you mean to register along with .dll file ?
I tried generating a .tlb file using regasm but it also did not help.
FYI-- I'm unable to execute regsvr32.exe

What are you trying to do ? Can you explain your problem in detail ?

Actually I've created a component in .net.
I need to make use of it in vb6. So, for this i've made Com visible and register com interop to true in my component.
I've build my component which has generated a .dll and a .tlb file .
Now the .tlb file is visible in my machine and it works in my application fine and i could see the output of it in vb6.
But when i try to install the .tlb file on other machines, it is installing the tlb file.
But in vb6 application, I'm getting error saying "Automation Error The system cannot find the file specified
".
Its showing like this.
what might be wrong ? Its working fine on my machine but unable to get the output on other machines

You use REGASM on the .DLL file to register it. You don't register the TLB.
|
|
|
|
|
is it like Regasm myfile.dll /tlb:myfile.dll
or
regasm myfile.dll
|

It's the first, but you're allowed to try both.

Yes all classes have Guid's and also i've set ClassInterface(ClassInterfaceType.None).
yes, i'm on win 7 i've registered to admin account.
I've tried with /codebase option also but it didnot make any difference
I did not install the dependency dll's on admin account.
Do i need to register the .tlb files with regtlibv12.exe ?
I guess inorder to use /codebase option, my dll need to be strongly name, but my dll is not strongly name because my third party dll is not stronly named .

No. AFAIK, regtlib12 isn't required.

Try
Dim newdbcon As String
Dim oldconnection As ConnectionStringSettings = ConfigurationManager.ConnectionStrings("mydbcon")
Dim dbcon As String = oldconnection.ConnectionString
Dim builder As New OleDbConnectionStringBuilder(dbcon)
builder.Add("Data Source", source)
builder.Add("Password", pass)
builder.Add("User ID", id)
newdbcon = builder.ConnectionString
Dim config As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
config.ConnectionStrings.ConnectionStrings("mydbcon").ConnectionString = newdbcon
config.Save(ConfigurationSaveMode.Modified)

Have a VB6 legacy program that has been running for years and never saw this before.
It opens a text file, reads the contents and closes the file, code is:
f1 = FreeFile
Open filename For Binary As #f1 'Open the file
RawData = Input$(fileLen(filename), #f1) 'read it
Close #f1 'Close it
When a user logs on with a non administrator account and tries to run this they get a "Path/File access error". If they log in using an administrator account it works fine.
Interestingly enough, it does appear to actually read the file, but the warning is bothersome (removing the warning is not an option)
I tried every combination of security on the the file permissions, enabling/disabling Modify, Read and Execute, Read, Write and so-on, the best I can do is generate a "file not found" error, not an access error.
Any ideas what else to look at?
Thanks in advance

If the file is in a 'my documents' directory which is not the logged in user then you will get a permissions error. You could try moving the file to a directory outside of 'my documents'

Thanks, but the file is in a short path off the root of the C: drive

Commonly, non administrator user can't access C: drive. U have to set access right for the limited user from admin.

That looks really cool and brings me back memories of programming back in the Commodore days.

Thanks, did you give it a try?

Yes, I've given it a try, and looks to be something to mess around with on some free time.

Hence, it must be something that's bound to the profile. Are you using any environment-variables? What is the path based on? Can you show an example? Any other relevant code in there that might cause errors, like reading your path from a key in the registry?
No-e wrote: Interestingly enough, it does appear to actually read the file
It "appears"? Please verify the actual behaviour; print out the contents of the file or write it to a temp location right after reading. Does or doesn't it read the file? My guess is that it didn't.

No environment variables, path is read from a configuration file, fairly straight forward. Not sure about additional code, it is very simple procedure, this one reads it and converts it from hex to binary and returns it in an array (of small blocks to be shoved down a serial port in the calling routing).
I could have been more clear on appears, by appears, the file must be read because the system converts it and sends it to a bunch of hardware. The operator tells me they see this happening (the system shows the file being loaded in blocks), and the hardware subsequently goes off and does its thing with this new data, which works correctly.

Since you're getting a Path/Access Violation error, you've got one of two causes.
Either the path you built in "filename" is invalid, or the user that's running the code doesn't have appropriate permissions to the folderpath the file is in.

so, I'm making an ini editor for this game that has no advanced options. I found an INI reader/writer here:
http://www.mentalis.org/soft/class.qpx?id=6[^]
When I debug or run the program on my laptop (where I have windows 7 and vb2010 installed) it works fine. I dual boot to winxp works fine there too
I have two other win7 computers and JIT debugger comes up on both saying:'
Error message: An item with the same key has already been added
I see references to the ini class inside the details. Cause it uses dictionaries. But I get no exception on xp or the dev win7 install.
also note: I changed the project down to .NET 2.0 after I made the project. Does this have anything to do with it?
please help
