View 3 RepliesSetting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters
Feb 17, 2011I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.
Asp.net - Reference Property Of An Unknown Type In Lambda Function
May 18, 2011I'm trying to create a generic function to build a Linq expression from a list of Telerik grid filters. I'm trying to stay clear of dynamic Linq. Because I don't know the type that I'm building the expression for, I'm attempting to use reflection in the lambda functions to refer to a property, but after applying the fix suggested by @JaredPar I get the error, "The LINQ expression node type 'Invoke' is not supported in LINQ to Entities." Is there any way around this? here is my code:
Public Shared Function buildRadFilter(Of T)(ByVal filterExpression As List(Of GridFilterExpression)) As Expressions.Expression(Of Func(Of T, Boolean))
Dim returnPred = PredicateBuilder.True(Of T)()

Changing Unknown Number Of Label Captions Using Unknown Length Array
Oct 22, 2009Using Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.
I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

Debugger When A Function Has A Lot Of Parameters?
Jan 21, 2010where the VS debugger refuses to show certain field types including dates.My call stack contains FunctionA which calls FunctionB. FunctionB has about 45 parameters and many of them are dates.When I step into functionA,
1. the debugger refuses to show a date variable when you hold the mouse over it. It just shows {Date} instead of a value
2. If you do quick watch on that same variable, it also just shows {Date} instead of a value
3. If I do ?variablename in the immediate window, I get "System Error &H80131c23&"
When I comment out the call to functionB, the date variables all show correctly in all the above methods. I will stress that the code has not yet reached functionB, just its very existence in code screws up the debugger.I'm thinking this is a memory issue and maybe vs debugger can't cope with a huge function stack frame dataspace.devenv is only using 268Meg of ram on a 2Meg box, with not much else running. Thats reasonable for this size of project.

Add Description To Functions And Function Parameters?
Apr 19, 2011I'm writing a VB.NET function with a ton of overloads. I've seen that most .NET functions have parameter descriptions in IntelliSense. For example, when typing in String.Compare(, IntelliSense says Compares two specified System.String objects and returns... you get the idea. This description changes and you click through different overloaded versions of the same functions. When you start typing in something for a parameter, it describes the parameter you're currently inputting as well. Example: strA: The first string to compare..

View 3 RepliesShow Probable Parameters In Intellisense When Using A Function Or Sub?
Feb 18, 2012Suppose I have a function that accepts a string as parameter. But the parameter has a limited number of values (i.e. I've defined the function to work with only say, four exact strings). What I want is that when the user types the name of the function and starts the parentheses, the intellisense will show up giving the values that are defined in the function. Its just like a function that accepts a boolean parameter. The intellisense shows up giving the two values "True" and "False" when using the function.

VS 2010 - Parameters With Spaces (String Split Function)

parameter1/parameter2/parameter3
parameter2 is a datafile path which may sometimes have a space like :
C:Program Files est company
I did this as a work around
Sub Main(ByVal Args() As String)
dim cArgs as string=""

Asp.net - Building A Valid SQL Query With Optional Parameters For Search Function?
Oct 20, 2011I have a search function de build.We are using pure ASP.NET w VB.NET We have multiple DropDownLists and we're building a search query with whatever was selected in those DDLs. My question is, how can I handle the blank values (unselected dropdownlist values) with the SQL Query ? I'm using AND operators in the query so if anything is blank it'll fail the search. If the dropdownlist has no selected value, i don't want the value to be part of the search. It would be easy to code with just 2-3 parameters, but we're looking thru at least 10 items and doing a SWITCH CASE or multiple IFs would soon become mayhem.
