I have a text file which I open and then read in 1 line at a time and split up. I then takes each component part from the split string and assign it into a variable as I go.
I then want to specific varaibles and put them into an array and build the array.
Can I read in each element and assign it directly into an array or is this was best.

basically i've gotten myself into a mess with some last minute project work. shame on me and all that but thats college students for ya. basically i seem to be having problems assiging a simple integer to some pictures in an array. now. basically its a card deck. i've looked this up so many times yet nothing comes to me that fits my code or the way i've been taught. in any case i've got an imagelist and put it into an array to symbolize a deck. now. as i'm doing blackjack i need each card to have its own value. so obviously 2 of hearts value = 2, king = 10 etc.so what i've done is created a function that calls on a string. and used a select case to give a value based on the filepath of the image. however it failed hoplessly. heres a piece of the code:
Sub getcardvalues(ByVal card As String)
Select Case card
Case "decklist.images.item(2club.png)"
value = 2
[code]....
despite this seemingly simple solution i can't seem to pull out the path of these cards as a string. the array simply gives me a number and the actual picture dosnt want to be a string. so my question is this. how can i pull the image path out of the array (eg: deck(1) = decklist.images.item(3club.png)) and turn that into a useable string?
I am having a problem with objects and arrays of objects. Basically obj_stored holds how many objects I have stored in my text file, in this case t shirts. line(y) is an array that holds each line that has been read from the text file. I then use this to assign values to my array objects properties. For example I know the first line is the color of the first t shirt, second size, third price etc. Then I know the next line will be the color of a new t shirt. There are 6 t shirts in the file.
Dim t_shirt(5) As Clothing.t_shirt
Dim t_shirt_purchased As New Clothing.t_shirt
For x = 0 To obj_stored
t_shirt(x) = Clothing
t_shirt(x).color = line(y)
y = y + 1
t_shirt(x).size = line(y)
y = y + 1
t_shirt(x).price = line(y)
y = y + 1
Next
MsgBox (t_shirt(4).size)
My problem is it seems to be resetting these values after it has finished. Im creating the object each time and assigning values to it's properties but when it's finished it all resets and says 'Object reference not set to an instance of an object'. I'm new to OOP and was wondering what sort of approach i would take to doing this, if the one i am taking is wrong.
So I am aiming to:
Read everything in from the text file.
Create new instances of the objects depending on how many t shirts are stored, (5 t shirts = 5 objects)
Assign the values to my objects properties.

View 3 RepliesI am stuck on how to assign values on a label or text box.The issue is the following:I have two tables, one called A and the second one called B.Table A has tree fields: id, name, lastname...Table B has five fields: id, level1, level2, level3, level4..The idea is to save A.id into level1, level2, level3 and level4. A.id can be the same or not. I know how to assign and save the values on the DDBB using DDL, but when I want to show the values using labels, I get the first value always, this is becuase the select command is configures in that way. If I use ddl instead label, it works, but I do not want to show the value using ddl. I want to use label to show the values, and ddl to modify or add new data into the DDBB.[code] As you can see the level1 uses label, and level2 uses ddl, it was the only way to get the value for level2, otherwise if I use label on level2 it display level1 value instead.I would like to know if there is any way to assign different value using anything but ddl.

This works perfectly:
Dim N As BigInteger
N = 28 'Put whatever value you want in for N.
Write((BigInteger.Log(N) / BigInteger.Log(2) + 1) / 2)
This does not work:
Dim Result As BigInteger = (BigInteger.Log(N) / BigInteger.Log(2) + 1) / 2
This gives an error during the build (despite the variable being declared as a BigInteger and the operation working perfectly well when I am not assigning it to a variable, it tells me I can't convert a Double to a BigInteger) and I have to do this:
Dim Result As BigInteger = CType((((BigInteger.Log(N) / BigInteger.Log(2)) + 1) / 2), BigInteger)
This if course gives a different, that is, incorrect result.'This doesn't work either.
Dim Result As BigInteger = BigInteger.Log(N)

I am trying to make a VB User Interface with Visual Basic Express Edition 2005 where clients can do the following calculation: Stranding x Bare Copper CMA = Total CMA
I have created an access 2007 database called Total_CMA, this database has 2 columns, one with the SIZE and the other AREA, but in this database the Size = Area ( was not sure how to set that up properly ) so I left it at 2 columns and then went to VB and set up with a listbox for the Size and have bound the database to this listbox, and when I debug it, the numbers for Size show up in the listbox, so thats looking good so far, since the size = area when I bound it it asked to get and I picked Size then it asked value equals so I picked Area and hope that was the proper thing to do.
I added a TEXTBOX named STRANDS for the customer to input the number of strands, then a button to click to calculate total CMA and another Textbox named TOTAL to display the results. All have labels next to them naming what they are.
My question is, how do I get what the customer selects in the listbox to multiply by the STRANDS textbox and output in the TOTAL textbox when clicked on the button to calculate total CMA. I also need to make sure whatever SIZE they picked in the listbox is going to take the AREA number ( not the SIZE number ) and multiply it by the STRANDS textbox.
