Re: Some icons are not getting print while using mirror driver

Tech-Archive recommends: Fix windows errors by optimizing your registry

Ok, I will try it. I will let you know about it.

Try to make your driver simpler.
Can you simpply support only DrvCopyBits and DrvBitBlt
(plus the EnablePDEV/EnableSurface functions ?)

I have used WinCollab.exe and connected my two vista machines. Icons were
properly printed. No issues i found as I am getting with my driver.
My driver need something :( ... don't know what? :)
anything else you need to check?

Can you repro the issue in Vista, without a mirror driver,
with a XPDM driver at some non default color depth (like 24bpp)?

Or, if you have Vista, can you use the in-box rdpencdd.dll
mirror driver to see if it reproes. [You can use WinCollab.exe
and the releated APIs to do desktop sharing to test this].

On Windows XP all icons are painted correctly. This problem is only on
Windows Vista.
I have implemented DrvTransparentBlt and DrvAlphBlend as follows:
BOOL DrvTransparentBlt(...)
{
BOOL RetVal = TRUE;

DISPDBG((1,"Mirror Driver DrvTransparentBlt: \n"));

//RetVal = EngTransparentBlt(psoDst, psoSrc, pco, pxlo, prclDst,
prclSrc,
iTransColor, ulReserved);

if(pDrvTransparentBltObj)
{
// I have called EngAlphaBlend inside
pDrvAlphaBlendObj->DrvTransparentBlt
pDrvTransparentBltObj->DrvTransparentBlt(psoDst, psoSrc, pco, pxlo,
prclDst, prclSrc, iTransColor, ulReserved);
}
return RetVal;
}


BOOL DrvAlphaBlend(...)
{
BOOL RetVal = TRUE;

DISPDBG((1,"Mirror Driver DrvAlphaBlend: \n"));

//RetVal = EngAlphaBlend(psoDst, psoSrc, pco, pxlo, prclDst, prclSrc,
pBlendObj);

if(pDrvAlphaBlendObj)
{
// I have called EngAlphaBlend inside
pDrvAlphaBlendObj->DrvAlphaBlend
pDrvAlphaBlendObj->DrvAlphaBlend(psoDst,
psoSrc,
pco, pxlo, prclDst, prclSrc, pBlendObj);
}
return RetVal;
}

Can i do anything?

TransparentBlt is your next stop.
Certain 24bpp Icons have a custom color-key implementation
that relies on the default color of the background brush
for a Dialog to achieve the transparency effect.

Sometimes those mispaints are higher-up in the stack than your
display driver, and, they can be reproduced in TS at 24bpp,
or in older display driver at unusual color depths.

yes - our mirror driver and desktop both are at 32bit depth.
and I have hook the DrvAlphBlend function though which just puntting
the
EngAlphaBlend.

Is the mirror driver at the same color depth of the desktop ?
If your driver is at 8bpp and the desktop is at 32bpp, there might
be some down-conversion of the colors that would make layered
windows (or operation that requires AlphaBlend) to make pixel
to saturate on one side of the default palette for the device.
