I'm using VS.NET 2005 PRO, On my most recent WINFORMS project when I try to add a second form to the project I get a pop up that says object reference not set to instance of object. This is coming directly from the add new item template box, not sure what's happening, never had this before,

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.
View 2 RepliesI 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

I am really new to Visual Studio and VB and I am having trouble closing a single form:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub
When I use Me.close() associated with this button it closes the entire project and not just the single form can anyone.

View 1 RepliesI have read a lot of the prior questions/answers on this topic but it only took me so far. I have a solution to which I added 2 additional programs. 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.

To start I already removed this form and created a new one, but I'm curious why this happened and what I did wrong.
1. I created a new project and copied several forms and files from an existing project using the "Add Existing Item" function.
2. I had one form that would show but had no data.
3. I call the form like this[code]...

View 2 RepliesI am working on the following scenario: I got an existing VB.net application. Now I have to add a login mechanism to it. What I want to do is, add another form to my project and show it before the 'real' form of the program is displayed, so that it can handle the login procedure.
View 3 RepliesIs there any specific way of calling the form of another application.My main project is a WPF application.From that it is calling another application is Vb.NET.. This is done by creating a process and then calling the exe.
Dim fp1 As New Process()
fp1.StartInfo = New ProcessStartInfo("Location of the exe")
fp1.Start()
Now the problem which I am facing is that from that exe I need to call a specific form in the WPF application.
I have a main form that i show at run-time (Form 1). While Form 1 is showing, I show another small (Form 2) form to provide the user with some additional options to chose from. You can see how I show this second form below in EXAMPLE 1. When the user is done with the second Form, I want to Hide it and return to the first form Form 1. However when the second form is hidden, it does not return me to the first form when I use the Show method for Form 1.
Note I am in development mode as I test this. When the second form hides, the first form stays collapsed at the bottom of my desktop. I can click on it and it will pop up and everything is fine. However, I cannot seem to get pleasing transition from Form 2 to Form 1 using the code in EXAMPLE 2. Note that I do not Hide Form 1 to begin with. I am assuming that this is why the Show method does not work. However I cannot figure out why it collapses in the first place. Is there a Focus property that I need to set for Form 1?
