Explore A File Folder Or Zipped File?
May 6, 2011When I right click a file folder, I get an option called Explore on my pop-up menu. It lets me do this for zipped records also. I want to be able to do this programmatically in my Visual Basic program. How do I explore a file folder and expose its contents in a Listbox. How can I do this for a zipped file? If a folder is zipped and contains a list of files in it, can I go into the file and delete the file without having to unzip the folder. Today, I was able to cut files out of a zipped file and paste the individual files somewhere else. Can I do this programmatically?

Mar 24, 2012I would like to decompress/compress text files in zlib format.
Here's what I tried:
- Downloaded zlibwipa.dll from [URL] and tried to add a reference to it but got an error saying it is an invalid assembly.

View 8 RepliesCreate And Write To A New Text File From An Existing Text File?
Sep 2, 2009I have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

Write Listbox Text To Text File And Keep Columns Aligned?
Apr 16, 2011I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?

File I/O And Registry :: Write A Text File In XP Versus Win7
Sep 28, 2011I am using Visual Studio 2008 on Windows XP SP3. User has Windows 7 Pro (32 bit). The IO code below works for me. The read code works for user, but the write code only works for new files. If the user tries to overwrite a current data file, then no data is written to disk. I have done all the usual IO checking (valid file name, etc.) and have excluded it from my same code. In my app, FileSave and FileSaveAs both call WriteDataFile(FullFileName). Any reasons why FIleSave would work on Windows XP, but not on Windows 7 Pro (32 bit)?
Code:
Public Function ReadDataFile(ByVal FullFileName As String) As Integer
' reads a Data file from disk

' Format is a text file, with [TAB] seperators and [CR][LF] as line terminators
