How can I trap all windows messages - not only the ones sent to my application but all messages in the system?

You will have to deal with the messages using Hooks.
It's a suggestion that hooks should only be used if necessary.

Check Here to get sample of message hooking.

try to set SystemWide hook with SetWindowsHookEx with WH_CBT as parameter

Dear developers,
I am a Visual C++ developer and facing heat & difficulties from VC++.Net. It has changed the whole structure. With the introduction of Classes in .Net, programming in Vc++.net is very different from Vc++ And I find it hard to migrate to VC++.Net. Moreover, There are hardly any newsgroups favoring VC++.Net. Tell me Is It an end to VC++ future? Will VC# be our next programming language?
To me .Net appears equal to Java with the class concepts.
Kindly explain a simple example like adding two integers in VC++.Net.

You can also use the existing C++ syntax for adding 2 integers.

in a console based application the code goes like this
int i=10;<br />
int j=20; <br />
int k=i+j;<br />
Console ::WriteLine (k.ToString());<br />
and yes as far as the answer to your second question is concerned let me make it clear with thousands of developers working on VC++ it's not going anywhere right now. It would take a long time to make applications without VC++ for half of the world

Thank you! but I am unaware of the programming pattern in VC++.Net or else is it the same as in VC++
//Taking simple interger addition function as an example
#include....
void main(void)
{
int i=10,j=20,k;
k=add(i,j);
Console::WriteLine (k.ToString());
}
int add(int a, int b)
{
return (a+b);
}
Please also tell me that to which header file does this ToString() function belong?
Thanks Once again
Gagan..

There are classes belonging to the System namespace.
Ex:
Int32 belongs to System namespace and ToString is the overriden function in that class.
The programming technique is a bit different when it comes to using .NET .

Hello,
I have to replace the occurances (which is near about 700) of a macro say ASSERT with its extended functionality say EXT_ASSERT. I can do in the following ways:
1. #define ASSERT EXT_ASSERT - but in this case if anyone want to use ASSERT he can not use it.
2. replace all the 700 occurances - replacing like this is difficult and more error prone.
Can any one tell me the better way of doing this.
Thanks and regards,
Ritesh S.

what do you mean anyone ??
ASSERT is works in DEBUG mode only.

Hello! Mr. Ritesh
This question is quite interesting. I also even tried typedef but failed. But you can create a small string-based program that can read the whole file and will replace the string ASSERT with the specified word "EXT_ASSERT" simultaneously. I know its a lengthy and time-consuming procedure.
I hope there would be another way to solve this problem.

Replacing in multiple files is less difficult if you use Edit --> Find and Replace --> Replace in Files command and specify Match case and Match whole word options.

If your dlg1 is also Modeless then check how you showed the dialog which may restricts your dlg2 to come at front.

are you setting the style of the dialog as child.

This may be the wrong way to do it, but you could set the parent for the second dialog to the Desktop window like GetDesktopWindow().
this is this.

Use:
HWND GetActiveWindow(VOID);
and then use BringWindowToTop() function

Nish has a good work around for this problem. this one i have taken from voidnish.com
He says:
How to steal focus on 2K/XP
I bet that sometimes you long for the old days when a simple SetForegroundWindow brought your dialog into focus. Sigh! Now with 2K/XP things have sorta changed so that if you try a simple SetForegroundWindow you end up flashing the taskbar icon a few times (I never counted but something tells me it flashes thrice). Not exactly what you wanted to do, eh? Luckily there are ways to bring your dialog into the foreground.
The trick is to use AttachThreadInput to attach the thread that owns the current foreground window to our thread, then call SetForegroundWindow and then detach the attached thread, again using AttachThreadInput. Cool, huh?
AttachThreadInput(
GetWindowThreadProcessId(
::GetForegroundWindow(),NULL),
GetCurrentThreadId(),TRUE);
SetForegroundWindow();
SetFocus();
AttachThreadInput(
GetWindowThreadProcessId(
::GetForegroundWindow(),NULL),
GetCurrentThreadId(),FALSE);

Hi,
I have used Splitter window and did a (1 row,2 cols ) split and Created Views for the Corresponding two panes. The View in the left pane has tree control in it and in the right pane has form view.
If I Click on the Items in the left pane I don't have any problem but if I
click the view in right pane and again click the left pane I am getting an exception.
CCreateContext context;
context.m_pCurrentFrame = NULL;
context.m_pCurrentDoc = GetActiveDocument();
//Getting an Exception in the above Line
context.m_pNewViewClass = NULL;
context.m_pNewDocTemplate = NULL ;
Any suggestions Please
Thanx in advance
