View 5 RepliesResponse.ContentLength Property?
Mar 2, 2009If you run this code, builder.Append("Content length: " & response.ContentLength & _" bytes" & vbCrLf)
it returns a string builder object which shows the number of bytes contained in the page. But the url here must exceed some sort of character limit because it is returning -1 as the value which means (Unknown?)
Dim uri As New Uri("http:raws.wrh.noaa.gov/cgi-bin/roman/raws_ca_monitor.cgi?state=NWCC&rawsflag=2")
Dim builder As New StringBuilder
builder.Append("AbsolutePath: " & uri.AbsolutePath & vbCrLf)
builder.Append("AbsoluteUri: " & uri.AbsoluteUri & vbCrLf)
builder.Append("Host: " & uri.Host & vbCrLf)

Battery Life Time - Measurement In Seconds Or Hours
Jan 28, 2011Searching about kernel32.dll and battery functions in it, I came across some interesting
Public BatteryLifeTime As System.UInt32
The full declaration is:
Private Declare Auto Function GetSystemPowerStatus Lib "kernel32.dll" ( _
ByRef lpSystemPowerStatus As SYSTEM_POWER_STATUS) _
As Integer
Private Structure SYSTEM_POWER_STATUS
Public BatteryLifeTime As System.UInt32
What I don't understand is, what measurement do the "BatteryLifeTime As System.UInt32" is in? I mean, is the Battery life Time in seconds or hours.. Or something else, so how can I convert it to something I can use..

View 8 RepliesMaking A Units Converter?
Sep 22, 2011So i decided to make a units converter for my term's project and my teacher insisted on including the combo box in this project. I'm not really familiar with the combo box as i am still a beginner in visual basic. I've looked around and learned a bit about using the combo box but later i faced a problem. First i created a Main combo box and placed it in the middle of the form. I managed to use the select case command to make other combo boxes appear and disappear as i wish. I don't really know how to describe the problem, i want to make it that if i choose the input as a unit and the output is any other unit from two different combo boxes, the value in the input text box would be multiplied by a certain conversion factor and the result will be shown in the output text box

- number to be converted(text box)
-unit number is in(combo box)
-unit to convert to(combo box)
i know how to do combo boxes,buttons and labels and stuff.The output is the converted number this is what i have so far but its soooo wrong?

[2008] Finding Distance Between Unevenly Spaced Units?
Jan 23, 2009I'm trying to write a little program to help me find the distance (in feet/inches) between the frames of a ship. This would be fairly easy, except the frames are unevenly spaced.Let's say this is a top view of a shape, and the frames are vertical lines that comprise the overall ship. (In ships, this is the shape of the hull.) Each number is a frame.
1 2 3 4 5 6 7 8 9 10 11 12 13
In this example, there are 1 units between frames 1-3, two units between frames 3-6, three units between 6-9, four units between 9-11, and 1 unit between 11-13.So, what I want to do is post a program where the user inputs two frame numbers: so they would enter, for instance, a start location of 5 and an end location of 11. So, it would calculate the number of units between those two frames based on the limits. So, between 3-6 there are two units, so it would subtract the start location from the nearest limit (6).
6-5 = 1
Multiply by 2 units spacing per frame, so that's 2 units. Frames 6-9 are all included, so 9-6=3 x 3 units = 9 units. Since 9-11 are also all included, it would be 11 - 9 = 2 x 4 units = 8 units. Then the program would add that all together - 2 + 9 + 8 = 19 units total.
Now, for my instance, there are a few more complications (it's in inches, and large increments (i.e. 36" spacing), and there are 304 total frames split between the middle of the ship in two sections, fore and aft of the line), but really I'm just trying to get a handle on how to impose these limits and calculate the distance. Attached is the proposed layout for my program (ignore the 20'5", that's just how I want the output to look).

Combobox - .net Cascading ComboBoxes Connected To DataSet From Access - Changing Units And Decimal To Fractions?
Oct 2, 2011I have a DataSet with a DataTable that has several numeric columns of Data. The numeric data is composed of distances given in U.S. Standard units. I currently have my ComboBoxes set up and working, but I need to expand on what I currently have in two ways.I need to be able to convert the Decimal numbers in my data column being displayed to Fractions, is there a way to do this and maintain databinding? In this case its the Display Member of the data source...I need to be able to display my drop down options in different sets of units... I've written Unit Conversion classes to help take care of this, but I don't know if I can somehow do this as well and maintain databinding? I'd like to convert the units on the display members as well...

Check If Input To Group Number And Number Of Units Are Correct Input By Making Error Handling Exceptions
Sep 23, 2010Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?
