View 2 RepliesUpdate Function Of Each Module To Be Public
Nov 2, 2009I 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?

Calling Function With Same Name As Module?
Sep 29, 2009I 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.
Calling A Function That's In A Module In External Application
May 25, 2012I 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.

Public Sub Label Changes On A Form Don't Work When Called From A Module?
Dec 15, 2009I am writing a control application for an inteface card. The complicated work of initialising communication with the card is written and working fine. However, my problem is to update the text in a dialog label on the communication interface form from a module that contains all the coding for accessing the inteface card. From the module, the interface dll returns data that describes some typical connection errors and the module then calls on Public Subs in the form to display error messages; for example:This is the Public Sub in the Module that initiates communication with the interface card:
Public Sub OpenDeviceInterface()
DeviceID = 1 - My.Resources.DeviceID
h = OpenDevice(DeviceID)
Select Case h
Case 0, 1, 2, 3
[code]....
What happens when these Public subs are called from the module is that the MSgBoxes I made to test the routine show up but the label text doesn't appear.I've tried; Refresh, on the label and the form without success...

VS 02/03 Calling A Form's Controls From A Module
Jun 10, 2011I'm writing a program in vb.net 2003 and have come up with a problem.
I have a sub SettingsSave() in a module.
Public Sub SettingsSave()
Dim frmSaveSettings As New frmSettings
MsgBox frmSaveSettings.txtName.Value 'for testing purposes
SaveSetting("MyApp", "configs", "Name",frmSaveSettings.txtName.Value)
SaveSetting("MyApp", "configs", "Pass",frmSaveSettings.txtPass.Value)
End Sub
I have a form frmSettings, which has a button btnSave. When the button is clicked, SettingsSave() is called.The problem is, if btnSave is clicked, then either of the two textbox values are changed, then btnSave is clicked again, the SettingsSave() sub still returns the 'old' values (from the first time the save button was clicked).How do I clear the old values from memory? I've tried adding frmSaveSettings = Nothing, and frmSaveSettings.Close at the end of the sub SettingsSave().

Is there something fundamental that I am missing. Is this where the "Friend Shared" comes into play?

Calling A Function / Assign Property Of An Object Inside An Array
Oct 5, 2010So if I create an object test, and it has a property color. When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able to let it know what type of object I am trying to work with inside the arraylist. In code maybe something like this

Public Function With Form Scope?
May 17, 2012I have a Function for checking the input in a textbox and only allowing Numeric & Backspace; everything works fine so far. My form is for financials and it has about 20 textboxes; they all receive Numeric only data; there is NO alpha data on the entire form required. Note in the snippet below that I don't even need a decimal point as well.
Is there a way to handle ALL textboxes on this form without having to place the Function call in each textbox KeyPress event. took a long (5 year) hiatus from developing VB6

Refering To A Form Control Property From A Module Function / Sub?
Mar 7, 2012I 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.
Calling A Function From Another Form?
Sep 2, 2011Is it advisable to call a function from another form?Does it have any side effects on the system while running, like more process will consume?I have a function that will set the background in a form, it will make the image stretch, backcolor transparent and will set the picture. If I will use that function in other 15 FORMS I can minimize my code.

Jun 26, 2011Version: visual basics 2008
Problem:
Form 1 contains a SWF object, which is called FlashGame (it has a movie set, which is a game)
Form 2 contains a button to set a variable on the FLashGame.
Example
Call FlashGame.SetVariable("variable will be here", 1)
That simple coding works when the button to call that SetVariable command is on the same form as the FlashGame, but I need them to be on different forms.
Database - Running SQL Query From Module With A Function Call From The Form?
Jan 28, 2010I 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?
