Thanks for that, Ill look into it. I was pursuing something similar on my own, giving up on Property Sheets / pages altogether. It was just overlaying modless dialog boxes inside the main one.

The fundamental problem is that in a given area I just want to show just the panel I made. In one mode I get "tabs" like a tab control. In another mode (Wizard Mode), I get a bunch of buttons at the bottom.
So why not make both (i.e., one dialog that is a tabbed property sheet, and another dialog that is a wizard property sheet), and only show the one that is needed (based on some condition)?

If you just make one property page, you get one tab shown at the top. I didn't want ANY tabs to be shown. If you use wizard mode, you get the buttons. I do not want any buttons. I hope I am being clear on what I wanted to do.

Is there a reasonable way ( in VC6.0 & MFC 4.0!) to update CPropertyPage using UpdateAllViews?
I can manage to pass the document pointer to the page but cannot find an easy way to pass the UpdateAllViews message to the page(s).
Perhaps iterating thru all of the pages ( using MFC), posting each update in similar MFC fashion ? How?
Thanks for your help.

Why would you want to? That's for documents and views. Why not use QuerySiblings() instead?

Sure it does. Check line 289 of dlgprop.cpp and line 528 of afxdlgs.h.

Thanks David,
somehow my ancient MSDN could not help me find it.
And I just did not think the page itself would do it, but I guess that is why they call it "querrysiblings", duh!
So if I get to any page from the UpdateAllViews which starts the update, I should be able to figure it out. I guess I can pass the document pointer that way too, super.
It seems strange way to do page updates, bypassing the sheet and the frame, but if it works what a hey.
Thanks again for your persistence.
Vaclav
Addendum
It seems that there are some holes in my old MSDN docs and MFC and API functions for updating pages are not same.
It looks as API runs the update from the sheet and MFC from page. Either way, the PSM messages are hidden in MFC doc and the document pointer cannot be passed directly to the page using the QuerrySiblings.

If you need access to the document from some other place (e.g., property page), try:
AfxGetMainWnd()->GetActiveDocument();

Thanks David,
I like this better than "dragging" the document pointer thru the property sheet which does not need it. KISS!
I am still not sure about MFC QuerySiblings - from page "up" the sheet and than "down" the pages.

If you are wanting one page to be able to notify the other pages of a change, calling QuerySiblings() is the way to go. If some other route needs to take place (e.g., document notifying the sheet of a change), that may not be the best solution.

David,
I have been going round and round tryig to figure out why I am udating only one page. Did not quite catch anything strange stepping thru the MFC code. Than I read the "fine print"
"...to each
// LOADED page (a page won't be loaded in memory until it is shown)..".
Make sense, why update something which is not active.
I assume that it means when I change the page (tab) I better make sure that the whole view update business better starts again. It should work.
This has been educational for me.
Thanks.

Consider an 8-bit compiler say Turbo C, in which we have an integer of size, say 2-words i.e. 16-bits or 2 bytes. You need to store three integer values which are supposed to be as:
Name | Range | Size Required
=====================================
Integer 1 | 0-3 | 2bits (00-11 in binary)
Integer 2 | 0-5 | 3bits (000-101 in binary)
Integer 3 | 0-7 | 3bits (000-111 in binary)
In total, we need only 8bits to store all of these three values. Which means that a single variable of integer data type has enough memory to accommodate these values.
The challenge is to store all of these three variables into a single instance of integer data type and retrieve it whenever required.
In other words, you need to develop a program which can - at the maximum - use only two instances of integer data type, first one for the purpose of scanning values from the standard input device say keyboard and the second one to store the data entered by user in the form of three integer variables as discussed above and print them by retrieving it from the second instance in which the data was stored.

hi all, i'm in trouble by writing the header of a jpeg file. after i acquire the raw image and processing it by DCT, quantization and huffman coding, i would like to save it in the correct format. i can't found any libraries that help me to write proper header file, insert the 2 tables that i used (huffman and quantization), so i start writing every byte by myself... i start with the SOI marker, frame header and so on.... but when i try to open the jpg image with a viewer, it shows nothing... even in the properties do not shows any information, nor the image dimension etc, even if i insert those info like written in the official documentation... i try to scan the header with other program, but they show errors... so my question is "simple"... how i can write a proper jpeg header? thanks p.s i use VS 2010 and c++
|
|
|
|
|
have you looked at jpeglib? it has a function called "write_file_header" that looks like it might help you...
|
|
|
|
|
i can't see any function called "write_file_header", or something like that... where did you find such a function?
|
|
|
|
|
|
ok, i see, but it's useless, it only write SOI marker and APP, and i write them too in the correct way, or at least in the same way that other jpeg file are written...
|
|
|
|
|
have you tried reading it with Jpeglib, to see where the problem happens?
|
|
|
|
|
no, i will try... thanks for suggestion...
