Efficiently Assign Cell Properties From An Excel Range To An Array

Jul 26, 2010

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]

Converting From VB6 - Reading Excel Range Into Variant Array

Oct 18, 2011

In 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?

Office Automation :: FindAll Matching Strings In Excel Range / Array?

Feb 12, 2012

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.

DateTime - Cannot Assign Properties Value From Database

Jul 27, 2011

I need to have a property that is a nullable date as the datestamp is used for when a process is completed. If there is no date this is a way to determine if the process has occurred. I have created a Nuallable DateTime property (DateTime?) However when I try to assign a value from my database entity (when debugged has a date value) I am not thrown an exception however my property still reads a null value after assignment. How can I get a DateTime? type to accept a DateTime value?

I thought this would do the trick
_object.DateStamp (type = DateTime?) =
_entity.DateStamp (Type = DateTime?, Value = DateTime) o
Or for more understandable syntax
Ctype(object.DateStamp, DateTime?) = Ctype(entity.DateStamp, DateTime?)

Strange thing is I can assign the properties value like this.
Ctype(object.DateStamp, DateTime?) = Now
I am using LinQ Entities.

C# - -copy A Formatted Cell In Excel To A Table Cell In Word Using .NET?

Apr 20, 2010

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

Excel To Powerpoint Macro - Copying Excel Range And Pasting As HTML Or Default In Powerpoint?

I'm trying to copy a Range from Excel and Paste the information in powerpoint in either the HTML or the default format, however, I am having some difficulties. I am able to get the code to work for pasting the Range as an OLE Object but nothing else. The problem with doing this is that having the embedded excel documents in the powerpoint makes the file extremely large and unstable. I just need to be able to paste the information without the embedded information where it is editable (so, not as a bitmap or picture).
