I have to create a new project and in that project I have to create a inherited form from an older project. When I choose an inherited form, it says that I only can choose a dll file. But in my older project there is only an exe file. In all subfolders I cannot find a dll file. Can anyone help me to create a dll file for the older project so I can inherit that file in the new project.

How to create a class which inherits from a data type, specifically from Char data type? I just want to add one property to it. If it's not possible, are there any other ways to accomplish this?
View 2 RepliesIs the only way to create custom exceptions to inherit from System.Exception?
I wish to create a class that can be thrown as an exception but i do not wish to inherit from System.Exception because i have a base [Object] class in my library which all my classes should inherit from and i wish my custom exception class could also inherit from it.
I have a form that I inherit from.This form has some event actions like "load".Is there away to get the inherit child form to run that event on itself instead of the parent form.For example if I have frmTemplate.Load and frmChild.Load. The actions inside of frmTemplate.Load should be ran on frmChild changing any references to frmTemplate to frmChild.

I am cleaning up some code and I have multiple classes that are 99% exactly the same. So my understanding is that my options are...
1. Create a class and all other classes inherit from it and modify it a bit
2. Create an abstract class and all classes inherit from it and modify a bit ** I took this route
3. Create an interface and all classes Implement that interface.
Here is my 'original' class below (the one that all of them look 99% identical). This class is used in an arraylist so I have a listing of all my images from a folder I have searched.

I have an error that keeps regenerating when the form is closed and open back up.
1) Windows Form Application (Project: TestProject)
2) Add class in same project:
Public Class Test : Inherits System.Windows.Forms.TextBox
3) Drag and drop into the form within the project (works fine)
4) Close form
5) Re-open form... then error about the class Test in the project not defined
Actual Error: Type 'TestProject.Test' is not defined.
Is there a best way around this besides creating a separate project and putting the 'Test' class in that separate project and referring that separate project in the 'TestProject'?
Modified Added: By the way... i've used Global.TestProject.Test... but then again another error generate with the custom property within the 'Test' class.
I'm creating what I believe is an mdi app.I have a login form.I have a class for security.My login form creates an instance of the security class. There are all kinds of security parameters for each user (permissions to different things, etc.)These parameters are part of my security class.Once the user logs in, many other forms will all be opened and closed within the main mdi frame.All of these other forms need the information of the security class to know what the user has permission to do.Do I have to create a new instance of security class for every form in my project? Isn't there a way to store this stuff globally somehow. Retrieve once from the db at the start of the app during login and just get it from this global area everytime?

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

Added some controls. Build it, add the .DLL as reference to my other project.

The events from aaMyForm execute correctly but the controls added to it are not shown on XForm. I have found some info about set Modifiers Protected in order to be able to change the functionality of the controls but havent found anything about why the controls aren display on the XForm.
I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.
I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?

how to create a new project from an existing project?
I have a solution with several projects most of which are code or control libraries. I have a main windows forms application that references and uses these libraries. What i am trying to do is create a 2nd windows application that extends the main one, but i would like to be able to deploy them as separate exe's.
When i try to add a reference to the new app referencing the main app; all seems fine until i try to run the new app i get several error msgs similar to below:
Error 1 Could not find file 'ADODB.dll' referenced by assembly 'D:Visual Studio 2005ProjectsXXXinDebugXXX.exe.manifest'. <newAppName>
i have tried adding references to all the dll's in the error messages and they are still listed when i try to run the new app. I thought of a few work arounds but they require user changes to maintain separate exe's at deployment. I would like to avoid this if possible.
I am using VS 2008 and I have a solution with multiple projects. I would like to know how to open a form in project B from a Form in project A. The solution starts with the form in project A.I have tried the following and it does not produce the expected behaviour:In Form A I have added a reference to the Project B. The following code is in a form in project A. appraisal is a form in project B.
Dim appraisalForm As New appraisalApp.appraisal
appraisalForm.Show()
The above solution works to a degree. As the form is instantiated in Project A, I cannot reference any of the items in the form in Project B as I could if the Form in project B was instatiated through startup.
I have a number of projects in a solution and want to be able to access forms in all of the projects from a form in the main project. I thought of doing this to keep each segment of the solution manageble. If something goes seriously wrong in one of the projects it is easier to fix that starting from scratch with the whole solution.I have found numerous suggestions on this topic from "It cannot be done" to suggestions that do not work. The closest that I have come and still does not work is as follows:
Imports VAT_List.Form1 'This is Form1 in Project 2
Public Class Form1 ' This is Form1 in the Main Project
Private Sub ListsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListsToolStripMenuItem.Click
'Imports VAT_List.Form1

How to add an existing form of old project to a new project? Which extension type files to be added to work that existing form correctly?
I actually need frmContacts.vb (because a lot of textboxes and other controls are there) which I have added. Since it doesn't show any existing controls on form, I added other following files as well.
1) frmContacts.vb
2) frmContacts.Designer.vb
3) frmContacts.Designer.vb

These 2 added programs in essence create a PDF2TIFF converter using GS. I wish to call that form and use it as a utility from my main program. After reading other answers in the forum, I added these two programs as references in the main program and imported everything available, into the main program. I have what seems to be a correct build order set up. I want to open the form in the utility project(s) from a link on my main form. I tried a few things but the only way I could write the code without errors was to instantiate the second program then call that with a button click.

View 3 RepliesI'm currently working on building a program that will take a MS Access database system produced by my company and create a VB.Net project with all the forms in it (obviously the code should be manually done, but to save time the forms and controls can be produced automatically).I have tried Googling and seem not to be able to find anything about this (which probably means I wasn't searching with the right keywords), I was wondering whether anyone knows any good resources on how to create the VB.Net project programmatically as I already know how to do all the access stuff.
View 1 RepliesCreate a project that contains a Pet class. Each object will contain pet name, animal type, breed and color. The form should contain text boxes to enter the information for the pets. A button or menu item should display the pet information on a separate form. Hint: Use a ReadOnly property on the input form to pass the object to the second form.
What I have done so far is create a new class with the name Pet and have instantiated each object with readonly property. I have also created another form where the information entered by the user will be displayed. Guess I kinda need to know what would be the next step? And I want to ensure what I have done so far is correct.
