Generally, yes. But what and how it's passed depends entirely on the parameter(s) of the function your calling. There are no hard and fast rules that work for every parameter.

I’m currently using IO.Directory.Delete(folderToDelete) to remove a folder. The problem is that it will not delete a folder that contains other folders and/or files.
Does anybody now how to remove a folder even if it has sub folders and/or files?
Could I use IO.Directory.Move(folderPathToDelete,"") or is that 'bad practice'?
Thank
Brad

Wow! This is the first time you've mentioned that this is what you wanted to do with locking files and folders!
Next time, don't take 4 posts to explain what you really want to do!

Hello
I wanted to know how to register an ActiveX.EXE file (writen in VB6).
as long as regsvr32.exe only registers ActiveX.dll and .OCX files.
I tried running the file, but it didn't help while I had a previously registered activex exe (which the same name) in some other location. when I try to create an object from the activex exe, the object returned from CreateObject is the object from the first activex..
How can I create an object from the second activex exe?
(THE FIRST ACTIVEX.EXE WAS REGISTERED BY VB6 WHILE I COMPILED IT)
Also I'd be glad if you tell me how to unregister the activex exe file?
Thanks in advance.

---------------------------
RegSvr32
---------------------------
Usage: regsvr32 [/u] [/s] [/n] [/i[:cmdline]] dllname
/u - Unregister server
/s - Silent; display no message boxes
/i - Call DllInstall passing it an optional [cmdline]; when used with /u calls dll uninstall
/n - do not call DllRegisterServer; this option must be used with /i
---------------------------
---------------------------

To extend what progload posted. You have to use RegSvr32 to unregister the first control, then you can use it to register the new one.
RegSvr32 /u c:\path\to\first\ActiveX.dll
RegSvr32 c:\path\to\new\ActiveX.dll

Hi
I know the usage of regsvr32.
but you know, I said that my object is an ActiveX EXE not an ActiveX DLL.
and regsvr32 is unable to register activex exe files.
(My last file to register has an extention of .EXE rather than .DLL created using the ActiveX EXE template in vb6 projects.)
Do you know any other ways (rather than regsvr32 -which doesn't help in this case-) that help me mregister the active X exe?
Thanks

if it is a <activexfilename>.exe it is self-registering(does not need the flag to register),you just run it to register it or use the optional flag:
ActivexFileName.exe /regserver <<<--- optional flag
To UnRegister it, you run it with the flag like this:
ActivexFileName.exe /unregserver
Is this what your looking for?

Thank you! 
it was JUST what I was looking for.

I've been trying for days to write a piece of VB.NET code that will read from winamp's memory space the paths of the files from the current winamp playlist.
The GETPLAYLISTFILE command of the winamp API will only return a pointer to the position of the asked path. An article available on http://msmvps.com/ch21st/archive/2004/02/26.aspx provides a VB6 implementation of this, using the ReadProcessMemory Windows API command. Through digging and asking around, I managed to read the memory contents that winamp points to, but I can't seem to be able to decode them!
In the attached code below that contains all you need to recreate my problem. The function always returns the following giberish: "UVßwXjÝw

hi
i use in my program access database.when i make setup from my program and publish it to cd and run it in another computer it dont recognize path of database
please help me
|
|
|
|
|
it might be helpful to post how your telling the program where to find the DB.
|
|
|
|
|
hi
i am using from odbc and in it's conectionstring there is path of database for example: e:\ac.mdb
|
|
|
|
|
And, is the database being added as part of the Setup? Is the database being installed to the correct directory? Is your application looking in the correct directory?

Did you hardcode the path of the database? If so, and if it is installed in the same directory as you program...use application.StartupPath to make sure the path is correct.
|
|
|
|
|
please many help me
i dont know what's your idea
and say me with a example
thanks
|
|
|
|
|
If your database is in the same directory as your program I would do something like this:
Dim pstrFile as String<br />
pstrFile = Application.StartPath & "\(databasename).mdb"
