Problem with CPropertySheet class

spielehelfer27-Nov-06 2:27

Hi, I've got some Problems with CPropertySheet in the development of a C++ application in emVC++.

Problem is:
I have a PropertySheet width 4 pages (all same size 260*92); but they all get cut of at the right side.
So I startet do derive a class from CPropertySheet and overwrite the OnInit Method like in this project: Free size and extended styles in CPropertySheets

This brought me a few Problems:
- the CPropertyPage* pppg = GetActivePage(); causes access violation so I changed it into CPropertyPage* pppg = GetPage(0);
(curious from outside, in the dialog class i can use GetActivePage(), inside I only get a 0x0 pointer)
- also the pppg->MapDialogRect(rcOriginal); causes access violation and all other Methods that later on uses pppg too.

This brings me down to the problem that I cannot read out the PropertyPage size on runtime and have to use fixed values to resize.

so only these lines had been left from all the code:

<br />
	BOOL bResult = CPropertySheet::OnInitDialog();<br />
	<br />
	ModifyStyleEx(0, WS_EX_TOOLWINDOW);<br />
	CRect rcModified;<br />
<br />
	//Tab<br />
	GetTabControl()->GetWindowRect(rcModified);<br />
	ScreenToClient(&rcModified);<br />
	rcModified.right +=50;<br />
	GetTabControl()->SetWindowPos( NULL, 0,0, <br />
						rcModified.Width(),<br />
						rcModified.Height(), <br />
						SWP_NOMOVE | SWP_NOOWNERZORDER | <br />
						SWP_NOZORDER | SWP_NOACTIVATE );<br />
<br />
<br />
<br />
	//Sheet<br />
	GetWindowRect(rcModified);<br />
	ScreenToClient(&rcModified);<br />
	rcModified.right +=50;<br />
	SetWindowPos( NULL, 0,0, <br />
						rcModified.Width(),<br />
						rcModified.Height(),  <br />
						SWP_NOMOVE | SWP_NOOWNERZORDER | <br />
						SWP_NOZORDER | SWP_NOACTIVATE );<br />

Anyone has an idea why I cannot acces the ActivePage() or also the work with the PropertyPage reference loaded by GetPage(0) causes access violations?

The Create() call of CImageList class takes a parameter for color mask (COLORREF crMask). Is it possible to change this mask after creating it?

How to achive application load balancing in win32 application

27-Nov-06 2:04

Hi,
My application is having two threads. One is UI thread doing all UI operations. The another thread is doing some heavy work like writing to disk. How I can achive that only when the system have a light load then only the disk writer thread will run and in heavy load cases it will not schedule or scheduled for very low time?

How can I know that when system is not heavily loaded and when it is heavily loaded?

Is the "Load Balancing" word correct here or it is misleading?

Regards,
Hemant.

I don't know that you can perform load-balancing as directly as you want to. However, the Windows API offers the 'CreateThread()' and 'SetThreadPriority()' functions, which allow you to create a thread and set its priority. For example, we can create a thread and set its priority to LOW, in which case the operating system will AUTOMATICALLY schedule the thread for execution in such a way that other, higher priority threads will receive more CPU cycles.

This is probably the best way to handle this anyway, as the operating system can allocate CPU cycles more efficiently that you could.

In your example, the disk writer thread would be given a low priority. As other tasks are invoked, such as user interface actions, Windows will automatically suspend the desk writer thread and give priority to the user interface.

Check out the documentation on 'CreateThread()' and 'setThreadPriority()' for a better description.

I am having one MFC application ,which is also having one ATL interface.
when I am running this application standalone there is only one instance of application and it is fine.
But if my this EXE is already running and any clients wants to access interface provided by this exe , then there will be two instances of same exe running, I want to avoid it.

What i have done is I have registered this exe with ROT,and when client wants some interface provided by this exe,itcan get it from ROT, but I am facing the problems in getting the appropiate interface from ROT

any help....

The same way you would for a local host. What problem are you having? What does your code look like?

Use "Insert ActiveX control" and choose GridCtrl.

OR

Use Chris' Grid Control[^]
