The above code creates an instance of a dialog box, but does not initialise it. You can't show or hide a window that has not been created.

There's an article on CP describing how to DoModal() on a dialog and have it hide immediately.

I don't know if Jon was referring to this post of mine, but anyway there you'll find how to have your dialog hidden on startup.

Why would you want to? compilation of file order is irrelevant!?!

The order maybe bases on your head files' order.;P

Hello,
I have a MDI app. and in the status bar I have a progress control.. The problem I am having is when ever a long function is taking place my app freezes until the function is finished (because of the progress control). If I remove the progress control everything is fast and smooth.. How can I create a progress control in the status bar with out killing my application performance? Here is a sample of the code I use to create the progress control.
void CMainFrame::DownloadProgress(long nProgress, long nProgressMax)
{
RECT MyRect;
m_wndStatusBar.GetItemRect(1, &MyRect);
if (m_bCreate == FALSE)
{
m_Progress.Create(PBS_SMOOTH | WS_VISIBLE | WS_CHILD
, MyRect, &m_wndStatusBar , 1);
m_Progress.SetRange(nProgress,nProgressMax);
m_Progress.SetStep(1);
m_bCreate = TRUE;
}
for (int i = nProgress; i < nProgressMax; i++)
{
m_Progress.StepIt();
}
}
Any pointers?
Thanks,
Rob

It sounds like you're doing everything in one thread, no? If so, read the VC forum FAQ (link at the top of the page) that addresses your question.

You were correct, I am in a single thread.. Thanks for the post, everything works great.

Could anyone help me with the following expressions?
n5-=7+2/3*10
and also
f2=10.0-18.0/-3.0*2.5e-1

Did you try writing a small program to see what results you would get?

ok. saying "n5 -=" is equivalent to saying "n5=n5-". the rest of it is down to operator precedence. see "operator presecence" in MSDN.
but, you can make that expression clearer by writing it like this:
n5=n5- 7 + (2 / (3 *10)) ;
why? because in VC++, / has higher precedence that +
the second expression:
f2= 10.0 - (18.0 / (-3.0 * 2.5e-1));
In both cases, i suspect you're getting a different answer than you intended, due to operator precedence. It's good practise to always specify precedence with ()'s.

This is wrong. It evaluates as I said in the lounge - 2 gets divided by 3 and the result multiplied by 10, so that part comes to zero ( because 2 and 3 are not floats ), but if it gets made 2.0 and 3.0, you get 6.666(10 * .66666), not 0.0666 (2/30). / and * have equal precedence, left to right.
So the correct way to use brackets to show order of operation is
7 + ((2/3)*10)
and the 2 and 3 should be floats in order to get an answer other than 7.
Also, are you recommending not using -= here, or am I misreading you ?
Jon Hulatt wrote:
f2= 10.0 - (18.0 / (-3.0 * 2.5e-1));
Again, this is wrong - put it into a console application and see for yourself. The result is 11.5, not 34 as your bracketing would evaluate to.

That'll teach me to read the doc's more carefully. I forgot that * and / had equal precedence, in left-to-right order.
I wasn't recommending not using -= at all. from the guys original post it wasn't clear exactly what he was having trouble with.
Anyway, my incorrect answer to the question highlights why it's a good idea to always enforce your own precedence using ()'s. Especially if you use different languages frequently where precedence varies.

Absolutely - I use a lot of brackets especially in the case mentioned, where a multiply happens after a divide. It's always better to have brackets show what you assume will happen, just in case your assumption is wrong.

Geoffrey, while this question is probably better off here than in the lounge, it was general enough that I answered it there. Either way, please don't ask the same questions over and over, once here is enough.

What is the best way to download a file with http protocol and actually test to see if that file really does exist? I have looked and looked to no avail. Any help will be greatly appreciated.

lol Why is it always the obvious things we overlook?
I used OpenURL() but no real way of checking if it exist or not; Unless I make it a complicated task.
Thanks Mike

Can some one tell me what the problems is...?
LPCTSTR GetBuffer()
{
LPSTR buff = "";
CopyMemory(buff, GlobalLock(m_hBuffer), m_nSize);
GlobalUnlock(m_hBuffer);
return buff;
}
CopyMemory fails!!! I've managed to use similar code for the SetBuffer function.
CopyMemory(GlobalLock(m_hBuffer), buff, m_nSize);
Why does the one work and not the other...?
TIA

I've fixed the problem, but i dunno if it's a proper fix.
LPCTSTR buff = (LPCTSTR)GlobalLock(m_hBuffer);
GlobalUnlock(m_hBuffer);
return buff;
I'm assuming the prob was that the temp buff is destroyed when outta scope...? So the CopyMemory had no effect. ultimately all i wanted returned was an address to the buffer and the above does this. However Locking the handle returns a pointer, doesn't Unlocking invalidate the handle...?
The above code works, but isn't it set up for failure, i'm kinda lost as to why it does work...? Each Lock increments a counter kinda like COM objects right..? as the Unlock does the opposite, as long as the lock count is zero shouldn't it fail...?
Thanx again!

How can I put a array that represents an image on my window. Have I to create a DC or something? Name of functions and explanations would be very nice.
