This is the default behavior. You have apparently added code to change that.

As David said this is a default behaviour..
Check all the Edit Controls have the sequence tab position..
Press Ctrl+D, in the dialog during design time to change the tab settings..

Look up the WM_GETDLGCODE and the DLGC_WANTTAB message for details on how to alter the default special handling of the tab key. You may also be interested in the IsDialogMessage API.

How can I get a HBITMAP handle from a CImageList Object?
I have a CImageList Object already. And I want to change it into a HBITMAP.
How could I do so?
Thank you!

Have you seen CImageList::GetImageInfo ?
|
|
|
|
|

See
m_ImageList->GetImageInfo(...);
-----------------------And-----------
You can use From ExtractIcon(index) for get a hicon of list and
draw this icon to a dc and save this dc to a bitmap
this code is an idea maybe its not good but if you want to checking this code its working.
<br />
CImageList* m_ImageList;<br />
CBitmap Bmp;<br />
m_ImageList=new CImageList();<br />
m_ImageList->Create(32,32, ILC_COLORDDB,0,0);<br />
Bmp.LoadBitmap(IDB_BITMAP1);<br />
<br />
m_ImageList->Add(&Bmp,RGB(100,105,0));<br />
m_ImageList->Add(&Bmp,RGB(100,105,0));<br />
<br />
CDC dc;<br />
CBitmap p;<br />
CImage m;<br />
dc.CreateCompatibleDC(GetDC());<br />
p.CreateCompatibleBitmap(GetDC(),32,32);<br />
dc.SelectObject(p);<br />
<br />
for (int i=0;i < m_ImageList->GetImageCount();i++)<br />
{<br />
dc.DrawIcon(0, 0, m_ImageList->ExtractIcon(i));<br />
m.Attach(p);<br />
m.Save("c:\\0.bmp");<br />
m.Detach();<br />
}<br />
<br />
<br />

Thank you very much.
but there is still a problem.
the bmp that saved have a black background.
how could I change the back colour into what ever I want??
And It is much better that you don't use CxImage.

You mean to say, you want to change BMP, is it?

Yes,change the backgroud colour.
change black background into red,for example.
|
|
|
|
|
I'm not sure, if its possible.

Its possible(he needs a little work for it)

ya tru, its more than little.

DrawIcon(you need to calculate x from icons in your listimage,0,m_ImageList->ExtractIcon(i))

void CSaveBmpToFileDlg::GetImageFromList(CImageList *lstImages, CBitmap* destBitmap)
{
CImageList tmpList;
tmpList.Create(lstImages);
IMAGEINFO lastImage;
tmpList.GetImageInfo(0,&lastImage);
CDC dcMem;
dcMem.CreateCompatibleDC(GetWindowDC());
CRect rect (lastImage.rcImage);
destBitmap->CreateCompatibleBitmap (this->GetWindowDC(),
rect.Width () * tmpList.GetImageCount(), rect.Height ());
CBitmap* pBmpOld = dcMem.SelectObject (destBitmap);
for (int i=0;i<tmpList.GetImageCount();i++)
{
tmpList.DrawIndirect (&dcMem, i, CPoint(i*rect.Width (), 0),
CSize (rect.Width (), rect.Height ()), CPoint (0, 0));
}
dcMem.SelectObject (pBmpOld);
}
I got this code. the bmp itself was nice.but still,the back was black

In this example we have a 32x32 and if you calculate x for x for draw function then your problem solve but if you want to get x& y from icons in CImageList see ImageList_GetIconSize(yourlist,x,y) and then insert x to current position in DrawIcon if you test this code and your problem is slove i glad but if you have previous error reply to me

Thank you sir.
I tried to do as what you have said.
the bmp file was saved correctly.
but the background was still black.
I want to change the background into RGB(255,0,255).
How could I do so?
Thank you very much.

for black background dc.DrawIcon(x/*32*/, 0, m_ImageList->ExtractIcon(i)); i used 32x32 for your icons you need to calculate x and y
for change background you can use from:
you need to two CDC objects one for draw icon and another for draw previous dc in new dc(for change color)
1-create two dc(dc1,dc2)and create two bitmap
2-in dc1 you draw icon
3-in dc2 you need to set color for bitmap and draw dc1 to dc2
4-then save this dc
it seems that its hard but when you start to this work its not hard also you can find examples for this purpose in bitmap i think i see examples for example you need to draw many pictures to a picture if you write this program then its very helpful in your programming.

You can try this
HBRUSH hbr;
hbr = ::CreateSolidBrush(RGB(255,255,255)); //this will draw white BackGround before drawing ICON onto it.
DrawIconEx(hDC,0,0,hIcon,0,0,0,hbr,DI_DEFAULTSIZE);

Hi Gurus
Couple of questions.
1) While using ReportEvent function to log an event, do we have to provide user id explicitly if we have to retrieve the user name when reading data from the event log? If so any sample code on how to get the current user id to use in ReportEvent function.
2) Any code sample to how to retrieve userid from ReadEventLog function and converto sid to username.
Thanks

Is there a function like fgets() but to read repeatedly every line from a string array like this?
char buf[] = "line1\n
line2\n
line3\n
...
";

You have to write your own function, using eg. strchr to find the \n

Since when is istringstream::getline() a C function?
