You can't show it in a text- or RTF-box, you'll have to automate Word.

There is a lot of information on MSDN on this, although spread on 1 000 000 articles, and with most samples in VB, so search MSDN for - for example - Word and automation - and be patient Smile | :)

CStatic Z-Order in dialog

So total noob question, I've hunted high and low for this but still nothing.

I have a Static control overlayed on top of a Group Box. I'm using the Static control as the title for the Group Box. The Static control is being displayed behing the Group Box. I need it to be on top.

Here's what I've tried in the CDialog::InitDialog()

/*c_TextSpecifics is my CStatic control*/
c_TextSpecifics.SetWindowPos(&wndTop, 0,0,0,0, SWP_NOSIZE|SWP_NOMOVE);

This has no affect. Anyone know how to get the CStatic control on top?

I assume that you did know one crucial fact: that you can give a caption to the group box by using the dialog editor, and that you can change the caption by using the following code fragment:

// Using the dialog editor, add a group box into the dialog template, and use the Properties sheet to change it's ID to IDC_MYGROUPBOX<DIV>

// First, we need to obtain a pointer to the object. As the group box is a general static control, the CWnd class can support it.
CWnd* pGroupBox = (CWnd*) GetDlgItem(IDC_MYGROUPBOX);
pGroupBox->SetWindowText("New group box caption");

This code fragment can be called from CDialog::InitDialog, and will do the job.

If you MUST use a static label control, then the answer here is to use the &wndTopMost parameter for SetWindowPos. However, this means that you must manually change the static control back to non-topmost window whenever it goes behind some other window (your window loses focus).

Alter the tab order of the controls within the dialog. The Z-Order of dialog controls is controlled by the tab order.

Override OnOk and OnCancel functions (to do nothing or if you would like to handle them do not call CDialog::OnOk (OnCancel) in them).

If CTestDialog is ur Dialog class, then add implementation

void CTestDialog::OnCancel()
{
//Remember the function body has nothing
}

the problem was occuring because ur app must have had the implementation below:
void CTestDialog::OnCancel()
{
CTrayDialog::OnCancel();
}

<br />
void yourclass::OnCancel(){<br />
  //do something but do not call CDialog::OnCancel();<br />
}<br />

I once had the same problem and I solved it like this.
(try both OnOK and OnCancel maybe)

if this doesn't work I wouldn't know sorry.

Does anyone know how I can track which window in my app has the focus. Using break points causes the focus to shift to visual studio and I dont want to add an OnSetFocus() method with trace statements everywhere

Run a Timer function and call GetFocus() from within the timer function.

Creating a Trial version of a program

I would like some suggestions on how to create a version of my program for use as a trial. I want the program to either quit working after a specified date or to only run X number of times. What are methods to do this that can't be hacked around?

You cannot make it 100% unhackable

You could reduce the features and not ship the code that implements the disabled features. People cant run code they dont have.

Almost all of the ways possible to make a program shareware are possible to go around. One way to do it is to encrypt a hidden key somewhere in the registry with the set date to expire that an uninstall utility wouldn't remove.

The most secure way I can think of would be to make the user create a user name and password to register it. When you registered it it would notify the host of the usernames and increment the number of times the username/password combination has been used. If the number approaches a specific value you could delete it. This would require the user to have internet access, which most do.

Those are my ideas....I dont know how they would work.

Control Problem

I'm using OpenGL on a dialog based MFC application. It works fine and well until I try to open a messagebox. Then the program freezes. I'm not sure why. By cutting certain lines of code out, I have discovered that the only lines that stop the problem from occuring that I can remove is:

<br />
CString className = AfxRegisterWndClass(<br />
		CS_HREDRAW | CS_VREDRAW | CS_OWNDC,<br />
		NULL,<br />
		(HBRUSH)GetStockObject(BLACK_BRUSH),<br />
		NULL);<br />
CreateEx(<br />
		0,<br />
		className,<br />
		"OpenGL",<br />
		WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | WS_CLIPCHILDREN,<br />
		rect,<br />
		parent,<br />
		0); <br />

I dont see how this could cause the error, but I think it does. If anyone can tell me how to make it not freeze when I display a message box I would appreciate it. Thanks a bunch.
