Access :: Using A Subquery Value As Default In QueryStringParameter?
Jun 29, 2010
Using this call;
<asp:AccessDataSource id="AccessDataSource2" runat="server" DataFile="_database/92592_Web.mdb" SelectCommand="SELECT *, (SELECT MAX(ID) as Max_ID
FROM myMovies) FROM [myMovies] WHERE ([ID] = ?)">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="1" Name="ID" QueryStringField="ID" Type="Int32" />
</SelectParameters>
</asp:AccessDataSource>
How can I use "Max_ID" as my DefaultValue? So that basically if the page gets passed without a parameter, the SQL will use the Max(ID) as a default. Can I use Max_ID as a DefaultValue?
I'm an old .asp developer still on the learning curve of .NET so some of this stuff is a little daunting. In .asp doing something like this was pretty easy...
im doing an update in web page by pressing a button. At the start some of the update was from a trigger, but i decided to put the hole update statement in the web page as an updatecommand in VB. this is the error Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.The statement has been terminated.and this is the code.
[Code]....
the error is in the updatecommand. And i dont know what is it.
I am trying to secure very mixed content that is located in an ASP.NET directory. For purposes of this question, it can be ~/MyApp/.
I want all of the content in the directory and its subdirectories restricted to authenticated users. The default.aspx page, though, should be accessible to everyone. This is the web.config in that directory:
[Code]....
Now if you are an unauthenticated user, everything works fine if you request [code]....
The problem occurs in that visitors do not always request "Default.aspx". We have a default document configured so that they get Default.aspx even if they just request "/MyApp". An authenticated user works fine, but an unauthenticated user is directed to the login page.
Now I know that essentially this happens because even though the request for "/MyApp/" will actually end up serving up "/MyApp/Default.aspx", the security system is only checking for "/MyApp/" since that is what I requested. That is then getting the default security for the directory.
How can you configure an exception to allow access when no particular file is requested in the directory??
Is there some dependency between DefaultDocumentModule and UrlAuthorizationModule? In this environment, the UrlAuthorizationModule has been removed and re-added in order to make sure it fires for non-managed requests. I would not expect that to change the order of execution, though, since UrlAuthorizationModule usually goes after DefaultDocument.
A workaround could be to set up the opposite security with the directory being open, and then trying to secure individual files. Because of the (changing) number of files, and extensions, etc, and the fact that you cannot use wildcards in a <location>, this is not really a workable solution for me.
Let's say the current webpage name is ABC.aspx and I want to make two different webpages based on this page; ABC.aspx?Mode="A" and ABC.aspx?Mode="B" (By using querystringparameter). When the user opens ABC.aspx?Mode="A" page, I want to show below gridview but when the user opens ABC.aspx?Mode="B" page, I want to show below gridview except "Gender" column.
My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.
Im just wondering if the default access rights of IIS in the PC where it is running is administrator? and by default does IIS has access to computer resources e.g. Printer, Finger Print Scanner, Smartcard reader installed in the same computer where the IIS is running.
In my default.aspx there's a label, then I am using an iframe which src="page1.aspx". When I click on the page1.aspx, I want the label text to change according to some click events on the page1.

I always received an error of: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I have some ajax fucntions on my default.aspx that I use for saving data to my db. I have the form on my web control. When I try calling the function from my button which resides on the web control. I get an error.
I need to call that function from my registerform.ascx. How do I do that from within the registerform code behind?
* 100 AS PERCENTAGE FROM support.SRFILE INNER JOIN BSFLBWF AS BSFLBWF_1 ON BSFLBWF_1.Incidentx = SRFILE.SRONUMBER WHERE (BSFLBWF_1.Closex IS NULL) AND (BSFLBWF_1.DedTypex = 'School' OR BSFLBWF_1.DedTypex = 'LAN-MLE') UNION ALL
The rest of the query continues as the above albeit selecting the same data from different tables and works fine.
The issue I have is that I want to Select some more data (another SELECT query) but with a different Where clause e.g. WHERE (BSFLBWF_1.KPIx NOT LIKE 'KPI%' OR BSFLBWF_1.KPIx NOT LIKE 'Proactive%') AND (BSFLBWF_1.Availabilityx LIKE '')
The problem is that this WHERE clause returns data which the above in bold has null values for (and thus doesnt work). Im still selecting the same data its just the WHERE Clause has changed. Is it possible to run such a query? If so, can it be done via a sub query?
I need to write a query (SQL Server) which gives me data according to the tags say if I want bookIds where tagid =9 it should return bookid 113421 and 113422 as it exists in both the books, but If I ask data for tags 9 and 10 it should return only book 113421 as that is the only book where both the tags are present.

im working on visual Studio 2010, and i have an error on an update.
this is the code in VB.
[Code]....
Thats the code and the error is:
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.`
While developing and ASP.NET application in C# or VB using Visual Studio 2005/2008/2010 (Not a problem in 2003), if I create a new method automatically by double-clicking on a control in the designer or picking the new method in the code editor dropdowns (VB only), the access modifier is always protected instead of private. This is annoying because my developers have to manually change the method to private every time.
Public Function ProductList() As System.Linq.IQueryable(Of Northwind.Products)
