I have returned object from signature device and when i make quick watch on it, it told me that its an array of long and when i pass it to web method in my code behind (vb.net) it gives me nothing. note: i'm using an activeX to capture the signature from the device.
this is javascript code :
function OnSave() {
var sign = document.FORM1.SigPlus1.SignatureString;
PageMethods.Save(sign);
}
this is my webmethod:
<WebMethod()> _
Public Shared Function Save(ByVal obj As Object) As String
Dim obj1 As New PFSIGNATURELib.SigniShellSignature

I am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.
Shared Function CompareArray(ByVal FirstArray() As Object, ByVal SecondArray() As Object, Optional ByRef ErrorMessage As String = "") As Boolean Dim IntArrayOne() As Integer = {1,2,3,4,5} Dim IntArrayTwo() As Integer = {1,2,3,5,6} Dim IsSame As Boolean = False IsSame = CompareArray(IntArrayOne(), IntArrayTwo())
Most of the time when we read the file stream into a byte array, we would write the following code.[code]But here we have to convert Length into an integer type (line 2 of the code above) since we cannot declare a byte array using the long data type (with option strict on). Is this a good practice? What is the work around for this problem?

i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this stupid question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net

I'm currently trying to write a football simulator but am having issues with the computer becoming unresponsive. There are long lines of code (several thousand lines) that are executed over and over as one run of the code is equivalent to one second of game time. While the game is setup to be like Football Manager where you watch the game live, there will also be cases where the entire game is simulated without you watching. When doing a full sim of a game, I just have a loop which executes the code block 7200 times (games go for two hour roughly).
At the moment this takes about a minute but even when I get it down to the desired 5-10 seconds or so, I dislike the fact that the computer becomes completely unresponsive during this time. In a round there are 9 games and you'll be simulating without watching 8 of them. You're looking at 1-2 minutes of simulation time or possibly more. I can't have a loading screen that long! How can I program the game so it runs these simulations yet the game still remains responsive? It'd be fine if the user could muck around in the menus and stuff while the simulation runs.
Is there a easer way of coding in stead of wrighting long long paragraphs like this in one line [code]All of this is on one line and i got lots of info to put down.."The game will begin on your 16th birthday with your mother waking you up. Today you are to go to the castle for the first time. Leave your bed and open your dresser for a Strength Seed. "
I am trying to pass a 2D array into a dll I wrote in C. When I run the program, it crashes at the first line (in the dll) that I try to read the array. It gives an error that it is trying to read protected memory. I'm guessing this means the array was not correctly passed to the dll, so the program is trying to read a memory location that doesn't exist. Is the problem somewhere in my VB code? If not, it must be in my C code, right?
Here is my VB code:
Declaration of the function in the dll:
Code:
Private Declare Function image_processing Lib "image_processingDLL.dll" _ (ByRef image_array As Long, ByVal dpi As Long, _ ByVal xDim As Long, ByVal yDim As Long) As result Calling the function:
I am using Visual Basic .NET 2005 and I need to call a DLL made in VB6. Couple of days ago i wrote a test dll in VB6 and called it from VB.NET. I passed an array and another variable. And the dll got it and displayed the values in the array. (I didnt save that code)Now when I am writing it again I am getting an error "Specified array was not of the expected type." [code]If I do not pass array then it accepts but otherwise it does not. The array here is CD().
I have a site that dynamically creates two arrays of Lat/Long values based on the stores that the currently logged in user can see. If the user can only see one location then I get an error about array length needing to be a finite integer. When I look at the source I see var ls = new Array(45.056124);is being created on the page dynamically which is what I'm expecting. Except I think it is treating it as if I am trying to set the length of the array instead of set the first element to that value.How do I go about creating an array using the ClientScript.RegisterArray Declarationfunction to hold a single double value using vb.net?

I have "Form Designer" web application, in which I need to post the controls of the new form to an ASP.Net page to insert to DB, each time I create form control. I push it into two dimensional array, when user click save, this array will be serialized and sent to Server Page using Ajax.
I am trying to extract data stored in javascript array inside WebBrowser window. Basically I need to wait for scripts to execute (got that one covered) and then somehow get the array.
I have an old program written in VB6. I upgraded the program with VB 2008. The updated program works fine except when the program tries to transfer an array to another subroutine. The old VB6 program sends arr(0) as an argument to the subroutine, the address of arr(0) is passed to the subroutine. The array arr() address is the first of a block of consequent addresses one by one, arr(1), arr(2), etc.
Now when running VBnet, the address of arr(0) is not the first of all consequent arr(1), arr(2), etc. It is an isolated number, just like if arr(0) were a variable instead of an array. The addresses of arr(1), arr(2), etc do not exist in the subroutine. [Code]
The variable of y1 passes to the subroutine oK, whilst arr(0) passes also like y1 into an isolated address. So VBnet interprets arr(0) like a variable rather than the first value of a long list. I haven't been able to find out why the above sample does not work. I got stuck in my programming effort, as I cannot proceed to to further development. how the code should be modified to enable the whole array information passing through the subroutine.
I m a student and new to VBI m triyng to pass an array as parrametersAnd the compiler says I havent declared the array my coding is as below
[XCODE]Sub Main() 'Fill array Dim MyArray(0 To 9) AsString For lLoop AsInteger = 1 To UBound(MyArray) Console.Write("Enter First Name " & lLoop & ": ")
When I try to do the same in .net the "array argument" value of the second sub is either Nothing or I get an error saying "Value of type 'String' cannot be converted to'System.Array'."I've tried converting the array to a system.array but it will not hold all the Types of data it needs to hold. (I tried 3 days ago and don't remember what Types would cause an error. My 1st value is a string and the second is an integer and this caused some error.)
