BOOL GetVersionEx(LPOSVERSIONINFO lpVersionInfo);
Declared in winbase.h, include windows.h to get it. MSDN has information on the OSVERSIONINFO struct (see below).
GetVersionEx[^]
Hope this helps.

I am unable to synchronize the threads(simultaneous) greater when they are greater than 100. The thread increments a global Unsigned Long the requested num of times.
The code is....
// [5/4/2004] AS told by Marshall Brain.....
// thread 3
// very simple MULTI threaded prg...with CRITICAL SECTION synch'n method
// Prob ?? : Results are RANDOM ??
#include<windows.h>
#include<iostream.h>
volatile ULONG g_count = 0; // volatile so that compiler doesn't do any optimizations (like place it in a register)
// and we are able to alter the var. inside the thread also
const INT NoOfThreads = 10;
CRITICAL_SECTION CritSec;
void CountThread(INT Iterations)
{
INT i;
// UINT x;
Sleep(5000);
for( i=0; i
|
|
|
|
|
Not sure about this for loop?
for( i=0; i
{
// EnterCriticalSection (&CritSec);
// x = g_count;
//x++;
g_count++;
// LeaveCriticalSection (&CritSec);
}
But here, try this.
Static CRITICAL_SECTION CritSec;
For (i= 0; x < something; ++x)
{
x = g_count;
x++;
EnterCriticalSection (&CritSec);
g_count++; // This is global to all threads so lock this only.
LeaveCriticalSection (&CritSec);
}
So yes, you are right the answer would be random. If you don’t want random then do this.
Static CRITICAL_SECTION CritSec;
// This is global to all threads so lock the whole loop.
EnterCriticalSection (&CritSec);
For (i= 0; x < something; ++x)
{
x = g_count;
x++;
g_count++;
}
LeaveCriticalSection (&CritSec);

Hi there,
I was wondering if it is at all possible to change the tab order of controls (with WS_TABSTOP style) at run-time.
As far as I could find out up to now, only the order in which the controls are created define the tab-order, I got the problem now however that I derive a dialog from an existing one, the new one has a few extra controls which should appear between controls of the base-class dialog. The controls of the base class are created first and then the new controls which results in wrong tab-order in the dialog.
Any help would be greatly appreciated
Regards,
Davy

Try SetWindowPos() and change the Z-Order relative to another control.

From MSDN:
To change the tab order at run time you would need to call the SetWindowPos API. Microsoft Windows maintains all the windows in the system in a list. It uses this list for purposes like painting the windows, maintaining the z order, and so on. The order in which the child controls (in a dialog) are created determines their position in the list and, hence, the tabbing order. By changing the position of the windows in this list, we can change the tabbing order. Change the window list order by calling SetWindowPos and passing the relevant windows handles in the first parameter (handle of the window to insert in order) and the second parameter (handle of the window to insert after). The window handle specified in the first parameter would come after the second in the tab order.

Thanks,
Always thought that a lot of questions in this forum could be left out if the questioner just went to the trouble of searching in MSDN lib for 2 minutes. Seems I am guilty of the same crime.
Thanks anyway,

 Dear Mr Bhavani;
Thank you for the help that you have given me in accessing a public variable from anywhere within my application. The problem is that the code did not work at all. The compiler strongly complained when i added these code:
((CDatastructorView *) AfxGetMainWnd())->m_main.Navigate"file://c:/datastructor/lectures/recursion_implementation.htm",0,0,0,0);
CDatastructorView is my view class and m_main is a web-control which i want to use.
The compiler responded as :
:\datastructor\lefttooldlg.cpp(1296) : error C2065: 'CDatastructorView' : undeclared identifier
C:\datastructor\lefttooldlg.cpp(1296) : error C2059: syntax error : ')'
C:\datastructor\lefttooldlg.cpp(1296) : error C2059: syntax error : ')'
Could you please help me out because i am still pretty at lost.

In what file did you define the user type CDatastructorView?? Just include that .h file in the lefttooldlg.cpp.
Maxwell Chen

|
|
|
at the top of lefttooldlg.cpp add
#include "..." //... = header file where CDatastructorView is defined
and your call should be:
((CDatastructorView *) AfxGetMainWnd())->m_main.Navigate("file://c:/datastructor/lectures/recursion_implementation.htm",0,0,0,0);

I need a CListCtrl derived class using owner-drawn report-mode but with '1 virtual column' that always stretches the entire viewable area.
Any ideas ?
|
|
|
|
|
then you would have to draw the columnd AFAIK...it would make your a job a lot easier to use custom draw though...
Cheers 
How do I print my voice mail?

I'm ok with that, I already have a full-fledged Owner-Drawn CListCtrl.
My only problem is that in a certain configuration I'd like to move to a 'non column-based' layout and maintain my owner-drawn capabilities, this doesn't seem to be supported in a standard manner.

|
|
you could use InsertColumn only once and setting up the width of the control, it should use all the control's width and only in one column.

Hi to everyone reading this...
I have noticed that when an EditBox has the option singleline then if u add a notification handling function to it (lets say for the event EN_UPDATE ) and u call SetWindowText inside the function u instantly u receive a second notificatio and again and again.....
If though the EditBox has the option multiline the above behavior does not take place. Insted the notification arrives only once, SetWindowText sets the new text to the EditBox and the notification handling function exits.
Does anybody know why this deference exists? Does it serve a purpose?
In a single line EditBox how can i alter the text typed before it is displayed?
Thanks in advance for helping....

Just curious, but when you set the text for a single line control, how many r\n\ were there?
How do I print my voice mail?
|
|
|
|
|
Well the text i'm printing with SetWindowText is just one single line thus the editbox doesn't contain any \r\n characters.
What do u mean "How do I print my voice mail?".

Hi all,
I was wondering if someone can shed some insight into this problem i'm having. I am decent with C++ but very new to managed C++.
I have a managed c++ class library which wraps some unmanaged c++ code. At the moment i'm using a test harness which is a C++.NET Windows Forms Application project. (I have also tried writing the Test harness in VB.NET and C# but got the same error).
What happens is that when i start up the test harness, the form loads, but when i click the button to run the function i am testing from the class library, i get the error i have pasted below.
I have tried explicitly defining the path of the class library's output directory using the Reference Path project property, and have also tried copying the project output manually into the test harness' executable dir. ANd now i'm not sure what else to try!
Thanks in advance for any help/info..

The error output is below:
----

I am using VS-6.0 & C; Win-2000. I want to use the function SetDCBrushColor but when I compile the code I'm told this is an undeclared identifier. MSDN says that this is declared in Wingdi.h (use Windows.h) and is in GDI32.lib -- even though I am doing this (started with Windows.h already, and have tried adding Wingdi.h; GDI32.lib is in my project settings) I'm still not having luck. Any advice?
(this has happened on two machines, one set up at work and one I did at home ; if I open Wingdi.h I can see the function declared...but apparently my project does not?)

You need to have the _WIN32_WINNT macro defined as 0x500 or higher in order to use that function. The best place to do that is in your stdafx.h file.
#define _WIN32_WINNT 0x500

Hi,
I am totally new to creating dlls . I've one doubt to be solved urgently --
For Windows -
There is a application which loads a dll, calls the dll's entry points and puts some data into the dll's data structures. Now there is another application which again loads the same dll and calls the dlls' entry point.
Is it possible to do the above in VC++. I am not aware so I may have put some terms very wrong. Pls correct me for that..
Any response greatly appreciated...
Regards
