Visual C++ :: FLTK - Creating A Box With Rounded Corners
May 8, 2014
Draw a box with rounded corners. Define a class Box, consisting of four lines and four arcs. So I wrote the below code for that exercise:
Code:
#include <Simple_window.h>
Simple_window win(Point(100,100), 600,400, "semi-ellipse");
struct Box: Shape{
Box(Point p, int ww, int hh): w(ww), h(hh)
{ add(Point(p.x-ww,p.y-hh)); }
[Code] .....
When I ran it I faced this exception:
Unhandled exception at 0x757FE9D7 (ole32.dll) in test.exe: 0xC0000005: Access violation reading location 0x00000004.
I know this refers to declaring "Simple_window win(Point(100,100), 600,400, "semi-ellipse");" in global state. But I did that because I had to do it. The problem is that how to attach lines and also object (here b) to Simple_window win in either parts (main() function and also Box struct).

I installed FLTK 1.3.X from [URL] on my visual studio 2012 compiler and use PPP book for C++ programming [URL]. My problem is about filling a Shape in.
Code:
#include <Simple_window.h>
using namespace Graph_lib;
int main() {
Simple_window win(Point(100,100), 1000, 600, "Binary_tree");
Graph_lib::Circle c(Point(200,200),50);
c.set_color(Color::red);
[code]....
When I run the program, All three Shapes are drawn on window but only the Rectangle is filled in! Why? set_color works for the three and apparently the set_fill_color is defined for all Shapes and it too should work but why it doesn't for Circle and Ellipse?
This [URL] is the .CPP and .h files ( )

I wanna create a DLL from my C++ program. My output of my C++ program is a text file called Centre_Cartouche.txt My output is two text files called brd.txt and sym.txt
At the beginning my program was just a main which contains all development (Main.cpp). Now I created function (in _Cartouche.h and _Cartouche.cpp).
My debugger tell me that the simulation works. But my file Centre_Cartouche.txt is not create.
_Cartouche.cpp_Cartou.hbrd.txtsym.txt

How to create/use a graphical interface. Especially since Microsoft has removed Windows Form Application support from Visual Studio 2012 and 2013.
I know that Windows Form Application is still supported with C#, but C# is definitely not an option as the program I am developing is heavily depended on some of C++'s more advanced features not present in C#.
Is there an alternative to Windows Form Application? I would definitely prefer one, as I doubt that some workarounds would work for long. What are common ways to create a GUI application in C++? There certainly must be some ways. In Java one would use something like JFrame.
Crossplattformcompatibility: The program I am creating is a Microsoft Windows program only. So I don't care if it runs on Linux or Mac. It only has to run from Windows 7 onward. So if there are more than one standard ways to create a GUI, I would prefer the one working best for Windows.
By the way, I am using Visual Studio 2013.

I'm turning mad with a little problem with Visual Studio 2008 and MFC. I'm working on a project actually and I'm trying to create an SDI Application. Right, now I want to add a dockable DialogBar. Well, the first time I added it with the resource view, I can create the bar without problems. But... I want to add some controls like a couple of ListBox, buttons and so on. The program doesn't allows me to create member variables for these controls. The option appears in grey.
Searching a little, I found that it's mandatory to create a new class derived from CDialogBar and "enhance" it with the Message handler and so on. I've been reading some tutorials and it didn't work for me.

Is it possible to create a virtual mini server (like IIS) that takes http request? I have a toolbar that queries an DLL using http request, and then that DLL stores some arguments in some XML file, which is read by an anti-malware.
Now every customer can't have an IIS server installed. Most of the end users uses Windows XP home edition. So is there a way i can create a virtual mini server that can be used in these PCs for placing http request?

I am trying to simulate the logical circuits having NAND gates. I am reading the structure from .bench file. The structure of a circuit looks like below:
Code:
INPUT(1)
INPUT(2)
INPUT(3)
INPUT(6)
INPUT(7)
10 = NAND(1, 3)
11 = NAND(3, 6)
16 = NAND(2, 11)
19 = NAND(11, 7)
22 = NAND(10, 16)
23 = NAND(16, 19)
It can be seen that the inputs for Gate 22 are 10 and 16 which are also NAND gates. On the other hand, for gate 10, the inputs are 1 and 3 which are simple inputs. So, i need to sort the gates topologically. Although topological sort will not affect the output for this particular example but i have big circuits also in which topological sort is required. But we can use this simple example to do the topological sort.
My effort:I thought to create a map which will keep the information about the gate name and its indegree. But i am unable to proceed further.
Code:
void Circuit::topologicalSort()//topological sorting (for the mixed circuits) {
int counter = 0;
std::map<string, int> unsortTopoList; //this list keeps a track of gate name and its Indegree
for(int i=0; i<gates.size(); i++) {

I have a problem creating a MAPI property. I have code like this:
Code:
intSetProperty( LPPROFSECT lpProfileSection, LPSPropValue lpPropValue) {
HRESULT hr;
LPPROPDATA lpPropData;
SPropValue spvEID;
[Code] .....
I want to create the choose_directory_Automatically property if its not exists. But I don't know how. If the CreateIProp method returns me a pointer in lpPropData how can I put the PropTag and the Value in it?
I have already implemented change the property if it exists already but the Outlook Addressbook stays on automatically until I or the user creates this property. I took a look with OutlookSpy at this property but I could not come any further.

