In the main window I draw lots of background stuff using a memoryDC and BitBlt(). In the child window, I actually am not drawing anything, I just created it to have events like mouse over, etc. In the child window when the mouse is over the window I bring up a pop-up window. This works unless my mouse is over any parts where something is drawn in the main window, then the popup just flickers constantly. Why is the main window affecting my mouse over events if I am not handling any such events for it?
I have looked on this website and stumbled across this link: [URL] .....
My question is can how do I use that code when im console programming?
When I try this code I get errors.
" line |14|error: initializer expression list treated as compound expression|" " line |17|error: a function-definition is not allowed here before '{' token|" "line |40|error: expected '}' at end of input|"
Code: #include <iostream> using namespace std; int main() { int MouseMove(100,100); void MouseMove (int x, int y ) {
How do I detect left mouse button down and up events on the 'Close' option of the system menu that appears when the mouse is clicked on the top left corner of a form?
For a ribbon bar with edit controls (CMFCRibbonEdit) I want to handle the mouse scroll events for the edit controls. That is, when the user clicks and then scrolls on the edit it will navigate a predefined list of strings. I want to capture the scroll event in order to update the edit text step by step.
This kind of behavior is implemented by the Spin Edit; I don't want to use the spin edit control since it only uses a list of integers and the spin buttons are too small.
Is there a way to catch the mouse scroll event for the CMFCRibbonEdit control? How to approach message handling for the ribbon (other messages than the COMMAND allowed by the ribbon designer). I'm using VS2010 on Windows 7 and the ribbon was designed with the ribbon designer?
The problem is that I want to scale the output. I was trying to send message to my control before blitting:
SendMessage( EM_SETZOOM, numer, denom ).
It scaled the control itself, but the blitted context was still the same size as original content CRichEditCtrl (befeoe scaling). Is there any way to blit/render scaled content of CRichEditCtrl to any device context (screen/paper) ?
My app crashes when I attempt to create a CWnd as shown below. I am attempting to create the CWnd with a a parent of type CFormView. Why this might be crashing?
Code: mfc100ud.dll!AfxGetInstanceHandle() Line 21 + 0x20 bytesC++ mfc100ud.dll!AfxRegisterWndClass(unsigned int nClassStyle, HICON__ * hCursor, HBRUSH__ * hbrBackground, HICON__ * hIcon) Line 1462 + 0x5 bytesC++
And the line that crashes here us the AfxGetInstanceHandle() call:
Code: LPCTSTR AFXAPI AfxRegisterWndClass(UINT nClassStyle, HCURSOR hCursor, HBRUSH hbrBackground, HICON hIcon) { // Returns a temporary string name for the class // Save in a CString if you want to use it for a long time LPTSTR lpszName = AfxGetThreadState()->m_szTempClassName;
// generate a synthetic name for this class HINSTANCE hInst = AfxGetInstanceHandle();
I am writing a program which is using SDL library. I have two different classes which one of them is Timer Class and the other is EventHandling Class.
I need to use some member functions and variables of Timer in some Eventhandling Class member functions, Although I want to define an object of Timer in int main {} and relate it to its member function that has been used in Eventhandling member function in order that it becomes easier to handle it, I mean that I want to have for example two objects of timer and two objects of Eventhandling class for two different users.
I do not know how to relate an object of a class from int main{} to its member function which is being used in another class member function.
When I click the mouse, the program doesn't seem to record the coordinates. So the if statements are never executed. One thing I noticed was that when the do while loop is running and the left mouse button is not pressed then X and Y of dwMousePosition are both 0. But then if I press the left mouse button then the coordinates become x = 1 and y = 0.
I am on Windows 7, 64 bit, using Visual Studio Express 2013 for Windows Desktop
I have a dialog app with two separate static controls. Both controls have been subclassed from CStatic derived class to implement drag and drop and double clicking. The class works just fine, but I cannot figure out which of the controls is being double clicked or dragged and dropped onto because I only have the code below operating. I need some method in the derived class to determine which control is being manipulated.
Code: // header file #pragma once #ifndef __AFXWIN_H__
I am currently starting to attempt to make a program that can move my cursor to certain colors on my monitor. The problem is this seems like it will be 10x harder than I first thought.
I have a dialog control where I am using a slider control. I have handled the notification messages sent by the slider control. When user clicks on the slider, the slider moves in steps. I want to bring the slider directly to the position where user has clicked the mouse. The slider thumb should directly move to the clicked position instead of in steps.
I am writing a program to map keyboard and mouse to an xbox 360 controller with win32 and xinput. I have everything going fine but when im trying to control the mouse with the thumbsticks I get problems with the movement if my program has the focus it moves fine but when I put another window in focus the movement is over sensitive here is the code I am using
Nothing complicated, and it works well ... except one thing: when I press the shift key and the mouse is moving by SetCursorPos, is moving pretty slow ... why ? I can not figure out why ! For testing, I attached the test project ...
We are coding a Blackjack/21 game. I have a Deck.cpp class, Deck.h, Play.cpp (holds Main), and Card.h (holds card struct). I also have a Hand class/header, but I'm not using it yet. This is what is required per instructor.I am having issues accessing the functions that are in my Deck class. I have tried a few other means to access the class's function, but I've already gotten rid of those. These three are my latest attempts with the specific errors in the comment on the line the error was happening. ve.
Here is my Deck.h
#pragma once #include <iostream> #include <fstream> #include <string> #include <cstdlib> #include <ctime> #include <iomanip> #include "Card.h" #include "Hand.h" using namespace std; class Deck
I am writing a program where all work is done in the class methods. Main is used to call the methods. I need to know how to get a loop to work without any variables in main that can be used outside the methods. This is what I have in main:
#include <iostream> #include <string> using namespace std; #include "FerryBoat.h" int main() { //create a constructor for a ferry boat FerryBoat myBoat('B', 20, 'A');
I'm trying to pass the value of an object created from a class file to a function outside of the "Int Main" function in the main.cpp file. I've successfully created the object, I just want to pass it to a void function but I'm getting the scope error below. I'm not sure how to correct. I'm not having much luck with research either (static variables?).
I know if i will not use the pointer base class function "virtual double grossPay" will be called for both base class object and derived class object and when i will use pointer with reference to the object because base class function is virtual it will look for same function in derived class and if available it will execute it.
I am a beginner with C++, taking a class right now. The lab this week is to create a user defined class and have it accesses in a separate .h header file from the main.
I think I'm finding my way through it, but I'm getting a complie error that makes no sense to me:
I know how to define a shape (here, a rectangle) and attach it to a window in C++ as follows:
Code: #include <Simple_window.h> void cir() { Circle c(Point(100,100),50); } int main() { Simple_window win(Point(100,100),600,400, "test");
[Code] ....
But how to define a shape (say a circle by that cir() function which is) outside of the main() function that is how to create a circle inside of the cir() function and it returns that circle when I called it in my main() function so that I can attach it on the window win to be visible?
I have been playing around with property sheets/property pages and have been successful in getting them to work in a secondary dialog by calling the property sheet using DoModal().
How to get the property sheet to display on the main dialog of a dialog application.
I am using VS2008 and CMFCPropertySheet and CMFCPropertyPage.
Is it possible to use a CFormView as the main view without using document support. IE pointing CWinApps m_pMainWnd to the CFrameWnd derived MainFrame and attaching the CFormView from there. It does not seem to be working and I was wondering before I waste any more time on the solution if it is even possible. I know it is an easy solution if I create a true SDI application however I have no use for documents in this application.
