VS 2008 Binding NumericUpDown With Application Setting?
Jul 21, 2011
PROJECT TYPE: Windows Forms Application
LANGUAGE: Visual Basic
.NET VERSION: 3.5
IDE: Visual Studio 2008
OPTION STRICT: on
OPTION EXPLICIT: ON
I am attempting to get 7 NumericUpDowns to display the value of the application setting they are bound to. Each UpDown has its own setting binding. The setting is a decimal datatype with a value of either 4 or 6 as default. I need the UpDowns to display the setting value when the form loads. At the same time, I need any change made to the UpDowns to be saved to the same setting so that the application can both display and use the new value the next time it runs. Unfortunately, the only way I can get them to display anything other than "1" is to hardcode a constant value, and I don't want it to be constant. I think this is the last bug in my application and would love to get it figured out, but I've spent over 8 hours on it with no luck. Here is the applicable code.

I have created a user control tha inherits from the NumericUpDown Control.Is it possible to set the cursor position within the control?I am validating the text OnKeyUp, and formatting it when it meets certain criteria.To do this i have to do me.text = Fomatted(Me.Text), which sets the cursor back to the position 0, i want to set it to the end of the text area.

I have a class from where I need to set objects in another form?
Form1:
vb.net
Function SetMyObject(ByVal frmTarget As Object)
frmTarget.PictureBox1 = Form1.PictureBox1
End Function
(Not tested code, just wrote to show what I mean)So that's the late binding one.I should also say that the frmTarget variable isn't static so thats why I can't make something like Form2.PictureBox1 = Form1.PictureBox1

I'm using my.settings to save the load time of the solution. When my.settings.load_time value is changed and use my.settings.load_time.save() to save them. When I quit the application and manually start it again, the newly saved settings are used.
When I use either application.restart. The application will use the old values for my.settings.
My question is.. Is there a way to restart the application using either application.restart which will use the newly saved my.settings values?

I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?

An user is allowed to enter as well a value in the numericupdown box manually.. How to capture what he has entered?So far I have:
Private Sub NumericUpDown1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles NumAmount.ValueChanged
btnAdd_Click.ForeColor = Color.DimGray
If NumAmount.Value > 0 Then
[code]....
The above works also if I add a value manually and press enter... But according to the exercise it should directly notice a manually entered value without pressing enter. How to do that?

Does anyone know of a way have the PropertyGrid control display a NumericUpDown instead of a DropDown box or text box? One of the properties that I need to capture is an integer and I'd like the user to be able to spin up or down to choose a value instead of typing it in.

How can I bind a key combination to my vb.net application? I know it has SOMETHING to do with the registry, but I have no earthly idea what or how to go about doing this. I want the user to be able to hit those keys when the app is open and have it execute my function, but not while the app is closed.

I am a newbie using VB.net in VS 2008. I took over a vb.net winform application that has a binding navigator in it. The users wanted to add 2 new fields to the form. I added the new fields to the SQL Server 2005 database. I refreshed the Data Source tab in the project. It recognizes the 2 new fields.
I dragged them onto the form. When I go to add a record through the application, it does NOT save these 2 new fields. I check the properties for these 2 new fields under "Data Bindings" and it shows under the "Text" property the correct Binding Source and column name. I need to store these 2 new fields to the table.

I use the binding navigator in my application, but when the resolution of the display gets to small and I have to use the scrollbars, then I get a problem. The scrollbars automatically scrolls down below the navigator bar instead of showing it when the window loads. I figured it out using focus or select. it now loads on top,but then I got a second problem.When I press on my tab-control it "autoscrolls" down again and puts the tab-control as the first visible thing on the screen instead of the navigation bar. How can I prevent that?

I have created a little application to move some files around and put them into a database. This is working well except that the application needs a timeout. If my app has not completed the task within 2 hours it re opens and locks out everything. I need to say that if my application has been open for 2 hours close it. One thought was can you set a time out in an application.

In VB.NET, you can set focus to an external application using
AppActivate("Windows Name")
or
AppActivate(processID As Integer)
Now this works fine if you do for example:
Dim intNotePad As Integer = Shell("C:WINNTNotepad.exe",
AppWinStyle.MinimizedNoFocus)
AppActivate(intNotePad)
But when I do:
For Each theprocess As Process In processlist
If InStr(theprocess.ProcessName, "DWG") Then
strProcessList += String.Format("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id) + vbCrLf
AppActivate(theprocess.ID)
[code]....
then it doesn't find the window, even if it's open and even if it finds the window using the window title.But I need it by process ID.How can I do that?I need it to set focus on a 3rd party installer in a windows installer setup project.

I have an application that has two states based on the value of a Boolean variable: a read_only=true state and read_only=false state. The value of this state is stored in an external settings file. My application has a feature called deploy that generates a copy of itself in the same folder with the read_only=true state. But, the read_only variable value is stored in an external file so now both files will be in the read_only=true state. What I want to do is make one of them(the original one) always be read_only = false and the other read_only=true

I've tried everything to set my window as active after I've been working on another external App... I have my system on auto and need to send some keystrokes to the program using sendkeys, so I need that app active. I've tried almost everything I can think of, bringtofront, setfocus, windowstate, setactivewindow, setforegroundwindow (For the last 2, hwnd doesnt work - I'm using VB 2008 Express) but none of them seem to be working.

I want to make a simple quiz game like kbc in vb.net 2008, for that i have created five buttons in my vb application. and one table in sql as under
create table kbc
(
Question varchar(100),
Option1 varchar(100),
Option2 varchar(100),
Option3 varchar(100),
Option4 varchar(100),
Answer varchar(100)
)
And i have inserted these records in this table like this
insert kbc values('Largest key of ur pc is ','Enter','Backspace','Shift','Space','Space')
insert kbc values(2,'How many muscles are there in a human body ?','206','602','605','208','605')
Now back to my vb form the first button will catch the question and second,third,fourth,fifth buttons will catch options from sql database that i have shown. just as kbc i want to show one question with its four options. and when user click on any button i also want to check the right answer. right answer is also in my kbc table's Answer column. to do that i have written this code
Imports System.Data.OleDb
Imports System.Data
Imports System.Threading
Imports System.Data.SqlClient
[CODE]...
On all button's click i have declared temp variable to catch the last column's text from my sql table and then i want to match this text with the text of that button the user clicked. if texts match i want to go to the next question of my quiz program. how to do that working. but it is not working as i want.
