Separating/Deleting/Copying Lines In String?
Apr 2, 2009
Im working on this webbrowser and i have fully integrated a working Proxy (it will use a proxy such as 100.00.00:0000)It will only change the proxy ip if you do the code:RefreshIESettings("100.00.00:0000")(That is a code i made, declared i mean)Anyway so heres what i wanna do:I want to have a richtextbox or something, with lines of proxy ips, such as this:
100.00.01:0000
100.00.02:0002
100.00.03:0003
[code]....
So i thought maybe if you convert that richtextbox text into a string, it might be easier?

I have a tab delimited text file as so :
name loan period loan amount
John 5 years 6000
Sarah 5 years 6000
Jane 1 month 100
I'm looking to copy the lines where "loan period" = "5 years" to where "loan period" = "1 month", in order to show the comparison. The new lines would be appended at the end of the resulting file. The ultimate end result I hope to achieve is this :
name loan period loan amount
John 5 years 6000
Sarah 5 years 6000
Jane 1 month 100
John 1 month 100
Sarah 1 month 100
I've been toying about this with Visual Basic .Net, and so far, this is what I've come up with
Dim strData As String
Dim i As Short
Dim strLine() As String
lngSize = 0
FileOpen(1, txtloanlistinput.Text, OpenMode.Input)

I have the following code to read a csv file and copy each line to another file as long as it does not contain certain strings, it seems to work a little but it leaves some lines in it shouldn't, and it's also taking lines out it shouldn't as if I keep running it again on each output file it eventually takes everything out!
Private Sub Strip_File()
Microsoft.VisualBasic.FileOpen(1, tFile.Text, OpenMode.Input, OpenAccess.Read)
Microsoft.VisualBasic.FileOpen(2, "C:AcmeIPPMaster.csv", OpenMode.Append, OpenAccess.ReadWrite)

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.

I need to be able to search through a text file and find a line of text, then delete that line and the 7 previous lines and also the line following the searched line. Basically the program creates student records to a text file and asks if the user wants to mark the record for deletion then when the user exits the program, I want it to find the records mark for deletion and delete them.The records in the text file look like this:
Name: Some, Students, Name
Age: 20
Phone Number: (555) 555-5555

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file
Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin
Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"
I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

I understand that an array variable contains a reference to an array object - it is a reference type. string variable is also a reference type. So, if I make a copy of either one, a change to the copy should also change the result I get when I look at the original because both refer to the same object. In the following code, I expected to see "Whoooy" as the result for original and copy for both the array and the string. It works with the array but not the string.

This is what I have for code:
Private Sub restoreDatabase(ByVal dbName As String)
Dim newDbName As String
newDbName = dbName.Substring(dbName.LastIndexOf("_") + 1)
My.Forms.portfolioGenerator.Close()
[Code] .....
It seems like it should be pretty simple, I take in a file name as a parameter, create a new name for it, delete it, then try to copy it back from an older version of the same file, and update the connection string. However, it continually tells me that "The file 'filenamehere' already exists." If I set overwrite to true then it goes through just fine, except it doesn't actually copy the file. Obviously I also check the folder, and the file does in fact Not exist...I've also checked all the file paths and what-not, they are all accurate.

I need to get just the date and times from this list, and put them in variables. so that I'll end up with:
1) A string with a value as a date, which would be "10 January, 2011" for example: strDate1 would have the value of "10 January, 2011"
2) A start time, for example: strStartTime1 would have the value of 9:45
3) An end time, for example strEndTime1 would have the value of 18:00

want to know if anyone knows how to seperate sentences in a dialog box? what I mean is this.I have a rather long warning attached to my closing dialog box that really needs to be there. The problem is that it appears all in one long string and I would like it to in a seperate string.Are you sure you want to exit without saving changes? If you close this window, you will close the program and lose all unsaved data!this is all coming out in one long sentence..what I would like it to look like is this:Are you sure you want to exit without saving changes?If you exit this Window the program will close any unsaved data will be lost!

I'm trying to wrap my head around creating dll, and since I've been using a variation of the code below, i was wondering if someone could comment on if it would be possible to separate the code from the form and create a dll with it, I've been using this in my application successfully and since I'm familiar with it, I thought it would be a good project to learn on.
This is the code for the form docViewerForm.vb
HTML
Imports System.Data.SqlClient
Imports System.Threading

Hi.
Im using this little function to search for text within some downloaded HTML source:
Public Function GetStringBetween(ByVal InputText As String, _
ByVal starttext As String, _
ByVal endtext As String)
Dim lnTextStart As Long
Dim lnTextEnd As Long
lnTextStart = InStr(StartPosition, InputText, starttext, vbTextCompare) + Len(starttext)
lnTextEnd = InStr(lnTextStart, InputText, endtext, vbTextCompare)
If lnTextStart >= (StartPosition + Len(starttext)) And lnTextEnd > lnTextStart Then
GetStringBetween = Mid$(InputText, lnTextStart, lnTextEnd - lnTextStart)
Else
GetStringBetween = "ERROR"
End If
End Function
It works great, but i need to be able to search for something that spans over 2 lines. E.g.
Sam works in a shop from the hours
of 09:00 to 15:00
I want to search for the words "hours of" - but because they are on seperate lines, it cannot find it.
I have tried "hours" & Environment.NewLine & "of" - and other variants of envirmonment.newline (knowing they all return the same value, but, hey, you gotta try) but to no avail. Surely there must be some sort of syntax to ge around this?
Any ideas?
