Visual C++ :: Create Window Form Function Using MFC Or Win32 API?
Jan 7, 2013
My setup is as follows:
There is function written C++, that must be compiled to DLL. This DLL is linked to some CAD (computer aded design) tool, that has special interface for it.
I want to add to this function some GUI (graphical user interface). So the creation of a window is necessary.
I've tried already with Win32, but without success.
The problem is that CreateWindow function requires application instance handle, that is provided by Windows itself when window is created in "normal conditions".

I am wanting to separate the logic from the visual, but I'm having problems when calling the method that controls the actions of the progress bar timer.
Code:
ifndef PROGRESS_BAR
define PROGRESS_BAR
class Progress_bar{
public:
void set_Progress(ToolStripStatusLabel^ label,Timer^ time){
[Code] ....
The way that I'm calling this method on Form1.h
void set_Progress(toolStripStatusLabel1 ,timer1);
Errors:
Error1error C2182: 'set_Progress' : illegal use of type 'void'h:cry_devprogrammingc++school_mediaschool_mediaForm1.h277
Error2error C2078: too many initializersh:cry_devprogrammingc++school_mediaschool_mediaForm1.h277
Error3error C2440: 'initializing' : cannot convert from 'System::Windows::Forms::Timer ^' to 'int'h:cry_devprogrammingc++school_mediaschool_mediaForm1.h277

I have a Win32 C++ application which works pretty well, but I don't like the GUI and I want to replace it with one designed graphically, a la Windows Forms. What is the best strategy to port my code? I tried creating a new Windows Forms C++ application and got pretty far with it, but was stymied when trying to call my unmanaged functions on a button press. If I can't use Forms to add a GUI without completely rewriting the program, what's my best bet?

You place a breakpoint at one of locations within the message loop. But I want the breakpoint to trigger when I click on the application window, for example. But I can't, it went so fast so long as I switch from VS to the application program, the breakpoint is hitted again, then the application is frozen again. I don't know how to setup a conditional breakpoint.

I can tons of information by calling DeviceIoControl (such as device ID, device description, whether it's connected or not) since I couldn't do it all with WMI. But I haven't figured out how to get from DeviceIoControl the info that a call to WMI's Win32_PortConnector gets. Are there any calls, directly to DeviceIoControl or something else that for a given device ID or device description would get the PortConnector information?
I would have used a combination of Win32_PortConnector and DeviceIoControl calls but the trouble with PortConnector is that it doesn't provide any information that would allow one to figure out which device ID it belongs to. Why do I need to do this? Because I'd like to get a combination of all the information the two methods provide for a given device such as a USB port, and all I'm getting from Win32_PortConnector is these scant few fields with no other clue:
string Caption;
string ConnectorPinout;
uint16 ConnectorType[];
string CreationClassName;
string Description;
string ExternalReferenceDesignator;
datetime InstallDate;

I have created a MFC application on Visual c++ 2012. My computer work in Win 7 - 64bits. When I see many tutorial about making the executable file which is independent on .dll library (by changing Configuration Properties ->C/C++->Code Generation->Runtime Library ->Multi Threaded Deburg (MT/d)) the compiler becomes error then I can not get the result as tutorial on internet.
Is there any other way to make the .exe file for this?

I have a form that has been loaded and I click on a quit link to terminate my app but then I display a messageBox to ask the user if they want to save a file before quitting. When the messageBox pops up, another new instance of this form displays. What causes this and how can I prevent it?

My question is are there various ways that I can approach this program. I.e. do I have to use switch statements?
/*
NumToTxt
Creates the appropriate word form of any positive integer up to 999999
*/
#include <iostream>
using namespace std;
//represents the largest array size for the user entered number
const int MAXNUMARRAY = 6;
/*represents the largest number that can be entered + 1. Used to calculate the first number used to truncate the user
entered number and to display an error message to the user that tells the user the largest number that the program will
accept. */
const int BIGGESTNUMBER = 1000000;

An ImageList_Create() function (see here) takes 2 parameters: cx and cy which are the width and height of each image.
Everything is good if I know in advance what size my images will have. But what if I don't?
Let's say I select 32x32 and my images are sized as 16x16. What will happen with the image list? Or my images are 48x48 and the image list should grow to accomodate the extra space. Since on Windows image list is just one big bitmap, will the height of the image list shrink/grow to 16/48 or not? Is there a way to test such behavior?
The problem I'm having is to check whether the actual images will be truncated when they are bigger that the image list initial size or not or whether I will see some extra space if the images are smaller.
The closest way I see is this function, but I am not sure its the right one to apply to the image list itself and not to the image inside the list.
How to test this properly and reliably on Windows XP+?

I want program to make bitmap from my Window. I also want to do add some additional steps which I will try to add later. But now I want to ask you how to fix the code. For some reason when I debug the code (break on line 73 of capture.cpp) there the pointer pBitmap is 0x00000000 . So how to correct the code to successfully capture Window? Here I give the complete codes:
stdafx.h
Code:
#pragma once
#include "targetver.h"
#include <stdio.h>
[Code].....
Feel free to set correct name of Window on line 17 for FindWindow() function.
PS: The code is remake of script to capture screen, which saved the bitmap to file. This is not what I want because I would be content if I could send (or maybe share!) the bitmap to ahk script which will ask my C++ program for the bitmap.

I have a CFormView derived window which I would like to position at run time. In particular when the user clicks a button I would like to shfit the CFormView window and open up a new Dialog window so that the two do not overlap.
I have created the CFormView window and the dialog window - how to shfit the CFormView window?
I shift the Dialog window as follows in OnInitDialog: SetWindowPos(NULL, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOZORDER);
