Re: CEdit set it to invisible and visible

Do what Chris said, it's the easiest and most correct way to do it.

myEditCtrl.ShowWindow(SW_SHOW), myEditCtrl.ShowWindow(SW_HIDE)

myEditCtrl.ShowWindow(SW_HIDE) & myEditCtrl.ShowWindow(SW_SHOW) does not work either. Is there a limitation with Visual Studio 6.0?

Wow - I've been trying to answer this since you posted it. CP is SO slow at times...

I just did a dialog app in VC6, and added an edit and a button, the button does this:

void CDialogTestDlg::OnButton1()
{
m_Edit.ShowWindow((m_bState) ? SW_HIDE : SW_SHOW);
m_bState = !m_bState;
}

Works like a dream. Have you verified that your SW_HIDE/SW_SHOW code is being called ? Is it being called AFTER the control is created ? Is your variable pointing to the right control ?

Set a breakpoint (F9 and it will stop there when you run in debug mode ), or

AfxMessageBox("Here I am, isn't it peachy ??");

Just below the line.

Christian,
Thanks for all of your help! I made sure the control is created before I make this call. But, still not working.

I am headed out for the evening, but will try your suggestion later tonight.

Thanks again!

It's bound to be something simple. I'd suggest following my steps, create a dialog app, with an edit and a button, set up a bool and insert the code I posted. Then work backwards to figure out what is different in your code.

Good luck !!

Is the there a way to change a project which was originally created to dynamically link to statically link to the MFC. TIA

You may also need to select project, settings, c++, code generation (from memory) and make sure that the C runtime is also statically linked.

Cheers,

No need, when you change the MFC link type, it automagically changes the CRT link type as well.

This isn't a programming question per say, but I didn't really know where else to post it.

I see a lot of people who use the icons from the Visual Studio.net IDE in their projects on here and I'm just wondering if anyone knows where to get them from. Are they included with Visual Studio.net? Are they downloadable?

thanks.

OnPaint question..

Hello,
I am trying to paint a simple yellow border around my CRichEditView.. I tried the following and it paints the border but nothing inside.. Can anyone give me some help, I'm a newbie when it comes to Custom painting.

void CMyRichView::OnPaint()
{
        CPaintDC dc(this);
	
	// DRAW A YELLOW BORDER AROUND OUR RICH EDIT CONTROL.
	CRect border;
	GetClientRect(&border);

	dc.FillSolidRect(0,0,1,border.bottom, RGB(255,255,128));	
	dc.FillSolidRect(0, 0, border.right, 1, RGB(255,255,128));	
	dc.FillSolidRect(border.right-1, 0, 1, border.bottom, RGB(255,255,128));	
	dc.FillSolidRect(0, border.bottom-1, border.right, 1, RGB(255,255,128));
}

Thanks,
Rob

You fill a rectangle with color, the actual inside of the control is masked by the filling.
OnPaint will paint the client area of the control. I suggest you paint in the OnNcPaint.

Thanks for the post.. I have tried this with no success..

LRESULT CMyViewView::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) 
{
	if(message == WM_NCPAINT)
	{
		CClientDC dc(this); //  TRIED CPaintDC dc(this) too... 
		
		// DRAW A YELLOW BORDER AROUND OUR RICH EDIT CONTROL.
		CRect border;
		GetClientRect(&border);

		dc.FillSolidRect(0,0,1,border.bottom, RGB(255,255,128));	
		dc.FillSolidRect(0, 0, border.right, 1, RGB(255,255,128));	
		dc.FillSolidRect(border.right-1, 0, 1, border.bottom, RGB(255,255,128));	
		dc.FillSolidRect(0, border.bottom-1, border.right, 1, RGB(255,255,128));

	}
	
	return CRichEditView::WindowProc(message, wParam, lParam);
}

If I use CClientDC the border doesn't show but the document shows.. If I try CPaintDC the border shows but nothing inside the border (document doesn't show)..

Adding this to the bottom seemed to fix my problem...

InflateRect(border,-1,-1);
RedrawWindow(border,NULL,RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE);

CString parsing

Hey all I need some "C++ 101" help,

I am working on a function that reads in a string and converts it into a CTime, using atoi( ) Confused | :confused:

. The function declaration is
bool ConvertTimeStr(const CString& TimeStr, CTime& Dest)

any suggestions on how I can convert a string such as "12:00:00" into 12:00:00

The quoted article will help I'm sure, but I have found the following 2 approaches to be useful, alone or in combination.

1) The MFC COleDateTime class provides some string parsing capabilities, and you can then check the GetStatus() return code.

2) Alternatively, you could try something like:

bool ConvertTimeStr(const CString& TimeStr, CTime& Dest)
{
int hh, mi, ss;
char ch;
// ch catches junk beyond end of string
if (sscanf(TimeStr, "%d:%d:%d%c", &hh, &mi, &ss, &ch) != 3)
return false

// now check for valid days of month etc.
// The MFC classes can be used to do this.
return whatever!!
}

...

I have a Visual C++ 6 application.

When I run this application in the Visual C++ IDE
and I end the application I will get an "Unhandled Exception in server.exe (NTDLL.DLL): 0xC0000008: Invalid Handle." error.

But when I am running only the exe without the IDE there is no error!

What's the reason?
