Same Exact Code Works In Vb.net But Not In C#
Feb 9, 2006
can any help me why the same exact code works in vb.net but not in C# . case is very simple
I have a table called MenuItems which has menu items and a table sizeandprice which has price for each menuitem based on the size. simple case of 1 to many relationship between menuitems table to sizeandprice table. I am trying to display in a gridview control couple of fields from menuitems table and have another template field in which i am display price and size field from the child table which is sizeand price. so basically this is how my code looks like
Page in vb works fine

Hi,
Is there a better (more elegant) way to build the file name than the following code:
/* File name has format mmddhhmmDX.748 with all time/date values zero padded */
DECLARE @FileName char(14)
DECLARE @out_dte datetime
DECLARE @CharDate char(8)
DECLARE @CharTime char(8)
set @out_dte = '2006-08-03 04:05:12.670'
set @CharDate = convert(char(8),@out_dte,1)
set @CharTime = convert(char(8),@out_dte,8)
set @FileName = substring(@CharDAte,1,2) +
substring(@CharDate,4,2) +
substring(@CharTime,1,2) +
substring(@CharTime,4,2) +
'DX.748'
select @FileName
/* Expected Result: 08030405DX.748 */
My first attempt was this:
DECLARE @FileName char(14)
DECLARE @out_dte datetime
set @out_dte = '2006-08-03 04:05:12.670'
set @FileName = cast(DATEPART(mm,@out_dte) as char(2)) +
cast(DATEPART(dd,@out_dte) as char(2)) +
cast(DATEPART(HH,@out_dte) as char(2)) +
cast(DATEPART(mm,@out_dte) as char(2)) +
'DX.748'
select @FileName
… but then date and time values were left justified spaced filled.
Example output: 8 3 4 8 DX.748
I don't just want to get code that works. I want to learn how to write the best possible code.
Thanks,
Laurie

Hi;
I wanted to use the following code to run a DTS package from a 2005 Web Page code behind partial class. This code works fine in a VB 2003 module
going against SQl Srvr 2000.
Here is the code: (It initiates from a button click handler)
Dim conn As New SqlConnection("initial catalog=MY_Data;server= XYZ081552X7X441TRSQL;integrated security=SSPI")
Dim hold1 As Integer
Dim hold_source As String = ""
Dim hold_desc As String = ""
Try
conn.Open()
Catch ex1 As Exception
MsgBox("The Test connection failed to open" & vbCrLf & ex1.Message)
End Try
MsgBox("About to create a DTS object")
Dim oPackage As New DTS.Package2Class (Compiler doesn't like this line) Type DTS.Package2Class is not defined.
Dim oStep As DTS.Step (Or this one) Type DTS.step is not defined.
oPackage.LoadFromSQLServer("XYZ81552X7X441TRSQL", , , DTS.DTSSQLServerStorageFlags.DTSSQLStgFlag_UseTrustedConnection, , , , "cpyPrinters2Excel", )
For Each oStep In oPackage.Steps
oStep.ExecuteInMainThread = True
Next
oPackage.Execute()
For Each oStep In oPackage.Steps
If oStep.ExecutionResult = DTS.DTSStepExecResult.DTSStepExecResult_Failure Then
oStep.GetExecutionErrorInfo(hold1, , )
Else
End If
Next
oPackage.UnInitialize()
oPackage = Nothing
conn.Close()
Has Microsoft changed the DTS objects so that they work only with SQL Srv 2005 ?
Thanks for your insights.

Hello
The following code does not function if I use SQLOLEDB if I omit the provide and default to ODBC OLE DB it works correctly. I am assume I am coding something wrong for a SQLOLEDB provide. Any help is greatly appricated.
VB Code
Public Function SqlExecuteResult(xSQL As String, sServer As String, sDatabase As String, sUserName As String, sPassword As String, sCaller As String, Optional bLog As Boolean = False) As Object
Dim oDB As Object
Dim oRS As Object
Set oDB = CreateObject("adodb.connection")
Set oRS = CreateObject("adodb.recordset")
oDB.open "driver={SQL Server};provider=sqloledb;server=" & sServer & ";database=" & sDatabase & ";uid=" & sUserName & ";pwd=" & sPassword & ";"
oRS.CursorLocation = adUseClient
oRS.CursorType = adOpenStatic
Set oRS.ActiveConnection = oDB
oRS.open xSQL
Set oRS.ActiveConnection = Nothing
Set SqlExecuteResult = oRS
oDB.Close
Set oDB = Nothing
End Function
Private Sub Form_Load()
Dim rs As Object
Set rs = SqlExecuteResult("exec NextEntry 'SentMessages'", "surecomp-bob", "pmsureus33", "sa", "", "")
MsgBox rs.fields(0)
End Sub
SQL proceedure
CREATE PROCEDURE NextEntry @CounterName Varchar(20) AS
begin
declare @counter int
select @counter = counter from counters where countername = @counterName
select @counter = @counter + 1
update counters set counter = @counter where countername = @countername
select counter from counters where countername = @counterName
End
GO

hi,
Can I write a dll(or share the same code) that works on both Mobile device and pc? Since we are using compact edition, we are hoping we can write some common module with the same code that could works on both mobile device and pc platform. I noticed the reference is the same, System.Data.SqlServerCe.dll 3.0.
Another question is, we already have a module for SQLCE2.0, with .net CF1.0. Now, we will start to use compact edition, should we just update on the 1.0 one, or we have to write a different one based on .net CF2.0? Can I use compact edition in CF1.0 dll?
Thanks.

