Add Description To Functions And Function Parameters?
Apr 19, 2011
I'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..
We know some functions in dll files and can use them but if we haw a dll file and dont know functions names. is there a way to get the functions name and their parameters
How is it possible to add a function description in VB.NET (VS 2005)? in C# this task is resumed to tape 3 times the "/" simbol just above the function declaration. (generates the <summary> tag and others)
I do need to write a procedure that carries an array as a parameter- The array can be an array of many types (Dates, Double, Strings etc)- The number of elements in the array is unknownExample:Private Sub MyArrayRoutine(MyFirstPatameter as string, MyArray as array of Object()
is there a way to get the GET parameters and POST parameters in just one function or Collection in ASP.NET? Like using $_REQUEST in PHP? I'm using VB.NET.
Well I am a new to VB.NET, converting a legacy system to .NET world. Recently I have been reviewing the already existing code since I joined the project quite late in the team. I find that there are many shared functions (not shared class) inside many classes. I doubt this may create some problem if two requests ( i.e two different HTTP request to the same method as it's a WCF application, of course exposed methods are not shared but internally called methods are shared) comes to the same shared method and both the calls to the method may have different method parameters/arguments, overwriting each other's arguments. In short, if shared method has a list of arguments which is going to be processed, is there any chance of inconsistencies in the light of multiple access to the shared method via two http requests.
I'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.
I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.
I just got upgraded from VB6.0 to VB2010. I'm trying to move some of my program functions over and I'm getting an error on the ones where I use optional... Public Function GetFolder(ByRef FTT As String, Optional InitFile As String)
I get the error at the end of the line, after the close par...the error is "optional parameters must specify a default value".
i want to get all available midi device by name. i found this: Declare Function midiOutGetID Lib "winmm.dll" (ByVal hMidiOUT As Integer, ByRef DeviceName As String) As Integer
[[code] 1) Is this violating the phrase static classes should not have state?
2) How can I modify the functions such that they can accept any function (instead of my above situation which only works with F(TResult) and F(T, TResult). [code]
Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object.
I get this error: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
Partial Class _Default Inherits System.Web.UI.Page <WebMethod()> _
[Code]....
I know it has something to do with the fact that the first function is shared and the second function should probably be Public as well but I don't fully understand the reason behind it. Probably not relevant but I'm calling the web method from some javascript.
I am currently working on a project witch contains lots of functions and properties. These functions and properties are stored in the dll. If I reference to this from within my project, these functions and properties are all in the same namespace or class. (I don;t know how it is called)Example:If I type the root namespace: Functions. I get all the functions. I would like to organize them in:
Functions.Maths (All the functions involving maths) Functions.Internet (All the functions involving the internet) Functions.Language (All the functions involving languages)
I tried using classes but I cant access the properties when they are stored in a class. I don't know why.
where 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.
Public Sub sqlUpdate(ByVal table As String, ByVal column As String, ByVal var1 As String, ByVal column1 As String, ByVal var2 As String) Public CN As New MySqlConnection Public cmd As New MySqlCommand
[CODE]...
Which is fine, if I want to use mysql update all I have to do is call something like: sqlUpdate("test", "test", 0, "test", test) I was wondering if I could do the same with the SELECT statement and make a function. I cant think of a way to do it though...
sqlConnect() Dim cmd As New MySqlCommand With cmd .CommandText = "SELECT * FROM users WHERE username=""" & lblAccountName.Text & """"
[CODE]...
The data I would want to extract would be different every time.
I have to create a program that finds the total cost for pizza, fries, and soft drinks, and places that in a list box. So far, though, I'm stuck. I have this code so far:
Public Class frmBill Private Sub btnTotal_Click(ByVal sender As System.Object, [Code] .....
The errors that I am getting are: "Argument not specified for parameter 'D' of Public Function totalBill(P As Double, F As Double, D As Double) "Argument not specified for parameter 'F' of Public Function totalBill(P As Double, F As Double, D As Double) "Argument not specified for parameter 'P' of Public Function totalBill(P As Double, F As Double, D As Double)"
i am using XML as database, so updating or inserting diffrent XML's currently i am manage a seprate class for seprate XML file, this process consuming my lot of time, i want to create a genrelize class. currently according to the XML need i am sending two, three, four or five parameter in my function.
now i want to send array of the parameter to my function, so becoz of this thing i could mange all of my functions via a single class...
i am sending u the example what currently i use now...
Public Function Update(ByVal Item_ID As Long, ByVal ProductName As String, ByVal Price As Long, ByVal Path As String) As Long Try
Can we pass parameters to a function using delegates
Private Sub UpdateLabel(byval text as string) If Me.Label1.InvokeRequired Then Me.Label1.Invoke(New MethodInvoker(AddressOf UpdateLabel)) Else Label1.Text = text
I need to convert the following C# code to VB.NET:
public bool TryGetRewriteMatch(UrlContext url, out RedirectMatch match) { // NOTE: Normally this would use regular expression matches, cached database
[Code].....
However, I need to reference Url and ProductID in the function and I don't know how to pass them as parameters or get their values from the original function.
What is the preferred method of adding the current date/time into an SQL Server table with INSERT Command and executenonquery? I'm expecting something like ...
