MethodBase - Any Way To Get Argument Values Dynamically?
Oct 5, 2009
Is It possible to get the arguments' values used in the previous execution method?
For example:
Public Sub GetPreviousMethod()
Dim stackTrace As StackTrace = New StackTrace
Dim stackFrame As StackFrame = stackTrace.GetFrame(1)
'MethodBase: Get the previous method
Dim methodBase As MethodBase = stackFrame.GetMethod()
End Sub
If I use 'methodBase.Name', It works 100% and return the method name. I got the arguments' names of this methodBase using Reflection, and is It possible to get dynamically the values of the arguments?

i have used following code to repeat a process creation/close iteratively dim vProcessInfo as new ProcessInfo For i= 1 to 100 dim p as new Process vProcessInfo.Arguments = some"+i.toString() p.StartInfo = vProcessInfo p.Start() p.WaitForExit() p.Close() Next i the above code worked for me successfully. but it takes too much time for process creation and dispose. i had to change process argument dynamically in the iteration. is there any way to change the process argument dynamically. or is there any better method to reduce time.

This maybe academic but I'd like to be able to pass the MethodBase.GetCurrentMethod() to another function. That way I could split apart the different parameters in one place. What I'm currently doing is something like this...
Sub SomeSub()
Try

i'm trying to do a filename compare, sort of fuzzy match.Here's what code i have.First of all i load 2 directory's into 2 listbox's as strings and remove the filepath. Directory1
Code:
TextBox1.Text = FolderBrowserDialog1.SelectedPath
If TextBox1.Text = "" Then
Else
Then when i click the compare button i am trying to pass listbox1 and listbox2 through Distance and return the resulting fuzzy file matches.
Code:
Dim MyObject As New StringSift2
Dim ReturnVal As Single
ReturnVal = MyObject.Distance(ListBox1.SelectedItem, ListBox2.SelectedItem)
[code]....
But i get this error.
Code:
TreeView1.Nodes(lb1).Nodes.Add(ReturnVal.ToString())Specified argument was out of the range of valid values. Parameter name: index

I made this procedure re-use a select query:
[code..]
And I use it like this if I would want the selected value placed in a textbox and it works fine
[code...]
However if I want the value to be passed in a string like so:
[code...]
The string ends up having an empty string value. How do I assign the value I queried to that String?

Greetings, I'm sure there's a simple solution to my question, but I haven't figured it out yet. I have a Form with 12 Label objects L1-L12. I'm trying to set the ".Text" values of those label objects with the values of the fields in a Database table,,, Here's what I have. It DOES NOT get errors. But it doesn't work either.

How can I do this:
Dim oMyObject As New MyObject
oMyObject.DoSomething("Parameter1","Parameter2")
The "DoSomething" and the two parameters are dynamically provided from another script. They are stored in a string object in this script: sAction & sParameters. My question is how can I dynamically pass the "sAction" to the object oMyObject.For example oMyObject.sAction (where sAction should be the value stored in the sAction string). The example will probably not work. Is there a way to do this? The idea behind is to avoid having to write each function hardcoded, like:
If sAction = "DoSomething" then
oMyObject.DoSomething(sParameters)
ElseIf sAction = "AnotherThing" then

how to assign a 1-dimensional array value I get from a function directly into an element in a 2-dimensional array. An example would be
Dim Results(7)() as DoubleResults(0) = myFunction() ' returns an array with 5 doubles What is the correct syntax for this, if any? I'm still having a bit of difficulty switching over from Python arrays, which work a lot better, it seems.

I have a WPF application that allows users to create questions of all different types which depending on the type will use a textbox,combobox,checkboxes, or radio buttons to allow the user to answer the question after they build some sort of questionnaire. My question is what is the best way to keep track of the answers across all the different controls after the controls are created and the questionnaire is created on the fly. Right now, i'm looping through all the containers and getting the values based on the controlType.

How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically.

I am writing a mvc 3 application and part of its function is to send out confirmation emails along with an assortment of other emails.. I have the body's for the different types of emails stored in a database table.. Getting the values out of the table and dropping them in a email body using System.Net.Mail isnt a problem at all... What I need to do is somehow put somekind of variable marker in the body which is in the database table and then somehow parse the body text when its dropped into the email body to find the variable marker and put the correct value in it's spot..Code snippet of what I have so far is below:
Keep in mind that this will be a rather large body and there are a few places values will have to be dropped in.. I was thinking of having it use something like this:
Long mail body ^^Name^^ has been approved for classes starting on ^^Date^^ at the ^^Place^^ located in ^^Location^^..
When the code loades the text from the body when ever it comes across a variable marked with ^^ it would put the correct information in its place...
Dim _content As email = db.emails.Where(Function(f) f.ref_name = "Confirmation")
Dim _body As String = _content.email_body.ToString
Dim SmtpServer As New SmtpClient()

I have an asp.net web forms application. In this application, students upload assignments and submit a survey along with it. For the survey, I read values from DB and dynamically generate ASP.NET Controls like radiobuttonlist, checkboxlist, textbox on the form during gridview's RowDataBound Event. I cannot do it in Page_Init method because I create only if a user click on a specific assignment which requires a survey to be submitted.
When I submit the survey form, the survey values are not saved into database. During debugging I figured it out that the values are not available in the codebehind page. The radiobuttonlist.selectedvalue returns and I get following error[code]....

I want to choose a value dynamically from comboBox depending of the values selected previously in two comboBoxes.the code that loads the comboBoxes:
Private Sub LightClassComboBox_DropDown(ByVal sender As Object, ByVal e As System.EventArgs) Handles AreaClasificationComboBox.DropDown
TrafficDensityComboBox.DropDown,.....
[code]....
The problem is that in the last Sub in the If sentence gives an error of: Null Reference Exception, because the compiler thinks that in that event the data are not loaded, although the data are loaded when loadcomboBoxes sub is executed.

I have declared an array of text boxes created dynamically at run time. The textboxes are assigned some values by user. The text boxes are located in a Form so that once the user fills in the info and clicks the "ok" button, these values are passed at the back end and the form dissappears. However the user can bring back the form again by clicking another button.
The problem is that once the form reappears, the information previously provided in the form remains. Even the user clears the text boxes to provide new value, the text boxes at code behind do not receive these values.

I have this code.
Code:

Dim NPB As Button
Dim x As Integer

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

Does Visual Basic 2010 allow this functionality, directly or indirectly?
