I believe you can do it through the ODBC SDK functions. Look up "ODBC Function Summary" and "SQLConnect". You will have to learn about ODBC data sources and the like. This is not trivial. MFC is definitely WAY easier.

You also may have to download/install the Microsoft SDK to get access to those functions (not sure about that). It is a free download. Good luck!

Mapping a drive in a program

I need a little app (I'll write it if I have to) that when a server becomes availible (due to a VPN connection being established) will map a drive off that server to the client.

Can someone point me in the right direction on how to do this in a windows app for 95-XP.

Technically, I just need to know the API calls, and what hoops I mist jump through.

Thank you.

Dynamic creation of MFC controls & message handling

Hi,

The code to create new MFC controls on heap is available on the net.

<br />
CButton *pMyButton = new CButton();<br />
pMyButton->Create( ... );<br />
/* delete pMyButton at appropriate time */<br />

Can someone explain how to do message handling for this dynamically created button? Thanks in advance.

One solution is to ass message handlers for the buttons via their ID which you passed into Create().

ON_BN_CLICKED(ID, Handler().

I have a tabctrl that controls 2 tabs(dialog each). I want each
dialog(tab) to be informed when it is selected/deselected. How do I get the tabctrl to inform the tab children dialogs that this event has occurred.
Thank you

This may be kind of kludgy, but I can listen for the change indirectly by listening for the OnPaint message from the framework.

if you are using mfc you have the TCN_SELCHANGE if not WM_NOTIFY and the same message !

on MFC :
switch(tab.GetCurSel())
{
case 1:
dlg1->YouROn();
dlg2->YouROff();
break;
case 2:
dlg1->YouROff();
dlg2->YouROn();
break;
default:
dlg1->YouROff();
dlg2->YouROff();
break;
}

on win32 sdk way :

int GetCurSel(HWND tab)
{
return SendMessage(tab,TCM_GETCURSEL ,0,0);
}

void OnTabCtrlSelChanged(int idTabCtl, HWND tabWnd)
{
here use the MFC switch i showed above
}

case WM_NOTIFY:
switch(((LPNMHDR)lParam)->code)
{
case TCN_SELCHANGE:
OnTabCtrlSelChanged(((LPNMHDR)lParam)->idFrom,((LPNMHDR)lParam)->hwndFrom);
break;
}

Everybody knows the standard windows audio mixer (sndvol32.exe). I want to develop such a mixer and replace the old one.

(I think) I known enough to create such an application once I've started and chose a direction.

The thing is, how do I do this? Should I use the shell api for this, or can I do it with dx9? Or do I have to retrieve some com-dispatch and event-sync?

Once I've determined the api to use, the hard part is over...

Does anyone have some suggestions?

using: [VISUAL STUDIO 6.0 sp5] [WIN98/2]

I've searched around on my machine and found out that sndvol32.exe uses the winmm.dll to control the audio.

I guess I have to bet on that horse...

Or not?

In Windows 2000 DDK there is one Utility named newdisp. That helps in updating display driver without restarting mahine. Is it possible to load totally different display driver dyanamically with restarting the M/C ?

Multiple Form view

13-Mar-03 22:22

Hi all!

Something tricky Smile | :)

!!
I have an SDI application wich View class is derived from CFormView.

First, I need another View (also derived from CFormView) displayed on the screen with the first one (like a splitter view but using two or more CFormView derived classes).

Second (and that becomes trickier), I need to change the first view to another CFormView derived class but WITHOUT replacing the other FormView (this one must always been showed on the screen, it's just the first pane who is changing his view).

Can anybody give me some guideline to follow ? (I'm not very familiar with MFC Smile | :)

)!
Thanks a lot!

Nice puzzle. One solution is MoveWindow() and SetWindowPos(). Try out those functions to show and hide the views.
