I am a complete noob with regards to Blackberry development. I would like to know if it is possible to group items by header. Example: If the header is "Test", and then display a couple of items in a grid beneath it, and then have another header "Testing" and display some more items, so on and so forth. Would something like this be possible? (What I have in mind would look like the contacts on a android device, but the contact names would not be displayed in a list, but rather in grid form) I would appreciate any advice as I am currently working through the sample apps available on the BB dev site.
That would certainly be possible. The GroupDataModel with the ListView have that functionality baked in. You may want to use the GridListLayout if your heart is set on a grid layout.

I'm creating a bukkit plugin that's making a world in Minecraft outside the ordinary and that includes having NPCs (bots) entities that look like actually players and not villagers. I've already got the bots working programming wise but I want to have each bot have a different skin based upon it's name. Can I do this with maybe a resource pack or something? currently they take the names of Minecraft players with the same name but I'd like to override this.
TL;DR
Can I change the appearance of player entities by name with:
a Resourcepack?
a server side command?
playerConnection.sendPacket?
This is currently not possible without modifications to the client. If you want to, you can use Spoutcraft, but this requires users of the plugin to have the Spoutcraft launcher for the textures to show correctly.
There's no way to do this with the vanilla client, however, short of buying a bunch of Minecraft accounts and assigning them appropriate skins.
You should try out the DisguiseCraft plugin for a quick fix. DisguiseCraft is currently available on the Bukkit website. Do keep in mind that it also requires ProtocolLib to function properly, and you will need to have both installed on your server. You may find a link for ProtocolLib through the DisguiseCraft page. I currently use the two on my server and have had no issues with functionality.
If you would prefer a more direct approach however, since you are coding your own plugin, consider looking over the Lib's Disguises Developer API. Like DisguiseCraft, it too requires ProtocolLib, but the source for Lib's is publicly available and is intended to target developers. Just like DisguiseCraft, you may find a link for ProtocolLib through the Lib's page.
I have what seems like a simple task. I wrote a Windows application using C++. Now I need to add to it a capability to print forms -- nothing fancy, just plain text, with lines, tables, and simple graphics. Besides printing, a user needs to be able to preview on the screen all forms being printed.
Previously I was able to get away with this task by using an embedded Internet Explorer control and design all forms in HTML (which I like -- the HTML part.) But the problem comes with IE... hmm... I wish I had a nickel every time I heard that phrase :) Anyway, IE can print an HTML page but it does not provide any easy way for users of my software to customize page size, page margins, etc.
I spent a good deal of the last week trying to make IE Print Templates work with what I need ... but eventually failed. That stuff is very poorly documented and what I was able to do seems to randomly crash on me. So at this point I gave up on IE...
So my question to you -- is there a way to incorporate printing into my C++ program for the purposes like I described above?
If I remember correctly, printers have their own HDC, and you can draw on it. That'll work if have something simple. If you want to render HTML page using pure WinAPI, you're in big trouble.
I'd advise to abandon winapi and try GUI framework instead.
Qt 4(and 5, most likely) has text editor that can display rich text, layout engine for rich text, component that can display web pages. Read documentation a bit, and you will most likely find a way to render web page onto printer instead of screen. So far it looks like exactly what you would need.
Using Qt will add dependencies (20+ MB of DLLs for your project), but, IMO< it is a better idea than trying to use IE COM interfaces.
If you don't want to use Qt, you could try something like WebKIT, but I had some bad experiences with it, plus Qt might be just easier to use.

Try searching for GDI, if you want to use win32 builtins.
Or use another toolkit like wxWidgets. Or consider writing to PDF with some library. Or let LaTeX do the heavy lifting - writing text files is easy. The LaTeX-way works as long as you don't want to modify your output depending on the layout (one Use-Case that doesn't work with LaTeX is the "balance" at the top/bottom of each page.)
Consider having your program generate XML files and using XSLT to render them into HTML.
By attaching stylesheets you will make it much easier to customize the presentation.
I've to create an application which is made up in a tabular way, with rows and columns having cells, in a grid like format. There have to be appropriate cell-level controls as well.
Because of certain constraints, this has to be done in MFC.
I tried searching for something like Grid view/tabular view in MFC, but couldn't locate it. All I managed to get were user developed libraries on other sites, but which I cannot use because of license restrictions.
As a starting point, what should I be looking for? I've worked on Qt before, but not MFC, and am fining it difficult to locate appropriate tutorials regarding grid/tabular view.
Kindly give me a starting point, or a library name for me to start looking into.
Thanks.
Either you use something open source like the ultimate grid or CGridCtrl, or you use a library like BCGSuite. You say 'cannot use because of licence restrictions' but you don't say what you mean. CGridCtrl for example can be used in commercial and free applications. For a high-quality (i.e., with support for modern features like theming), you'll need a commercial library.
I need to create a window application that has an excel grid that users can enter data into, via keyboard or cut and paste. I would like to be able to expand and contract it in both axes on the fly. I'm just starting out programming windows applications, so any pointers to examples or keywords that I can refine my search with, would be extremely helpful.
Thanks,
James
Take a look at The Ultimate Grid. It has lots of features.
EDIT:
It used to be a commercial product, but it was later open sourced
If you are using MFC, take a look at here for data grid control. I've used it several times and it did the job.
I'm designing a MFC app in which I'd like to have a grid with 2 coloumns : both editable in which the user will input data and the app will get notified about it. The number of rows can be increased/decreased by the user as he wants - What would be the ideal MFC control to use for this kind of requirement ?
This is my first time designing a MFC app , so dont mind if it sounds too noobish :)
It's not a noobish question. Actually you have encountered a problem which bugs every MFC developer since 15 years: The MFC library does not have a built-in Grid Control. And a kind of Grid Control is what you are looking for, I guess. As far as I'm aware of, it is not possible to edit two columns in a CListCtrl. Only the first column, the "Label", can be edited.
For a Grid control you have to look for appropriate Third-Party tools which can be added to your projects, for instance as ActiveX controls. (I remember that the old Visual Studio 6 came with an "MS FlexGrid" which you could add with the component gallery to the project, but I've never worked with it, so I don't know if it's a good choice. But perhaps enough for your purpose.) Most third-party Grid controls require license fees but here is one (quite powerful) grid for free (at least free of fees but not of a license):

(or google by "MFC Grid Control" or something like that. I think there will be more free grids.)
