Visual C++ :: Splitting Child Window In MFC MDI Program?

Dec 4, 2012

how to split a child window in an MFC MDI program.

Splitting Child Window in MFC MDI Program

[URL]

For my purposes, this achievement is practically useless because I cannot find a way to pass text from one CRichEditView window to another.

Given two CRichEditView windows, CInputViewView and COutputView as child windows in an MFC MDI app, my goal is to capture text in the former and print that text in the later using a button click.

Using what appeared to me to be a logical way to proceed, I tried variations of the following code:

Code:
void CMainFrame::DoSomething() {
//MessageBox(_T("Like What ?"), _T("Do Something"));
//CInputViewView * pin = (CInputViewView*) GetActiveView();
CInputViewView * pin = (CInputViewView*)m_wndSplitter.GetPane(0,0);
pin->GetWindowTextW(m_csDisplay);

[Code] ....

None of this works and even the attempt to access the pane results in an app crash in winsplit.cpp.

Code:
#ifdef _DEBUG
void CSplitterWnd::AssertValid() const {
CWnd::AssertValid();
>ASSERT(m_nMaxRows >= 1);
//..

Visual C++ :: Child Window On Top Of Control

Visual C++ :: MFC MDI Tabbed Child Window Positioning

Jul 18, 2013

Is it possible to specify the size/position of tabs in an MFC MDI tabbed application?

I am trying to save the open tabs when exiting the program and restoring them when the application is relaunched. I have come up with a method of saving and reloading the tabs, but I cannot restore their position.

I have seen SaveMDIState and LoadMDIState but I can't make it do anything and I'm also not sure if it's what I need.

C :: Creating Simple Calculator By Splitting The Program In 3 Files

Feb 21, 2014

I am new to C programming, I have been given an assignment to create a simple calculator by splitting the program in 3 files. It should have 2 .c files and 1 .h... I went through the internet extensively and could only come up with this.

main.c:

Code:

//Calculator main.c
#include <stdio.h>
#include <conio.h>
#include "Functions.h"
int main() {
float x = 0, y = 0;
int operation;

[Code]...

Functions.c

Code:

#include "Functions.h"
extern float x, y;
float addition (float a, float b) {
return a + b;

[Code]...

Functions.h

Code:

#ifndef FUNCTIONS_H_INCLUDED
#define FUNCTIONS_H_INCLUDED
float Sum(float a, float b);
float difference (float a, float b);
float remainder (float a, float b);
float product (float a, float b);
#endif

When I do a 'cl main.c' on the Developer Command window for VS2013, i get an error that reads :

main.obj
main.obj : error LNK2019: unresolved external symbol _difference referenced in function _main
main.obj : error LNK2019: unresolved external symbol _product referenced in function _main
main.obj : error LNK2019: unresolved external symbol _addition referenced in function _main
main.exe : fatal error LNK1120: 3 unresolved externals

Visual C++ :: How To Create MDI Child With Borders

Jan 7, 2013

How can I create MS Word 'print layout' like interface. The attached picture says it all. Basically I want a shaded area around my document just like word so it gives a feel of the 'page'.

I was hoping I can override some function somewhere and along that lines tried playing around with below but that didn't work.

Code:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) {
if( !CFrameWndEx::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = 250; // just playing around with size
cs.cy = 250;
return TRUE;
}

How can I do that?

Visual C++ :: Passing DDX Control Variables Between Dialogs (Parent->Child)

Jul 19, 2013

I have a main dialog which has (DDX?) controls for the user. eg a slider, and a combo box.

Previously, an image adjusted by these controls was in the same dialog.

I need to put this image in a New, separate dialog but it still must be controlled by the slider and combo box on the main dialog.

My question is how can I pass the control's variables between the dialogs? I have, say,

Code:
//MainDlg.cpp
DDX_Control(pDX, IDC_ComboBrightness, m_Brightness
I was told that I could do something like:

Code:
//ImageDlg.h
public:
ImageDlg(CWnd* pParent = NULL, CComboBox m_Brightness); // standard constructor

But I get errors including: Missing default parameter for parameter 2

I also need to pass the image array, is that perhaps the same method?

Visual C++ :: CEdit Control As A Child In A CListCtrl For Making Each Column Editable

Jul 8, 2013

I am using a CEdit control as a child in a CListCtrl for purpose of making each column editable. The application is a dialog based app. My problem is... I have overwritten OnOK and OnCancel in the main dialog so the edit control never receives notifications for Escape or Enter whether in OnChar or PreTranslateMessage and I would like to delete the CEdit control after updating the CListCtrl on Enter. What can I do? I have rewritten this code many many times over the past 4 days and nothing is working.

Visual C++ :: Capture Of Window?

May 5, 2014

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.

Visual C++ :: MDI Application Client Window

Apr 17, 2015

I am developing a MDI application that will contain a RibbonBar and a Properties Pane window. The MDI documents are not tabbed. I am finding that when I try to move the client window around, it gets clipped by the RibbonBar and the Properties Pane window (shown in image). I know the client window cannot go outside the client area, but can the client window be on top of the ribbon bar and the properties pane window?

I am using VStudio 2008.

Visual C++ :: How To Prevent A Window From Being Moved Or Resized

May 20, 2014

I know I can set the window properties on creation, but I'm trying to figure out how to prevent a window from being able to be moved or resized. I've been looking online and it looks like it involves overriding the WM_SIZE, WM_SIZING, or perhaps the WM_WINDOWPOSCHANGED message handlers. I want to be able to have a menu option that "locks" the window position, and of course allows normal window behavior when the option isn't checked.

Visual C++ :: How To Call Dialog Window (formed As Resource) From DLL

Jan 19, 2013

Is there some document, that describe the sequence of actions, that result in displaying of a Dialog Window from a .DLL.

One important detail - the Dialog Window is created via resource/toolbox inteface.

Below is code from some example (which works), that displays simple window (with client area inside it).

In this code the window class is ctreated inside of application class.

Here is extract from application class:

Code:
class CMyWindow : public CFrameWnd {
CStatic* cs;
public:
CMyWindow();
};
CMyWindow::CMyWindow() {
Create(NULL, L"MyWindow", WS_VISIBLE, CRect(0,0,200,200));

[code].....

Where is my mistake ?

Visual C++ :: Disable Controls And Change Window Size

Jun 6, 2013

I have created an exam environment for our schools, it comprises of 3 files; a .kix file that says if they are in the examination group run a .vbs file. The .vbs file kills the explorer.exe task so they don't have any taskbar or desktop shortcuts and then opens a .hta file.

The .hta file is a user interface that has icons for apps like Win Word that executes the application when you click on it. There is also a log off button.

Looking for some code that stops the students from being able to close, minimise and resize the window. Looking for code that can lock this down so they literally can't do anything except click the icons inside the window.

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".

C++ ::  make Program That Can Type String Into Another Window?

Apr 26, 2013

I am trying to make a program that can type a string into another window. I have gotten it to the point that it can type the string, just not correctly. It will type random numbers and not the given string. The key event uses ASCII code for the arguments, and I don't see anything wrong with my numbers. Here is the code I have so far.

#include "stdafx.h"
#include <iostream>
#include <windows.h>

[Code].....
