Thanks. I am using my own securty system to validate users; that works fine. The piece that was missing for me is the management of the Controls. regards.

I take it you've got it figured out now? I mean you were missing the Enabled property??

Dave thanks for your guidance on figuring this out. Basically, I dimmed the frmlogin in my frmmain and use the login credentials to determine whether or not to "Me.btnMaintainEmployees.Enabled = False". This works great. Thanks again.

Hello Everyone,
I am trying to code a program in VB6 where i have a DLL. My aim is to call some functions from the dll. I am totally new to this VB envoirnment and hence require some help. Actually this is a part of PHP project which is to be interfaced with some other application through this dll. The dll guys gave this code and i simply copy pasted this code in VB application. The minute i compile the code i get an error "Constants, fixed length strings, arrays, user-defined types and declare statements not allowed as public members of object modules."
This is the part of the code, i am getting error on the very first line of the code.
Option Explicit
Declare Function RTSOpen Lib "RTSLINK.DLL" Alias "Open" () As Long
Declare Function Send Lib "RTSLINK.DLL" (ByVal strRequestXML As String) As Long
Declare Function GetLastErrorMessage Lib "RTSLINK.DLL" () As String
Public Sub vbSend()
Dim nResult As Integer
Dim strErrorMsg As String * 255
Dim strRequestXML
Dim strResponseText
....
Regards,
Chaitannya

What kind of project did you create?? What file is this code being pasted into??
Mind you, it's been about 7 years since I last used VB6, so my memory may fail me at any point...

|
|
A simple exe project, copy pasted the code in the Form page.
|
|
|
|
|
Hmmm... It would appear that somewhere along the line there is code outside of a function/sub that can only work inside a function/sub. This is anything that isn't a declaration.
It's also possible that some of the code you were given will only work if pasted into a Module, not a form.

Hi All,

VB6 samples are getting harder and harder to come by. You can find some equivilent VBScript samples that show you how to use WMI for various things in MS's TechNet Script Repository[^].
You won't find the exact code you're looking for, but it shows you how to use WMI in VBScript code. VB6 code would be pretty close to it.

Check the documentation on the RegistryKey.SetValue method. All you have to do to change the default value is specify the value name as either Nothing or an empty string ("").
myKey.SetValue("", "Some value")

Is there any limit to the maximum number of tab that can be added to TabStrip Controlin VB.
In my application after 254 tab it give memory error.
I am not able to find nay documentation specifying the maximum count.
If there is any maximum count and if can be increase in any way ?

I guess the real question is, why do you hate your users so much that you'd create such an awful UI. 254 tabs ?
255 is obviously #FF, it's the max value of a byte. So, it's a logical maximum value to have. And no, you can't change it without writing your own tab control.

Yes I appreciate what you suggest. But some application can need it sometime 
In case of Excel, we should not able to add more than 255 sheet! No we can.
I got the solution for the above question.
Instead of using "Microsoft Common Dialog Control 6.0"
I will use "Microsoft Forms 2.0 object Library" TabControl

 Tabs inside Tab, then suddenly you can put 255 x 255 tag pages! I would hate to be the user, or in general vicinity of that application....
Or you can redesign the application by dynamically load the form/area that the user want to look at.

I did not get u ?...
Any way I just told that Windows Common Control's tab control can not handle more than 255 but the other one can handle in thousands..
And of course the tabs added are dynamically. No body is going to give user interface with 255 tabs. But we can think of extreme conditions. If you are using VC interface I think it can open more than 255 files at a time in different tabs. But in practically no one would ever open...
U are using lots of application that support more than 255 tabs 
If you are reading this article in Firefox now it might able to open 255 tabs,

I am creating a database using MS Access. I want to have the Member ID field to able to generate 5 digit Random Numbers that will not duplicate (unique)on Get Focus. I have very little experience in VB coding.
Please help to write VB.net code for accomplishing this need.
Thank you all.

that is a contradiction, it is either random or unique, can't be both: after 99999 numbers I
will be able to predict your last number, how random is that?
The one way to get uniqueness with maximum random appearance, is by creating the entire
collection of numbers, then picking one at random and removing it from the collection,
until all are gone.

Then how did you inherit this task ?
The easiest way to do this ( although nasty ) is to make the column unique in your database, then keep generating numbers until one is not found in the DB. This is, of course, a disaster. The other way is to build a list of all possible numbers, then remove all numbers already in use, and pull numbers out of that list at random ( which is pretty much what Luc said ).
One other way is to create a GUID column in your database, but that's more than 5 characters. It does have the advantage of happening all in the DB. I've done licensing where we use 12 character keys and I generate them in the data layer in a proc that generates GUIDs, checks if a substring is already in the DB, and if not, spits them out.
