LVIS_SELECTED (SetItemState()) should be the message you want to use.
state, stateMask LVIS_SELECTED | LVIS_FOCUSED
You may need to remove the slected/focused state from the previously selected item(s)...
LVM_GETNEXTITEM (GetFirstSelectedItemPosition()/GetNextSelectedItem()) will help find those.

Hello,
If I have vector of int and vector of strings
vector<int>IntVector
vector<string>StringVector
and now I want to compare an int a within IntVector
and string s within StringVector
which comparison or search within these vectors will take more time.
I expect the size of vectors to be 100000.
so will it make a significant difference.

Why don't you implement both and time them, then tell us?

Without actually testing it myself, I'd say comparing strings would be slower.

Hello,
Thanks
Even I thought strings would take more time.

Hi,
Why don't you try to compare ASCII code? It can be the easiest way, as long numbers and letters are there and are different, and you can use higher than, lower than, equal... as well.

Hi, in my application I'm setting the fonts of some controls through WM_SETFONT by creating a LOGFONT and then calling CreateFontIndirect to create an HFONT from the LOGFONT.
For some reason the fonts don't look the same in debug and release mode. Also they look different on different computers. Is there a better way I can set the fonts, a more "standard" way that would look the same on all systems/modes?
For instance I wish I could just say, make the font 10 point FixedSys font. But with LOGFONT I have to give it lfHeight and lfWidth which seems somewhat arbitrary.
Thanks for help!

Probably not much help, but...
I get consistent results across machines by setting only the lfHeight, lfWeight,
lfPitchAndFamily, and lfFaceName members of the LOGFONT struct. The rest of the members are set
to 0. I use a negative height and let the system pick the appropriate width.
The only inconsistency I've experienced is when using a specific font that does not come pre-
installed on all systems (so the font gets mapped to the closest match, not always good).

I didn't realize I could use negative height to have the system auto-set width; this seems to make everything work correctly in my program. Thanks much!!

Use (or lookup the implementation of) CFont::CreatePointFont(...) - it is great for creating fonts of specific point sizes. For example:
CFont fMyFont;
fMyFont.CreatePointFont( 100, _T( "FixedSys" ) );
Peace!

File I/O is file I/O regardless of what you put into the file. Do you know how to write to, and read from, a file?

If you are using C++, then I would suggest file I/O from the STL. See here and here.

we've got a dialog window and are using the Power point object model to run the slide show. We've set that power point slideshow window into the main dialog window's client area by using SetWinodwPos(). The slide show runs properly, the problem is that if we click Deskop button (Show desktop) on quick launch toolbar it gives some painting issues. The slideshow window set into client area of dialog doesn't paint itself clearly. What should we do to overcome these painting issues ? Do we need to handle EraseBkground or WM_PAINT of dialog window ? what should be our move in this case ?

Hai All,
I have a doubt regarding the transfer of Data in InterProcess
communication like Socket Programming.
->Client and Server are two different Process running in two different
machines
->Assume , I am passing a user defined structure from client process to
Server Process.
->As usual I will fill the structure with values and pass the address
of structure to the server process.
->My doubt starts here , since Server is another process running in
another address space and also in another machine, how can the
server fetch the values stored in the address given by client.
Are they sharing any memory ??, if yes, where it resides ??,
Thanks
George

When you pass a "pointer" to be sent over a communication link (it can be serial port also), you supply also a size. So, what the send function is simply doing is copying X (the size you supplied) bytes starting at the address you supplied (the pointer). So, there is no magic there (or no shared memory or whatever). But, of course you have to take care that what you send is a pure data block (so, if there are pointers in your structure, the address will be sent, with no possibility to extract the data at the other side).

 What? It's not passing the pointer itself. We just tell the API function from where it should take the structure. We are pointing addresses to the function and NOT!! to the machine that's on the other end!

How to Place a menu in th bottom in a dialog based application
Thanks In Advance

Hi,
From MSDN:
CMenu::DrawItem
This member function is called by the framework when a visual aspect of an owner-drawn menu changes.
Syntax
virtual void DrawItem( LPDRAWITEMSTRUCT lpDrawItemStruct );
Maybe Position has something to do with this too.
