I have a DLL that is written in C++. the functions of the DLL have parameters defined as unsigned char:
apiStatus __declspec(dllexport) __stdcall Gen2Read(HANDLE
hCom,unsigned char Membank,unsigned char WordPtr,unsigned char WordCnt, unsigned char *value, unsigned char ReaderAddr );
I have tried
<DllImport("Mr915ApiV10.dll", CharSet:=CharSet.Auto)> _
Public Function Gen2Read(ByVal hComHandle As IntPtr, ByVal Membank As Byte, ByVal WordPtr As Byte, ByVal WordCnt As Byte, ByRef value As IntPtr, ByVal ReaderAddr As Byte) As Integer
End Function
And the call:
Gen2Read(hComHandle, membank, wordptr, wordcnt, value, m_ReaderAddres)
In the original code in c + + value is: unsigned char buf [40]. And I'm not able to convert the value returned by reference into Byte ().

I have a radio button control on a web form. The members of my ListItem collection are
assigned the following.
Text No
Value 0
Text Yes
Value 1
So what I need to do, is to readd a varchar value from my database and if the column value returned equals 'Yes' then I need to select the radio button that has the assigned value of 1. Otherwise if the value read from the database is 'No', then I need to select the radio button assigned a value of 0
So how can I set the value for my radio button? I experimented and could not figure it out. The 'Yes' or 'No' value is stored in my database in the field ds.Tables("employee").Rows(0).Item("answer")
So I tried something like this which is not correct:
RadioButtonList1.Items.FindByValue(ds.Tables("employee").Rows(0).Item("answer") = "Yes").Equals(True)

how to add a string item to a text box, returned from another form that has a list box?

passed to the first form that will also have a text box. The text box should contain the value of
list box.

Private Function base64Decode(ByVal strEncoded As String) As String

I don't think the web server is trying to encode anything as there are no + symbols within the url string and I have just glanced over the two to compair they are the same.This returns a blank string whereas when I use the sections commented out in the first loop i get a really weired string back and when I use their simpleXor function it just returns complete nonsense.

there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

Currently, I'm using the following code to pull info from the management class.
[code]...
I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.

I'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.
The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.
The way I originally intended to do this was like this:
If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If
The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.
A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.

Value of type 'System.Func(Of String, String)' cannot be converted to 'System.Converter(Of String, String)
Why? They are both effectively a function pointer (or delegate?) to a function that accept a string and return a string.
