Visual C++ :: Count / Sentinel Control Loops
Oct 22, 2012
Here is an imgur link to my current homework. [URL] .....
As you can see on there I have them listed on which ones are supposed to be sentinel and which ones are supposed to be count control loops. This is currently what I have:
Code:
#include <iostream>
#include <cmath>
#include <iomanip>
#include <fstream>
using namespace std;
void main() {
int count = 0;
int sum = 0;
[Code] ....
This class has me stumped currently and I am having a hard time breezing through the class at my instructors speed. So I don't want to get too far behind.
Right now this program is giving me an error that opens CMD and gives me infinite lines of "0's".

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

I'm using an animation program. In this program I've simulated a particle system. The particles are flying around at different and varying speeds. I've attached birds to the particles and I want to be able to control each bird's flapping animation based on its velocity; so birds moving faster will be flapping faster.
Initially, the bird's flapping animation is controlled by a parameter that goes from 0 to 100%. So not only do I need to drive the speed at which the animation goes from 0 to 100%, I need to set it on a loop so once it reaches 100%, it loops back to 0%. I'm extremely new to code so I don't think it would be wise for me to even provide a jumping off point, not that I could.

I'm writing a program where a user keeps entering numbers until "0" is entered.Once "0" is entered the loop ends and It displays the mean. Problem is it counts the "0" in the average.
e,g:
Enter number 1: 5
Enter number 2: 2
Enter number 3: 3
Enter number 4: 0
The mean is 2.5. But I want it to only count everything before the "0". (5 + 2 + 3) / 3 = 3.333333

I have a couple of issues that i need to fix.This program finds the average of a number desired by the user.For example if they put in 3 and then 1,2,3 then the average is 2.
First of all my program is supposed to stop if zero is inputed. so if i put in 3 as the number of integers that will be averaged, and then i type 1,2,0 it should stop and not calculate the average.
Also, i need to account for negative numbers. so what should i add to accout for negatives?
#include <iostream>
using namespace std;
double avgVal(int, int);
int main() {
int amountOfCases;
cin >> amountOfCases;
int * numbers = new int[amountOfCases];
[Code] ....

Write a program that will prompt a user to enter a single character, the prompting will continue till a sentinel value is entered. For each character entered perform the following tests and print out a relevant message if the character passes the test. Print out a default message if the character does not pass any of the tests.
Tests that should be in program: Punctuation, Upper Case, Digit, White Space.
Sample Run: “A”, “a”, “7”, <tab>, “?”, “$”
So far I have the following code done. The problem is that when I run the program, the first character is correctly identified. However, every character afterwards is defined as a whitespace character.
#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char input;
char response;
[Code] .....

I get a task: to color the control scrollbar (a gridctrl scrollbar, whatever). In the first attempting I didn't succeded ... So, I started to trying coloring a CListBox scrollbar ... I developed a derived CListBox where I override OnCtlColor:
Code:
HBRUSH CMyListBox::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) {
HBRUSH hbr = CListBox::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
// TODO: Return a different brush if the default is not desired
if(CTLCOLOR_STATIC == nCtlColor) {
pDC->SetTextColor(RGB(200, 34, 0));
[Code] ....
I colored everything, except scrollbars ) ... I attached the app demo ...
I already tried this solution: [URL] ....
but in my case, didn't worked ...
My question is, how can I color the control scrollbar ? It is possible ? If yes, how ?

I want to control my toolbar dynamically.
First I added tool bar with style including TBSTYLE_EX_MIXEDBUTTONS | TBSTYLE_LIST.
Then added the tool bar to a rebar. I added tool tips by handling TTN_GETDISPINFO.
Everything works fine. But when I try to add text to right of the button, the text
gets added but button size is not automatically changing.
The following code is not working .
void SetToolbarText(HWND& hwndToolbar,LPTSTR szText)
{
ATLASSERT(::IsWindow(hwndToolbar));
TBBUTTONINFO tbbi = { 0 };
tbbi.cbSize = sizeof(TBBUTTONINFO);
tbbi.dwMask = TBIF_TEXT;// | TBIF_SIZE;//if I add TBIF_SIZE code will work!
tbbi.cchText = 0;
tbbi.cx = 200;
[Code]...

Im trying to Uncheck a Checkbox control with following code.
Code:
else if((point.x >= (rcRememPass.left - 4) && point.x <= rcRememPass.right) && (point.y >= rcRememPass.top && point.y <= rcRememPass.bottom))
{
if(m_CheckBoxRemem.GetState() == BST_CHECKED)
m_CheckBoxRemem.SetCheck(0);
else
m_CheckBoxRemem.SetCheck(1);
}
Above code snippet is from OnLButtonUp(). Whereas else part working good why the if part is failing to uncheck the box ?.

Special behaviour of a CEdit-control in a CDialogBar:
My CDialogBar is a member of my MDI-mainframe-class. The menu of the mainframe have an item with an accelerator "r".
Now, if I want to type the letter "r" in my CEdit-control, the menu-item (with the accelerator "r") will be called.
How can I type "r" into the CEdit-control? How can I handle it?

