Hi all,
I've made a translucent window in win2k/sp3/vc++6/sp5
using WS_EX_LAYERED and SetLayeredWindowAttributes(). When
I then right click the window body and make it popup a
context menu, I see the displaying of the selected menu
item terribly disturb by that (background) layered window.
It seems the layered window gets a higher z-order and then
tries to show above the menu.
Try this for a clear idea of it:
------------------------------------
1. goto: http://www.codeproject.com/dialog/smoothalpha.asp?target=setlayeredwindowattributes
2. run Kirill's demo and make the window semitransparent
3. right click the edit control
4. move the mouse pointer across the shortcut menu boarder(and select the topmost item - Undo(U))
5. you'll see what happens to the selected part of the menu
------------------------------------
Anyone know why this happens and how to correct it? 
Thanks

hi!,
does anyone a sample code of File system api hook for win9x and win nt/2k.
for win9x we need to write a vxd and for win nt/2k we should write a file system driver.
i need to hook the createfile(),writefile() etc.. calls.
thanks

The mechanisms are completely different for the 16/32-bit shells (9x, ME) than for NT kernel based OSes.
But if you only need to hook Win32 API calls, it'd be much, much, easier to use "injection" and IAT patching. I believe there are examples of this at this site. If not, try codeguru or google and you'll find how to do it.

ya i have read about injecting using IAT,its also called api hijacking,i got the article on this site itself.
as you said those are completely different mechanisms for doing the things in win9x/me and ntbased system.
we have to write a vxd for win9x/me and filesystem driver for ntbased systems.
i wanted to do things using these mechanisms.
if u can recommend any good books for the same then it would be helpful.
thank you

OK, that concludes it. You *are* stuck between a rock and a hard place. You will have to learn Win9x VxD programming. You will have to learn NT kernel mode programming. You will have to learn filesystem filter drivers, the subtle but often crashing (BSOD-style) difference in the driver model between e.g. NT4 and NT5, the addition of IRP_Xxxx "messages", the addition of ... if you are unlucky even the added power management in NT5+. Just to mention a few of the problems you are facing.
I wish you luck. This is an effort I'd myself feel as a refreshing challenge to undertake! 
If I knew less than I do, I'd really recommend the (AFAIK) only commercial entity that *do* know these things and can provide both help and education: OSR. Please note I know close to nothing about that company and have no interests in it - it just happens to be the only entity I know about that actually *can* provide help in these areas.
Again: ++luck;

hi ,
am trying to Draw a rect on top of the text. It is not working . pls see the code
CFont font;
CSize sz;
CBrush gBrush = RGB(10,255,10);
CBrush bBrush = RGB(0,0,0);
CString str=_T("HELLO WORLD");
VERIFY(font.CreateFont(
25, // nHeight
0, // nWidth
0, // nEscapement
0, // nOrientation
FW_NORMAL, // nWeight
FALSE, // bItalic
FALSE, // bUnderline
0, // cStrikeOut
ANSI_CHARSET, // nCharSet
OUT_DEFAULT_PRECIS, // nOutPrecision
CLIP_DEFAULT_PRECIS, // nClipPrecision
DEFAULT_QUALITY, // nQuality
DEFAULT_PITCH | FF_SWISS, // nPitchAndFamily
"Arial Narrow")); // lpszFacename
pDC ->SelectObject(font);
pDC->SelectObject(bBrush);
pDC->TextOut(5, 5, str);
pDC->SelectObject(gBrush);
sz = pDC->GetTextExtent(str);
pDC->Rectangle(5,5,sz.cx+5,sz.cy+5);

CDC::Rectangle() uses the current pen, not a brush. Create a new pen first, select it into the DC, and then try drawing it.

hi Thanks for the reply...I tried that way also, pls see the code, but not working.
Thanks very much
CFont font,font2;
CSize sz;
int x1=0,y1=0,x2=0,y2=0;
CString str=_T("HELLO WORLD");
VERIFY(font.CreateFont(
25, // nHeight
0, // nWidth
0, // nEscapement
0, // nOrientation
FW_NORMAL, // nWeight
FALSE, // bItalic
FALSE, // bUnderline
0, // cStrikeOut
ANSI_CHARSET, // nCharSet
OUT_DEFAULT_PRECIS, // nOutPrecision
CLIP_DEFAULT_PRECIS, // nClipPrecision
DEFAULT_QUALITY, // nQuality
DEFAULT_PITCH | FF_SWISS, // nPitchAndFamily
"Arial Narrow")); // lpszFacename
pDC ->SelectObject(font);
sz = pDC->GetTextExtent(str);
CPen myPen(PS_SOLID,1,RGB(10,255,10));
pDC->SelectObject(&myPen);
pDC->TextOut(5, 5, str);
pDC->Rectangle(5,5,sz.cx+5,sz.cy+5);

1) What is the value of sz? Is it returning a valid size?
2) What is Rectangle() returning? It should return TRUE if successful.

actually, CDC::Rectangle() does use the current brush for filling the rectangle. It uses the current pen only to draw the rectangle's edges.

I copied your code into my app, and it worked perfectly. It drew a green rectangle over the text.

fo me only a green rect is coming
but no text
rect and all giving me return value success
|
|

That is because the rectangle is over the text;) (ie. The text is behind the rectangle) If you shift the rectangle over a little, you will see the text behind it.

Hi, all
I am trying to write a high performance library by using inline assembler, but I have encountered a irritating problem. It seems that VC++ refuses to accept multi-instructions within the inline asm section for the macro. For example, I can write a inline assembler macro with the single instruction “mov eax, 0” but that’s it, VC++ refuses to accept anymore instructions. The following code might give a better understanding.
#define TestMacro1(x) _asm{ mov eax, 0 } // This works<br />
#define TestMacro2(x) _asm{ mov eax, 0; mov ebx, 0 } // This doesn’t
So what I am trying to do here is to add more then one instruction into the macro, but I don’t know how. Any ideas on how to solve this are highly appreciated.
Thanks in advance.

My untested guess would be
#define TestMacro2(x) _asm{ mov eax, 0 \
mov ebx, 0 }
// Afterall, I realized that even my comment lines have bugs

When I try to compile this:
#define TestMacro2(x) _asm{ mov eax, 0 \
mov ebx, 0 }
int main() {
TestMacro2(0);
return 0;
}
I get the following error and warning with VC++:
warning C4405: 'mov' : identifier is reserved word<br />
error C2400: inline assembler syntax error in 'second operand'; found 'register'
Thanks anyway

I am sorry Aidman that it didn't work. It was just a suggestion that I didn't test, because I was in a hurry.

Nope. Won't work. The '\' at the end of the line will cause the two lines to be concatenated, effectively becoming
#define TestMacro2(x) _asm{ mov eax, 0 mov ebx, 0 }You'll have to use PJ's solution to get the result he's after.

It was a shot in the dark. In assembly there are no line delimiters such as ; (I am sure you know this), while PJ's solution seemed to work I thought he could give it a try with my idea. Obviously, it doesn't work.

The __asm is its own separator, so __asm mov ax,0 __asm mov bx,0 is perfectly valid code.

Hi,
Did you try:
#define TestMacro2(x) { _asm mov eax, 0 _asm mov ebx, 0 }
or even
#define TestMacro2(x) { \
_asm mov eax, 0 \
_asm mov ebx, 0 \
}
Both of the above should work - note the surrounding braces {} are not necessary but are there to make the code look prettier.
