yes at this line
Dim manifestLocation As String = clsidKey.GetValue("CodeBase").ToString it get this error
object reference to set to an instance of object

Almost certainly the error is referring to clsidkey, because it is null.
I could tell you why it is null, but you will learn far more by debugging this section of code. Step through it and observe where one of your variables becomes null, when you don't expect it to be.

i debug the code many and many times
<br />
ins = Registry.ClassesRoot.OpenSubKey("RuleProcessor.Processor")<br />
Dim clsid As String = ins.GetValue("").ToString<br />
the result of these lines is clsis = RuleProcessor.Processor
so i think that the ins will be equal to clsidkey
<br />
<br />
Dim clsidKey As RegistryKey = Registry.ClassesRoot.OpenSubKey(clsid)<br />
clsidkey not null
so it you know any other solution tell me please
Thanks for your help

OK.
And when you move the mouse pointer over the various terms in the error line:
Dim manifestLocation As String = clsidKey.GetValue("CodeBase").ToString
which one shows up as nothing?

clsidKey.GetValue("CodeBase").ToString
i think the property codebase is null
|
|
|

Check the registry manually for the existence of CodeBase.

Hi guys,
I want to read a comma delimited text file from the second line only.I can currently read all the lines, but i want to omit the first line and skip to the next. This is the code that reads all the lines.Can anyone assist.
Dim myReader As New IO.StreamReader(browselocation2.FileName)
Dim filestream As StreamReader
filestream = myReader
Dim readcontents As String
While myReader.Peek() <> -1
readcontents = filestream.ReadLine
Dim textdelimiter As String = ","
Dim splitout = Split(readcontents, textdelimiter)
Dim sql As String = ""
Debug.Print(splitout(0))
End while
Thanks in advance
|

If you are sure the file has at least one line just do readcontents = filestream.ReadLine before the While.
If you are not sure wrap it in an If myReader.Peek() <> -1 Then.
Regards

HI
try this...
dim lp
lp = 1
While myReader.Peek() <> -1
readcontents = filestream.ReadLine
if lp > 1
Dim textdelimiter As String = ","
Dim splitout = Split(readcontents, textdelimiter)
Dim sql As String = ""
Debug.Print(splitout(0))
end if
lp +=1
End while

Read the whole file and just ignore the first line.
|
|
|
|
|
Seems logical to me.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Investigate the OnDrawItem and OnDrawSubItem methods.

I can't find any VB6 examples for what you want to do.

Just in case you haven't yet found a solution, try Googling for subclassing listview vb6.
I did that and there were several hits that sound as though they might do what you are looking for. I would have given a link to the most promising, but you probably wouldn't trust it.

You can do it using either the Process class or by using the System.Management namespace and the WMI Win32_Process class.
Also, you're going to need an admin level account on each machine that you want to get the processes from.
