Under which account is the web site running, and does this account has write rights to the mdb file, and create rights on the directory?

I am using MS access 4.0 datbase and ADO to connect to it
but there is a problem mentioned above.

You have to change the file permission for the file, not for the virtual directory. The write permission on the virtual directory decides what IIS allows external users to do, not what the file system allows IIS to do, so that setting should definitely not be enabled.
The FAT file system doesn't support permissions at all, that's why permissions is not a problem on a FAT drive.

It appears that I will need some of the features of IIS 6.0, but currently have IIS 5.0 installed. How do I go about the upgrade? Do I need to buy an upgrade or can I download it?

IIS 6 for Windows server 2003!

You can't upgrade IIS 5 to IIS 6. They come with different versions of Windows, so to get a different version of IIS you have to get a different version of Windows.

Hi,
I want to share this problem. I have a datagrid that will help me Insert data into sql database. So I made a button On my form so that when I press the button a new row on datagrid should be created and I could be able to insert data. But with this code below I've failed could someone help me and tell me where I'm going wrong:
private void Page_Load(object sender, System.EventArgs e)
{
if (! IsPostBack)
{
Fill();
Bind();
}
}
DataTable table = new DataTable();
private void Fill()
{
SqlDataAdapter adapter = new SqlDataAdapter("select * from dbo.DashBoard", con);
adapter.Fill(table);
}
private void Bind()
{
dgis.DataSource = table;
dgis.DataBind();
}
private void InsertEmpty()
{
table.Rows.InsertAt(table.NewRow(), 0);
}
private void bttnew_Click(object sender, System.EventArgs e)
{
// inserting
dgis.EditItemIndex = 0;
// modify text
EditCommandColumn ecc = (EditCommandColumn) dgis.Columns[6];
ecc.UpdateText = "Update";
// fill table, insert empty row, bind to datagrid
Fill();
InsertEmpty();
Bind();
}
private void dgis_ItemCommand(object source,System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
// stop editing
dgis.EditItemIndex = -1;
switch (e.CommandName)
{
case "Insert":
break;
case "Update":
break;
case "Cancel":
break;
case "Edit":
// begin editing
EditCommandColumn ecc = (EditCommandColumn) dgis.Columns[6];
ecc.UpdateText = "Insert";
dgis.EditItemIndex = e.Item.ItemIndex;
break;
}
// fill and bind
Fill();
//InsertEmpty();
Bind();
}
Thanks.

Hi,
I don't know where to start with the following, I would like to create a webpage with a list of physical products. Once a user selects, a new dialog pops up with the product view in 3D. By dragging within the window, the user can rotate the view of the product (and zoom as well using another control). Anyone have an idea how this could be done?
THANKS!

You'll need to get into DHTML for most of it (javascript and DOM with some CSS thrown in) and probably Ajax to load product details. The rotate view I guess would need Flash.

Hi
Most of us as web developers know how to hash user passwords within our database in order to prevent hackers from abusing stolen passwords in case they are stored in a plain text format. But I personally haven't seen any thing as a best practice (something standard recommended to all developers) to protect our sensitive data from being stolen.
As an example of a situation where we might want to encrypt some of our database fields, consider a shopping site which sells all its products through custom credit cards designed and delivered by your company whose information (including amount of each card's credit) have been stored on a database. Now, as the owner of such database, I'm mostly obsessed with these concerns when it comes to data encryption in database:
1- Which of the symmetric encryption algorithms is faster or recommended for encrypting "credit" field?
2- Where do you store your encryption key? in source code? What if your source is stolen too? Is it sensible to rely on this fact that nobody can access our compiled .net assemblies on the server and hence storing the key there?
3- How do you detect a new record that hasn't been inserted to database by your application but by a hacker?
* These are my main approaches concerning above issues:
1- In order to prevent passwords from being seen: I'll hash them with a salt
2- I order to prevent a hacker from modifying the amount of a card: I will hash and store the credit amount using a salt (e.g. Hash("34$"+salt)), and I'll also store the encrypted value of the credit amount (e.g. Encrypt("34$"+password)). Now, whenever I see that the hashed credit value of a record doesn't match the previously hashed value, I'll restore the credit amount from where I've already encrypted it.
3- In order to prevent a hacker from inserting his own credit card into database: I'll assign a unique ID field to each card, which has been generated based on a rule (like a serial number). So, the hacker won't know how to generate new valid card IDs unless he accesses my code and knows the rule.
The last concern: Checking all the constraints mentioned above, doesn't it hit the performance considerably? If so, what should we do then?!!! 
Any helping ideas are most welcome and greatly appreciated!

Performance won't be an issue. You are going to want atleast a 1024bit algorithm for credit card details (although you really shouldn't store these). Do a bit of research on Asymmetric encryption.

Hi
I know what asymmetric encryption is and know that it's much slower than symmetric. What kind of info should I search on asymmetric encryption? And why do you think that performance won't be an issue?!
thanks in advance

As said before, performance is not an issue. You should asymmetrically encrypt or hash all sensitive data.

^[A-Za-z][A-Za-z0-9_]{5}$
Note that best-practice dictates that your password should be at least 8 characters. Also insisting that the password starts with an alpha character weakens the password.

[0-9]

Cannot do using regular expression.
Hope that helps.

hi all
i setup Ajax 1.0 after that i create a project, i choise a page is Ajax
but on Webconfig i add <appsetting> is error
Error 36 Only one <configsections> element allowed per config file and if present must be the first child of the root <configuration> element. C:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\WebSites\AJAXEnabledWebSite3\Web.config 8
????

Hmm, I'm going to go out on a limb here and guess that your web.config is a bit messed up. Perhaps making sure it is valid would be a start.

Hi,
I'm currently AJAX-enabling an existing project and came across the folliwing issue.
On the developer machine the whole app (localhost/appname) runs just fine, but is not reachable from remote machines (ipaddress/appname - using windows auth) - meaning the app starts, but failes to load the external ajax scripts (via ScriptResource.axd) which then results the known "Sys undefined" error message.
Same behaviour when I deploy my app to the test or production server.
I've tried to publish the web site and deploy the precompiled code but this didn't help anything. My Web.config is correct, the Script-Handlers are configured correct, etc. I really double-checked everything twice...
Any tips or hints?
