I usually can find anything I need on google, but this isn't the case this time. I have a com object that is a display control, it displays images from another software that are retrieved from a camera. I am trying to overlay graphics on this image for reference to an operator. I have found how make a picture box image transparent but not over another object. The images are PNG and are set to transparent.
View 12 RepliesI'm doing a new interface for my app and I'm using MDI forms. On the parent form I want some objects like Labels and ToolStrips with Transparent BackColor but even when I change the MDI Client BackColor to Color.Whatever or the BackgroundImage and apply a Transparent Object it just doesn't get the color behind it but gets DarkGray instead .
I changed the MDIClient.BackColor with: Me.Controls.OfType(Of MdiClient).First().BackColor = Color.Red
I have a form that displays data. What I would like to have is a button that when pressed will display some test extran textboxes in a dimmed/transparent type of fashion. I can get that using another form, but would like to do it without the second form.

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]
View 7 Repliesin 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).

I have a vb app that I completed a few months ago and it has been working as it should.I have blurred out part of the image for business reasons. But you can see in the second picture in the top left it has the bottom right of the background overlapping in it.
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. Im not sure why. It is the exact same exe on the other computer but it only does it on this computer.I have attached images below so you can see what Im talking about.Im not sure if its a program issue or a setting on my computer.
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.

View 1 RepliesI 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 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*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))

I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?
[Code]...
long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.
