I want to make pictureboxes move from the top of the screen to the bottom of the screen (easy) when they reach the bottom I want them to cease to exist (do-able). But i want to create new ones that keep coming from the top. create an endless amount of pictureboxes while running the program?
View 5 RepliesIf I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

View 7 RepliesI need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

View 3 RepliesI use serializer classes for storing data and each class can hold an array of objects for the same class which is a key feature of the class. I declare this array as so:

I have to ask my first question at some point, so here she goes.I am trying to create a dynamic list of objects. The objects will have several types (String, Integer) associated with them. Currently I am forming a Collection as I instantiate new objects.Is there a prefered to map this collection to, say, a Datagridview? Will I have to Iterate through the collection and add the rows at each iteration?Would I be better served using an ArrayList or something else over a Collection?

threads that watch folders and process files. This works fine, but every time needs change to add a new folder or just change some existing rules I have to go in and change the program. I want to builda front end that storesprocessing infofor each watchfolder. The program would then read the configs and build the threads based on them. I cannot find a way to loop through creating the threads.

View 2 RepliesIs there a way to dynamically create an object using a string as the class name?I've been off VB for several years now, but to solve a problem in another language, I'm forced to develop a wrapper in this one. I have a factory method to dynamically create and return an object of a type based on input from elsewhere. The provided input is meant to be the class name from which to create an object from. Normal syntax means that the entire class has to be explicitly spelled out. To do it this way, there could literally be hundreds of if/then's or cases to handle all the available class/object choices within the referenced libs:
If c_name = "Button" then obj = new System.Windows.Forms.Button
If c_name = "Form" then obj = new System.Windows.Forms.Form

I am trying to maintain a total for multiple collection objects in a class. When I create a new object, it resets the total to zero, only adding the current value being passed to the function. I have tried to use a static variable, create a second variable to hold the old total while adding the new value. The base class holds the total value, while the sub class creates the new object that holds information. I am passing the new value to a function in the base class adding the new value to the total when each new record is created.

I am trying to add some scripting to my VB.NET 2010 Windows Forms Application.I have figured out how to compile and execute VB.NET code stored in an external script file from within my app using Microsoft.VisualBasic.VBCodeProvider.CompileAssemblyFromSource and InvokeMember. I can also pass and return parameters to the code in the script file.In VB6 using the VBScript Host control, I could expose instances of objects in my app to the code in the VBScript.How do I do this in VB.NET?I'd like to expose a form object (the main form for my Windows Forms Application) to my VB.NET script.I don't want to pass the form as a parameter via InvokeMember.[code]

I wish i could execute my code from vb.net but sometimes it doesnt want to work because im referencing the 32-bit version script control and not the 64-bit scripting environment.
So my goal out of this is to find a 64-bit scripting component dll or library that i can use for executing a wsf file thats mostly written in vbscript but has some xml from the windows script host.Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. - "Sherlock holmes" "speak softly and carry a big stick" - theodore roosevelt.
