I have a dialog box, not a doc/view architecture.
|
|
|
|
|
This solution isn't dependent on doc/view. If you want to add MRU to dialog box, use simply CYourDialog instead of CMainFrame

Thanks a lot.It works.But I have another problem.
When I open the first file from MRU menu it works,but if i want to open the rest of 4 files I get an assert:appui.cpp line 130,ASSERT(m_pRecentFileList != NULL);
But I don't have anything with BOOL CWinApp::OnOpenRecentFile(UINT nID).
I did my own function.
void CMyRtfDlg::OnFileMruFile1()
{
OnOpenRecentFile(ID_FILE_MRU_FILE1);
}
// added on 22 Apr 2004
void CMyRtfDlg::OnUpdateFileMruFile1(CCmdUI* pCmdUI)
{
m_pMRU->UpdateMenu(pCmdUI);
}
// @added on 22 Apr 2004 from appui.cpp
// @for MRU
BOOL CMyRtfDlg::OnOpenRecentFile(UINT nID)
{
ASSERT(m_pMRU!= NULL);
ASSERT(nID >= ID_FILE_MRU_FILE1);
ASSERT(nID < ID_FILE_MRU_FILE1 + (UINT)m_pMRU->GetSize());
int nIndex = nID - ID_FILE_MRU_FILE1;
ASSERT((*m_pMRU)[nIndex].GetLength() != 0);
TRACE2("MRU: open file (%d) '%s'.\n", (nIndex) + 1,
(LPCTSTR)(*m_pMRU)[nIndex]);
OnFileOpen((*m_pMRU)[nIndex]);
return TRUE;
}

Hi,
I am parsing serveral avi files and displaying the data frame by frame in
a CListCtrl. I am using the Replace function to replace each consecutive image.
How can I speed this operation up? Most of the time is spent copying the data into the
ListCtrl and the internal BitBlt which it is doing.
Regards,

Hi
In my aplication I am using a thread that waits for processes to signal their kernel objects while exiting.
I want to add the objects in the wait aray in WaitForMultipleObjects in run time dynamically.
Currently I am using the poor design that I kill the wait thread, update the array and start new thread again
Any good or better suggestion.

Cant you allocate the array using calloc and reallocating it at need using realloc while updating the count?

You can insert a Manual Event (probably at the beginning of the signal array. Then signal
this event to stop the Wait. Detect that it was your "Ahem, I want to change things" event,
rebuild the array, and loop back to the wait....?
Something like...
Rebuild_Event_Array ();
while (1)
{
dwWait = WaitForMulti (pSyncObjects, nSyncObjects, INFINITE);
if (dwWait == WAIT_OBJECT_0)
{
Rebuild_Event_Array ();
}
else if (dwWait > WAIT_OBJECT_0 && dwWait < (WAIT_OBJECT_0 + nSyncObject) )
Dispatch_Custom_Event ();
else
{
HandleError ();
break;
}
}
etc.
where Rebuild_Event_Array () puts together an array with your Rebuild event at
the beginning.

I'm haveing a lot of weird problems with a new app. I tried to create CComboBox controls and was able to add strings which I could cycle through with the arrow keys. However clicking on the arrow on the right of the box would not drop down the list so I switched to a list box. It works but for some strange reason, calling the ResetContent() method doesn't clear the items in the list box. Oddly, calling the GetCount() method shows the correct value before (n=3 or something.) and after (n = 0). The result is a list box with duplicate entries in the list box.
The code snippet is below.
Something I'm doing wrong?
{
// populate the databases ListBox
vector <cstring *=""> v;
vector <cstring *="">::iterator i;
n = _mlbDBListBox.GetCount();
_mlbDBListBox.ResetContent();
n = _mlbDBListBox.GetCount();
v = _myDBBrowser->GetDBs();
for (i = v.begin(); i != v.end(); i++)
_mlbDBListBox.AddString((*i)->GetString());
_mlbDBListBox.SetCurSel(0);
}

Are you sure that the vector does not contain the duplicates?

Yes, I thought about a corrupted vector or a problem with the vector iterator but I got the same behavior even when I added strings by hand i.e. _m.AddString("One") _m.AddString("Two"), etc.
|
|
|
|
|
So by simply calling AddString() once, two entries are added to the listbox?

Sorry, I was confusing the CComboBox/ListBox behavior. The list box worked correctly when initially loaded with strings, either by hand or from the vector. When I tried to refresh the data in the list box, I called the ResetContent method of the list box. It returned values that indicated all the items had been deleted. The I added new items but it then displays two sets of items.

Very strange. Can you create a new dialog-based application that mimicks this behavior? Trying to scale the problem down to just a few relevant lines of code is sometimes very helpful.

Got it worked out. Weird. I was creating controls at work on an XP machine. Carried it home to my 2000 machine and the controls were all created correctly except that they had zero sizes. Once I went in and "resized" them with the InterfaceBuilder everything was fine.
Thanks

Hi guys
I'm having troubles with resources in w98 and one of the questions is the following.
I'm using a resource meter to know the GDI resources available, and when I open a CDialog with a lot of controls (>100), the resources go down and when I close it the resources don't raise again until I close the app.
Is this normal? If not, what can be the cause?
I'm using a lot of CLabel controls (derivesd from CStatic controls classes get it here in codeproject)
Best Regards
Doc

No, it's a memory leak. Some of your controls are creating resources and not cleaning them up. From the sound of it, probably fonts.

Without using MFC how can I tell if the mouse is over my buttons?
I've tried WM_NCHITTEST and WM_MOUSEMOVE along with stuff like ScreenToClient, GetDlgItem, GetDlgCtrlID, ChildWindowFromPoint, ect, but nothing seems to be working.
Any Ideas? Some code would help me out, thanks.

Just do subclassing for CBUtton
e.g
CYourButton : public CButton
{
.
.
};
and AAdd message Handlers
ON_mouse_Move
regards

Can't do that, I'm using pure WIN32 API, no MFC (if I wanted something like MFC I would use VB).

may i know , what are you using. is it SDK , and if so you might have register the class, in WinProc you will receive all the messages

You do not need MFC to subclass button controls. You write your button's window procedure and use SetWindowLong() with the GWL_WNDPROC index to subclass the button.
LRESULT CALLBACK MyButtonWindowProc(HWND hWnd, UINT nMsg, WPARAM wp, LPARAM lp)
{
switch (nMsg)
{
case WM_MOUSEMOVE:
default:
return DefWindowProc(hWnd, nMsg, wp, lp);
}
return 0;
}
SetWindowLong(ButtonHwnd, GWL_WNDPROC, (LONG)MyButtonWindowProc);