In a MDI-app with some toolbars and statusbar I created also a controlbar which can be docked to the left side. My problem now: how do I get the exact height of the controlbar?
In CalcDynamicLayout I set the height for the docked state to the height of the mainframe. This value is too big, but it will work basically.
But how can I get the exact height of the controlbar?

I'm writing an ActiveX control. In one of the functions I'd like the user to be able to pass me a pointer to a buffer that they created which I can then fill with data and return a success/error code. What's the appropriate way to do this? I was thinking about just using an OLE_HANDLE type for the parameter and then casting that to pointer inside the OCX but I'm not sure if that's safe or the right way to do it.

There is a list control in Windows.
When I create a list control I can assign an image list to it with the ListView_SetImageList().
By default, when just created there is no image list assigned as can be checked with ListView_GetImageList().
Now, what should happen when I do following call:
Create list control.
Create an image list
Get the current image list
Assign an image list to list control
Display some items
Assign an old image list to list control.
Does strings on the list control should be indented?

ON_WM_CTLCOLOR(...) works for all the other controls but not the tab control.
Code:
void CEasyWebStoreUploaderDlg::DoDataExchange(CDataExchange* pDX)
{
CDialogEx::DoDataExchange(pDX);
DDX_Control(pDX, IDC_TAB_CTRL, m_tabCtrl);
DDX_Text(pDX, IDC_EDIT_STATUS, m_strServerStatus);
DDX_Text(pDX, IDC_EDIT_UPLOAD_RESULTS, m_strUploadResults);

I need coding this project using while loops and cout/cin.. It is suppose to be one while loop for the whole thing and inside of the first while loop is the second while loop for each sale separately.
You have been asked to write a program to calculate sales totals for a general store. Your program will not know how many products each customer will buy, so your program will have to repeat the process until the last product has been entered (use -1 for Product ID to end each sale). After each sale your program must ask if you want to do another sale (Y - continue, N - end program).
At the beginning of the day, the cash drawer has $500 in it. At the end of the program you must display how much money is in the drawer after handling all your sales transactions.
Input
Your program must take the following input:
- Product ID Number (int)
- Quantity for each item purchased (int)
- Cash Received at the end of the sale
Use the following dataset to determine the price and taxability for each item.
First Sale:
Product ID Price Quantity Taxable
101 $65.00 2 Yes
102 $12.50 1 No
103 $24.50 5 No
104 $38.75 4 Yes
105 $17.80 6 Yes
106 $16.50 2 No
107 $42.85 8 Yes
108 $32.99 2 Yes
109 $28.75 1 Yes
110 $51.55 1 No
Second Sale:
Product ID Price Quantity Taxable
102 $12.50 1 No
103 $24.50 1 No
106 $16.50 1 No
107 $42.85 1 Yes
108 $32.99 1 Yes
109 $28.75 1 Yes
Third Sale:
Product ID Price Quantity Taxable
106 $16.50 4 No
107 $42.85 3 Yes
108 $32.99 1 Yes
109 $28.75 5 Yes
110 $51.55 2 No
Calculating Tax
For those items that are taxable, assume a 7.5% sales tax. Be sure to keep a running total of tax for the each sale.
Getting Started
You must use the starter file provided with this assignment.
What to turn in:
- A copy of your source code
- A printout of your program's output

This is what I try to achieve:
1. Using a CScrollView as the View class type.
2. Using Document/View Architecture.
3. Insert multiple Common Controls such as CEdit, CButton, CListCtrl into the View dynamically.
4. All the Common Controls is base on a template created by user. So I do not know the quantity of the Common Controls.
This is the plan on how to do it:
1. In View OnInitialUpdate(), read the template to get all necessary info on the Common Controls to be create.
2. In View OnInitialUpdate(), create all Common Control. Some Common Control may not have WS_VISIBLE as it may not needed at initial stage.
3. In View OnUpdate(), I need to refresh the Common Control properties such as is its text, position or its visibility. This should happen if Document call UpdateAllView().
My Question:
1. Is this a normal & useable plan?
2. Do I miss other functions for any other messages?
3. Still wondering if I need to involve any coding in OnDraw() for this plan.

How would I go about selecting a subitem in a listview control with just pure Win32 API? I know it's possible with MFC... but I can't use MFC for this project. Right now, when you click on a subitem , it selects only the first column of the row . I used the following by referring internet. But its not working.
HTML Code:
iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED|LVNI_SELECTED);
ListView_SetItemState(hList,iSlected,LVIS_FOCUSED|LVIS_SELECTED,0x000F);

I have a tabbed dialog with a couple of Separate dialogs. I created classes of CDialog for each dialog. Im trying to get the text from the edit control from the tabbed dialog and it appears in a message box when I press a button on the main dialog.
Code:
myDialog test;
test.UpdateData(TRUE);
CString bla = test.m_edit1;
test.UpdateData(FALSE);
MessageBox(bla,bla,MB_OK);
The m_edit is a variable of CString for the edit box
it gives me a error and crashes.
How do I get the text from the other dialogs edit control?
