One way to do this would be to generate a unique, time-limited url for download by a specific customer. The link would expire after the software has been downloaded and/or "n" units of time after that event or after the customer has made the purchase.

I'm decent at programming applications, but pretty ignorant when it comes to web programming. How do you do what you said?
|
|
|
|
|
Create a database table, such as:
CustomerDownloads
id unidentifier
ordertime datetime default(GetDate())
downloaded bit default(0)
When creating the link for them to download your software, generate a new guid to include in the link. Enter this guid as the id in the table. When the user wants to download the software, use the guid to lookup the order, check the time or downloaded flag as necessary.
Simplistic, but thats the gist of it.

Are you asking how inheritance work in runtime?
If it creates an instance of both the baseclass and the subclass?
In that case, no, it doesnt create an object per class.. it creates only one single object.
You can think of it as if all the code in the base class is copied into the subclass when you compile.
(this is not quite how it works, but it might be easier to grasp the concept if you think of it like that..)
"this" and "base" are the same object, its just that when writing "base" you can reffer to methods that was defined in the baseclass... but its still the same object, just a different method you are using.

hi ,
I'm in a little trouble these days ... as im wokirng on a new project and needed help.
Lets first go thru wat's troubling me :
A hierarchy will be set up for the ordering process of Hierarchy users. The order process will work from level 3 to level 2 to level 1. Please note that any level has the ability to order/quote products but can only be submitted to checkout from level 1.
The process can begin from level 3 when they log into the system and at this point they will then be able to search the catalog by clicking through the category, subcategory, and product pages to purchase/quote a product. Once they determine the product to purchase by going to the product detail page that item will then be sent to the shopping cart.
The user can either have the choice to proceed to checkout or continue shopping. Once they are complete and their shopping cart is up to date, they will then submit the order for processing. The email will at this point be sent to the Level 2 that is assigned to be above the level 3 user for them to approve. The level 2 users will have the ability to add, edit, or change the order by adding or deleting products as well as change the quantity of the product. Once they are satisfied with how the order looks they will be able to approve or disapprove the order. If the order is disapproved, they order will be deleted from the site completely and email will be sent to the users of level 3 that submitted the order letting them know it was disapproved.
If the order is approved an email will be sent to the user of level 1 that is assigned to the level 2 user through same department. Once the order has been approved by each level then they will not have the ability to make changes to that order. Level 1 will be responsible for all departments . When the level 1 user receives the email they will be able to log into the system and view the order status window. The level 2 users will have the ability to add, edit, or change the order by adding or deleting products as well as change the quantity of the product. Once they are satisfied with how the order looks they will be able to approve or disapprove the order. If the order is disapproved, they order will be deleted from the site completely and email will be sent to the users of each level that previously viewed or submitted the order letting them know it was disapproved
This is the scenario .how to make such a hierarchy ,,any ideas ,,any starter kits recommeded that resmbel to this scenario ,,or ur thought will be a realy BIG contribution.
im using ASPDOTENT 2.0 and sqlserver 2005 , c# as the language.

How can I make a simple descending timer???
Thanks in advance

Funnily enough, the Timer[^] Class. 
The timer counts-down to a given interval that you set (in milliseconds) and when 0 is reached an event is fired.

Hi ZaidIT
can you tell me y you r wish count down timer?
becuase o9f we can use increment timer many ways.
thanks

Why does it matter? It is surely a requirement. There are many reasons to have a decending timer. Most of them have to do with UI stuff. Such as informing the user that a certain event will fire in, well, lets say 30 seconds, for example.

you question is strange,
As far as i understand that you want to add control at runtime,
You can add controls at runtime like this.
Label L = new Label();
L.Name = "L";
L.Location = new Point(0,0);
L.Text = "ABC";
L.Size = new Size(75, 23);
this.Controls.Add(L);
hope this will help

Thanks for your response,
My problem is
From the XML file I will read the controls Names and I will create them at the runtime.
This is what I need
Thanks for your respnse

how secure is the key container?
are there a better solution?
any artickle on the matter will be great help
|
|
|
|
|
The standard 'key container' is a folder under your user profile, under Application Data\Microsoft\Crypto\RSA. Each file represents an issued key. The file itself is encrypted with your master key, which is itself protected by a key derived from your logon password.
The folder is protected by an Access Control List which permits only Administrators, yourself, and the system (represented by the LocalSystem or SYSTEM security principal) to read and write to the folder.
So the ultimate security of the key container is based on the strength of your logon password.
