I have a function that responds to a message by incrementing a counter variable by 1:
OnAction(WPARAM wParam, LPARAM lParam)<br />
{<br />
m_nCounter += 1;<br />
}
The message that it responds to is posted twice using PostMessage, once immediately after the other (like so):
::PostMessage(GetSafeHwnd(),WM_ACTION,0,0);<br />
::PostMessage(GetSafeHwnd(),WM_ACTION,0,0);<br />
The strange thing is that if i modify the function to display a MessageBox with the value of the counter (like so):
OnAction(WPARAM wParam, LPARAM lParam)<br />
{<br />
CString string;<br />
m_nCounter += 1;<br />
string.Format("%d",m_nCounter);<br />
MessageBox(string);<br />
}
I get two message boxes, as I should; however the values in the message boxes are 2 then 1, not 1 then 2.
Howcome I am receiving 2 then 1, rather than 1 then 2 from the message boxes as you would expect?
Any help would be greatly appreciated.
Thanks

both the message box comes on together?
as far as i know, message boxes in certain events could be very tough way of debuging the app coz the message boxes starts pumping the messages, so other messages too gets executed.
try TRACE instead.

::SendMessage(GetSafeHwnd(),WM_ACTION,0,0);
::SendMessage(GetSafeHwnd(),WM_ACTION,0,0);

if you want to get the result as you say,you should write like these.
when we use postmessage to send the message,the application
only send the message to CWnd,then return,the application does not
wait for the Command to be carried out.
when we use sendmessage to send the message,the appliation return
when the command be carried out.If we does not wait for the command
to be carried out.The message will be save in the message queue,
so the message is FILO,not FIFO

I want to write something like the Sub7 Configure program, where it overwrites some of the values already in the seperate exe.
I've tried changing some of the constant data in the program and saving it but it doesn't work. I think it's because I need to change some of the info in the EXE header.
My problem is that I downloaded a EXE Header info checker and checked a program I made, them I changed some stuff in that program and checked it again and it was all the same!
Any ideas on how I can change what's already in the exe?
P.S. I don't want to use String Table Resources either.

how do you split an integer variable into 4 byte variables, I'm looking for a function to achieve this.
int i;<br />
byte b1,b2,b3,b4;<br />
<br />
b1 = Byte1(i);<br />
b2 = Byte2(i);<br />
b3 = Byte3(i);<br />
b4 = Byte4(i);
Can anyone help?
Thanks

Many way to do this.
One brute force way is:
b1 = i & 0x000000ff;
b2 = (i & 0x0000ff00) >> 8;
b3 = (i & 0x00ff0000) >> 16;
b3 = (i & 0xff000000) >> 24;

not a very safe-cast method but who cares it works:
<br />
int i = 12345;<br />
unsigned char byte1 = ((unsigned char*)&i)[0];<br />
unsigned char byte2 = ((unsigned char*)&i)[1];<br />
unsigned char byte3 = ((unsigned char*)&i)[2];<br />
unsigned char byte4 = ((unsigned char*)&i)[3];<br />

I will add this one:
int i=12345;
BYTE* ab = (BYTE*)&i;
// use ab[0-3]

assume i is 2 bytes for simplicity.
int i = 0x1234;
byte c1,c2,
then according to your logic, the output would be like this.
c1 = 0x34; and
c2 = 0x12;
which is wrong.This is because the way it is stored in the memory. and if you consider for 32bit integer value, the error would just double.
and according to PJ
c1 = 0x12; &
c2 = 0x34;
here the output is correct,
hope you got the picture now.

Where should I place my exe so that it starts running when Windows starts
|
|
|
|
|
With Windows XP:
C:\Documents and Settings\You User Name\Start Menu\Programs\Startup
Signature under construction.
|
|
|
|
|
that depends on the language windows is running...
for the french version, copy you exe into C:\Documents and Settings\"your user name"\Démarrer\Programmes\Démarrage
there should have a way to get this folder directly...

All these starts only when user logs in.
another way is to place exe path in
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
or
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
greatest thing is to do wot others think you cant

the simplest method is
under the registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
create a String type key and put full path of your exe
like c:\YourFolder\YourExe.exe

By placing my exe in the given path, its not activated when Windows starts up
|
|
|
|
|
By placing my exe in the following path(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run), the exe does not starts running automaticaly when Windows starts up
|
|
|
|
|
please once more verify the path you given in registry.
that will work..

Does anyone know of a way to discover all of the preprocessor defines that are set before and during the VC++ compilation of a module? I just want to know the results after plowing through a morass of headers. GNU CPP has such an output. Does VC++? Thanks.
