it's merly an Microsoft Specific Typedef

"The maximum size for an array is defined by size_t. Defined in the header file STDDEF.H, size_t is an unsigned int with the range 0x00000000 to 0x7CFFFFFF."

evt have a look here..

size_t isn't Microsoft-specific, it's part of ANSI/ISO standard C. It's defined in <stddef.h> and it's the type returned by the sizeof operator.

You sure about this, behaps im missing something Well it wont be the first time then.. Smile | :)

But if you take a look at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_clang_Array_Declarations.asp
They say it's MS specific.. or is it another issue they are adressing here..??

Hmm...

size_t is a standard type. The range of a size_t is compiler-specific, however.

SOAPCLIENT_SEND_ERROR and ERROR_IO_PENDING

I'm trying to access XML Web Service using C++ and I've got two

problems.

First, when I try to invoke web service's method from another thread

(not UI thread) I get SOAPCLIENT_INITIALIZE_ERROR error.

Second, when I pass to web service BLOB data which length is greater

than approximately 800KB I get
ERROR_IO_PENDING error (returned by GetLastError).

Is there any way to invoke web service's methods in worker threads and

to pass in BLOBs that are larger
than 800KB (C# client can send about 3MB)?

if (pMsg->message == WM_KEYDOWN)
{
then wParam is the keycode
}

IMO, OnKeyDown or OnChar is a nicer way to handle most keystroke actions.

I want to do it in FormView and OnKeyDown and OnChar didn't work there so I have to ovverriden Pretranslatemessae.

Anyway,thank you.

LVM_SORTITEMS

Hi,
I got a Listview control which is ownerdata driven. I want to sort it but the LVM_SORTITEMS function just fails... I am not sure if it's relevant, but the GetLastError() return that the params are invalid. I checked it 20 times, the compare function is all right (CALLBACK, right params, return... all). I tried passing both NULL and some dummy to as the LPARAM (though it shouldn't ake any difference cause I don't do anything with them later). The HWND is valid and is used before and after this piece of code. The only thing that comes on my mind is that sorting isn't supported with ownderdata, but I haven't found a single line regarding this...

Thanks!

It is supported with CListBox.

With CListBox an owner-drawn list box created w/ style LBS_SORT and items are added to it w/ AddString, then CListBox::CompareItem must be overridden with a version that compares two arbitrary items packaged in COMPAREITEMSTRUCT structures.

I am a little usure of how to do this. I want a function to run after the user slides to a new position. It would be nice if it ran at every instant of the slider movement. This function ses the brightness and it would be nice to see it brightening smoothly as you slide. How to I tie my slider which is in the toolbar, to this function? It has a varaible m_slider of type control.
Thanks,
ns

Well,(my slider is in the toolbar. I added it by Create -ing a CSliderCTRl in mainframe class)
I tried this:

void CMainFrame::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
// TODO: Add your message handler code here and/or call default

CSliderCtrl* pSliderCtrl;

pSliderCtrl= (CSliderCtrl*)pScrollBar;

int x = pSliderCtrl->GetPos();

CString s;
s.Format("%d",x);
AfxMessageBox(s);

CMDIFrameWnd::OnHScroll(nSBCode, nPos, pScrollBar);
}

I only have one slider m_slider, which I didnt know how to put into the above code.

When I slid, the execution didnt go into the function above. My slider is in the toolbar. Actually, though I added the slider in the toolbar via the mainframe class, I really want it to execute a function that belongs to my view class, when I slide it.SO

1. What am I doing wrong (need to involve m_slider somehow? )

How to get the view function to run if I slide?

Thanks,
ns

If I put a slider on the view form, then this works:

void CSliderctrlView::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) 
{
	// TODO: Add your message handler code here and/or call default
	
	CFormView::OnHScroll(nSBCode, nPos, pScrollBar);

	int nPos1  = m_sl1.GetPos();
	CString temp ;
	temp.Format(" the position is %d ",nPos1);

	AfxMessageBox(temp);

}

But
1. My slider is a mainframe variable, and exists in the toolbar.

It doesnt respond to WM_HSCROLL trapped by the mainframe class. When I did the Add windows handler, the filter (right hand bottom) was set to "TopMost frame".

When I added the handler to the view class, the filter was "window"

Looks like I need to do something special to trap hscroll in the toolbar....but what? ??

Confused | :confused:

ns

Your slider will send it's messages to the toolbar, so you have to relay it from the toolbar to your view.

void CMyToolbar::OnHScroll(UINT code, UINT pos, CScrollbar *pBar)
{
    CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
    CMDIChildWnd *pChild = pFrame->MDIGetActive();
    CView *pView = pChild->GetActiveView();
    pView->SendMessage(WM_HSCROLL, MAKEWPARAM(code, pos), (LPARAM)pBar->GetSafeHwnd());
}

Qusetion about sendmessage...

ns31-Aug-02 11:26

31-Aug-02 11:26

New to sendmessage. I see youre sending WM_HScroll to the view. That clear. Now shall I put a handler for this in the view class? And within it call my function? What if some other scrolling operation happens, like when I scroll the mainframe or the view? I dont want the custom function to run then, which it will since I'm trapping all HScroll stuff.....How do I restrict the WM_HSCROLL handler of the view class to run only when I slide the slider?

Thanks,
ns

Check the value of the pScrollBar pointer passed into your view's OnHScroll() handler. It will be NULL if the scroll message was generated by the view's own scroll bars, otherwise it will point to the control that generated the message (the lparam value in the SendMessage()).

The slider control will send its messages to it's parent window, which in all likelyhood will be the toolbar, not the mainframe.

Check out these articles, they may be of some help.

In the second link, he has a docking toolbar. By defaut its showing up at the bottom of the MDI app, near the status bar> i want it to be near the top toolbar, docked in the remaining space alongside it (my custom toolbar has two controls in it). How do I get this to happen? It looks pretty awful sitting at the bottom...

My mfc mdi app has 15x15 or 16x16 toolbar button pictures in it. I'm looking for this size picture for Brightness and Contrast functions. I usually cut and paste from the customize toolbar menu.
Any links or know where I can get it? If its in an ico file, I dont know how to grab it and paste it on the button.

Thanks,

Why not grabbing such common pictures from other apps? Common icon pictures are not copyrighted. Make a screenshot (press the Print key on your keyboard), paste into a new Paint bitmap, use Zoom, copy the icon and paste it in MsDev.

I found out how to adda combobox to the toolbar. so its the same to put in a generic class in the toolbar - say a slider. I really want a spin-edit buddied up pair in the toolbar. How do I insert that? I am referring to http://www.codeproject.com/docking/toolbarcombo.asp?

If I cant figure this out I'll have to use a slider which I'd rather not, because it mnight not look so good if its not dockable separately, ....

Any links or ideas?
