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
Everything's beautiful if you look at it long enough...

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)
{
UINT hitResult = CDialog::OnNcHitTest(point);
if(hitResult == HTCAPTION)
return HTNOWHERE;
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)
{
UINT hitResult = CDialog::OnNcHitTest(point);
if(hitResult == HTCAPTION)
return HTNOWHERE;
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;)

you can try activeskin software .its very easy to modify any shape of window, toolbar, button and many more. its support visual basic and visual c++.

ok,
Thanks for the answer, but I would like to do it the hard way. Somebody wiser than me said that it's the best way to learn 
Regards

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!

Hello,
Where can I get MS DataGrid control?
I am using Visual C++ 6.0 Introductory Edition? I don't have DataGrid control in the list of registered ActiveX controls?
Can I download it from somewhere?

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.

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".

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!

Hi i would like to know how to open a folder, from hitting a button on a dialog wizard/app.
What i want to achieve is this:
This wizard i want to create will create a file which is needed by a 3rd party program. What i want to do is once the button is pressed which creates the new folder, i want to press another button which will open up the folder where that new file was created. I dont ned to know how to create buttons etc. Its just how do i open a normal folder from clicking on a button?
Any ideas?
kind regards

What do you mean "open" a folder? If the program creates a file in a specific folder and that folder does not exist, then the program should loop through the full folder path and create each folder accordingly beginning at the parent folder, i.e. "C:\"

The folder already exists and the file that gets created is placed in that existing folder. All i want is to be able to click a button on the wizard to display that folder without having to manually open it by double clicking icons until i get to the folder to display the file.

I'm having trouble passing a pointer to and array. I've created a class that has and array of 10.
CString pArray[10];

Is this right?
Then in my calling function I'm not sure how to handle this pointer. Any suggestions?
Thanks
