Excel 2010 Value Property For VS 2005
Feb 24, 2011
I'm recreating a program (don't ask - it is embarrassing) in Visual Studio 2005 VB where I read a spreadsheet in an then select values from certian rows. I added the Interop reference and the MS Excel 14 object library, but when I type something like:
Public oSheet as Worksheet
...
x=oSheet.Cells(Row,1).Value.ToString
I'm concerned because when I type the period after the ) it does not allow me to select value. I type it in and it does not give an immediate syntax error but I'm guessing that when I try to run this, it will fail the build. Is there an other reference I need to add or do you get the value of a field differently for Office 2010 than we did for Office 2007?

I am using the code below to export records in a datatable to an excel file using EPPlus.
Dim excelPackage = New ExcelPackage
Dim excelWorksheet = excelPackage.Workbook.Worksheets.Add("DemoPage")
excelWorksheet.Cells("A1").LoadFromDataTable(dt, True)[code]....
However, after walking through the code block, at Response.End(), I get an exception {Property evaluation failed.}
Update:
The error log is:

I am trying to use a spreadsheet with VBA macros that I wrote in Excel 2007 in Excel 2010.When the macros run in 2010, I get the error message "Can't find project or library" on functions like UCase and Date.I've set the macro settings to "Enable all macros" and selected "Trust access to the VBA project object model."What do I need to do to get these macros to run in 2010?

Error: System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC is thrown after execeution of Microsoft.Office.Interop.Excel.ApplicationClass.set_Calculation(XlCalc ulation RHS)
Out of nowhere COM start throwing exception when I set change excel's Calculation property. Line of code that followed set_Calculation was.Workbooks._Open. This used to cause exception every second try. Than I changed order, first open workbook and than set calculation property. Amount of exceptions start decreasing than I added thread.sleep(200) and exception is not thrown anymore. This happens only on one some of user machines while others are fine.Application itself is single threaded so this delay should be of importance if and only if set_Calculation is executed asynchronously. What I'm missing here?

I've automated quite a bit with excel and every so often one of these really annoying glitches pops up.I'm using Office 2003, all with latest service packs and everything, and basically I usually end up creating a lot of applications which automate excel, processing database information and exporting it etc, etc, etc.
I currently have finalized this most recent export process, which exports a moderately sized table into excel for the user to work with, but I wanted to adjust the printing area appropriately.SO, I set the PrintArea to the A1:K47 string, I set the FittoPagesTall/Wide to 1 and the Orientation to Landscape, and all of this is perfectly functional from my 2008 .Net 3.5 application. But in the open application window of the file i'm automatically creating, the page divider lines still show 4 pages of data. Now, I said to myself, i know that in the Page Setup Dialog I can set "Fit to Page" and it automatically adjusts the zoom factor (scaling) to fit the print area onto 1x1 pages.
The only property in the WorkSheet.PageSetup that appears to do this is the ChartSize property, but when I step over that line in the Application I'm debugging, I get the Exception:"Unable to set the ChartSize property of the PageSetup class"Now the only thing i've seen online about this error from Microsoft says it could occur when a printer isn't installed. That is not the case here.
I further looked up in the property and it said something about only being applied to "Chart Sheets" but when I try to use the workbook.worksheets.add() method witht the Type set to xlChart I get a com object disconnected from RCW error.NOw, I can manually go into the Page Setup Properties for the Excel Worksheet, and set the "FIt to Page" there, so How can I forcibly automate this exact same process without having to open the Excel APplicaiton.

I need to import a .csv file so that it formats it all nice-nice so I can easily get the information from a column or row, then I need to grab certain rows, then reorganize it and save it into a different Excel spreadsheet for the program to then use. The original .csv does not contain the information in a way that we need it to be.
What I found so far: I saw this code snippet online
'-----------------------------------------------------------------------
' CONVERT CSV FILE TO XLS AND PROCESS XLS ROWS AND COLUMNS
' Opens Excel, imports .cvs file into xls format
' Iterates xRows and xCols from xls format

I am using the following code to load a file into my program, everything works fine. When I open a new file everything works fine unless I have this line inserted:
Me.BindingSource4.Sort= "NewDateSold Desc"
That line works unless I open a new file while in the same instance of the program running. The I receive the following error:
Sort string contains a property that is not in the IBindingList.

There is no BackStyle property in Visual Basic 2005 ... But I read in MSDN that changing the BackColor of label control will make the background of label control Transparent ... So we'll be able to see through the label control ... I changed the BackColor property to Transparent but it didn't work for me ... BackColor changed to Transparent ... But still I ain't able to see the image behind the label control ... (PictureBox) ... Background color of label still remained the background color of Form i.e. Control color ...

some controls(e.g. buttons/labels) dont have a drawmode property. Im looking to create buttons with rounded corners because they just look nicer :P. Now, the problem is that even when you have a custom paint event, the button just gets drawn first and the custom paint event will draw on top. Especially with rounded corners, where you see the parts of the default button in the corners. Is there a way to only execute the custom paint event / block the default paint?

In the application I'm documenting, sometimes a value is stored in a Public variable & other times it's passed to/from a Public Property which does nothing except store it in/retrieve it from a Private variable. (And in one memorable exception, the Public Property stored it in a Public variable-I'm almost certain that was an oversight by the original programmer though.)
I know that passing it to/from the Public Property has the potential for better validation, but if the Property doesn't actually do anything except store/retrieve it is there any benefit to declaring it as a Property? (Or maybe I should put that the other way around. Personally I'd declare them all as properties because that will allow adding validation later-but I'm not rewriting this, I'm just trying to document it and, in this case, trying to figure out why sometimes it's done as a property & sometimes as a Public variable.)

If you assign a ContextMenuStrip to the DataGridView.ContextMenuStrip property and then right-click a cell, the CellMouseClick event doesn't fire. Why would the ContextMenuStrip block this event from occurring?
My workaround at the moment is to separate the ContextMenuStrip from the DataGridView and show it with code, but this seems unnecessary.

I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)
[Code]...
I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!
