Visual C++ :: How To Capture Mouse Scroll For CMFCRibbonEdit Class
Oct 18, 2014
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?

I have a main CWnd class called CMainWnd which is created like this:
Code:
DWORD dwStyle = WS_VISIBLE | WS_BORDER | WS_CLIPCHILDREN ;
...
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), L"", dwStyle, rect, parent, NULL, NULL);
And I draw smaller windows on this main window with a CWnd-dervied class called CClientWnd, which is created like this:
Code:
DWORD dwStyle = WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | WS_BORDER;
...
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), L"", dwStyle, rect, parent, NULL, NULL);
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 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 an emulation project I've been working for a long time (the Altair32 Altair/IMSAI emulator) and I'm trying to simulate a dot-matrix printer for list output in CP/M.
Here's what I have so far and where I'm stuck and need a push in the right direction. I'm using a dialog box with a green bar paper bitmap as the client area background. I used CreateFont to load a dot matrix printer TrueType font and have the base code to print on subsequent lines. So, based on the dialog size, font size, etc., I get about 10 lines of dot matrix printing, 80-characters wide. So far so good.
The problem arises in how do I scroll the text like on a printer? I thought about trying a static text control or an edit box, but the text to be printed is of an unknown size and ISTR that both of those controls have finite size limits (32k but maybe I'm wrong). They would also need to be transparent so that the green bar paper shows through.

I was loaded a bitmap using this code. I'm using mousemove method to known the Dialog's mouse move position & get the RGB pixel.
I want to get the picture contol's mouse move position & using this point (x,y) i will get the particular color ref value R, G, & B.
My picture control size is 256 * 256 & I was loaded an image 512 * 512.
Using scroll bar, I was view the image but can't get the particular pixel in the picture control.
The below code get the Dialog's mouse move cursor position & RGB Values only.
Code:
void CMyDlg::OnMouseMove(UINT nFlags, CPoint point) {
int R,G,B;
COLORREF ref;
ref = m_dcMem.GetPixel(point.x,point.y);
R = GetRValue(ref);
G = GetGValue(ref);
B = GetBValue(ref);
CButton::OnMouseMove(nFlags, point);
}
How can i get the picture contol position even use the scroll bar.

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
Code:
#include <iostream>
#include <windows.h>
#include <string>
#include <new>
#include <stdio.h>
using namespace std;
INPUT_RECORD ir[128];
[Code] ....

I have the following problem:
My mainframe-window in a MDI-app has a CDialogbar.
Every time the mouse moves over a control in this dialogbar the status bar is updated by a text.
The app craps the text from the resource strings that has the same ID than the dialogbar-control, randomly.
I do not want this. How can I avoid this?

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__
[Code]....

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
Code:
if(_controllerState.Gamepad.sThumbRX >= XINPUT_GAMEPAD_RIGHT_THUMB_DEADZONE) {
GetCursorPos(&mousepos);
profile->Buttons[6]->input.type = INPUT_MOUSE;
[Code] .....
I have tried everything to fix it.

In a SDI app, I constraint the mouse to move only an horizontal direction, if "Shift" key is pressed ... here is the code:
Code:
void CTestMouseView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) {
// TODO: Add your message handler code here and/or call default
if(GetKeyState(VK_SHIFT) < 0) {
CRect rect;
GetWindowRect(&rect);
GetCursorPos(&m_point);
[Code] ....
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 ...

I am writing a small editor for RSL coding, and ive got an external program "3Delight" to compile the code.
Now i want the output from that exe to be captured in a string once the compilation is comlete, but all of the methods ive found online dont seem to work for me. Ive tried using _popen which works if i run a normal command like "dir", but not with the exe.
This is the function ive been using that works with the normal commands
std::string exec(const char* cmd) {
FILE* pipe = _popen(cmd, "r");
if (!pipe) return "ERROR";
char buffer[128];
std::string result = "";
[Code] .....
and this is how i was calling it, but it just returned an empty string, even though the exe printed "Compilation successful"
exec("""%DELIGHT%/bin/shaderdl" "E:/RenderManShaders/TestArea/Source/basicDiffuse.sl"")