hi,
I have a custom code that can gets string from an array:
Public Shared FormatArray() As Object
Public Shared Function GetFormat(ByVal _Col As Integer) As String
Return FormatArray(_Col)
End Function
However if I place the code in a Table details value expression =Code.GetFormat(0), It will give me #ERROR
But if I put in the Table Header row value, then it shows me the String correctly, same for in Footer of the table.
Its only within the details rows that is not working
Does anyone know what is the problem??
many thanks

Can i have a combination of sources some with Unique Identifiers and some without?
I need to know what happens when I have option “Create Code values automatically” selected for the entity and same time pulling Unique Identifier for other sources in same entity stage table.
When we select option “Create Code values automatically” for the entity we creates, then during load from external source to MDM stage we don’t send any values to MDM stage “Code” field and in next step when we execute the stored procedure to load the data from MDM stage to MDM model, it assigns the Code values to each record in MDM stage and MDM model.
I need to know whether after executing the store procedure, will it assign Code values for only NULL records in MDM stage and not give us any error for the records that already have Code values present in MDM stage.

That I am calling from a textboxes in the page header
= Code.GetDealCount(ReportItems) & " Deal(s)"
also
= Parameters!BaseCurrency.Value + " " + Format(Code.GetSumNotionalAmount(ReportItems),"N2").ToString().Replace(",","'")
When I preview the report in VS.NET I get values showing.
When I deploy the report I just get #Error showing.
Also this report used to work fine in RS2000
Does anyone know the cause of this issue?

We have a Process Task component setup in a couple SSIS jobs to call a command batch file to support transfering a file via Secure FTP to other servers and the process works fine if we start the SQL Agent job manually, however when the job is started via the scheduler, it fails with an exit code of 4. Even though there is a proxy setup on the agent job, is there a different user account being invoked by the scheduler??? We're on 2005 SP1 Hotfix 1 (2153). Thanks
Some more info...have found that if we leave a login session open on the server (login is the proxy account) the process works. It appears the issue is associated with a need to render/create a command window for the command line/batch process to run in and without an active windows session it fails....would seem to be that a product setup to run on a server in a batch mode would be able to work without this...is this the case? if so, how? Thanks.

I'm having a strange problem with this but I know (and admit) that the problem is on my PC and nowhere else. My firewall was causing a problem because I was unable to PING the database server, switching this off gets a successful PING immediately. The most useful utility to date is running netstat -an in the command window. This illustrates all the connections that are live and ports that are being listed to. I can establish a connection both by running
telnet sql5.hostinguk.net 1433 and
sqlcmd -S sql5.hostinguk.net -U username -P password
See below:

Both these utilities show as establishing a connection in netstat so I am able to connect the database server every time, this worked throughout yesterday and has continued this morning.
The problem is when I attempt to use SQL Server Management Studio. When I attempt to connect to tcp:sql5.hostinguk.net, 1433 nothing shows in netstat at all. There is an option to encrypt the connection in the connection properties tab in management studio, when I enable this I do get an entry in netstat -an, see below:
TCP 81.105.102.47:1138 217.194.210.169:1433 TIME_WAIT
TCP 81.105.102.47:1139 217.194.210.169:1433 TIME_WAIT
TCP 81.105.102.47:1140 217.194.210.169:1433 TIME_WAIT
Amost as if it's trying the different ports but you get this time_wait thing. The error message is more meaningful and hopefull because I get:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (.Net SqlClient Data Provider)
I would expect this as the DNS has not been advised to encrypt the conection.
This is much better than the : Login failed for user 'COX10289'. (.Net SqlClient Data Provider) that I get, irrespective of whether I enter a password or not.
This is on a XP machine trying to connect to the remote webhosting company via the internet.
I can ping the server
I have enabled shared memory and tcp/ip in protocols, named pipes and via are disabled
I do not have any aliases set up
No I do not force encryption
I wonder if you have any further suggestions to this problem?

