Need Help With Late Binding On Bindingsource Field
Nov 7, 2007
This is an error that popped up with after setting option strict to on
option strict disallows late binding
The error is on the field in red
If customer_data_reader("CustID") = (customer_bindingsource.Current("CustID") Then
i was looking at this but i cannot find what type this is exactly
If CStr(customer_data_reader("CustID")) = Ctype(customer_bindingsource.Current("CustID"), ????????) Then
It is a field, but how would i set the type for this?
Or do i need to do something different?
Thanks
Jeff

My task is to add income by taking few variables from webpage. I had take User ID(From database), Field value by selecting it from DropDownBox( Which value is once again taken from database), Income Description, Date, Amount . I had completed this task successfully by binding DropDownBox to database by query string and added income using stored procedure as below.
I need this to be done using only single Stored Procedure for binding Field Value to DropDownBox and for adding income. Plz tell me how to do this?
ASPX.CS file

da.Fill(ds);
IFDdl.DataSource = ds;
IFDdl.DataTextField= ds.Tables[0].Columns[0].ToString();
IFDdl.DataValueField = ds.Tables[0].Columns[0].ToString();
IFDdl.DataBind();

Hello,
I have a report which displays a customers invoice, in both the companys local currency, and the customers local currency.
The report language is "English (United Kingdom)"
The fields showing customers currency language setting is set to something else, i.e. "France (French)" to display the Euro currency.
The application handles 34 currencies, the query returns the language string, ("France (French)"), to allow the report to bind its language setting to the querys output.
However, it doesn't work, a normal textbox will display the correct country name string, but Reporting Services cannot bind the language setting to a query result. So I also tried setting it as a report parameter, but no joy either (all currencys revert to USD).
I'm using =First(Fields!curFormat.Value, "myDataSet") to bind the 'language' setting, the result of this expression returns "France (French)", which is a valid option for this language setting, as it's in the drop down list.
Rather than create 34 seperate reports for each currency, are there any suggestions on how to bind a fields language setting to a query result?

I have an updateable and sensitive SqlCeResultSet that is bound to a DataGrid via a BindingSource. All updates to the resultset are programmatic. Changes to an existing record in the resultset are visible in the DataGrid and I am getting corresponding ListChanged events fired from the BindingSource. When I perform an database update independent of the resultset that changes resultset membership, I can peform a ReadLast and see the additional records; however the ListChanged event does not fire. Also, when I explicitly "create" a new record in the resultset I do not get a ListChanged event and in both cases the DataGrid does not display the records. Re-binding to the existing resultset does not appear to work either. Only when I create a new resultset and bind do the new or records display.
Using Compact Framework 2.0.
Any suggestions are appreciated.

All - I'm having some trouble, and I hope someone can give me some assistance. I've scoured Google, and have only found stuff similar to what I already have.
My company has an old commercial ERP package. The package has a table called 'Lot_Bin_Tran' that tracks movements of parts based on the part number and a 'Tran_code' - a one-character field that represents what kind of transaction it is (receipt, shipment, inventory adjustment, etc...). Using those two pieces of information, you can join this single table to any of the tables that hold the information (such as receipts). I tried to write a left join from my transaction table to my primary tables to look for transaction records that have no corresponding records in the primary tables. Some SQL might be helpful here...
Code:
SELECTLBT.*
FROMLOT_BIN_TRANLBT(NOLOCK),
PRODUCEP(NOLOCK),
ORDERSO(NOLOCK),
ISSUESI(NOLOCK),
RECEIPTSR(NOLOCK),
LOT_BIN_XFERLBX(NOLOCK)
WHERELBT.PART_NO = 'OUR_PART_NUMBER_GOES_HERE'
AND
LBT.TRAN_NO *=
CASE LBT.TRAN_CODE
WHEN 'I' THEN I.issue_no
WHEN 'P' THEN P.prod_no
WHEN 'R' THEN R.receipt_no
WHEN 'S' THEN O.order_no
WHEN 'T' THEN LBX.tran_NO
END
AND
((I.ISSUE_NO IS NULL) AND (P.PROD_NO IS NULL) AND (R.RECEIPT_NO IS NULL) AND (O.ORDER_NO IS NULL) AND (LBX.TRAN_NO IS NULL))
when I run this, though - I get the following message...
Quote:
Msg 301, Level 16, State 1
Query contains an illegal outer-join request.
If I change the Left join to an inner join (using = instead of *=), I get a resultset, but not the one I want (since I can't detect nulls in all tables using inner join). Any ideas on how I can restructure?
Thanks!

