Deployment + Vista
We use strongly typed datasets, and thus our connection string is bound to
an application setting.
Currently we can deploy and alter the app.exe.config file at installation
time to successfully install, and use some basic XML editing to allow the
target database to be changed.
Writing to the application directory in vista will throw compatibility
errors, and not persist the changes at all.
What do we do? Is there a better way of getting the connection string in
your application, or a way of telling the designer where to get your
connection setting from?? Tag: Microsoft Training/ Certification Dumps /Materials Urls Tag: 138087
Eliminating CRUD procedures
Your know the ones, you have a table and it has Create,Read,Update and
Delete Stored procedures and the app always uses these to talk to the DB
eliminating dynamic sql in your apps.
Makes perfect sense when you have a table however when you have 500 tables
its not so clever (thats 2000 stored procs to maintain)
Shouldnt the framework and sql guys talk to each other and come up with a
single proc that accepts the CRUD as an argument to a single UpdateMyTable
proc for each table. Then Hey presto 500 tables = 500 procs
It would be nice if i didnt have to code it myself and the dataset wizard
just happened to offer this option in the next framework version!

Writing xml file from dataset different than the original
Hello all.
I'm reading the data from an XML file similiar to below, using the
code below. When the
file is edited in the datagridview and then re-written, it doesn't
write the xml
file as it was originally written.
So what am I doing wrong? My code and samples are below. Any help
would be greatly appreciated!!
VISUAL STUDIO 2005

Declare a bindings source, a dataset, a binding navigator, and set up
a datagridview where the

'now associate them

'Now read the xml file into the dataset &
ds.readxml(filename)
ds.ReadXml(My.Settings.configFile)
bndgSrc1.DataMember = "pnum"
bndgSrc1.ResetBindings(False)
I save the edited info as below:
dgvConfig.EndEdit()
bndgSrc1.EndEdit()
If ds.HasChanges Then
ds.AcceptChanges()
ds.WriteXml(My.Settings.configFile, XmlWriteMode.WriteSchema)

Insert a whole datatable
I have two access database (with identical schema). One is the master
and the other is SHOULD be a subset of master data (Let call them
MasterDB and SubDB
The user enters data into the SubDB and I need to bring the new
changes to the MasterDB. Traditionally, I can get a the new changes
(into a dataTable). Loop through all the rows and insert them into the
MasterDB ONE AT A TIME.
My question: IS THERE A BETTER WAY?
For SQL Server, there is a SqlBulkCopy but I am dealing with MS
Access.
In my case, performance is not an issue, I just want write less
code.

Some ADO.NET Mobile Advice please.
Hi all
I am building an Windows Mobile 5 forms control in C#, for a Windows Mobile
5 application. I am using CF2.0 and SQL Mobile 2005.
The control is a Questions and answer control.
Basically I have 3 applications using the same code to dynamically display
questions and save the answers.
I am trying to consolidate it all into 1 control for easer maintenance.
I need to pass the control the questions and meta data for the questions.
And when the last question has been completed the control should hand back
the Answers for saving.
What is the best why of doing this? I really would like to get this right
the first time.
I know I am developing with the CF2 platform. So I am concerned about
getting the most efficient why of doing this.
Possible scenarios I are.
1.. Pass the control a Questions DataTable and an Answers DataTable (Flat
File), use the Questions DataTable to load up an array and loop through the
array asking questions and saving the answers to Answers DataTable. When
the Questions are finished raise an event handing the Answers table as an
Event Arg.
2.. Pass the control a QuestionsAnswers DataSet with a Questions DataTable
and an Answers DataTable in it, use the Questions DataTable to loop round
asking questions and saving the answers to Answers DataTable. When the
Questions are finished raise an event handing the QuestionsAnswers DataSet
as an Event Arg.
3.. Hand the control a Connection and get it to read the questions
directly from the Database and save the answers directly to the database.
I really am lost.
I don't what to take the wrong path and I don't have enough background
experience to make an informed decision about what the best way to handle
this with ADO.NET and the CF would be.
Any suggestions would be welcomed.
Thanks,

