POINT lastDrag

OnMouseDown
{
lastDrag = CurrentMousePosition (should be a parameter passed in to the event handler, but not this name )
}

OnMouseMove
{
POINT moved = lastDrag - CurrentMousePosition
lastDrag = CurrentMousePosition
::SetWindowPos(NULL, currentX + moved.X, currentY + moved.Y, 0, 0, SWP_NOSIZE | SWP_NOZORDER)
}

This is pseudocode.

Here's the solution: http://www.codeproject.com/csharp/CustomForms.asp[^]

Point mouse_offset;

.._MouseDown(..., System::Windows::Forms::MouseEventArgs * e)
{
mouse_offset = Point(-e->get_X(), -e->get_Y());
}

.._MouseMove(..., System::Windows::Forms::MouseEventArgs * e)
{
if (e->Button == MouseButtons::Left){
Point mousePos = this->get_MousePosition();
mousePos.Offset(mouse_offset.X, mouse_offset.Y);
this->set_Location(mousePos);
}
}

C++ 5.0 and displaying Chinese characters

I am having a difficult time convincing DevStudio 97 to accept and display Chinese character fonts during program time. When I run the exe the Chinese characters display fine, but only at runtime. I have been through all of the necessary steps with WinXP and the problem lies solely within Studio97 and C++. Does anybody have any ideas or suggestions specific to C++ 5.0 or Studio 97 that I am missing?

I have:
1) Installed/enabled East Asian fonts (XP)
2) Enabled various keyboard layouts applicable to the desired font (XP)
3) Installed appwzchs.dll
4) Set C++ resource files to default to ChinesePRC
5) Defined _Unicode
6) Entered WinMainCRTStartup as entry point in project settings

I am using PinYin IME.

I may be forgetting something here, if so I apologize. Any help, suggestions, critiques, ideas, etc. will be GREATLY APPRECIATED!!

You are in the wrong forum. This is the C++/CLI forum (the C++.NET forum). Perhaps you should be asking in the Visual C++ forum.

I want to be able to get buddy lists from MSN Messenger. I wrote a little bit of code in C# that does that but I need to rewrite this in C++. I made a new new MFC dll project ( its supposed to be that way ) and added a reference to MessengerAPI. I cant seem to access the API in the same was as the C# code.

I am completely new to C++ so any help will be appreciated.

public ArrayList GetBuddyList()
{
        MessengerAPI.Messenger msgr = new Messenger();
	IMessengerContacts contacts;

	ArrayList retlist = new ArrayList();
	int i, j;

	i = 1;
	j = 1;

	msgr.AutoSignin();

	groups = msgr.MyGroups;

	foreach (IMessengerGroup group in groups)
	{	
        contacts = group.Contacts;

		foreach (IMessengerContact contact in contacts)
		{
			if ( contact.Status == 2 )
			{
				ContactItem item = new ContactItem( contact.SigninName, 
					contact.FriendlyName );
				retlist.Add( item );
			}                    
		}
	}

	msgr.Signout();
}

Add managed event handler function in unmanaged code

Hello,
i've inserted a .NET control in a MFC Dialog, i'd like to append functions to the events of the component but when i try to do (for example):

<br />
component1->OnItemMove += new OnItemMoveEvent(this, myFunction)<br />

the compiler gives my a C3363 error, saying that i cannot create a delegate for OnItemMoveEvent from a member of a unmanaged class (the dialog class where myFunction is defined) or a non member function.

Is there a "trick" to use .NET events from my MFC application or i cant do that in any way?

Thank you,
Gianmaria

Storing windows positions in registry???

Hi all,

I'm storing windows positions in the registry - which I can do with no problems. What I'm asking is if there is a way to store two forms of the same type. I obviously can't use the form name as they will be the same. Does the form class provide any attribute that will differentiate between two forms.

for example - I opened two logForms in my application. When I store the positions of the logForms is there any way to set the name element of the reg entry so that I know it's a logForm but I also know that there are two of them.

Hope this makes sense.

Is your main app a MDI? if so then you should think about either using a different class for each logForm or keep track of the enumerated child form by using:

Form* mdiChild[] = this->get_MdiChildren();
for (int x =0; x < this->MdiChildren->Length;x++){
store the form using x
}

there maybe a better way other, but this is what I can only think of.

Remote Desktop post a different display?

I have posted a problem in www.codeguru.com, but no respond so far Frown | :(

My friend told me www.codeproject.com are more active these days... try my luck here.

The problem is drawing a simple MFC circle, will post a different display if you view it locally vs one view it through remote desktop. I'm suspecting this is a remote desktop problem or MFC problem.... can someone confirm or let me know if I miss anything? (it's okay when view through VNC Viewer)

I can't find how to attach document here, so you could click to codeguru to view the description of the problem in more detail

http://www.codeguru.com/forum/showthread.php?t=350088[^]

To be etically correct, do respond using codeproject if you viewed the issue through this forum. Thanks...

That's really weird. What are t he color depths on the two setups ? ( local and remote )

Not sure if I understand what color depths really means. Anyway, both my local and remote desktop is set to 32 bit colors. I tried both (run the application in either machine, and use the other as remote desktop), the problem persist.

color depth is bits per pixel. If both are 32 bit, that's really, really strange.

Hi Christian

How come your title is different. Are you responding to my post on "Remote Desktop Issue"? If yes, thanks... at least someone bother to test it out....especially a Microsoft MVP in C++.

It would be great if you could found any insight to this problem

Thanks! Hmmm | :|

That is because there is no standard way of doing this because there are many different date/time formats. A good choice is to output the string in the format that is default for the user's locale.
