basically, i get "Object reference not set to an instance of an object" on the line:
example Dim x As Integer = objPlayer.Hand.Count
this line is in the object Dealer, but as far as i can tell i've declared everything correctly ...
i was told that i had to pass the values to the object or something, but not how to do it
For the past 2 days i have been trying to come up with a simple solution for this problem, but i have turned up nothing so far.[code]What i am thinking now, is if there was a way to get the "name" and "value" field with the 1 regular expression, instead of having to do the 2, would that be possible?

View 1 RepliesI have a subclass created called symbol with 4 sub values of integer type, left/right/above/below I am storing them all in an array, adding them one by one, each time I re generate the "symbol" and assign its values using randomize + rnd() Yet for some obscure reason everytime I put a new symbol in my array, all the older symbols all change. No where at all in my script do I manipulate their values, they just change on their own.
I'm thinking it might be some kind of benign compiler error where it is actually assigning a pointer to rnd()'s value to a int in a class in an array, as opposed to its actual value at that point in time.It's the only thing I can think of. I'l try storing them in a list instead but I'm also trying to store the array's of symbols I generate in a second array, creating a 2 dimensional array of symbols (of which I then proceed to convert into actual symbols based on the 4 random numbers generated and then combine into a string which I output to text)
Thus I'd need to make a 2 dimensional list, which is not nearly as easy as a 2 dimensional array >.< Everything else in my program works fine except for the fact that because of this error every single symbol is exactly the same.I know this is all happening because I stepped through the process watching it line by line in debug mod and monitoring the values. The values all change the moment I reassign a new Randomize, every one of them changes.

In my program, I can place an order for glasses.To do this, I have 4 text boxes:
StockNumber: [12345]
GlassOrPlastic: [Glass/Plastic]
ScratchCoating: [Yes/No]
UVFilter: [Yes/No]
Currently, it works fine... BUT I need to type in Glass or Plastic, I need to type Yes/No and same for each thing, wondering would checkboxes be more effecient or how would I do it?How do I even use checkboxes to get the same values...(If I type in Glass it adds �30 to the price, if I type in Plastic only �15 is added...)So if a Yes answer = �20 and a No = �10 How can I do that with checkboxes or whatever...My code for when I click the order button, myAddNew just adds my information in..

View 3 RepliesReading a book, the following examples are given regarding value and reference types. This example is noted as a value example. ptY display {x = 10, y = 20}
Dim ptX As New System.Drawing.Point(10, 20)
Dim ptY As New System.Drawing.Point
ptY = ptX
ptX.X = 200
Console.WriteLine(ptY.ToString())
This example is noted as a reference example. objY displays "Hello Test".
Dim objX As New System.Text.StringBuilder("Hello World")
Dim objY As System.Text.StringBuilder
objY = objX
objX.Replace("World", "Test")
Console.WriteLine(objY.ToString())

I need to check the size of textboxes in a webpage. I have already written the function which retrieves the maximum size of textbox and which writes the html codes of the webpage in a textfile. suppose i have these lines in my textfile:
<input type=text name=firstname size=30/>
<input type=text name=surname size=50/>
<input type=text name=address size=40/>
How can i change the size of all textboxes to 50 (the maximum size) in the textfile itself?

View 2 RepliesI am having some major problems with byte arrays. First off the bigger array I have the more values go missing, I originally wanted to make a huge array and just dump like a 100mb chunk of memory in it but when I did that every byte in the array returned 0. So I experimented a bit and found 4kb to be the biggest chunk size to reliably not return 0.. ok I figured I'll just loop the 4kb and glue them back together later but no such luck, after being combined into the main array the bigger the number gets the more values that should be there just aren't.
Here's a code sample:
Dim retval(4095) As Byte
Dim combval(RLen) As Byte
For i = 0 To RLen - 4095 Step 4096
ReadProcessMemory(ProcAccess, i, retval, 4096, 0)
retval.CopyTo(combval, i)
Next i
WriteLine(combval(321603964))
WriteLine(ReadMemory(321603964, 1)(0))
So with the last 2 lines if I pull up some smaller number like 8 digits or so it reports back no problem but anything slightly bigger like the number i have written in there right now is just 0. After some additional research I discovered that the reason why 4kb is the max size I can reliably get is coz that's the size memory chunks are made of, "page" as they call it. Why the memory reading drops off at higher addresses alltho I suspect it has something to do with the way memory is structured and I am just not hitting the startpoint of a page anymore due to an offset or something somewhere.
I have tried to solve this myself and I know I am probably doing something really silly here what I have is two different registry values that control what is displayed in the combobox on my form RegistryKey1 has the following values:0,1 or it does not existRegistryKey2 has the following values2,3, or 4 the combobox has the following values 0,1,2,3 However here is the problem if the RegistryKey2 is 2 then it further has to be checked if RegistryKey1 is either 0,1 or does not exist
if it is 1 then the selectedindex = 0
if it is 0 or does not exist then the selectedindex = 1
if RegistryKey2 is 3 then the selectedindex = 2
[code].....
as title says. and if it has the same values, delete one of them and add (2)
so itll be like: - before the filter:
