I have following issue: I have a datatable with a column which I would like to encrypt. This table has about 10.000 rows, and this particular column is storing 14 digit keys. Is there any way to encrypt all those keys in this particular column (just to make them useless if someone steals by db)?

View 1 RepliesI have a DataTable which having some rows which bind from database. I would like to add some new rows to that datatable.
I used the following code.
conn.Open();
SqlCommand cmdDownload = conn.CreateCommand();
cmdDownload.CommandType = CommandType.Text;
cmdDownload.CommandText = "select SKUCode,'Image Available' as [Status] "
+ "from tblName"

But the new rows are not adding to the datatable.
Below is a beginning attempt to increment through a DataTable populated by a Stored Procedure and create a new DataTable where every Category is represented by exactly four products. I need to add dummy product entries for some and skip over those with over four products.
A) - I think I understand the basics but this builing from scratch is not my practice.
1) I do not know how to query a previous row in reference DataTable.
2) I do not know how to jump to next row from IF construct.
3) I hope I am able to build a DataTable row by row.
4) Partial sample data is at bottom of pseudo code

I am adding a new language Fr-FR in the code above. fr-FR already exists in my DB's Language Table. I do not want to add duplicate values in my table. There should be only one fr-FR.
I have created a datatable with three fields namely TimeTask, TaskItem and Count (count of user) eg; {"12:30AM-01:00AM" , T1 , 3}.
dataTable.Columns.Add("Task Time", typeof(string));
dataTable.Columns.Add("Task", typeof(string));
dataTable.Columns.Add("Count", typeof(int));
dataTable.Rows.Add("12:00AM-12:15AM", "T1", 6);
dataTable.Rows.Add("12:45AM-01:00AM", "T1", 5);
dataTable.Rows.Add("01:00AM-01:15AM", "T1", 1);
dataTable.Rows.Add("01:15AM-01:30AM", "T2", 4);
dataTable.Rows.Add("01:30AM-01:45AM", "T2", 9);
GridView1.DataSource = dataTable;
GridView1.DataBind();
In this there is no task for the TimeTask "12:15AM-12:30AM" and "12:30AM-12:45AM" yet the TimeTask should be inserted as,
TimeTask TaskItem Count
12:00AM-12:15AM T1 6
12:15AM-12:30AM - -
12:30AM-12:45AM - -
12:45AM-01:00AM T1 5
01:00AM-01:15AM T1 1
01:15AM-01:30AM T2 4
01:30AM-01:45AM T2 9
How to chk for the missing rows? Is it possible to dynamically insert rows in an existing DataTable (No DataSource used) in this scenario.
I need to add rows to an existing (maybe) datatable in a dataset that combines the IIS6 index search with my own sql table. I keep getting object reference errors.
[Code]....
I have a dataset that has around 5 rows. I also have another Datarow() array that has an additional 3 rows which I would want to add to the dataset. The structure of both the Dataset Rows and the Datarow arrays are the same.
Do I have to perform a loop on the datatrow arrays and add them one by one? or is there a better way of adding them in one go ?
Scenario: we have a ERP software developed in ASP.Net and SQL Server 2008 as database.
Requirement: we need to encrypt / decrypt the data in the SQL Server so that only my application can read the data, How can I get this task done.
I have one problem with my shopping cart that I really can't figure out all by myself.I want, if a item already exist in the datatable, the quantity to be updated for that item with the new number instead of creating the same item again.I have done a foreach loop because I think that is where I should start.Notes: MyRow[3] is the column holding the quantity.Code:

I have two sql tables.
- (Fields:PersonID, FirstName, LastName, Role, Department)
and
- (fields: PersonID, Unit).
I want to merge those with a single table ( Fields:PersonID, FirstName, LastName, Role, Department, Unit). How can I query to accomplish this so that same personID data go to same row ? ANY QUERY ?? (I have an idea : both export to excel and merge into a single excel file and import to SQL table but due to very long data it was truncated last time when importing so I don't want to reimport again.)
'DataTable' is an ambiguous reference between 'System.Data.DataTable' and 'Microsoft.Office.Interop.Word.DataTable'
View 3 RepliesI use MS SQL SERVER DB to store some servers' info with help of ASP.NET application and I want to know the strong way to encrypt and decrypt server's passwords and store them in that DB.
provide me the way in details + code since I didn't deal with encryption before..
While sending password value from client side to server side i need to encrypt textbox value using javascript and receive that encrypted value in the server side. Here in the link you'll find one example which will send encrypted value of textbox from client end to server end. I'm trying to implement the same code, but this doesn't send encrypted textbox value from cilent side to server side. I do google regarding this, but no positive result found till now.

I have a datatable for which i'm defining a dataadapter. I'm specifying an updatecommand with sqlparameters for the dataadapter I set the updatecommand's parameters using the following overload:
[Code]....
The length 16 is used because this is the length of the field according to sql (the image datafield is a pointer of size 16) I noticed .Net is actually truncating the string because of the length i'm setting. An image of size 3kb will properly upload if we set the length field to be greater than 3kb The question I have is what is the proper value (or strategy) to use in order to set for the length field so that ALL images will properly update to the database, with each using the appropriate size.
I guess i could theoretically set the length to be maxint, but this seems sloppy. Looking at sqlparameter documentation i didnt see an 'unlimited' or 'default' length i could set, which would allow each update statement called to use the appropriate size for the data length for that row.

I have an application in Asp.net and using sql server to store user information. There is a table named dbo.member which stores user information - fname, lastname, email, phone etc. We use LDAP for authentication. The entire application works on this member table. There is a unique userid(not password) associated with each member. I installed default aspnet_membership, aspnet_role tables by running aspnet_regsql.exe utility. Now with increasing number of applications, handling members' information is becoming nightmare. I hope Membership providers will solve this problem but I have doubts.
How can I integrate existing member table with default aspnet_membership table? Or should I integrate since it is very limited? Same is the case with aspnet_Profile - it is very limited and I have stored all profile information into member table. We store more information and we want to query all that information for a user. Should I create my own provider that will use dbo.Member table instead of dbo.Membership table and also with Profile provider?
What changes to the function below are needed to achieve those requirements:- If you pass the same date, then 1 will be returned as the number of days- Return '5' when passing 18.10.2010 to 22.10.2010 (Mo-Fr.)- Return '0.5' when passing same date with (n) hours difference e.g. from 18.10.2010 08:00:00 and 18.10.10 12:00:00 (maybe I should ask start a new threand for this last one)

I can't for the life of me remember how to do this and I'm sure someone will answer this pretty quickly. I need to insert or update a record based on if it exists so in the SP I need to do:
SELECT * FROM table1 WHERE LinkedID = @ID Then I need to check if any rows were returned and apply it to an if statement which is where my mind is blocked.
