I want to add an array to the class `StopwatchStorage` but can't figure out how without some ambiguous warning or error popping up. The Array will contain TimeSpan type elements (essentually an array of Stopwatch.Elapsed values)
How do I declare and add a dynamically sized array to the class. I know that I will have to use the UBound function each time I want to add a new array.
I have 5 pictureboxes on my form and would like to but then in a collection or array to use them in a loop. I would like to use the FOR EACH loop... but how.. Th pictureboxes are placed in a Table. Here is my code so far.
I am working with an XML web service using VB.NET, created using VS 2010. One of my web methods returns a collection(type that inherits from list) of custom objects. It's a simple return statement, it is my understanding that .NET handles most of the tricky protocol stuff as well as serializing/unserialzing of objects.
The issue is in my consuming application when I get the the return value of the web method that returns a custom collection I get an array of the custom objects. Is this normal behavior? It will be easy enough for me to take that array and insert it into a custom collection object but if I could I would like to skip this step.
Working on a project that tests up to 16 PC boards. The test routines are on a a backgroundworker thread. I want each PC board to perform the test routine on its own thread, so I would need up to 16 backgroundworkers.How do I go by doing this? Do I put 16 Backgroundworkers on the form? I tried to do it programmatically but I can't declare an array of backgroundworkers because withevents variables can't be typed as arrays. I guess I just need a kick in the right direction.
I have a group of boxes witch will all hold data input by the user. I am using an arraylist to store these, or atleast I am hoping to. So, the problem I have is getting the data to actually save to the arraylist. It keeps giving the error saying that type string cannot be converted to array list.
I want to know how can I possibly copy a table with multiple columns and rows into an Array or Collection in VB.NET.I want to know the best solution because I want to use the code for 2 different tables and do some comparisons, and the second table has too many records.I was wondering if in VB.NET there is something similar to Hashmap used in java and a table could look like the following
How do I Display A HashSet As Either A Collection or an Array in the PropertyGrid.I wish there was some Attribute that allow me to display IEnumerable as an Array...but so far my attempts to do that have failed!My current solution is unacceptable in the new places I want to use it in
I am using 2 dimensional arrays for my work. My problem working with them they are incredibly slow for my work. I am starting the array with randomly assigning values (non zero) to the array. Most of the array values are zeros as shown in below form (e.g. 5 x 5):
I have a string array called m_DirFileList and a collection called myFileCollection. I'm trying to loop through the items in the collection and store each one in the string array. It's not working though.

I tried this vb Dim matches As String() = Regex.Matches(tmpFieldContent, strEmail).Cast(Of Match)().ToArray() But it didn't work, as vb says 'Cast' is not a member of System.Text.RegularExpressions.MatchCollection'.
Is it possible to have a two-dimensional array/list/collection such as the following. The first dimension is to have 2 elements, 0 and 1. The second dimension I would like to be able to have a different number of elements for each of the elements in the first dimension. To explain better, I'd like X in array (0, X) to go up to say 4 and Y in array(1, Y) to only go up to say 2.
So there would be: array(0,0) array(0,1) array(0,2) array(0,3) array(0,4) array(1,0) array(1,1) array(1,2) But no array(1,3) or array(1,4).
I'd also need to be able to use Redim Preserve to increase the size of the second dimension for each of the first dimension's elements.
I have a parameterized query that displays the info (name, phone number, email addy) in detailed text boxes vice a normal DGV. I have coded a button to open outlook and populate the email address, but what I would like to do is have the user click another button that would add each email address into an array or collection from the desired records. Then, when they added all desired recipients to this "collection" they would hit the email button, which would open up outlook with the To: box already populated.*
I have looked into dynamic arrays , generic and special collections but am not sure what the best way forward is. When using the dynamic arrays I didn't really get anywhere, I couldn't seem to figure out how to redim with each addition of an email address.
Dim emaillist() As String Dim listings As Double Dim addy As String
I created a custom class for a custom object. I instantiate like so[code]...
Now, I have two problems. First, right now this is just overwriting the same object properties, again, and again. I need to somehow dynamically name the object. Then, I need to place these objects in an array so I can iterate through them...
I am working on my first VB application and have run into a problem. I am trying to loop through some data and displaying them in labels. I am using a for-each loop but end up with different row with the same labelname. What I would like to do, is to assign a number to the labelname (mylabel1, mylabel2,...), but I can´t figure out how, and I cant find anything online that will work. Here are some of the code that I have made, where I could use a solution to my problem...
