What both I and Michael Dunn suggested is a common technique used when something has to be done when all dialog controls has been created and initialized. I thought this was your problem since it's quite common.
The last message handled when a dialog is created is usually WM_PAINT. Both WM_SIZE and WM_SHOWWINDOW are sent prior to WM_PAINT.
If it's imperative that your dialog is visible to the user there is no message handler you can override. You have to write code inside the message handler for WM_PAINT, OnPaint().
Like this:
void CShowDlg::OnPaint()
{
static BOOL bShown = FALSE;
if (IsIconic())
{
CPaintDC dc(this);
SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
dc.DrawIcon(x, y, m_hIcon);
}
else
{
CDialog::OnPaint();
}
if( !bShown )
{
bShown = TRUE;
}
}
Sorry that I misunderstood your needs. :->
I just haven't encountered a initialization situation yet that actually requires the dialog to be visible and I can't figure out why this would be necessary. It's not necessarily wrong, I'm just curious.

Hello, that's still not quite what i want, maybe i'm going about it all wrong.
The dialog box has a text box inside, and i would like this to display text strings about the status of the program to the user. The whole process needs to be launched by pressing a button, which launches the form, and only then once the form and controls are visible can the program's main function begin as otherwise any realtime messages to the controls won't be visible. I know i could probably do this more efficiently using another thread but i thought it would be much more complex and error prone.
Is there a better way of doing this?
Thanks a lot for all your help btw.

Any suggestions?
Thanks

I don't think my query(on C) is directly related to this board..however i post it here cos of urgency...
I wrote:
--------------------------
#include<stdio.h>
void fun(int** x)
{
printf("%d",**x);
}
int main(void)
{
int a[2][2]={1,2,3,4};
fun(a);
return 0;
}
--------------------------
to get '0' as output and not '1',i.e.the 1st element in the array.
I ran this on TC 2.01.
Help me if this is buggy.
Thanx!

How are you expecting to get '0' as an output. The array has four elements, none of which are '0'.

first your initializing the array incorrectly
it should be [int a[2][2] = {{1,2},{3,4}};]
??to get '0' as output and not '1' you set the first element to 1 so what
are you asking there.

In case you still need help:
I recommend reading this article which answered all my questions
on arrays in the past. Statically- and dynamically-allocated arrays
are stored differently - keep this in mind and it will help you to find
the solution to your problem.
Good luck, Sebastian

You could use ShellExecute to open the html file with the associated application, which would tpyically be the default browser.
ShellExecute(m_hWnd, "open", "my_help.html", "", "", SW_SHOW );
Is that what you're asking?
