I have implemented a copy control version of binary tree.. As I am a Beginner. I think i have made my mistake.
Code:
#include <iostream>
#include <string>
class TreeNode{
TreeNode(const std::string &val):value(val),count(new int(1)){}
TreeNode(const TreeNode& rhs):value(rhs.value),count(count),left(rhs.left),right(rhs.right){++*count; }
[Code] ......
I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.
How do I bind a DATE column in a DataGridView Control to a DatePicker control (using C#)? I already have the DataGridView control bound to a database stored procedure which takes a DATE value as a parameter and selects joining table based on the results.

I am writing a program to hide files behind other files using Alternate Data Streams in Windows NTFS file systems.

I am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.

When including a header file in stdafx.h, should that file still be included in the source file where it is actually used?

i've taken a couple courses in C Programming and all of the assignments were pretty basic. I've been looking into some of the awesome things that people have been doing with the Raspberry Pi and noticed that some of them are using the C language to control robotic arms and LEDs. I skim the code for some of these projects and notice they are using header files and code that i have never seen, nor are they in the books that i have. for example:
#include <fcntl.h>
#include <sys/mman.h>

is there a way to tell WPF that I'm going to do a lengthy update on a control (TextBlock), and that it shouldn't redraw it until I tell it I'm done? I'm adding a large number of items to the Inlines property, and it has to redraw the entire control every time I add an item, which takes a very long time - about 1 second for every 100 items. I know some other frameworks allow freezing of certain controls, but I haven't been able to find anything in the documentation or on google. I've tried collapsing the TextBlock, and then making it visible again after the update, but it did not improve the performance at all.

I am running some simulation, in which i need to control the iterator of a multimap, like
multimap<double, int> mapp;

int n=6;
for(int i=0; i<5; i++) {

However this way of controlling is not possible for multimap. Why and how the make it work? Do I need to overload the operator +?
is there any way to have the program control go some two paths at once? For example: if my program has two functions, one that does some simple calculation that requires nothing from outside it to set the variables and another that displays text for the user to read then enter something. Is there any way to have both run at the same time?
simpleFnc()
{int a = 1;
int b = 2 ;
int c = a+b ;
[code]....
There is no connection of simplefnc to anywhere else in the program so is there any way to get it to run at the same time the other function is running?

I am having trouble understanding what I need to do to halt the flow of a program until a video file finishes playing. So far I have accomplished getting the video to play, but the program continues while the video is playing rendering the content of the program on top of the video making it not seen.
My goal is to make the video play, then once it has finished the rest of the program should run.
So far I have this in the start up area of my code:
//Initialize components for DirectShow to stream a video at start-up
CoInitialize(NULL);
//creates filter graph manager
[Code].....
After this code runs once, the program proceeds immediately into the loop where my update and render functions for the program runs. Preferably, I want to stop just the render function while allowing the update to continue to check if the user presses a key to skip the video. What do I need to add to the code to do this?

Ive set up one form that has two labels at the top (Western, Eastern). Below that I have a tabcontrol that contains two tabs (Sales, Products)
I have added four user controls:
WesternSales
WesternProducts
EasternSales
EasternProducts
The idea is that when you click on one of the labels (Western or Eastern) you access the tabs relevant to that region.
So, If i click on the "Western" label and then the "Sales" tab, the program loads the WesternSales usercontrol into the Sales tab. Likewise, if I click on the Eastern label and then the Sales Tab, the program loads the EasternSales usercontrol into the Sales tab, etc.
I want to eliminate the need for multiple data adapters. How can I load data from our database into each of the respective usercontrols using one data adapter?
