VS 2008 Arrays In A Drop Down?

Feb 21, 2010

I have been given an assignment which is to program a working payroll system in Visual Basic 2008.I have done most of it but I am stuck at the arrays.I would like my system to store all the staff name that the user adds on the system into a single Array for example in EmployeeNames(50). For example if the user enters a new staff in the textbox name and confirms it by clicking on a button, I would like that staff name to be stored into my Array EmployeeNames(50).

the statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "

VB6 Used Recordsetsor Arrays - .Net Framework In VB2010. Datasets, Dataviews. Tableadapters, Arrays. Enums ?

May 9, 2010

In 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 ?

Passing Arrays Through Fortran Dll From App Turning To Single Element Arrays?

Feb 2, 2010

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

VS 2008 2D Arrays And Mazes?

Nov 6, 2009

I have a 2 dimensional array. Im trying to use it to generate a maze via some algorithms. Its pretty much way over my head though.But thats beside the point. If i need each array coordinate to store multiple values (like if south, west, north, east has walls), what would be a clever way to do so?

For instance:1, 1 in the array needs to keep track of 4 values at least (as do all other positions).

Should i make it an integer value like "1111" and replace with 0's where the wall is gone? the first 1 being north, second being east e.t.c. Would you choose this option?If someone wants to do a bit more research, here is some info on mazes:[URL]..

I am toiling with the best way of doing this. So far, I am not having much luck. I have used arrays quite successfully in Java, but I am not sure that this is the best way to go here. I would have to get how many lines there are and read each line. Make the changes, and then go on to the next line. I think scanning the document line by line using a loop is the best way. However, I am not sure.

VS 2008 Working With Arrays?

Jan 28, 2010

working with arrays is not something I am too good at,Currently I have a form with 2 text boxes and a single button. I have two arrays, one populated with user names, the other populated with password. The user names and passwords match up in position in each array. I am thinking I might need to create a multidementional array of these two arrays.

[Code]...

If I do this however, any user name gets matched to any password, pending both exist. I would like to be able to compare the user name and password of a single user. Right now the user names and passwords are stored in separate arrays. Should I merge the two into a single array? If so how? And if so how do I go about matching the text box entries to the array(s) and making sure that the user name and password matches?

VS 2008 Byte Arrays - Getting More Values

Jun 11, 2010

I am having some major problems with byte arrays. First off the bigger array I have the more values go missing, I originally wanted to make a huge array and just dump like a 100mb chunk of memory in it but when I did that every byte in the array returned 0. So I experimented a bit and found 4kb to be the biggest chunk size to reliably not return 0.. ok I figured I'll just loop the 4kb and glue them back together later but no such luck, after being combined into the main array the bigger the number gets the more values that should be there just aren't.

Here's a code sample:
Dim retval(4095) As Byte
Dim combval(RLen) As Byte
For i = 0 To RLen - 4095 Step 4096
ReadProcessMemory(ProcAccess, i, retval, 4096, 0)
retval.CopyTo(combval, i)
Next i
WriteLine(combval(321603964))
WriteLine(ReadMemory(321603964, 1)(0))

So with the last 2 lines if I pull up some smaller number like 8 digits or so it reports back no problem but anything slightly bigger like the number i have written in there right now is just 0. After some additional research I discovered that the reason why 4kb is the max size I can reliably get is coz that's the size memory chunks are made of, "page" as they call it. Why the memory reading drops off at higher addresses alltho I suspect it has something to do with the way memory is structured and I am just not hitting the startpoint of a page anymore due to an offset or something somewhere.

Drop Down Box And Other Stuff In ASP.NET With (VS 2008)

Apr 13, 2010

I am trying to polish up a program a program that I have converted from a Windows Form in to an ASP.NET Web Application. I have several questions:

1.) I have a drop down box where users can select their variables, but users can also enter their variables manually into various text fields. What I want is for the drop down box to show a string like "Choose Variables" when ever the user enters their variables manually. I want this to happen without having to reload the page.

2.) In the Windows Form version of this application I had a RichTextBox that populated with data (line by line) after a calculation was made. I used "AppendText" in my Windows Form, but that is not available in ASP.NET, and neither is the RichTextBox. I tried to use just a text box but that isn't working right.
