this is my absolute first attempt at the mschart control in a winform, so any help would be appreciated - i have sales reps that issue quotes to customers and would like to plot number of quotes by month using the mschart control.I have a dataset populated with a single table with 2 columns in it - sales_rep and quote_issued_date (there's more, but i'd like to only focus on those two because they contain all the info i need)i have a windows form with an MSChart control dropped on to it. I'm trying to get this to work on a 'column' chart type.i'd like to count the number of records in the dataset per sales rep per monthi'd like to get the x axis to be months in the year (fixed, not drawn from the data) - jan thru dec.
i'd like to get the Y axis to reflect the highest count of rows per rep per month + say....10% (so the graph doesn't peak out at the top every time, it would be more for aethestics)i'd like to get the columns displayed in the graph to be each rep, each month (ie for january john has 10 quotes issued, bill has 5, tom has 31 - for feb john has 3, bill has 10, tom has 19 - etc etc etc) - because the form is just a quick visual, i'm dumping any code in the form load event and calling it good.
I have a database with testmarks of - lets say 30 students. I would like to print a distribution chart using Mschart. The values will be loaded into an array ChartData(30) The distribution chart X-axsis should range from 0 - 100 and the Y-axsis 0 to the average amount.... hopes it makes sence....
I have browse the net and can not find any examples of code that i can use to see how the Mschart control works. Can someone please help me with some examples.
I am trying to bind an Access database to a MSChart control in VB Net 2008. I have a test database populated with four fields SAMPLE-DateTime, Values-Number, MAX-Number and MIN-Number. I'd like to only display the rows that fall within a specific date range but I'm running into a problem when i try to execute the following command:
I have a problem regarding solutions that I have to develop. I work in a company which has a standard of NET Framework 3.5.Also the company has bought Visual Studio 2010 Premium for me.I need to develop an application in which I have to insert som Charts. Previosly in Visual Studio 2008 Express was very simple because I have installed MSChart Addon from Microsoft.The problem with VS2010 Premium is that I cannot create aplication with charts in NET Framework 3.5, only in .NET 4 but I cannot develop solutions in NET Framework 4.0 because, like I have said, the company standard installation is NET Framework
i'm having a problem with AxisX interval labels. I want my AxisX length to be exactly one minute and labels showing every 5 second. So it should be 12 labels all the time. But after that minute passes, I'm getting 13th, than 14th label and so on.
Imports System.Windows.Forms.DataVisualization.Charting Public Class Form1 Private minValue, maxValue As Date Private rand As New Random()
know the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse?I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects.I've had a look in reflector but it's one of those controls where most of the implementation is not viewable.
ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this?
Is there any way to scroll in a StatusStrip when its controls exceed form viewing area? My StatusStrip acts as a taskbar with a lot of labels (acting as buttons) which if there are too many might go outside the bounds of the screen.
What is the best way to bind a property to a control so that when the property value is changed, the control's bound property changes with it.So if I have a property "FirstName" which I want to bind to a textbox "txtFirstName" text value. If I change FirstName to "Stack" the txtFirstName.Text also changes to "Stack".
I'm using .NET 2.0 Windows Forms and want to add "drawing" components such as lines, rectangles, etc.. I've done this before in MS Access, but I can't seem to find similar things in teh Visual Studio 2005 IDE. Where do I need to look to find these elements?
I am currently developing a WinForms application in C# and require a table control that can contain other UI controls.In the following example, I would like the Links column to contain link label controls:
I have a question about the webbroswer control regarding anchor tags. Is it possible to programmactically in vb.net go to an anchor tag in a webbrowser control? I would like to ideally provide a combo box drop down on the winform form and control which part of the html page the user goes to when the user makes a selection from the combo box.
In a WinForms environment, I want to wait a specified amount of time before hiding a user control, but I don't want to freeze the entire UI. I can't kick off to another thread because I have to service the UI components on the thread they were created on. What is the cleanest way to do this?
