Retrieve Current Function Arguments List Including Passed Value?
Sep 28, 2011
I wrote a Log class that details the exception, including the method name and its arguments list,but I couldn't find any way to programmaticly retrieve the arguments values.in some forums it was said that its impossible mission. I find it very odd.my arguments list looks like:
argA As String = ?
argB As integer (Opional, Default value = 2) = ?
etc. only actual values are missing.

I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

Datediff calculates the no of months between two dates, Is there any function which lets you to calculate the same thing but also includes the current month. Datediff +1 would give the answer, but just wanted to know if theres any inbuilt method.

I'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.

Gentlemen, I have an application made by a Vendor that sends a set of arguments to an application I am working on. I am unsure how to "launch" my application with these arguments. The vendor's app is a service that runs and launches my application when necessary. I'm assuming i need to modify the main form's constructor, but not sure.

I have a ClickOnce application deployed to many workstations in my office. On it's first run it adds a registry key to the HKCU run group that adds itself with a "-minimize" argument. On each login the program starts and seeing the command line argument minimizes itself. However when a update is published the program does not update. If the program is run from its menu shortcut without arguments it runs fine. I then looked up how to update programmaticaly and put that code into my program to run at startup.
But my.application.isnetworkdeployed returns False when command line arguments are passed to the app and TRUE when run without command line arguments even though in both cases it is network deployed. Since my program starts up with command line arguments and stays minimized while the computer is on there is no reason for a user to close the program and reopen it through a menu item but as of right now that's the only way the program updates. Is this a bug or how ClickOnce is supposed to work?
Example: Create a new program. On the form add a textbox. In the Form load event put something like:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
TextBox1.Text = My.Application.Info.DirectoryPath.ToString & "" & My.Application.Info.AssemblyName & ".exe"
MsgBox("Is my app network deployed?: " & My.Application.IsNetworkDeployed)
End Sub
Deploy the app. Start it with a menu item and it returns True. Start it with any command like argument (use the path from the box) and it returns false. Why? How is that possible? The app didn't magically become non network deployed because it was passed a command line argument.

I have a button inside a one of my forms which contain a lot of coding and normally a lot of variables declaration.
Is there is a option/add-on that I can use/set that enable me to display all the variable used inside the sub or function I am currently working in?
All I can find is add-on to display the Properties/Methods and only Public variables inside the form or inside the class. but I need to list the local variables also.

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:
<script type="text/javascript">
function HelloWorld()
{
var yourName = $get('txtYourName').value;

I'm not having any errors from these pieces of code, they're just empty everytime. I'm wondering if I perhaps have created them incorrectly.
Dim l As New Log()
l.Log = "Attempted staff login with username [" & txtUsername.Text & "]"
l.LogId = 0
l.StaffId = 4
l.LogDate = Date.Now()
l.Insert()
.Insert() is picked up in my BLL layer by these two functions;

My issue is regarding overloaded functions of the already provided IIf function that would handle specific types. As you all know the IIf function provided returns objects, rather a specific type so for my needs I created a few overloaded function to do just that but with a specific type in mind. So having said I have IIf functions for types of booleans, strings, bytes, integers, etc etc.
Now my problem is when I'm trying to pass a byte value to this function that would return one of the two byte values. When I do this the designer keeps confusing my values as an integer value and calls for me to convert it to a byte. If I did this then it would defeat my entire purpose for creating these functions-which is to avoid any conversions. The only way I can solve this is by converting the whole statement itself or the true/false parameter parts individual to specify to the designer that these values are bytes. I'm just hoping there's a way of identifying the difference between bytes and integers..

I've tried searching for a way to get a list of all files + all files in all subdirs. I've tried a simple shell("dir /s /b > myfile.txt") but it doesn't work because of some Danish specific characters. I have looked at the "getfiles" method, but I can't get it to work

Is there a way to write a single function that will control validating the input to any textbox? How to pass control of it.
E.g.: My second try was to:
Dim CurrentTextBox As TextBox << Declare a global
Write a function that uses the global textbox and takes in 2 parameters, one determining the length it has to validate and the second telling it what to do once the input is verified
Public Sub ConfirmInput(length As Integer, which As Integer)
If (CurrentTextBox.TextLength < length) Then
CurrentTextBox.BackColor = vbRed
GoTo DONE
ElseIf (CurrentTextBox.TextLength > length) Then
CurrentTextBox.BackColor = vbRed
[Code] .....
My first try was to pass a textBox parameter to the ConfirmInput function but I believe that's the same problem as above.

I am in vb.net and have a function that will be accessed by multiple threads. Everything inside the function uses local variables. However, each thread will pass in its own dataset by reference. From what I have read the local variables should be no problem, but I think the dataset coming in is a concern. How should I control access / execution of this function to make sure that it is thread safe?

I am trying to get the value of the CategoryID so that I can insert that value into the database when an admin wants to update product features. The stored procedure that was written is for a ListView, so I was hoping I could put something hidden in there to get the ID. When I put the Hidden Field on the page and tried to get the ID, I got the error I mentioned in the title.
<ul id="categories">