I need to bind a textblock.text property to a single element in an observable collection, or array element, and have the text update using the INotifyPropertyChanged or INotifyCollectionChanged, whichever is best.
Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.
Is it possible to bind a single textblock to a single array element? Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?
Is it good practice to store sub-collections of item X inside a parent collection of item X for caching 'filter-queries' which are performed on the parent collection? (They won't be used together (as in color AND type).) Or is it also ok to just Loop over the collection and return the correct entities in a temporary collection?
I have been researching for a couple of days now and to no avail. Does Anyone know how to make a custom collection that take advantage of the collection editor? I would like to be able to have 3 Color Values, 1 Boolean and 1 String.
I'm trying to support Basic.NET on my framework so I'm trying to convert C# 4 code to Basic.NET 10. Microsoft is committed to "co-evolve" these two but I'm having a problem with collection initialization... I found that I can initialize a collection much like in C#:
I've got the following ADO.NET Entity Framework Entity Data Model:I want to find all the Policyholders with both a Service of a given Id and also a Keyword of a given Status.
This LINQ Does Not Work:
Dim ServicesId As Integer = ... Dim KeywordStatus As Integer = ... Dim FoundPolicyholders = From p As Policyholder In db.PolicyholderSet.Include("Keywords").Include("Services") _ Where p.Services.Id = ServicesId _ And p.Keywords.Status = KeywordStatus _ Select p
The Where clause cannot search the p.Services and p.Keywords EntityCollections in that way.
currently in my application I have a Global Collection that is a Collection of Collections.Currently I am trying to add items/ elements to one of the child collections of the Global Collection but I am unable to use the collections methods of the child.When I assign a variable to the child collection and return the collection it is just an object with the collection inside.
Ex: Dim GlobalCollection as New Collection Dim ChildCollection1 as New Collection Dim tempCurrentCollection[code]......
I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error. The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal. I have already checked permissions on the page from the CMS admin console, and it is public.
The error message is as follows:
Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
I am using a MySQL Server on the net and a Windows Forms client program, which connects to this server.
I want to use SSL and have prepared everything, that this can be used. My primary question now is as follows:Where / how to store the files for the SSL certificate as best way? As embedded resource? as external file? As part of the My.Settings environment?
I have been trying to do this for about a month now (hard to get answer quick because of school), but i need to decrypt a file into memory. I know you have to "write all bytes to memory" but i have two problems with that, 1. I have never touched on that itself and don't know how to write the bytes of an executable to memory, 2. I still wouldn't know how to decrypt it in memory. Right now my code is:
ElseIf entype = "rc4" Then If File.Exists(thepath & exerandname) Then Kill(thepath & exerandname)
it checks if the file exist then deletes it, then it opens the file and decrypts (_4reversecr.enc) the file(Cutter(1)) with the key (key)?
I'm making an installer that needs to have information stored inside the exe itself.I cannot use my.settings because it is stored outside the application and if it is changed and the exe is moved to another computer it will reset to default.
And I cannot use resources since I cannot add/edit resources after the application is build.
Is there any way I can store and change info even if the application is moved to another location?
I was reading an article about isolated storage and thought of doing the following.Encrypt files.Add them to Zip.Unzip the file,decrypt the content and copy all the files and folders into an isolated storage and then load a specific file into a web browser and launch lets say an HTML page I got stuck on the Isolated Storage thingy
here is a part of my code
'So far i unzipped the content of the Zip file 'Setup file streams to handle input and output. fsInput = New System.IO.FileStream(strInputFile, FileMode.Open, _

I'm trying to access a USB Storage device, however the device although appearing in the commputer / Drives section, is not allocated a Drive letter, thus when I itterate through the attached drives link text it does not appear, I've taken the "Location" from a file on the drive (properties) and it comes up as COMPUTER/Q1/Datacasts but this doesn't work when I pass it to the FileInfo Object (network drive cannot be found) And I'm at a bit of a loss at which way to procced
I am attempting to add a document storage module to our AR software. I will be prompting the user to attach a doc/image to thier account. I will then put a copy of this file into our folder so that we can reference it without having to rely on them keeping the file in its original place. This system is not using a database but instead its using multiple flat files.
I am looking for guidance on how to handle these files once they have attached them to our system. How should I store these attached files? I was thinking I could copy the file over to a sub directory then renaming it to a auto-generated number so that we do not have duplicates. The bad thing about this, is the contents of the folder can get rather large.
I have an ASP.NET site in a web server and the images are stored in NAS (some kind of lacie external storage), I tried UNC and other things but no success.how can I access images from external storage in ASP.NET
