What description does the exception object contain >?
Did you check the permissions of the remote share ?
It should have permissions to write since the
lock file is created in the same place as the database.

In the debug tab of your project settings, add the filename to the argumenst that would be passed through on the command line. You can then run in debug mode from VC.

UINT _Junk;

// turn off ctl-alt-del
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING,1,&_Junk,0);

// ... do stuff? like what?

// turn on ctl-alt-del
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING,0,&_Junk,0);

According to MSDN you shouldn't use SPI_SETSCREENSAVERRUNNING (look up SystemParametersInfo for details). Would SPI_SETSCREENSAVEACTIVE help here? - I don't think it would but it might be worth a try Unsure | :~

If you have MSDN there, look up the article called 'HOWTO: Disable Task Switching on Win32 Platforms' - it talks about low level hooks to achive the goal. If you find an easier / better way please post a reply here for the rest of us!

Visual .NET Debugger on 6.0 C++ compiler

8-Jul-02 1:36

Hi there,
Just back from Barcelona for Tech-Ed 2002, and I saw in same presentations
that it was possible to use the new debugger shipped with Visual c++ with
the 6.0 compiler:

The question is:

1. How to do it?
2. I can still use after on the same machine
the debugger .NET with compiler 7.0 (Unmanaged C++)

Thanks, claudio

Hello,

i want to change the buffer contents of the CArchive or of the attached
CFile Object. But it is not allowed to make a write access in the "loading path" of serialization. I don't want to override the CArchive class.

Any solutions ?

Thanxs !

I have positioned an ActiveX control onto a tabsheet control. I now want the ActiveX control to resize with the window. For some reason i don't get the desired result, can nayone see where i am slipping up.

Thanks
Richard

Code Fragment:

Init Dialog - Creation of the ActiveX Control

m_tabSheet.GetWindowRect( &rc );
ScreenToClient( &rc );

rc.top += 30;
rc.bottom -=90;
rc.left += 5;
rc.right -= 40;

m_controlWrapper1.Create(m_hWnd,rc, _T("MSCAL.Calendar"), WS_CHILD, ....)

Resize Event
=============
RECT tabRC;

m_tabSheet.GetClientRect(&tabRC);

ScreenToClient( &tabRC );
tabRC.top += 30;
tabRC.bottom -=90;
tabRC.left += 5;
tabRC.right -= 40;

m_controlWrapper1.SetWindowPos(CWnd::wndTop, tabRC.left, tabRC.top,tabRC.right - tabRC.left, tabRC.bottom - tabRC.top,SWP_SHOWWINDOW);

One thing is that I think you'd better use the MoveWindow function instead of the SetWindowPos function in that case.

Have you checked the the coordinate don't reach something like a bottom higher than a top...

Task Bar in Full Screen Mode Implementation

I want implement full screen mode in my small application. I wrote codes
as follows:

cx = //width of the screen;
cy = //height of the screen;
SetWindowPos (hwnd, NULL, -4, -4, cx, cy, SWP_NOZORDER | SWP_FRAMECHANGED);

They work pretty well, the minor boring thing is that the task bar (if Not
autohide) is still there. it will not disappear unless I click it once? any
solution? thanks, thanks.

Very close Nish, but if you want to make the window topmost, you have to drop the SWP_NOZORDER flag

Dear,
What I've used are:

<br />
int cx = GetSystemMetrics (SM_CXSCREEN);<br />
int cy = GetSystemMetrics (SM_CYSCREEN);<br />
int cyCaption = GetSystemMetrics(SM_CYCAPTION);<br />
int cyMenu = GetSystemMetrics(SM_CYMENU);<br />
SetWindowPos (hwnd, HWND_TOPMOST, -4, -(cyCaption + cyMenu + 4), screenx + 8, screeny + (cyCaption + cyMenu) + 8, SWP_FRAMECHANGED);<br />

Future of C++ in MS Windows?

Hi,

I've recently installed .NET and is familiarizing myself with it right now. With
the common-runtime and C# is C++ getting less love from MS? I've been developing
with VC6.0 for some time now and I like it ok, but the .net release seems
to be moving in a general direction away from c++.

I am just wondering about the future of my favorite language?

Is the future with c# now? Or is it managed c++?

Is MFC or ATL based apps outdated now?

In essence, I'm wondering what I should focus on in the .Net world?
Confused | :confused:

I say learn C# but don't bail on C++. For starters, they have put a lot into standards compliance, with more to come, and that has got to be a good thing.

I agree about the standards compliance. That is a good sign.

Thanks for the advice, and I think I'll follow it and learn c#.

I'm still interested in more comments from others as well.

My strategy for developing .NET applications is to use C# for the UI and database handling and use managed C++ for the system calls and stuff that the Framework doesn't support (such as TAPI, MAPI)

Managed C++ is a nice option. You can mix .NET stuff with MFC and ATL all in the same cpp file Smile | :)
