I have used Castle Windsor[^] to accomplish something similar. There are several other .NET inversion of control containers that may also work (StructureMap, Spring.Net, Ninject, etc.) but I don't have any experience with them.

Given your rate, 1/2 every 6 months, I doubt a generic system is going to provide an advantage.

What about a scripting engine for the business system/ part of the business system. If you require functionality to be dynamic. It could be scripted and changed on the fly.

This is what I have used with one of my programs.
1: Have a page on the Internet with the latest version number.
2: When your application loads, read the Internet file version and if it is grater than your application then....
3. You can give the user the option to upgrade now or upgrade now without prompting the user.
4: Download and run a temp upgrade.exe program. Then quit your main application.
5: The upgrade.exe will download the new version (Using the same file names and locations as the old version)
6: Run the (new) main application.
7: End the upgrade.exe program.

no. I am trying to write a replacment windows shell and I have got to the stage where I need to replicate the system tray. The point where notify icons are placed. Sorry my orrigional post obviously wasnt verry clear on that.
Tanks anyway

Yeah, so write an implementation of NotifyIcon for your shell as I think the previous poster intended  Basically, the interface for NotifyIcon tells you exactly which functionality is needed and how it is implemented. Basically you can use the same interface and supply a new implementation for it specific to your shell.
Edit:
On the implementation, basically what you need is a toolbar which can display icons, has customized menu's for each icon, has tooltips, and perhaps one or two more features. Here too, the NotifyIcon class gives great amounts of information how to implement each feature.

I am trying to implement a simply task that appears to be amazingly hard to accomplish in .Net: Sorting a column in a datasource bound control (e.g. DataGridView), not based on the underlying values (i.e. simple string comparison on the values) but on some custom rule that I want to define.
I have a DataGridView that is bound to a Bindingsource which in turn is (via Dataview, .Net internal stuff...) bound to a Datatable. This is plain vanilla stuff, out of the box. If I was happy with the default sort behavior, i.e. sorting columns by the values in DataTable, everything would be easy, even automatic.
However, some of the contents in the Datatable is not in a user-friendly format, so it must be formatted for display in the datagridview (e.g. by overriding the CellFormatting event). If I now sort the control by that column, the rows will be sorted by the underlying values, and not by the displayed text, which is bad.
I cannot use the Sort() function nor the IComparer overwrite of the DataGridView since I am working in databound mode. How in the world then can I intercept the sorting mechanism and tell the DataGridView how to sort this column properly?
It strikes me as odd that the standard data source - binding source - control model in .Net appears to have no provision at all for custom sorting! What is even odder is that a primary reason for the whole concept of a BindingSource is just sorting and filtering!
There must be an easier way than writing 1000s of lines of code to create my own DataView or IBindingList derived class that will allow this kind of customization, as recommended in various articles. This seems such a common scenario that I can't believe there is a more elegant way...

AFAIK you must apply your (custom) sort on the underlying data structure, not the DGV itself. So set the DGV to programmatic sorting, handle the cell click event (checking for row<0 and getting the column index), and sort your DataTable or whatever is underneath the DGV.

I'm not sure I understand the difference between these two events (Form.Deactivate and Form.Leave). Could someone enlighten me please?
|

Occurs when the form loses focus and is no longer the active form. (When the title-bar of the form changes from blue to gray)
Occurs when the input focus leaves the control. (When the cursor focusses another control/window)

Alright thanks, but isn't that pretty much the same thing? I'm talking specifically about a form, not just any control. So "when the cursor focusses another form", isn't that precisely when the form's title-bar changes from blue to grey?
|
|
|
|
|
Yup. The active form is usually the one with input-focus (fails sometime when apps modify the z-order). Hence, if the input-focus moves to a different form, the new form will should be activated. Even if the validation would fail and the focus retained - the active form would be the one with focus.

OK, thanks. So, am I correct that, as regards Forms, there is no difference between Form.Deactivate and Form.Leave?
|
|
|
|
|
Well, there is, otherwise one of both would be redundant. Imagine you open a form, has focus. Now I click once on a tray-icon. Just tried it, and the form raises the Deactivate event, not the Leave event; the form still has the input-focus (for your app, and will continue there when it's activated again).

No, it's not. It's entirely possible to have a form deactived, but the focus never really leaves the confines of the form. I know, it's rare, but it happens...
It's also possible to have the focus leave the form, but never deactivate the form by clicking on someone outside of it.
What you do with those events is up to you.

No It Was Help-Full But It Was Related Using By DataSourse, & I Need Answer Related With Using Business Logic (a multiple classes). & Database Was DB2.

hi ,
You can use <item template> along with <table> and <gridview>
kindly search on google "item template with gridviews".
You will get you solution there.
You have to do this coding on .aspx->Source file.
