Visual Studio .NET Editor Question! Simple!

2-Aug-02 5:33

Hello All,

Ive finally entered the world of VS.NET. I love the new IDE, but. I work in the UNIX environment a lot, Im a VI guy, but I like the VS.NET IDE better. I have been editing some C files that I am also loading into VI and Ive noticed that there are speecial characters in the file Specifically TABS and carriage returns marked with ^M.
This didnt happen in VC++ 6.0 is there an editor option I can turn off. I just want plain text editing..

Thank you..

Is there any message that is sent when a Tree Control collapses a node? If not then how can I tell when a node has been collapsed?

WM_NOTIFY/TVN_ITEMEXPANDED is sent when a node has expanded or collapsed!

LOL. Wonderful. Oh well. Shouldn't be hard to figure out which one is which. Just a small point though. Would it have been that much trouble to add a TVN_ITEMCOLLAPSED message?

The action member of the NMTREEVIEW is TVE_EXPAND when it is expanded and TVE_COLLAPSE if it has collapsed.

Think about UpdateData(true/false). They could have easily added a UpdateControls(...) but they didn't Smile | :)

Where is MS VRML Viewer ?

2-Aug-02 4:51

Maybe that question seems a bit odd but I've got the MS VRML viewer on a machine and not on the other. So I was wondering how it was distributed.

I'm looking for MS VRML Viewer download area and Interface specifications somewhere on the MS site but can't find any info.
Is the ActiveX control still available separately or has it been included in IE ? Has it been abandonned ?
I'm looking for infos on an HTML compatible VRML viewer that I could use for a professional project. Every link of tips would be appreciated.
Thank you

Dialogs without MFC

Does anyone know if there are any wrapper classes around for using dialogs without MFC. I'm not looking for a full CDialog replacement, but something which encapsulates the WndProc etc.

Visual C++ and Exponential Numbers

I've mapped a variable of type double to an edit box (within a dialog box) in Visual C++ and I want to control the entered value so that it stays fixed(0.001) rather than scientific(1e-003). Is there a way of achieving this?
Cheers.

With DDX_Text mapping, you're probably without any chance. What about going into 'manual' mode and using [Get|Set]DlgItemText?

When you're using ClassWizard for dialog data exchange (ddx), it generates the sequence of calls to DDX_xxx in DoDataExchange. One of these calls corresponds to your double value. If this number is shown with exponent, your only choice is to fix it by setting edit control text 'manually', with a call to SetDlgItemText. This would look more or less like this:

void CYourDlg::DoDataExchange(CDataExchange* pDX)
{
	CDialog::DoDataExchange(pDX);
	//{{AFX_DATA_MAP(CNormalizeDlg)
	DDX_Text(pDX, IDC_EDIT1, m_value);
	//}}AFX_DATA_MAP

	if (!pDX->m_bSaveAndValidate)
	{
		CString strx;
		strx.Format("%f", m_value);
		SetDlgItemText(IDC_EDIT1, strx);
	}
}

You can format your value any way you want before call to SetDlgItemText.

Strange Compile errors

When I made any editing changes to my ado project, randonly it bombs with the foll.errors. There is no going back with "undo". Then I have to make a brand new project, but that gets "corrupted" as well in a matter of a few edits. Has any one seen this? I could just be adding a messagebox!!

Thanks,

I get this periodically with some of my projects. It seems to be a bug in the VC compiler where it somehow gets upset with the input stream. Usually I can get past it by doing a rebuild all.

I had been exploring this class merrily when these errors starting happening. So I abandoned my strategy and started doing ADO from scratch. Now that REbuild All has dealt with the problem, I am almost afraid of trusting it, because if it doesnt go away next time with Rebuild All, I'll have to take up raw ADO and I have just enough time to go the one way - the class or raw ADO. Do you think rebuild all is trustworthy?
