View 2 RepliesWindows - Access The My.Application Object From A Form Or Control Object?
Jul 6, 2011I have a solution with several Projects in it. There is a Windows App project (called ImportClient), and a Class Library (Import.Library). The Import.Library has functions to perform data imports (I have other applications in the solution that also need to call it). But the interactive application, I want to be able to pass in some form controls, and have it update the GUI. No problem. But, I also want to execute a DoEvents() so that the loop execution doesn't hang other interaction to the app.
So, ImportClient has a reference to Import.Library. But I can't add a reference to ImportClient to the Import.Library, because the compiler complains about circular reference, etc. I don't know how else to define the My.Application object of ImportClient as a parameter to the data function in ImportLibrary.
(I realize this is a dumb question - problem is, for this project I have a tight timeline, and haven't learned how to do the BackgroundWorker process. If you think I could pick it up quickly, I'm open to some hints about how to update the progress bar on the GUI, and how to pause / cancel the background task.)

View 3 RepliesHow To Import Form1 Object Value And Calculate It In Form2
Mar 18, 2010So the application I'm writing code for is this:
A fancy bed and breakfast offers the following, though somewhat usual, rate structure:
Single room $150 per night
Double room $175 per night
Family room $200 per night
Suite $ 250 per night
The bed and breakfast also offers the following meal plans
Breakfast only $10 per day
Breakfast and lunch $15 per day
Breakfast lunch and dinner $25 per day
Create a VB 2008 application with two forms. One form holds the room type (Single, Double, Family and Suite), and the other holds the meal plans. The user should select a room type and a meal plan, and the application should show the total charges multiplied by each day the user stays at the bed and breakfast. So far I've created one form with Bed plans and the second form with meal plans. First form has a continue button so that I can load second form and the code for that event is:
Dim SecondForm As New frmSecondForm
SecondForm.Show()
Then I've meal plan choices in second form and a text box for number of nights and a display cost button. So when I click on Display cost button, I want to be able to add the bed plan into total cost. How do I connect these two forms?

View 9 RepliesAssign A Type To An Object At Runtime In .net Or C#?
Jul 23, 2009I have an object, o, and a type, T. I'd like to use reflection to change object o to type T at runtime without instantiating it.The equivalent at compile time would be:
Dim p as Point = Nothing I know how to use Activator.CreateInstance to create an instance at run time that is equivalent to: Dim p as New Point()
But i don't want to do this. I have no knowledge of the type's constructor parameters and some types don't have a parameterless constructor. eg. Font. So, to sum up, I'd like a way of performing the equivalent of: Dim o as T = Nothing
In case you're wondering why I'm doing this, it's because I'm using a PropertyGrid on a form to edit types. If this is the first time for editing, say, a Font, then passing an uninitialised Font to the PropertyGrid makes the grid display the default values.
I tried 'o = GetUninitializedObject(T)', but the PropertyGrid either wants a properly initialised object or an object, with a defined type, set to nothing.
I've actually solved my particular problem here: how-to-use-the-property-grid-in-a-form-to-edit-any-type
, but i'd still be interested to know how to assign a type at run-time without the use of a wrapper class (which I was lucky enough to be using).

Calling A Function / Assign Property Of An Object Inside An Array
Oct 5, 2010So if I create an object test, and it has a property color. When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able to let it know what type of object I am trying to work with inside the arraylist. In code maybe something like this

[2005] Position Form2 Directly Under A Control On Form1?
Jan 23, 2009What I'd like to do is position Form2 underneath the Label on Form1 when the "down arrow" button is clicked. (Basically Form2 should have the same "Left" as the Label on Form1, and its "Top" should be the Top of Label1 plus the Height of Label1.) Please see attached images for further clarification. (I did something like this in VB6 with the SetCursorPos API and the Screen.TwipsPerPixelX and Screen.TwipsPerPixelY properties, but I'm sure there is a better way to do this in .NET.)
