To better help you, provide a sample of the code you are using.

Hi Paul.. The code which i use to decompress the file is given below..
dim source_file as string = "c:/Compressed.txt"
dim destination_file as string = "c:/Decompressed.txt"
Dim sourceFile As FileStream = File.OpenRead(source_file)
Dim destinationFile As FileStream = File.Create(destination_file)
destinationFile.Close()
Dim ms As New MemoryStream()
Dim zipStream As New DeflateStream(ms, CompressionMode.Decompress)
Dim decompressedBuffer(3500) As Byte
System.IO.File.WriteAllBytes(destination_file, decompressedBuffer)
'end writing
'Because the uncompressed size of the file is unknown,
'we are imports an arbitrary buffer size.
Dim buffer(4096) As Byte
Dim n As Integer
Using input As New GZipStream(source_file, _
CompressionMode.Decompress, False)
Console.WriteLine("Decompressing {0} to {1}.", source_file.Name, _
destination_file.Name)
n = input.Read(decompressedBuffer, 0, decompressedBuffer.Length)
destination_file.Write(decompressedBuffer, 0, n)
End Using
'Close the files.
source_file.Close()
destination_file.Close()

source_file should be sourceFile. You cannot have a string where it is requiring a stream. Same thing applies to destination_file and destinationFile. These are not the cause for your exception, but are a cause for your code not to compile.
You might want to have the following:
source_file.Close()
destination_file.Close()
prior to your attempt at decompressing the file and outputting. This will ensure the buffer is getting flushed and the test compressed file has all of its data written.

Sorry Paul.. I gave the old code .. Below u can find the latest code i used.
In the below.. am getting the exception in line
"n = input.Read(decompressedBuffer, 0, decompressedBuffer.Length)"
'Compressed File path
dim comp_file as string = "c:/compressed.txt"
'File to which decompressed contents has to be written
dim dest_file as string ="c:/decompressed.txt"
Dim sourceFile As FileStream = File.OpenRead(comp_file)
Dim destinationFile As FileStream = File.Create(dest_file)
destinationFile.Close()
Dim ms As New MemoryStream()
Dim zipStream As New DeflateStream(ms, CompressionMode.Decompress)
Dim decompressedBuffer(3500) As Byte
System.IO.File.WriteAllBytes(dest_file, decompressedBuffer)
'end writing
'Because the uncompressed size of the file is unknown,
'we are imports an arbitrary buffer size.
Dim buffer(4096) As Byte
Dim n As Integer
Using input As New GZipStream(sourceFile, _
CompressionMode.Decompress, False)
Console.WriteLine("Decompressing {0} to {1}.", sourceFile.Name,_
destinationFile.Name)
n = input.Read(decompressedBuffer, 0, decompressedBuffer.Length)
destinationFile.Write(decompressedBuffer, 0, n)
End Using
'Close the files.
sourceFile.Close()
destinationFile.Close()

RegSvr32 is used to register COM components, but it your case, it may not work. If this is an .EXE COM server, then the ojects it exposes may not be available at all until your start that .EXE. You won't be able to set a reference to that servers exposed classes, so you might end up using late-binding to get at them. This is not a preferrable situation for someone who is only starting out in C# or VB.NET.
BTW, you asked a question about C# in a VB.NET forum...

You'd be better off asking in the C# forum.

It would be nice if there was a ban function to punish people who do so. Whether the ban is temp or perm is a toss up, but the penalty factor would be nice.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Yep. His question should generally be in either the C# forum, or .NET Framework forum. Pick JUST one, not loads of them. It cannot really be that hard.

Hi,
If he asks again in any other forum it becomes like duplicate one, either it is C# or VB.Net converting a COM component process is same, instead of asking him to post in another forum, we can just understand his problem and answer him with good answer.
Isnt it a good Idea?
Thanks,
Aleem Mohammad.

... says the one who is asking the same question over and over again.
Btw, people are asking him to post in one forum and not asking the same question in four forums.

Hi,
Yep I did it friend but once upon a time, now I am not doing it because I came to know how to behave in this forum. I got much experience in using this forum.
Any way thanks for bringing my mistakes in to my view.
Thanks a Lot,
Aleem Mohammad.

No, it's not. If you post a question in multiple forums, you can get different answers, which isn't really a good thing. You're taking away a continuity of discussion, where the good answers are weeded out from bad ones, and more detail required of the OP is lost in one discussion, but exists in another, leading to misinformation on one discussion thread.

Hi to all,
In Gridview i added the text as No Data Found in EmptyDataText Property of a gridview.
it is working fine when there is no data it should display that message but initially
when page is displayed
that time No data found is displayed which should not happen.
When we select Territory Name & Click on View Button that time that gridview is display
and shows all territories if not available then No Data Found .
Please suggest me how to solve this gridview problem

Why not set the emptydatatext property at runtime then you control the information it displays.

If you set this property at design-time, then run your app, of course this is going to be displayed before you bind the grid to a dataset. Set the property only after you do a fetch and return no, or incomplete, results.

Hello friends,
In my MS access application,i want to move Subfolers from a folder across network using VBA.
I used the below code to move subfolders and files from one folder to another.
Dim fso, fld, subf
Set fso = CreateObject("Scripting.FileSystemObject")
Set fld = fso.GetFolder("C:\Hold\")
For Each subf In fld.SubFolders
subf.Move "c:\Data\"
subf.Delete True
Next
Set fld = Nothing
Set fso = Nothing
But these won't work , if the folder is across network. Getting "permission denied" error..
How can i move subfolders and files across network

Did you read the documentation on the FileSystemObject?? If not, I highly suggest doing so.
You got the permission denied error either because you don't have write/create permissions in the target directory, or the target directory files/folders are ReadOnly and you're trying to overwrite them.

Hi everyone
How can I use a datagridview in vb.net with middle-tier business logic to pass data for Insert, Update and Delete operations. My BLL and DAL are completed, but I don't know how to pass the data from datagridview back to the BLL. I have set the datagridview by passing a dataset to read data through BLL/DAL but do not know how to use for CUD operations.
Your help please
|

When the CRUD operations are completed on the DGV you need to pass the datasource (table) back to your BLL. Your BLL then needs to inspect the rowstate for each row and deal with it appropriately.
I never allow CRUD in any grid control, I always force the user to double click a row and open a dialog to do the CRUD. This allows much finer control and reduces a lot of the angst of using grids. You can then reload the grid table from the database or duplicate the changes in the grids underlying datatable (I almost always reload).
Never underestimate the power of human stupidity