Hi. This SHOULD be something simple, but I am apparently missing something. I have a Users table where a user's status is a varchar(100). I'm trying to implement a trigger so that when a user's status is changed to any string other than what it was before the update the trigger would change the LastUpdated field to current date/time.
Here's the trigger, I replaced the update of LastUpdated with a simple print statement. For some reason, it seems like the trigger is firing after the update statement has committed because the values of @m_status_new and @m_status_old are always the same so this trigger always prints 'status has not changed.' What am I doing wrong? Thank you greatly for any help provided.
USE myDB
IF EXISTS (SELECT name FROM sysobjects
WHERE name = 'tr_update_users' AND type = 'TR')
DROP TRIGGER tr_update_users
GO
CREATE TRIGGER tr_update_users
on dbo.Users
FOR UPDATE
AS
DECLARE @m_status_new varchar(100),
@m_status_old varchar(100),
@m_UserID int
SELECT @m_status_new = UserStatus,
@m_UserID = UserID
FROMinserted
SELECT @m_status_old = UserStatus
FROMUsers
WHEREUserID = @m_UserID
IF @m_status_new != @m_status_old
BEGIN
print 'status has changed'
END
ELSE
BEGIN
print 'status has not changed'
END
GO

Hi,
I am sending variables from package to package by configuration parent packages in each package...
I usually set logging to text files in a certain path that should be received from the parent variable... the strange thing is that if i let the variable in the child package with an incorrect path, my package just through an error even if i am passing the variable from the parent with a correct value...
So... my question is... does my package starts execution without any synch over the parent packages? When are they set? How can i be sure to start my logging with the right parent variable settings?
You can try for example to create a package... add a new variable like "A" and "B" set its value to a default string like "I DONT WANT THIS", add an Execute SQL Task that will record the values of "A" variable to a temporary table...
Then use dtexecui.exe to execute the package and set variable "A" to "THIS IS WHAT I NEED" you will see that in the table will appear one record with the "I DONT WANT THIS" value...
I can't understand this...
Also... if i have 100 variables configured to get values from the parent... is the execution synch or asynch?
Best Regards,

Hi,Sorry for the obscure title but I'm afraid I can't think of a betterway to describe what happened to one of my clerks last night. The guy wasworking late, made a series of changes (accross a number of tables with adependant relationship structure - i.e. a customer linked to an order linkedto an invoice linked to a payments etc.) Now when he came back this morningnone of the work he did last night was still there. I'm by no means asql-pro - but I've managed to make do so far. Here's what I know:1) All of our records in all of our tables have date/time stamped. Once whenthey go in and once when they're changed. So with a little work I can buildup a good picture of what usage our database gets at what times. I've pulledup a query and there is a big fat hole between 8pm-10pm - stuff thathappened before that is still there, stuff that happened after that is stillthere - but all the changes that were put in between then just aren't thereany more. So it's not just insertions but updates as well.2) There is no perceivable break in our identity columns. So despite thefact that I know he entered 7 new customers, I can go back through thecustomers table and look at where those customers should sit visa vie entrytimes - and it's just as though the customers he entered never existed -sql server just keeps incrementing sequentially and there's no break - sothe last customer entered at about 6:50 pm was something like number 11912and the customers entered this morning have numbers that carry on from11913.3) I'm running in a shared environment - the server is hosted by awebhosting company (who shall remain nameless unless I can prove it's theirfault!) based in the US - the server has 100's of other Users databasesrunning on it.I just don't know where to begin diagnosing this sort of problem. But it hasme really running scared. It's not the first time something like this hashappened to me (i've noticed it once before when I had to get a connectionkilled by the people who manage our server because of a long-running querythat seemed to have just got bunged up and was locking a key table) - butthat was just a few records changed by the user who's connection got killed.Nothing like this... but it's pretty scary - I've got no way of knowing thatI'm losing changes like this on a continuous basis. It's my worstnightmare - like a pipe leaking underneath a floor board - and you only findout when the water starts running down the stairs!Has anyone got any ideas? Any starting places? Anyone else had anything likethis happen to them before?ThanksNick

Hey guys, Am in need of help please, basically the program im working with at the moment is when you add a New Contract, it will grab the Contract Number you have entered, Post it over to another page, then using that number bind a Gridview. The SQL being "SELECT Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent FROM ECS_Contracts_Test WHERE Contract_Number = " & conNoVar (this being the Contract Number of the recently added Contract), however then it comes to Bind the Grid it kicks up an System.Data.SqlClient.SqlException: Syntax error converting the nvarchar value
'2009P7899' to a column of data type int.But the Column Contract_Number is set to Varchar and all I really want to do is to create this gridview using this criteria and not convert anything! The Contract_ID is an int, which is needed as I increment it. Heres the error code: Public Sub BindtheGrid()'Bind the Contract Grid, where ContractID is used
Dim SQL As String = "Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent"
Dim objConn As SqlConnection = New SqlConnection(ConnectionString)
Dim cmdstock As SqlCommand = New SqlCommand("SELECT " & SQL & " FROM ECS_Contracts_Test WHERE Contract_Number = " & contractQueryID, objConn)
cmdstock.CommandType = CommandType.Text
objConn.Open()
GridView1.DataSource = cmdstock.ExecuteReader()
GridView1.DataBind()
objConn.Close()
End Sub If you need any more information then please let me know. Mucho Aprreciated

