Hmmm...
Does the second bit of code take 'spouse' as an example to make
'newpersonname' or does it erase 'spouse' in order to replace it
with 'newprersonname'?

Thanks anyways!

Does kernel driver can invoke GetLogicalDriveStrings()?

GetLogicalDriveStrings() can be used to get system driver stirngs in user mode app,if it can be used in driver program to do the same thing?
Thanks!

changing brush attributes at runtime

In my application i need to change brush attributes e.g color etc at run time,

consider following

CBrush b1;
b1.createSolidBrush(RGB(255,0,0));

now how can i change the color of same brushto green color?

An alternate option is to create new brush when it is needed and then destroy when its not, but this creation/destruction will slow down the prog, thats why i want to use only one brush and change its attributes as needed at run time

Thanks in advance Rose | [Rose]

or create them both at the start of your app, and destroy them both at the end

If there were only two brushes needed then I would do the same but in my case i can't tell how much brushes will be needed, eg 1000.

in above case the best option is to create on eand change its attributes at run time.

except that it's probably not possible to do that.

As far as I'm aware you don't - You create a new one.

Are you sure that creating/destroying the brush each time is that expensive? Try it and see how the program performs.

Mouse hook

Hi guys,

Can any one suggest me how i can write a very simple mouse hook?
suggest me some sample code.

Thanks,

Ram..

use SetWindowHookEx as follows

SetWindowsHookEx( WH_MOUSE, MouseProc,0,0);

u should write a function write a function(here "MouseProc") with prototype

LRESULT CALLBACK MouseProc( int nCode,
WPARAM wParam,
LPARAM lParam
);

Now u will get all the mouse messages in the function "MouseProc".

The above hook only works inside ur application scope. For u to make the hook globel u should have to write the "MouseProc" in a dll. and pass the instance(obtained from LoadLibrary) as the third parameter to the SetWindowsHookEx function.

Hi Naveen,

Thanks..
As us said i am looking for a global mouse hook.
are there any rules for the dll like it should be a com outproc server or
is it enough to be ordinaly dll.

thanks and regards,
Ram

How to do complex window UI?

if use dialog, it is easy,because vc supply a dialog editor, you can design your UI very intuitionistic.

but for a complex UI for example vc6(not complex as that ,just a example)

how to do? Must I calculate the coordinate of control(position ,size etc...) by hard code?
