visual studio .net debugging: I set set breakpoints in the code that is generated for a TableAdapter in VS
Beta 2, but the debuger never stops at them. I locate the generated source
files by browsing into the dataset through the Class View. Is there a
better way? What might be going wrong? Thanks!

Hi Tom,

[quoted text, click to view]


If I set a breakpoint in my custom TableAdapter's constructor function, the
program will stop at that point as expected.

So which line of the generated code of your TableAdapter do you set the
breakpoint at, would you please illustrate the detailed repro steps for us,
we need to repro the problem in our local environment for test...


Thanks!

Best regards,

Hi Gary,

Thank you for the reply.

Here are the steps to reproduce the problem using the Northwind database.

Create a connection to Northwind database
Add a Dataset named TestDataSet to project. The DataSet Wizard runs
select Northwind connection
use SQL statements commands
use Query Builder to select Category table columns CategoryID,
CategoryName, Description
Select options to generate Fill, GetData and Update methods
Wizard creates DataTable named Categories and TableAdapter named
CategoriesTableAdapter
Save TestDataSet. This generates adapter code.

In the ClassView browser navigate to TestDataSetTableAdapters |
CategoriesTableAdapter
Double-click on method GetData, set a breakpoint at the method entry point
and at the code line for Me.Adapter.Fill(dataTable)
Select the New method of CategoriesTableAdapter and set a breakpoint at
MyBase.New

On design surface double-click on ObjectDataSource1 to create method
ObjectDataSource1_Selecting
Add code "Dim i As Integer = 1"
Set a breakpoint at this line.

Add a blank WebForm named Test.aspx to the project
In design mode for Test.Aspx drag an ObjectDataSource from the toolbox to
the surface -- the instance is named ObjectDataSource1
Right click on ObjectDataSource1 and select Configure Data Source
Choose business object TestDataSetTableAdapters.CategoriesTableAdapter
Choose method GetData and Finish the wizard.

Drag a GridView to the design surface of Test.aspx
Set the DataSource to ObjectDataSource1
Save the page

Compile the solution
Press F5 to run app in debugger
The debugger displays test.aspx.vb and stops at line "Dim i As Integer = 1".
Press F5 to continue.
The page appears with data -- pretty cool, actually, but...

NOTE that the debugger does not stop at the New, GetData, or Fill methods in
the CategoriesTableAdapter.
When I browse to the source for CategoriesTableAdapter via the Class View
the breakpoint dots are open circles, not solid, and hovering over them gives
the message "At testdataset.xsd.72cecc2a.vb line 515... The breakpoint will
not currently be hit. The specified module has not been loaded."

In my test the source file containing CategoriesTableAdapter is named
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\Temporary ASP.NET
Files\qtrax_proto_1\f54d4011\21c74200\Sources_App_Code\testdataset.xsd.72cecc2a.vb

So, how do I find the source file that *is* loaded?

Thanks much for your help.

Hi Tom,

I think the difference you met between the winform and webform application
is a normal behavior due to the differernt compilation model for ASP.NET
2.0. In asp.net 2.0, the component code are put in App_Code folder which is
dynamically compiled. That means the dataset's code you view in IDE is just
partial class's portion , not complete. The complete code (or refer as the
final code source for the actual executing DataSet instance) are dynamic
generated from this and is put under the ASP.NET temporary folder. That's
why the source in your IDE's project won't take effect when you debugging
the APP.

Thanks,

Thank you vrey much for your reply, Steven. Does this mean that we can't
debug Web applications? There is an awful lot of functionality in the
TableAdapter code and it is very unfortunate not to be able to see what's
going on.

Perhaps there a set of steps where I can attach the debugger to the asp.net
worker process and find where the consolidated source file is?

Thanks again,

Thanks for your followup.

I think such problem won't occur for normal component classes we put in
App_Code that'll be compiled. For example, we define a normal helper class
and put the code file in App_Code, I think the source can be debug into
correctly. The problem is somewhat due to the particular compile model for
the dataset. In addition, since the orginal bin dir still avaialbe for put
existing precompiled component, we can put Typed DataSEt components in a
separate class library project and put the compiled assembly in "bin" dir,
I think this can help us use the model that normal .ne app use rather than
let the asp.net runtime dynamic compile it.

Thanks,

Steven,

That worked for me -- thanks for the suggestion.

I created a separate project for my Data Access Layer and created my
DataSets there. I compiled this project and added a reference to it from the
the Business Logic project. Now the debugger stops at breakpoints set in the
TableAdapter code.

Thanks again,

Great Tom, we are delight to our suggestion works for you:)

Good Luck!
