The charting control has disappeared from my toolbox in VS2010. I know it was there when I upgraded to 2010 a few weeks ago. Both chart items are checked in the Choose Toolbox Items dialog but it doesn't show up in the toolbox. I'm pretty sure it was under the Data category. I tried resetting the toolbox but that didnt bring it back.

View 1 RepliesIm doing a project with .Net 4.0, Visual Studio 2010 and Visual Basic .Net.I needed to add a Chart (the new one included by default in .Net 4.0) that represents temperatures evolving with time, so I added the drawing points in the elapsed event of the timer every second.The graph is doing somewhat ok, but I need another functionality, and this is, every time I stop the timer, save the graph in an excel (.XLS or .XLSX) file. As by default the chart provides with a collection of the type "System.Windows.Forms.DataVisualization.Charting.DataPointCollection", I would like to know if there is a way to create an xml and put the info of those collections in the excel file.I have looked around but I didn't find any similar example, last thing im thinking about is to use an iterative way to manually write in the excel file, but maybe its too much time consuming as the iteration will be of several thousands seconds.
View 1 RepliesGreetings. I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.
Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.
I tried a repair re-installation. The same things happens.
I can set properties etc. programatically, but that sorta defeats the point of an IDE, not so?
For some reason a control on my form has disappeared. I can select it in the properties window and view all the properties (Visible = True) but I can't see it. It also doesn't appear when I run the form. How can I delete it, or bring it back?
View 1 RepliesYesterday I added a new user control to a project I was working on: right click on the project name "Estimator", then add, then new item, then on the add new item dialog I typed the name of the user control, and I created my ButtonWithCheck.vb control.
My user control appeared on the toolbox, I inserted it in a form, used it, kept working on my project, and everything was fine. I saved and closed the solution.
Today I open the solution and I got an error: "Could not find type 'Estimator.ButtonWithCheck'. Please make sure..."
Why a project saved while working doesn't load?
In the project I'm working on, I was editing a class and when I got done, I clicked save all. I moved on to my main form's designer. When it came up, the custom tab control I have on the form was blank. There used to be a ton of controls in it, so I am extremely confused about where everything went.I checked the properties window and it thinks everything is still there:ut when I check the Document Outline window, everything is gone. The tab control is still there, "AVERT Wizard", but all of it's child controls and tab pages are gone.

View 3 RepliesI have been learning and developing a software using VB for my company. I seem to have some issues with Chart function. [Code] Those 2 points will plot 2 datas (xval, finvall) & (xval, finvall2). Here is the thing. When I do the plotting, the starting points are always at (0, 0). That points come from the data point collector editor in the series properties. The question is: How do I plot data using the first value that I have? I don't want to start at (0, 0) but instead using (xval, finvall) & (xval, finvall2). I can't change the data point at run time. Many thanks!
View 6 RepliesI'm looking for advice to make my code efficient in terms of execution speed and memory usage. Basically, how to lay out my objects. The program displays parts of several data series in bar- or line- charts, as well as calculated series based on these data series. The key user input will be to change what part of data series to look at, and that input should trigger instant chart update, with minimal lag.

2.0 Framework.Our software does some measurement and then sends the output to our charting program. Right now it is taking 20-30 seconds for the results to print after our chart has sent the data to the printer since the printer is in sleep mode. What we are wanting to do is send a command to wake the printer at the end of our test, before it sends the results to the charting program, so the printer is (hopefully) done "waking up" by the time the chart program auto prints.
I have been looking around and haven't been able to find anything regarding this. The printer we are mainly using is a Brother HL 5250DN. I have contacted Brother but I have yet to hear anything back from them.
I have data that are numbers both on x and y and have charted them using mschart 4.0
I need to add a trend line/linear regression to a bunch of points I have. The data on x and y are both numbers (no dates anywhere), for instance (33.4,45.1) would be a point.
In the samples I downloaded from the first link I found a linear regression sample in the code files forecasting.aspx(.cs), and I found this ms documentation
I have added a linear regression line to the chart with the following line (once all other data it setup etc)
Chart1.DataManipulator.FinancialFormula(FinancialFormula.Forecasting, parameters, "Input:Y", "Forecasting:Y,Range:Y,Range:Y2");
The problem with both of these is that they assume dates are used. I went ahead and implemented it anyway, but my regression line starts at around the x value of 20, and will go to an x value of the max x value of one of the points (almost 70) if I give the parameter Period a value of 700. But since it doesn't start at x value 0 I don't trust it is correct.
Possible Duplicate: How to find web hosting that meets my requirements?
I was going to use the asp.net charting with Visual Studios 2008 but GoDaddy hosting does not support the charting cause they won't install the component.So what are my options for charting/graphs for data? Looking for free if possible.
I'm importing some data from MySQL into a VB.NET application with .NET charts. At the moment, the chart is plotting points by date, which means that when you zoom in, each major tick mark simply displays the date.It would be better to change these dates to times (hours) when one zooms in.Presumably there's a parameter to do this, but I can't find it.

