How can I hide the "Printing" dialog that comes up when a report is sent off to

Hello,

I have created a MFC application (doc/view architecture) that is running in background (is not visible) and I print some reports from that application.

The problem is that the "Printing" dialog that comes up when a report is sent off to a printer is visible during the printing process.

How can I hide it?

Many thanks,
Vasile

You can probably, write your own pagination and printing
or track down the point at which dialog is being shown
in the mfc code and then override the function in your
own class and copy from the original function
and remove the dialog calling code.

Are you using a function like transparentBlt? I know there is a resource leak in this function with windows 98.

Otherwise what other types of GDI functions are you using?

No,i won't use TransparentBlt. I know there is resource leak in that function.so i had used bitblt with SRCOR,SRCAND etc...
Other types are loadimage(),creatergnindirect(),createsolidbrush()..I am deleting all the objects created.
It is fine in 2k & XP.

I don't know what is wrong?

Thanks

Any idea?

I've created a set of classes from the excel.exe (Excel 2002) type library using class wizard, and can insert my excel object in a view - all works a treat. But I'm trying to use the Worksheets::Add method and can't get it figured out, has anyone got any experience with this or could anyone let me know where I could find info about this? Confused | :confused:

TIA

Random Gaussian numbers

Dear all,

I was wondering if there is a way to generate random gaussian numbers with Visual C++.
Borland Builder has the option randg to do just this.

Many many thanks

Sorry for the typo.

The rand() just generates random numbers but not gaussian/normal distribution numbers.

Sorry, but I don't know what a gaussian number is! Frown | :(

Try go to www.msdn.microsoft.com and type in "gaussian" in the search field of "MSDN Library" and then see if you find something.

Cheers! Smile | :)

It's not a gaussian number, it's a gaussian distribution. Let's pick a simple example: if you plot people's weight x #number of people with a specific weight, you'll get a gaussian distribution: most samples will concentrate on the middle of the graphic and less people on the borders.
Gaussian distribution are also know as Normal distributions. It's know as the "bell curve" too. A picture worth more than a thousand words. See This article[^]

I've found a mathematical formula to do this now. It assume zero mean and it is written in MatLab.

sigma = 2; %The std deviation<br />
x1 = rand(1000,1); %Linear rand number between 0.0 to 1.0<br />
x2 = rand(1000,1);<br />
<br />
z = sqrt(-2*sigma*log(x1)) * cos(2*pi*x2);

the log here is ln, that is log to the base e. Now all we need is just to put it in C.

Thanks to all who replied my post.

You can use the code you listed to generate normal variates, but I believe you will get garbage out in the tails of the distribution. The random number generator that is packaged with C is not very good. I suggest you find a better one...there are plenty of them out on the web.

Here is an example

Lines not drawing right

I am trying to do a grid on a window, but it's not working right.
It is a MDI program using MFC.

When I scroll the window by clicking on the scrollbar(pagefull), it works fine
When I scroll by clicking on the scroll arrow, no new grid lines get drawn
When I scroll by dragging the scroll button, only some new grid liens get drawn
I have made the window using the CS_HREDRAW | CS_VREDRAW class style.

The window is made of 1026x1026 tiles, each tile being 16x16 pixels

	CRect r;<br />
	VERIFY(dc.GetClipBox(&r) != ERROR);<br />
<br />
	CBrush *b = new CBrush(theApp.m_gridColor), *ob;<br />
	CPen *p = new CPen(PS_SOLID, 1, theApp.m_gridColor), *op;<br />
<br />
	ob = (CBrush*)dc.SelectObject(b);<br />
	op = (CPen*)dc.SelectObject(p);<br />
<br />
	x = r.left >> 4;<br />
	x2 = r.right >> 4;<br />
	y = r.top >> 4;<br />
	y2 = r.bottom >> 4;<br />
<br />
	// Just vertical for now<br />
<br />
	for (Sint32 i = x; i < x2; i++)<br />
	{<br />
		dc.MoveTo(i << 4, r.top);<br />
		dc.LineTo(i << 4, r.bottom);<br />
<br />
		if (i % theApp.m_thickGridInterval == 0)<br />
		{<br />
			dc.MoveTo((i << 4) + 1, r.top);<br />
			dc.LineTo((i << 4) + 1, r.bottom);<br />

On WinXP, I can receive the message NIN_BALLOONTIMEOUT and NIN_BALLOONUSERCLICK when balloon hide because timeout or click on it. But on Win2K, I have got nothing.

It's better idea to get the position of the icon on system tray.

Please advise how to get the position.

Thanks.

Probably what you mean is if atleast one application instance
is running ?

What you need is to just enumerate the process list
and look at the exe or the program name.
Process32First, Process32Next.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
