how to change the mouse tracking icon during runtime. I wish to emulate the Microsoft Paint app behavior with respect, for example, to click on a toolbar button such as the 'Fill With Color' bucket and have the mouse pointer icon change to a little bucket. I wish to do this in an MFC SDI app.
Here's a bit of code that does nothing that I can tell, although it compiles and runs. (m_hIcon2 is a member HANDLE, IDI_FLOODFILL is an existing icon in the app resources). I have come across numerous other examples that do not work and/or will not compile using VS 2010 Win7(64).
I have QTextEdit in mainWindow. I'm trying to resize QTextEdit so height = mainwindow.height and width = height/2. That should change when I change the size of mainWindow during runtime. How can I do that?
How I can make 2D games in OpenGL. I have sprites, but when I load them in game, they're all big and stuff, not pixel for pixel how I'd like them. How can I do this?
My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code: #include<iostream> #include<algorithm> #include<vector> using namespace std; void change(double cents, int a[]); int main() { double Dollars; double cents;
class Base { ..... ..... ..... virtual void display();
[code]....
in the above polymorphism why is it called runtime polymorphism when i can say seeing the code itself that display() function in derived gets executed with ptr->display(),so how does it become runtime polymorphism when i could get decide at compile itself ???
While running a Doc/View SDI, is there any way to switch from text mode to rtf mode during runtime? Search reveals nothing.
Say I have an editor and I want the app to use text, I can set the ctor as follows.
Code:
CEditorDoc::CEditorDoc() { // TODO: add one-time construction code here m_bRTF = FALSE; }
But once I've done that and compiled the app, while it's running, is there a way for the user (or programmer) to change the mode back to RTF? One solution that occurred to me is to use 2 document classes, but that's a hassle.
I am developing a small game using MFC in which the game options like new game, save, open, exit etc. can be selected from the menu as well as from the buttons inside the window. I have no problems with the menu but the buttons do not seem to work at all.
The buttons are created at runtime using CButton class. To associate the buttons with the corresponding functions, I just used the same resource ID for the buttons as the menu options, but that did not work. When I click on the buttons, nothing happens. If I assign different resource IDs to the buttons, how do I handle the message map entries? Do I have to write different message map entries for the menus and the buttons while their function is exactly the same?
I downloaded Oracle instantclient-basic-nt-12.1.0.1.0.zip and instantclient-sdk-nt-12.1.0.1.0.zip and extracted both to c:oracle I then went into visual studio 2013 and created a Win32 Console application with all default parms.
I then went into project -> properties -> C/C++ -> General -> Additional Include Directories and added my include path C:oraclesdkinclude
I then went into project -> properties -> Linker -> General -> Additional Library Directories and added C:oraclesdklibmsvcvc11
I then went into project -> properties -> Linker -> Input -> Additional Dependancies and added oraocci12.lib
The program compiles but when I debug i get a RUNTIME error that says "The program can't start because oraocci12.dll is missing from your computer. Try reinstalling the program to fix this problem. But I know the file exists in C:oraclesdklibmsvcvc11oraocci12.lib
This is the code if it makes a difference
Code: #include "stdafx.h" #include <iostream> #include <occi.h> using namespace std; int _tmain(int argc, _TCHAR* argv[])
I've come to a point where I want to manipulate an image file at run time or with pre-determine sizes and have to be applied when the windows is moved or through in program options.
I know I can do the applying part. However I am a little unsure of how to tackle the image manipulation. I want to make it so that it is not os dependant. So I know I can not rely on any os functions. The only other thought that came to mind was to deal with the video card itself.
So the main question after all of that is said and done. How is c++ able to interact with the video card directly for images? Or if there are existing function I can use. How do they do that? If I can use existing function I would like to be able to manipulate it myself.
I have this TicTacToe program that needs finishing. All the code is finished, but I'm getting runtime errors. It is printing out junk values from my array when they should be empty.
//Player.h #include <string> #include "TTT.h" using namespace std; class Player {
I am getting a strange runtime error when trying to run my hash table program. I have it separated in 3 separate files. I believe I have narrowed down where the error is occurring. It is either happening in insert(const &string s) or in the implementation of vector<list<string>> ht. I would appreciate some input. This is the implementation of insert():
void HTable::insert(const string &s) { int h = hash(s); cout<<h<<endl; list<string> &tempList = ht[h];
[Code] .....
And it is giving me some sort of compilation error saying I cannot convert a type string to type list.
I'm doing a project. And I want to give the user the ability to write methods just like you would regularly in c# during runtime and then use them during runtime. Is such thing even possible? If so how?!
I tried in internet but am unable to know the differences. I want to know the difference between those two in terms of run time and compile time. Explanation required also for below one. Is this run time or compile time? How does we actually decide which is run time and which is compile time!
