Refresh Charts Displaying Dynamic External Data?
Nov 10, 2010
I have an array of data which is currently updating itself every 10seconds from when my spreadsheet is opened as you can see from the VBA module code given below, that is fine but the charts that I have created manually from the data are not updating themselves as the data changes. When I change the data by editing a number in the range etc. then surely enough the chart updates. Is there any code available which will refresh the chart I have made automatically say every 15 seconds, giving a 5 interval breathing space between the data and chart update?
The code I have attempted to resolve the problem in the Sub AllWorkbookCharts () doesn't work as there is a problem with the refresh part of it.
Sub Update_Time()
Application.OnTime Now() + TimeValue("00:00:10"), "Sort_Table"
Application.OnTime Now() + TimeValue("00:00:15"), "AllWorkbook_Charts"
End Sub
Sub Sort_Table()
[Code] .....

I am using VB for developing a GUI. I need to display charts in the VB form. How do I invoke Excel 2003 using VB and import the charts created in it.
Steps:
1) Getting input from the user using VB form and processing it in VB or external application such as Matlab.
2) Over-Write the processed data in excel sheet.
3) Modify the charts based on the new data which I believe will happen automatically.
4) Display the chart in the VB form.

We have an existing VB.net application. Upon an event, we need to open a browser window. I'm able to open the browser window like this:
System.Diagnostics.Process.Start("http://s3web01/suggestions?item=" + strItem + "&co=" + strOrder)
Upon another event, we need to refresh the browser window with different parameters for strItem and strOrder.
If I call the same code above, it opens a new tab in the browser window. Is there any way to refresh the same browser window that was previously opened?

I have a combo box and a property grid in a form. The combo box contains 2 items. If one item is selected, two properties are listed in the property grid. These properties should have a dropdown that contains a list of items. I have two string arrays that contain the values for these properties. Can I use one TypeConverter that inherits StringConverter for these lists to be displayed in two different properties? That is, with one TypeConverter class, can I populate both the lists? I will also have to do the same with the other items in the combobox.

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.

I am working with vb.net 2010 SQL express 2008 and ReportViewer. I have created a form that a user can add, edit and delete data which is all stored in an SQL db. I am printing out reports for the user with ReportViewer. The issue I am encountering now is that at runtime if I make any changes and decided to view the changes via a report with ReportViewer, the change will not reflect. I have to close the program and open it up again so that I can view the changes. What do I have to do in order to view the changes view ReportViewer during runtime? This is my code:

I have a ReportViewer showing a report that is bound to a dataset. The dataset gets its data from a Access database backend. I have a separate form that allows the user to add/update/delete data. My problem is when the user makes changes to the data using the data entry form, the report does not reflect those changes. I have to close the entire program and reopen it before the changes take effect on my report.[code]...

On my Winforms app, I have a primary form with a DataGridView bound to a database Entity datasource.
The grid is set up not to allow inserts. Instead I have a button on my form that kicks of a second dialog where the insert takes place (ie. with friendlier ui than is possible with the DataGridView).
The insert is working fine.. query of the underlying table in db shows that the record has been inserted. However, I can't seem to get the DataGridView on the primary form to see the new data just created by the second dialog.
I have read many Stack Overflow q & a's and tried various solutions to get the DataGridView to refresh to show new data.. but nothing works.
This must be a common situation ?? Can someone suggest some VB.NET code that will work ?
