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.

Special behaviour of a CEdit-control in a CDialogBar:
My CDialogBar is a member of my MDI-mainframe-class. The menu of the mainframe have an item with an accelerator "r".
Now, if I want to type the letter "r" in my CEdit-control, the menu-item (with the accelerator "r") will be called.
How can I type "r" into the CEdit-control? How can I handle it?

I have a child window above an edit control.
When the position of the control in the parent in the child on top of it is clicked the control gets topmost. Is there any way to prevent this?

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?

I want to get the row and column of an Control that has been added to a TableLayoutPanel. This is what i've got so far:
I add the control at the begin in the Form_Load event:
this.tableLayoutPanel1.Controls.Add(this.userControl1, 1, 1);
private void tableLayoutPanel_Content_ControlAdded(object sender, ControlEventArgs e) {
int column = tableLayoutPanel1.GetPositionFromControl(e.Control).Column;
int row = tableLayoutPanel1.GetPositionFromControl(e.Control).Row;
if(row == 1 && column == 1) // Later i want to check it like this
}
The problem is, that the column and row are always 0, but why?

I have problems to show a tooltip for a ClistCtrl.
I searched for some solutions in the web.
I found only solution where derived classes are used.
Is it no possible to use tooltips in ClistCtrl without a derivate ClistCtrl?

I have a ListCtrl on my dailog. It has a report view. In my case I have selected first row with left click of mouse and entire row is displayed in blue color as selection (as per expected) and when I right click the second row of the listctrl it displays the menu which I have added to it and the selection remains with the first row.(as expected). I have already overridden the ListCtrl class.
I want that on the right click of second row the selection should remain with the first row but this second row also should be displayed with dotted line border.

I'm working on an app which monitors user selected data sets from various devices, and I'd like to display the data in a CListCtrl. This would be very convenient, but I'm just a little concerned about (1) just how fast can a CListCtrl be populated, and (2) how can i reduce or eliminate screen flicker. To be specific...
1. There will likely be upwards of 100 rows of data, maybe more (probably 5 or 6 columns), and I'm going to have to refresh it all as quickly as possible, perhaps as fast as once per second. I can play games and only refresh a visible rectangle, but how responsive the control would be, having all that data deleted and refreshed continually?
2. You can see why I'd be worried about screen flicker, and I thought I'd likely have to make two identical overlapped controls so I could double buffer as I would with a graphic animation, switching the visibility of one or another control after its updated to give the appearance of sudden complete updates. BUT... I see there is an extended style you can set called "LVS_EX_DOUBLEBUFFER"

I need a ownerdraw CListBox where I can change the item height during working with the list. The msdn says that I can specify the height in OnMeasureItem when the listbox will be created (ownerdrawfixed) or when an item will be inserted (ownerdrawvariable).
How to change the height e.g. when I click a button?
I made also some tests with CListCtrl. There I can change the height. But there is only one height for all items. How to set individual heights for the items?

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?

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.

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);
//..

One exercise says that, "Define a right triangle class. Make an octagonal shape out of eight right triangles of different colors."
Making such a class isn't difficult. I wrote it as follows:
Code:
#include "Simple_window.h"
class right_triangle : public Shape {
public:
[Code]...
But it sounds that making an octagon using eight right triangles isn't possible!
