I am develping an application that integrates with an RFID kit. The problem is, the kit comes with an .cs class that accepts data stored in a byte array however, each information stored in the array respresents an int. I wanted to store String information in each array but, my research suggest that a String itself can be converted to a byte array and not a byte....here the code from the .cs class:
byte BlockNo = 0;
byte[] BlockData = new byte[16];
byte ReturnCode = 0;
[code]....
Each t_b*.text respresents an int. Is there a way I can stored a String in a single byte block?

View 7 RepliesHow do you store multi-dimensional array to viewstate? Here's what I did:
public bool[,,] regsettings = new bool[7,5,4];
bool[,,] regsettings = (bool[,,])ViewState["regsettings"]; // this line works!
regsettings[i,j,tab] = (bool)ViewState["regsettings"]; // this line no working?! The error is: Object reference not set to an instance of an object. The letters i,j, tab are just variables in the loop. They are there. I also tried: (bool[,,,]) as a cast and it is a no-go either.?

When I run the program, an error occurs:
Unable to cast object of type 'System.Collections.Generic.List`1[System.Int32]' to type System.Int32[]'.
Why does this error occur?
I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
I want to pass the Array ( object[]) or Structure data type value to the store procedure through
