View 2 RepliesI'm having an issue trying to pull information from a specific website. I've asked about this once before, but had no luck through searches or responses.In a nut shell, the issue I'm having is trying to pull information from several URLs from a site.When I load the first URL and pull the information, it works just fine. But if I want to pull another from that same site, it acts like it is loading, but doesn't pull the information. In order for me to gather that information, I have to restart the program, but that beats the purpose.So, I wanted to see if the issue was related to cookies or something else the webbrowser control creates when loading a site. If this is the case, I'd like to clear out this information, or at least try it, after each time it pulls the information from the site.

Why are my new (moved to) text files deleting after the move?
If TextBox1.Text = "* DISPLAY SCROLL 10 *" Then
Dim D10A As StreamReader = File.OpenText("LINE 3 UNITS.txt")
D10A.Close()

the file "line 3 units.txt" contains 3 choices. what I need to do is write one of these selections to the new file "line 3 units new.txt" then recognize the contents of this file to control a boolean statement.
Dim W As String = (D10B)
If W.ToLower.Contains("load") Then
LIN3LD = True

I end up with 2 known problems.
1) The new text files delete
2) if the file doesn't delete (for whatever reason) the CONTAIN statement doesn't recognize either "load" or "speed"
I am busy with a project converting VS2005/2008 sln files.
I am quite far but have came acroos a problem with my source code.
I have found the files I need to change, I have changed them to the version that I need.
I now need to read the files back into my program and delete the line I have changed as it contains project numbers that are irrelevant. Then I need to save it.
I have got as far where I have searched for lines that begin with 'Project'. I have changed this also so it's now a question of reading the files in, Deleting the line with the 'Project' number and saving them.

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

In the case where xml.@Type = "null", I want PatientMetricTypeID (a nullable Integer) to end up being Nothing.
Block #1: If()
In this case, it ends up as 0. It looks like Nothing is being treated as an Integer and converted to 0. I can sort of see why this might happen but not fully... I would like to understand exactly how this works, and if there is a workaround.
Dim PatientMetricTypeID As Integer? = If(xml.@Type = "null",
Nothing,
CType([Enum].Parse(GetType(PatientMetricTypes), xml.@Type), Integer))

In this case, it ends up as Nothing -- expected behavior.
