

Do you have a group box on the property page as well? If you do, check the tab order as it can hide any controls under it. Try putting it before/after the control being hidden in the tab order.

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?)
