I am getting an assertion failure in the last line of this function. When I click the 'Ignore' button, I am getting a message box with the message
'Unsupported operation was attempted'.
I donot have any clue to fix it?

Pl help me.

BOOL displaydlg::OnInitDialog()
{
CListCtrl *plistb = (CListCtrl *) GetDlgItem(IDC_LIST2);

LV_ITEM lvI;
// Initialize LV_ITEM members that are common to all items
lvI.mask = LVIF_TEXT | LVIF_PARAM | LVIF_STATE;
lvI.state = 0;
lvI.stateMask = 0;
lvI.iImage = 0;

CString str;

int i =0;
if (m_pSet1->IsOpen()) {
m_pSet1->Close();
}
m_pSet1->Open();

while (!m_pSet1->IsEOF()) {

lvI.iItem =i;
lvI.iSubItem = 0;
str = m_pSet1->m_Type;
lvI.pszText = (LPSTR)LPCTSTR(str);

lvI.cchTextMax = MAX_ITEMLEN;
lvI.lParam = (LPARAM) i;
if (plistb->InsertItem(&lvI) == -1)
AfxMessageBox(_T("ListSelectData::FillListCtrl error"), MB_OK);

i++;
m_pSet1->MoveNext();
}

return CDialog::OnInitDialog();
}

are there any records in the recordset?

Yes, having 3 records.
If i comment out return CDialog::OnInitialUpdate() and return TRUE, then I am not getting this assertion failure. Only after the dailog with the listctrl filled with the records, the assertion failure appears.

try this:

call CDialog::OnInitDialog first in your function (not last). then return FALSE.

I fixed the problem.

The assertion failure is thrown when calling DoDataExchange();
CDialog::OnInitialUpdate() calling CDialog::UpdateData(FALSE) calling CDialog::DoDataExchange(..).

Actually I had an button control in the dialog and an corresponding button variable in the Dialog class and hence the DoDataExchange() had an line containing button variable. Then I removed the Button variable from the resource. But didnot remove from the code.

I tried to remove the button variable from the Dialogs class and DoDataExchange() and thus it worked.

Thanks for your help. Sorry for the trouble.

text in resource editor?

Hi guys.
I was wandering if it's possible to have a long text as a resource and then how to show it in a Dialog based application.
Do you have any suggestion to keep the long text inside the final ex file?
Thanks in forwarding.

Put it in your application as a custom resource:

In your .rc2 file
MYTEXT TEXTFILE "Somefile.txt"

To get the text

HANDLE handle = ::LoadResource(hInstance, ::FindResource(hInstance, "MYTEXT", "TEXTFILE")) ;
char *pText = (char *)::LockResource(handle) ;

Dynamc Pop-up Menu?

Hi,

I need to put together a context menu within an app that can display options that aren't known at compile time. I can create a normal pop-up menu alright I just don't know where to look to
populate the menu with items that are, for instance, defined in a user configurable file.

Any Ideas???

If you are using MFC, you can use CMenu methods like AppendMenu.
Following code snippet loads menu from resources and adds a separator and a dynamic menuitem:

void CMyView::OnContextMenu(CWnd* pWnd, CPoint point) 
{
	{
		if (point.x == -1 && point.y == -1){
			//keystroke invocation
			CRect rect;
			GetClientRect(rect);
			ClientToScreen(rect);

			point = rect.TopLeft();
			point.Offset(5, 5);
		}

		CMenu menu;
		//You can optionaly load a static part of the menu from resources
                VERIFY(menu.LoadMenu(IDR_CONTEXT_MENU));

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

		pPopup->AppendMenu(MF_SEPARATOR);
		pPopup->AppendMenu(MF_STRING,1111,"Dynamic");

		CWnd* pWndPopupOwner = this;

		while (pWndPopupOwner->GetStyle() & WS_CHILD)
			pWndPopupOwner = pWndPopupOwner->GetParent();

		pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,
			pWndPopupOwner);
	}
}

If you want the menu completely dynamic, then add a MF_POPUP instead of LoadMenu.

Thanks Pavel,

That'll work great. My next question is how to map commands to the dynamically added menu items?

Sorry I can't help you, but I had the same problem.

I dynamically create a menu that contain a certain number of IP adresses, like :

_TRAYMENU_
192.168.0.1
62.43.12.10
etc...

and I want to copy the IP to the clipboard when I click on it (I know for the clipborad, but I don't know how to map commands...)

Thanks!

Look up the DYNAMENU sample in MSDN. It details how to do this stuff.

Add an ON_COMMAND or ON_COMMAND_RANGE macros to the message map section of the class where you want to catch them:

BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWnd)
	//{{AFX_MSG_MAP(CMainFrame)
	ON_WM_CREATE()
	ON_COMMAND(ID_VIEW_DLLTEST, OnViewDlltest)
        ... and other macros added by class wizard
	//}}AFX_MSG_MAP
	ON_COMMAND(ID_xxxx, OnXxxx)  //<<< manually add the handler mapping here
END_MESSAGE_MAP()

You also need to add the void OnXxxx() method to your class.

Mouse and Keyboard question

Hello everybody:
I want a function to be exectured when I press CTRL + Click over a bitmap image in a Dialog. I know how to do that when I to a Ctrl + Click over the Dialog itself using the OnLButtonDown() function. What do I need to do to make it happen by just clicking the bitmap image? Any answer is more than welcome.

Place the bitmap in a static text control on your dialog. Give the control a unique ID and set the notify style for it. You can then write a handler for BN_CLICKED for the static control and check to see whether the control key is pressed (GetKeyState(VK_LCONTROL) || GetKeyState(VK_RCONTROL))

Hello:
I tried what you told me and this is what I put in my code:

void CMyClass::OnPicClicked() <br />
{<br />
	  // TODO: Add your control notification handler code here<br />
	<br />
	if ((GetKeyState(VK_LCONTROL) || GetKeyState(VK_RCONTROL)))<br />
	{<br />
               //MY STUFF HERE<br />
	}<br />
}

Does that looks correct? I run my application and it doesn't work.

Thank you for your reply.

In my previous post I told you that I didn't work. I take that back. It works. I forgot to set the notify style for the CStatic. Works perfect. Thank you very much.

CDocument::SetTitle and split views?

dazinith11-Sep-02 3:58

dazinith

11-Sep-02 3:58

hio!

i have a split view that i am using, and whenever i replace any view i set the documents title.. the problem is that when i click inside of a field in any of these views the title somehow gets set to the filename of the document (which i beleive is the default of CDocument::SetTitle)

any suggestions? here is an example of how im setting the title:

void CMainFrame::ShowHeader()
{
	CView* pView = GetActiveView();
	CMyDoc* pDoc = (CMyDoc*)(pView->GetDocument());
	m_wndSplitter.ReplaceView(0,0,RUNTIME_CLASS(CHeaderView),CSize(500,HEADERHEIGHT), pDoc);
	SetDocTitle(pDoc, pDoc->m_pComp, pDoc->m_pLoc); // set the title appropriately
	m_wndSplitter.LockBar(false);
}

the SetDocTitle() just calls the document's set title function with it formatted the way i want it to look..
