Hi,
I have an MDI application. In view, I have created a property sheet. In one of the pages of this property sheet, I have to create ~50 different kinds of modeless dialogs, owned by property page. All these dialogs are needed in memory as long as the document is open in the session. I have created them at application start up.
However, when I create two to three documents, my application gets very slow (~50 * 3 documents = ~150 dialogs in memory). The API CDialog::Create is taking time.
Could you please suggest a solution for this ?
Any help would be highly appreciated.
Regards,
Paresh.

Can each document share the dialogs, so you only have to create 50?
Why not create each dialog dynamically when it's needed, or are all 50 visible all the time. Sounds like a pretty intense app if that's the case. Could combine some of the dialogs?

Hi Steve,
Thanks for your reply.

A particlaur dialog has its own data. A data in a dialog in one document is different from another dialog from another document. Could you please let me know, How could I share the dialogs across two documents ?

Then also application gets slow.

I had the same problem when creating the parameter-dialogs for each element, when I had 20+ elements and tryed to open them the app was freezing. I got it improved by removing the CDialogs and using CFormViews, duplicating the views as I needed them. It gives more performance, more speed and more functionality (i.e. UpdateAllViews ()).
Paresh Chitte wrote: How could I share the dialogs across two documents ?
At the same time you are not going to be able of that. If you open the window for a document you should close it and reopen for another document. Or delete the contents of all elements and then fill them with the datas of the second element.
I made it adding a CMyDoc* pointer to the "parent" document as member variable in the CFormView, when I double-clicked on an element to be parametrized, then I got the document pointer in the CMyView and sent it to the CFormView of that element at the end of the opening process. Then used the OnInitialUpdate () to fill all the elements with the datas of the document.
You can check
this[^] and this[^] posts to have a look of what I made.
Hope it helps 
Greetings.

You have some choices:
1/ Buy a pair of binoculars and a folding chair, travel to that region, sit down, and watch for interesting things to happen.
2/ Buy a pay as you go mobile, a plastic bag, and a stick. Go to the region, put the phone in a plastic bag, hang that on a stick, and put a sign next to it saying "please phone me if you do something interesting".
3/ Make your question more explicit. Region? An area of the screen? Registry? Filesystem? (I assume it's computer related at least...)

By typing in "webcam" to the search box, I found the following article that could be of interest. Looks like clever stuff to me!

If you give some information about what you want to do, we can give helpful answers. If not, you get daft answers.

I already have as much as I can - I pointed you at an article by someone cleverer than me, that takes pictures with a webcam, and then processes them to extract information from them.
He is looking for faces - you could look for something different. But the ideas will be similar.
I wish you every success, as this is not an easy project.

Face detection requires the identification of certain features of the face.But what i have to do is ,just detect objects.It is not to be mentioned which object it is.Just have to indicate the presence of an object and track it. Any help in this area?

We use a toolkit from LeadTools I believe it is the Raster Pro. They have an image list control that can include several images as thumbnails and then if you wish to click and display at a larger size you can. Most of the image types are run-time free but if you want others like PDF and such that SDK is extra and run-times.

You can use like this code for other formats
CImage m;
m.Load(_T("c:\\1.jpg"));
HBITMAP h=m.Detach();
and then set this handle .

I have been trying to delete files that is kept opened by another process. For this, I took the handle of the file, Duplicate it and the call the CloseHandle with that handle. It works fine for almost all files. But in some cases, even though I was able to close the handle, I coudn't delete it. I am able to rename it also. For eg the event log files like CstEvent.Evt, AppEvent.Evt etc in the "C:\WINDOWS\system32\config" folder (This files are used by services.exe).
If any one knows the reason, please tell me.
Thanks
