Preach it brother! Halleluya! 
By the way, I went to a Christian church for the first time a couple of weeks ago and saw the preacher "healing" a bunch of cancer-ridden people. As he was chanting over each one of them, I noticed that several of them were fainting and falling backwards, just like on TV! 
What is your explanation for this behavior?
Also, I was only there for about 30 minutes -- got there late -- and I swear I must have counted about 30 Halleluyas coming from the preacher. Overall, it was an interesting experience.
Regards,
Alvaro

Hmmm... According to the Bible, anyone can pray to God and expect to be healed. I know several people healed of cancer, including one who was prayed for when not a Christian and was converted as a result of being healed by God.

Groupthink ? Basically people fall over because they know it's expected of them/encouraged. The Bible has nothing to say about people falling over, it's part of the circus many 'modern' churches engage in. In fact, they call it being 'slain in the Spirit', the closest the Bible comes to referring to this is when God *KILLED* people in the Old Testament who opposed Him. The 'slain of the Spirit' in the Bible were dead, dead, dead.

I spawn a modeless CDialog derived object from my MDI view class. When the user closes this CDailog with the system menu, I want to get rid of it totally.....
I did a new to create it in the View. If I put a delete this in the destructor of the cdialog is that enough? Also I created this object locally. Is there a problem with that and doing the delete? (if indeed the delete is legal..?)
Appreciate your help,
ns

Some points:
1. Putting "delete this" in the destructor will not work. If the destructor is being called it's because the object is already being destroyed. So if you try to destroy it again... 
2. The proper way to get rid of modeless dialog boxes is with DestroyWindow. Call that inside your OnCancel or OnOK functions. Alternately, you can do a "delete this" instead, which will call DestroyWindow. However, "delete this" will blow up if the dialog box is not created with new every time, so be careful.
3. If the dialog is modeless, the user will be able to create more than one of it. If that's not OK with you, how do you prevent it?

Alvaro

urgh.....only one Cdialog to be created....I havent thought of it yet...maybe set some sort of flag?
I dont have an onOK or onCancel.....I just want the dlg dismissed with the system menu. So thats why I thought if I did delete this in OnClose() it might work? I didnt state this yet so what do you think about this idea?
you said" it will blow up..." why ?
Appreciate your help,

Here's what I would do:
1. Use this code to create the dialog box:
static CMyDlg s_dlg;
if (!::IsWindow(s_dlg.m_hWnd))
s_dlg.Create(CMyDlg::IDD, this);
s_dlg.ShowWindow(SW_SHOWNORMAL);
2. Inside your OnClose, call DestroyWindow();
This ensures your dialog is created only once and that it's properly destroyed.
ns wrote:

Sorry, typo. I modified my post. I meant that it will blow up if you call delete this and the dialog is not created with new. It's because it will try to free memory from the heap which wasn't allocated on the heap to begin with.

Alvaro

Many thanks!
Quick question:
I've got three (actually decided at run time) buttons on my project and each will spawn a CDialog. If I use the same variable s_dlg is it okay? (No static right? )THe only things i will do with these CDlgs is a. close them, or b.resize them. So in the OnClose, with your strategy, will the code know which window to destroy? SInce now s_dlg is only pointing to the last CDlg created....
Appreciate your help,

Well, if it's 3 separate dialog boxes, I recommend you create 3 separate methods, each with its own static object:
void CMyView::OnButton1()
{
static CMyDlg s_dlg;
s_dlg.Create(this);
}
void CMyView::OnButton2()
{
static CMyDlg s_dlg;
s_dlg.Create(this);
}
void CMyView::OnButton3()
{
static CMyDlg s_dlg;
s_dlg.Create(this);
}
Then you can add this method to your dialog class:
void CMyDlg::Create(CWnd* pParentWnd)
{
if (!::IsWindow(m_hWnd))
CDialog::Create(IDD, pParentWnd);
ShowWindow(SW_SHOWNORMAL);
}

Great article! Also need to know ....this CDialog is merely informational. So I dont refresh it (may resize it), so is it better to use a local variable or a member variable? I can easily push the pointers onto a vector, so thats not a problem....I just dont knoew if its necessary> Can I use the info in the article in the event that I create a local variable each time the button is pressed to spawn a new dlg?
Appreciate your help,
ns
what I have are a set of cdlgs which in turn send messagse to the view when their button is pressed, wehich spawns the other CDlg. SO yes I can have many CDlgs - thats okay, but only one for each original CDlg which sent the message (the one with buttons)

One solution is to declare a pointer to the dialog box as one of view's private members.
Inside OnClose(), call DestroyWindow(). Inside PostNcDestroy(), call
CDialog::PostNcDestroy() and delete the object via "delete this." Post a message to the view class and set the pointer to NULL.

Put the "delete this" into the PostNcDestroy handler of your dialog.

