Dynamic Draggable Labels On Chart For Notation Purpose
Jul 22, 2010
I am deveolping a charting program and have a need to have dynamic draggable labels on the chart for notation purposes. Everything works fine until I try to drag a label past the 32767 (16 bit limit).
Here is the code that I drag the label with:
If ISDRAGGING = True Then 'DRAGGING LABEL
If CURRENTLABEL.Tag = 2 Then
CURRENTLABEL.Left = 0
[Code] .....
I have tried to create a new label and override the Top value with a Long Value, but it still does not do the trick. Hhere is my attempt to overload the top value to an integer.
Public Overloads Property Top() As Long
Get
Return _Top
End Get
Set(ByVal value As Long)
[Code] .....
The charts are dynamically generated from a database and represent depths. Usually at least 10000 feet are plotted at 5 pixels per foot. So some labels will be created or dragged below this 32767 line regularly. Any way to be able to drag the labels past this limit, or possible another option to be able to view these long charts.

I can not figure out how to get the chart to display the labels. When I try and add labels, the lines get messed up. Also, if I try and do multiple lines it does not always work out very well. I tried different ColumnLabels and they behave very strange as well. What I want is to be able to have several lines. Each with their own label. And also, I want to specify text for each point at the very bottom of the graph. Let me know what suggestions you have. [Code]

I am trying to have a firm grasp of VB.NET and wondering if there is a way to use a double dot notation instead of the single dot notation people are normally accustomed to?The double dot notation that I want to implement is shown directly below:
PersonData.Birthdate.IsValid
Currently, the only way I know is by using the call shown below which I suspect is not using the full capabilities of .NET:
Validations.IsValid(PersonData.Birthdate)
My code is shown below:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
modVar.intDay = 25

I'm seeing a strange problem with the labels on the X axis of my charts. I've setup two chart areas and aligned them (which displays fine) and the user can manipulate the chart by selecting different date resolutions (Year, Month, Day, Week, Hour) and different time periods.
The issue I'm seeing is that if a user selects say Months as the date resolution the X axis label display is inconsistent. If a fairly broad range for the dates is selected the X axis displays absolutely fine but as the date range narrows the X axis starts to duplicate labels ( please see the attached images). The second Image had a date range of 1st of May to 1st of August and as you can see the labels are duplicated. This is my first go with the chart control so I could be missing something basic. [Code]

I would like to build a line chart which can redraw or change during a period of time with dynamic data. So that the x, y axis will change if out of range. The graph may be somehow similar to Matlab. I am using vs2005.

I'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.

I have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?

I am building a Windows Forms app without a border, so I have complete control over the interface. A few years ago I managed to create a VB6 app that I could drag the form using a control on it, but I cannot for the life of me remember how to do it, and Google has failed me.

Our programming teacher taught us to use the Hungarian notation (e.g. intMyInteger, strMyString,...) while programming.But I have heard somewhere this isn't actually used in the professional world. Is this true?

How do I dynamically add or remove a chart series on a WinForm. To date all my MS Charting experience has been dealing with ASP.Net charts with static sql select statment to a SQL Database. In the new project that I have been assigned I have different cities with different amounts of points that they want monitored. One city might have 3 an another might have 5 or 7 so I can't hard code the amount of series that I need. It needs to be set up so the amount of series can be flexible depending on the city selected and then display those points on the chart.

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?