Datatable
For i = 0 To dtSubOpt.Rows.Count - 1
intOptNo = dtSubOpt.Rows(i)(1)
strSelectSubOpt = "select tblOptions.strOptName as
OptionName,tblOptions.intParent ,tblMOMT.strMOTag as

where intParent=" & intOptNo & " order by OptionName"
dtOptName = dbCon.GetRecordSet(strSelectSubOpt, "tblOptions")
Next
In my above coding i need to keep all the records retrieved through
looping the query in the same datatable.
In my coding every time intOptNo has changed and retrieve the records
corresponding to that particular intOptNo . The loop executed every
times and get the records ,but the records overwrite the records
already in a datatable this is my problem .So to avoid this I need to
increment the index of the datatable row .But I don't know how to
change the row index depending upon the number of rows returned by
the query .Is there any way to find the row index of the datatable and
to increment that no to keep the next records orelse tell me some
other way to keep all the records retrieved through looping the
query in the same datatable or in the same DataSet.
Kindly expecting the reply,

Problem saving 24 hour date/time in SQL
I have an SQL table(MS SQL 2005) with a field called SignInDate and
have created this as DateTime. When I save the current time using the
Now function, it does not save the value in 24 hour format.
For example, if it is 2:15:36 PM (i.e. 14:15:36) it saves the value in
SQL Sever as 2007-03-08 02:15:36.000 and when I read it back, it
resuls in 2:15:36 AM.
I have tried formatting as a string using HH:mm:ss for the time
portion but SQL Server still saves as shown above. How can I get it to
save as 2007-03-08 14:15:36.000 so it will be correct when I read it
back?
TIA,

SQLBulkCopy and SQL Server 2000?

Using Sql2005's OUTPUT
Hello all...
Here is what i want to do (in VB code)...
<code>
Dim SQL As String = "SELECT ROWID FROM (INSERT INTO STATIC_CONTENT (NAME,
CONTENT) OUTPUT INSERTED.ROWID SELECT 'Contact Us', '') SRC"
Dim newId As Integer myDbObject.ExecuteScalar(SQL)
</code>
Assume that myDbObject has already been set up with all the necessary
connection strings and junk.
The question revolves around using ExecuteScalar to return the value from an
INSERT-OUTPUT clause.
I can 100% guarantee that this is a single-row insert everytime.
This table (STATIC_CONTENT) has a trigger on it to set the update-date every
time it's updated.
Is this possible somehow? short of writing my own overloaded ExecuteScalar
that would turn this into a whole big T-SQL BEGIN/END block with temporary
variables and all that mess?
Thanks in advance,

Dynamic access to DataTable during DataAdapter.Fill
Hello,
Does anyone know if its possible to access the row/column values of a
DataTable while a DataAdapter is filling the table? Maybe using a new thread?
I am currently trying to use a seperate thread for access while the main
thread runs the DataAdapter.Fill and so so far it looks like the table and
rows/columns are not added incrementally, but instead are only filled once
entire resultset has been determined and returned.
Any advice is appreciated.

can I alias an ADO.Net table (tablename)?

Is it possible to alias an ADO.Net table? I have this one table that has a
pretty long name dsDataEntry.Tblsomebigtablename.
I tried Dim dt As DataTable = ds...Tbl...
Welll, that created table dt, but it did not populate the table. I guess I
would have to loop through the original table.
So is there a way to assign a shorter name to the table I need to work with?

Parameterized query problem using Access Database in VS.NET2005
New to the VS.NET 2005 and I am writing a program using an access database as
the datasource in visual studio.NET 2005 The problem I have is I am trying
to write a parameterized query where a wildcard can be used to pull a
complete name from only one or two characters entered. If I have the exact
name I can get it to work with a ? but this defeats the purpose of the query
and the sql select for the access database doesn't reconize the * that is
used in access as a wildcard.
The satements I have right now are:
SELECT CustomerNumber, Name, Address, City, State, Zip, Phone, LastOrdDate,
Inactive
FROM Customers
WHERE Name = ?
SELECT CustomerNumber, Name, Address, City, State, Zip, Phone, LastOrdDate,
Inactive
FROM Customers
WHERE CustomerNumber = ?
and when I try to do this (or any version of it):
SELECT CustomerNumber, Name, Address, City, State, Zip, Phone, LastOrdDate,
Inactive
FROM Customers
WHERE CustomerNumber = '*'
or
WHERE CustomerNumber = ? &'*'
I get an error of this:
Error in WHERE clause near '*'.

