VB 2005 Add A Form To DLL And Keep It Private To The Dll?
Apr 24, 2010
I am wondering if there is a way that I can add a form to my DLL and keep it private to the dll? I have a class which handles communication. I would like to be able to call a status form that would have a progress bar on it to show the status of a file upload and perhaps a form for handling comm settings.
The class is public with several public methods and properties but I do not want the form to be available outside the DLL. When I add a form to the project it is set to public and when I change it to private it tells me it must be inside another class.btw any methods used must be supported by CF V2 as this will be ran on Mobile devices.

I've read that modules are basically shared classes. For a module though, you can call a method directly without prefixing the module name. So I can do this: methodTest("abc", mod1Enum.enum2)But for a class with shared members I have to fully qualify the method call, and in this case fully qualify the enum:[code]In our conversion from VB6 to .NET the need to fully qualify all calls like this might be an argument for us to bring our VB6 modules over as modules instead of converting them to classes.

I am trying to access the controls' properties on another form without having to modify the code of the other projec (the one containing the controls that I want to access) because it is already compiled as a DLL. In this DLL that I am trying to access, the functions/sub-procedures are all declared as private. Would there be any way of accessing the controls' properties without having to modify the DLL? Basically what I am trying to do is create a sort of console application wrapper for the DLL that would create a new instance of the DLL's form and then make certain checkboxes checked and click certain buttons. Basically, I am trying to automate the form as it currently exists.

How to access a variable that is located in a private sub and then display that variable in another private sub located on the same form.
My actual code is:
Public Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
Dim strFileName As String
strFileName = OpenFD.FileName
OpenFD.InitialDirectory = _
[Code] .....
Obviously, the sub in blue has nothing in it currently and so this is the one I would like to access the variable in. The variable I want to use again is 'FILE_NAME'.

I was wondering if there is a way to remove "private subs" from a form. Many times I double-click the wrong button in the form, and that sub which pops up will stay in the code forever, which is making the code more messy.
Another thing is that if I change the name of a button in the buttons properties, the "Private sub button1_click..." in the code will always have the old name. Is there any way to update this name in the code?

I'm attempting to copy a rather complex form from one part of my project and use it (modified) within another part (ie, depending on whether it's maintenance or an outage, you'll get a slightly different email screen).
My first attempt failed miserably, as I had simply right-clicked and pasted the form within the project, assuming renaming the controls would work. nope, I didn't realise that there was stuff in the original form that was renamed as well, and that created a monstrous pile of errors.My second through fourth attempts also failed, generating errors in forms that (I thought) weren't related or connected. Once I deleted the copied form, all was fine.
So, short of trying to rebuild the form from scratch (using a different naming convention for my controls etc.), is there a simple way of doing this? This seems to be such a simple task, but alas I was wrong....(or, at least it's not easy with the information I have right now.

I have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.

I have been creating a call management application and I am having a problem with something that I have spent weeks on trying to get working and nothing I try is working for me. My application is an MDI application written in VB.NET 2005 Professional, using .NET Framework 2.0. It uses a back end database using Microsoft SQL Server 2005.When the MDI application launches, a form is displayed to the end user asking for phone number (MaskedTextBox) and a partner name. The partner names are within a ComboBox.
When the end user types in the phone number and selects a value from within the ComboBox, s/he clicks on the start button. This then opens a second form. The phone number from the MaskedTextBox is to default in a second MaskedTextBox (this I am able to get working without issue.) The partner name selected from the ComboBox is to default on the second ComboBox. This is the part where I have been working on it for weeks and not able to get it to function.
The second form has many ComboBoxes, all of which pull down items from a particular table within the database. Some of them are editable and some are not. The ones that are editable are also auto complete Suggest/Append on the ListItems.I wrote a sub to handle the population of these ComboBoxes and also to handle if they are editable or not. All of this is working. However, my main issue is that I can't get the value on the second form to default to what ever was selected on the first form. I do not get any errors but regardless of what I do, the second form always stays as the first item in the list regardless.
The code I am using is as follows:
<CLSCompliant(True)> Public Sub PopulateDropDownListFromDB(ByVal cboName As Elegant.Ui.ComboBox, _
ByVal TableName As String, ByVal ColumnName As String, _
ByVal UseAutoComplete As Boolean, _
ByVal UseSQLDistinct As Boolean)

I have two forms. Form1 and Form2. The user is supposed to fill out some information in form2 which then will be used to compute some data in form1. However when I used the code, Form2.Show, within a function in form1, the form2 is diplayed but when the user fills the data and submits them using the ok button, the code does not return back to the function in Form1.

My project has a single dataset with about 6 datatables. Each of those datatables has a TableAdapater and a Bindingsource on the main form (due to various databound controls).
Now, I want to have a second form for adding a new record. If I bind the controls to the datasource it creates new TableAdapaters and new Bindingsources on that form. I was wondering if it's possible to simply use the ones from the main form instead like this

I am pretty new to VB.Net and OOP in general and am picking stuff up every day, but it is so easy to become burnt out with the sheer amount of info. Therefore I am taking it slowly. Yesterday I was reading my book and read that using Dim for class level variables is allowed(if the compiler is set so) but is bad design and I should instead use Private. Dim defaults to private anyway. So my question is where should I use Dim instead of Private?

Imports System.Data
Imports System.Data.OleDb
Public Class Form1
Dim con As OleDbConnection
Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
