Create A Listbox On The Fly (at Runtime)?
Feb 18, 2011
I'm attempting to create a listbox when a button is clicked in Visual Basic 2008. I can't seem to find code that works to do this.
Dim lstOutput As ListBox
lstOutput = Me.Controls.Add("VB.Label", "List1")
Problem is that both of the things inside the parenthesis generate errors:For the first one:Value of type 'String' cannot be converted to 'System.Windows.Forms.Control'.And the second one:Too many arguments to 'Public Overridable Sub Add(value As System.Windows.Forms.Control)'.

I can build the tabstrip fine and name it - that part is from what I can see the easy bit.What I want to do is select a tab then create a listbox on that tab, and then pupulate the list box with data.
For this test I am using the event viewer.
The system loades the logs into memory, and then creates however many system logs there are ie application, system security etc etc.
But how the hell do I select one of these tabs then draw a listbox and then address the list box - Ideally the list boxes etc will be created at the time of the tab?[code]...

I have created a Visual Basic ActiveX DLL project. The output of this project ( a dll )gets loaded inside VB6 runtime i.e. a process which is loaded with msvbvm60.dll. I used Visual Basic 6.0 IDE ( vb6.exe:name of compiler ) to create this project. Now my requirement is to create a similar dll which can run inside VB5 runtime ( msvbvm50.dll ). I assumed that there should be some Visual Basic 5 IDE ( vb5.exe ) which can be used to create VB5 runtime compatible dll, but could not find one

A while back I asked a question on how to create EXEs at dynamically at runtime. This time, I wanted to know how to add code to your program dynamically at runtime too. Like if I had a textbox on a form, and I typed whatever code into it, then it would add the code to a subroutine and it would be executed. How can this be done?

I have a form that depending on results from a table would create a number of buttons using code at runtime. This could range from 1 to 20 buttons. What I am struggling with is creating a generic mouse over event for each of these buttons? The reason why I want a generic mouseover event is that depending on the text on the button I would do certain things, instead of duplicating the same code in individual mouseover events.

Background: ok I have an app that hides in the system tray. During its operations in the background it can try to invoke an outside app several times.. and I need to track when the call errors out.. I was using messagebox's but for some reason if the app hidden the messagebox's dont come up and goto the forefront. So in reading about this I read I should just use a form to do it.. so I did.. works fine.. well works fine for one error.. but if the user tries to do 3 of the same operation.. and lets say first errors.. second works and third fails.. using one error form wont work.. since I diaplay the error one.. then need to display error 2.. I need 2 error forms so they can click OK on both.[code]...

The exact error that was thrown was a MissingMethodException,and was caught like
thisExceptions.Domain.GeneralException was caught Message="UpdateVendorFileProcessingWeek, Method not found: 'Int64 DataAccess.Manager.VendorFileHistoryManager.GetVendorFileHistoryID( Int64, System.DateTime, Boolean)'."
Source="Domain"
[code]....
there's a series of shared functions being used;everything compiles and builds ok - it's only during runtime that the error is thrown;the code itself DOES NOT use reflection to find any methods (but obviously the frameworkis doing some reflection)?