Stored procedure returns two result sets
Hi everyone,
I have a stored procedure called 'PagingTable' that I use for performing
searches and returning just the results for the current 'page'. That way I
can do my paging on the server and only the data that actually gets
displayed on the webpage is returned from the database server.
The sp returns two result sets. The first result set contains a single row
and columns telling me how many total results the query retuned, how many
'pages' (based on the number of items per page that I specify) and the
current page I am on. The second result set returns the rows of data for
the current page. In 'classic' ASP I handled it this way:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
Its that last line that was key. I could then go on loop over the results
and output them. How do I do this in ASP.NET 2.0? The DataSource control
only allows a single "DefaultView". So does the DataReader. How can I bind
a repeater control to the second result set (the actual data) and use the
info in the first result set to build a "pager" UI?

Filling tableadapaters in master/child dataset
I have defined a strongly-typed dataset with two tableadapters in a
master/child relationship. On the master tableadapter, there is a parameter
which restricts the fill of the tableadapter to less than the entire contents
of master table.
After filling the master table, do I simply fill the child tableadapter with a
single call and it magically "knows" to fill the child based on the
relationship, or do I have to walk the master table rows and fill the child
multiple times based on the rows of the master?

DataAdapter.Fill, ConstraintException, and Primary Keys
I am running into ConstraintExceptions with the following VB.NET code:
Dim daResult As SqlDataAdapter = New SqlDataAdapter
Dim Result As DataSet = Nothing
[code to set up the data adapter with a stored procedure,
parameters, connection, etc.]
daResult.MissingSchemaAction = MissingSchemaAction.AddWithKey
daResult.Fill(Result, tableName)
and SQL code in the called stored procedure:
SELECT '2_FieldID' = table2.idfield
FROM base_table
LEFT JOIN
(table1 INNER JOIN table2 ON table1.2_idfield =
table2.idfield)
ON base_table.idfield = table1.base_idfield
where idfield is an IDENTITY(1, 1) PRIMARY KEY field on table2 and
2_idfield is a foreign key to it on table1.
*However*, I don't get the ConstraintException when I make the SQL
statement like this:
SELECT '2_FieldID' = table1.2_idfield
FROM base_table
LEFT JOIN
table1
ON base_table.idfield = table1.base_idfield
nor do I get this error when I leave out the VB.NET line:
daResult.MissingSchemaAction = MissingSchemaAction.AddWithKey
I do need the MissingSchemaAction; I can fudge my stored procedures
to avoid selecting the idfields directly, but I can't help but feel
that I'm missing something here, especially since I'm using the same
code in a lot of places and only running into the problem in a small
handful of stored procedures which aren't, as far as I can tell, bases
on tables with any different constraints than the unproblematic ones.
(Is there something I should be looking for?)

Strange Dataset update problem passing to Webservice
I've encountered a strange problem when trying to update data in two
tables using a dataset. My application is split between a client
(presentation) and webservice (business and DAL).
I have a typed dataset, HSEDataset, containing two tables related by a
foreign key constraint. I use the standard GetChanges() method to get
a dataset containing only the changes to the tables, looking at these
tables I can see my changes on the client, i.e. 1 row in table 1 and 1
row in table 2, so far so good.
When I send the dataset to my webservice, however, I get 1 row in
table 1 and 0 rows in table 2?? The first table is subsequently
updated without a problem, the second obviously updates nothing. I've
since simplified things even further by just sending the second table,
however, using GetChanges on the dataset and sending the subsequent
table still doesn't work:
Dim pChanges As DataSet = Me.HSEDataset.GetChanges
Dim mychanges As HSECoreBLL.HSEDataset.IncidentsDataTable =
pChanges.Tables(1)
But calling GetChanges directly does:
Dim mychanges2 As HSECoreBLL.HSEDataset.IncidentsDataTable =
Me.HSEDataset.Tables(1).GetChanges
Both methods show 1 row in the resultant table after calling
GetChanges on the client, but only with the second method does the
webservice receive this row!! Something must be happening when the
data is being marshalled and sent to the webservice, but I can't find
the problem replicated anywhere else, any ideas? Tag: Microsoft Training/ Certification Dumps /Materials Urls Tag: 137978

