Visual Studio Pointer Help..

I don't know what the proper terminology for it but I am trying to understand why the little popup window that you get when you are dealing with pointers or strctures, sometimes works and sometimes doesn't. Say you have a setup like this:

struct MyStruct {
int iData;
}

MyStruct mystruct;

then when you type
mystruct. <- here you will get the nice little pop up window..

Anyone knows why it doesn't work sometimes and why it does work?? Help please.. I like that little pop up.. I am using VC6.0 with service pack 5.
I am specially having hard time with double pointers and for my first pointers I get that nice little pop up but not for the second one...

This intellisense problem is a well known bug in VS6.0+ - think - and this is a guess only - it has something to do with includes. Not sure.

I don't know if this was the case in VS6 (since I haven't used it in a while), but I have noticed that VS.Net refuses to give the popup if you have a syntax issue preceding the code you are currently typing. I wouldn't really call that a bug though. Now that I've noticed that it happens, when the box doesn't popup I start looking for a missing brace or semi-colon, etc. Kind of helpful in a way.

I know it doesn't really help you with your problem, but just something to look out for.

You are correct. This is what happens with VS6, too. Syntax errors will kill Intellisense in a hurry!

Some times it is caused by an syntax error occuring before the current point.
Some times the information is just not available yet (try recompile).

Trust in the code Luke. Yea right!

Hi,

Is there a way to create a modeless dlg that we cannot move so that it always remains at the same place that I have created it?

Thanks

You can easily do this via your dialog's OnWindowPosChanging() method. When the modeless dialog is created, save it's window rect to a member variable. Then in OnWindowPosChanging(), change the 'x', 'y', 'cx', and 'cy' values of the WINDOWPOS structure.

BEGIN_MESSAGE_MAP(CModelessDlg, CDialog)
//{{AFX_MSG_MAP(CModelessDlg)
//}}AFX_MSG_MAP
ON_WM_WINDOWPOSCHANGING()
END_MESSAGE_MAP()

BOOL CModelessDlg::OnInitDialog()
{
CDialog::OnInitDialog();

GetWindowRect(m_rect);

return TRUE;
}

void CModelessDlg::OnWindowPosChanging( WINDOWPOS* lpwndpos )
{
lpwndpos->x = m_rect.left;
lpwndpos->y = m_rect.top;
lpwndpos->cx = m_rect.Width();
lpwndpos->cy = m_rect.Height();
}

This is another way to do it. To move the dialog the user should drag the dialog caption. you can override the WM_NCHITTEST message and disable the HTCAPTION result from reaching hte system.
the could should be like this

UINT CMyDlg::OnNcHitTest(CPoint point)
{
	//Store the result returned by the dialog's WinProc    
	UINT hitResult = CDialog::OnNcHitTest(point);
	//if the mouse is in the caption bar change the result to HTNOWHERE
	//so the system wouldn't recognize it
	if(hitResult == HTCAPTION)
		return HTNOWHERE;
	//any other result should be returned as it is
	return hitResult;
}

There is another simple way to do it.
To move the dialog the user must drag the caption bar, thus you can override the WM_NCHITTEST message and disable the system from recognizing that the mouse is in the caption bar. This code shows ho that is done:

UINT CMyDlg::OnNcHitTest(CPoint point)
{
	//store the value returnd by the WndProc	
	UINT hitResult = CDialog::OnNcHitTest(point);
	//if the mouse is in the caption bar, change the result to HTNOWHERE
	//so the system does not recognize that the mouse is in hte caption
	if(hitResult == HTCAPTION)
		return HTNOWHERE;
	//any other result mus t be returned as it is
	return hitResult;
}

If the dialog has a system menu the keyboard can be used to move it, so this isn't good enough. OnGetMinMaxInfo() may do the trick.

Hi,

Here is my problem. I want to give a non-rectangular shape to my dialogbar. So I created a dialog ressource, a CDialogBar derived class and I created my dialog into my CMainFrame class.

In my CDialogBar derived class, I overide OnCreate():

int MyDlgBar::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialogBar::OnCreate(lpCreateStruct) == -1)
return -1;

// Create a 'CRgn' object
CRgn rgn;
CRect rect;
GetWindowRect(&rect);

rgn.CreateEllipticRgnIndirect(&rect);

// Set the windows region
SetWindowRgn((HRGN)rgn.GetSafeHandle(), TRUE);

// Detach the 'CRgn' object from the region or else the
// 'CRgn' destructor would close the 'HRGN' handle when 'rgn'
// goes out of scope
rgn.Detach();

return 0;
}

The problem is that I can see the shape that I wanted, but the areas where I'm suppose to see the App Background, are not refreshed. I see my desktop unstead.

any ideas?

