DB/Reporting :: Command Builder Isn't Recognized
Apr 10, 2010
i'm using this code to try and write a value to a table in an access database. when i try to write oledb.oledbcommandbuilder, intellisense doesn't recognize this but it doesn't throw an error up for that line either. when i try to execute this code i get the error "syntax error in UPDATE statement"
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUPdate.Click
Dim myConnection As OleDb.OleDbConnection
Dim ds As New DataSet

I will have to perform updates/inserts/... on several relational tables of an Access database but I know that the Command builder usage is limited only to one table at a time.

I'm experimenting with the sql command builder and it seems to do nothing when trying to update existing rows. If I create a new row and then add it then it works fine but I cant seem to update an existing record.
Heres what I have at the moment
Code:
Dim strConnection As String = "Server=myServerSQLExpress;AttachDbFilename=C:databasepath estdb.mdf;" & _
"Database=testdb; Trusted_Connection=False;User Id=sa;Password=test;"
[CODE]...
But I'd really like to find out why its not working when using the command builder. I'm working with VB.net 2010 express and SQL server express.

I'm using a datagridview to display data and make updates to my access database. I was able to display data from my database to the datagridview but it is not filtered. The datagridview displays all the records on my database. I tried using query builder to execute sql select statements that will filter the data and this is where I'm stuck. Im using a variable as a parameter to the sql statement and I dont know what syntax to use in Query Builder. I tried to use @varname, '" & varname & "', and

I need to filter a measurements table that consists of 63 measurement objects that may or may not be tested more then once. The entries are put in a Batch table on a SQL server in the following fashion:
ID: | Serie | Test object | Min Amps | Max Amps | OK?
DateTime| String | Integer | Double | Double | Boolean
So there may be multiple entries in my database with the same series and testobject number but with (slightly) different results.
Currently I just select: SELECT * FROM Measurements WHERE Serie = 'XXXX' and use a datareader object to fill a datatable and then I let loose a routine on it that will either: Get the last result that produced a good measurement, so OK = 1 and max ID. Or the last result that produced a bad measurement if there are no good ones. I then end up with a list of 63 either good or bad measurement objects with the last good result, and if there isn't one then the last bad result.
Now I know that SQL is quite powerfull and I suppose that it must be possible to directly query for these results without a programatical routine re-filtering the results. I suppose it's like Selecting within a select statement..

Currently working on a web-service with Oracle10g as back-end. Here is my problem.
1. The table I need to populate has 100 columns. I have no control over the design of the table.
2. I wanted to use the "deriveparameters" method of OracleCommandBuilder, but found out that this is "costly" in terms of performance. What I initially planned to do was to derive the parameters from an open connection, close the connection, then maybe cache the parameters obtained but I don't know if this is possible.
I am unsure how big of a hit the performance will get if I continue using the "deriveparameters" method WITHOUT caching the parameters driven. The environment is as follows
-intranet
-around 2000 users
-users spread out in different parts of the country
I am not familiar where they will put the web pages of the application, the web service and the database. I don't know if they'll be putting it in different servers or on one server, but that's something we cannot control too, that's why I am looking for the best approach.
I just don't want to hard-code all that parameters and if, for instance, we need to change some properties/parameters, it will be a pain to maintain the code. It would be nice if someone here can point a way to automate the whole thing w/o the performance of the system taking a hit.

I created a report viewer app that takes a command line parameter, the report filename, and opens the report. I also created a ODBC File DSN that I want to redistribute. However, currently, the DSN needs to reside in 'c:program filescommon filesodbcdata sources'. Is there a way for the report to look for the DSN in the application directory? Also, what components besides .NET 3.5 are required to redistribute the report and report viewer app?

First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.