I would like to have the tabs on my TabControl displayed on the left, or sometimes right. Unlike the System.Windows.Forms.TabControl, however, I would like the text to remain horizontal instead of being rotated by 90 or 270 degrees to the horizontal. Here are a couple of pictures illustrating the concept. Though I could write code to do this myself in about an hour or two, I just thought I'd ask first if there is any existing Winforms control that implements such feature.
I am trying to change the UserAgent of the WebBrowser control in a Winforms application.
I have successfully achieved this by using the following code:
[DllImport("urlmon.dll", CharSet = CharSet.Ansi)] private static extern int UrlMkSetSessionOption( int dwOption, string pBuffer, int dwBufferLength, int dwReserved);
[Code]....
The only problem is that this only works once. When I try to run the ChangeUserAgent() method for the second time it doesn't work. I stays set to the first changed value. This is quite annoying and I've tried everything but it just won't change more than once.
I've got a WPF control hosted inside a Windows Forms form via ElementHost. My WPF control (let's just call it WpfControl for the sake of an example) contains a variable that I'd like to expose to my Form.
I have a question about the webbrowser control that I hope someone can answer. I am working on a document retrieval and storing class that uses HTML to display and save data. I want to use the webbrowser control in winforms using VB.Net. I only want to store the fields values in the html document, not the whole document. I am hoping to use labels in html and read them with the DOM of the web browser control but am not sure how to do this.
Has anyone done this before and could someone please provide some sample code on how to do this?
What I hope is relevant code below, I would like the User to be able to Right click when hovering over the PictureBox container of a User Control and pop up a menu which allows a User to check or uncheck an item in the context menu. How can I acheive that?
I have a custom UserControl that contains just one TextBox. When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).
How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:
Private _Enabled As Boolean = True Public Shadows Property Enabled As Boolean Get Return _Enabled End Get
I'm trying to create a button that will hide the panel that I have docked at the centre of my user control. [code]This works to an extent. However, when the bottomPanel is set to Fill it seems to fill the entire control, and not just up to toolStrip1. Can anyone tell me why this is happening, and how to correct it?
There is a panel which contains 2 components: a label and a TreeView. The hierarchy, obviously, looks like this:panel1 // handles Enter event
- label1 - treeView1
I need to do some UI updates when user starts interacting with any of these 3 controls. My attempted strategy was to catch the Enter event of the panel, which would fire when user clicks a label, or TreeView. This way, I can write only one (1) event handler instead of several. While it worked for the TreeView, it didn't work for the label. When I click the label, I don't get the Enter event on the panel. Whats different about the label control? I could handle the Click event of the label. At the same time, I wonder what the other solutions might be.
In vb.net I have one panel in which multiple picture box controls are added. When a double click is made on picture box, I want to save image of it. So how to know on which picture box control in panel double click is done?
In C# Windows Forms, a user control's InitializeComponent is called from the form's/control's constructor. When I create same scenario in VB.NET I don't get a constructor, and I can't locate a place where InitializeComponent is called.I need to call my code between InitializeComponent and when the control's Load event is raised, preferably still in the control's constructor. How do I do this in VB.NET?
I'm trying to bind a WinForms TreeView control to some user-defined objects. In particular, I'd like to bind aTreeNode.Text property to myObject.Name. My strategy is to create xTreeNode, a subclass of TreeNode, add a DataBindings collection, and expose its Text property. This would allow me to write some code like this:
Dim oBinding as Binding Dim bs as New BindingSource bs.DataSource = myObj
In a Windows Form application I have a Form with a UserControl that contains a child control. I have an event handler for the child control's Validating event. On the parent UserControl I call the ValidateChildren() method. But the event handler for the child control's Validating event does not run. The CausesValidation property is set to true on both the parent UserControl and the child control. Is there any reason why the Validating event handler would not run?
The child control is a custom control derived from Panel. It contains two RadioButton controls, both of which have their CausesValidation property set to true.
