IMHO you have to create a new Font object (of course based on the user choosen font) of the proper size.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hello,
I'm using VB.net with NET 2.0. I would be most grateful if you could post answer to all or any of the following questions. How to:
1. Use custom icon for mouse instead of deafult mouse cursor?
2. How to disable all the other mouse buttons than the left button? Some mice have 3 buttons, some have five or more.
3. How to disable the function keys (F1, F2 and so on)?
4. How to disable Windows-key (the kye between to Alt and Ctrl)
5. How to disable "Menu-key" (the one between AltGr and Ctrl)?
6. How to hide Windows taskbar completely?
7. How to disable (from code) all
8. How to disable Ctrl+Alt+Del?
9. How to disable all Windows accessibility settings (for handicapped people) from code?
This should happen in a way that when the user closes my application normal Windows operation will be restored.

You have to create a custom cursor file (*.CUR), drawing the image and creating the hotspot point for the spot when the mouse clicks. Google for "Create custom cursor file" for software that can do this.
Put the file in your apps resources, then you can set the cursor to your custom cursor using something like:
Me.Cursor = New Cursor(Me.GetType(), "MyCursor.Cur")
re infecta wrote: 2. How to disable all the other mouse buttons than the left button? Some mice have 3 buttons, some have five or more.
In only your application or acrossed entire system?
If it's just your app, then you just ignore the button click. If it's system wide, you need to write a global mouse hook. Good for "VB.NET mouse hook" for examples.
re infecta wrote: 3. How to disable the function keys (F1, F2 and so on)?
Again, in your application only, or for the entire system??
Google for "VB.NET Keyboard hook" if it's the entire system.
re infecta wrote: 4. How to disable Windows-key (the kye between to Alt and Ctrl)
Keyboard hook.
re infecta wrote: 5. How to disable "Menu-key" (the one between AltGr and Ctrl)?
Keyboard hook.
re infecta wrote: 6. How to hide Windows taskbar completely?
You can't get rid of the task bar completely. You can only set it's options to NOT be on top of all other widows. Right-click the task bar, Properties, turn off "Always on top".
re infecta wrote: 7. How to disable (from code) all
What?
re infecta wrote: 8. How to disable Ctrl+Alt+Del?
You can't. It's impossible to block this key combination.
re infecta wrote: 9. How to disable all Windows accessibility settings (for handicapped people) from code?
You don't. This is something that's left up to system group policies.
Look... All these questions lead me to believe your trying to run Windows in a Kiosk mode. Get the Windows XP Resource Kit and it'll explain how to set this up. It takes about half the book to explain it all.
re infecta wrote: This should happen in a way that when the user closes my application normal Windows operation will be restored.
You application shouldn't care about modifiying Windows so heavily.

Hello all,
I'm new to VB, and I'm using VB5 Express and it's a great program tool. I also have some video tutorials for it. But unfortunately I'm having a problem using the snippet below:
http://www.a1vbcode.com/snippet-187.asp
When I create a form, and then add a button, then add the event for the button, then pasting in the code, I'm getting the dreaded
Name 'Listbox1', is not declared.
I'm not sure what I'm doing wrong, but I've looked for the answer, and I'm still stumped. Below is what the complete code looks like.
Public Class Form1
'Place the following code in a command button's click event
Private Sub cmdGetFilename_Click()
Dim sFilename As String
Dim sPath As String
'search for files with vbp extension
sPath = "c:\yourpath\*.vbp"
'use Dir$ to get first matching filename
sFilename = Dir$(sPath)
'retrieve remaining files matching the search pattern
'Dir$ returns zero length string when no match
Do While sFilename > ""
ListBox1.AddItem(sFilename)
'call Dir$ without parameters to get next filename
sFilename = Dir$
Loop
End Sub
End Class
----------------------------------------------------------------------------------------
Any help will be greatly appreciated, and thank you for your valued time.

Maybe you've changed the List Box name on the UI designer (ListBox1 is the default name).

It's not VB5 Express. It's VB.NET 2005 Express Edition. If you say VB5, everyone will think you're talking about the 10 year old VB5, which didn't have an Express Edition.

It would appear that you need to add a ListBox control to your form. By default, it's name will be ListBox1.

