View 2 RepliesI need to calculate the location of intersections between multiple date ranges, and the number of overlapping intersections. Then I need to show which date/time ranges overlap each of those intersecting sections. It is slightly more complicated than that so I'll do my best to explain by providing an example. I am working in VB.Net, but C# examples are acceptable as well as I work in both.
We have several high risk tasks that involve the same system. Below I have three example jobs named HR1/2/3/4 with start and end date/times.
HR1 {1/6/2010 10:00 - 1/6/2010 15:00}

So I've gotten a lot of help from this forum for this incredibly large, incredibly pointless application I'm making right now.I need to be able to have people type in, say, the name of a city. Then it will display a table of Name / phone number.So I need a table that can change for each "city name", and can scroll down. I know I'll most likely have to save it to two variables for each "city", I'm already set up to do that. ( Variable Name, Variable Phone Number) What I don't know is how to... print the data into a table, or make two text boxes that will scroll simultaneously.If there is a way to attach a scroll-bar to two text boxes, that would be my preferred method. If I have to use a table, what would the substring and code look like to change:[code]

The purpose is that I do alot of work with remote control cars and need to acuratley set toe and camber angles, it takes to long with the "old" method So I am creating this little program. ok, so, lets see what I want to do. Well, the first thing I would like to do is draw a line from top to bottom of my picture box dead center of left to right, this is dead center of the cam so the bottom of your item should be posistioned to meet the bottom of the centre line. I then draw a line from bottom to top of the objects angle. I then use the dead center line and the line I drew to calculate the angle.

View 2 RepliesI am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.
