Visual C++ :: Control Structure Outputting Wrong Iterations Via Ints?
Mar 18, 2013
I have this:
Code:
for (chr_min = 0; chr_min <= 24; chr_min += 3) {
strOut = "";
for (ctr_row = 1; ctr_row <=3; ctr_row++) {
switch (ctr_row) {
case 1:
strOut = strOut + Line1.substr(chr_min, 3);
[Code] ....
it is outputting to the shell window, this:
Code:
1
1
1
2
2
3
and that pattern apparently repeats for every iteration that's specified in the outer loop. am I missing something here?

I am getting a string from the consle and that all works fine. I'm expecting a string of number, ie 123456.... I store that fine in my string object. I then need to take each individual number, ie 1, and put it in a vector then take the next number, ie 2, and put that in the next element in my vector.
Everything i've found and does eaither takes the entire string and stores it as an int, or takes the ascii representation of the number and stores that. How do I seperate each individual number and store them seperatly. below is a few different variations i've tried that doesn't produce my desired results.
cout<<"Please type the memory memory frames (numbers 0-9) to be used to simulate the input memory "<<endl;
cout<<"Your input: ";
string line="";
cin>>line;
cout<<"
Please wait while your input is processed and validated..."<<endl;
[code].....
the only thing i havn't tried yet is string streams and i don't necessarly like using them. Am i going to have to go that route? will that even work?
EDIT:I forgot to mention that this is being done on linux and then ported to unix.

I have got an assignment. It is about comparing two files one file has sentences and the other abbreviations. so far i have managed to compare the abbreviations which appear in the sentence and erase punctuation linked to abbreviations.
However I am currently stuck on putting the punctuation back in when outputting the file. I am also stuck with replacing matching words in the sentences with the expanded abbreviations. Not sure which code to show. but sentences and abbreviations are below.
ABBREVIATIONS
Aberd Aberdeen
admin administration
approx approximate
Austral Australia
div division
Capt Captain
Comdr Commander
e east
HQ Head Quarters
m metres
mil million
mt Mount
n north
NATO North Atlantic Treaty Organisation
NSW New South Wales
pop population
s south
sq square
w west
Text file
NATO troops were on exercise in Aberd Capt Jones of the first div told Comdr Frank that his troops were near the E flank of the NATO forces. Complaining about the amount of Admin, Capt Jones radioed the NATO HQ asked for navigation relative to the HQ. The Captain then left.
For example the abbreviation "Aberd" in the sentence above needs to be replaced with Aberdeen from the abbreviations file. I need the last part of the abbreviation not "Aberd Aberdeen" need just "Aberdeen". Hope the info is understandable.

Basically I have to write a program where there is a fund and the user sees a display menu
1- Donate to the fund
2- Invest in the Fund
3- Check Fund Balance
4- Quit
And the user can either donate or invest into the fund and its a loop. I have the loop written and working I just can't seem to figure out how to state how many donations or investments were made before the user selected to quit.
I need a final printstatement to say
The final Funds are $______ and there were __ Donations and ___ investments
How to go about counting the iterations and printing it for the user to see.

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);

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".

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?

COLORREF ref;
ref = m_dcMem.GetPixel(point.x,point.y);
R = GetRValue(ref);
G = GetGValue(ref);
B = GetBValue(ref);
CButton::OnMouseMove(nFlags, point);
}
How can i get the picture contol position even use the scroll bar.
