I've got a small reminder application I wrote in VB Express 2008. The main app autostarts with Windows and sits in the system tray all the time. Now, I need to save the time (sorta timestamp) it closes/terminates to a file. It works fine when the app is terminated by myself but doesn't when when I shutdown/reboot Windows. The code that saves the timestamp to a file resides in FormClosing event. But for some reason it doesn't fire or the code to save the file doesn't get executed when I shut down/reboot windows.
Is there a way, probably thru' Win API to register my app with Windows, so that windows actually waits for my app to terminate in a sane way after saving the data. I remember of reading about this possibility somewhere, I don't remember now.
I have an MDI web browser and it would be handy if it could save the open MDI childs at shut-down so that the next time the user would open the web browser the MDI childs would be still there...
Is that even possible?Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Alright im trying to make it where in Visual Basic 2008 you click on a box ether 10, 20, or 30. Then that tells a timer that the program needs to turn off in 10, 20, or 30 minutes. What I basically want it to do is, whenever the set amount time is when it goes off it shows form1(login form). I have prepared a picture can anyone supply me with some information on how to do this?
I typically prompt the user to save changes in the FormClosing event in MDI children. The application updater uses a Process.CloseMainWindow call to close the application if it's running before the patch update is applied.
I need to detect when the updater is closing the application and NOT prompt the user to save changes but save them automatically. I've tried using the System.Windows.Forms.CloseReason but this method isn't working for me. I capture the CloseReason in the MDI Parent FormClosing event but it's called AFTER the MDI children are told to close. I tried capturing the CloseReason (e.CloseReason) in the MDI child's FormClosing event but it registers as MDI Parent closing and a normal application exit is also going to raise this same e.CloseReason so I can't auto-save here either.
So my question is: How can I detect this Process.CloseMainWindow being used to close my application so that I can bypass all save prompts and save automatically? What is the first event called in this method of closing so that I can signal all MDI children that are open in their FormClosing event to just save?
I have three tables under one database. I'm using the built-in Navigator control for now until I get this figured out, but I'm using a button command instead of the built in navigator button. I need the "Save" button to save the data in the text fill boxes to save to the corisponding table. I used the drag and drop option to drop rows from each table to the form. See code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e
New to vb.net coming from vba. I am working on a mass balance model which collects a handful of 'user' data (less than 10 records) and then applies various equations to the data and records/reports the resulting values. I think I have a pretty good handle on the basic operators for a single 'user', having pretty extensive vba knowledge. However, I am having difficulty saving the new 'user' data and creating new 'users'. I need to keep the app as simple as possible for deployment to machines with nothing more than 2.0 and I do not really need a database, just a simple method of creating multiple 'users' as objects.
I made my first app today. The point is to enter a password and then get into a screen that displays info, and you can edit it by typing in the text box. Is it possible to save the data typed?
I am sharing databinding when opening a detail form a summary form. The data is shared fine. What I don't know is how to save any data that may have changed, or to create a new record.[code]...
I would like to commit the data put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config, either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings. using my.mysettings, my.settings and my.settings.default. Thank you in advance for your input.
This first method is a called when a button is pushed. it checks the text and then calls the next method (AddProperty) which should add the property to my.settings and save it to user.config, but my understanding is that it is not written to the file till the applicatoin closes.
I wanna save the data present on the form to the text file.I am using vb.net for this. how can i write the text present on the form in the same formate (showing on the form) in the .txt file.
I need some general advice about using ListView. The program was originally written in VB2002, but now it's running in VB2008.The results of my program would typically be a ListView of 30 lines by 8 columns. I need to be able to save this data so that it persists after I close the program. There will never be a need to manipulate the data, so I'm looking for something simple. (There will be a need to print it.) I'm presuming that I need to link to a database to save the data. Correct? If so, can I use the one in Microsoft Works (which I already have), or do I need to get Microsoft Access, or is there some other better (simpler?) alternative?
