Is there any way to get SpinBox Up state?
Thanks in Advanced

I was talking the ButtonUp Event for SpinBox.

Assuming you want to know when the Up part of the spin box control has been clicked, the control sends a WM_NOTIFY message with the UDN_DELTAPOS code to its parent window.

I have an Dialog based project and if I try to add a windows messgaehandler for WM_GETMINMAXINFO, I have to change the filter from dialog to window in order to have that message available in the list. Is this ok? What is the reason for this?
Thanks,
ns

Hi ns,
You're doing fine. This filter is just an Visual Studio UI thing designed to minimize the number of handlers the programmer is exposed to, so that only the most commonly used are displayed. Sometimes it happens (as in your case) that you go nuts looking for that handler and it appears nowhere. IMHO the filter thing does more harm than good, and it's badly implemented (it appears in a different tab than where its effect is apparent.)

Good to hear from you again!! Appreciate the quick response.

Hi,
the reason is that the WM_GETMINMAXINFO is usually only avaiable for Windows. The Visual C++ help index says that this handler fills an array with information of the window. However, since dialogs are considered as a window this seems to be corrected.
Kindly yours.

Hi,
My app minimises to the tray using a kind CP person class. It all works really good but my icon is 256 colors and in the tray it looks like it is 16 colours and does not look very good. Can I show it in 256 colors in the system tray or not?
Thank you.

Be sure you don't have a 16 color icon as well.

I definitely have not. I have two 256 color icons. I have just now put a 16 color icon in to see if it will use the 16 color one I made which does not look as bad as the one it displays in the tray. I think that perhaps the tray icons are not even 4 bit (16)color.
I can not find anything in MSDN about this problem.

To avoid icon distortion, be aware that notification area icons have different levels of support under different versions of Microsoft Windows. Windows 95, Windows 98, and Microsoft Windows NT 4.0 support icons of up to 4 bits per pixel (BPP). Windows Millennium Edition (Windows Me) and Windows 2000 support icons of a color depth up to the current display mode. Windows XP supports icons of up to 32 BPP.

Thank you.
I have read it and what it says about Windows 2000 is strange because I am running Windows 2000 and I get icon distortion. My icons are definite 256 colors and my display mode is definite 32 bit mode.
I wonder what is happening?

I have a CEdit control mapped to a large size text field. When the Read Only box was unchecked, all lines were showing up fine when I scrolled up and down the control. But I have to set the box to Read Only. Once Read Only was checked, when I scrolled up and down using the scrollbar, all text in the edit box was over written by other text. I looked into help but unfortunately was not able to find any information on this problem.

Sound like an error in Comctl32.dll. Try to get the latest version from MS. (I don't have a link - it can be done with MS's download utility)

Hi,
the same phenomenon occurs from time to time in Word. Don't know what causes this problem. Are you using the TRANSPARENT property anywhere in your code???
Regards.

Yes, I have to use TRANSPARENT property to set static labels background while setting background color to the form.

The only download I saw was for Window95, too old. Can you send me the link?

Use the download utility - the one with the the little hard drives on it.

Can not find it. A url would be greatly appreciated.

I don't have a URL - Even if I had a URL, MS shuffles thing around so much, by the time I gave it to you it would be out of date.

Hi,
you told me that you are using the TRANSPARENT mode for displaying your data. The TRANSPARENT mode usually hides a given rectangle around a text in a window. This rectangle would usually require a certain space to be displayed - visible or not - on the screen. So if you don't leave enough space for your characters - that is the height of a character in a certain font and the space for the rectangle - you may overlap the rectangle of one line with another. Note: the rectangle i am speaking of is an abstract rectangle which cannot be physically displayed.
You can calculate the necessary number of space for a specific character by using the following code:
TEXTMETRIC tm;<br />
int cxChar, cyChar;
cxChar = tm.tmAveCharWidth
cyChar = tm.tmHeight + tm.tmExtarnalLeading
The TEXTMETRIC structure encapsualtes almost all avaiable information of chars. What your code suffers is a lack of external leading that is the space around a character that is needed to display is. For more information on this structure I refer you to the MFC documentation or
Charles Petzold's Programming Windows 5th edition.
This may look a bit comlicated but in the end its somewhat straightforward
Hope it works
Regards.

Hello.
Part of the interface that I'm developing requires that there be some sort of interactive periodic table of the elements. I'm not completely sure how I should go about doing this and I was wondering if anyone here had any good ideas for me, or knew where I could find some info on it. I need it to look like the traditional periodic table, but the user is able to click on any number of the elements, and the element number for the ones they select will end up in a list. The only thing I could think of doing was creating one button for each of the elements (which is a lot of buttons!!) and each time a button is clicked, the element number is either added or removed from the list. Anyone have any better ideas they'd like to share with me?
Thanks a lot.

You could make it so that by dbl-clicking anywhere within that element's cell causes the element to be added to the list. If part of your element class contains info about it's screen coordinates and you create a BOOL ClickInBounds(POINT) member, then you could handle the WM_LBUTTONDBLCLICK by calling each elements ClickInBounds() with the double-click coordinates and it return TRUE if the dbl click was within it's cell.
