Hi!
I'm making a simple mapeditor in MFC for a game and I would like to add a new window where the user can see the map renderd in openGL.
So I'm simply looking for an article on how to create a new independent window in my MFC project. I've searched the site, but i haven't found anything. Can anyone help me find it?
Thanks!

I'm using this project for the basis of my learning. However, I'm having trouble incorporating the class into my project. I read about device contexts and such but I couldn't find a straightforward sequence of steps to change my app to accept the new routines. I'm looking for information on what type of code to add and where, not a simple copy and paste job, but something concise. For instance, adding "CDC *pDC;" to my app class, and to add "pDC = pFrame->GetWindowDC();" is what I'm looking for. I tried to read through the project demonstration mentioned above to pick out the information but there's too much to wade through. Can anyone help me out?

Hey Folks,
Newbie. I have many dialogs using buttons. The text fits great on my computer, but when I load the program to other computers the text is too big. I assume that this is font management but I don't really know how to control them. Please point me in the right direction.
Thanx.

you are try func "SetFont" to set font .
e.g
CDialog dlg;
CFont font;
font.CreateFont(...... );
dlg.SetFont(&font);

void switchn()
{
char command = menu(); // works ok here
switch ( command )
{
case 'e':
case 'A': cout << "plebs";
break;
case 'j':
case 'B': cout << "flebs";
break;

}
getch();
return;
}
char menu(void)
{
char a;
cin >> a;
return a;
}

Your first location is not in a normally executable region of your source file.
At best, it is executed once when the program starts (to assign a value to the global variable command), but not ever again.

In an MDI app , if the user maximizes the main frame , how should i resize the view ?
Do this idea work
CMainFrame::OnSize(...)<br />

I'm trying to create a button on a property sheet (not a property page). Here's what I have for creating the button:
SetWindowPos( &wndTopMost, 200, 100, 700, 500, SWP_SHOWWINDOW );//This is the property sheet window
pWnd = GetParent();
m_btnRead.Create("Button Text Here", WS_CHILD | WS_VISIBLE | WS_TABSTOP | BS_PUSHBUTTON, CRect(10, 50, 690, 490), pWnd, 1);
The button never shows up anywhere, no matter what coordinates I put in.
Am I using CRect incorrectly? Or am I just missing the obvious somewhere?
I do apologize for asking this, but I've never worked with property sheets before and I've always just dropped the buttons onto the dialog where I needed them (yes, I was being lazy).
Any help is appreciated.

If this code is IN the property sheet, you problem might be with the GetParent() call. You are getting the parent of the PropertySheet, which might very well be the desktop...
Try leaving out the GetParent() call and use this instead. (Keep in mind your child coordinate are relative to upper left corner of property sheet, and not entire screen...)
m_btnRead.Create("Button Text Here", WS_CHILD | WS_VISIBLE | WS_TABSTOP | BS_PUSHBUTTON, CRect(10, 50, 690, 490), this, 1);

Thank you for responding. However...

It is indeed in the Property Sheet. I'm trying to create buttons when the Property Sheet is called (or launched).
I tried leaving out the GetParent() call, but still nothing.
The MSDN says that for creating buttons, the parameters should be:
Create( LPCTSTR lpszCaption, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );
I'm curious about something here: if I'm not calling GetParent, how exactly would I reference the parent window? "this" doesn't work and, as far as I can tell, there is no variable for it or really any way to reference it since it's a CPropertySheet class and I need a CWnd class for the 4th parameter.

The width and height of the Property Sheet are: 700 and 500. That's why I put the coordinates at 690 and 490. As far as I can tell, that should put it in the bottom right corner. Or am I misreading it?

My analysis would eventually lead to what PJ Arends is already telling you (in other messages). I think there is something not quite right in your system.
Anyway, the 'this' of a CPropertyShett will be cast to a CWnd, since the CPropertySheet is derived from a CWnd. That is why I asked if your code was part of a CPropertySheet member function.

The parent window of the button should be the property sheet. It looks like you are making the button a sibling of the sheet, not a child of the sheet. Also, and I do not know if this is affecting your button creation, but you are using the ID of 1, which is the same as the ID of the OK button which already exists on the sheet.

Okay, this may be a stupid question, but am I not declaring the parent window as the property sheet? Where am I making it a sibling instead of a child?
I changed the ID, but still nothing.

Ok, just for the heck of it do this
int CMyPropertySheet::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CPropertySheet::OnCreate(lpCreateStruct) == -1)
return -1;
if (!m_MyButton.Create(_T("The Button"),
WS_CHILD | WS_VISIBLE | WS_TABSTOP | BS_PUSHBUTTON,
CRect(30, 30, 1024, 768),
this,
ID_MY_BUTTON))
{
ASSERT (FALSE);
return -1;
}
return 0;
}You should now have one huge button that takes up your entire sheet and then some. Now play with the size and position until you get the button where you want it.

Nope; no button.
Could it just be that new buttons can't be created directly onto a property sheet? I would think that they could because you can remove buttons or move them around (which I've done).
What am I missing here?

Unless the create function failed the button has got to be there. Grab Spy++ and look up your sheet, check out what it's child windows are. Your button has to be there. I tried the code I posted before I submitted it and it worked just fine here.
I am at a loss as to what you are doing wrong, because I use this method to add several buttons and a bitmap to my property sheet.

According to Spy++, none of the buttons (yours or mine) are there. It lists the other things associated with the property sheet, including the OK and Cancel buttons, but the buttons that I'm trying to create (which includes the code you supplied as a test) aren't there.
 This is driving me crazy.

Place a breakpoint in the OnCreate function just to make sure the code is actually being run. Did you remember to add the ON_WM_CREATE() macro to your message map?

Yes, I did.
According to the step-through, it is entering OnCreate and moving to the Create line for the button. It is returning 1, but that, according to the message, is success. So, it's saying that it is creating it. I just don't know where it's creating it at since it's not showing up anywhere on the property sheet.
Everything else that I'm doing in OnCreate and OnInit work. Buttons are removed or moved, the menu is added, all of it; everything except creating the buttons.

Ok, in the debugger check what the value of the button's m_hWnd variable is. Then in Spy++ bring up the window finder dialog (Ctrl + F) and enter that value in the handle edit box. Click Enter. You should now be able to tell which window is the parent of your button, it should be the property sheet, if not what is it?

According to the debugger, the hWnd of the button is 0x00000000. Spy++ says "specified handle is not vallid". I knew that as soon as I saw it, but I tried it anyway.
So, what's happening here? It's being created (it's returning a non-zero value indicating success), but it doesn't have a valid handle. Is it just being created and then destroyed before getting added to the property sheet?
Any ideas?
