NOTE:
If you don't know how Property sheets work, continue reading, if you already know, don't continue... Wink | ;)

Well, a "CPropertySheet" it's a container class, it contains several "CPropertyPage"s.

in order to make it work you must follow those easy steps:

1. Create a dialog for each "page" you need.
2. Place all the controls inside the dialog using the resource editor.
3. Then you'll need to map all the messages you need, in order to do so, create a class for the newly created and populated dialog, and select the class CPropertyPage.
4. Repeat step 2 and 3 until you've finished to populate/define the recently created property pages (dialogs).
5. Now you must create a new class from the class wizard, select the base class CPropertySheet.
6. Modify the newly CPropertySheet in order to add the required pages in it's constructor.
7. Call the property sheet from your code.

this is how it works...

hope this helps...

I don't understand you: if you have one thing inside another, normally the child window is not resizeable and neither it can be moveable...

have you created the new window as a child of the parent one?

Hi,
No I am creating a window in OnSetActive() event of the propertyPage that contains it.I don't know how to make it a child.
My code looks like this:
//CReportWizPage is a propertyPage on which i want to create the Tabbed Pages.
//CReportTabbed is the PropertySheet that embeds these pages.
CReportWizPage::OnSetActive()
{
CPropertySheet* psheet = (CPropertySheet*) GetParent();
psheet->SetWizardButtons(PSWIZB_BACK | PSWIZB_NEXT);
CReportTabbed report(IDS_TABBED,this);
CReport1Tab rep1;
CReport2Tab rep2;
report.AddPage(&rep1);
report.AddPage(&rep2);

if(report.DoModal() == IDOK)
{
//........
}
return CPropertyPage::OnSetActive();

}

if you use DoModal(), then you are making the property sheet appear as a standalone component that isn't owned by nobody (only by the app).

<br />
this->m_pPSEstacio = new CPSEstacio("", this, 0);<br />
<br />
	this->m_pPSEstacio->Create(this, WS_CHILD | WS_TABSTOP | WS_VISIBLE);<br />
	this->m_pPSEstacio->ModifyStyleEx(0,WS_EX_CONTROLPARENT);  // if you don't do this you won't be able to get access to the parent's window controls by pressing tab...<br />

Hope this helps...

Problem with displaying images

Franz Klein16-Jun-03 1:10

I am having some trouble getting images to display properly.

What my real problem is as follows.

I have an image displayed and am able to drag a rectangle over parts of the image. I am able to get a copy of the image that is selected by the dragged rectangle. With this image copy I change it to black and white. Now I want to display this copy on the original image. The problem I have is that it doesn't display where I dragged the rectangle but some place else. I used pDC->DPtoLP(point) when I captured the points for the rectangle. I use the same points again for the place where I want the copy of the image to display again.

Can anybody help? or direct me to a good tutorial.

Lint-like .h-file tool

During the lifetime of a C/C++ project several header files are
added because source snippets are moved between source-files. Seldom
are any header files removed. It's to much work to manually walk through
each source file and check if a header is no longer needed.

So, is there any tool (besides Gimpel's PC-Lint which is beyond my
budget) that can tell me which headers are no longer needed? It would
need to understand C/C++ off-course

Thanks guys, I d/l SPlint 3.0.1.6 and read some of the docs. But failed to
find what I'm looking for. Are you sure it can do this? (see 1st
message).

Font in dynamically created tab control

roel_15-Jun-03 23:44

Hi,
I've got a tab control that I created dynamically, like this:

m_TabCtrl.Create(TCS_TABS | TCS_MULTILINE | WS_CHILD | WS_VISIBLE, CRect(0, 0, 0, 0), this, 123)) {

Somewhere else I resize the tab to the size it needs to be. I add some items to the tab control, that's all fine; the problem is that the font is wrong. It's the default system font, the one you get when you run out of GDI resources. I've been trying to use SetFont() on the tab control, but that doesn't make any difference. How should I go about it? All other controls use the right font; can I copy it from there and set it on my tab control? Should I use GetFont/SetFont for that, or the LOGFONT that I can get through GetFont? I'm offically confused now WTF | :WTF:

Thanks in advance.

cheers

Have you tried this?

m_TabCtrl.SetFont(GetFont());

If you do that after you create it, that should work. That's what I usually do to set the font of a control. It may or may not work depend ing on where you actually create the tab control, if you're doing it in any CWnd derivative then it should be ok.

Thanks for your reply Ricky - the problem is that GetFont() returns NULL when I call it from within OnCreate() of a control (not only on the tab control btw, also my CMDIChildWnd()-derived class). What controls have a font set? And when is it set?

Yes, according to MSDN
(Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.)

However, there's no progress indication - so for a long file it will just sit there. CopyFileEx allows progress and cancelling - but it's NT4+ only
