How To Avoid Replication Of Data In DataGridView
Jun 30, 2011
I am developing VB.Net application, here I am using DataGridView control to display data from database now it is displaying as follows
Emp no Emp name city Sal Description Salary
54 john NJ HRA 1000
54 john NJ DA 2500
54 john NJ BP 12500
But I need to display as follows
emp no emp name city Sal Description Salary Net Sal
54 john NJ HRA 1000
DA 2500
BP 12500 16000
Since emp no, emp name and city is repeated I need not to display it again and net salary too should be displayed in the third row by adding HRA+DA+BP.

I don't know if my question is sql server related or vb.net or both. so I will ask it here. Let say I have 3 sql servers with replication among them connected together by vpn. let say i have a customer C1 exist on first server S1 and his account is 1000$ which is the same on second server S2 on S1 they enter a new receipt, so the customer C1 on S1 balance became 1100$ while it still 1000$ on S2, and it need 1-2 min for the replication to finished if during this 1-2 min, S2 is entering invoice, C1 balance will show 1000$ while it is actually 1100$ (because the replication did not finished yet) My first idea is to make sql query getting the customer balance from 3 servers and compare them. How I can tell that the customer account are not the same on both servers or check if the replication is finished for that table holding the customer balance?

I am trying to place a repeater within a repeater using xml data. I have it working exactly as I want, but the method I have used reloads the data for each repeater. I think I need to cast as an XmlNode but I'll be honest - I have no idea where to start. Here is my code - I'd like to keep everything in the code behind if possible.

I'm planning to create an VB.net application for retrieving data from a database (MS Access) and store it to a web server (MySQL data base). I really have confusion in my mind. I'm planning to use task scheduler so that the program will automatically run. I'm planning to set the time every 5 minutes.How can I avoid the redundancy of data? For example, I'm planning to get the sales for 5 minutes, after 5 minutes I will do it again. I think there will be redundancy in that case.

- I'm working on a windows forms application (.NET 4.0). - My form contains a 'Fast Line' chart using the Microsoft chart control included in VS2010. - The chart gets filled with about 20,000 datapoints. - My application then starts receiving market data from a server via DDE (Dynamic Data Exchange) in real-time and adds it the chart.
Note: I have no control over the server and so I have to deal with DDE only even though it's an outdated technology. VS doesn't support DDE anymore and so I use the Ndde library which works like a charm.
Private Sub StartDDE()
'first we connect to the DDE server:
Dim client As DdeClient = New DdeClient("ServerApplication", "Bid")

I want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.

I have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using
Me.table.Update(Me.FigsDataSet.table)
Me.Validate()

I am trying to click on certain rows in a datagridview and have the information in the rows sent to a textbox. It does not append each row to the textbox though, which is what I want it to do. it just replaces it with the row I click on. What's wrong with my code. I have tried cell click too.
Private Sub dgProducts_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles dgProducts.Click

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.

Until asking a question on here I never considered (enums) to be a "bad thing." For those out there that consider them not to be best practice, what are some approachs/patterns for avoiding their use in code?
Edit:
public Enum SomeStatus
Approved = 1
Denied = 2
Pending =3

I am doing an activation server which will enable users to activate their software. The problem is that they own the public key.. the verification method needs the public key to check signature of the license file. My concern is that someone could generate their own license file using two key (public and private) and then change the public key on the client which would spoof his current license.
Is there any way of avoiding this ? Where should the public key be stored ? You have to take into consideration that the checkup is done on client and the signature is created on server.
