Sample Code For Unzipping File
Nov 28, 2009
I have a vbscript that does the following but I want to do it in vb .net and was hoping someone could post some sample code to get me started. The script does the following. Monitors 2 folders specified in a config file. When a zip file is put in the one of the folders it us automatically unzipped to a working folder and then the zip file is renamed to unzipped-<zip>.zip. I am hoping someone could post a visual studio project or code that might help me get started.

I need my program to 'take a peek' into a ZIP file and see if it contains a certain file. I need it to do this many times for a large number of files, so I would prefer it without having to unzip the entire zip-file each time, as that would take far too much time (it's a fairly large zip-file of about 250 MB).Also, I don't need the actual file at all. All I need to know is if it exists inside the zip file.
vb.net
If IO.File.Exists("C:FolderIPFile.zipfolder_in_zipfile.jpg") Then
' "file.jpg" exists inside zip-file!

I have converted this parallel extension c# code sample to VB.NET
[URL]
using the Developerfusion tool here but I am getting multiple errors that I cannot resolve with my limited C# experience.
1) After getting errors I converted System.Runtime.CompilerServices.Extension to Global.System.Runtime.CompilerServices.ExtensionAttribute which is the closest I could come up with, and I get errors on the line (26)
Return SendTaskCore(ping, userToken, Function(tcs) ping.SendAsync(address, tcs))saying that ping.SendAsync(address, timeout, tcs) does not produce a value
2) Around line 196 handler = Function(sender, e) EAPCommon.HandleCompletion(tcs, e, Function() e.Reply, Function() ping.PingCompleted -= handler)
I get an error on 'ping.PingCompleted' saying'Public Event PingCompleted(sender As Object, e As System.Net.NetworkInformation.PingCompletedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

I am trying to create an application that will copy files with a "*.1" extension over to another directory and change the file extension to .tif. The problem is that the *.1 files are located within zip files. Is it possible to copy files out of a zip file without having to extract it? The code I have so far is below. I have only gotten to the point to list all *.zip files found in a specific directory in a listbox. I am really looking to list all *.1 files found within all .zip files in a specific directory. Once they are all listed in the listbox, I will then chose a destination directory, copy them to the destination directory and change the files from a .1 extension to a .TIF extension.

I'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...

I know how to genrate a serial number using GUID. How can I use it. Suppose I send a CD with the software to someone. I do not want just anyone to use it. They have to have the KEY or SN. How can I impliment it so that if you do not have the s/n / key then you will not be able to install the software.

When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.

Is there any chance who can give me a sample code for client-server applications using vb.net 2008 express edition/professional edition?
1. What SQL Server should I use? Can we use SQL Server 2000 for Client-Server application as my back end database? and will use the vb.net 2008 express edition as front end?
2. If we use these two components (SQL Server 2000 (Back-end) + (VB.Net 2008 Frontend) do you think this will works properly?
3. If this is possible by accessing via code? then please send me connection string.
4. Is there any database server we can use? asides from sql server? where we can implement client-server applications? how about oracle? MySQL Database Server?

I am looking for a bit of inspiration here, a client has requested me to build a simple remote process monitoring application with capability for smtp notification, when monitored processes go down or come back on-line. Can anyone point me in the direction of some sample code to get me started. I have briefly looked at .net remoting as a potential development path, from my understanding of how this works, the remoting architecture would require both a client and remote server component, (though I am not a 100% sure on this one), however if this is the case, then it will not fit the bill, as one of the fundamental requirements is that no additional software can be deployed on the servers which are to be monitored
