I have a method where I am making a trial period. When the date has exceded its trialperiod the program will not close.
The code looks like this:
Public Sub DemoRestrict()
If My.Settings.dteStartDate = Nothing Then
My.Settings.dteStartDate = Now
[CODE]...
Why does the form not close? is just runs to the next method in the load sequence
HTML
Public Partial Class WebForm1
Inherits System.Web.UI.Page
Public num1 As Double[code]...
This is a part of a calculator code. When you press the button "BtnAdd" the text in TxtRes is held by the global variable "num1" and the operation number (whether add or subtract) by "oper". My problem is : OUTPUT 1: prints num1 = 25 (for example)While OUTPUT 2: prints num1=0
Why is this happening ? Isn't the value of num1 supposed to be equal everywhere in the form at a given moment ?
I have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net
Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show(Me)
End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.
I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?

View 5 RepliesI have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.

I'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.

I have a VB.Net project that I haven't worked on in awhile. I got into this morning and started to run it. I got some errors so I decided to step thru the code. I enter the Page_Load event of a Form module and execute a function call and it takes me to a "End Function" statement. Totally bypasses the function that was called. I continued to step thru it and it just took me randomly thru code. No order whatsoever. I believe I've had this happen before but don't recall how I fixed it.
View 5 RepliesI'm having lots of trouble understanding how repeaters are supposed to work and how I'm supposed to use them. Basically, I have a label, a set of image buttons, and a div within a repeater. When you click on the button, I want to populate the div that was created with these repeaters (so a different div for each iteration of the repeater).[code]I can't get the repeater to iterate. It's only firing off once and then stops. I can't get a label with the repeater data source's Subject (a field in my database) to appear.

I was playing around with designing a custom interface for a test application and I am using a custom image for a close button. I am using the FlatStyle properties to define it's look'n'feel. I've set the border to 0 but when the application loses focus, the border of the button shows up.I have tried to force the property to go 0 again when the application's "LostFocus" event is captured but doesn't work.I am also using a "rollover" method using MouseHover and MouseLeave events to change the image of the button.Using Visual Basic 2008 Express Edition.

in the form if i put a value in for owed = 30.00 and paid 34.25 my dollars returned = 4 and that is correct but the number of qtrs = 0 and should be 1. I am not sure how to correctly use this - any assistance you can provide is great - this is purely educational

I am writing a GUI application to run on a touchscreen device using VB.NET and WPF--it must be full screen at all times, like a kiosk app; the window must not be able to resize or move in any way. The window contains a ListBox that users can currently scroll through by dragging across the list. The problem I'm seeing is that when the user drags across the list, the whole window moves a bit, exposing the desktop underneath, then springs back into place once the user stops dragging. I have not been able to figure out how to keep the window stationary while still allowing users to drag across the ListBox to view all list items. Here is a somewhat simplified version of my code:
