Does anyone know of a script or tool to remove comments from two types of files:
1. ASP file with embedded Javascript & HTML
2. XSL file with embedded Javascript & HTML
So basically it's removal of
// Javascript style comments
/* Javascript style comments */
' VBScript (ASP) style comments
A good script/tool would be one that strips all source code of comments. Then another script/tool that reapplies the comments. So that means storing the comments and line numbers in another file possibly.

I can't see this being all that hard to make.
I'd do something like...
If (System.IO.File.Exists(filepath)) Then
Dim sr As New System.IO.StreamReader(filepath)
Dim line, output As String
output = String.Empty
Dim c() As Char
Do
line = sr.ReadLine()
c = line.ToCharArray()
Select Case (c(0))
Case "<"
'This section will be hit the hardest as most tags begin with the less than symbol
'Look at the next position
If (String.Compare(c(1), "!") = 0) Then
'The -1)
Else
Console.WriteLine("File not found.")
End If
Thats an idea anyway, of course you will have to write the output to a file.

Hi all,
in VB6, is there any way to initialize a typed variable without the need to initialize each var that it's composed of? I want to reset the var but without reseting each member that composes it...
Thanks in advance,
Marc Soleda

No, there isn't. If you want to encapsulte that code into the type, cosider changing your type into a class and providing the reset code in a public method.

Hello,
My question is about memory leak in .NET. Let's say that i have form that loads another form that contains a number of controls(eg datagrids). Form2 does nothing. No data are bound to controls. When i run the program i observe the memory usage in the taskbar and i can see that memory increases when form2 is shown and that is acceptable. when i close the form memory remains the same and when i reopen it memory increases. as you can understand if i have a large app with many forms which using data the memory leak is huge and the app crashes after a while.
Is there a way to implement GC when the form is about to close? Is there a way to reduce memory leak?
Thank you

This question seems to be getting asked a lot - it isn't hard to search the forums. There is a search button at the top.
Here is a link from a thread on this very topic from yesterday[^]

Hi everybody
I have a vb program that send instructions via OLE to an EXCEL instance to do some operations with workbooks. My question is: is there a way to attach a VB Module(but not a Class Module, just a simple module) to an open workbook @ runtime?? And if it's possilble, can I call a function contained in that module??
Thanks

Hi Guys,
In VB.Net, how do you make a connection to an access database and use this connnection throughout the application. Also, when making the connection if we fix the path to the database(i.e. drive, folder..), then when the application is deployed on a different machine on a different drive, will this cause an issue.
With Best Regards,
Mayur

hi,
To connect to access database use the namespace as OLEDB instead of SQLCLIENT.
And then goahead as other connection in >net.
Oh Yes dont ever fix the drive or dir for the connection.
Rather make a string in your config file (that is provided with vb.net application) and read the path from the config file.
Config file gives you the liberty to change the settings and configuration at any time.

On executing of this line
br.Read(bytBuffer, 0, bytBuffer.Length)
We are trying to read a binary files of size 88kb , and merge all these into a single file , sometimes the application crashes on br.Read statement.
We later found out that it is a system error &H80131315& .
How can we solve this ??

If you put a Try..Catch block around the read does it give you more information?

My guess is that you are over-running the buffer or have not properly initialized it. As has been suggested already, encapsulate this in a Try..Catch block and extract more information from the thrown exception.

Dim lFileSize As Long
Dim bytBuffer() As Byte = New Byte() {}
Dim sOutputPath As String = sFilePath.Substring(0, sFilePath.Length - 4)

Msgbox(ex.ToString)
Finally
fsOutput = Nothing
bw = Nothing

End Try
This is the code . We have put try , catch . Also properly initialized it.

Where do you declare btyBufferOutput? Why do you output the contents of btyBufferOutput without putting anything in it?

b { font-weight: normal; }

The actual code is :
Dim bw As BinaryWriter
Dim br As BinaryReader
Dim lFileSize As Long
Dim bytBuffer() As Byte = New Byte() {}
Dim btyBufferOutput() As Byte = New Byte() {}
Dim sOutputPath As String = sFilePath.Substring(0, sFilePath.Length - 4)
Dim fsInput As New FileStream(sFilePath, FileMode.Open, FileAccess.Read)
Dim fsOutput As New FileStream(sOutputPath, FileMode.Create, FileAccess.ReadWrite)
Try
br = New BinaryReader(fsInput)
br.BaseStream.Seek(0, SeekOrigin.Begin)
lFileSize = FileSize(sFilePath)
ReDim bytBuffer(lFileSize - 1)
br.Read(bytBuffer, 0, bytBuffer.Length)
Dim MaxOut As Int32 = lFileSize - 64
ReDim btyBufferOutput(MaxOut - 1)
' DecryptBuffer() function is decrypting the value in bytBuffer and
' storing the decyrpted value in bytBuffer output. this is calling a third- ' party dll
DecryptBuffer(sLangaugeKey, bytBuffer, lFileSize, btyBufferOutput, MaxOut)
Dim Status As Int32 = 0, RetVal As Int32 = 0, Progress As Int32 = 0
Do
RetVal = CryptStatus(Status, Progress)
Loop While ((RetVal = 0) And (Status = 2))
bw = New BinaryWriter(fsOutput)
bw.Write(btyBufferOutput)
fsOutput.Flush()
br.Close()
fsInput.Close()
fsOutput.Close()
bw.Close()
Catch ex as Exception
MsgBox(ex.ToString)
Finally
fsOutput = Nothing
bw = Nothing
br = Nothing
fsInput = Nothing
End Try

I don't know if this is the reason for the error, but it's worth trying:
Don't use ReDim. There is no way of resizing an array in .NET anyway, so there is no reason to use it. Just create the arrays when you know how large it needs to be:
bytbuffer = New Byte(lFileSize)
btyBufferOutput = New Byte(MaxOut)
---
b { font-weight: normal; }

Try obtaining the file size and hence the buffer length by this code...
Dim fileDetails As System.IO.FileInfo = New System.IO.FileInfo(sFilePath)
lFileSize = fileDetails.Length
That will give you the filesize in bytes. I think the FileSize() property you were using returned the size in kB (??).
Trace the code in debug mode and see that the filesize is what's expected. Inspect all other variables for correctness before each line is executed and you'll find the problem.

In the code shown ,
lFileSize = FileSize(sFilePath)
'This function is used to get the filesize
Public Function FileSize(ByVal sFileName As String) As Long
Dim fileInfo As System.IO.FileInfo
fileInfo = New FileInfo(sFileName)
Return fileInfo.Length
fileInfo = Nothing
End Function

So... have you traced the code? What was the value for the returned filesize? Is it valid etc...?
Just giving me more code without explanation or not answering my previous questions ain't gonna get you anywhere fast.

The returned filesize is 88kb . We have encrypted binary files, we are reading this encrypted file into a buffer , and passing this buffer to dencryptbuffer() function. this is a 3rd party dll function which dencrypt the data from the buffer and stored in a output buffer.Then we are writing this output buffer to create dencrypted file.
The application works fine 4 times, but on the fifth time, the application crashes on BinaryReader.Read.
