OK.
Handle the OnEraseBkgnd() like this:
.... OnEraseBkgnd(CDC* pDC)
{
CRect rect;
GetClientRect(&rect);
pDC->FillSolidRect(&rect,RGB(255,0,0));
return TRUE;
}
The events list for a dialog box does not normally display this message to be handled in VC6. You need to change the "Filter for messages.." combo box to "Window".
Now the background will be bright Red.
To change the foreground, do you mean Static text etc?
Then you will need to subclass the CStatic, and handle its painting yourself. You can find many CStatic samples here on CP.

this is this.

my plotting application draws data in a window 400 pixels high 600 pxl wide.....x axis represents seconds(1 sec=2 pixel) how to scale the y-axis to plot larger values larger than 400,

thanks

Hello,

The following formula will help you to determine the amount of y - value amounts per pixel you need to plot your largest value:

ValuesPerPixel = Height / (MaxValue /* + spacing */)

You must wonder why to add a spacing. This is because you don't want too look that your graph goes out of the screen. You want to top to be clearly visible.

Hope this helps.

Hi All

I am willing to take the back up of registry (Key, Subkeys & Data) to other place(it may be hard disk, CD\DVD, LAN or any other media). also restore it to any specified location.

How will I do this?

What is the path where registry entries are stored?

Please Reply.

Thanks & Regards.

Your explorer may not show it by default unless you set to view hidden and system files through folder options-View

Use RegSaveKey() and RegRestoreKey() for this.

Of course. What did you expect with Windows 2000 Pro? Those other .dat files you referenced are for Windows 9x and Me.

Funny you should ask. I just read such a magazine article just a few weeks ago that went into painful detail how the registry was laid out. Unfortunately, I can't find that magazine. I've looked through all of my magazines and my browser history but I can't find it. That's so aggravating. Frown | :(

If I stumble across it in the future, I'll let you know.

Windows Service with network access

Anonymous14-Sep-05 0:05

I am creating a service which tries to access some files on a remote computer.
But seems my service has not right to access the files.

Can anybody suggest a method to solve this problem or give me some sample to refer to?

thanks in advance~

By default any service is registered to run as a special user called "SYSTEM", but this user does not have access to network resource. So you can register your service to run as a different user when you create it using CreateService(). the following two parameters of the function will do the trick I guess.
LPCTSTR lpServiceStartName,
LPCTSTR lpPassword

Otherwise you can manually change the user name after its created also using SCM->"Your Service"->Properties->Log on->This Account.

gamitech13-Sep-05 23:38

13-Sep-05 23:38

I have application that scans for files (exe's and dll's) and looks up thei import table.

I have managed to see what functions they import with IMAGE_NT_HEADERS IMAGE_IMPORT_HEADERS IMAGE_THUNK_DATA.
i compare the c***ion pointer from
pThunk->u1.FisrtFunction with my function loaded with GetProcaAdress()
it works fine but how do I get the function name from IMAGE_THUNK_DATA structure
i've tried
WORD hint=(WORD)&pThunk[l]->u1.AddressOfData->Hint;
PSTR FNAME=(PSTR)((BYTE *)hMod+pThunk[l]->u1.AddressOfData->Name[hint]);

doesn't work what is the correct combination ?

Handle the WM_CLOSE message of the second dialog. Just Hide the dialog instead of destroying it, like: ShowWindow(SW_HIDE); Also handle the OnOK() and OnCancel() functions, so that the dialog cannot be destroyed.

Create the second dialog in the OnInitDialog() of the first dialog. Keep the handle of the second dialog as a member variable in the first class, like:
CSecondDialog m_SecondDialog;

In the OnInitDialog() of the first:
m_SecondDialog.Create(IDD_WHATEVER,this);

When you need to show the second dialog, just show it:
m_SecondDialog.ShowWindow(SW_SHOW);

this is this.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
