I want to create a program in which the user has an area where he can take lines which I provide him with (for example three lines) and adjust their sizes and locations to create a small diagram.
How can I do that with winforms?
What classes and properties should I use?
Thanks a lot
Assuming you want a .net solution, have a look at OpenS-CAD,a sample "2D CAD" project for starting. The thing is, it is written in C#, but it will give you the notion of a CAD program.
You can rewrite it with C++/Cli, and also some parts of it with native C++.
I understand from your question, that you want to give users ability to adjust the size and locations ( similar to anchors in Powerpoint and several other products ) and let him/her draw a figure out of that.
You need to use the graphics functions in that case, though some of your work like resizing might need usage of ovveriding DragDrop method too.
Here is an sample http://www.yevol.com/en/vcsharp/applicationdesign/Lesson14.htm , that might be of help to you.

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.
A sort of follow up/related question to this.
I'm trying to get a grip on a large code base that has hundreds and hundreds of classes and a large inheritance hierarchy. I want to be able to see the "main veins" of the inheritance hierarchy at a glance - not all the "peripheral" classes that only do some very specific / specialized thing. Visual Studio's "View Class Diagram" makes something that looks like a train and its sprawled horizontally across the screen and isn't very organized. You can't grok it easily.
I've just tried doxygen and graphviz but the results are .. somewhat similar to Visual Studio. I'm getting sweet looking call graphs but again too much detail for what I'm trying to get.
I need a quick way to generate the inheritance hierarchy, in some kind of collapsible view.
Why not just do it manually, it is a great learning experience when starting to work with a large code base. I usually just look at what class inherits from what, and what class contain what instances, references or pointers to other classes. Have a piece of paper next to you and get drawing...
Instead of going into the full Class Designer tool, just use the "Class View" or the "Object Browser" in Visual Studio - they present fully collapsible class heirarchies.
A good UML tool should do the trick.
Here is a list of generic UMl tools: http://en.wikipedia.org/wiki/List_of_UML_tools
There are lots out there, all with varying feature sets. Try playing with a few to see if you get the output you desire. If they free ones fail you, you might have to shell out for a good commercial grade UML tool
You can try CppDepend, it doesn't create a class hierarchy like Doxygen does but it can show 'the big picture' for your project, it also shows some code metrics.
I've had most success with valgrind and kcachegrind to do this. You run valgrind against your debugging binary, perform whatever actions your interested in, then import the output into kcachegrind to see everything you'd ever want to know about who called what, how often, and when. Plus, because your doing it dynamically, it catches cases that static analysis likely wont.
I've also had some success using Enterprise Architect's reverse engineering features, although this doesn't end up nearly as nicely (but you get a workable UML model which is nice!).
And finally, a tool called "Understand". This is pretty good at static OO analysis, but I think quite pricey and not that widely used.
Try Source Insight it is possible to configure the depth of the generated graph in this tool.
See also C/C++ call-graph utility for Windows platform
Check out SourceNavigator, it's open source, works on a bunch of platforms and has a Hierarchy Browser, a Class Browser, a Cross-Reference Browser and more that will allow you navigate and understand the code.
I'm using it for some time now especially when I have new code to go through and understand.
For a reasonably priced commercial product, you may want to check out SolidSX from Vizlogix (www.vizlogix.com). (If you are outside of North America, go to SolidSource -- www.solidsourceit.com.)
It generates a radial diagram that can be collapsed and expanded. It also integrates with Visual Studio (both BSC and .NET).
What's your definition of 'main vein'? You either want a graph reducer or skeletizer (you could find or write one and apply it to what Doxygen and the rest produce) or, 'main vein' has something to do with the function of the code and, I don't think an automated tool can help you with that. Unless you can point out to it 'These are the important bits that do input and output, show me only elements that are one or two steps away from the paths between these'. Hum, sounds like a cool tool to write :)
... the inheritance hierarchy, in some kind of collapsible view.
again, a sweet idea for a tool!
For my project report, i need to show the class diagram of the software i've built which counts around 20 classes! The problem, is that when i render the class diagram in jpeg file(either using StarUML or ArgoUMl or whatever..) we can't see the details correctly (very big picture because of the large number of classes). Well, how to manage this situation correctly? Since the report is gonna be printed on A4 pages ?
Thanks !
With 20 classes I would expect at least 3 subsystems, (modules, layers), possibly more
Make package diagram showing the relation between those, one class diagram for each subsystem.
