about some APIs I can get the hwnd of a foreign application. But is there a possibility to detect if this application has areas with scrollbars (for example internet explorer hast a menu, tabbar and an area with scrollbars)? If so, how can I get the rect of this area and how can I access this area (scrolling-event).

I'm trying to create a table which has one (or none) record per assignment.
The general problem is that I can't get the foreign key in one of my child tables to populate the primary key from the parent table. I have a parent table named "ISSUES" and a child table named "ISSDESC". The primary key for ISSUES is ISS_ID which is an autonumber. The foreign key is ISS_ID in the ISSDESC table which is just a number. I'm using MS Access and an OLEDBConnection as the method. I've created the relationship in MS Access and also created the datarelation in the VB.NET code.

View 2 RepliesI have a parent table called users which stores all the user info with a prime key field called ID. Now in the child table which has a seperate foreign key associated with the ID field in the parent table.
What I would like to do is be able to populate the foreign key once once the user uploads data into the child table with the user ID it has.
So far I have created the associated foreign key with ID field in the user table and also programmly through data-relation related the table but now sure on how to get the value from the relation.
The foreign key in the child table is called 'U_ID' as shown in the snipet velow.

I'm developing an app in VB.Net (Visual Studio Express 2008, on Windows Vista) that connects to an Access relational database. The database has 3 related tables (TextSections, LineItems, Cycles) that I'm loading into my dataset. I've set up two foreign key constraints and want all changes to cascade through the related records in the child tables. I cannot get the cascades to reflect through.
For example, when I delete the parent record, the children records remain (in the database - they are removed from the dataset). Also, when I modify the parent record (change the Description field for example), the change is not reflected in the dataset datatable that holds the children records - unless I go through and ReLoad all of the data from the database and re-Set the constraints. I have set the .AcceptChanges, .UpdateRule, and .DeleteRule to cascade, and have also set EnforceConstraints on the dataset. Why aren't the changes cascading through the children?
Below I've pasted (1) the Load Routines for my datatables TextSections (parent), LineItems (child), and Cycles (child of LineItems); (2) the method that creates the constraints in the dataset, and (3) The Save routine for TextSections.

I'm using a dataset class written by others who have defined the foreign key relationships between tables using the tools in the schema diagram. I'm binding the dataclass to a windows form. I'm running into an issue where I have an existing header record and I'm trying to insert data into a child table via a grid programmatically. The child table contains all keys for data. As the grid is bound to a binding source, I'm simply adding rows directly to the grid programmatically.
When I attempt to save the data, I get the error ForeignKeyConstraint FX_Activity_UserRoleActivity Requires Child Key Values (4) to exist in the parent table. The value (4) is one of the foreign key values and it does exist in the parent table. The error occurs when I tell the bindingsource associated to the child table on the form to EndEdit. Looking at the XSD file for the dataset, both foreign keys are set up for 'Both Foreign and Key Constraint' with Cascade set for both update rule and delete rule. Accept/Reject rule is set to none.
Running a SQL trace, I confirmed that SQL Server is not generating the error, so it is occurring on the client application somewhere. First what does the error actually mean? Second, does the configuration of the foreign key relationship in the dataset's XSD file have anything to do with it? If so how should the foreign keys be set up between the tables? If it isn't how would you go about troubleshooting this issue as stepping through the code ends with the .EndEdit call to the binding source.
