I'm using vb.net 2008 edition and i was wondering if there a way to convert an array type to another array type. For instance say i dim an array as string and then want to convert the array to the integer data type for sorting, how would i go about this?
View 1 Replieswrote a procedure that accepts as input a parameter of type decimal, or type Long as well as an array type ar() as Boolean. First thing I will do in the procedure is establish just what type of parameter I received. No problem with the scalar types, I'll use the .GetType,determine whether it's Long of Decimal, and assign the parameter I just received to a variable of that type by using convert.toInt64 or convert.toDecimal, then do what I need to do. Not so if the parameter I received happens to be an array. .GetType will tell me what it is, for example returns "system.int64[]" if its an array of Longs, but then I fail to assign it to a variable for further processing as there appears to be no conversion method to do that.

In order to re-sort the data received in USB easier, I send the data array received in USB (declared as Byte) to a temporary array (declared as SByte) to re-sort. I declared the temporary array as SByte just for easy sorting. After I compiled, an error message came up "make sure not divided by zero". I tried to use convert.SByte but still didn't help. Is it not allowed to send data to an array with different data type declaration?

I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format. I mean user can retrieve value in any numeric array type rather than specifying an array type. E.g.

View 6 RepliesI've inherited a tested function that processes incoming data from a .NET Serial Port. (Dim RXBuffer as string = serialport1.ReadExisting) I've written a different part of the application that processes a byte array as received from an asynchronous .NET socket.
Is there a way I can convert the byte array into a string as if it arrived from the serial port?
I would prefer to rewrite a very long 'if statement' into byte array functions syntax that look like:
dim b as boolean = IsBitSet(state_buffer(i), j) 'rather than:
dim b as boolean = (Asc(Mid(RXPacket.Pdu, CInt((i - (i Mod 8)) / 8) + 1, 1)) And CInt(2 ^ (i Mod 8))) > 0

View 8 RepliesThe 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.
