As I know, the scroll events for rich-edit control are EN_HSCROLL and EN_VSCROLL. In order to allow these notifications, you have to set a mask in dialog’s OnInitDialog:

m_edtMsg.SetEventMask(m_edtMsg.GetEventMask() | ENM_SCROLL);

In addition the scroll bars should be enabled in the Properties panel.

If you want to change the colours of scroll bar, I think you can try the WM_CTLCOLOR or WM_CTLCOLORSCROLLBAR notifications.

If you create your own scroll-bars (for instance, derived from CScrollBar) and put them near the edit control, then the scroll notifications will be WM_HSCROLL and WM_VSCROLL .

When I display the properties of a file using Explorer,
there is often a "Summary" tab, containing information
such as Title, Subject ...

How can I read and write those properties with VC++

Thanks for any help.

This is fine for a doc file, but it does not work for a "normal" text file.
I created a file using Notepad, and used Explorer to change the summary. I want to copy the summary information from one text file to another.

When I used the example given by Microsoft in
http://support.microsoft.com/kb/186898/EN-US,
it worked for a doc file, but complained that the text file was not a compound file.

Sure it does. Just use StgOpenStorageEx() instead.

I think it is better to derive a class for the button from CButton and override DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct).Here u can draw the button, and can give color u wanted to your button.

I like to autosize the owner draw button depending upon the text that it load dynamically based on localization strings. so some strings are large than others. Keeping this I override DrawItem in the inherited class from CButton. (In below i tried unconditionally to increase the size at runtime, once it is achived, i think i can go ahead for resize code)
The sample code is below

void CMyGraphicButton::DrawItem (LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CString cs;
CString cslong;
ASSERT(lpDrawItemStruct->CtlType == ODT_BUTTON);
LPCTSTR lpszText = (LPCTSTR) lpDrawItemStruct->itemData;
if (!lpszText || lpszText == (LPCTSTR)-1)
{
GetWindowText (cs);
}
else
cs = lpszText;

// now i m trying to resize , so let try to increase the size of button unconditioally
// I get
//lpDrawItemStruct>rcItem.left =0
//lpDrawItemStruct>rcItem.right =75
//lpDrawItemStruct>rcItem.top = 0
//lpDrawItemStruct>rcItem.bottom = 25
//As my button is on extreme right side of dialog so i tried to extend/increase the size of
// button of the left side as follows

lpDrawItemStruct>rcItem.left -= 25 ;

// but the above causes the text to be moved on right side insead of resize/increase the
//button size.

Any idea or help is appriciated.

Thanks
Anil

As tox said, if you don't get answers here, it's because noone knows about BREW here.

Maybe you should try the forums at Qualcomm instead? It seems as the obvious place to discuss BREW problems.

This is overkill. Drop the USES_CONVERSION macro and just use this:

img = Image::FromFile(L"C:\\0.bmp");

What is it? What are you doing that causes this? Is the dialog modeless or modal?

Tell us what the error is, then we might be able to help you. An assertion shows up to tell you that something went wrong. There is in general an indication of what went wrong. We cannot guess from what it is.

A tip that will help you a lot: learn to use your debugger ! You cannot even imagine how helpfull it is once you feel confortable with it. You can use the callstack to see from which function (of yours) the problem could come.

If you see a system dialog box with Retry or Break button, then click on that button, and then go to Call Stack panel (from menu: Debug --> Windows --> Call Stack) and see the history of last functions that were called before the error. This information can be useful.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
