View 8 RepliesConvert Byte Array To Boolean Array?
Nov 4, 2010The following image or RTF file illustrates how I'm trying to transform an input Byte array into an output array of Booleans. This is basically what I have listed below. figure out how to get from one array to the next while shifting values of bytes within 8 byte groupings to shift low order to high order or vica versa. What I mean by that is best seen by looking at the illustration of actual input an required output. The reason for this is that the hardware devices have registers and the display which can be seen in the links above needs to convey the disabled sensor cable cell locations.

Converting 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]
Reading Named Range Into Array - Constant Expression Required
Mar 11, 2011I need to read a named range into an array. Then if the value in the 1st position matches a static value, read the value in the second position. I've been looking into array's and this is what I think will work, however I get a compile error on the columns.count "constant expression required". Is it because in the DIM statement I'm attempting 2 things? This is a macro in Excel. The range name is Data1 and the string comparison is "AnyString". The second value will be an integer.
Sub macro1()
Dim rng As Range
Dim x As Integer
Dim y As Integer
rng = Range(Data1)

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.
.net - Interop Cannot Call Get_Range, And Cannot Use Two-dimensional Object Array Returned By Range().Value2?
Jun 1, 2011Trying to replace Cells(RowIndex,ColumnIndex).Value() calls by row-wise references for performance, I permanently fail at referencing the result. Starting with Excel Interop - Efficiency and performance, which contains the tip to use get_range, i.e.
//get values
object[,] objectArray = shtName.get_Range("A1:Z100").Value2;
iFace = Convert.ToInt32(objectArray[1,1]);
//set values
object[,] objectArray = new object[3,1] {{"A"}{"B"}{"C"}};
rngName.Value2 = objectArray;
[Code]...
However, referencing Values with two dimension indices always returns an "index was outside the bounds of the array" exception. Inspecting the array with the debugger shows a nice 2-dimensional array which should has 17 elements on the second dimension, so Value (0,0) should indeed be a valid reference -- but it isn't:
The debugger lets me inspect Value, I can also drill down to Value(0,0) and see the correct value, but re-evaluating just that element, i.e. inspecting "Value (0,0)" returns above message.

VS 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?
