I have a form as Dashboards. I want to automatically refresh data without the data being read from the database and the user are shown.What is the best late for this scenario? I did this using a timer, but the best for this scenario is late?
I currently have a sub that has a string builder that I'm wish to use as the content of a CSV which I will email later from a webpage. My stringbuilder is creating the content for the CSV but I don't know how to create the CSV dynamically (I don't want the CSV on disk).
Private Shared Sub BuildClientTrustBalanceCSV(ByVal sb As StringBuilder, ByVal clientsWithTrustBalance As List(Of NonPaymentHistory)) If clientsWithTrustBalance Is Nothing OrElse clientsWithTrustBalance.Count = 0 Then
I need to create a label for every cell in excel that has a value depending on search criteria.Depending on what number is searched i need to display all cells in the row in different labels. There could be one label that needs to be created or many.Do i have to have each variable named differently or can i just use one label tag and give each label a different label.location = (x, y).
I was wondering if some of you can help me with a problem I can't seem to get around. I've got a database that contains a list of users who are connected to an application. The usernames and number of users connected will be random. What I need to do is to display two dynamic text boxes and also have a dynamic tooltip for each of the text boxes for each user displayed. If you look at the attached screenshot I drafted up, I'll only use the first user 'John' for this example.I will hardcode my example because getting the data from the database isn't the issue I'm having. My problem is figuring out how to make the text boxes and tooltips unique for each time someone visits the form. I would also like to be able to set the text within the boxes as well. So, I would need two textboxes for John called:
I am attempting to create a long range calendar that dynamically loads (and unloads) event data as the user scrolls left or right through time. I'm really struggling to figure out how to lay the basic framework of the UI out and how to dynamically build the interface as the user scrolls by clicking and dragging the mouse in the view area. See the image below for a basic diagram of the intent. Each slice would have potentially multiple rectangles in it for events that occurred on that day (slice). I would like each slice to be a canvas to allow me to position those rectangles appropriately.
There are a few problems that I am not yet sure how to tackle but this is the first big one that I've been mulling over for a while and can't quite wrap my head around:
I know how to dynamically create controls but how would I go about adding things to one end of the scrollable content while removing things from the other depending on the way the user is scrolling?
I'm trying to create a dynamic jagged array. That is, one that i can increase the size of at runtime. Maybe its easier if I show you. I have a folder containing a varied number of files. What I want to do is set up a jagged array, with the file contents as the second array. So kind of like this:
However, it throws a System.NullReferenceExeption when I try that. In addition, I don't understand jagged arrays all that well....Here is my code (that doesn't work). The jagged array must be accessible by other methods.
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?
I'm triying to create a dynamic query to Entity FW (i'm using Self tracking Entities over EF)
This is what i'm doing:
Public Class Specification(Of TEntity As Class) Private _predicado As Expression(Of Func(Of TEntity, Boolean)) Public Sub New(ByVal columna As String, ByVal condicion As OperadoresComparacion, ByVal valor As Object)
Currently I create a thread the following way (the normal way)
Public loginThread As Thread Public loginThreadStart As New ThreadStart(AddressOf LogIntoWhatever) Public callLoggedIn As New MethodInvoker(AddressOf loggedIn)
However, what I want to be able to do is something along the lines of (this obviously does not work, and is entirely pseudocode)
dim i as integer = 0 for i = 0 to i = 25 Public loginThread(i) as Thread Public loginThreadStart(i) as New ThreadStart(AddressOf LogIntoWhatever) next i Public callLoggedIn as new MethodInvoker(AddressOf loggedIn)
Where I could change 25 to whatever I wanted and have that number of threads created. They would all be running an identical sub which does do not make calls of any kind to each other, they don't need knowledge of each other. Is anything like this possible?
I'm a junior VB programmer and looking for some advice on this subject. I'm trying to create a chunk of code that will create dynamic storage for variables for use later by dynamic custom controls.
For example: An INI file might have an entry in it that looks something this: .... [var1] <-- this becomes the Storage name description=My Variable type=System.Int32 <-- this could be any valid VB type last_val=456 <-- Other code would save the last value ....
And I want to access the data using a standard "property set" like so after it's created: var1_reference.value = 55 I've tried using a generic class which works ok as long as I declare the variables at design time from within the design environment. But when I try to create them from the INI file it gets messy.
Here's the simple generic class i've constructed to test this: Public Class GenericVar(Of T) ' ' Generic Symbol Class for data storage ' Private VarName As String Private VarType As Type [Code] .....
Also, as each object is created (and they could be different types) I store a reference in an array to make it easier to keep track of, but I'm having a hard time getting access to the objects and their properties, and certainly cant seem to assign an event handler to it once its in an arraylist because the design time code doesn't know what "Type" it is in the arraylist of objects.
I have 10 textboxes. I want to make a certain number of these textboxes visible. The user enters a number from 1 to 10 to determine how many textboxes are visible.The textboxes are named textbox1, textbox2, .... , textbox10How do I set up a simple for loop to accomplish this?
I'm looking for a way to create PDF with dynamic content. When you google for it, you get 1000 hits on how to dynamicly create PDF's, but thats not what I mean.
I have a WPF window appliaction that I would like to build the functionality to have a dynamic style (font family, weight, size, etc) that is stored in a SQL database allowing a user to specify the type of style to use on control's such as ListView's and labels, etcI have started defining styles in the Application.XAML file and am not sure if this is the best approach to achieve a dynamic style.
I currently use SiteMapPath to generate a breadcrumb for my ASP.net 3.5 (vb.net) pages and it works great.
Now I am trying to figure out how I might be able to use the same control to build a dynamic page title (in the tag). I want a reverse path listed, but the SiteMapPath control includes links and bunch of styling spans. Is there any way to remove all of that, and just get a plain path with separators?
For example, Let's say we are on the "Press Releases" page inside of the "About" section of my site.
The breadcrumb shows up as:
Home > About > Press Releases
I want to have the page title be:
Press Releases - About - Company Name
So I need it to reverse the order, drop all spans, links and styling (since this is inside the tag) and drop the root node "Home" and then add the company name to the end. Since my menu nav and breadrumbs are all driven from the sitemap file, I thought it would make sense to try to make the title do the same.
Currently i only managed to implement the google map(static) into my application,but i want to replace it with a dynamic map. Is there any website or example for me to refer? I tried reading up google API website, but i still dont get it.
I'm trying to create an array of checkboxes dynamically and also want to put event to those checkboxes. For example: I have a array of checkboxes - Chk1, Chk2. I want it to work this way: When I check Chk1, I want to disable Chk2, and when Chk1 is unchecked, Chk2 is enable, and vice versa.
I create multiple dynamic pictureboxes and it are to many to add them all manually, is there a way I can e.g. use an integer which adds up every time a new picturebox is made. Then I want to add the same code to every picturebox. Now it creates the picturebox and moves it to the next spot and doesn't create a second. I am using this code if its helpfull:
