CToolBarCtrl or CToolBar See this URL http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/_core_methods_of_creating_a_toolbar.asp It explains the differences and suggests when you should use what.

My first approach was to do the LineTo into a temporary CDC and then use alpha blending to copy it to the intended CDC, but when I do so I also copy the black background of my CDC. I'm stuck! Re: Alpha Blending Christian Graus16-Nov-01 17:28 Christian Graus 16-Nov-01 17:28  Look at the WDJ site, I have an article with code for download there regarding alpha blending. Your other option is GDI+, again my articles here cover that side of things. To alpha blend your line, you'd be better off doing your own code to calculate the line and doing the blend directly. Otherwise you're bound to blend on bits you didn't draw to, and you know the value to blend already ( the colour of the line ).

Rickard Andersson2016-Nov-01 6:18 Rickard Andersson20 16-Nov-01 6:18  I have to edit controls on a dialog. They are going to handle hours (the first edit control) and minutes (next edit control). My question is that I want to catch EVERYTHING that is done in that edit box! eg: If I write 24 and max value is 24 a message box will appear and tell the user that 23 is maximum value for that edit box, and I want it to appear while the user is trying to type isn some text in the edit box. Exactly with other too! HEELP!! ------------------------------ CodeCracker - That's me! ------------------------------ Re: EN_CHANGE? Joaquín M López Muñoz16-Nov-01 7:18 Joaquín M López Muñoz 16-Nov-01 7:18  Well, EN_CHANGE is definitely the way to go. Several months ago I posted a message about a request similar to yours: check it out. It contains some code for an CEdit-derived control that performs in-place checking of the user input. Easy task to adapt it to your needs. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: EN_CHANGE? Rassman19-Nov-01 5:05 Rassman 19-Nov-01 5:05  OnChange for the control allows you to check per key. It means though that you have to grab the text of the box, check it, then indicate the error to the user. For a box that with a maximum of two characters its fast enough, though it can be equally argued that for a box with two characters checking OnExit or when the return key is pressed is just the same. If your text could be long the OnChange check may be most desirable since the user may need to know before going too far ahead. In this case the first possible method is wastefull, that is, collecting all text and checking it all every time H He Hel Hell Hello Hello W etc For a 256 character line, there is a lot of waste. So, it is better to remember where you have already checked and where the cursor currently is. If you look at CEdit you will find possitional data available to you which you can use for this within the ::OnChange() We do it for the joy of seeing the users struggle.

Question about ComboBox Ernest Laurentin16-Nov-01 5:15 Ernest Laurentin 16-Nov-01 5:15  I just heard there's a limitation under Windows 98 about the number of ComboBox that an application can create. I can't believe it! Did anyone of you heard about this. I searched the MS Knowledge Base but I didn't find anything yet. -- God bless the World Re: Question about ComboBox Joaquín M López Muñoz16-Nov-01 7:29 Joaquín M López Muñoz 16-Nov-01 7:29  I don't know of any special limitation about comboxes, but it is a well known fact that Win9x systems can only hold 16,364 windows at a time (this includes not only top-level but child windows as well), which is admittedly a little low. On NT/2000/XP the only limit is system memory, as far as I know. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Question about ComboBox Mike Nordell18-Nov-01 12:28 Mike Nordell 18-Nov-01 12:28  As any listbox it can only hold 32K entries (actually, I believe it's 32767). Try searching MSDN for Virtual Listbox. IIRC Paul wrote a Virtual List Control for Win3.x (or was it Win9x?) "a few years" ago. automate excel Gérald Mercet16-Nov-01 4:25 Gérald Mercet 16-Nov-01 4:25  is anybody could explai me how i could create an automation which could simply open a specific workbook, a specific worksheet, update the data(using shift+F9) and close it.

Derek Price16-Nov-01 4:02 Derek Price 16-Nov-01 4:02  Hello, When an application states it requires 32MB of memory to run, how did the developer determine this? Is there a clear cut way or are they just guessing? Any ideas? Thanks! Derek
