I want to add a close button to a custom navigator. That's fine.
Now what if I want to use it on every form that I would create ? What is the best way (Is subclassing possible for this control in that case, ...) ? Any inspiring code somewhere even for another type of control ?
One of the VBF member was asking how to add a close button on the BindingNavigator control once and reuse it on all other forms, so I try to create a custom bindingnavigator class that inherits the BindingNavigator class.Below is the inherited class:
[Code]...
The thing that I can't figure out is that it looks OK in design mode, but at run time, the custom binding navigator shows 2 "Close" buttons. Only one of them will close the form when clicked, the other one doesn't function. See the attached image.
I have a GDI+ question using Aeonhack's themebase. I'm using Aeonhack's themebase in VB.NET to make my first theme. I want to make the theme so that there is an X (close) button at the top right corner built into the theme. I'm doing so like this: [Code] And when I run it, it works fine. However, when I run it with that code, my buttons "disappear" or rather, turn that blank color you get as the control background for a forms application. How can I keep my buttons from doing this?
View 6 RepliesOk what I am working is creating a tabpage at run time, I ahve a class that inherits tabpage class and when I call, it creates a new tabpage and add it to the tabControl, My codes are as:
Class CreatenewTab : Inherits System.Windows.Forms.TabPage
'Some implementation here
end Class
[code]....
How to make a new created tab to be selected and top? I have tried .show(), .Select() and .Focus() but nothing happens. What I mean is when you click on add new Tab, like in Browser a new tab is created and is selected for use(become top)
this might seem a fairly stupid question to ask, but how do you use a Button to close all forms and end a Program?

I am trying to work on an application that disables the close button (X) on the upper right hand corner of a window. In order to do that I need to use calls to API methods like GetSystemMenu, EnableMenuItem and RemoveMenu. I can figure out how these methods work but there are certain parameters that these methods have whose values that need to be passed to them as argument is unknown to me. How can I know them.
E.G.- for EnableMenuItem, the parameters are- hMenu (handle to the menu), uIDEnableItem (The menu item to be enabled, disabled, or grayed), uEnable (This parameter must be a combination of at least two of the following: MF_BYCOMMAND or MF_BYPOSITION MF_ENABLED, MF_DISABLED, or MF_GRAYED)Now when I call this method from my application I supply the current window handle as the first argument, the item no. to be disabled/enabled as the second argument but I CAN'T UNDERSTAND WHAT TO SEND AS THE THIRD ARGUMENT. What exactly are the possible values for those parameters- MF_BYCOMMAND or MF_DISABLED. I checked certain examples where they are supplying hexadecimal values like &HF060, &H1, 0x400, 0x1000, 0x2 etc. or integer values like 1024, 2 etc. But how would I know what exactly these values are and when to use which value.The same problem arises in case of calling RemoveMenu method.
ust want to know a better way to remove the close "x" button of the form, or atleast every time i close it end up openning again.
View 5 RepliesI'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.
View 2 RepliesIs there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.

For instance, if a user is adding a member I want to disable the Delete button and all of the Move arrows, plus the ability to change the Position number.The same applies to clicking the Delete button. Diable the Add & Move buttons, etc.I tried BindingNavigatorMoveFirstItem.Enabled = False but that has no affect that I can see. I can still click the movefirst arrow and move away.

View 1 RepliesI have an application built that has several forms. I use an XML file to store settings data (mainly folder names for data output) and I need each form to be able to access and modify the data. I'd also like each form to access functions from a main form (such as file parsing functions). I have read articles about properties and inheritance but I need some guidance as this topic is pretty confusing.

I am working with several RFID readers that perform different function in my vb.net program. Currently each reader port number is hard coded into the respective form. For example, reader 3 operates on COM1. However, this will be problematic when installing on different machines.
What I would like to do is have a "configuration" form where the user can select each reader and then select the COM port. Then all other code references these settings. What would be the best approach for this.
The only way I know to do it currently is to place this information in a small database and then have the forms reference that database, but it is a lot to do for such a seemingly trivial task.
I have some icons and images that are stored as embedded resources in my form1.resx file. Is there any way I can access these resources from my Form2 without adding the icons as project resources?

I am trying to figure out how to seperate my business logic from my forms. This is my first attempt at doing this, but I would like to figure out how to handle events from multiple forms within a class. I have found myself routinely writing the same logic over and over in each form class and its time I figure out how to completly seperate out that logic in winforms so I can reuse the methods across all of my forms.
So basically I have this click event in form1:
Private Sub btnSubmit_Click(sender As System.Object, e As System.EventArgs) Handles btnSubmit.Click

When I declare a variable as public, shouldn't it be available in another form?

I intend to then assign a mileage based on the two points and write to file on mobile device. We support 12 schools, and I want my employees to track mileage easily.
Public Class main

View 12 RepliesIn a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

View 2 RepliesI need to share variables across two forms in vb.net. One of them is the main form and the other is a child form.
Create a static/shared variable in one of the forms and access it in the other forms via:
Form1 frm = new Form1(); //creating object of parent to access shared variable
frm.a = "abc"; // passing value
Send an instance of the main form to the child form when creating the child form. The variables can then be accessed via a property function. Create global variables in a module. This seems like the easiest option, but I doubt it is the best option.I also read something about delegates and events, but I don't know how to implement this.
What I mean is that when I make queries on a Parent Form. Child forms can also retrieves the datatable /datarows from its parent form.

I'm starting to put in a database into my application, however I'm drawing a blank on how to share a database connection among the dozen or so different forms in my MDI application. I'm assuming this has to do with interfaces or something but I can't find any relevant examples anywhere. Can someone help me out? Ideally what I'd like is when the app is loaded up there is a call to a function in the forms loading area which establishes a single connection to the mdb, that I can then call via any form so I don't always have to open/close connections everytime I need to update the db?
Here's a basic example of the mdb database access code I've got working:
Dim dt As DataTable = New DataTable()
Dim OleDbTran As OleDbTransaction = Nothing
Using connJET As OleDbConnection = New OleDbConnection("connection string here...")
