I have a list of several people by username and email that I will not help ever. PDNET is right at the top =P
Any suggestions, ideas, or 'constructive criticism' are always welcome.

I wrote down the member #s as well incase they changed their name (might be hard to tell initially, but their stupidity will probably give them away again).

Hi all...
I am creating a simple database application program. I used VB.Net (VS2005) as frontend and SQL Server 2005 as backend. Now each time I run insert,delete or update query, it runs fine and shows changed made in application but it does not make permanently changes in database.
Suggest me what should I do to make permanent changes in database.
Thanks.

How are you doing this? Post some code.
Are you updating the database? Unless you do this, you will see the changes in dataset but not in DB.

code is :
imports system.data.sqlclient
try
dim str as string="update tblLogin set Uname='" & txtName.text & "',Passwd='" & txtPasswd.text & "'"
dim cmd as new sqlCommand(str,con) 'Con is declared as public sqlConnection
connectToDatabase.Connect() 'It is a method used to open connection if it is closed.
cmd.ExecuteNonQuery()
msgbox("Sucess")
catch ex as exception
msgbox("Error is : " & ex.message)
end try
'end code
Now the above code shows message "Sucess",it means query run sucessfully but it does not change actual data in database.
Suggest me what should I do now.
Thanks for quick reply.

1. Check the returned value of ExecuteNonQuery statement.
2. Check the connection string if that is pointing to correct database and you are checking the same.

The returned value of cmd.ExecuteNonQuery is 1.
I have also checked database connection string and test connection with database.Everything is ok but query is not making permanent changes in database.
What should I do now.
Thanks.

David and d@nish both have good suggestions.
Here's one for ya. If the query looks ok and there isn't an obvious error - run profiler.
Open up SQL profiler and examine what's being sent to SQL server. Profiler doesn't lie and quickly will 'highlight' what the problem is. If the query is making it to the server - ensure it's hitting the right database (if the connect isn't making it, then it's a connection problem of some kind probably).
If it is making it, copy and paste the SQL statement being sent into a query window in SQL Management Studio and try to execute it. If there are errors fix them in the query window and re-execute to verify. Since your problem is that it's not updating the database, add a select statement at the end to verify the records are being updated. If correct, then update your source in VB. Also check your where clause and make sure your updating the right records. If there is transaction logic, it'll be shown (although possibly split on multiple lines in profiler).
IMO: Profiler is one of the best benchmarking and diagnostic tools for SQL.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

He may have thought it was built into Database management studio (although you can launch it from there too under tools).
Everybody has their off days (god knows I do) - lol.

That is the reason I replied like that. One might find it rude.
If someone is using Management Studio, he/she must have seen tools menu atleast once.

No problem Gagan,
Start Menu -> Progs -> MS SQL Server 2005 -> Performance Tools -> Profiler.
Quick and dirty usage (later, you really should learn the ins and outs of this tool - it's worth its weight x 100).
Start it up. Select the server that this query should be going to. Select the default trace.
A trace will start running reporting everything on the DB. If there are multiple devs/users using the server, then a crap load of events will be displayed rapidly.
Pause the trace (button on the toolbar ||). Put a breakpoint in VB where your CMD is about to execute. Go back to profiler, press Start |> Execute your SQL command and then repause Profiler. All the lines you see are the raw statements being sent to SQL server. Look for your update statement and copy that out to a query window. If nothing is there, prob. a connection issue of some kind.
Once you get used to profiler you can create specific traces by DB, users, events, etc.
Hope this helps ya out bud.

If you are performing these updates inside a transaction, then you have to make sure that you perform a commit.

I have a .txt file.
i want to read that .txtc file as a DataSet
any help on how to do?
|
|
|
|
|
Create OleDbConnection to it and the fill the dataset as done with any database table. Or use methods in File class and manually fill the dataset.

What do you want to do? Write data to text file or read data from text file?

Hi all... I'm working on a report (Reporting Services) with an external image. The problem is it's not showing up. I'm passing the image through as a base64 string to the report and converting it back to bytes using the Convert.FromBase64String function. The code is as follows
Dim location As String = Configuration.ConfigurationSettings.AppSettings("location")
Dim reader1 As New System.IO.StreamReader(location)
Dim base64 As String
Dim BinRead As New BinaryReader(reader1.BaseStream)
Dim file1 As New FileInfo(location)
base64 = Convert.ToBase64String(BinRead.ReadBytes(CType(file1.Length, Integer)))
Dim param As New Microsoft.Reporting.WinForms.ReportParameter("Image", base64, False)
Dim al As New List(Of Microsoft.Reporting.WinForms.ReportParameter)
al.Add(param)
ReportViewer1.LocalReport.EnableExternalImages = True
ReportViewer1.LocalReport.SetParameters(al)
ReportViewer1.RefreshReport()
.
.
.
Please ignore the BinReader / Reader bit. I havn't fixed that up yet. If someone can please tell me why this thing is not showing an image. I would be very greatful.

I'm a little confused on your post, but I'll give it a shot.
You could read the entire file into a stringbuilder and then do the concatenation at the end or you could read the file in line by line and combine the fields. Once the string builder has been modified with the changes you want, write it back out to the new file. You'll want to use something like the stringbuilder since strings are immutable.
If there are field headers at the top of the file, you'll want to remove the AEC_COMPATIBILITY header.
Any suggestions, ideas, or 'constructive criticism' are always welcome.
