I need to get the users ID using the username information through VBScript

I'm not a VBScript expert but according to the API reference the AddUserAccount method (https://www.m-files.com/api/documentation/#MFilesAPI~VaultUserOperations~AddUserAccount.html) seems to return the created user account, so you should be able to get the ID from the UserAccount object (https://www.m-files.com/api/documentation/#MFilesAPI~UserAccount.html).

Thanks for your help!
I have no experience with VBscript, could you send me an example script?

Hello, I think you need to modify this:

oVault.UserOperations.AddUserAccount oUserAccount to

dim userid : userid = oVault.UserOperations.AddUserAccount oUserAccount 

and then:

oPropVal.TypedValue.SetValue MFDatatypeLookup, userid    or

oPropVal.TypedValue.SetValue MFDatatypeLookup, userid.ID

Thank you for your help! I made the change and it did not work shows an error.

In my origianl script when I put "oPropVal.TypedValue.SetValue MFDatatypeLookup, oUserAccount.ID" it creates the Login and User, but when setting the 1150 property, an error occurs informing value "0".

Thank you for your help! I made the change and it did not work shows an error.

can you paste the whole script again here?

from your response, you partially modified the script.

Ok follow:

Option Explicit

Dim oServerApp: set oServerApp = CreateObject("MFilesAPI.MFilesServerApplication")
oServerApp.Connect 2, "user", "password", "SERVERNAME", "ncacn_ip_tcp", "localhost", "7766", "DEMO VAULT", false
Dim oVault: Set oVault = oServerApp.LogInToVaultAdministrative(VAULTGUID)

Dim oEmail: oEmail = PropertyValues.SearchForProperty(1089).TypedValue.DisplayValue

Dim oLoginAccount: Set oLoginAccount = CreateObject("MFilesAPI.LoginAccount")

oLoginAccount.AccountType = MFLoginAccountTypeMFiles
oLoginAccount.LicenseType = MFLicenseTypeNone
oLoginAccount.EmailAddress = oEmail
oLoginAccount.Enabled = True
oLoginAccount.UserName = "user-" & oEmail

oServerApp.LoginAccountOperations.AddLoginAccount oLoginAccount, "password"

Dim oUserAccount: Set oUserAccount = CreateObject("MFilesAPI.UserAccount")

oUserAccount.Enabled = true
oUserAccount.InternalUser = true
oUserAccount.LoginName = "user-" & oEmail

oVault.UserOperations.AddUserAccount oUserAccount

Dim oPropVal : Set oPropVal = CreateObject("MFilesAPI.PropertyValue")

oPropVal.PropertyDef = 1150
oPropVal.TypedValue.SetValue MFDatatypeLookup, oUserAccount.ID
Vault.ObjectPropertyOperations.SetProperty ObjVer, oPropVal

oServerApp.Disconnect()

Try with this.

Option Explicit

Dim oServerApp: set oServerApp = CreateObject("MFilesAPI.MFilesServerApplication")
oServerApp.Connect 2, "user", "password", "SERVERNAME", "ncacn_ip_tcp", "localhost", "7766", "DEMO VAULT", false
Dim oVault: Set oVault = oServerApp.LogInToVaultAdministrative(VAULTGUID)

Dim oEmail: oEmail = PropertyValues.SearchForProperty(1089).TypedValue.DisplayValue

Dim oLoginAccount: Set oLoginAccount = CreateObject("MFilesAPI.LoginAccount")

oLoginAccount.AccountType = MFLoginAccountTypeMFiles
oLoginAccount.LicenseType = MFLicenseTypeNone
oLoginAccount.EmailAddress = oEmail
oLoginAccount.Enabled = True
oLoginAccount.UserName = "user-" & oEmail


oServerApp.LoginAccountOperations.AddLoginAccount oLoginAccount, "password"

Dim oUserAccount: Set oUserAccount = CreateObject("MFilesAPI.UserAccount")

oUserAccount.Enabled = true
oUserAccount.InternalUser = true
oUserAccount.LoginName = "user-" & oEmail

dim userid : userid = UserOperations.AddUserAccount oUserAccount

Dim oPropVal : Set oPropVal = CreateObject("MFilesAPI.PropertyValue")

oPropVal.PropertyDef = 1150
oPropVal.TypedValue.SetValue MFDatatypeLookup, userid.ID
Vault.ObjectPropertyOperations.SetProperty ObjVer, oPropVal

oServerApp.Disconnect()

With this script an error occurs when trying to save the Script:

Cliente Novo, StateCondition, 28, Expected end of statement (0x80040008)

dim userid : set userid = UserOperations.AddUserAccount oUserAccount on line 26

Sorry I had put 2 blank lines in my script (I removed Now), the error occurs on line 26 even.
Include your last change and the same error occurred:
Cliente Novo, StateCondition, 26, Expected end of statement (0x80040008)

then try:

dim userid : set userid = UserOperations.AddUserAccount(oUserAccount)

I managed to save the script and when running the message occurred:

Cliente Novo, StateCondition, 26, Variable is undefined: 'UserOperations' (0x80040008)

dim userid : set userid = oVault.UserOperations.AddUserAccount(oUserAccount)

New error: 

RPCDocumentOperationsHelperPrivate.cpp, 9535, Value '80' does not exist, or is a conflict object. (0x800408E8)

The script created the user account and it has this ID. Just failed to set the value on the property.
