IDE :: How To Deal With Cells Excel Cells That Update Info Via The Web

Jul 5, 2009

My main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,

Number Formatting In DataGridView Cells?

Feb 28, 2012

I have a DataGridView that is showing some weird numerical data. For example, my under lying datatable of the datagridview has 4.69, but the datagridview shows 4.6899999999999999995. What is weird is it doesn't do it for every cell in the column. For example, my underlying datatable has 2.66 and the datagridview cell shows 2.66, which is correct. I should note that the underlying datatable column that contains the numbers is of floating point data type which comes from the database column and the datagridview column is TextBox. Here is what the values look like in the database, underlying datatable and datagridview.

Excel Worksheet Interaction With VB?

Apr 15, 2008

I would like to prompt the user, in the middle of a VB program, either with MsgBox or any other dialog, to input data in a worksheet of the Workbook that contains the code and then, on some event, read the data and continue execution. I was not successful with MsgBox (and other forms) since it is modal. The user cannot get focus on the worksheet, input data and then continue execution by clicking a command button.

Getting Incorrect Excel Worksheet Names In .net?

Jun 1, 2009

My application searches for a specific worksheet in an open workbook. The code to find the worksheet is:

If Amendaction = True Then
If oBook IsNot Nothing Then

For Each ws As Excel.Worksheet In oBook.Sheets

If ws.Name = SheetToFetch Then
SheetFind = ws.Name

[code]....

When I execute the code, depending on the worksheet name, the result found in ws.name has one or more spaces in front of the text. e.g. "Bour001" used in creating the worksheet name becomes " Bour001" when returned by ws.name.

Import An Excel WorkSheet Into A Datatable?

May 13, 2010

I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.

I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db.

.net - Excel Worksheet In Windows Form Application Without Opening Excel Application?

Nov 18, 2011

I am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.

I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:

{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
