.net - Getting User Count From Database?
Jan 14, 2011
Is the following code using good practices? All I want to do is get a count of the number of rows which any given user has:
objSQLCommand = New SqlCommand("select count(id) as record_count from table1 where user = @strUser", objSQLConnection)
objSQLCommand.Parameters.Add("@strUser", SqlDbType.VarChar, 3).Value = strUser
objSQLCommand.Connection.Open()
objSQLDataReader = objSQLCommand.ExecuteReader()
objSQLDataReader.Read()

designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

In one of my school assignments I am trying to count fields (that are strings) in a database and then publish them to the screen, however I can't seem to figure out how to count them.I've been trying to do something like this but I am having trouble with the bold part. I think the datatypes are the issue but if not this then what? What is a better way to try and do this?

I am using a mysql database and I am trying to get the number of results. I should only have 1 result because this is for a username/password login. I tried this
If loginReader.HasRows Then
'do whatever here
Else
'do something else here
End If
The loginReader gets the results and does the ExecuteReader. The problem with this is that if I use a good username and password it works but if I put in a bad username and password it doesnt do either one of them. Any ideas on how to just count the number of results?

There are 3 textboxes->textbox1,textbox2,textbox3 and 1 button.In textbox1 bname will be stored and in textbox2 aname is stored.Bname and aname are columns of databasetable.This are not unique.There are same bnames and anames records.What I am trying to do is:when the user clicks on button then the code should match textbox1 and textbox2 with the databasetable and get the count of rows that match this data.
And print the count in the textbox3.If there is no similar bname and aname in the table then the count should show 0.I tried doing this but am pretty sure that its not right as its not working.

I'm using VB.NET, and I'm trying to write a program for the company I work for, that interacts with a database designed for logging web site email submissions (After a user fills out a form for a item request or comment sheet, the email the form sends gets logged so we can more easily see which site gets spammed more, and we keep a record of the actual spam). My program mainly just makes the data easier to read. However, I want to add a feature so that a user can click a button, then an automatic query will take place so that all the preserved URLs in the database are tested, then a form will appear that states something along the lines of: These Sites Sent This Number of Emails

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I'm designing a PC-based app that has a little local database. I'm using VB.NET with SQL Server Compact Edition. The user will only ever have access to one database file, because it's all about storing a user specific data. However I'm thinking of the situation where there could be multiple users that access the PC, each with their own Windows account. So ideally I'd need separate database files for each User.
I'm not sure how to implement this. I was hoping to deploy the 'empty' database as a ClickOnce deployment, but I can't see how I can have a database per user doing this. Also I'm not sure where to store the database files anyway. perhaps in MyDocuments for each user? Or perhaps I need to stick to just one database, but add a 'User' column into every table, so it can hold data for every user. I didn't want to do this though - because I wanted to keep the nice separation between the data offered by physically separate files.

I have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

Declare some class level variables that will keep track of the sums for each column. For example:
[Code]....
During the RowDataBound event, retrieve the data from each column and add it to the appropriate sum. I'm not sure if you are developing an ASP.NET application or a Win-forms desktop application so I cannot help you any further at this point. What have you tried so far to solve the problem?

I have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.
