Hi I'm trying to reposition like so:

void CForm2View::OnSize(UINT nType, int cx, int cy)
{
CFormView::OnSize(nType, cx, cy);
m_editbox1.MoveWindow(0,0,cx,cy,TRUE );
}

except that I modified the code at
http://www.codetools.com/docview/centermdiwnd.asp
to make the CFormView fit exactly and immovably in my MDI frame (took away draggability of the view as well).

The above is causing a debug assertion.

The foll shows the messagebox but doesnt like setwindowtext either:
void CForm2View::OnSize(UINT nType, int cx, int cy)
{
CFormView::OnSize(nType, cx, cy);

//MessageBox("aaaa");
// m_editbox1.MoveWindow(0,0,cx,cy,TRUE );
m_editbox1.SetWindowText ("moving!!");

MSDN says:

Example
// Resize the list control contained in the view to
// fill the entire view when the view's window is
// resized. CMyView is a CView derived class.
void CMyView::OnSize(UINT nType, int cx, int cy)
{
CView::OnSize(nType, cx, cy);
// Resize list to fill the whole view.
m_List.MoveWindow (0, 0, cx, cy);
}

So I am confused. Please respond! Confused | :confused:

I see...
The problem is that OnSize() is call a first time when the view is created.
I tested that with a simple dialog based containing a button...
And it's OK...

bool m_bWait => a member of CMyDialog (which is a CDialog derived class)
CButton m_ctrlButton => a member of CMyDialog

class CMyDialog : public CDialog
{
public:
CMyDialog(CWnd* pParent = NULL) {
...
m_bWait = false; // initialize in the construtor
}
...
}

void CMyDialog::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);

if(m_bWait)
m_ctrlButton.MoveWindow(0, 0, cx, cy, TRUE);

m_bWait = true;
}

I hope that can help you Big Grin | :-D

Yuck. Much better to do this:

void CMyDialog::OnSize(UINT nType, int cx, int cy)
{
CDialog::OnSize(nType, cx, cy);

if (::IsWindowVisible(*this))
m_ctrlButton.MoveWindow(0, 0, cx, cy, TRUE);
}

Thank you very much. Your approach works, and I also ran into http://www.codeguru.com/mfc/faq/comments/485.shtml, so the issue is resolved. Much appreciation for your testing!

HTREEITEM positions

I have a CTreeCtrl. There are many many children of the root, and many children of those children and many children of those children and so on. I was wondering if there is a way to find out which position that a selected item is at. I currently get the parent of the parent of the parent and so on until I get a NULL. Is there an easier way?

Something like this:

bool CCyberPC::ShutDown(LPCTSTR szMsg, bool bReboot)
{
if( m_strComputerName.IsEmpty() )
return false;

CString msg;
if (szMsg)
msg = szMsg;
else
msg.LoadString(IDS_SHUTDOWN);

BOOL bResult = InitiateSystemShutdown(
(LPTSTR)(LPCTSTR)GetPCAddress(),
(LPTSTR)(LPCTSTR)msg,
10,
TRUE /*bForceAppsClosed*/,
(int)bReboot
);

return bResult ? true:false;
}

Hope this helps.

That's work for my own PC (locally thus) but when I use it to another IP adress (from my network) that doesn't work : bResult is false...
I think that comes from Privilege, but I'm not sûr.

Visual Studio Suidical

For the last week or so, my Visual Studio 6.0 decides to shut itself down in the middle of a debugging session. Both the VS and the program I'm debugging gets killed instantly and I'm looking at my wallpaper all of a sudden. Had this ever happened to anyone ?

Funny thing is the exact same thing happened to a co-worker today.

Coloring upto the light blue lines in a CDialog

DanYELL12-Jul-02 9:18

I have an aboutBox. It's a simple CDialog we all
know and love.

I can color the background of the aboutBox using
OnCtrColor(). In the resource editor, I notice
faint, light blue lines that surround the aboutBox with about a half-inch indentation. I
saw in a program the other day white background
coloring up to those blue lines, then the
standard grey that surrounds it and a border. How
can you make it fill the background of a CDialog
up to the light blue lines?

Please, any response anyone can give me will be
greatly appreciated. I tried changing various
settings in the dialog resource, but nothing
worked.

Sincerely,
Danielle (an overworked graduate student)

DataSet()

I read the article N-Tier application using Managed C++ and ASP.NET - A Tutorial
By Ranjan Banerji
that can be found at the address: http://www.codeproject.com/dotnet/N_Tier_Web_Service.asp

Everything worked smoothly, and it introduced me very well on the web-services with SQL world.

What I want to know is how I can build a client using C++.
How I manage the data in the DataSet?

The function in the WebService returns a DataSet, how I get the data out of it and fill, let's say, an edit control with those data?

Thx!

Urgent!!!positioning controls on a CFormView MDI

ns12-Jul-02 7:51

12-Jul-02 7:51

This is frustrating. I want my controls to be in certain places so I eyeball them and place them on the form. Now when I run the MDI project, these controls dont show up exactly as I placed them and theres all sorts of spaces that I dont want. For example, I want an oK button at the very right hand edge of the form. I draw it there. But its shifted inward (by a lot!) when it runs. So my designtime layout doesnt look like the runtime layout. I need to get a grip on this urgently.
Thanks in advance

some relevant info

ns12-Jul-02 8:30

12-Jul-02 8:30

I used Brian harts code (modified) to make the CForm dialog fit the frame and resize with it . Its here in code project. I suspect that I have to some coding to keep my controls at their design time locations. I thought i'd create them dynamically with the constructor and create and all that so i can position them , but I'm not sure what to fill the rect structure with so they move along with the frame.

any ideas?

Use ResizeParentToFit(FALSE) in the OnInitialUpdate handler of your views.

I am missing the point. I want the mainframe to be 800 600 pixels on the screen when the app starts up. I am happy with the fact that my CFormView fits exactly. Confused | :confused:

Re:I got it!

I think I have to do d=something like:

// Size the window to 1/3 screen size and center it
cs.cy = ::GetSystemMetrics(SM_CYSCREEN) / 2;
cs.cx = ::GetSystemMetrics(SM_CXSCREEN) / 2;
cs.y = ((cs.cy * 2) - cs.cy) / 2;
cs.x = ((cs.cx * 2) - cs.cx) / 2;

Thanks.

Icons??

Hi All. I'm building an app that graphs data and am looking for clean, professional, 3d-looking icons. I tried making my own in Photoshop, but they turn out kind of cheesy. Icon art seems to be somewhat of a mystical talent. I've searched the Internet far and wide to no avail. Most of the stuff I found was cheesier than what I made myself. (and that doesn't speak for much) The tools will include Zoom, Autoscale, Statistics, Overplot, Calculator, and all kinds of data smoothing FFT and signal manipulation. I am always searching for that elusive little detail that embellishes the sweet smell of professionalism, and any suggestions will be greatly appreciated.

~tia!