Add class diagrams for special things you want to show. Print each on A4.
If you can't split the diagram easily into modules, I'd consider that a design smell.
Its fun to print large diagrams on huge pieces of paper (like 500 tables on A0 ;-) but it really isn't of much use.
Producing a class diagram containing 20 classes is totally useless- what does it actually show? When using class diagrams I've never created a diagram that has more than about 5-8 classes on it.
The question to ask yourself is "what useful information am I trying to show with this diagram?". Don't produce a class diagram for the sake of it!
Breaking it down to demonstrate a particular design pattern, subsystem or component is what I find class diagrams useful for.
an other way is to not show all members but only the main ones, this reduce the size of the classes then the size of the diagram. Of course this suppose you use a tool allowing to choose which operations/attributs/relations must be visible, but this drawing setting is classical
may be you tool also have drawing setting to hide some part of the operation to reduce the width, for instance to show or not the parameters, or their direction, their type etc
Bouml (http://bouml.free.fr) has all this drawing options, and as it was said has PNG and SVG exports
best regards and happy modeling

There are a few things you can do:
Bigger paper
Don't display method signatures
Don't display private methods
Partition your problem into more packages
Fewer classes per diagram
This is one of the problems with trying to treat UML like engineering drawings: Once you get it off a whiteboard, it's a poor language for communication. It doesn't read so well.
Generally a good way to deal with this is to create different diagrams for different modules or areas of functionality for your software. Alternately you could print the single image on multiple pages and show how to assemble them to form the full image.
I think it's the inherent problem that you're trying to show so many things in one diagram. Your question is just like "how can I put 100 words in a sentence without the reader getting tired of it?"
You can probably refactor it with FacadePattern. Basically it's just breaking down stuffs into modules. For e.g. Timesheet, PayCheck, BonusRecord can be ground into ManagementSystem. Product, Order can be grouped into OperationSystem, etc.
Use BOUML. The ArgoUML and StarUML are classics which everybody mention when it comes to question "is there any free UML software?". It's funny that being a historic software does not make the software unknown and unused. In case of Argo and Star the historic coefficient makes them known and used.
BOUML can export to SVG. This will solve your problems.I described the tool here
Thanks to SVG you will be able to quickly switch between birds eye view and detail view. I do this with Firefox. It's rapidly fast.
PS. I just noticed that you want to print the report. The SVG is then probably not what you want :\
Split your classes in several diagrams! When creating a UML model, you can have model elements such as classes displayed (no not) in several diagrams. A diagram is just a view of your UML model so that you can highlight modules in your specific diagrams.
I am new to using Windows Forms in C++ (and just in general), and I am not exactly sure of the name or if it's even possible to do.
Currently I am currently working on a school project in which we must make a program for an imaginary bookstore. I am trying right now to make a sort of list that shows what the "customer" is buying. I have to make it sort by price and ISBN and any other variable that the book has.
In essence I am trying to make something like the following:
I just need to know how to get started. I can't figure out what the name of the control is or how to even get it to sort every time the user clicks on the header.
You need to write a managed C++
Please look at
http://www.codeproject.com/KB/miscctrl/mfcandwindowsforms.aspx?fid=3422&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2509859
Try to do your control same way.
The WindowsForms control you are looking for is called a DataGrid
It's not entirely clear by your question, but if you are trying to access Windows Forms from standard c++ you are out of luck. Windows Forms lives in the Managed world while c++ is unmanaged. To use windows forms you'd have to switch to C++/CLI or C#. Which if you are doing something for a school project may not be an option.
If it is an option to switch languages like that. I'd start looking at C++/CLI documentation to get a feel for how things might work for you.
If you want to know Windows UI inner workings, I recommend you to stay away from .NET for now, and learn some basic things in C++ and WinAPI. Sometimes programming .NET (or C++ / COM) requires you to invoke unmanaged components/functions and you'll be glad you understand how the low-level things work.
If your project requires .NET, go on, but don't forget to make yourself some time to learn good-old Win32 / C++ programming.
Please give some more details about the question Dalze->
is there any requirement about using managed controls? or not using them?
What's your prof want you to learn from this exercise (and is how to use stack overflow to do your homework one of them)?
There's several ways to skin this cat.
If you are supposed to or want to used managed code:
DataGrid mentioned is a good simple database tool link text
An sql database could also hold all the information and allows sorting on the various sub elements.
If you choose not to use managed code you can build a few simple objects to carry the information you need, then add some sort functions for each of the variables of interest.
