Asp.net - Restrictions By File Extension In Server 2008?
Sep 6, 2009
I am having problems downloading files possibly due to the file extensions not matching the actual file. What is happening is the File.Exists check is returning false for these even though the named file does exist. Is anybody aware of anything in IIS or even IE which would cause this? I have seen this with .txt, .exe. and .avi files. The .avi works of as long as the file really is an avi and not renamed from something else.

I am using Vb.NET2008 to develop Window Application. When the user enter the File Name on the textbox, I need to check the file name to ensure that it has the File Extension. (Eg. Sales.XLS) I have not done the coding before and stuggling with it.

I found out how to create file extensions on my PC and I want to open my program with the file extension, but how would I be able to load the text in the file extension into a textbox on my form if that's what the extension is for? And another question, how could I make a file extension that would act like a folder? Like store images and sound files and things like that.

I don't really know how to use compression in VB.net, so I was wondering if someone could explain it to me. I'm also wondering if it is possible to create a compressed file with your own extension.

How would i go about checking a file extention to see if it is either
'.exe' or '.ex_'
What i need to be able to do is that if the extention of the file is '.ex_' then that file is copied to another folder, or if the file extention is '.exe' then it is passed onto another routine that will compress is.
Baring in mind that there could be a number of files in that folder.
I already have a routine that will compress the files, just need the above.

I am looking for an advise on how to find out the extension of the file only knowing the name and the location of it. I tried getextension method and some other but they don't seem to do anything to me.
E.G.:
Dim FileFullPath As String = "\SERVERPublicCRM_LibraryOrderMGMLetters" & datagridLetters.CurrentRow.Cells.Item(0).Value.ToString() & ".pdf"

If i have an extension ... say...
vb
<System.Runtime.CompilerServices.Extension()> _
Public Sub Invert(ByVal b As Bitmap)
is there any way of hiding this from inteli-sense if it is not used as an extension?so that pressing ctl+space only triggers it if you go "bitmap.Inve.." rather than prompting on "Inve..."?

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.

I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.
I coded it with:
OpenFileDialogue.Filter = "GDS File(*.gds)|*.gds|All files|*.*"
but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.
I use this code :
Dim name As String = Path.GetFileName(filePath).Replace(".Bak", "")
Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)
Or using this code :
Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream
[CODE]...

Recursive File Copy based on file extension. I have a single root folder that contains numerous folders that contain a few files that I want to extract. For this example, lets state that I want to copy all �txt� extensions and put them into a repository folder.
Example:

I've got a datagridview of 4 columns (bounded to a datasource).I've restricted the first column to only numbers The 2nd column can have input all but numbers The last 2 columns can only have letters. Also for the last 2 columns I programmed that the input is converted to capital letters.
See the following
Private Sub validatekeypress0(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
If Asc(e.KeyChar) <> 13 AndAlso Asc(e.KeyChar) <> 8 AndAlso Not IsNumeric(e.KeyChar) Then
e.Handled = True
[code]....
For the first cell I double click on to edit, the restrictions are fine, but as soon as I click a cell in another column it looks like the restrictions from the previous column(s) are also taken with. At the end, if I double clicked a cell in each of the columns, every column blocks all input.

Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?

Under RichTextBox_TextChanged event, I have
if RichTextBox.Lines.Count() > 2
{
//Message Box to display the user that you are typing more than 2 lines
}
so what i happens is when i have these data in
[0] - "East coast road"
[1]- "New York"
rich text box, when i click Enter, seems it goes into this state
[0] - "East coast road"
[1]- "New York"
[2] -""
and I get the message pop up box saying can't have more than 2 lines, however the last line is just an empty line? How do i handle the line restrictions in rich text box or how do i ensure that when the user clicks enter I don't move to the next line and move to the next line only if there is 1 line in the rich text box?This returns count as 3 where in there should be only 2, how do i eliminate that white space next line?

Is there a way to make specific queries from a specific table to another, and then export it to VB??. I have an access database, in which I have 4 tables and 1 query. There is one table called "Customers","Gears" and "Articles"; the last one is the relationships with the ID between the tables from Articles, Gears and Customers, becuase a customer may have more than two Gears, therefore the Articles as well.
So in VB I made an interface in which it conects to the database to show in a combobox all the customers, after that if I choose a customer, then it is supposed to show de gear in a listbox which the customer has, but the problem is that it shows all the gears from the query and not the specific one from that customer, also it repeats in the listbox the same gear twice or more. I think it is problem from my query, but I really don't know how to use very well Access, so I am depending on VB. This is the code that I got so far (Note in my
