Hi, everyone!

I want to implement a mini-gateway on Windows platform.
Where can I get some sample codes for it? I need a gateway
that can implement basic functions, for example, check whether
a package from a certain IP address can pass through.

Thanks in advance,
George

CPropertySheet and SetDialogBkColor

I am using SetDialogBkColor to change the background color of our dialogs. Unfortunately CPropertySheet does not apply this setting. I have been able to change the property sheets background color via WM_CTRLCOLOR, but I can't seem to do this for the tab control embedded on the property sheet. I have tried subclassing the tab control, but I don't get WM_CTRLCOLOR messages for some reason. I have also tried overriding WM_DRAWITEM and WM_ERASEBGND with no success. Any ideas short of writing my own property sheet class? Thanks

CEdit painting question.

Howdy'

I want to "replace" the 3d border around a CEdit with a simple rectangle ( that I can change color when the CEdit gets and looses the focus ).

How, Where (and maybe when), should I do this ?

I try overriding the WM_PAINT, but that doesn't go well,

 // this is only an example, and I know it's not what I want at the end ...
void CCustomEdit::OnPaint() 
{
 CPaintDC dc(this); // device context for painting

 CRect rect;
 GetWindowRect( rect );
 CBrush brush;
 brush.CreateSolidBrush( RGB( 200, 0, 0 ) );
 dc.FillRect( rect, &brush );
}

I was expecting to have at least a redish rectangle drawn somewhere, or at least a red flicker... but I only get a badly redrawn CEdit.

Thanks for you input!

Max.

You can draw your own border by handling the WM_NCPAINT message. WM_PAINT is used for the client area.

It doens't work ...

This is what I do :
void CCustomEdit::OnNcPaint()

{
	CRect rect;
	GetWindowRect( rect );
	CDC* pDC = this->GetDC();

	rect.InflateRect( 10, 10 );
	CBrush* pOldBrush =pDC->SelectObject( &m_Brush );
	pDC->FillRect( rect, &m_Brush );

	pDC->SelectObject( pOldBrush );

	CEdit::OnNcPaint();
}

I think, this should fill a rectangle around the edit box.

Thanks again for your input.

Max.

Try using GetWindowDC() instead of GetDC(). also, do not call CEdit::OnNCPaint() because that will simply cause the OS to draw over any drawing you have just done. also, (part two) be sure to call ReleaseDC().

I think it's working, I now get something drawn!

But now I have to get the correct coordinates, client vs. window vs. screen ...

Thanks!

Override OnChildNotify() in the CCustomEdit. In this function check if the message is WM_CTLCOLOREDIT. If so, then uset SetbkColor function to set the background color. The WPARM value will be the handle to DC.

I have no problem with changing the background color, I just override the CtlColor for the CEdit ( with ON_WM_CTLCOLOR_REFLECT )

but I still have problem with other painting for the CEdit.

I am almost done with a beta version of an MFC appln. Now, however, I realize that when I created the appln with AppWizard I forgot to check the 'Text Sensitive Help' option. How do I go about in including that feature? I've created the help files, compiled them, but do not know how to add the feature to my appln. There must be a way! On a similar note, how would I switch from SDI to MDI? Is that possible to do after creating your programs? Thanks,
Ralf.

Hi all. Does it ever end? man. issue after issue I'll tell ya. ugh. Anyways, I have a problem performing the following:

if ((lResult = RegCreateKeyEx(HKEY_CURRENT_USER,"AppEvents\\Schemes\\Apps\\.Default\\.Default",
0,"",REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,NULL,
&hKeyResult,&dwDisposition)) != ERROR_SUCCESS)
printf("Failed\n");

if((lResult = RegSaveKey(hKeyResult,"reg.tmp",NULL)) != ERROR_SUCCESS){
printf("Failed\n");
}

The problem is I get the Key back properly, but when I try to save the Key so I can modify and set it back later on, I keep getting an error. The file does not exist when the error is returned. And I can't seem to find a simple way to get the error being returned Mad | :mad:

Any suggestions?? Thanks!

Could you check the return value from RegSaveKey? It might give you a clue.

Just what I was going to suggest. Not sure about the ".Default" entries, but I assume they are kosher.

Yeah,

The error coming back is a 1314 system error, otherwise seen as:
"A required privilege is not held by the client. ERROR_PRIVILEGE_NOT_HELD "

I finally realized that after wards.

But that doesn't make any sense to me becuase I can still delete the registry key. How is it possible that I have privileges to delete it but not to save it?? makes no sense...

thanks guys.

Alex O, maybe I should just hire you. LOL you've helped me countless times. Big Grin | :-D

Thanks
