How To Assign Function That Returns Value To Variable
Apr 26, 2011
So I have a class called Transactions and I put all my functions there. The problem is, when I try to call that specific function and assign it to a variable, there is a "ByRef Argument Type mismatch" error that keeps on bugging me.
Public Function GetUserID(name As String) As Integer
Dim gotID As Integer
Dim rec As Recordset
Call connectDB
sSQL = "select ID from User where Name ='" & name & "'"
Set rec = CurrentDb.OpenRecordset(sSQL)

It's often the case that I can write a nice tight little VB.NET function, and when it comes time to do the Return statement, it's really natural to just return the result of a quick calculation or a method call. However, this makes it difficult if I need to step through the debugger to see what is going to be returned from that Function. For example, take this simple method to illustrate the concept[code]...

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 need to assign a varible in a while clause. I.e., i would do it in php like this: while (!is_bool($char=$this->getChar()) in every loop, the function would assign $char a value, the is_bool function would test it, and the code INSIDE the while clause would have access to that $char.

I want to assign a string value to a variable in the DataGridView LostFocus event. I found that I can't just do variable = "string value, it will give me the "Unable to cast object of type 'system.eventargs' to type 'system.windows.forms.datagridviewcelleventargs'" error.
The function created by double-clicking on the datagridview is:
Private Sub DataGridViewInvoice_LostFocus(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridViewInvoice.LostFocus

I'm trying to retrieve data from an access database, but I'm trying to do it all in VB. Basically I need to query the database, and I think I've done that correctly. But then I need to assign the value in a certain field, to a variable. So for example,
Dim email = orders.CustomerEmail.
How to assign a value to a variable.
Below is my current code:
Dim acc
As
New AccessDataSource()
accDS.SelectCommand = "SELECT TOP 1 orders.OrderDate, orders.OrderNumber, orders.OrderProduct, orders.OrderTotal, orders.CustomerName, orders.CustomerPostCode, orders.CustomerEmail"
accDS.DataFile = "~/App_Data/Database.mdb"

I get nothing but headaches when I try to update settings in the My.Settings class, or when I try to assign a newly assigned setting to a variable. Sometimes the settings update OK at run time; other times times they update only after the application closes; and other times still they appear to update at run-time, then when I close the program and reopen- they go back to the previous settings.This is how I assign a value to a my settings and how I assign a setting value to a variable.[code]

I wrote a vb program that would prompt the user to enter a number and then enter the exponent value they wanted the number raised to. When they clicked button 3 it did the calculation. everything worked perfectly.
Now I need to change the program. I must create a function in a module and then call that function from button3 click event. I have tried several different ways and even though it seems to "work", it keeps returning an incorrect value![code]...

I think I remember reading somewhere that it was possible to assign items to a variable if the item inherited from a base class, but I can't remember how.
I want to have a class that gets properties set and one of the properties is an error code property. I want to assign any exceptions that occur to the property, but it could be any type of exception. I remember that all exceptions inherit from the Exception class.
How can I assign an exception to a property based on the class it inherits from?

Any way to attempt to assign a variable within a data class or structure when I have the variable name as a string. Where would this be useful? Let's say I have a data class that exactly mirrors the columns of a table in a SQL database. This lets programmers easily interact with table row data as it gets passed around as an actual, specific object since Intellisense can enumerate the variables for them, etc.
However, populating such an object is tedious and repetitive--the programmer who creates the new object has to one by one match up all the members when reading from the SQL data adapter. It would be nice if they could somehow enumerate all the variables in that class and attempt to auto-assign the values from the database instead of having to build a custom population method for each new data class. A person could create a hash table or tree or something that pairs member names with actual objects.

I'm wondering if it is a typo. Do they actually really wanted to say: the implementation of the JVM is free to instead of the compiler is free to.
and my second question is that do we have this issue with C#/VB as well? (in which the ""compiler"" is free to assign a value to a variable even before the variable is fully initiated/even before the constructor function of the class of the variable is fully ran.

Is it possible to declare a variable and to choose it's appropriate type during runtime?
it should be something like this (of course, the last line does not work):
'Determine what type of variable is needed later
Dim myVariableType As System.Type = System.Type.GetType("System.String", True, True)
'Create variable with needed type
Dim myVariable As myVariableType ' Should be a string variable in this case

I need top create a function that gets the next integer in the sequence of 1 to 60. Each time the function is called, I need it to increment from what the last value was and return the next number as the result. It also cannot return the same integer in 2 consecutive calls. When the count gets to 60, the sequence needs to reset back to 1. I would like to function to have no parameters.
I have created a function that does this using the cache to store the last value that was returned, but I am worried that with concurrent calls to the function that it might not work as I expect and 2 calls could get the same integer.
Is cache blocking the correct method to use in this instance or is there something other method I am not thinking about?
Also, stuck using .Net 3.5 and this is a web application.
I just wrote this function based on using SyncLock. Any obvious problems with it that I don't see? I am using the Cache to save the last value that was returned.

Dim r As Integer