SqlParameter slower in combination with DataAdabter.Fill method???
Hi there
I found a starnage behavior. I have a method 'GetDataFromDB', which i use
internaly in my class to get data from the db. Now if i build the query
using SqlParameters for the date my query takes up to 60 sec vs. 2 sec if I
do not work with the SqlParameters!
What can be the problem? Did anyone of you had the same problems?
SQL-Statement with DateTime-params:
SELECT @TitleID AS TitleID, StationID, COUNT(*) AS BroadcastCount
FROM tPrg WHERE TitleID = @TitleID
AND StartTime >= @DateFrom
AND StartTime < @DateUntil
GROUP BY StationID ORDER BY StationID
SQL-Statement without DateTime-params:
SELECT @TitleID AS TitleID, StationID, COUNT(*) AS BroadcastCount
FROM tPrg WHERE TitleID = @TitleID
AND StartTime >= CONVERT(DATETIME, '2007-01-1 03:00:00', 102)
AND StartTime < CONVERT(DATETIME, '2007-02-28 03:00:00', 102)
GROUP BY StationID ORDER BY StationID
The implementation of the mentioned method:
public DataTable GetDataFromDB(string sqlStatement, string tableName)
{
DataSet ds = new DataSet();
ValidateConnection();
_dbCommand.CommandType = CommandType.Text;
_dbCommand.CommandText = sqlStatement;
DbDataAdapter adap = _provider.CreateDataAdapter();
adap.SelectCommand = _dbCommand;
adap.Fill(ds);
ds.Tables[0].TableName = tableName;
return ds.Tables[0];
}
Any ideas? Thank you very much for your help!

Does DataSet.Copy() remove event handlers?
I'm wireing some event handlers to tables in a DataSet. This is performed in
EndInit(). Everything works well untill I use the Copy() method of the
DataSet class. I see that the EndInit is run for the copy, so that the event
handlers are correctly added. But at some time the connection between the
tables and the event handlers is lost. I suspect that Copy() does something
after calling EndInit.
Does anybody now why this happens and how I can avoid it? Maybe EndInit is
not a good place for wireing up events? Tag: Microsoft Training/ Certification Dumps /Materials Urls Tag: 137975
Closing Jet Database seems unreliable
I am having difficulty getting Jet databases to close by calling the
DbConnection.Dispose method. The method seems to work, and the
connection state changes to closed, but about 25% of the time at some
level the process is keeping hold of the connection, and not deleting
the ldb file for example. Then when I terminate my process the ldb file
gets deleted... Or sometimes if I open and close a whole series of mdb's
in sequence the ldb's will build up and up then suddenly they'll all get
deleted at once... :-\
If I open my databases exclusively (mode-share exclusive) (for safety as
the app is single user) then if I close one and then reopen it in the
same process I'll often get a message that the database is already
exclusively open.
Suspecting that connection pooling was getting in the way I tried adding
"OLE DB Services= -1" or -4 to the connection string and curiously this
seems to make things worse. It virtually guarantees that the file will
remain open whereas with pooling turned on the closure seems to work
about 75% of the time. In tests I can see no difference from my point of
view between the times when the call works and the times when the call
fails.
Does anyone know a guaranteed way in ADO.NET of killing a connection to Jet?
I want to do this so that my app can (for example) backup or restore the
Jet database from a menu prompt while the app is still running.
Is there any way of spying what is happening at the underlying Jet level?

import large text file
hi there,
i have a huge large text file (350.000 lines) that i want to import to
a MS Acccess Database, of course i don't want to use Access, but do it
with C#.
i already have tried the AddRow method or Insert, reading each line of
the text file, the problem of course is velocity, it would take more
than 4 hours to add all lines/records to the database.
any suggestion?

