Array In From A Range In Excel?
May 31, 2010OK I have been gooding for over 8 hours trying to figure this out. Bare with me I do not work with arrays much.I have brought an array in from a range in excel. This works fine. Through debugging i can see the values are brought in correctly.
Issue is I want to see if a string exists within that array (or cells).I have tried lots of things and pretty much mutilated my code but here it is:

Office Automation :: Excel Range Into A .NET Array?
Jan 10, 2011I 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 RepliesVS 2008 - Array - Error Report Shows An Event Type Of Clr203r And An Index Out Of Range Exception
Aug 12, 2011I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?
Iterate Though Range Of IP Addresses
Feb 7, 2012I need an elegant way using VB.Net to iterate through a range of IP addresses when the input will come to my app as a string in this format: 192.168.100.8-10 This range would include 3 addresses: 192.168.100.8, 192.168.100.9, 192.168.100.10. I found a solution in C# that uses the IP Address class that I could probably convert to VB but it seemed to be way too much code for what I need to do. I could definitely use a bunch of string parsing functions but I was hoping someone already had a simple way of doing this.
View 1 RepliesConverting From VB6 - Reading Excel Range Into Variant Array
Oct 18, 2011In 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?

View 3 RepliesEfficiently Assign Cell Properties From An Excel Range To An Array
Jul 26, 2010In 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]
Office Automation :: FindAll Matching Strings In Excel Range / Array?
Feb 12, 2012I 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.
VS 2008 Array.BinarySearch Or Iterate?
Nov 10, 2010So I discovered the .net array class has a built-in binarysearch method. Do I want to use this all the time (that is, when I meet the prerequisite that the array is sorted) or are there times when I would want to just iterate through the elements starting at 0 and incrementing until I find what I'm looking for? Is there an optimal size that recommends using one way or the other?

Excel To Powerpoint Macro - Copying Excel Range And Pasting As HTML Or Default In Powerpoint?
May 11, 2011I'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).