I'm currently working on a match function to compare two char based columns in differnet tables to create a join.
In this particular case, I'm using a few different approaches to create a higher match ratio, as typos do happen.
For instance I use a join function using convert(char(10), tbla.field) = convert(char(10), tblb.field) to match only using the first 10 characters, as a lot of records have different endings, but are in fact the same.
Are there any other ways I could attempt to make matches? I was wondering if there was a dedicated string comparison operation giving me a percentage feedback. Debut joining dbut would give an 80% match, and thus I would leave it up to the user to decide to minimum match requirements.
Thanks in advance

I've a table with values that have the '-' char, ex:LO-AS-1.I'm trying to search the table for that value but it returns more records since it breaks the search term into several others:
SELECT * FROM sys.dm_fts_parser ('"LO-AS-1"', 2070, 0, 0) returns:
lo-as-1
lo
as - noise word
1 - noise word
nn1 - noise word
Is there anyway of searching for the exact word? With LIKE it works fine but it's very slow....

Hi.
I have some contracts and i want to find for every specific contract (every contract can be repeated 2-3 or more times (same policynumber) the contracts that have the same date. That's the contracts INSIDE the contract that have the same data.
I was trying something like
select distinct m.masterpolicyno from multicontract m
where m.category=3
and m.issuedate = m.issuedate
but it think i must use "having" and "in" but i can't figure it out.
Any help?
Thanks.

For a long running stored procedure, how can I determine the SQL statement within the stored procedure that is currently running?
The Activity Monitor only shows the name of the stored procedure and whether it is a SELECT/INSERT/UPDATE, never the complete statement.

In one of my packages, I am trying to create functionality that is similar to the fuzzy grouping transformation in that it takes a set of records and returns a subset of unique records. However, rather than fuzzy-matching columns which creates significant overhead, I just want to compare columns exactly, similar to how the lookup transformation works. At this point, data has already been fuzzy unique/duplicate seperated, this step is to only keep one record for each exactly similar dupe for an alias table.
At the moment, I am doing this (with lack of scalability foresight) with a fuzzy grouping transformation with all columns set to exact except for one which is set to fuzzy with a minimum similarity of 0.99. While this worked during development when I was testing with a small subset of data, it is unreasonable for the ~5mil records of production data it needs to operate on.
I am sure there is an efficient way to do this. I have thought about using a lookup transformation or combinations thereof, but I have not come to a definite solution yet.
Does anyone have any experience doing something similar to what I am trying or have any suggestions/ideas/questions/etc? Any help will be greatly appreciated.

Hello All,
I'm looking for a TSQL function or technique that when provided a date time as string and also a format, it must return a valid tsql datetime object/variable.
for example somethig like
GetDateTime('20071010', 'YYYYMMDD') or GetDateTime('10/10/2008', 'MM/DD/YYYY')
Essentially I want to get away from Implicit conversion from string to datetime. I want better control over this to ensure we dont run into any issues when our code runs on systems configured to be on various cultures.
I can even live with a few fixed formats and not being able to support arbitrary formats.
Any help/ideas/advise will be appreciated.

I am not sure how to go about doing this. I have a record that has a start time of 1 am and a stop time of 9pm (same day for simplicity) and I want to know how many hours during a peek time and how many were not.
For example, the application starts and inserts into the data base the start time of 1am and then the user stops the app at 9pm. Lets say the peek hours are 1pm to 7pm. I know i can do a date diff function to get how long the app ran for but how can I get the amount of hours it ran during the peek time? I know there has to be some mathematical solution to this but it is escaping me at the moment. I want to do this over many records so a a cte or pivot table is the end solution for performance.

Hi can anybody give me a simple example to check exact match word using sql sever
Ex: my word is like this : welcome to sql sever2005
Now i want to find server how it is possible?
I tried like this
select * from test where content like %server% . but is gives me possible result. But i dont want like this if i have an exact match with that key word then only i want possitive result.
Actually there is no word with server, i'm having only server2005 . So how can I get it?
Thank you

Hi,
This is strange....
I am getting my source data from another system am storing the SaleAmount of each product in a field the data type of which is [decimal](12, 2).
For some products I am getting an exact match (upto 2 decimal places) as compared with my source data BUT for some other products the value before the decimal places is correct but the 2 digits after the decimal place does not match with the source data :confused:
Even if this sounds stupid, can you please guide me. Am i missing some very basic and common sense thing?
Many TIA.

I have to find the number of orders sent to two different postal codes but to get all of the right columns, I have to use 2 different tables.
So, I used WHERE to connect the two tables with the primary keys, but where do I use the specific criteria for the exact postal codes?

I have a report that displays many duplicate rows where all fields in several rows are exact duplicates. I would like to know how to make it so that the entire row does not show up if it is an exact duplicate of another row. Any ideas? Thanks.

In my SSIS package I have a text file source that I am mapping to a destination table. I have an error component that logs any row level errors and have noticed that it is not logging the correct field. I know this because I have a few different sources that submit the same files and have looked at the source of both. THE ONLY DIFFERENCE in the one that works versus the one that does not is that 2 of the 25+ columns are switched. I would not think this would matter because field A in the text file is mapped to field A in the database.
Does the order in which the fields come into the SSIS package matter?
Thanks