I want to save data from web and desktop applications and then provide that info again to fill the forms with the saved data .I am using vs2008 and sql2005
how to reboot the PC from coding with VB.Net framework 2.0 or above.i also like to set timer for rebooting process.does VB.net framework support for above process? do i need to add library or DLL file
I'm using VS2008, targetting framework 3.5..Every time I reboot the PC, I open up Visual Studio, play with my code a bit, then hit F5 to debug it. I play around with my code some more, then debug again, and end up with the following problems:[code]The previous ten items in the error list are all Warnings, and they've all been in the project for forever, so I don't think they are the issue, here.What is the issue is that Visual Studio refuses delete/copy the XML file, and so will not run. I have to shut down the IDE to fix the issue.
I wrote a program that is a system tray app that has no user interface. The issue is that when you shutdown, log off, or restart the PC the app does not shutdown and the user has the "End Now" message box pop up.
The only thing running on this app is that it is listening to a port for communication.
I do not have any code in the form closing event as that is what I want just to close.
But after I start again navigate username still is there (website is keeping login for 15 minutes), I tried to dispose webbrowser but I can't find control to start it up.Webbrowser is invisible... how I can restart/reboot/clear cache on webbrowser ?
I set up some application settings for checkboxes on an app and then decided to remove them. When I set the Application Settings to (none) in the designer and restarted the app, the checkbox constantly checks and unchecks itself. I completely remade the app and removed the file that is used to store my.settings in the Local folder of the user's appdata profile. I also made sure to uncheck the "save my.settings" on shutdown.
how to code for the save button in vb.net datagrid view by using insert into sql and update sql statements (it should be able to insert & update the data grid and save the changes) when the save button is clicked .
Quite a few threads on passing data from one form to another, but I'm struggling to work out how to share data between the two - back and forth.
For example:
Class1 is a class with 10 string properties
Form1 has 10 labels ("Label1", "Label2" etc) and a [Configure] button. Form2 has 10 textboxes and a [Apply] button.
I want to load with Form1, and create an instance of Class1. Click the Configure button and load Form2, passing Class1. On Form2 I want to manually fill in the 10 textboxes and hit Apply. The Apply should update the Class1 instance and close the form.
Form1's Label controls should then be updated with the data from the Class1 instance.
I'm fine creating the forms and classes, as well as passing the class into Form2 with a custom Sub New(EmptyClass as Class1) constructor. This gets the empty class into Form2, but how can I get the populated class back to Form1?
As Form1 already exists I don't want to create a new instance with another custom Sub New(PopulatedClass as Class1)
It's also key to be able to use the Form2 multiple times, basically ending up with a Data class being displayed as part of Form1 but updated using Form2? (For example if the Class has already been created and populated with data when it's passed back to Form2 for the second time I would pre-load the Textboxes with the values already in the class).
in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.
Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs Public Message As String
[CODE]...
The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
how to save data (for example some text that user type [as password etc]) and save that password on same location where is application. After saving I want to have also Load option so we can load saved data.
I am re-doing part of a GUI for my project, The Windows Alias Generator, and decided to switch to MDI. The child forms consists only of RichTextBox1. Here's the generate routine called when the save is clicked:
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles SaveAsToolStripMenuItem.Click, SaveToolStripButton.Click Dim ActiveMDI As Form = Me.ActiveMdiChild[code].....
But because I cannot define richtextbox1.text from the currently active MDI, I cannot use this routine...my question is this: How would I get RichTextBox1.text from the save option in the MDI form?
I've written a very simple program that writes a tiny "config.cfg" (text) file to the computer (using StreamWriter), and a second program that is supposed to read that data back.
Unfortunately, it appears you can't save to the same folder as your program under Win7 ("Program Files (x86)" is a restricted folder.) So instead, VB automatically saves my data to the "C:Users(myname)AppDataRoaming..." folder. This is annoying, but tolerable.
PROBLEM IS: How does my second app then FIND my data file (without doing a time-wasting drive search every time the program is run?)
My code:
' Program #1: Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click Dim FileWriter As New StreamWriter("config.cfg")
