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?
My program has 2 project. One project has parent form, another project has child forms.My program has to get form name as a string from database, and then call the child form depends on the form name.
For 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.
Is there a way in Visual Studio (2008 or 2010, don't care right now which one) to show all warnings and/or messages in a project?Currently, I see all warnings and messages for all open files/documents. It would be handy if I could switch an option somewhere or something to show all the warnings and messages without needing to open everything.(I ask this as I'm developing a web site in VS that I have inherited from an ex-colleague and there's lots of messages per page regarding outdated attributes and the like)
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.

I'm new in .Net and I have an application with windows form "LOGIN" When users enter the user and password and click "ok", then if user passes validation then I have the code Show(MDIMainMenu) (I'm trying to open an mdi form), but I receive the following error: "Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling Show. Error Number 5"
I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code: Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
Im trying to create a stopwatch in one form and another form show my progress bar using a combo box for mins and seconds to show the progress bar on form1 1
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub
Private Sub ShowDropDown() Using f As New DropDownForm f.Visible = True Do While f.Visible Application.DoEvents()
[Code]...
This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.
Iam creating an application. i have a main form it has 5 buttons i have created 5 more forms. my aim is to show a particular form for every button the form is opened in a new window i dont want to open in a new window it should be embed in the main form when i click anthor button it will show the related form in place of previous form

How would I change it so that it only closes the current form while opening a new one? EDIT: I put [Not Resolved] Because I accidently pressed the resolved thing
Im doing this project but u have a problem. im trying to make it so that when a timer in the first form(form1) ticks a progress bar in the other form goes up by 1.
I 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.
i used to write the code to show another form and unload the current form it always told error on UNLOAD form2.show unload me Do i have to use the code :
I have a series of methods being called for my networking code. An event gets fired from the networking thread. Inside this event, which I've hooked into from a singleton class, I route messages to form level methods which they register on form load to handle certain messages they care about. Inside of these form message hooks I need to close the current form (which I was able to do) but also show a different one (which is giving me the trouble).
I want to use a form in vb.net 2010, so when I click on a button ,it must show me the info of a specific row in Exel and display info of that row in a text box.
