If all you changed was the derivation from CDialog to CPropertyPage, you didn't quite make it. Create a new class using the Wizard and derive that class from CPropertyPage. Then make sure your base class calls for your classes match the generated ones.

Hi all,
I'm trying to restore a window state to SW_RESTORE using the method ShowWindow. But as easy as this sounds I'm trying it in a dll. And for some reason i'm not getting it right.
I'm trying the following:
HANDLE ps = OpenProcess(SYNCHRONIZE|PROCESS_ALL_ACCESS,FALSE,pe_sen.th32ProcessID);
SetForegroundWindow(ps);
ShowWindow(hWnd, SW_RESTORE);
But one thing I must add is that I'm not creating a process, I'm just checking if a certain process is already running on the PC.
So I have seached all over the web and can't get anything that can help me, so if anyone has some info of a site or .... anything. It would make my day.
Thanx in Advance
Regards

You are passing a process handle into a function that expects a window handle. A process can have more than one window.
http://msdn.microsoft.com/msdnmag/issues/02/07/CQA/[^]
SetForegroundWindow() on Windows XP will just cause the app to flash in the taskbar if the window doesn't belong to the calling thread. You can use AttachThreadInput to get around this.

Nobody writes this code. It's the class wizard that inserts this code (for its marking) for adding the member functions and data members that belong to this class and so on.
What do you don't understand?
If its those brackets
//{{ these fancy brackets are used for denotation by the class wizard where to add functions and variables.

Nirmal,
you'll have to conform to the forum rules if you want people to still help you.
stop creating a new thread if the topic stays the same. continue in the same discussion, and be patient. people will see your request and answer it if some knows the answer. 
for what you ask, this code is automatically generated by class wizzard (so no one wrote it), but this code actually defines the CAboutDlg class (which is the Dialog box of your "About").
what don't you understand in this ?
//{{ and //}} are comments, so don't take them in account

the flipping functionality.

Set breakpoints in your code and step through to see which part is causing the error.

Hi,
I want to store a list of strings. Something like this:
Name1 a1
Name1 a2
Name1 a3
Name2 b1
Name2 b2
For just a list of Name’ i.e. Name1, Name2 ‘I can use CStringList. But how do I store the ‘Name’ and its corresponding data in a single list.
I cannot use an array[][] because I do not know the exact size to allocte it at runtime.
Please can you tell me how to do it.
Maybe I can store the whole line as a string i.e. Name1 a1”“ and then use sscanf to get the separate strings?? Would that be correct?

Is Creating SAFEARRAY of type VT_BSTR has any problem ?

An class declaration eritten below. i can't understand how it is written, i.e. which is base class & which is derived class & WHICH ARE THE MEMBER FUNCTIONSplz help me to make it clear???
CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD)

Nirmal Khatri wrote: CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD)
this is not a class declaration. It is the definition of the custructor of the class CAboutDlg.
Actually there will be class called CAboutDlg derived from the class CDialog like below.
class CAboutDlg : public CDialog<br />
{<br />
public:<br />
CAboutDlg();<br />
<br />
enum { IDD = IDD_ABOUTBOX };<br />
<br />
protected:<br />
virtual void DoDataExchange(CDataExchange* pDX);
<br />
protected:<br />
DECLARE_MESSAGE_MAP()<br />
};

This is not the declaration of a class
This is the constructor of the class CAboutDlg and is derived from CDialog

I wrote my class public from CColorDialog

BOOL CColorDialogExt::OnInitDialog()
{
CColorDialog::OnInitDialog();
m_pRed->Create(WS_EX_STATICEDGE | WS_EX_CLIENTEDGE | ES_LEFT | WS_CHILD | WS_VISIBLE | WS_TABSTOP ,CRect(445, 203, 475, 220), this, 1000);
m_pGreen->Create(WS_EX_CLIENTEDGE | ES_LEFT | WS_CHILD | WS_VISIBLE | WS_TABSTOP ,CRect(445, 225, 475, 242), this, 2000);
m_pBlue->Create(WS_EX_CLIENTEDGE | ES_LEFT | WS_CHILD | WS_VISIBLE | WS_TABSTOP , CRect(445, 247, 475, 264), this, 3000);
return TRUE;
}
So, three edit view ok, when i change color, i want to get color value (COLORREF)
but i can not get it.
( action : OnLbuttonDown)
Can you help me now?
Thank for advance.

forst get the color value (COLORREF actually it is a DWORD)
use the following macros
GetRValue - for Red value
GetGValue - for Green value
GetBValue - for Blue value
this will return a byte value.
format to hex value using sprintf or CString.Format functiion
put these values to your edit boxes.
