well the fact is that the drive is embedded in the tag but since i've got a root node
i can't happend to get it
i use the selectnode then i'm stuck to find the level 2 node which happens to have the drive path in its tag.
root - drive 0 (tag = c: ) - node 1
. - drive 1 (tag = d: ) - node 2 - nod3 -nod4 <- selected node
nodes[0].nodes ...?

I'm in my first year of college, and I am trying to get ahead in computer science. I just bought a book called Robert Sedgewick's Algorithms 3rd Edition in C++. Could someone give me an idea? Would it be a good idea to study the whole book? Or certain parts of it? Or get direction or guidelines elsewhere? So far I've learned C++, C# and VB .Net... I thought that learning different data structures and algorithms would be a next good step, but am I wrong? There should probably be some good steps as good advice to advance a novice programmer like me. Could anyone help me here please? Thanks...

Knowing many data structures and algorithms is always good. But consider not learning too much theroretical things in such a small timespan. Its VERY important to try things out. Make up a project in your mind and just do it. You could also write an article here on CodeProject. This way you would even have some reviewers.

I can suggest you my method, but I don't tell you its the best 
When I intrested in a new language, first I read articles, about its features.
And than I start coding,  so somebody said its wrong way, but I don't think so, because, while I try to coding my ideas I brows a lot of other articles, and books, to can implement my idea. It's mutch an intristing way, but sit down in the chair, and read a million page of algorithms yahh  .
I always write little application for myself eg: file managger, picure weaver, textr editor, math formulas to help do my homework, and such little thiks.
And now I've millions line of code to write myself, nad I think I'm in friend with some usefoul language.
Wish you the best, do't give up, programming is the best thing
Yust one more suggestin:
Visit this site as often as you can, it's the best place I ever fint in the WWW.

I am working on a project which needs to constantly refresh a form. If the processing speed is low, the form refreshing will become slower and slower. Is there a way to cancel all those previous redraw messages and just process the latest one?
Thanx

Hi guys it is very important for me can create a floating toolbar that appear active if the main one is active, and not when the main is not.
Ok it need to handle hook windows message and it is not relly simple but it is possible you can see it exists and works in much graphic program gui and you can see a c++ example here: http://www.codeproject.com/docking/dockwnd.asp
Ok now i need a C# version of this example but i don't know where.
If someone know where can i learn or if he can show me some row of code i'm grateful.

How many times are you going to ask this question, then ignore the answers we give??
Last time. You DO NOT hook windows messages to get this to work!!!!!!!! Only ONE window can ever be active. I KNOW there are applications that are out there that give you the ILLUSION that two windows are active. This is NOT the case. You have to owner draw the tool window to get it to appear active when it really isn't.

Now i'm so curious to know why isn't this the case!!
What difference came from?
I answer you it is the same stuff!!!!! Not different!!!!!!
And in the tutorial you can see they use hooking windows message to get this ILLUSION! not using a own drawing becouse if i use a blue drawing for the tite bar of my toolbar like the main and the user use a grey windows impostation it works bad!!!!
So i tell you if you don't know how, please don't answer telling these things!
Thanks

Why don't you read the article? It's actually very very simple:
http://www.codeproject.com/docking/dockwnd.asp#DEACTIVATE[^]
And no, you don't uses hooks to intercept window messages. Simply override WndProc in your derived class, check for WM_NCACTIVATE message, and before calling base class, always set wParam to true (if your main window has focus.) In the article it takes two lines of code.
[EDIT: A couple of things: First, VS.NET and Office *do* use ownerdrawn title bars. And second, in VS.NET, a toolbar's caption bar never is painted active (only for docked windows.)]

ok, but how can i set for my window a my owndrawed title bar?
|
|
|
|

You don't. You set your window to have no titlebar at all, and then paint one at the very top.

Hello All,
I have a couple of questions. First I am using v2.0 of the Data Access Application Block. I am using the filldataset and executedataset functions of the DAAB. I have been reading some on typed vs untyped dataset. My question, if I created a typed dataset which contains certain tables and then I use the filldataset and pass in the typed dataset and a sql statement with the new table name for the sql statement. Where is the advantage. Is now the new table I created in the typed dataset easier to access. I am confused by why would I use a typed dataset and create a new table from a sql statement and put it in the typed dataset.
Thanks

Typed dataset is much faster than untyped dataset.
|
|

|
|
Is it? I wonder why it should. Do you have any links regarding this?

Hi Robert
The DataTables, DataColumns and functions are well defined in typed dataset. In design time itself you will know the number of tables, number of columns in a table and its data type. But in un-typed dataset everything will be generic.ie number of tables, number of columns in each table and its data type every thing will be decided and created by runtime. It depends upon the query or stored procedure. When we try to fill an un-typed dataset using adapter first runtime will execute the query or stored procedure. Then it will analyze the results and based on that it will create tables columns in dataset. So it takes more time than typed dataset.
Tnx

hi all.

If you don't want to use componentts/API (EG: Skype or MSN API) for this function, I tell you one way (I know it's a litlebit supid, but... )
Yuo can find a lot of articels for the sound recording, and playing, so:
- record the souind into a file
- get the bytres of this file, nad transfer it
- on the other side play back the file
But I think it's a werry slow way.
Please if you find a way to solve this problem, post it back tom me, I'm interested in this ide too.
Thanks

Hello,
I have a database table with 2 fields, DepartmentCode, and DepartmentName. I want to add the values of these 2 fields into a combo box from the database. I can add one field, but how can you add 2 fields to the combox so that when the user clicks it, it will display all the departmentCode and Department name in 2 columns.
I can do this with just one field, but l am having trouble tying to display the extra field. Is this possible in a combox box?
Thanks in advance,
Steve

People are talking about this all the time.:::::
How do you design a data model for object oriented applications? Should the data model be designed first, or should it be derived from the object model?
*************************************************
I really do not aggree with this.OO is not the coolest thing to model the world.
The value and the pointer of the value should be seperated such as in adaptive object models where we can model the world with 4 classes.
entity entityType attribute and Attribuetype....(+ accountability by martin fowler if u like)
the reason the OO models fail as they are trying to model the world which is changing all the time.

And what do you want to tell us with that?

Please reply to the forum in future:
erdem sahin [xxxxxxxx@hotmail.com] to me
adaptive object modelling is ALL about design patterns.
u have to use 16 of the design patterns.it can be kind of complicated in the
beginning but what u end up with is a code that is adaptive where u dont
have to change your code with the new requirement.
Something has to change when the requirements change. If it isn't code then what is it?

the structure of traditional OO systems became immutable after deployement.
the abstraction levels in AOM systems have us leverage our infrastructure by not using TUPLE logic in the first place.
ForExample:
TUPLE LOGIC::: ID:126 Name:John LastName:smith WifeName:Mary
tuple logic is just so artifical,and do not represent the world.Think about a persons brain cells and the his memory do u think every thing is stored with only one pointer?
****************************************************************
AOM LOGIC::::
IDNAME:126 Name:John
IDLASTNAME:1256 LastName:smith
IDWIFENAME:34545 WifeName:Mary
every value has its own id.
AOM systems make a TUPLE only at runtime.
