Re: How to delete entire row in CListCtrl?

Hi,
You do the following,
m_LCtrlPtr->DeleteItem(m_LCtrlPtr->GetSelectionMark());

This will delete the currently selected item in the list control.

GetSelectionMark() is to retrieve the currently selected item.

hope this helps!!

Hi,
if you need to find the selected item in a listcontrol, there is no function, to do it.

In your code for deleting a row you may use this to find the desired index

	<br />
  long lx;<br />
  LV_ITEM lvItem;<br />
  lvItem.iItem     = 0;<br />
  lvItem.iSubItem  = 0;<br />
  lvItem.mask      = 0;<br />
  lvItem.state     = 0;<br />
  lvItem.stateMask = 0;<br />
<br />
  if(m_VarForListCtrl.GetSelectedCount() != 1 ) return;<br />
  // if none or more than one are selected bail out<br />
<br />
  int  iItem = m_VarForListCtrl.GetTopIndex();<br />
  int  iMax  = m_VarForListCtrl.GetCountPerPage();<br />
  for( int i = iItem; i < ( iItem + iMax ); i++)<br />
     { lvItem.iItem     =  i;<br />
       lvItem.iSubItem  =  0;<br />
       lvItem.mask      = LVIF_STATE;<br />
       lvItem.state     = LVIS_SELECTED;<br />
       lvItem.stateMask = LVIS_SELECTED;<br />
       if( !m_VarForListCtrl.GetItem(&lvItem) )<br />
         { return; // if item can't be read, do nothing<br />
         }<br />
       if( lvItem.state ) break;// found item<br />
     }<br />
  if( !lvItem.state ) return; // no item found<br />
  // lvItem.iItem now has the index of the selected row<br />
  m_VarForListCtrl.DeleteItem(lvItem.iItem);<br />

This code wil find only the selected item if it's visible.
You must adapt the code, if you are searching the whole list.

Was it this you were looking for?

DWORD dwstyle = m_myListControl.SendMessage(LVM_GETEXTENDEDLISTVIEWSTYLE,0,0);
dwstyle |= LVS_EX_FULLROWSELECT;
m_myListControl.SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE, 0, dwstyle);

this is the hard way, but in VC5 it was the only way to get it work properly.

hope it helps

hi:
the issue is solved it should have been like

CButton* pButt=(CButton*)GetDlgItem(IDOK);

DWORD newstyle = ::GetWindowLong(pButt->m_hWnd, GWL_STYLE) | BS_ICON;
::SetWindowLong(pButt->m_hWnd, GWL_STYLE, newstyle);

CWinApp* pApp=AfxGetApp();
HICON hIcon=::LoadIcon(pApp->m_hInstance,MAKEINTRESOURCE(IDI_CLOSE));
if(hIcon==NULL)AfxMessageBox("null icon");
pButt->SetIcon(hIcon);

return bResult; Smile | :)

How do I hide the second apps Main Window??

Hiya, I have 2 apps, one calling the other with CreateProcess(). How do I hide the second apps MAIN WINDOW when called??

CreateProcess takes a LPSTARTUPINFO lpStartupInfo,
and in it u have a WORD wShowWindow; which u can set to SW_HIDE

while (TRUE)

if you invoke a console application , there is some flags in CeateProcess API itself.

the 6 th argument dwCreationFlag - put CREATE_NO_WINDOW
will hide the coonsole window.(not applicable for MS_DOS programms).and remember this only valid for WIndows NT/2000/XP Operating systems

there is another method you can follow if u creatw with WinExec() API, the second argument is the window style...just put WS_HIDE Wink | ;)

simple but a little dirty way...;)

OK, thanks. Have done this:

ZeroMemory( &StartupInfo,sizeof(StartupInfo) );

StartupInfo.cb = sizeof( StartupInfo );
StartupInfo.dwFlags = STARTF_USESHOWWINDOW; // Problem line
StartupInfo.wShowWindow = SW_HIDE; // Problem line

if( CreateProcess( lpApplicationName,lpCommandLine,
NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo ))
{
WaitForSingleObject(ProcessInfo.hProcess,INFINITE );

CloseHandle( ProcessInfo.hThread );
CloseHandle( ProcessInfo.hProcess );
}
else
{
AfxMessageBox( "Error - Opening Invoicing" );
return;}

As soon as I put the StartupInfo.dwFlags and StartupInfo.wShowWindow lines, it fails. It leaves a white shape of my dialog I just called and then errors.

Am I putting these in wrong..

Thanks,

Just as a side note,

<br />
  STARTUPINFO StartUpInfo;<br />
  ZeroMemory( &StartupInfo,sizeof(StartupInfo) );

is just the same as
STARTUPINFO StartUpInfo = {0};

but the latter is shorter and IMHO more to the point.

My opinions may have changed, but not the fact that I am right.

Antialias TextOut

We have an MFC app with a 'dynamic' splash screen. It uses dc.TextOut to paste text from the version resource over a background bitmap. To make it look a little cooler, I'd like to be able to antialias the TextOut output.

Is this possible? Anyone have an tips? I can't find anything that looks helpful....

When you create your font, you can pass ANTIALIASED_QUALITY for the nQuality parameter to specify that the font should be drawn with antialiasing if available (and applicable for that point size).

Hope this helps.

You must to import the excel.tlb library with the classwizard.
Then you will have the classes that permit tou to access to Excel with OleAutomation.
When you will have acces to each cell you will can import o export data by program.

2 subclass for 1 item

Hi
Is it possible to subclass 2 times a Edit field.
Like the first subclass, makes sure only the correct information is entered.
This subclass is used for like 5 items.
But on 1 item i want to change the textcolor. So i made another subclass, which i tested out in another project (worked well).
But i get a 'Debug Assertion Failed, wincore.cpp line 312' error.
Can't i subclass an item twice?

Greetings
Jens

Yes, a class can be derived from multiple base classes.

class CCorrectInfoEdit : public CEdit
{
};

class CColoredEdit : public CEdit
{
};

class CMyEdit : public CCorrectInfoEdit, public CColoredEdit
{
};

This is not nearly enough information. CWnd::Attach() is where your problem shows, but the 'Why?' is something completely different.
Please show more about what you called when the error occured

I've got an editbox IDC_EDIT which is attached to a control CString m_edit by classwizard.

Then i've subclassed on InitDialog()
CCheckNumber acEditNumber;
acEditNumber.SubclassDlgItem(IDC_EDIT, this);
-> this checks if input is ok or not.

Now i add:
CColorEdit acColorEditNumber;
acColorEditNumber.SubclassDlgItem(IDC_EDIT, this);
acColorEditNumber.SetTextColor(RGB(250,0,0)); // RED

the program crashes when i subclass the IDC_EDIT again.
But 'ColorEdit' works fine.

And i don't know how i can trace at what line the error occured. When i remove the 2de subclass, programs runs ok.
