how to create vc++ 2 D line chart taking two arraya

13-Aug-04 1:47

You should not have a problem on WinXP. I have written code that uses those parameters to GetSystemMetrics() and they return the appropriate x and y for the virtual screen when running on XP.

Can you elaborate on what you mean by not working?

Hi..

I'm sending http request in which i'm passing userID/password, then it got struck on HttpEndRequest() in case of windows XP..even on fresh Windows 98 PC.

What do you think it's reason..Is it any reason of security in WinInet or some OS file missing.

In My PC with Windows 98 it's working fine. but as I transfer it stop working,
I've checked Dependency with "Depends" & provided all files, but system Hang (Freeze) when execute function HttpEndRequest().

Plz Suggest any Solution..
Thanks..

You missed SM_CYFULLSCREEN in order to get the y.

Re: c++ winsock file x-fer

13-Aug-04 0:52

Additionally to what has already been stated.

If you have multiple monitors (or want multiple monitor support) us

SM_CXVIRTUALSCREEN to get the x
SM_CYVIRTUALSCREEN to get the y

As the parameter to GetSystemMetrics

NOTE: the rect will be (0, 0, x, y)

Can you narrow it down a bit? What exactly do you need help with? Is a piece of code giving you troubles? Do you not know how to use WNetAddConnection2()?

Hi,

I include a modeless CDialog into my program by :

m_pDlgRelance = new CDlgRelance(); // CDialog
BOOL ret = m_pDlgRelance->Create(IDD_DLG_RELANCE,this);
if(!ret) //Create failed.
AfxMessageBox("Error creating Dialog DlgRelance");
m_pDlgRelance->ShowWindow(SW_SHOWNORMAL);

But it appear always over the parent windows.
What can i do to avoid this ?

Thanks

If you pass NULL it creates the dialog with the application window as parent.
