How To Make An Array Of MethodInfo

Mar 22, 2011

I do have to create at runtime a list that will contains some methods. These will be called in proper time.

So far, I used reflection and have made an array of methodInfo.

The problem is that these methods do have different signature, and I also need somehow to get the value of the arguments to follow their method.

And finally, I need to be able to put all this together and invoke these method when the time comes

Methodinfo.invoke Return Type Checking?

Apr 14, 2009

gv1 is a grid !!

gv1.DataSource = minfo.Invoke(Activator.CreateInstance(classtype), inputParameterStore)gv1.DataBind()

What i get from minfo.invoke i am binding to the grid gv1 !!! But unfortunately its not working for all minfo !!!! Few errors are like :
return type is not IListSource ,IEnumerable or IDataSource !!!!

Hence i need to check if :

minfo.Invoke(Activator.CreateInstance(classtype), inputParameterStore)

returns IEnumerable or IData Source or IListSource !how to do that ?Also if return type is none of these i should display the result in a Textfield by Serializing the data and displaying it as an XML?How to do that too?

Make A 2-dimensional Array?

Oct 10, 2009

i want to make a vb.net program that reads from a text file a movie, with the help of a Open Dialog (called openFD in my program) (we don't know how many movie we've got), the actors, the release date, the country, and the rating.

The text file look like this:

Movie1;Actor,Actor,Actor1;Date1;Country1;Rating1
Movie1;Actor,Actor,Actor1;Date2;Country2;Rating2
...

First question: How can I make a 2-dimensional array? line(0,0) - Movie1, ... , line (1,5) - Rating2. Here Is my try, but it's not good:

Dim line As ArrayList = New ArrayList()
Dim itm As ArrayList = New ArrayList()
Dim i As Integer = 0

[code]....

And here is the code for the Delete Button. It deletes a movie from the listbox, but the details of the deleted movie remains for the next one, I must delete the details for the deleted movie, too.

ListBox1.Items.Remove(ListBox1.SelectedItem.ToString)

Make An Array Of Different Controls?

Sep 3, 2010

I've been making a table control for a few days, and I've got to the point of making it capable of accepting new data. To do this, I'm making it generate a row of text boxes, combo boxes, and date selection windows along the row that you're entering data into.

I've tried using an array of 'control' types and changing them to whatever specific control I need as I generate it. That sort of works. For example, the code under 'Case "Employees"' below will make a combo box display on the form, but 'ControlArray(i).Items.Add' gives an error because it doesn't think that ControlArray(i) is actually a combobox yet.

You might also be interested to know that everything will have to be dynamically generated since the table I'm using will not always be the same (and the Select Case code will eventually be replaced by something that checks for relationships in the database).

Dim ControlArray(NumberOfColumns - 1) As Control
For i As Integer = 0 To NumberOfColumns - 1
ControlArray(i) = New TextBox

Make Array Of Constants?

Feb 23, 2010

I've got a situation where I need a table of constants in my app. It's actually a table of 43 formatting options where the description will appear in a drop down and the detailed settings will be used by the codeIt appears that VB can't do arrays of constants. So I've fiddled around with a Constructor in a class that creates a new array then loads up each element with hard-coded .Add statements. It doesn't seem elegant though.So I then decided to try an XML file, that I load in the Constructor and assign the contents to an array. This is what I've decided is the best, most elegant, option - but I'm throwing this question in to see what you people might recommend ! The data is mostly strings
