hai all,
I am doing a project in MFC involving graphics.
I used pointerlist to add all the elements(line ,rectangle
or ellipse) drawn on the screen.
And,I redraw(refresh) all the elements in the pointer list,
while drawing a new element.
When more elements are added,the drawing gets very slow.
Is there any way to avoid this slowness without affecting the
previously drawn elements?
Plz help me.
With thanks,
arun chakaravarthy

Just
using namespace System.Text.RegularExpressions;
and add reference System.Text.dll through project or
through code
#using <System.Text.dll>
and I suppose you have start up your project as .NET app in C++.
If you are not you will need to include
#using <mscorlib.dll>
#using <System.Text.dll>
and set your project setting to support clr.
and etc....

No news is good news, it means the mail did'nt bounced back, so the address should be ok ( have you checked on the web sites or other documentations ? ) Also, you might not be the only one trying to contact them by email, and it can take a while; I don't think most of them use "read-receipt"
I think most US universities use .edu, not .edu.us

hi all
i set up a right to left menu in my language for my application. but the items are not right aligned. it seems to be a bug in calculation of their widths:
http://home.morva.net/hamidi/menu-ye_kharab.gif
because when i use a fixed width font for menus in Appearance section of Desktop Properties, the problem gets fixed.
anyone has an idea or knows a workaround?
thanx

How are you creating your window?

eh ??? in english please
im delcaring it how it is in msdn
OPENFILENAME ofn; // common dialog box structure
char szFile[260]; // buffer for file name
HWND hwnd; // owner window
HANDLE hf; // file handle
// Initialize OPENFILENAME
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
// ofn.hwndOwner = hwnd;
ofn.lpstrFile = szFile;
//
// Set lpstrFile[0] to '\0' so that GetOpenFileName does not

//
ofn.lpstrTitle="Select CMIS Student Datafile";
ofn.lpstrFile[0] = '\0';
ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFilter = "Microsoft Access Files\0*.mdb\0All\0*.*\0";
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrInitialDir = NULL;

Let me reformulate the question:
You are creating an application.
Are you using Direct Win32(CreateWindow) or MFC?
In either cases:
Win32 :
hwnd = CreateWindow(...
ofn.hwndOwner = hwnd;
MFC :
CWnd* pWnd = AfxGetMainWnd( );
if(pWnd)
ofn.hwndOwner = pWnd->m_hWnd;

Because hwnd is not a valid window handle.

Where can I find a sample or documentation on ActiveX controls for use from MSAccess Forms.
I am trying to create an activex contol (SysListView32 derived) and trying figure what interfaces should I implement to bind it properly, provide a datasource for the items, etc.
Thanks in advance.

Hi friends,
Currently i am developing one graphical application. The drawing tools like Rectangle, Ellipse, Freehand are kept in a toolbar. My intention is to display the toolbar whenever the user move the mouse to top zone of the client area and hide the toolbar whenever the user move the mouse away from the topzone. I constructed toolbar using Dialog Bar. But i don't know how to place the Dialog Bar in the view window.
Please help me regarding this.

I've never heard the term network patches before. In the general sense, a patch is a piece of code added to software in order to fix a bug (between two releases). You've no doubt heard of an OS patch, which could include, among other things, fixes for network-related components.

So what does the third thread do? In any case, I would be inclined to use PostMessage() for communication between them.

I have a dialog with about 15 edit controls.
The controls are a subclass I've made of CEdit, CMyEdit for the matter.
2 out of the 15 CMyEdit controls don't have their OnNcPaint override called, for no apparent reason. all edit-boxes are declared the same way in the resource-editor, no special handling of any of them not in resources nor in code.
I've tried overriding OnCreate, OnNcCreate (added ON_WM_XXX ofcourse) and Create itself but none of them are ever called.
What am I missing out ?
p.s. - what I need is a 'point of intervention' during the creation/post-creation of the edit-control during which the control is already sized and positioned correctly.

You have most probably made some silly error. Check and recheck! You will want to make sure they are attached to the correct kind of variable in the h-file, and that the resource IDs don't clash.

Perhaps PreSubclassWindow?
