Program the router to do so. For non sophisticated users, set up a firewall on the PC in question.

I'm curious, is the intent here to keep another student or classmate from accessing the Internet?

Thank, for your humour, but i search for this idea to

I see that when I step into OnHScroll() upon clicking the slider (not even sliding it, just clicking it) why does it step in three times and then finally show the adjusted display after exiting onHScroll?
Thanks,
ns

I saw that the third time, it steps in with nPos coming in as 0!!! Even though I scrolled right quite a bit, and nPos is NOT 0!. The nSBCode is END_SCROLL. Got around the problem by skipping the third step-in, but in another part of my project where the slider and SetBrightness() function both are in the same class (here they are in two different classes), the third time also, nPos is non-zero and really what it should be.
void CDlgSettings::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
pSld = (CSliderCtrl*)pScrollBar;
if (pSld !=0 && nSBCode != SB_ENDSCROLL)
{
if(*pSld == m_sliderBright)
{
m_pParentWnd->SetBrightness(nPos);
}
m_pParentWnd->DisplayLocal();
}
CDialog::OnHScroll(nSBCode, nPos, pScrollBar);
}
thanks,
ns

As Mike Dunn (I think) already pointed out, you should be doing using GetPos() to get the slider's current position and not the message-specific nPos value.

Yikes! I didnt see that response about SetPos.,.....
Thanks much! I must have missed it over the weekend.

haha! You are so funny!
Revamped my project yet again.....waiting for something new, but keep ripping up the current one and redoing it. Did a QT project a while ago.
The HScroll issue was so perplexing. Wonder why nPos cant be relied on....

It can. A closer look at the documentation will reveal that nPos is only specified for the SB_THUMBPOSITION and SB_THUMBTRACK scroll message types. When you're done scrolling, Windows sends a WM_HSCROLL message with the SB_ENDSCROLL message type. In this case, nPos is zero (as it should be).

I cannot see nothing strange here, are you sure that the "bug" is into this piece of code ??
I think Ravi is right... there's nothing that could be creating problems but of that...

i have a mdi app (using vc++ 7) and i'm trying to enable keyboard accelerators. when there is no document open, the accelerators work fine. however, when a document is open, the accelerators do not work. i added a HACCEL member to my view class, initialized it with a call to ::LoadAccelerators() and overrode PreTranslateMessage() like so,
BOOL MyFormViewView::PreTranslateMessage(MSG* pMsg)
{
if ( CFormView::PreTranslateMessage(pMsg) )
return TRUE;
return ((FAccelTable != NULL) && ::TranslateAccelerator(m_hWnd, FAccelTable, pMsg));
}
as far as i can tell, FAccelTable is initialized properly.
what am i doing wrong?
thanks.

You need to create an accelerator table (resource) for each doc template.

how do you associate the new accelerator table with the doc template? i tried using a new table with the method i described above, but it still didn't work.
|
|

Just create a new accelerator table resource with the appropriate id. The association with the doc templates happens automatically (using the id). You don't need to write any code to support this.

this is my app wizard generated code in InitInstance():
CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(IDR_MYTYPE,
RUNTIME_CLASS(CMYDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CMYView));
i created an accelerator table with an id of IDR_MYTYPE. the accelerators still do not work. is that what you were talking about?

Hi all,
Hoping for a little help with accessing portions of an .msi database from within C++ code. There are functions to access the various tables in the MFC, but for some reason I can not get them to work. So far my code is just a test that declares and MSIHANDLE and attempts to call MsiOpenDatabase. It looks like this:
#include <atlbase.h>
#include <msiquery.h>
#include <fstream>
#include <iostream>
#include <iomanip>
#include <string>
#include <vector>
using namespace std;
int main (int argc, char **argv){
LPCSTR dbPath = "\\SRV1.msi";
LPCSTR dpPerm = "MSIDBOPEN_READONLY";
PMSIHANDLE m_h;
MsiOpenDatabase(dbPath, dpPerm, &m_h);
...
For some reason, this perpetually throws LNK2001 errors (specifically _MsiOpenDatabaseA@12 and _MsiCloseHandle@4). As I'm only using MFC and ATL classes, I'm confused. Any suggestions?

Dear Forum,
I am currently developing an application in which a user must be able
to design a label.
Therefore I want to implement functionality like in the Word drawing tool, where
a user can draw a TextArea and fill in some formatted text.
When I use spy++ to try to reverse engineer how it is implemented in Word it looks
as if the Text Area is not a control. But that would mean that I would have to do
all the text formatting myself.
Can anyone tell me how to implement this and point me to some
code samples?
Thanks in advance,
Huub

Trying to implement the close all; follow up to a question I posted a few days ago.
When creating the CMDIChildWnd I register them to a list, as you suggested, and when closing them, I unregister them; it's working fine, but if I want to implement the close all window functionality, I will do the following.
The problem is that when the window is closed, it gets unregistered and removed from the list. and when going back to the CloseAllGraphicalWindow, the vector gets invalidated. and BANG !!
Is there something that I missed ?
I know I could hack this; but there should be a better way.
void CMainFrame::CloseAllGraphicalWindow()
{
ChildWindowVector_t::iterator it = m_ChildWindowVector.begin();
while (it != m_ChildWindowVector.end() )
{
CMDIChildWnd* p = *it;
p->SendMessage(WM_CLOSE, 0, 0 );
++it;
}
}
LRESULT CMainFrame::RegisterNewWindow(WPARAM wParam, LPARAM lParam )
{
CMDIChildWnd* pWnd = (CMDIChildWnd*)(lParam);
ASSERT( pWnd );
m_ChildWindowVector.push_back( pWnd );
return 0;
}
LRESULT CMainFrame::UnRegisterNewWindow(WPARAM wParam, LPARAM lParam )
{
CMDIChildWnd* pWnd = (CMDIChildWnd*)(lParam);
ASSERT( pWnd );
ChildWindowVector_t::iterator it = m_ChildWindowVector.begin();
while (it != m_ChildWindowVector.end() )
{
CMDIChildWnd* p = *it;
if ( p == pWnd )
{
m_ChildWindowVector.erase(it);
return 0;
}
++it;
}
ASSERT( 0 );
return 0;
}
Thanks a lot !!
