FYI, while this may translate directly to something meaningful in your language, in English it sounds retarded, and we're used to hearing it from people who write clueless posts where they expect us to do their work for them, and show no signs of having tried anything themselves. You appear to have tried *something*, but you post no code, so it's really impossible to help you, and easy to judge you based on that phrase ( which I admit is not fair, but again, you're not helping yourself, either ).

Sir, if there was a feature to 'follow' your posts to see your replies instead of luckily stumbling on them, I would use said feature.
Better then my morning coffee again, you're 2 for 2.

The problem is with the type of database you are using. Oh hang on you haven't specified it.
I think it migh be the fist step you tried. Oh hang on, haven't said what you have tried.
Oh hang on this isn't the DB forum.

Your question is not clear.
May be i can help if you answer the following.
"Do you want some code through which you can take backup programatically.
Similary restore an existing backed-up DB."
And are you using 'SQL Server' db ?

If you want a complete program, you can buy one. If you want complete source code, you should ask on the job board for someone to write it for you. Be careful, the web is full of people who claim to be programmers and are not, they just take your bid then ask people in online forums like this to do the work for them.

Hi All.
I have a StaffMember class in my app that is inherited by my data access layer to StaffMemberOracleUDT. My reasoning for this is that the OracleUDT version has the data access part needed to convert an Oracle object to something I can use and then I can just send back the StaffMember base to be used in the UI layer.
The problem I'm having is that I need to access the properties in the base class (Name, ID etc) but I also need to over ride these in the inherited class as each property needs a special OracleObjectMappingAttribute added to it that cannot be added to the base as I would then need to reference the Data Access Layer in my UI layer which shouldn't really be done.
Any help is greatly appreciated.

The short answer is "yes".
I think it's a slightly odd dependency pattern you're creating - your DALs will depend on the business layer - but it is possible. And you don't need to reference the DAL from the UI - just the business layer.
In your business layer you'll have:
public class StaffMember
{
virtual public string Name { get; set; }
}
and in the Oracle DAL
public class StaffMemberOracle : StaffMember
{
[SomeAttribute]
override public string Name { get; set; }
}
You never actually "convert" between these two types: The derived class IS the base class plus something of it's own.
public StaffMember LoadStaffMember(int id)
{
switch (DB)
{
case "Oracle": return OracleDAL.LoadStaffMember(id);
case "MSSQL": return MssqlDAL.LoadStaffMember(id);
...
}
}
Not that I'd do that! Rather than have a bunch of switches in every method in the business layer that uses the DAL, create an interface that all DALs implement. Then your code will be something like
public StaffMember LoadStaffMember(int id)
{
return CreateDAL().LoadStaffMember(id);
}
public Something LoadSomething(int id)
{
return CreateDAL().LoadSomething(id);
}
IDAL CreateDAL()
{
get
{
switch (DB)
{
case "O": return new OracleDAL();
case "MS": return new MsSqlDAL();
...
}
}
}

Thanks for you reply but I am having a few problems. I have set it out like you have above but my properties have private members associated to them. If I have code in the get & set on the base I get an error in the inherited class "inherited.staffid.set cannot override inherited member base.StaffID.set because it is not marked virtual, abstract or overrride." My base class property is marked virtual and the inherited is marked override.
public class StaffMember
{
protected int staffID;
virtual public int StaffID
{
get { return staffID; }
set { staffID = value }
}
}
public class StaffMemberOracle : StaffMember, INullable, IOracleCustomType
{
[OracleObjectMappingAttribute("STAFFID")]
override void int StaffID
{
get { return staffID; }
set { staffID = value }
}
}
I think I may be going about this the wrong way.
Cheers

override void int StaffID should be override public int StaffID .
|
|
|
|
|
Sorry that was a typo!
I think I have solved it. I need to use the new keyword new public int StaffID to declare a new version of the property. Intellisense seems to like it
Thanks for your effort

No, you don't need "new". You need "override". The "new" keyword is for member *hiding*, not overriding.
To understand why, you need to know about the difference between virtual and non-virtual members, also often described as "late-bound" and "early-bound" members. It's also helpful to understand the concepts of reference types and value types.
A couple resources I dug up for you quickly (you may want to google for others if they don't work for you):
Value Types vs Reference Types[^]
Virtual Members vs Non-Virtual[^]
Or google "polymorphism" and these other terms I've mentioned.
In brief, virtual members work as follows: When a member is accessed, such as method Foo(), the implementation of that method is resolved ("bound") at run-time, based on the run-time (actual) type of the object. For non-virtual members, the implementation is resolved at compile time (when you compile), based on the declared type of the reference.
For example:
public class A
{
virtual public string Foo() { return "A.Foo()"; }
}
public class B : A
{
override public string Foo() { return "B.Foo()"; }
}
void test()
{
A obj = new A();
MessageBox.Show(obj.Foo()); // "A.Foo()"
obj = new B();
// Now, "obj" is still of declared type "A", but run-time type "B".
MessageBox.Show(obj.Foo()); // "B.Foo()"
}
If instead you declared A.Foo without the virtual keyword and used new to hide this method in B, the second call to "obj.Foo" would still resolve to A.Foo, because obj is of declared type A.

Thanks for your reply but it wouldn't work for me earlier. Probably to much going on.
Just tried and it is working. Thanks again for you help.

How much more clear could the message be?!?
Hold on, with my psychic powers I can determine that your application has some functionality that relates to Microsoft Excel. Am I right?

But from where do i downmoad it from, i tried updating office with sp3. has not solved the problem yet.

I tried looked for dll files for office before and could not find. you need full version and maybe you can copy them from there.
I believe the version you want (8.0.0.0) is excel '98 so you need to get a copy of that and use those files. If you did not want to use such an early version then you need to specify the version in your code. But you will still need the appropriate files on your target machines.

Checked Items is a collection, as you can see. You need to use foreach to step over this collection, and get the names of all the checked items.

You mean you want to see Check
foreach (string checkedval in this.checkedListBox1.CheckedItems)
{
}