I haven't touched a project in about 8 months. It's ongoing for work, but hasn't really been published fully so it gets worked on in my spare time. I went to recompile and the build failed. It had previously worked. I can't figure out why. Part seems to be due to AxOWC11 being recognized, but it shows up in the namespaces. I'm looking for the .dll that shows up as AxOWC11.dll, but I'm not seeing any. I do have one that shows up as AxInterop.OWC11.dll and I do have just a OWC11.dll in my list. I've posted some of the errors below.

i know someone will say this belongs in database programming but i don't think this problem is to do with databases and is more to do with visual studio.
when i start to type oledb.oledb..... intellisense would usually give me an option for oledbcommandbuilder. in the current program i am doing for coursework this option is not given. i can choose oledb.oledbcommand but i do not know how to use it (too advanced for A-levels, yes i'm british) if i actually type oledb.oledbcommandbuilder visual studio does'nt show an error in my error list. so what is going on? how can i get visual studio to recognise oledb.oledbcommandbuilder?

I would like to start a data base. Im using vb2005. I've started a new windows application. I have added a new data source to the project. Then I added a new TableAdapter in the dataSet.xsd part of the project. When I'm completeting the wizard, when I click on the QueryBuilder, when the add table window opens, the table already in the program ( that comes along with the TableAdapter ) isn't recognized. I've clicked on the refresh button but it still isn't recognized. (example: DataTable1 isn't recognized in the add table form in the query biulder of DataTable1TableAdapter)

I'm trying to use MailDefinition in my vb.Net application, but the class is not being found.
Actions:Imports System.Net.Mail ' I use this statement
My intelliSense typing does not show MailDefinition. I get as far as Sytem.Net.Mail - but MailDefinition is not an option.I tried added a reference to System.Net (not necessary, but trying different things), still it doesn't recognize the class.
Question:Do I need to register a DLL or something? How do I gain access to class MailDefinition in my Form class?
EDIT:BTW: In object browser MailDefinition is defined as:
System.Web.UI.WebControls.MailDefinition
I get an error saying that UI is not a member of Web Does this mean I need to add this control? it's not on my Toolbox. Should I look for and register an OCX file?

I have a small app with one form (form1) which is supposed to be hidden until a hot key combo is pressed. I have read and taken sample code from: [URL]. I do have a keyboard class that hooks keyboard input, (I have my reasons) but it's odd that it will recognise the first hotkey and fire the event, but none after that? The problem is, I can make the form show, but not hide again. It will only recognise one shortcut, one time. How do I make it respond to another hotkey combo? Is the handle changing? Even with focus, the enabled form is not hiding again.

I am trying to parse a date to a datetime picker but this error keeps on appearing "String was not recognized as a valid DateTime" The reason behind this is because the date format of the computer is "MM/dd/yyyy" whereas the date am passing is in this format "dd/MM/yyyy" Here is how I tried resolving the problem:
DTDateReceived.Value = Date.Parse(ListView1.Items.Item(ListView1.FocusedItem.Index).SubItems(7).Text)
The aforementioned error occurs

working with dates is driving me mad I have the following function to parse al datetime strings in my project:
Public Shared Function ToDate(ByVal obj As Object) As DateTime?
If obj = String.Empty OrElse obj Is DBNull.Value Then Return Nothing
Return DateTime.Parse(obj.ToString)
End Function
Most of my date strings on my pc are "yyyy/MM/dd" and it parses fine. However on the server the dates are "dd/MM/yyyy".I tried this but it made no difference:
Public Shared Function ToDate(ByVal obj As Object) As DateTime?
If obj = String.Empty OrElse obj Is DBNull.Value Then Return Nothing
Return DateTime.Parse(obj.ToString, System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat)
End Function
on my pc if I assign DateTime.Now to a textbox I get 2011/05/31 08:02:00 AM for example. On the server I have my project the date displays as 31/05/2011 08:02:00 AM. Now I use objectdatasources to save the values to my database. Yesterday I was getting this error:Cannot convert value of parameter '' from 'System.String' to 'System.DateTime'until I formatted the date value like so:
Me.odsRates.InsertParameters.Add("CreatedDate", rt.CreatedDate.ToString("yyyy/MM/dd hh:mm:ss"))
