I'm using VB.NET 2003. I've written a program to read registry keys from remote computers. However, I must be logged in with my domain ID & password for this to work. If I log in locally (same ID & password as my domain credentials) I get "permission to the registry key is denied".
I've searched high & low for documentation and examples of how to authenticate to a remote pc, but so far have come up with nothing.
Also, we have 2 domains. I have the same ID & password on both domains. If i'm logged in on a PC in Domain1, I can only access Domain1 PC's. So I also need to access Domain2 PC's from a Domain1 PC.
Any help is appreciated.

You must use your Domain2 credentials. Using your Domain1 (or local) credentials will not get you access to any machine in Domain2. Your app can be launched using different credentials (Run As) using Explorer, but I'm not aware of any equivelent in the .NET FCL.

Dim strDate1 As String
Dim strDate2 As String
Dim strDifference As String
strDate1 = "20/12/2000"
strDate2 = "15/12/2004"
strDifference = DateDiff("yyyy", strDate1 , strDate2)
msgbox strDifference
'This will be 4 years
Dont know if that is what you were looking for??

I tried removing then adding the reference to my project. I can find the assembly in the Object Browser, but my code can't!

I have built a custom control which contains a bunch of TextBoxes and 5 Comboboxes. I set the tab indices so that the user can tab through the controls in the proper order. I also wrote event handlers for all the controls so that pressing the return key is equivalent to pressing the tab key.
My problem is that pressing the return key while one of the 5 ComboBoxes has focus doesn't work - nothing happens. You must also press the tab key twice to move through this ComboBox. I have tried deleting the problem ComboBox and replacing it with a copy of one that works, and have also checked the code in my event handlers, but to no avail.
does anyone have any idea what might be wrong?
Thanks!

I dont know what is the problem with you. But the following event handler works fine for both the TextBox and ComboBox. Try this.
private void EnterToTab(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if (e.KeyChar == (char) 13)
{
SendKeys.Send("{tab}");
e.Handled = true;
}
}

Hi to all,
i have developed a Remote Desktop application.
The server in a Windows Service.
When i restart the PC, i send ctrl+alt+del from client, and then i must send the authntication data.
I'm not able to capture the login screen.
Can anyone suggest me a function to capture the login screen, or how i can log in my system by-passing the windows login window (not auto-login)
Thanks in advance

Your app on the target machine is either going to have to run as a service, or your going to have to use the auto-login feature.
When you press C-A-D, all of your user processes are halted, for security reasons, so your app won't be able to do stuff like keylog the password. Services, on the other hand, stay running...

hello to all
1. i have an mdi parent form.and there are some child forms. i want to restrict loading a child form to "only once". i don't want to allow loading a second instance of the same form (while the first instance is still exits) when the user choose to load the same form again.
i mean only one instance of any form at any point of time)
how can i restrict this ... shall i check each form in the MdiChildren array of the mdiparent or is there any other easy way ?
2. if more than one child form are loaded, i want to restrict the user moving through these forms. like if any transaction is in the middle state (not updated) in the present form and the user tries to go to the other form, then i want to cancel the present transaction and allow the user to go to the other form.
i have tried form_lostfocus and form_leave but these couldn't hlep me out ...
how i do this ?
any one please help me out.
thanx in adv.

Hi,
How can I start / stop a windows service from my vb application. can I get a sample
Shenthil

VB6 (w/o WMI): You'll have to call into the Windows API's to get in touch with the Service Control Manager to start and stop Services.
VB6 (with WMI): You can use WMI to get a list of Win32_BaseService objects. You can then use simple method calls to start and stop the service(s) you want.
VB.NET: Very easy. See the documentation on the ServiceController class.

Thanks.
can u give me more detail about using with WMI in vb6.0. Now I am working without WMI.

VB6 with WMI: This will stop a service and it's dependants:
' The "." mean the local computer.
strComputer = "."
' We're going to stop the NetDDE service.
' First, get the list of dependent services and stop them one by one.
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colServiceList = objWMIService.ExecQuery("Associators of {Win32_Service.Name='NetDDE'} Where AssocClass=Win32_DependentService Role=Antecedent")
For each objService in colServiceList
objService.StopService()
Next
' We just told the dependent services to stop. Now we'll wait about 20 seconds
' before we tell the NetDDE service to stop.
Wscript.Sleep 20000
' ...and, finally, stop the NetDDE service.
Set colServiceList = objWMIService.ExecQuery("Select * from Win32_Service where Name='NetDDE'")
For each objService in colServiceList
errReturn = objService.StopService()
Next

I have a IR device connected in my desktop pc, im trying to create a program that will transfer files from PC to my PocketPC (vise-versa), i need to write the program in
vb 6.0 and eVB 3.0, need help on this....thanks

If all your doing is transferring files, you could use Windows Networking to do it, just like two desktops on a LAN. Also, why reinvent the wheel? There are a bunch programs already out there that do file transfers already. Is the cost of one of those less than what it's going to cost you to develope the same thing? What do you get paid in the two months it's going to take to develop this, compared to the off-the-shelf solution?
You can start by looking at http://www.pocketpcdn.com/sections/irdaled.html[^].

I'm having problem with my backend, my visual basic 6.0 program dont work, the winsock control doesn't have the IR protocol unlike its eVB counterpart, pls help me on this. 
|
|
|
|
|
Winsock does support IrDA if any only if you have an IRDA adapter installed in the machine and it's drivers are loaded, and you have the IR protocol installed in the Network Settings.
Also, some IR ports only show up as Serial devices, not network...
The Winsock IRDA documentation starts here[^].

I have an app I'm currently writing that allows users to log out but still leave the app running. When the user logs out, I want to close all child forms related to the main MDI form. Is there an easy way to do this, or do I have to code unload calls for each form?

Sure. In the MDI Parent form, loop through the MdiChildren array, which contains all the child forms and call the Close method on each one (untested code!):
Dim frmChild As Form
For Each frmChild In MdiChildren
frmChild.Close()
Next