I have this stored procedure that almost works:

go
ALTER PROCEDURE [dbo].[udForumTopicMessageByForumTopicID]
@ForumTopicID int
AS
SELECT
ftm_parent.ForumTopicMessageID AS "ForumTopicMessageID",
ftm_parent.ForumTopicID AS "ForumTopicID",
ftm_parent.ContactID AS "ContactID",
ftm_parent.MessageTitle AS "MessageTitle",
ftm_parent.MessageText AS "MessageText",
ftm_parent.ApprovedInd AS "Approved",
ftm_parent.ReviewedInd AS "ReviewedInd",
ftm_parent.ParentMessageID AS "ParentMessageID",
ftm_parent.OwnerCompany AS "ForumTopicMessageOwnerCompany",
ftm_parent.CreateUser AS "ForumTopicMessageCreateUser",
ftm_parent.UpdateUser AS "ForumTopicMessageUpdateUser",
ftm_parent.CreateDate AS "ForumTopicMessageCreateDate",
ftm_parent.UpdateDate AS "ForumTopicMessageUpdateDate",
'('+CAST(ChildResponseCount As VARCHAR(10))+')' As "ChildResponseCount",
(T_Contact.Lastname + ', ' + T_Contact.Firstname) As "ContactName"
FROM [T_ForumTopicMessage] as ftm_parent
INNER JOIN [T_Contact] ON [T_Contact].ContactID = ftm_parent.ContactID
Left JOIN
(Select
COUNT([T_ForumTopicMessage].ForumTopicMessageID) As "ChildResponseCount",
MAX([T_ForumTopicMessage].ParentMessageID) AS "ParentMessageID"
FROM
[T_ForumTopicMessage]
WHERE [T_ForumTopicMessage].ParentMessageID = ftm_parent.ForumTopicMessageID
group by [T_ForumTopicMessage].ForumTopicMessageID)
as ftm_child ON ftm_parent.ForumTopicMessageID = ftm_child.ParentMessageID
WHERE ftm_parent.ForumTopicID = @ForumTopicID
ORDER BY ftm_parent.CreateDate
See the purple ftm_parent.ForumtopicMessageID. If I hard-code that to a 2, this works. With the fieldname there, SQL Server Management Studio says:
Msg 4104, Level 16, State 1, Procedure udForumTopicMessageByForumTopicID, Line 9
The multi-part identifier "ftm_parent.ForumTopicMessageID" could not be bound.
If any experts out there can help me out with this, I'm sure it wouldn't take much to fix.

I am new to .net and I am using Visual Web Developer 2005 Express with SQL Server 2005 Express. What I would like to do is connect to my SQL database (which resides in the app_data folder) and open a table and pull out a field and place it in either a textbox or label on the page. No editing or deleting. Just simple one field binding. By the way, I can do this with all the cool built-in tools of VWD, but I want to know how to do it all by hand. I would really appreciate it if someone could help me out.

Database2:Table2(Name,Number)
Output in Gridview:
callingPartyNumber
Name
originalCalledPartyNumber
finalcalledPartyNumber
dateTimeConnected
dateTimeDisconnected
Duration (HH:MM:SS)
I bind gridview programatically using DataTable and stored procedures. The data comes from a table (Table1) in a database (Database1) on SQL Server. The gridview displays fields callingPartyNumber, originalCalledPartyNumber, finalCalledPartyNumber, DateTimeConnect, DateTimeDisconnect and Duration in this order. All the columns in this gridview are databound columns.
I have another table (Table2) in a seperate SQL Server database (Database2) but on the same server which maps the callingPartNumber value with the name attached with that number. Note that the field names in Table2 are different from the field names in Table1. Is it possible to display the Name field also in the gridview after the first field callingPartyNumber and then the other fields.
Its like data coming from two tables into the gridview.
Thanks

Hi all. I have a label on my page and I want to bind it to a field in a table. The catch is that I want to bind it to the last row in the table. I think I can use the custom binding, but I don't know how to bind to the last row. Any Suggestions ?
p.s. The page is tied to an SqlDataSource that retrieves the data from the above table.
Thanks in advance.

Hi, I am using a SQL DataSource with a few parameters. I need to specify the value of the parameters at run time but I need a custom way to do it as the value needs to be calculated not come from Cookie, Control, Form, Profile, QueryString or Session. Is there a way to bind your own value to these parameters. For instance if I had a variable how would I bind that to the parameter?
At the moment i am doing the following which works but I dont think it is the correct way
dsMyDataSource.SelectParameters["MyParameter"].DefaultValue = MyCalculatedValue;
In previous projects i have added a value to the Session and then bound the parameter value to the session but that doesnt seem like a good solution either.
Thanks for any help you can give.
Martin

Hi All
I am new to VS 2005 and ASP.NET. I used to use Dreamweaver to design but now I am trying VS.
What I want to do is to display data retrieved with a SqlDataSource in a web page. I know how to do it by binding it to the various controls (Grid, DataList, DetailsView, FormView, Repeater.) available but how can I display it without using any of the mentioned (Grid, DataList, DetailsView, FormView, Repeater)?
Any help apprecited.