Select query question
Hi
I am using below query to retrieve records from backend sql server 2005 db;
SELECT ID, Company ....
FROM tblClients
WHERE (Status = @status)
Problem is that sometimes I need all records regardless of what is status.
How can I achieve that? Can I add something like OR (Status ="") OR (Status
isNull) in the WHERE clause? If so, would using OR make the retrieval slow?
Thanks

Update and delete sql not generated by wizard
Hi
In my vb winform data app with sql server 2005 backend, when in dataset I

Error using money datatype parameter and DBNull.
Hi,
Hi,
I am getting an error executing a SQL Server stored procedure with parameters of type
money. The following code fails:
With cmd
...
If mActualCost = Decimal.MinValue Then
.Parameters.AddWithValue(PRM_ActualCost, System.DBNull.Value)
Else
.Parameters.AddWithValue(PRM_ActualCost, mActualCost)
End If
...
.ExecuteNonQuery
End With
mActualcost is defined as type decimal. PRM_ActualCost is a string constant defining
the parameter name. By convention I define a decimal value type member variable to
have the value decimal.MinValue when it's value is unknown and therefore to be stored
as null in the database table being updated.
The stored procedure being executed is doing a simple INSERT into a table (there are
other parameters but they are irrelevant to this discussion). The ActualCost column
in the table is defined as a nullable column of type money. The parameter to the
stored procedure is defined as type money.
When my mActualCost variable has a value other than Decimal.MinValue, this code
succeeds and the database table is correctly updated. However, if it has the value
Decimal.MinValue, the code above fails. An error exception is thrown on the
ExecuteNonQuery. The error is:
"Implicit conversion from datatype nvarchar to money is not allowed. Use the CONVERT
function to run this query."
If I change this code to explicitly define the parameter's datatype as:
If mActualCost = Decimal.MinValue Then
With .Parameters.Add(PRM_ActualCost, SqlDbType.Money)
.Value = System.DBNull.Value
End With
Else
.Parameters.AddWithValue(PRM_ActualCost, mActualCost)
End If
then this code succeeds when the variable value is decimal.minvalue.
I have not done exhaustive tests for all possible datatypes, but I know similar code
succeeds with datatypes such as integer and string.
What's going on here with the money datatype and DBNull?

GetOrdinal problem
Hi,
Sorry for the cross post first of all. I posted to the ADO forum the
first time by accident.
I wrote a windows service in c# .net 2.0. There is a timer that fires
every second or so and when it does I start two threads (unless they are
still running from the last time).
One of the threads queries SQL server using a data reader. Every once
in a while I get a runtime related to GetOrdinal. Here is the call
stack:
at System.Data.ProviderBase.FieldNameLookup.GetOrdinal(String
fieldName)
at System.Data.SqlClient.SqlDataReader.GetOrdinal(String name)
at GTS.ComAppLibrary.LXRecord.ReadRecords(SqlDataReader _dr)
I googled for this and I did find one posting on MSDN that goes back to
Nov of 2005. A number of people have had a similar problem, but nobody
seems to have a good solution.
Unfortunately I have just used a work around of supplying integers to
the GetString (and other get methods).
Is there a fix for this problem? Has MS been able to reproduce the
problem?
Thanks

Weird problem inserting image in DB...
Hi all,
I'm experiencing quite a weird problem inserting an image in a database.
I've designed a small form with some fields and a picturebox. I can fill all
of them and clcik the 'create item' button, and the task is performed
wonderfully, but as soon as I try to insert the data with the image set, it
simply won't insert it.
Debuggin the application I see that the data row is allways OK (even the
image) just prior to the TableAdapter.Update(), but the update method
returns 0 and HasErros equals false.
Up until this point, I would call the problem to be a bitch, but not wird
xD The 'weirdness' comes here:
I've attached a SQL Profiler to the user instance and found that the
following entries happen JUST when I try to insert the item with the image
field binded (and not when there is no image field set)...

