I have a CPropertySheet which has two property pages in Wizard mode. In my OnWizardFinish handler on the second page I do an EndDialog(IDOK). I then call another modal dialog, dialogB. The wizard dialog does not go away until dialogB is dismissed and the return from the OnWizardFinish is executed.
- Is there anyway to make the wizard dialog go away immediatly, the EndDialog does not seem to do it?
- I've unchecked the System Menu resource from the wizard dialog. The CPropertySheet puts the system close button (X) in the upper right corner. Is there a way to remove it?

Thanks in advance,
Bob

As for your first question, probably calling CMyPropertySheet::ShowWindow(SW_HIDE) before launching the second dialog will do.

Thanks for your response. This has no effect, the dialog is still behind the latest one, as it was before.

You sure? Try this sequence:ShowWindow(SW_HIDE), launch dialog, EndDialog.

   Are you calling ShowWindow( SW_HIDE ) directly from within the OnWizardFinish() handler, or are you calling GetParent() -> ShowWindow( SW_HIDE )?

   As for the system menu, you can try specifying WS_POPUP without WS_SYSMENU when you create the Property Sheet, or modifying the Sheet's styles after creation.

   Unchecking the System Menu in the Dialog/Resource Editor does little for you in this case, because the dialog editor is used to modify the Pages, not the Sheet.

   Peace!

James,

The GetParent()->ShowWindow(SW_HIDE) does the trick, thanks.
How would I modify the Sheet's style after creation to have WS_POPUP without WS_SYSMENU? I assume I would do it in it's OnInitDialog()?

Thanks,
Bob

I've got it, it's ModifyStyle (WS_SYSMENU, 0) in the Sheet's OnInitDialog.
Thanks for your help.

why not just have whatever called the CPropertySheet call the dialog whenever it returns?

if (MySheet.DoModal() == ID_WIZFINISH)
{
dialogB.doModal();
}

if you have a good reason then ignore my question Smile | :)

I have a worker thread that is carelessly updating the status bar. It's causing a GPF. This involves a large complex application framework, which isn't easily changed. I would like to change my MFC status bar code to be thread safe. Is there a way to do this? Would this work: Have the status bar store a HWND, and whenever accessed, construct a CStatusBar FromHandle?

Create a user defined message and make the thread post it from time to time to the main application thread (i.e the one that owns CMainFrame). Then all the updated will be done by the thread that owns the status bar.

In that message you will send the completion percent (10%, 20%). Read this article by Joseph M. NewCommer: Using Worker Threads

Is there an easy way to determine if I'm in a worker thread vs the main thread? I tried calling:

if( AfxGetMainWnd() )

expecting that it would return NULL if it was the worker thread, based on an article by NewComer on CodeProject. However, it didn't return null in the worker thread. Any ideas?

hi
when i tried to declare an object that take CString constructor as follow:

Group groupA("France", "Senegal", "Uruguay", "Denmark");

it just give me this error:

: error C2059: syntax error : 'string'

and this is my constructor implementation:

Group::Group(CString t1,CString t2, CString t3, CString t4)
{

team.Add(t1);
team.Add(t2);
team.Add(t3);
team.Add(t4);

}
and i've tried this one also and by the way what is LPCTSTR??

Group::Group(LPCTSTR t1, LPCTSTR t2, LPCTSTR t3, LPCTSTR t4)
{

team.Add(t1);
team.Add(t2);
team.Add(t3);
team.Add(t4);

}
What is going on??? Thanks heap for you help

Hm, maybe there's a problem with the team member variable. How it is defined?

A LPCTSTR is a const pointer to an ASCIIZ string. If it's really ASCII/ANSI or Unicode depends on your compiler settings.

looks like you're using a type called "string" somewhere, but you haven't #include'd the appropriate header.

where does the syntax error occur??

LPCTSTR is a pointer to an array of TCHARs. a TCHAR is some character type (char, wchar, etc) depending on your build settings.

The code

Group groupA("France", "Senegal", "Uruguay", "Denmark");

is not passing CString objects to the constructor.
This code

Group groupA(CString("France"), CString("Senegal"), CString("Uruguay"), CString("Denmark"));

is.

The code

Group::Group(LPCTSTR t1, LPCTSTR t2, LPCTSTR t3, LPCTSTR t4)

should work unless team.Add(...) is also wanting a CString object.

Hope this helps... Smile | :)

LPCTSTR = Long Pointer Constant To String Portable for UNICODE.

If you use the CString constructor you must pass CString objects not a char*

You can cast them directly
Group (CString ("France"),...)
but it is not worth it becasuse it will create some useless objects.

Use LPTSTR = Long Pointer To String Portable for UNICODE. You can see it is not a constant.

yeah, i understand it now. however it keeps produce another error.

this my class definition for the Group Class
class Group
{
public:

Group::Group(CString t1, CString t2, CString t3, CString t4);
CString Group::GetTeam(int i);
void Group::PutResult(int t1, int s1, int t2, int s2);
void Group::GetLadder();

private:

CStringArray team;
int res[4][4];

};

and this is my implementation for the constructor:

class Group
{
public:

Group::Group(CString t1, CString t2, CString t3, CString t4);
CString Group::GetTeam(int i);
void Group::PutResult(int t1, int s1, int t2, int s2);
void Group::GetLadder();

private:

CStringArray team;
int res[4][4];

};

and this is how i used it in the Doc

Group groupA(CString("France"), CString("Senegal"), CString("Uruguay"), CString("Denmark"));

and this is the error it produces

unexpected 'class CString ('

1. It looks that you missed the copy paste thing. The implementation and the source code look the same [ Smile | :)

]

2. Why do you prefix the functions inside the class?
class A
{
int A::f (); // you can say int f()
}
