[URL] There's a RemoveEntry() function to remove a file, but I can't seem to find a function to remove a directory... Does DotNetZip support directory removal? If not, what are some other libraries I could try?

I'm currently working on a utility software, file compression, with VB.Net. And using an open source library to compress and decompress files - DotNetZip - and already running.
My friend told to make it unique and not traditional, that I make the output compressed files cannot be opened with other compression software. Now my question is... is it possible that way? Using an open source library which the output format is ".zip"?
I first thought that changing the file extension of the compressed file to unknown format so it can't be opened when you try to decompress it, unfortunately, using the "Open With..." function of windows it could still be decompressed.
Is it really possible? OR what other features can I add that WinZIP doesnt have yet? I compared my work to WinZip since the same output is ".zip".
In ASP.Net two of the possible ways to make the zip files are
Sharp Zip Library
Dot Net Zip Library
How can i use any of these in Classic ASP to make the zip files ? And which one will be better ?

Public Structure ReportOrderType
Public ReportName As String
Public ReportDate As Date
Public SaveFile As String
End Structure
[Code] ....
Basically, I have a list of reports. In one place they get ordered, and later on the program looks to see which ones have come back -- see if the .SaveFile exists on disk. If it exists, then that report gets processed, and then I want to remove that item from the list of reports-on-order. However, I get an error message back that by doing the .Remove(R), I've changed the list itself & things won't go well with the rest of the For Each loop, which makes some sense.
When I get to this routine, the list of ordered reports will be something from a couple of dozen or less, and some number of them (perhaps zero, perhaps all, probably a few) will exist & be processed & then should be removed from the list. How should I go about accomplishing this? This is my first time working with List(of t) as a Visual Basic tool; everything I've used in the past has been with arrays, and I can do this there.
I need to parse an alphanumeric string leaving the characters "0-9", ".", "/" and space & remove everything else. I use "[^0-9./ ]" as my regex string and it works well. But now I have a couple other conditions that I dont know how to handle with my regex string. I actually only want to keep the "." character if it falls between two digit characters (ie. 3.5), otherwise remove it. And also I need to replace any "-" characters with a space if it falls between two digit characters (ie. 2-1), otherwise remove it.
View 1 RepliesI'm making quite the complex program, and while I try to figure out some more advanced methods that work better for what I'm trying to do, I'd like to learn how to do this (which is a bit of a roundabout method to what I've been trying). I'm wondering, how can I programatically create and remove objects? For example, I have webbrowser1. I want to remove it and create another webbrowser that I will also name webbrowser1. (therefore, the instance of the original must be removed)

View 6 RepliesI have a problem with a bit of code that is supposed to delete every controls on a form appart from the 2 first controls
vb2010
Private Sub ClearCheck(ByRef Container As Control)
Dim ctl As Control
Dim Boxtype As Control
Dim i As UShort = 0
[Code]...
The behavior is strange, I can't find any logic to it, it will sometime delete a part of the objects, other times it will delete other part of the objects. If I run it more than once, I can achieve the wanted result and remove all controls except the 2 I want to keep. It's as if it was checking 1 out of 2 controls.
To give you a better idea I have a combobox on the form and depending on choice it adds appropriate controls (not show/visible true) and add a second combobox to refine the search. If I change the value in the first combobox I want to remove the added controls from the previous combobox.SelectedIndexChanged as well as any control created by the following combobox from the form.
If need be I'll post the code that creates those new controls, but it's quite long so I didn't include it in this post

I have a file that is constantly altered, and if an error happends, I want to have a backup.

View 10 RepliesI have strMyString that contains about 5000 lines of data. There are some lines of data that need removing if they contain a certain string, such as "http", "www.", ".com", "cat", "fish", etc. The whole line needs removing. Each line is separated by a vbNewLine or similar.
How can I do that? Does it need pasting into a rich textbox first before processing?
