I tried to use OnCreate, but at use SubclassDlgItem() I do not get in OnCreate.
Therefore I have decided to create scroll bar in a PreSubclassWindow () method.
But there is one problem!!! I do not know exact height and a position scrollbar yet I shall not start draws the control in OnPaint. How to be in this case?

Ahh, that makes it more clear. Because you are sub-classing the item, this happens in a dialog OnInitDialog function. I would write a public function as part of the class to create the scrollbar. Something like this:
bool CMyEdit::CreateScrollBar()
{
CRect rect ;
GetClientRect(&rect) ;
if (!m_ScrollBar.Create(WS_CHILD | WS_VISIBLE | SBS_HORZ, rect, this, 1))
{
TRACE("Failed to create scroll bar\n") ;
return false ;
}
return true ;
}
You would then call this in the OnINitDialog after the control has been sub-classed.

Thank for the help!!!
Now I create CScrollBar<code> in <code>PreSubclassWindow()
pVScroll.Create(WS_CHILD | WS_VISIBLE | SBS_VERT | SBS_RIGHTALIGN, CRect (0, 0, 100, 100), this, 100);
And then in function OnPaint() when becomes the sizes scrollbar are known, I do the following
pVScroll.MoveWindow(rect);
As far as I do correctly all?

It's better to move (resize) the scrollbar when your edit control gets a WM_SIZE, not WM_PAINT. A WM_PAINT handler should be as fast as possible.

What king of control do you want? There are lots of sample in codeproject.

Newbie Question!
I need the integer value in a 'command line char array' to increment with the for loop.
eg
On the first loop the cmdline[]="C:\\myexecutable --getmemory SM 1";
On the second loop the cmdline[]="C:\\myexecutable --getmemory SM 2";
On the third loop the cmdline[]="C:\\myexecutable --getmemory SM 3";
etc, for 10 loops.
I have tried the following
for(int i =1; i<=10; i++)
{
char strInitial[] = "C:\\myexecutable --getmemory SM ";
char cmdline[]=("%s [i]", strInitial);
...//snip
}
But I get the following error:
error C2440: 'initializing' : cannot convert from 'char *' to 'char []'
Or if I remove the ()'s
for(int i =1; i<=10; i++)
{
char strInitial[] = "C:\\myexecutable --getmemory SM ";
char cmdline[]="%s [i]", strInitial;
...//snip
}
Then I get the following error:
error C2040: 'strInitial' : 'char' differs in levels of indirection from 'char [49]'
Please help!
Thanks.

Try this
char szBuffer [256];
sprintf (szBuffer, "C:\\myexecutable --getmemory SM %i", i);

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

how could i make a window transparent for win32 not MFC 
ta, any help will be greatful.

You can set the WS_EX_TRANSPARENT ex_style, but this will only work for Windows2000 and above. You can also use SetWindowRgn to make your window appear that it has holes in it.

You may find a wonderful article from MAK Jeelani about transparent windows at:
http://www.codeproject.com/csharp/transparentwindowsincsharp.asp
It's in C# but if you writing MC++ is easy to follow!
Otherwise try this article from Franz Brunner:

Hope this helps

For the Successfull conection with the ODBC
You must
1)Create a CDatabase object
2)Connect the database with the ConnectionString inm the Format DSN;Username;password
3)Create a Recordset object
4)set the m_pDatabase member to the address of the database object
5)Open the Recordset with the Query
Follow the Steps ..
Good Luck..
try it now..
any doubts..??

we have been interrupted by the class private/public/protected static variables not getting initialized before control reaches main, when those variables initialization has been placed in the other dependent libraries instead of the current project.
It seem to us that, placing all the initialization statements in some header file say 'myheader.h' and adding this header to the main project, is better solution at the moment.
But, this activity is consuming large amount of time.
Can anyone inform us if we can initialize the class static variables in the other dependent libraries using other better way?
We know the following.
1) All global data including global static variables must be initialized before control reaches main function.
2) All local static variables will be initialized when the control calls the respective function for the first time.
What about class static variable? They have class scope. But they have program life time. Therefore, we guess our program is not proceeding further just because the class static variables in other dependent libraries are not getting initialized?
Is our assuption correct?
Any help in this regard would be highly appreciated.
Thanks in advance,
-Sarma