But all the controls are still there, somewhere, because if I click the dropdown at the top of the properties window, I still see all my controls, and my code does not have errors. It was working fine 10 minutes ago!!

However - if i press the play button then i appears again but dissapears again when i close the form after playing it.
I don't know what happened I compiled the program and everything just disappeared from my main form....i can't name buttons the same thing that i recently had before everything disappeared so i know it still has to be there somewhere, i just don't know what to do.
View 8 RepliesI have a vb.net application, it is so far so good in high resolution. When I set the screen resolution of the machine to | 800 x 600, the header of the Save button has disappeared. If you look at the attached file, that means caption "F12" disappeared. I tested it in different machines, sometimes it is there but it may not be there in other machine.
I don't know whether it is the code error or machine environment setting up.

I've just started using Visual Basic - I'm completely new to programming altogether and thought it might be a useful skill - and I've been slowly working my way through the tutorials - from 'Learn VB' in the Start Page - and now the MsgBox function has disappeared! I have no idea why, as I'm doing the same thing (I think) as I was always doing. New Project > Windows Forms Application > Right Click on 'Form 1' in the solutions box > Source Code. Anyhow; when I type MsgBox there is neither a dropdown box with that name (IDE I think it's called?) and it becomes underlined with a squiggly blue line. I seem to remember that, in the IDE box, there were several different types of logos next to each name, but now only the logo that shows a windows with what looks like green highlighter written on it (you can see it if you type in #If) appears. I've already restarted the computer (via the start menu).
ps. I'm Running 'Visual Basic Express 2008' - and downloaded that yesterday (23/11/09)

View 3 RepliesI have been using a tabcontrol with multiple tabpages. On one particular tabpage I accept a value into a textbox which has worked many times. For some reason the textbox has now disappeared {clumsy thumbs are always a possibility}. However, when I try to put a new textbox in its place I find the textbox name already exists. I look for the name in the components address box in the properties sections of the ide and it doesn't exist?
View 3 RepliesI created a Windows Forms Application and spent a lot of time putting it together. This is my first project like it, it works correctly and... I'm very happy with it. However, I didn't open Visual Studio for a couple weeks. And when I went back to open the project's .sln file to edit it again, I can no longer see the design view with the layout of the program and all its objects (textboxes, labels, buttons, etc).
When I open a brand new Windows Forms Application, I can Right click the Form1.vb file in the Solution Explorer and "View Designer." Here is a picture. Now, when I right click on the .vb file from my program, that option is not there. As you can see, my program has a lot of objects. So I'm getting a concerned that I did something wrong and will not be able to use the design mode any more.
We have this custom DateTimePicker in our project where you can alter the BackColor and so on. But normally, when you click on the month of a DateTimePicker, it gets highlighted and you can change it with for example the arrow buttons on your keyboard or by typing a different number. Now the problem is that in our DateTimePicker, the highlighting doesn't happen anymore. When you click on for example month, you'll be able to change month but you don't see wether you selected month or something else.
This is the code we have (it's old code from way before I even started working here):
Public Class ucBaseDateTimePicker
Inherits System.Windows.Forms.DateTimePicker
' true, when no date shall be displayed (empty DateTimePicker)
