That's an MSPRESS book basically.

It was published in MSDN library until 1998, but MS decided to remove it to encourage people to use only VBA for Excel, and now Excel Xml,

I've just found the library and header files. It was included in some example zipfile Smile | :)

There're no docs but everything that's in the example is very clear.

Hi,
I got some troubles with VC6 and STL, I found on google's usenet archive that a SP is recommended. Which one should I apply, latest SP5? Any problems or new bugs that I should know?

Thanks

okay, it's done.

Still the same problems and I need to run a workaround still. Is it known that STL implementation is a little clumpsy? Had no problems on Unix platform.

Regarding STL compliancy with ISO, indeed you are very unlikely to be able to compile without a slight change, such like project settings or one or more #ifdef#define. Post a code snippet if you are stuck, I am sure one of the people out there will help you in no time,

okay - thanks a lot for offering help! Smile | :)

I got the hint already to use 'stlport' or other supplementary STL libraries. I'll post problems, when it can't be solved with a little googeling.... have a nice weekend

Hiding a dialog on view switch

What problem are you running into? There may be a fix you can apply or the other option is to use another implementation of STL such as http://www.stlport.org[^]

I've run into problems before (can't remember exactly what) and had to work around them.

I have an MDI application where the view class has a dialog box as a member. When I change between the views I want to hide the dialog box. In the CView::OnActivateView function i hide the dialog when I change between the two views.

My problem is when i change from the dialog box to the the other view. I don't know how to hide the dialog box i that case. Can somebody please help?

I also committed the crime of posting a programming question in the Lounge.

thumbnail using imgthumb ActiveX control

Hi.
I want to display thumbnails of images. I tried using the "Imaging for Windows" ActiveX control imgthumb.ocx (Kodak image thumbnail) that comes along with Windows2000. I use VC++6.0.
I want to dynamically create the thumbnails. I am unable to figure out which functions to call.
Here is my code snippet.
It does not show any error, but nothing is displayed.
Can you point out what is wrong?

m_thumb = new CImgThumbnail;
BOOL res = m_thumb->Create("Thumbnail", WS_CHILD | WS_VISIBLE | WS_BORDER,
CRect(100, 100, 170, 170), this, 1341);
m_thumb->SetThumbWidth(50);
m_thumb->SetThumbHeight(50);
m_thumb->SetImage("c:\\flowers.jpg");
m_thumb->SetEnabled(true);
m_thumb->SetThumbCaption("seen???");
m_thumb->SetThumbBackColor(0);
m_thumb->SetThumbCaptionColor(100);
VARIANT image, page;
BSTR bst;
CString str="c:\\database_n\\flowers\\21099_wallpaper110.jpg";
bst = (unsigned short *)str.GetAt(0);
image.vt = VT_BSTR;
image.bstrVal = bst;
page.vt = VT_I2;
page.iVal = 1;
m_thumb->UISetThumbSize(image, page);
VARIANT thumbno, options;
thumbno.vt = VT_I4;
thumbno.lVal = 1;
options.vt = VT_I2;
options.iVal = 0;
CString str1 = m_thumb->GetImage();
m_thumb->DisplayThumbs(thumbno, options);
//m_thumb->Refresh();

However, the thumbnail is displayed when I put the control in a dialog box (using the editor), and set its properties.
Where am I going wrong in the dynamic creation process?
Hope somebody can throw some light.
Thanks.

I did that in CDlg::OnInitDialog() implementation :

CRect rect(10,10,150,150);

m_pCtrl = new CThumbnailctrl1();
BOOL bOk = m_pCtrl->Create(NULL,
                           "thumb",
                           WS_CHILD|WS_VISIBLE,
                           rect,
                           this,
                           100);
m_pCtrl->SetImage("c:\\011.jpeg");

// where dclaration is : CThumbnailctrl1 *m_pCtrl;
//   CThumbnailctrl1 is a class wrapper for the OCX (generated by msdev)

And when I ran tha dialog-based MFC app, I saw the actual image on screen. At least this works so far.

That is working for me too.
But my aim is to place the control in a CHtmlView-derived window. It is not getting displayed there.
Can you figure this out?
Thanks for the response. Roll eyes | :rolleyes:

Easy to figure out, CHtmlView is a placeholder (understand : just a window border) for the web browser OCX. Hence you have no chance of displaying your control on top of it, if that's that what you'd like to do.
Well to be honest, you may achieve some "BringToFront()" or something if you hack down COleControl internal behaviours, but as you can imagine, it is highly not recommended.
I don't know exactly what you want to do wrt to CHtmlView. I would understand with a CDialog but I don't get it with CHtmlView. By default, I would suggest to create a default CView (would behave exactly like a window, but in a SDI/MDI model), and to create one or more of thumbnail controls in it,

Thanks for your reply.
My aim is to display the thumbnails of all images contained in a selected folder. For this, I have created an Explorer-style app, with a CTreeView-derived window as the left pane and I just put a CHtmlView-derived window as the right pane (anticipating future use). Using the left pane, the user can navigate to the various folders in the system. When the user clicks a particular folder, it will expand in the tree view. Also, I want the thumbnails of images avl. in that folder to be shown in the right pane.
(If you have used the IrfanView software, you will come to know that I am trying to implement the Thumbnail option avl in it).

But after you have pointed out, I have realized that it's not possible to display thumbnail control in the CHtmlView-derived window.
So, I have a plain CSrollView-derived window now as the right pane. But my problem is, I don't want to create/destroy the thumbnails every time a new folder is selected. I want the thumbnails to be remembered once they are created; something like the CTreeView behavior itself. Confused | :confused:

Can ou suggest some way out?

Thanks a lot.
