Re: Intializing a structure array to store SQL Results from a class

30-Dec-11 12:40

I thought I had to dimension the array first, guess that's not needed if I write better code.

Well here goes, finished my dialog form, so I'm back to the array now.

You might want to experiment with some simpler arrays first. I would suggest an array of ints then an array of strings (the string class, not a char*).

Allocate the arrays, assign values to members of the array, then sequence through the array to verify, then deallocate the array.

After that your implementation is just a variation on the above (especially since string is a class so you will have already created an array of classes.)

That's a good idea. I will start with some small simple arrays first and get the hang of it in c++, then take it from there.

Thanks jschell

In MFC, UNIT how to convert an int,can you help me? Master

Just like that :

C++

int i = 0;
UINT u = 9;
i = (int)u;
TRACE("%d\n",i);

C++

int i = 0;
UINT u = 9;
u = (UINT)i;
TRACE("%d\n",u);

Assuming that you mean UINT rather than UNIT you just need to cast it thus:

C++

UINT uIntValue = 100;
int intValue = uIntValue;

Be aware that any values greater than 2147483647 (0x7FFFFFFF) will be negative in the resulting integer.

Thank you, I understand. But the source is so written.

for (UINT uiLineStyleCmd = ID_LINE_STYLE_1;
uiLineStyleCmd <= ID_LINE_STYLE_10;
uiLineStyleCmd++)
{
int iIndex = pMenuPopup->GetMenuBar ()->CommandToIndex (uiLineStyleCmd);
if (iIndex >= 0)
{
pMenuPopup->GetMenuBar ()->m_bDisableSideBarInXPMode = TRUE;
//----------------------------
// Obtain item text and style:
//----------------------------
CString strText = pMenuPopup->GetMenuBar ()->GetButtonText (iIndex);
UINT uiStyle = pMenuPopup->GetMenuBar ()->GetButtonStyle (iIndex);

//------------------
// Calc. line width:
//------------------
int nWidth = uiLineStyleCmd - ID_LINE_STYLE_1 + 1;

//-------------------
// Replace menu item:
//-------------------
pMenuPopup->GetMenuBar ()->ReplaceButton (uiLineStyleCmd,
CLineStyleMenuItem (nWidth,
uiLineStyleCmd,
strText,
uiStyle & TBBS_CHECKED));
}

Please do not use direct eamil to update details of open issues.

You responded to my question:

Message from dlsyaim:

Source is defined so
#define ID_LINE_STYLE_1 32833
 
But UINT 0 - 4294967295 
Source code is no problem

What exactly does this mean, and what is your problem?

In MFC. I added BCGControlBar control, I do not know how to load line type, source of these. Our manager let me look at this change.

return FALSE;
}

pMenuPopup->RemoveAllItems ();

CMenu menu;
VERIFY(menu.LoadMenu (IDR_POPUP_TOOLBAR));

CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);

pMenuPopup->GetMenuBar ()->ImportFromMenu (*pPopup, TRUE);
}

Is this the statement in question? If so, what is the compiler error or warning that you are receiving?

Hi. I have a SDI app, with CView based on CListView. In edit menu, I enable / disable some items dependes some conditions with :

C++

ON_UPDATE_COMMAND_UI(ID_EDIT_REFRESH, OnUpdateEditRefresh)

the same edit menu I load in right-click :

C++

void CMyView::OnRclick(NMHDR* pNMHDR, LRESULT* pResult)
{
	// TODO: Add your message handler code here and/or call default

	NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

	CMenu menu;
	menu.LoadMenu(IDR_TERMTYPE2);
	CMenu* pContextMenu = menu.GetSubMenu(1);

	POINT point;
	CPoint pt(pNMListView->ptAction);
	point.x = pt.x;
	point.y = pt.y;
	::ClientToScreen(pNMHDR->hwndFrom,&point);

	int nID = pContextMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON | TPM_RETURNCMD,point.x,point.y,this);

	*pResult = 0;
}

but all items from edit menu are enable ... and I must enable/disable depndes by the same conditions like main edit menu ... my question is, how can enable/disable edit menu items in OnRclick handler but some how using ON_UPDATE_COMMAND_UI ?

Re: win32 api - some kind of control container

I made a window that holds a listbox of users, you click on one, and you can edit the values. I was going to make a new window, and tried a dialog box, but there was no textboxes, I didn't find one.

So now I'm thinking, just create 2 panels or groups, and toggle them show and hide.

Question:

Is there such a thing in c++ win32, and what would it be called>

Jim,

I have absolutely no idea what you are describing. Maybe it has something to do with the post below yours... I can't get this Tic-Tac-Toe song by Kyper[^] out of my head now.

Maybe you could give a better description of what you are attempting to do. Keep in mind that most of the window classes are very basic in what functionalities they provide.

I want to group a collection of textboxes, labels and buttons, and store it as a single object that I can make visible or invisible.

I was just thinking maybe a plain CreateWindow could do the job, but for now, I'm not sure if it's possible to do, and the name it would be refereed to as - nomenclature.

I am sure that you are already familiar with the parent/child relationship with windows; If you hide a parent window all of its children are non-visible.

Intentional paronomasia: Thinking outside the box... In your InitDialog() or perhaps OnSize() you could get the rectangle of the group box and set all windows with the Top/Left point that are within the group box rect... to be child windows of the group box. Now when you hide the groupbox... all child windows will also be hidden.

It may also be be possible to do something with ON_CONTROL_RANGE[^] to control/hide all of them at once. All you need to do to implement this is give them ID's of a contiguous range... 100, 101, 102, 103, 104, ...

That's all I can think of for now.

Best Wishes,
