I have a bound datagridview that contains columns that have a start and an end time for each day of the week (column1 = M Start, column2 = M End etc) If the user enters 9pm - 5pm twice for Monday, I want a messagebox to pop up asking if they are sure they want to overlap timespans for Monday.

in a program I'm writing I'm creating some objects with a start date (with a datepicker) and an end date (also with a datepicker).
Now I need to check if this object's date range overlaps with any other object's date range stored in the database. If it does I can't save it in the database but if it doesn't I can.

I have a map of the world which is set as a background image of a form. I then have individual countries in red and green which appear based on the result of a ping request. So if the IP address pings ok the country turns green, if the ping fails then it turns red. The individual red and green countries are picture boxes with transparent backgrounds.The problem is that, for example, America and Mexico overlap each other and where they overlap it just show the background of the form. Can I have the picture boxes overlap but show each other underneath?See the image below for what I mean as it's not easy to say what I mean [URL]

I copied the exe file over to another computer and Im having an issue where the program will load and look OK but then after about 5 seconds part of the background will show up in the top left corner.

I have two grids inside a TabItem and in the code-behind I want to be able to add controls to both grids and have all the controls visible at run-time. Currently at run-time the controls added to "Grid3" are not visible while he controls added to "Grid4" are visible.The overlapping grids have the same rows but a different set of columns.I'm trying to do this with two grids so that I can vary the number of controls I can add per row in the code-behind by adding the controls to one of the two grids.Here's the XML:
<Grid Name="TabControlGrid" Margin="20,171,0,70">
<TabControl >
<TabItem Header="Tab1" >[code].....
The controls in the XML are just place holders for the controls I am adding to the grids in the code-behind.
I am part of a group writing a program for scheduling purposes. In the program I must check to see if times are overlapping.Say an Instructor is in class 1/1/2011 3:00:00pm to 1/1/2011 4:00:00pm receive the Instructor and 1/1/2011 3:10:00pm to 1/1/2011 4:50:00pmThis should return True the instructor is overlapped.Of course the other side would be if the time started/ended before or after the original class.I've tried many different combination's of if statements similar to:
If (begTime <= s.BegTime AndAlso endTime <= s.BegTime) Or (begTime >= s.EndTime AndAlso endTime >= s.EndTime) Then
End If

View 2 RepliesI seem to be having an issue with my form's background overlapping.I have two forms. One form is called the "mainscreen" and the other form is a small bar at the bottom of the mainscreen form, which shows different labels on a set timer interval.Anyway, the mainscreen will soon have a system in which it also runs different screens on a set interval. However, I seem to be having issues with the mainscreen already. I have set it to load a background image, using this code:

View 2 RepliesI have a sub-procedure which I want to run a different process, depending on what is currently running. I thought the easiest way to do this was by using an ArrayList of each of the campaign details & adding an 'Inuse' field to check to see if the Inuse field is set to 0 or 1. The problem that I have is that when running the process it is all happening at once & the integer hasn't been changed before the next thread kicks in so my threads are running the same campaigns. I tried to avoid the problem by adding a Thread.Sleep(100) delay inbetween starting threads but this led to exactly the same problem.
Here's an example of what I am trying to do:
Imports System.Threading
Public Class Form1
Private Campaigns As New ArrayList
Private ProcessRunning As Boolean = False
Friend StopProcess As Boolean = False
[Code] .....
Multi-Threading. I have got a simple bit of code that will need to be repeated but with a chance of it overlapping the only complex bit is there will be a varible that will be different each time. so I was wondering if I put it in another Thread and store the varible within the thread code would that achieve what I am looking for? To make it slightly easyier once the thread is started and pulled the Varible in there will be no cross talking between the thread and main app thread (ie no progress reports, no aborts/suspends etc) Nothing will be feeding back on thread completion either, when it ends it ends.
This is what I have so far:
Imports System.IO

I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))

If the item is blank and no data is entered it will throw a null exception, so the question is that how can I check if the item is null or not? Even using this:

Will throw the exception!
