It's a reserved combination, not meant to be disabled. A standard application cannot intercept the combination out of security-reasons.
I have yet to hear a good reason to disable that particular combination.

This may be done in windows xp. Is it because in windows xp this combination key just to bring up windows task manager? While on vista & 7 are not. It is for my i-cafe software, so i need to disable CTRL+ALT+DEL.

No, you want to prevent users from getting into your system - the difference being that there might be more ways to accomplish that, even though you have a specific technical solution in mind.
You could disable it with a group-policy. Windows SteadyState might be usable too, but you'd have to verify that with someone who actually used it

Of course, every system must have a gap to be penetrated. But is there any way to disable CTRL + ALT + DEL in win 7 like on windows xp? One example of such in Lock Windows Desktop[^]

You can't find any code because you can't disable Ctrl-Alt-Del at all. This key combination doesn't even make it to the user desktop. It is handled by WinLogon which is responsible for showing the Secure Attention Sequence desktop.
You can disable or restrict everything you can do in that desktop using Group Policy. Doing it from your code is not a good idea, especially if you are not writing your app as a Windows service.

How about running in XP-mode?

|

How about remove the keys from the keyboard?

That's not gonna help you, I'm bringin' my own USB-keyboard; you prepared to lock down the entire station?

You may want to perform some Google searches. Look for Windows in combination with either GINA or kiosk mode.

Only when you're debugging? Not when you simply run the VB6-application? I'd guess that could be caused by a time-out, as the Sql-statement is expected to return a result within a certain period. Your connection-object has a property that you can use to change the timeout-values.

I have a assembly that contains a class and a strongly typed dataset. I want to expose one datatable as the return datatype on a function - but not expose the whole dataset.
For example:
Public Function GetImportSortOrder(ByVal vEffDate As String, _
ByVal vPlant As Integer, _
ByVal vImportID As Integer) As BusinessLogic.DataSet_ImportData.DataTable_ScheduleOrdersDataTable
If I have the dataset modified set to public, the table in question can be seen externally. If I instantiate the datatable, I can create a SO datatable such as:
dim o as BusinessLogic.DataSet_ImportData.DataTable_ScheduleOrdersDataTable
But all the other datatables in the dataset are also listed. I don't want to show/expose the other datatables. If I go into the dataset.designer.vb file and change the modifier to friend on all other datatables, the modifer is changed back to public when I recompile. How can I accomplish just exposing the one datatable and not all of them? The tableadapters have a "Modifier" property that does just this, but not the datatables themselves.
I'm probably overlooking something simple. Thanks for any guidance.

Was my question clear enough or can this not be done? Not a critical question, just curious if it could be done.

I have designed a word processor with some special features anyways I can save the file one time but then after that I get a fileaccess error saying it is being used by another process but its not the only process was the savefile. Does anyone know whats wrong? Please help!
|
|
|
|

yes, this is one of those confusing error messages. When it says that, it really means to say: "Failing to ... because the file is being used by this very process or maybe even another process".
The typical cause is either one of these:
1.
your app has the file still open, i.e. you forgot to dispose of the File, FileStream, or whatever relevant object you used earlier to access that file.
2.
another app is busy accessing your file; typical candidates are indexing programs, and AntiVirus programs (both are very interested in fresh files!). If so, all it takes is a few seconds of patience and a retry.

hi, im doing a quiz application.
how to get a value from website textbox in another class file, in order to do calculations?
Your solution/guidance is much appreciated (:

My project requirement is to "develop assessment materials (electronic circuit module) for an elearning system".
The website will automatically run a randomnize number in a textbox during the page load for each resistor. & it works.
For development purposes we've created few textboxes to calculate the answer once we hit the submit button.
But unfortunately it didnt generate the correct value yet it gave 0.
We've created a formula class file, randomNum class file & resistor aspx.
The calculation is to be done in the class file.
Hope my explaination helps (:

i have tried this. but always showing invalid.
what change i am supposed to do for making the system date format to dd-mmm-yyyy
Dim reg As RegistryKey
reg = Registry.Users.OpenSubKey("S-1-5-21-1757981266-861567501-682003330-500\Control Panel\International", True)
If Convert.ToString(reg).Trim = String.Empty Then
MsgBox("Invalid")
Else
reg.SetValue("sShortDate", "dd/MM/yyyy")
reg.SetValue("sLongDate", "dd/MM/yyyy")
End If
|
|
|
|
|
|
I'd try Registry.CurrentUser.OpenSubKey("Control Panel\International", True)
