Microsoft SDK and VC++ integration question.

My original project was using VC98\include\ as the directory. Recently, because I need to use one of defined valuable (PM_QS_PAINT)which is defined in Platform SDK, so I installed SDK with the option "Integrate with VC++" and move the SDK include directory to the top of the directory in options dialog in VC++. When I complied, I got compile errors from StdAfx.h like " error in ..\vc98\include\transact.h: miss ";" before some valuable.". If I removed the SDK directory below the VC++ include directory, those error disappeared, but got error for undefined valuable "PM_QS_PAINT".

Anyone knows how to fix those problem? Thanks.

There are a number of messages that get sent, and it also depends on whether you have FullWindowDragging set depending on which messages actually get sent. The previous poster answered your question with WM_SIZE, which is true. But there are more messages that get sent when you are resizing a window.

If you give a little detail of what you are trying to do, we can probably give you a better answer that will help you accomplish what you are doing.

Good Luck.

Why you cannot use GetOutputTextExtent? Performance? You can try using GetTextMetrics, but you'll have a lot of trouble...

Yes Performance. i am to calculate font size to display it with in
a rect. i am to do it for at different angles . and for for more than
200 entities at a time.
i have done it with GetOutputTextExtent but it becomes too slow.
my function is like this.

long counter=1;
long Y1 =0;
long Y2 =0;
long X1=0;
long X2=0;

if(Vertical==TRUE)
{
tfont->SetEscapement(900);
Y1=rect->top;
Y2 = rect->bottom;
X1 = rect->left;
X2 = rect->right;
}
else
{
Y1 = rect->left;
Y2 = rect->right;
X1 = rect->top;
X2 = rect->bottom;
}
while(true)
{
font->SetHeight(counter);
CFont * oldfont = pDC->SelectObject(font);
// Problem each time i am selecting it in device context to check for new
// size. that makes it slow

CSize sz =pDC->GetOutputTextExtent(*txt);

if(sz.cx>=(Y2-Y1)||sz.cy>=(X2-X1)) //text size is equal to rect
{
pDC->SelectObject(oldfont);
return counter; // so return counter;
}
pDC->SelectObject(oldfont);
counter++;
}
return counter;

Hi,

I have some relative paths (like "../../mydir/myfile.htm") to convert to absolute paths "http://www.myserver.com/mydir/myfile.htm".
Is there something like _tfullpath for file systems?

Thanks

Hi,

I need to add to my application some stuff for html generation and editing, I'm thinking about using MSHTML ( and make an small editor, with some basic stuff), or using Front Page Automation Unsure | :~

...

Is Front Page automation more or less ok ? ( I mean Word Automation is not that bad... but outlook automation seems to be hell...).

Thanks in advance, greetings
Braulio

If you use VC7 with MFC than you have a very handy class called CHtmlEditView which provides just what it promises: simple Html editing capability.

24-Oct-02 23:05

Hi,

I try to show a bitmap in my dialog based app. using the static control. I use this code:

CBitmap bmp_1;
bmp_1.LoadBitmap(IDB_BITMAP_1);

m_Bmp.SetBitmap(bmp_1);
m_Bmp.Invalidate();
UpdateData(FALSE);

This works good under Windows XP but not under windows 98.

Hi Nishant!

I think the problem to create a NON MODAL CColorDialog, CFontDialog, ... is that there is no template id for the Create(...) function! The DoModal() function of this dialogs will end in an API call!

CModeLess *m_pmodeless = new CModeLess(this);
m_pmodeless->Create(CModeLess::IDD);
m_pmodeless->ShowWindow(SW_SHOW);

For CColorDialog or CFontDialog there is no IDD!

Here is a rather sneaky way of showing a modeless color dialog :-

//Use it at your own risk
void CYourDlg::OnBnClickedButton1()
{
	CHOOSECOLOR cc;                 
	ZeroMemory(&cc, sizeof(CHOOSECOLOR));
	static COLORREF acrCustClr[16]; 		
	cc.lStructSize = sizeof(CHOOSECOLOR);
	cc.hwndOwner = NULL;
	cc.lpCustColors = (LPDWORD) acrCustClr;	
	cc.Flags = CC_FULLOPEN | CC_RGBINIT;	 
	ChooseColor(&cc);
}

Serial port communcations? I will spare the code for now but I'm having a problem I cant finger out. Not sure if overlapping will help either. I'm new to serial comm routines... If you think you can help send an email to mfeik@comporium.net. If you would like to look at my code I'll send it.. I thought this was going to be a simple dialog box interface but my reads are not proving this to be the case

There is a serial MFC class here (somewhere, sorry I'm to lazy to search the link). I used it to communicate with a microcontroller once and exchange data, it worked well.

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