I'm stuck on a problem that I haven't been able solve. I'm making a visual basic program that communicates with an SQL-database. The problem emerged when I tried to retrieve data from the database with the help of SqlDataReader and save data from every row to a list (Customer) with the help of Add-method. It turned out that eventually the list had correct number of objects, but the information was the very same in each object of the list.

View 4 RepliesAs Autodesk is going to discontinue VBA for their Inventor product in the near future I have been looking at other ways to run VB.NET in Inventor. To date it doesn't look like VSTA will be the replacement. Automation from an External VB.NET app is certainly possible, but leaves something to be desired for speed and integration. Compiled Add Ins are the Cadillac of choice but can be a royal pain to debug and develop. Autodesk now provides a lightweight VB.NET script interface called iLogic. It's main purpose is to allow extreme customization of Solid Modeling parts. The code actually resides inside the Part Model file.

I'm currently working on binding an objects properties to fields on a Form. Whilst I have managed to get it so that I can get standard objects to bind, I am having a problem figuring out how I would go about binding an inherited object.
For example, if I had a Client class (the parent class) and then two sub-classes called CompanyClient and IndividualClient. The CompanyClient would have an extra field company name for example.The problem I'm having is that I'm not certain how to set up the binding, as if I set up the binding against the Client class then I would be missing the Company Name property for the CompanyClient, if I set up against the CompanyClient, then it wouldn't work with the IndividualClient as it doesn't have all the fields.
I know I could get around this by having different forms for each of the different Client types, but as almost all of the properties are the same I would like to avoid this if I can.I was wondering whether anyone knows how I might be able to go about doing this

View 2 RepliesI have a windows forms application built in VS2005 and migrated to VS2008 that I "inherited" that occasionally will not show some of the objects (i.e. a button or something) when a user runs it. This is sporadic and does not seem to have any notable pattern.Are there any specific types of things I should be looking for that might cause such behavior? I tried looking at available memory and hard disk space issues and that did not seem to have any bearing on the problem.

In my software course, each time we submit an assignment, we have to include a document with the starting properties of each object in a form.

It's a real pain to scroll through the properties viewer and copy and paste each customised value for 30+ objects on a form... I was wondering if there'd be an easy piece of code or way about getting an (at least partially) automated printout/view of all the properties of the objects.
Was thinking some sort of private sub I could past into the bottom of the program and run on load, that gets all objects, and outputs the non-default properties to a report or something?
I have a VB class inside which one of the methods accepts an array of forms.

I'm trying to set up a system to resize multiple objects on a form (40+) when the form resizes.

View 10 RepliesI designed a form which contains about 50 objects all kinds including tableadapters,buttions,grids, tabs. What is the best way to optimize the loading with less time consuming. I cannot split objects in on different form as all the objects has to appear on screen as a requirement.
But my primary question here is, i designed this form with all these objects on a 15" monitor which fitted 100% on the screen. Now i am using 17" monitor when i open this form on run time, all the objects are appearing as designed but theres a 30% form area which is left blank. How can i make the form objects resize automatically on run time itself to fit on different size of monitor with no area left blank.
Background: My VB .Net application is a back-end solution that works with a proprietary Linux-based middle-ware messaging architecture developed by our company. My application references to the middle-ware DLLs, obtains connectivity, and subscribes to specific broadcasts with the middle-ware. When the broadcasts are received, it handles processes them and inserts/updates certain tables in a database. To do so, it has specific notification classes to handle each type of broadcast. These classes adhere to the inheritance model imposed by the middle-ware DLLs.
