You could try not calling CallNextHookEx().
If that doesn't work, you can try installing a WH_GETMESSAGE hook and filter out the mouse messages.
The hook procedure could then not send or modify message into something like WM_NULL so that nothing is done.

populating CHAR_INFO without ReadConsole()

Quisnam1-Nov-09 21:54

Hello. Couldnt find a WinAPI / Console forum, so I guess it goes here.

I've made a console applicatione interface with two buffers, I need to write data to an inactive buffer, and then read the data to my active buffer. So far I'm writing to the second buffer with:

WriteConsole(snBuf, foo.c_str(), foo.size(), &filled, NULL);

The problem is, WriteConsole writes everything char by char, the result is fine, but its rather slow.
I would like to write with the WriteConsoleOutput() function, however, you need to put all the text in to a CHAR_INFO structure. I can't seem to be able to put more then 1 char into CHAR_INFO at a time, E.G: chiBuffer[0]->Char.AsciiChar= "A"; I would like to input a string in to chiBuffer, but it accepts just one char... So I would be forced to use a for loop, that inputs one char at a time... Is there some other way to fill a CHAR_INFO structure with a string?

Overlay Icon problem...

Hi! It's my first msg in code project!!
Here is my question.

Q. I modified overlay icon which is already registered.
But, icon has never changed.

Let me explain in specific.

I made a VC++ dll project to make overlay icon.
And, in project i draw character 'A' as overlay icon.
(I refer the article was written by lallous. - How to overlay an icon over existing shell ovjects in 3 easy steps)

Then, i registered this dll and it works beutifully!!

After few days, i neeeded to change icon. (for example, to character 'B')
So, i opened the project, and i modified icon. Then, i rebuild all.
As i did before, i registered the dll file on the system.

However...overlay icon didn't change at all...
It still has post image which i drew at first time.

I try to reboot or kill explorer and exec explorer.
or regsvr32 /u a.dll and regsvr32 a.dll
and checked registry status... but everything was fine.

I couldn't solve the problem...

Has anyone experience like me...??

plz help me... thank u for reading.

create smooth line

How can I construct the line which can adjust its amplitude?

for example, there are 7 points on a line.

I can change the amplitude by point1 to point7 through mouse directly.

thanks.

What are you talking about? Do you need to find a curve to fit data points?

if the 00:00 hour occur between two date-time variables, should the variables have different days, shouldn't them?

hi,

i have made a derived class from CDialog to customize it with my bitmaps in which some pixels need to be transparent. I am using TransparentBlt() for the same in OnEraseBkgnd() in derived class after calling CDialog::OnEraseBkgnd(). the thing is happening is those pixels are either coming grey so white sometime. not becoming transparent. Can anyone suggest where i am doing wrong !!!

without seeing the code hard to say...

hope you calls the CDialog::OnEraseBkgnd() before doing the TransparentBlt().
