View 1 RepliesIn my program you log into a MySQL database. I want to create cookie on the users machine and I want it to stay there until they press the "Logout" button.

We're trying to write code to obtained all the logged on users to a remote machine.
We have the following, which only seems to identify users if they are logged in locally. However, if they're logged in through some other means (such as remote desktop), it doesn't seem to pick those users up.
How can we obtain all the users logged into a machine while excluding those users who only have a process running but aren't logged in (eg, a service is installed by them and might be currently running under their name)?
Dim WMIObject As String = "winmgmts://" & strComputerName.Text & "/root/cimv2"
Dim oComputerQuery As Object
'Contains a sorted list of every user logged into the system

When it is installed on a machine, it will run for all users. But for some users, it is unable to get some data from the database. I have found out that if it is run-as either administrator,or in winxp compatibility mode, it works. But if not, then some users have the problem.The database is in the same C: drive location as the exe, and it doesn't change from user to user.The computer is using windows 7 professional 32-bit.

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

View 9 RepliesI have built a DLL for changing the default printer to a new value and then setting it back to the original. This DLL will be called from a VBA addon to an ERP product. I think the version of the VBA is 6.3.
I have built a Visual Basic 2008 Dll using a COM component. This generates a DLL and TLB file. Using Regasm.exe from the .net frameworkv2.0.50727 folder to successfully register these components on Windows XP and Window 7 32 bit.
However, when I try to do this on a Windows 7 64 bit system, it fails. After some fiddling around, I was able to get a successful registration using the Regasm.exe in framework64v2.0.50727. But after the successful registration, the VBA project still cannot use the DLL.
When I try to Reference the .tlb file in the VBA project, it is not visible even though the dialog filter is set to dll, tlb.If I try to use late binding by using the getobject and/or createObject method, it fails.
There are two ways to answer this request.1. How do I register my 32 bit COM dll on a Windows 7 64 bit machine?
2. How do I write a COM DLL component from scratch for a WIndows 7 64 bit machine using Visual Basic 2008 ( or 2010. I will upgrade if necessary)?
I have a 32-bit java dll which i need to call from a asp.net application on a 64-bit machine.

If I write a program and compile on this 64 bit windows, will it run in 32 bit? I did some reading and from what I understand is if it is not using any specific 64 bit drivers I should be good. I'm not doing anything fancy that I know of as far as drivers. I just wanted to see what everyone's past experience has been.

I'm converting an existing VB6 command line app to VB.net as need a bug or 2 fixed. It uses 3 x Crystal Reports 9 libraries. The only errors I have now are related to CR9 (dll) code, but don't have CR9 on the VSE machine, & dont have VSE on the CR9 machine. We also have a CR11 version of this. The fellow who created them has left & we dont have VB6, he used his own.I can't seem to copy the 3 x CR9 dll's to the VSE machine to get rid of the errors, says the dll access is denied, source file may be in use.I can't install VSE on the CR9 machine so have to create/build it on the VSE machine & copy exe to the CR9 machine.

View 1 RepliesAfter reading a couple of tutorials, it seems that basically NET works quite like java. All the IDE's produce an intermediate code that I have to distribute, and which NET compiles at runtime to machine code and then executes it. Leaving aside the question why so when NET works only on Windows platforms, I have some other more practical questions:Is it possible to directly compile to machine code targeted at specific platform like XP 32-bit or Win7 64-bit?
