If the correct response is selected, the examinee gets 1 point, else 0. At the end of the quiz, the examinee can click a button that will add up all the correct responses & display the % correct. How do I program the button to do this given that data are on 7 different forms? [URL].

View 12 RepliesI am trying to design a basic version of spaceinvaders. I have 6 pictureboxes on my form and the idea is to add a value to the picbox.top property that moves the boxes down at a certain time and speed that i have set in my timer control. The problem i have is i am trying to set properties for all the pictureboxes at the same time by using arrays.
An example would be
dim mypic() as picturebox = {pic1, pic2, pic3, pic4, pic5, pic6}
pic1.top = 10

I have a very simple 2D array, it holds a list of song titles, their genre, and their runtime. frmMain loads the array from a text file and allows me to manipulate it and boil it down to a desired (implicitly sized) playlist. i want to THEN pass that playlist array to a second form, frmPlaylist The problem i'm running into....When frmPLaylist calls the Property from frmMain I receive an error that VB cannot convert the string value to a two dimensional array. Simplified...frmPlaylist is all locked and ready to receive a 2D array, but frmMain seems to only be sending a single string variable. on frmMain

I'd like to give a homework assignment to a person learning VB.NET. I'd like it to use basic inheritance and a variety of data structures including queues, lists, arrays, or stacks in a windows forms application. I was thinking of a pizza-ordering application. This would allow them to utilize some basic inheritance and practice using .NET UI elements.
View 2 RepliesIn VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?
My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

I've recently decided for my VB final that I'd like to tackle something my professor and I discuss constantly; portable game server apps.
What I'm wanting to do, essentially, is create just a rudimentary programme that allows you to check the server status of either the north American or European servers for the game Rift and just (instead of opening your default browser, which I know how to do already) displaying the info in a listbox inside the programme itself.
The information I have to work with (aside from the obvious direct .php link to the web page) is two separate .xml links that contain all the information that is contained on their webpage. I could easily just turn these .xml files in an access database but I want something dynamic rather than static, but I honestly have no clue of how to turn this info I have into something I can actually use in my programme lol.
I'm creating a system (for a project) that is based on a vet.I want to create a combo box that has a list of different animals (e.g. Dog or Cat etc.)and when an animal is selected,a group box, with loads of checkboxes inside appears. Then the user can tick a check box (a vaccine to be given to the animal) and the record is saved to a database.I have hard coded this to work, but I want a more sophisticated code set, that links to SQL so that when a new vaccine is to be added, I would only need to add it in a table, in the database. I don't know where to start for this could any one give me a nudge in the right direction?

Explicit run-time linkingDLL files may be explicitly loaded at run-time, a process referred to simply as run-time dynamic linking by Microsoft, by using the LoadLibrary (or LoadLibraryEx) API function. The GetProcAddress API function is used to lookup exported symbols by name, and FreeLibrary — to unload the DLL.
