Does anybody have a pattern handy for mapping design time help requests to name anchors in *real* online XHTML help? In other words, I assume I'd want to use an existing or custom attribute on properties, and somehow detect when help was requested for each property, then invoking a url to online help such as ourdomain/help/helpfile.html#PropertyName.

If you've got raw pixel data, you have a bmp, it just needs a header, assuming that it's word aligned, or that it has the right padding in it.
Where is the data coming from ?

hi Christian Graus,
we have live scanner that will be creating these images into one folder so now my responsibility is reading that .gry images and displaying in the form in c# .

You can create a bitmap object from a stream, you could try and see if the class can make sense of the data. If not, you could read my image processing articles, build a bitmap of the right size, and pass the data across one scanline at a time.

Isn't a raw image different then a bmp?
If not why would Xp have a powertoy Raw Image Support[^]

I found a living worth working for, but haven't found work worth living for.

Yes, it is, but a bitmap IS 'raw' pixel data, with a bitmap header.

Im writing a test prep MDI program that calls random #s to select a question, im having a problem though i need it to only call those numbers once. A solution to this or something that will accomplish the same goal would be appreciated.
|
|

|

Use Hashtable to keep the record of these numbers and if they are repeated ignore them.

Create a list that contains all the numbers you may want, in sequence. When you get a random number, make a number that is a valid index into that list. When a number is selected, grab it, and remove it from the list.

Hello everyone,
I have created a Treeview which displays the DB server and Databases in the server.
I would like to add an extra option to my application. I would like the list of table to be open in another TextBox once a particular database is selected from the TreeView. If I am not mistaken I should use AfterSelect for this purpose. But I am not able to get the ChildNode name!
Could someone be kind enough to let me know how I can get this done or point me to some online code or tutorial?
As always, thank you very much for your help and have a great day.

I have an object hierarchy where all of my objects in the application domain inherit from a base class. I also have a persistance layer which works using generics.
Looking at the code below, you realize that my object hierarchy is non-generic. But DBStore methods are genericised. How do I pass the type/class of current type?
e.g.
class DBStore
{
public T CreateObject<T>()
{
...
}
public void DeleteObject<T> (int id)
{
.. logic to delete from DB using metadata about T (containing table name) and primary key field matching 'id' ...
.. eg.. delete from typeof(T).Name where ID = id
}
}
abstract class DomainObject
{
private int _id;
private DBStore _dbStore;
public void Delete ()
{
_dbStore.DeleteObject<<big>WHAT SHOULD GO HERE</big>>(_id)
}
}
class Boat : DomainObject {...}
class Car : DomainObject {...}
I would like to be able to perform following:
Car car = new Car();
car.Delete();
or
Boat boat = new Boat();
boat.Delete();
Only things that come to my mind are:
1) Move "Delete" method from the base class to each of the deriving class: (code redundancy .. )
2) Ungenerecise the "DBStore" method (inconsistancy in DBStore -- all methods are generic, except for Delete object)
Thanks,
- Malhar

GetType() perhaps ?

I wished! C# compiler expects a class, and not a variable of type 'type'.
<pre>Type t = GetType();
_dbStore.DeleteObject <t> (_id);</pre>
--> The type or namespace name 't' could not be found (are you missing a using directive or an assembly reference?)

OK, that really sucks.
C# generics are kind of gay, they are not much use for anything too complex. They are designed so people can't hurt themselves using them, I suspect.

Why instead don't you genericize abstract class DomainObject<t>?
|
|
|
|

If I'm not mistaken, then you're suggesting something like:
public abstract class DomainObject<T>
This will break majority of the app where I'm simply keeping a reference to the base DomainObject as opposed to DomainObject for Car. You could help clarify my misunderstanding .. but:
Assuming I changed the class declaration as above (with generics), what should I change my dependent method signature for the classes that do NOT inherit from generics?
e.g.
01. class ListViewEx
02. {
03.
04. DomainObject _selectedObject;
05.
06. public void AddItem (DomainObject obj)
07. { ... }
08.
09. public DomainObject SelectedObject
10. { get { return _selectedObject; }
11. set { ... } }
12.}
- What should the line #4, 6 & 9 look like after genericising DomainObject?
- And one thing to note is that currently, ListViewEx.AddItem is designed to allow consumer to pass both objects of type Car AND Boat. If I genericize the ListViewEx to class ListViewEx <T> then a. I'll lose the functionality of adding items of multiple types, and b. Win form designer will no longer work.
Thanks,
- Malhar

I don't see enough here to say what your line 4 should be (unless maybe I'm supposed to study the previous code or something). Sorry, not enough time for that.
But yes, you are correct in understanding what I am suggesting. In my haste to make the previous post, I neglected to write my < and > with code.
As to what you need to do with your line 4, I think it's a larger matter than that. If you declare your generic to descend from a base class B, then keep a reference to B. I don't see why you would have a problem with using that reference to refer to your domain object then.

What I meant was currently line
#4 is: DomainObject _selectedObject
#6 is: public void AddItem (DomainObject obj)
#9 is: public DomainObject SelectedObject
If DomainObject is converted to a generic class, then I can't really compile the ListViewEx class with the above code lines. I must change the declarations as well to .. :
#4 is: DomainObject<??> _selectedObject
#6 is: public void AddItem (DomainObject<??> obj)
#9 is: public DomainObject<??> SelectedObject
So the correct question is, what would I substitue "??" with? if you're implying the following, then there may be a possiblity but that'd just create unnecessary classes and cause confusion:
abstract class BaseObj
{
}
abstract class DomainObject <T> : BaseObj
{
}
class Car : DomainObject <Car>
{
}
class Boat : DomainObject <Boat>
{
}
class ListViewEx
{
void AddItem (BaseObj obj)
{
}
}
The "BaseObj" is simply an empty class and it just changes the object model where consumers can begin using 'baseobj' instead of DomainObject -- since classes such as "ListViewEx" have been changed to accept BaseObj.
