Multi Column List Box Array Resets Before Adding Next Values
Mar 13, 2010When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]
View 1 RepliesWord 2007 Adding Adding Values To Combo List Box
Jun 7, 2011I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?

Adding Values To Array?
Feb 24, 2012I am trying to run an event which will search through the different files in a given directory. The goal is to have it search for all files that begin with 'SP_', which are .sql files containing Stored Procedures. I would then like to add the full text of these Procedures to an array to be used later. This is causing an error when run, which I believe is because 'FullProcedureArray()', the string array I am trying to load does not have defined boundaries. When I declare it as 'FullProcedureArray(7)', or with some other value, it appears to run fine. But I don't want to have to hard-code a boundary for 'FullProcedureArray'; I would rather let it be defined by whatever the number of files in the folder is.
My question: Is there a way to declare 'FullProcedureArray' without having to give it an absolute value? I may just be missing something painfully obvious, but I haven't worked with this type of array much in the past.
Dim AppDataLocation As String = "C:FilesTestFiles"
Dim ProcedureArray As String()
Dim ProcedureText As String

Adding A Bunch Of Values To A List(Of T) Collection At Once?
Mar 12, 2010I am creating an instance of a Generic List collection and I am surprised to find that I can't add more than one value to it at a time. I was thinking there was going to be something like what you can do with arrays, where you can add a group of values to it at creation. I saw the AddRange method, but that seems to add another collection to the end of this collection, which is not what I want. So my code is:
vb
Dim MyList as New List(Of String)
MyList.Add("John")
MyList.Add("Bob")

VS 2008 Adding User Values To A List Box?
Dec 10, 2009I have 1 list view box that has 2 colums. one for the product and the other for the cost. My question is how would I allow a user to add values to that?
My basic layout is, There is a settings window that has about 10 rows of text boxes and 2 colums. I want the user to be able to type in multiple items and prices then hit save and exit for the products to save to a my.setting
and then use this my.setting to bring the users lists up in a list view box.
Since the product and the list price are paired I also need to keep them together in there pairs.

Adding Variables Of Array To List Box?
Sep 2, 2010Ok so I have an array and wish to add the variables of the array to separate lines of the list box. I came across this which in some ways worked but also didn't. The second thing mentioned on the page was to us:
ListBox1.DataSource = Form2.Title This works the first time you run it but if you try to run it again nothing happens. So using the above or something else how can I get it to update the list box? Another thing I tried was to use the DataSource method but instead to clear the list box first, but that turned up an error

.net - Adding New Object To Generit List Overwrites Previous Values?

.net - Convert Resultant Values To List Of Strings In Linq?
Oct 1, 2010I'm having issues with returning a list of strings of the .Value of a Linq query:
Dim details = <Details>
<Vector size="5">
<Item>Syntactic Structures</Item>
<Item>Introduction</Item>
<Item>The Independence of Grammar</Item>
[Code]...
Is correct in that it returns the list of XElements I want (items 1 - 4, base 0), but I really just need a list of strings for the .Value of those XElements. Maybe I'm just dense here, but anything I've tried in the chapterTitles query isn't working (appending with .ToList.ToString, etc.). details.<Vector>.<Item>.Skip(1).Take(4).Value just returns the first XElement's value.
Convert An Array Of Any Object To A CSV List?
Feb 28, 2009I am using Linq to convert an array of any object to a CSV list:String.Join(",", (From item In objectArray Select item.ToString()).ToArray())
This is giving me the strange error: "Range variable name cannot match the name of a member of the 'Object' class."I can get round it by wrapping the string in a VB StrConv method, with a setting of "Nothing":String.Join(",", (From item In oArray Select StrConv(item.ToString(), VbStrConv.None)).ToArray())
However, this seems like a bit of a hack and I would like to avoid it.Does anyone have any ideas when this problems occurs, and any better ways to get round it?

Convert A List(of Long) Into A String Array?
Oct 26, 2009I want to convert a List (of Long) into a string array.
Reason: it's a list of database IDs and I want to make a comma delimited string to pass into a stored proc.I tried this:
Dim commaDelimitedList As String = String.Join(",", itemIDList.Cast(Of String)().ToArray)
but I'm clearly not using the Cast correctly since it throws an exception:
System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.String'..
Is there a way to get Cast working for this, or am I stuck with ConvertAll and a delegate function?

Convert Positive And Negative Math.Sin (waveform Output Values) Into (unsigned) Byte Array?
Apr 19, 2011I'm creating an emulator for a device to simulate wave forms. My challenge is that when I try to convert the output of the following code, I can't convert the Math.Sin's double output into byte values that lend themselves to the byte array format required by an existing graphing control as listed at bottom below. I''m not sure how to handle this when the sin function creates negative values but the byte values will need to be positive and basically 'shifted up' so that anything over 127 is negative. (0 - 255) unsigned. BitConverter.GetBytes has been suggested but THIS is the result of that attempt.
