Hello, all.
I've been working on a timer program that I can install on my sons computer in order to allow him a specific amount of time in the evenings/weekends. I've got the program all coded except for one feature:
1. When the timer completes it countdown, I'd like for it to take control of the operating system and pop up a password box that, until the correct psw is entered, essentially prevents the computer from being used (or something very close to that).
I've searched extensively in many forums but have been unable to find anything that fits what I am looking for.
Does anyone have information they can provide in order to code this in vb.net?
Sincerely,
Harold

I once made something similar, the way i resolved it was to make a form with no border, it was completely black and took up the whole screen, when i showed this form i said:
form1.showdialog
Then I had my password form popup in front of that also using showdialog. Showdialog means you can't do anything with the program until the dialog form has been taken away. This means, if the form blacked out the whole screen, you could not click the start button or anything.
To find screen resolution height and width so it works on any resolution:
My.Computer.Screen.Bounds.Width<br />
My.Computer.Screen.Bounds.Height
Use these values to size your blackout form and set the password box to show centre screen. Make sure both forms have the topmost property set to true.
Now, you will also need to block key combinations like Alt-Tab, Alt-F4, Control-F4, the start buttons and Control-Alt-Delete Right?
Put these if statements in the keydown event for BOTH FORMS (the keypreview property should be true for both forms), these will block all common key combinations except control-alt-delete, these will not block the start buttons either:
If e.Alt Then<br />
If e.KeyCode = Keys.Tab Then<br />
e.Handled = True<br />
End If<br />
If e.KeyCode = Keys.F4 Then<br />
e.Handled = True<br />
End If<br />
End If<br />
If e.Control Then<br />
If e.KeyCode = Keys.F4 Then<br />
e.Handled = True<br />
End If<br />
End If<code><br />
<br />
As for blocking task manager i'm not sure, if your son has a limited account i think it can be blocked, for that account, not sure though. But this should get you started. To block the start buttons, i know there is a way to hide the start menu ro disable it, this may help.<br />

I have code working (in VB.Net 2.0, VS2005) to create a windows form control (Windows Control Library), then host that control on a web page (in IE7).
I found a couple of online tutorials for doing this here:
http://support.microsoft.com/default.aspx?scid=kb;en-us;305624
and here
http://msdn.microsoft.com/library/default.asp?url=/msdnmag/issues/02/01/UserCtrl/TOC.asp">http://support.microsoft.com/default.aspx?scid=kb;en-us;305624
However, both of these articles stop short of telling how to get the Javascript on the web-page to respond to events from the Windows Form control! The second one shows how to do it in C#/C++, but not in VB.Net.
Anyone know if it's possible? And if so, How?
TIA,
Owen

How do you send characters to another application's Text Box when that text box is controlled by code that formats the data. I have a legacy application (without source code of course) that I would like to control. I can write just fine into Text Boxes that just accept characters -- but this instance is a Text Box where the legacy code is looking in the Keyboard Buffer for characters and then formatting what is displayed. In other words, its stuffing in the dollar sign ("$") automatically.
This works fine for ordinary Text boxes but not for the ones that format the text box contents:
SendMessageText(WINDOWHANDLE, WM_SETTEXT, Len(TEXTMESSAGE), TEXTMESSAGE)
It seems as if I need to write to the Keyboard buffer so the Legacy Application can process it --- but when I tried that I learned that you have to switch the focus to the Legacy Application because only focused applications can access the Keyboard buffer.
Anybody have a code fragment that can do this?
Thanks

I am working on an ftp application that will download files from my companies various servers. Once the file has been downloaded a menu will appear and give users the option to click on a link label and open a specified folder that contains the downloaded file. The problem I am having is finding a way to open a folder in windows explorer. Does anyone know how to do this? I have found some examples that use the "shell" command but i can never get it to work.
Thanks

I've been converting / writing a handful of apps using Visual Studio 2005 and publishing the files for ClickOnce upgrades.
When we wrote applications with VS2003 we setup app-config files and could change parameters in our apps by adjusting the app-config without recompiling.
Now with ClickOnce we publish to a location on our intranet and install the app on each local workstation. Where is the app-config. It seems like we now have to change the app-config in Visual Studio and re-publish. There should be a way to just go to the app-config at some central location to change parameters if needed?
I'm missing some piece of knowledge that hopefully somebody has.
Thanks for any help

I would like to consume a wevbserice with VB.NET, but I would like to set the URL dynamically because the host for the service might change. I can set the URL be editing the webrefrence but I can not seem to change it programmatically.
I have created a reference to MyService
private service = new MyService.Service
I have tried
service.Url = userInputUrl
but when I try to compile I get a lot of errors like
This is not a member of MyService.
Any ideas.

Hi,
I am trying to run a VB6 application in Windows PE. VB application uses SSTAB control for user interface. WinPE gives an error message stating:
"Failed to load control SSTAB from TABCTL32.OCX. Your version of TABCTL32 maybe outdated. Make sure you are using the version provided with your application."
I have tried to load newer version of TABCTL32.OCX by first unregistering them from Windows System32 folder and then re-register by executing regsvr32 command on both machines where I developed VB6 application (which uses Windows XP Professional) and on WinPE machine. But still to no avail. Problem presists.
Any input will be appreciated. Thanks.

Hi, I have a real problem 
I have been trying for days to thik of a solution for the following;
I have a table called AccessGroup and another called AccessPermission. I have a link table between the 2 because you have any number of AcessGroups assigned to any number of AccessPermissions.
When I want to ADD an access group, I simply input and Name for the AccessGroup like ADMIN. Then I select from a DataGrid, using checkboxes, AccessPermissions. I can choose as many as I want. When I click on SAVE, the link table will be populated with the relationship between the ADMIN AccessGroup and the AccessPermissions Chosen.
Here's the problem. When I select an AccessGroup from a DataGrid for updating, The ADD page appears with a textbox loaded with "ADMIN" and it is ReadOnly. That's fine. What I also want is for the checkboxes in the DataGrid which has all the AccessPermissions in a list to be CHECKED depending on what AccessPermission are assigned for that AccessGroup.
I hope that made sense. Please help.
Thanks!

Can you create an event so that when an item from AccessGroup is selected and then the 'Update' button is pressed, that the table that opens up has the selections of all the possible accesspermissions. Then all you need to do is run through a loop for each permission setup for the item on accessgroup and have it check the neccessary boxes.