I might work if you put on WM_DESTROY. If you put in the destructor it will never be called at best, or called recursively on the deleted object(read undefined).

I am drawing some figures and storing these figures as bmp file. All of this drawing is
done on a window that is not shown to the user.
This is done by using
memDC.CreateCompatibleDC(NULL);
bitmap.CreateCompatibleBitmap(&memDC, 600,400);
Now this memDC is used for drawing diffrent figures.
as memDC.Rectangle(---);
I use diffrent color of Pens to draw figures.
It works fine in normal case but in mine case when diffrent colors of pens are selected
only black color is displayed for all figures.
Help me so that using
memDC i can create figures generated by diffrent color of pens.
I hope this has clarified you.
Thanks.

try using NULL as the DC for your CreateCompatibleBitmap. when you use the memDC, you'll always get black & white.

I'm using directdraw, and I got a problem.
I'm making a pong game, and I don't know
how to change the color of the rectangels
that the game is going to be build at.
Without ddraw, I'm doing that:
HDC hdc;
HPEN hPen;
HBRUSH hBrush;
hPen = GetPen (PS_SOLID, NULL, RGB(0,255,0));
hBrush = GetSolidBrush (RGB(0,0,0));
PAINTSTRUCT ps;
BeginPaint (hdc, &ps);
Rectangle (hdc, 23,54,100,249);
EndPaint ();
(I don't think the code is totally correct)
And it works!
When using ddraw, I'm writing something like this:
HDC hdc;
lpDDSBack->GetDC (&hdc);
Rectangle (hdc, 23,54,100,249);
lpDDSBack->ReleaseDC (hdc);
lpDDSPrimary->Flip (0, DDFLIP_WAIT);
WHERE IN THE H*LL DOES I PUT THE COLORS????
please, help me!!!
My english is bad?
Who cares!

I am editing a customer's code. It has a dialog with some buttons on it. IDOK and IDCANCEL are not present. I would like to select one of the buttons to be activated like a single button click. After the button has been activated, I would like to move the default button to another button. The tab stop is selected on each button, but tab does not bring up a focus.
TIA
Steve

I'm not sure what you need exactly, but it seems like you want to set the focus on a button. For that, SetFocus() should do the trick.
If you still need help, please post some code or try explaining the problem again.

Alvaro

One solution is to set the current default button. Here is an example.
-----
DWORD style = m_BtnA.GetStyle();
// Make sure ButtonA is not already the default button
if ((style & BS_DEFPUSHBUTTON) != 1)
{
// Get style of ButtonB
style = m_BtnB.GetStyle();
// Remove default push button style
style &= ~BS_DEFPUSHBUTTON;
// Set the style of ButtonB
::SendMessage(m_BtnB.GetSafeHwnd(), BM_SETSTYLE, (WPARAM)style, (LPARAM)TRUE);
// Inform the dialog about the new default control ID
SendMessage(DM_SETDEFID, m_BtnA.GetDlgCtrlID());
// Get the style of ButtonA
style = m_BtnA.GetStyle();
// add the default push button style
style |= BS_DEFPUSHBUTTON;
// set the style
::SendMessage(m_BtnA.GetSafeHwnd(), BM_SETSTYLE, (WPARAM)style, (LPARAM)TRUE);

Thanks for the suggestions. They will be very helpful for the next part of what I want to do once I solve the main problem. Upon further examination, I find that this is an MDI problem.
The MDI child window is being opened. The buttons I want to access are in the child window.
Upon opening of the child, hitting TAB or ENTER has no effect. If I click the buttons with the mouse, I now have TAB and ENTER control thoughout.
I can trap keystrokes in MainFrame. So the Mainframe seems to have the focus for keyboard input.
The big question:
How, once I have made the Child window, can I place the default focus inside of that window so that keystrokes are sent to the child windows controls?

You can start by learning about the how security works under Windows. A great article to give you a good introduction can be found through MSDN at http://msdn.microsoft.com/library/en-us/dnsecure/html/msdn_secguts.asp?frame=true[^].
From there you will have a better understanding of some of the data structures and functions used in the security APIs, and how you can then use them to manipulate users, groups, DACLs and the like.
Once you finish reading the article, you will find on the left side a menu with an Option of "Security". Click that and go down to "Security General" and finally to "SDK Documentation" and take a look at all the functions you can take advantage of on the Windows platform.
Good luck!

I want to write a simple windows program that lets me run a dos program with different buttons for different arguments. (I use visual C++, but I'm quite a newbie to windows programming).
1. user makes sure my (front-end) program is in the same directory as the dos program.
2. user specifies the arguments (the bits that come after the the program name ie: program_name.exe -h) (the -h)
3. user specifies a filename for the input/output files (ie: program_name.exe -h input_file.bmp output_file.tgo
Any help would be graciously appreciated.
Thanks.
