I am trying to access the TableAdapter object from my WebPage Class on the Page_Load event , so I can modify the Command.CommandTimeout. Unfortunately, I cannot find a way to have access to the TableAdater object.
I created a new DataSet object using the wizard and had no probs, it's very straightforward. I created a GetProducts() method and also added a GetProductCount() method. I read somewhere that when the DataSet is saved, it will generate the TableAdapter classes and store them in the project nested under the DataSet object. This isn't happening, the files aren't there and yes I'm displaying all files. There *is* however the TableAdapter class but it's in not in the project, it's a temporary file w/ the following path:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Fileswebsitef38f8b5500014aeSources_App_Codepw_products.xsd.72cecc2a.cs.
I saved the DataSet several times, compiled the entire solution and even closed the solution yet this temporary file isn't getting saved where it should be. Does anyone have any ideas abt this? I'm eager to start developing my DAL and def want to use these TableAdapter classes.
Just wondering if there are any online recources on writing SQL in a website? i have a database linked to an sql server, and from access etc. i can access it no problems.. just wanting to access it from a website.
I have a VB-class object running inside MS Transaction server. A function inside this class makes use of a temp table when a user does a web-query on my server which gets some data from SQL 6.5. Problem is, although the temptable is destroyed at the end of the function, my TempDB in SQL gets gradually fuller with each query that runs.
Why does this happen. I cannot release any of the tempdb space already in use, so eventually the tempdb gets completely full and SQL stops running.
I have created a report in reporting service 2005 and i have succesfully integrated the report in asp.net webpage. But i want to know whether it is possible to access the methods and properties of (report)rdl file in the asp.net webpage. If it is possible then please tell me how to implement it
Now I need to store the oMyClass object in the database for later use, at which point I would get it out of the database, cast it back to myClass, and be able to acess its properties, etc. My problem is that the classes that I am working with are not serializable, so I cannot store the objects as XML. Does anyone have an example of doing this programmatically with C# and ADO.NET. I am assuming that I would have to store it in a vabinary column, but how do I get it in there. Any help would be greatly appreciated. Thanks.
I copied my .mdf database from a file and pasted it into the visual studio project App_Data folder.I can see the tables and the columns etc when creating my TableAdapter, and create my sql query etc, but then when I hit the finish button, I get this error "an Unexpected Error has OccuredError Message: Access Denied". Anyone know why I can't create my TableAdapter?

for some reasons, I have to get access to the TaskHost during validation and execution. For example, I wanna know, if my task is within a container or not (parent is Sequence).
For the UI during design time, there is the TaskHost parameter. What about the execution time or during validation?
I have been using the .NET Enterprise Library for DataAccess patterns for some time now. I'm going back to a bunch of old legacy ADO code written in VB6/VB5 and would like to try and create the same "centralized" class that all of my code can instantiate and call to open database objects, call stored procedures, etc.
Does anyone know of any samples of papers which might describe this?
I'm trying to use the Data Access Application block, and am having some issues with configuration. I am using it in a class library, and it seems that with v 3 you need to configure the DAAB first, making changes to the configuration file. However, in a class library, I do not seem to have the web.config or app.config file to change. So where do I need to store the configuration settings? Thanks, Paul

I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.
Hi, I need to audit any access to table (example table creditcards) profiler work fine if table creditcards referenced by select/ upadate/delete or procedure
but if I create view
create v_alex as select * from creditcards
profiler with all events would show only v_alex
Application modifing and number of views growing ...
Any way to trace accees to creditcards if it referenced by view ?
I would like to remove an index from my database, but I need to verifythat it is not being accessed before I do that.I tried running Profiler, but it doesn't seem to be giving me theinformation I need. I put in a filter for ObjectName, but it seems tobe ignoring it - i get several entries in the profile trace, but novalue in the ObjectName column.Is there an easy way to monitor for object access?Thanks so much!SQL Servef 2000 SP4(I also have 2005, SP2, if there's a better way to do this with 2005)
Hey there. I must write a stored procedure to update a table and want to make sure the ID used in both Acceptance and Production will have the necessary access. The ID will inherit it's access to the resource though a ROLE. Wondering if there are queries out there that can traverse for example, the roles/id's that have access to it... Thx!
Hi everyone. I am having difficulties with a cursor that I am trying to write. The purpose of the cursor is to loop through all tables in a selected Database and revoke "Select" access to that table for the indicated role (RoleToRevoke). I am getting the error on the @name variable within the REVOKE statement. I have placed a comment indicating where I am getting the error. Is there a way to have sql server interpret this @name variable within the REVOKE statement? Thanks for your help.

Aaaaaarrgghh ! (that's better)I am trying to convert a field within my Oracle 9i Database that is oftype BLOB (but this BLOB may contain a combination of clobs/varchars orimages such as gif images, jpg images) to Microsoft SQL Server 2000using Microsoft DTS.On trying to perform this simple conversion I recieved the error "Needto run the object to perform the operation - Exception AccessViolation" from Microsoft DTS and my table that contains this BLOBfield is not converted across.After further investigation I implemented the fixes suggested by theMicrosoft Knowledge Base and "sqldts.com" but still no joy the errorkept occuring.I discovered my modifying the step in the DTS package that handled thistable conversion that contained the BLOB column that when I changed thedata type on my SQL Server target table to VARBINARY and modified thequery so that only the BLOBs that contained clobs/varchars were broughtacross that the error went away.I then proceeded to create another DTS package step that had a querythat only brought across the BLOB column that contained images such asgif images/jpeg images etc. and the error went away and the target typefor the SQL Server target table was set to IMAGE.As the data for this BLOB contains a combination of VARCHARS/CLOBS(concatanted) and also GIF IMAGES/JPEGS in the same source column withOracle 9i I require the same in my target table within SQL server asone column (and I should be able to do that with type IMAGE especiallyas it can store larger objects than VARBINARY but any source BLOBS thatcontain VARCHAR/CLOBs don't seem to want to be loaded as IMAGE theywill only load in to VARBINARY).However judging by my experiences above this doesn't seem to bepossible ?Can anyone help me out with this ?I am on Microsoft SQL Server 2000 Service Pack 4 with latest MDAC(2.8.1).Cheers,Gary

Ok, just made a TableAdapter and the SELECT statement works fine and pulls data. But doing an INSERT is something different, it craps out wanting a login. No neat Wizard (or so I haven't found yet) that lets me give the TableAdapter the login info for the SQL Server, which I have. Do I need to write code with the login and password for the SQL connection instead? -Ed
Hi, I have a TableAdapter created in a Dataset. I'm creating a search function for a table, and here's how my code looks like in the "Add Query" wizard: Select * from Event where eventname like '%@EventName%' But when I click on preview data, I do not get the prompt to enter a value for the @EventName parameter, where went wrong?