Thanks;)

One possible solution is to draw to the non-client area before your dialog bar is drawn. This could be done by the parent or you could get the DC for the parent and then fill in the area before drawing your dialog bar.

The problem you are having is do to the fact that Windows (or MFC) thinks your dialog bar is rectangular and, therefore, is avoiding drawing the same area twice.

Good Luck!

Best Software For Printing Out Code

What's a good software package for printing out code?

I was just handed a large project written in VC++ IDE, and asked to find and analyze a few algorithms in it. I'd like to start by printing it (you know why -- so I can spread it out and look at lots of code sections at once). But I really dislike the way VC++ prints code, which doesn't look anything like what it displays on the screen (no colors, different font, etc.) Moreover, it looks like I would need to make a selection of each and every file that I want to print, which seems silly since I want them all.

Can anyone recommend a good software package? I have a color printer, and would really prefer formatted printout in color.

Our programmer's editor, ED for Windows does color syntax highlighting to color printers. You can just print a selection etc.

I'd also suggest having a close look at its Source Database capabilities which provide excellent code navigation around large complex projects, especially if you are unfamiliar with the code base. There is also a very good multithreaded Find in Files and .... See the "Top 11 Fetaures" list and screen shots on our Web site for a quick overview.

ImageList_Read & ImageList_Write functions...

Guy Lecomte13-May-03 5:37

13-May-03 5:37

Hi,
I need those 2 functions : ImageList_Read & ImageList_Write functions... It seems they already exist in comcntl32 . More of this I’ve found this code :
In Winctrl2.cpp

#ifndef _AFX_NO_OLE_SUPPORT
extern "C"
{
HIMAGELIST WINAPI ImageList_Read(LPSTREAM pstm);
BOOL WINAPI ImageList_Write(HIMAGELIST himl, LPSTREAM pstm);
}
#endif
…

BOOL CImageList::Write(CArchive* pArchive)
BOOL CImageList::Read(CArchive* pArchive)

This is what I need but I’m unable to use it because it is in a #ifndef _AFX_NO_OLE_SUPPORT compilation condition. So, I don’t know how I can access it.
What is the #ifndef _AFX_NO_OLE_SUPPORT for? Where does it come from?
I really need ImageList_Read & ImageList_Write or BOOL CImageList::Write(CArchive* pArchive), BOOL CImageList::Read(CArchive* pArchive)

Can anybody help me please? Is there a sample project somewhere that uses the ImageList_Read & ImageList_Write functions?
Thank you very much in advance.

Best regards

Hi,
I have troubles with CRecentFileList.
I want to manage the Recent Files manually if I do an "Open" or a "Save As" in my SDI-Document.
My RecentFileList has the ID "Hi,
I have troubles with CRecentFileList.
I want to manage the Recent Files manually if I do an "Open" or a "Save As" in my SDI-Document.
My RecentFileList has the ID "ID_FILE_MRU_FILE1" in my menu "ID_MAINFRAME".

This is my code, which I call at an "Open" or a "Save As":

void CMainFrame::setMRU(CString File)
{
CRecentFileList* m_pMRU;
m_pMRU = new CRecentFileList( 1, _T("Software\\tsSoft\\nm\\MRU"), _T("File#%d"), 4 );
m_pMRU->ReadList();
char* a = (char*) malloc(File.GetLength()+1);
sprintf(a,"%s",File.GetBuffer(File.GetLength()));
//MessageBox((*m_pMRU)[0]+"Pferd",(*m_pMRU)[0],MB_OK);
//MessageBox((*m_pMRU)[1]+"Pferd",(*m_pMRU)[1],MB_OK);
if( File.GetLength()>0 ) m_pMRU->Add(a);
m_pMRU->WriteList();
// Eintrag suchen und überschreiben
CCmdUI* cmdUI = new CCmdUI();

break;
}
}

What is the problem with it?
I got 2.

First, I can't see my Files in the registry at "Software\\tsSoft\\nm\\MRU" and I don't know why and second I got an Assertion-Error at "m_pMRU->UpdateMenu(cmdUI);"

It will be very nice, if someone can help me to solve my problem!
