I think the best way forward is pass a parameter to the function findnumber.
I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

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. Help...

View 5 RepliesWhat will be the fastest / most efficient way to copy the contents of a byte array into a string?
View 3 Repliesunfortunately I cannot resort to C# in my current project, so I'll have to solve this without the unsafe keyword.I've got a bitmap, and I need to access the pixels and channel values directly. I'd like to go beyond Marshal.ReadByte() and Marshal.WriteByte() (and definitely beyond GetPixel and SetPixel).Is there a way to put all the pixel data of the bitmap into a Byte array that works on both 32 and 64 bit systems? I want the exact same layout as the original bitmap, so the padding for each row (if it exists) also needs to be included.Marshal doesn't seem to have something akin to:
byte[] ReadBytes(IntPtr start, int offset, int count)
