Can't Assign A Different Address To Such A Variabl
Jun 18, 2008
At the moment, we can only declare parameters 'ByRef' and we can't assign a different address to such a variable. Why don't we have local variables that are declared 'ByRef' and an operator to assign a new address to such a variable? (And maybe even use functions that return pointers??)I know you're going to tell me that VB doesn't support pointers, but the fact is that they do exist and isn't it a bit silly to say 'We don't support this because it looks a bit like unsafe code even though it's not'!! And for anyone who says that it complicates things, well, don't use these variables.

Admin assigns the authority and get a new form to the new assign in with vb.net & access. I am not sure about this,I need a way to do the new form assigned? How?Actually, this project is the admin will assign the authority to a manager, and the manager will get the password to log in. Then, the manager once log in and will get a form to set the rooms who is going to use and date, etc, this is multi-manager to handle the room setting jobs.But, I think, I got stuck, I am not sure how to do the new form, HOW DO YOU ASSIGN THIS NEW FORM FOR EACH NEW MANAGER?????? THIS IS VB.NET WITH ACCESS.

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

Consider following code:
Dim S1 As String = "a"
'this is the string in a file
Dim StringFromFile As String = "S1=hello"
[code]....
how to assign value to S1?I have declared a string named S1. Now I want to assign new value to S1. The new string value is stored in a file using following format: [variable name][= as separator][string value]. How do I assign the value to S1 after retrieving the string variable name and value that stored in a file?
NOTE:
temp(0) = "S1"
temp(1) = "hello"
It should be noted that the string with the data comes from a file that may change from time to time! When the file changes, I want the variables to change as well.
Further clarification I need a piece of code that when processing a string like this "S1=hello", the code will first find a declared variable (i.e. S1), and then assign the S1 variable with "hello" string. The "=" just acted as separator for variable name and variable value.
UPDATE:
My attempt to use Mathias Lykkegaard Lorenzen's EDIT 2 example but failed with "NullReferenceException" on this line "Field.SetValue(Me, VariableValue)". Please help me fix the problem. Following is my code based on Mathias Lykkegaard Lorenzen's EDIT 2 example:
Public Sub Ask()
Try
Dim S1 As String = "a"
Dim StringFromFile As String = "S1=hello"

Does Visual Basic arrays have the possibility to assign values in one line?i.e. No need to have a loop to assign a value for the whole array.for example,
Dim Array1 (1000) As Integer = 478
Dim Array2 (1000, 1000) As Integer = 852
this means that all values of array1 will be 478 and the other is 852.

I've been making this BlackJack program for a school project
I have 52 image files, labelled from '_1' to '_52' in my resources folder, each number corresponds to a card.
My question is, how do I get a picture box to assign the correct resource according to a variable
So, say I have
"pictDealerCard1" -> picture box which displays the first of the dealers card
DealerCard1 = 37 -> random number generated through INT(RND() * 52)
and resource '_37'

I have an application in VB.Net that displays the results of a math operation to a listbox. For example I have the 12345 + 12345 = 24690. What I'm trying to do is to have the first 2 numbers (12345 and 12345) copied to 2 different textboxes when listbox item is selected. Here's the code I have so far:
'Make sure that we have a selected item before continuing
If listBox1.SelectedIndex = -1 Then
Return
[Code]....
During runtime it only works with index 1 when it gets selected. I have 10 records being displayed (0 to 9). None of other indexes are being shown at the textboxes.

I am experiencing aproblem in my VB.NET App. The salary form is a databound form in my app to a linq data source. There are several text boxes to enter and calculate different salary fields. e.g. Basic Salary, Budgetary Allowance and Adjusted Basic Salary...
all the above three controls are bound to the datasource. now on the Leave events of the Basic Salary and Budgetary Allowance there is a function to calculate Adjusted basic salary.
The problem is i dont see the calculated amount in the adjusted basic salary but i see only the underlying data in the database instead of the programmatically calculated amount.