In the below code snippet, I know it does retrieve value of those specified columns from the Deals table, but look at dataReader("name"), what syntax is this? dataReader is declared as type of interface IDataReader, how can we use it in a way like calling a function? At the first glance, I think it's an overloaded operator - function form "()", but after checking with some documentation, in VB.Net, this operator isn't on the allowed operators list to be overload. So would anyone tell me what syntax is dataReader("name"). Many thanks.
Imports Microsoft.Practices.EnterpriseLibrary.Data
Imports Microsoft.Practices.EnterpriseLibrary.Data.Sql
...
Dim lubc As New LookupBaseCollection(GetType(SectypeCommon))
Dim sqlCommand As String = "SELECT * From Deals"
Dim dbCommandWrapper As DBCommandWrapper = Me.database.GetSqlStringCommandWrapper(sqlCommand)
dbCommandWrapper.CommandTimeout = Me.database.GetConnection().ConnectionTimeout
Dim dataReader As IDataReader = Me.database.ExecuteReader(dbCommandWrapper)
While (dataReader.Read())
Dim sc As New SectypeCommon(dataReader("transtype").ToString())
sc.Name = dataReader("name")
sc.TheKey = dataReader("thekey")
sc.ShortName = dataReader("code")
...
End While

dataReader("name") is the short version of dataReader.Item("name"). You can do this because the property 'Item' is the default property.

And that sets your post apart from the others in this forum ? A meaningful subject can attract people who can help you.

You need to capture the fact that you've finished typing. You can do that one of several ways. The most obvious is to handle the focus lost event of the textbox and move the focus to the button. Actually, if the button is the default for the form, I think enter will press it for you.
The other ways I can think of, are bound to drive your users mad. You shouldn't just magically move the focus to a button. You could handle the tab keypress and make it move the focus ( that happens for most controls, but for hte textbox, I think it usually just enters a tab ( as you'd hope )

hi,
suppose your textbox & button have name txtFocus and cmdExecute then use following code at keyprees event of txtfocus
Private Sub txtFocus_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtFocus.KeyPress<br />
If e.KeyChar = Chr(13) Then<br />
cmdExecute.Focus()<br />
End If<br />
End Sub
hope this helps

It would be far better to use Keys.Enter and check the Keys variable.

I find it simplest to se the tab order of the objects on the form to the correct flow and to disable the tabstop property on objects that do not need focus.
Set the cancel and where appropriate the accept buttons for the form.
Let the form do the rest!
Don't forget to explicitly cole the form rather than relying on the dialogresult - there used to be an annotying flash on the form in 1.0

recently i moved my website from unix hosting to windows hosting that only supports IIS and not apache. in the site i have a folder called /registered_users which can contain basically any sort of file. now since the .htaccess script handler is not there everyone can go access the file. the username and passwords are about 500 and password obviously is encrypted. I have a sql table that has unencrypted user/pwd now how could i create sumthing similar to what was there earlier. there are like hundreds of html pages within that folder which are added/deleted automatically.
I simply want to give access to entire folder if they login successfuly.
please help

Sounds like a question totally unrelated to VB.NET, have you tried the web dev forum ?

Hello,
I have a datagridview and I have put a combobox column using the designer.
I have set the properties for the datapropertyName, datasource, display member, and view member.
I have used the binding source and have filled when the form loads. The contents are all displayed in the combo box. This part is working ok
I have used the below to fill the binding source.
'Fill the incidents<br />
Private Sub FillIncidents()<br />
Try<br />
Me.TA_Incident_dsComponent_Equipment.Fill(Me.DsAddComponetAndEquipment.Incident)<br />
<br />
Catch ex As Exception<br />
MsgBox(ex.Message)<br />
End Try<br />
End Sub
My problem is that combo box will be filled with all the incidents that are in the database table. But I want to have a "None" option if the user doesn't want to select any incident.
The incidentID is an identity seed and is incremented each time a new incident is added. So I just can't add a new false record with a "None" field.
I didn't notice any text property in the designer when I added the combobox column. I thought I could set the initial text property to display "None".
Is there any method to do this?
Many thanks for understanding my question and any suggestions.
Steve

Probably the best option is to add a new record with an id of "0" or any other number (but i like to use 0's) and a description of "None" to your datatable, for this, turn of the autoincrement and insert that reord, then turn autoincrement on again
To just display none when no incident is selected:
In the columns designer, select the comboboxcolumn and click in the DefaultCellStyle, in the new window that will open, set the NullValue property to "None" or anything youwant to display
I hope you choose the first option
