Oct 14, 2011
i am currently looping through this with vb.net and writing on the console:

[code]....
however, i would like to store my values like this this:
array (
"fruits" => array (
"a" => "orange",
"b" => "banana",
[code]....
then when i get this, i would like to loop through each
array (
"fruit" => "orange",
"b" => "banana",
"c" => "apple"
)
and check for certain values.i can do this easily in php, however, vb.net leaves me?

I'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.

I am trying to read a comma delimited text file to an array, then change just one element in the array and write it back to the text file. An example of what the text file would look like is:
data1,data2,data3
data1,data2,data3
data1,data2,data3
I want to change data in the last line at the last postion , data3, for example. I am reading the file in with no problem. I am stuck on how to change the data and write it back to the text file.

I have a datagrid in my form and numbers are input it. I then loaded one of the columns into an array. This is the piece of my code that loads the array:
Me.dgv.CurrentCell = dgv(1, 0)
For i = 0 To (Me.dgv.RowCount - 1)
Receipts(i) = Convert.ToSingle(dgv(1, i).Value)
Next i
The first value is -2912895.29. I put the program in break-mode and it keeps loading the first value as -2912895.25. I checked and it loads all of the values a few cents off.

My app is receiving data in blocks but I don't know what size data will be received until it is finished, unlike file reading. So my app loads the data in chunks of 1024 bytes and then stops when there is no data to read. My question is, is it possible to keep increasing the size of a byte array as the data is being received?

So I have an array which holds instances of a structure. The structure contains various string properties.
I'm looking to modify each instance of a structure within this array by doing the following:
For Each stuInstance As StuInstance In arrStuInstances stuInstance.strCarName = "Benz"
But I found that this in fact fails to really change it permanently. If I do the following loops in the given order:For Each stuInstance As StuInstance In arrStuInstances

I've got a listbox in visual basic 2008 with lines that look like:
item 0; item 1; item 2; item 3
How can I select that line and change within that line the value of e.g. item 3? (by default it's set to 0 and should be set to a value > 0 when entered by the user.
After that I need to calculate the total price based on the price in item 2 and the new value of item 3 (being >0)

I have created 3 arrays of buttons for a form which manipulates the value in a combo box or 2 by the name of the button ( buttons named 2 through to about 70 )
This works great but the problem is, now that the buttons are in, I want to be able to change the color of the buttons when another button is clicked
ie. The first bunch of buttons is a list of locations all with unique text.the second bunch of buttons is events that happen, sign on, sign off, beach open and beach closed.
What i want to be able to do is change the color of the button clicked "before" i click sign on, sign off, beach open or beach closed.
I do not know how to reference these buttons in my code as for starters, they are numbers, which is a big no no apparently. Also, even if i change the name from just a number to something like cmdBeach(i) when creating them, i still can't refer back to cmdBeach5 in my code as the button doesn't exist yet

This may sound quite basic, but i was wondering how to change the value of a variable in an array, not knowing the index value but knowing what the variable is.
For example, I have an array and I want all strings within it that haven't got a value to say "Stretched". here is what i have tried:
For Each stl As String In Me.stl
If stl = "" Then
stl = "Centered"
End If
Next
My array is called stl(), and the size of it is always changing, so i can't just change the specific variables within the array
Also, is there some way to show/change etc all variables in an array? e.g. msgbox(stl(all))
I know this won't work, but what will?

I have made a For next loop with an array. I want all my picture boxes to follow each other within the loop. I have currently been using old code, but not in a loop or array format. The old code works. The array code only makes the 2nd picture box follow the FIRST one. It doesn't loop the rest. I have checked the code and cannot determine any mistakes, else I'm missing out on something I haven't been taught.[code]...

I haven't managed to find it and it is driving me nuts! If I have a structure such as

If I want to change a single element of one of the elements of the array, for example the DayHi field of the 0th element, then the code ATRList(0).DayHi = 4 causes the error: Error3Expression is a value and therefore cannot be the target of an assignment. Now I could get round this by reading all the items out of the 0th element into newATR, changing the field I'm interested in and then doing a "ATRList(n) = newATR" but there must be an easier way?

I am storing an array of a custom serializable class in session on my site. When a page on the site changes, suddenly it renders them invalid, and tells me that it can't cast the type to it's own type. I assume the class version numbers are changing or something?!
I'm not trying to redesign this whole process.
Unable to cast object of type 'ShipmentPackages[]' to type 'ShipmentPackages[]'.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I've been trying to reuse my bosses vb.net buildpacket code which he has successful used for Serial programming eg. SerialPort1.Write(buildpacket(useraddress,252,"0006","0") for the function listed below.My challenge.Create equivalent functionality for Socket BeginSend() which requires a byte array.Whether modifying the vb.net below or getting a c# equivalent to work, it has been repeatedly recommended to scrap the string concatenation approach for which I have to use Encoding.BigEndianUnicode.GetBytes() and then getting rid of extra bytes with zero values.
I'm lacking in imaging something different which would work for socket programming directly and allow me to eliminate all the hassles that c# integer conversions into string value that can be encoded trouble free.I would need to call the equivalent of the following that would return a byte array rather than a string with the following arguments
1. Source address (0-255)
2. Destination address (0-255)
3. Function code ("0001" through "0100")
4 Packet Data Unit (pdu - some integer value

I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12
