I'm programming a basic slot machine in Visual basic, and want to use a for loop to randomly choose the image for each slot, display the image in each slot, and change the slotName variable (so I can check later on which symbols are in the slots) for each slot. The problem I'm finding with a for loop is that the variables and objects for each slot have different names (slot1Name, slot2Name, slot3Name, lblSlot1, lblSlot2, lblSlot3, etc). Is there any way I could have could something like: currentSlotName = "slot" & i & "Name"
This is the code at the moment, this code is repeated (with different variable and object names), for each of the 3 slots, which is pretty inefficient. ' Randomise numbers and assign images to slots based on random numbers, if the hold isn't on ' Slot 1 If Not held1 Then slot1Value = Int(Rnd() * numbersGenerated + 0.5) Select Case slot1Value [Code] .....
I am using the following function to Convert a String variable to a Date. Subtract a day from it and convert the date back to a String. The code goes as follows
[Code]...
If edate has a value 29/12/2011 than the value in expenddt gets changed to a different format and the value in expenddt comes to 12/29/2011 and later after subtracting a day expenddt is 12/28/2011 and than when i convert it back to a String i get the value in asd as "12/28/2012 12:00:00 AM"
I have a string value of form names in my DB so when my condition passes, the variable string will take over the value , then that value will call the form(variable) as string.
I am developing an application which initially allows the user to browse and select a save location. The selected path is assigned to a public variable which is used with concatenation to crate folder for saving user input data. How can I change the path string to a constant so the user can run the program again without having to run setup routine unless they want to change the save location?
I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).
I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
I am trying to insert a string variable inside of two strings, and make a combined string. Public Sub Page_Load() Dim Id As String Id = Trim (Request.QueryString("Id")) End Sub Dim mp3text as string url... & Id & ".mp3" My goal is to make the mp3text variable have a string that is: url...(If Id is 7) It is for some reason not connecting up correctly. I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"
These is the content of my txt file which is saved in D drive in my pc abc,1,2,3..I tried the flowing but it didn't work:[code]I am getting error on this line.. data = line.Split(","c)...it says this line isn't in use anymore or something and that I rather use LineInput but thats asks for filenumber and i don't know what that is. I am sorry but I am a complete beginner. what else can I try? [code]ok that error is gone now but now if I want to add these values to a list box..how can i do that?
I have a variable (double) which has a constantly (infinitely) changing value. I would like to store all the values of this ONE variable into an array. My variable and array are:
Dim x as Double Private y as Double() = New Double (499) {} I tried doing this:
I'm working on a home project using DirectShow.Net. to learn some VB.net. Most of the examples I've found have all been in C# so I'm looking through code for ideas and converting where I need to. I keep stumbling upon these declarations and I'm unsure how to convert it to a VB.Net statement.[code]Then the second part seems to be assigning the value but as its made up of two parts im unsure how that works?
I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.
EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:
Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String()) Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex))) End Function
I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin dec2oct dec2hex bin2dec oct2dec hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
Is there any way to convert null terminated string to normal string.I mean I can easily make a program to find the location of vbnull but there has to be a built in function for that.
how can i convert these datatypes: date to string and integer to string.Because it must be in a string datatype when I display it in a datetimepicker and textbox.
just found out that replace(string does not do the same as string.replace when my string variable was an empty str the first one returns "nothing" and the second returns an empty string (as expected).just sloppy coding anyhow, it was a function that was converted from classic asp and never rewritten properly.

Currently, I'm using the following code to pull info from the management class.
[code]...
I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.
