I am trying to open an exisiting excel sheet and then I want to copy a range of cells in to an array in one shot instead of looping thru cell by cell.And then I want to do some calculations and then move them to database tables.[code]...

I am currently using Outlook 2007 and Excel 2002 SP3 and VBA for OfficeUsing VBA, I want to copy a range from Excel, open a new email in Outlook and then past the range into the body of the email (rather than as an attachment) as a Bitmap (so that the report on the email looks exactly the same a the range that is copied from).I can do most of the above but putting the bitmap into the body of the email is neigh on impossible..I can get VBA to paste the range into an email but then it loses most of its fomatting and looks horrible. Thats why I'd rather put the bitmap into the body of the email.I'm guessing that there is no easy solution to this..

I have formulas in certain cells and happens to be part of the Excel range that I pull into a vb.net array and when I write the array back out to the Excel Range, I loose all the formulas in it.Is there an option to retain formulas in a .net array?
View 3 RepliesIn VB6 I could assign an Excel range directly to a variant array dim vArr as variant vArr = xlSheet.range("A2:A10").value and then work with vArr to pull out the values I needed. This doesn't work in VB 2010. Is there a replacement procedure to allow me to read in a range (perhaps large) all at once and then process the data without needing Excel?

In VBA / VB.NET you can assign Excel range values to an array for faster access / manipulation. Is there a way to efficiently assign other cell properties (e.g., top, left, width, height) to an array? I.e., I'd like to do something like: Dim cellTops As Variant : cellTops = Application.ActiveSheet.UsedRange.Top..The code is part of a routine to programmatically check whether an image overlaps cells that are used in a workbook. My current method of iterating over the cells in the UsedRange is slow since it requires repeatedly polling for the top / left / width / height of the cells.I'm going to go ahead an accept Doug's answer as it does indeed work faster than naive iteration. In the end, I found that a non-naive iteration works faster for my purposes of detecting controls that overlap content-filled cells. The steps are basically:
(1) Find the interesting set of rows in the used range by looking at the tops and heights of the first cell in each row (my understanding is that all the cells in the row must have the same top and height, but not left and width)
(2) Iterate over the cells in the interesting rows and perform overlap detection using only the left and right positions of the cells.[code]
I am importing data from an Excel spreadsheet into an array. I want to search the array to find the location of each "cell" with text that contains a certain string (e.g. "MyTestString"). So far the best I can do is loop through each element and test it using CStr, but the code takes too long to execute (please assume all variables are properly declared):
[Code]...
(1) Is there a better way than looping through each element, such as a built-in function or a lambda that will return an array containing *the location of* all string matches?
(2) Would it be faster to convert the Object array to a String array rather than using CStr on each element? If so, what is the fastest way to convert a 2-dimensional Object array to a String array?
I've considered using Excel's Find function instead, but would prefer to limit the number of Interop calls to Excel.
I need to import data from Excel worksheet into the VB.Net program. First, I need to get the data to some array or arraylist and secondly to show the data to user through datagridview or similar.So far, I have this

Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=C:TempTest.xls ;" & "Extended Properties=Excel 8.0;"[code].....
How can I adjust the code to manage that? And how can I import the same range to variables (the range contains approx. 200 rows and 30 columns of data points) and I need the flexibility to add or delete items (rows) from the data in memory later.
I have successfully constructed several one-dimensional arrays and correctly passed them to an output subroutine. I am trying to pass/copy the values of each array to an Excel spreadsheet, but have encountered 2 problems.
Problem 1: The program fails on the following line: outSheet1.Range("B2").Resize(passFile1IndMax + 1).Value = passFile1Amount with the error message: "Value does not fall within the expected range"
Problem 2: When commenting out this line (and the corresponding one for passFile2Amount), the program no longer fails, however, the results show 8 rows (passFile1IndMax and passFile2IndMax both = 7) of the same data (e.g., A2:A9 all = 3/1/2011 = passFile1Date(0))--the first item in each array.I am trying to avoid looping through each index value and assigning values on a cellby-cell basis.

This should be very simple but I'm very new to Visual Studio so I can't get it to work. I want to take data from an excel (2003) file and turn it into a bunch of charts that would be viewable on a webpage that I'm trying to build in Visual Studio .Net 2005 professional.
I can't seem to use an excel file as my data source, here are the steps that I've followed:
1) created a new asp.net project
2) dragged a report viewer from the toolbox and it asks me to choose a report or "Design New Report."
3) Clicked Design New Report, and it opened up a new blank report.
4) Clicked "Add New Data Source" and got the Table Adapter Configuration Wizard.
5) Clicked new connection and it brought up the Add connection table.
6) Clicked "change" under data source and I chose Microsoft ODBC Data Source (not sure if that's right.)
7) Under "Data source specification" I chose "Excel Files"
- The first time I did this it brought up a window for me to choose an excel file so I did. Something along the way failed out but it stilled saved "ConnectionString1" as a connection to that first excel file. Now every time after I choose "Excel Files" and click "OK" the add connection window disappears and it goes back to the Table Adapter Configuration Wizard with the "ConnectionString1" as the connection string. It won't let me specify any different excel file. So I did 1-6 again and picked up at 7B
7B) Instead of using "Use user or system data source name:" I chose "Use connection string:" and clicked Build.
8) Picked the "Machine Data Source" tab and chose "Excel Files" and clicked ok
9) The "Select Workbook" window appears so I went to the file I wanted to use as my data source and click OK
10) Back on the Add Connection window I clicked test connection and it succeeded so I clicked ok.
11) It goes back to the Table Adapter Config Wiz window, but the connection string only says "Dsn=Excel Files"
12) clicked Next, then Next again, then clicked on Query Builder. The Add Table window pops up but there is nothing in there for me to choose from.I've tried a million other things, here are a few of the errors that I seem to get a lot.

Part ot my program is to simple copy a range of cells ~21 000 rows from one WB (oSH) and copy it to another WB (oSHOut).I've red a lot of posts,tried a lot of variants, but nothing helps..Strange here is that if I copy less than 8500 rows, the paste to the destination range is OK.But if I copy the whole range ~21000 rows, vb.net trigers an error - "Copy method of Range class failed".So I tried to do this in several parts - 1 row to 8000, 8001 to 16000 ect.The first copy-paste works OK, on the secon - there's an error.[code]
View 5 RepliesI refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.
