Refering To A Form Control Property From A Module Function / Sub?
Mar 7, 2012
I have a single form application with two modules. The first module holds all the Sub procedures that provide the filtering functionality for 3 DataGridViews on the form. The second module holds the Predicate of T functions that actually filter the List(Of T) objects that are bound to the DataGridView controls.
I split them into modules since I was starting to have difficulty organising and finding the procedures and functions if I held them all in the form code.In some cases I can happily both Get and Set form control properties from within the modules. In one case I simply can't, I suspect I may yet find some more instances as I test further. The offending line is in one of the Predicate of T functions:
If tWord.Length <= Investigator.NumericUpDown.Value Then Investigator is the Class name of the form.
I suspect my problem might be that the Predicate of T functions (which are collated in a module) are called from the DoWork procedure of a BackgroundWorker that is a component of the form - hence the DoWork procedure is in the form code, but I'm not certain. The same code worked fine when everything was all in the form code. The error reported when adding a watch to the Value property in the module function is "
'Value' is not declared. It may be inaccessible due to its protection level ". I have tried the following to no avail:
1) Setting the NumerciUpDown modifier to Public
2) Adding a Public ReadOnly Property to the form class that simply returns the Value propety of the NumericUpDown
3) Adding Imports Root Namespace.Investigator to the module
I am considering adding a Public Shared variable to hold the curent value of the NumericUpDown and referencing that from the Predicate of T function.I realise, and have read many times, that accessing form control properties from module functions is generally not seen as a smart thing to be doing, but since I am not trying to chnage anything, I simply want to know what the current value is I decided that I wasn't too worried.

I guess this is a general question say I have created a taskpanel class and I have text space in a footer I created. How would I refer to say a button that may or may not have been put on their at design time. I have code like this:-Private Sub Button1_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim rv As String
rv = ToolTip1.GetToolTip(Button1)
BorderContainerGood1._BorderDetails.footerDetails.Text = rv

I have a form set up where I want to run the function PopulateGrid on it's Form_Load event. I have initialized the DB connection as follows:
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadConfigFile()
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & config("DatabasePath") & ";")
cn.Open()
End Sub
Now, I want to run the PopulateGrid function directly after I connect to the database as shown above. I'm confused as to how I'd use a database query in a module when the database is initialized in my main form. Would simple setting the variable cn to public work?

I simply cannot refer to a control on a form from module code as in all other versions of VB. Here is the code that I mean:[code]The fact that this cannot seemingly be done without getting into looping through an array of controls, assigning the control to a general control variable etc. and much more guff is puzzling and is in my opinion an added complexity to Visual Basic. There must be a simple way to do this - I just want to refer to the value in a control, on a form, from a module.

Is there a way to add a property to System.Windows.Form.Control base class without defining the new inherited class (in VB.NET) ?
I want to add a Tooltip property to all of System.Windows.Form.Control controls, which will be browsable in properties window of that control.

the project uses a submain as startup object which is located in a module, thy so the application will be started in tray. Within the main() event i need to deserialize a xml file and with it set the properties of a class and then set what the application will do.The problem is, after I deserialize it and put set the property values I try to get them in the same event(main) but when it gets the value it returns as nothing(if string) or 0(if integer) but in the debugging i saw it setting the values.Is there a way to do that, within the main() event of a module to set the properties of a class and then get them without being nothing/0 ?

I'm trying to edit the text of a toolstripstatuslabel from a module in my project, but whatever I do, I can't change it. [code]But that didn't work either.I tried to change If Me.StatusStrip1.InvokeRequired Then to If Me.InvokeRequired Then, but that didn't help either. I also tried to change the modifiers property of the toolstripstatuslabel to public, with no result.

I have an 100 aspx files with one module file for code. All these aspx files have the same backend function, so i created on public module for all these files to access. These files are in the same folder. But for some reason the aspx files cannot access the function from that module.
mod1.vb Code (.vb file)
Public Module Allinone
Sub Allinone_Load(ByRef Page As Web.UI.Page)

I am at a roadblock of why the aspx files wont read this module? Also all these files are in the same directory

I have a console application consisting of two modules. One module named "quote" is the main module for the application. Another module named "common" contains commonly used functions and subroutines that are shared between multiple applications.
In the "common" module is a function named "quote". If I attempt to call the "quote" function from the module named "quote", then I get the following error: Error 1 'quote' is a type and cannot be used as an expression. However, if I copy the quote function from the "common" module to the "quote" module, then I no longer receive this error.
There shouldn't be an issue with calling a function that happens to have the same name as a module, but only when that function is located in a different module.

I've written a series of ASP.NET pages which have several common methods among them. In my ignorance, the best way I was able to find to move those common methods to a separate file was in a Module. However, what I need is a way to identify from which page was the method called?For example, I have a method call WriteToErrorLog with the following signature:WriteToErrorLog(ByVal sender As Page, ByVal Source As String, ByVal Message As String, ByVal StackTrace As String)

i started with 1 solution, 1 project a usual. Then i did it again, different project. Then, i wanted to have the 2 projects in 1 solution - so i copyed the project folder from solution 2 into the folder of solution 1 and added as existing project the project 2. So far so good.
Now i have a module with some public functions in project 2, that i want to use in project 1 as well. So i added to the solution a class module (some classes i want to share also) and i moved the module, (that i want to commonly use) into this class library. But it seems wrong - my application does not find the function again.

I have a situation where I have several VB.NET Modules in the same Logical-Module of a large application. I would like the update function of each module to be public, but I would like users to be forced to qualify the function call with the module name.
ModuleName.Update()
instead of
Update()
Is this possible?

I have an application (app.exe) that has a VB Module in its source code (Module1). The module has a function called Function1. I need to call this function from another application. The module is not marked as public, so adding a reference to app.exe won't work. I'm trying to use reflection (Assembly.LoadFrom()) but unless I'm way off base, the module would have to be a class in order for me to get an instance of it.
Please nobody ask me "what have you tried?" I tried a million different things and let's just say "none of them work." So I'm looking for someone that has specific experience with doing exactly what I'm trying to do. If you don't have that experience, please move on to the next question and ignore mine.