This is the problem in detail:
I have a VC++ project to create a DLL that will be used as a Plug-in in an external programm. This DLL uses some MFC functions. The initial configuration of the project was:
-Use of MFC: Use MFC in a Static Library
-Common Language Runtime support: No Common Language Runtime support
-Runtime Library: Multi-threaded Debug (/MTd)
This configuration worked fine, there were no compilation errors and the resulting DLL worked correctly.
The problem came when it was necessary to add to the DLL some functions of .NET, using the namespace System and similar. To do that, I had to change the Common Language Runtime support, to Common Language Runtime Support (/clr). Then, when I tried to compile, I got this message:
'/MTd' and '/clr' command-line options are incompatible
So I changed the Runtime Library to Multi-threaded Debug DLL (/MDd). Then I got this error message:
Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version
So I also changed the Use of MFC to Use MFC in a Shared DLL.
After this, the compilation was correct. Then logically the size of the generated DLL is smaller, but this new DLL does not work correctly, the external program in which this DLL is used crashes.
I don't know what to do to fix the problem. Maybe I need to add some other DLLs or files to the directory where the DLL is located, where the external program uses it. But I would prefer to include a single DLL file, but this seems to be incompatible with the use of .NET functionality.

I need to create an object of a mfc derived CFormView class that's not in the doc/template (a second view class). But it was generated with a protected ctor. Here's the code explanation with comments.
I'm thinking all the normal classes of the Doc/View template are created starting with this code, but within the template code base.
Code:
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(IDR_MAINFRAME,
RUNTIME_CLASS(CViewSwitchDoc), //<-expands to-> ((CRuntimeClass*)(&CViewSwitchDoc::classCViewSwitchDoc)),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CViewSwitchView));
But I have generated "another view" using the "Add Class" Wizard, it's a derived class of mfc CFormView which I named ViewForm. However I'm having a problem creating an instance of it because of the generated protected ctor and pulls a compile error of not being able to access ctor. Below are the header and implementation files of this said ViewForm class. How to create an object of this view ? Did I go about it all the wrong way since it's not in the doc/template group ?
// ViewForm.h file
#pragma once
// ViewForm form view
class ViewForm : public CFormView {
DECLARE_DYNCREATE(ViewForm)

I am looking for direction on what topic I should be reading up on. I am new to C++ and Windows MFC.
This is my real world problem, in the context of the application user. (these term do not refer to OPP concepts)
I want to create shapes (containers) in an application that will respond and collect other objects;
Imagine a Windows frame, containing several 2 dimensional squares. I want to be able to drag and drop marbles into the squares,and have the square retain and display the marbles in the square, in the order that they were dropped in.
How do I create the shapes, and how will the square sense when a marble is over it?
How would I create irregular shapes (a combination of lines and curves) that would be responsive to the marbles?

I'm am having a few issues with this program, they stem from passing the color.h and .cpp into another .h and .cpp, and frankly getting how those two things really fit together.
For this problem, you will design and implement 2 classes and then write a driver function to test these classes. The first will be a C++ class for an abstract data type color with a public enumeration type colorType that has the color values shown in Listing 10.8. Your abstract data type should have an attribute for storing a single value of type colortype and member functions for reading (readColor) and writing (writeColor) a color value as well as setting and accessing it. The function readColor should read a color as a string and store the corresponding color value in the value attribute of a type color object. The function writeColor should display as a string the value stored in the value attribute of a type color object (see Figure 7.5). Modify class circle and the driver function in Listing 10.9 to include and use this class. You'll need to remove the declaration for color in class circle. Test your modified driver function with the new color and circle classes.
The second class will be to design and implement a rectangle class similar to class circle. Be sure to incorporate the new color class you have written and tested in the first part of the programming exercise. Write a client program that asks the user to enter a shape name (circle or rectangle) and then asks the user for the necessary data for an object of that class. The program should create the object and display all its attributes.
The circle class .h and .cpp files as well as the original driver function will be supplied. You are to provide the .h and .cpp files for the new color class and the modified driver function as well as the .h and .cpp files for the rectangle class and the client program that uses all three classes.
color.h
Code:
//color.h
//Color class definition
#include "stdafx.h"
#ifndef COLOR_H

This program is incomplete as I am having difficulty creating the function that needs to find the number of perfect scores entered by the user. I have everything but the function complete ,here is my code:
Code:
// Write a modular program that accepts at least 10 integer test scores from the user and stores them in an array.
// The main should display how many perfect scores were entered (i.e., scores of 100), using a value-returning countPerfect function.
// Input validation: Do not accept scores less than 0 or greater than 100.
#include <iostream>
using namespace std;
int countPerfect(int intArray[], int); // Function prototype

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:
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), CString(windowName.c_str()), WS_VISIBLE | WS_BORDER, dimensions, parent, NULL, NULL);
The call stack looks like this:
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 trying to create a loop to call in the entries from the text file named Set. The entries of Set.txtare :
1 2 3
2 4 5
and so on .. (64 such combinations)[/CODE]
It basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set
My test files are located in D://data// and are named tst_data1 to tst_data64.
I created a loop for test set but its incorrect
Code:
// loop for test samples
char basefilename[] = "D://data//";
char , testFilen[160], numiChar[10];
for (int i=1; i<=64; i++) {
strcpy(basefilenme, "D://data//");
strcat(testfilename, Set[]);
[Code] .....
How can i call the Set .txt and how to define it.

I'm using CStatic inherited class in my code and creating static text boxes dynamically. Now for assigning unique control ID I'm creating a static control from resource editor and destroying it before calling CStatic::Create() and using its control ID say ID_STATIC_SAMPLE.
If I do not use this parameter of Create(), the static control is also being created, so what is the use of this unique ID. And any other better way to assign a ID for dynamically created static controls.