Using TransactionScope and connection pool
hi,
I am trying to use TransactionScope and multiple async calls but get
Transaction aborted - transaction in doubt errors.
My program goes like this
using (TransactionScope ts = new TransactionScope())
{
do an insert on Table1 (Connection1 = new SqlConnection)
foreach table to read from aList
{
doSyncRead using Connection1
}
foreach table to insert from bList
{
do AsyncInsert passing in
DependentTransaction(BlockCommitUntilComplete) using new
SqlConnection(same connection string as Connection1)
}
Wait for all Inserts to Complete (using WaitHandle.WaitAll)
do a couple more inserts using Connection1
ts.Complete()
}
Each AsyncInsert create their own TransactionScopes using the
dependent transaction and call complete when finished.
Using Profiler I can see it gets to the TM Commit and seems to bail
out at this stage. But if I change the AsyncInserts to Synchronous
Inserts it works fine. All the inserts seem to complete - it is only
at the Commit stage that it fails with TransactionInDoubt.
The TransactionScope is in a web service. The error gets returned to
the client but then there still seems to be a TM REQUEST Command on
the SQL Server which then blocks other database requests until I
restart the DTC.
Can anyone tell me what I'm doing wrong? Is there another service I
need to enable or something?
thanks
Phil
BTW I also get a Promote Tran on Connection1 (seen via Profiler) -
starts and completes. Tag: Microsoft Training/ Certification Dumps /Materials Urls Tag: 137909
Reload dataset in DataError event handler
Hi,
I have a bound DataGridView, and I handle the DataError event like
this:
ShowMessageBox();
mhdsHospitalDataSet.MhdsHospital.RejectChanges();
mhdsHospitalTableAdapter.Fill(mhdsHospitalDataSet.MhdsHospital);
In other words: I show a message box, then I reject the changes made
on the DataSet, and then i refill the dataset.
I tested this deleting a record so it would throw an exception about a
foreign key, and it does. But the datagridview doesn't work in the way
i would like it.. I supposed that the DataGridView would show me all
my records again, but it shows me the records, without the record i
TRIED to delete (but failed to delete)!
What am I doing wrong?

Typed Dataset. Filtering/Selecting
Hi all
I'm in the process of making a system to integrate a webshop with an erp
system. All exports from the erp are XML based, and when I needed a test
application the obvious choice for me was to use XSD generated from the XML
export files, and from the XSD to generat Typed Datasets.
This works just great, and gives me a world of possibilities for
manipulating the data and binding it to different controls.
Or so I thought, cause I feel that I miss some key concepts about filtering
the Typed Datasets. In the bottom of this post you can se a simplified XSD
for my Typed Dataset
The DataSet contains a "Products" table that has a child "Product" table
The "Product" table has zero to any "LinkedLevel" related through a
"LinkedLevels" table
On the other side "Product" is related to a "Common" table through the
"Properties" table.
"Products"
|
"Common" ------> "Properties" ----> "Product" <----- "LinkedLevels" <-----
"LinkedLevel"
Now I make a databinding of a grid to the "Common" table, and this shows me
the "Common" properties of all the products just as I want:
this.dgvItems.DataSource = Dataset.Common
BUT
Now I want to filter this view, so I only show the "Properties" -->
"Common", for the "Products" that has a related "LinkedLevel" with Id=1000
How do I do this. Have been searching franticly but with no usefull results.
Any hint will be much appreciated.
Thanks in advance

I have an access database dataset which a draggedonto a form which also put
the data navigator on the form. The problem is that when I ADD a new record
witht he add button, it gives me a primarykey that has already been used and
deleted before in the database. Then of course when you try to save it you
get an error because access won't allow this.
I do not undertand why this primarykey issue is happening? If I create a

Master/Child Binding not working
I have created a dataset containing master/detail tables and used it as
a datasource for a master BindingSource. I created another BindingSource
for the detail table - its datasource is the master BindingSource and
its DataMember is the relationship between the 2 tables.
I laid out 2 DataGridViews. The first grid is bound to the master
bindingsource and the second is bound the the detail bindingsource.
Navigation works just fine. When clicking on the parent rows, the
associated child rows appear in the child grid.
Now I want to break out the columns in the detail rows into individual
controls - textboxes and comboboxes. I set the databindings of the
individual controls to the detail bindingsource and its associated
datamember. When I click on the child rows of the child grid, nothing
appears in the individual controls.
What am I missing here? I've struggled with this problem for quite a
while.
