VS 2008 - Balloon Tooltip Show Invalid Filename Characters
Apr 11, 2009
I am using a Balloon tooltip to show the user which characters are invalid as a filename. I use the IO.Path.GetInvalidFileNameChars array and convert each character to a string, before appending it to a "Invalid filename characters:" string.
vb.net
If IO.Path.GetInvalidFileNameChars.Contains(e.KeyChar) Then
e.Handled = True
Dim str As String = "The following characters are invalid filename characters:" & nl
Dim invalidChars As New List(Of String)
For Each c As Char In IO.Path.GetInvalidFileNameChars
[Code] .....
The result is not pretty: How do I get rid of the 'non-visual' characters (they are probably newlines, backspaces, null chars, etc) so they don't clutter up the list?

I want to display a balloon tooltip in the system tray. Currently, my app has four forms. the main form host the notifyicon. In process of operation with other forms, i want the current form to be hidden , and display a balloon message using the notifyicon of the main form.
in the form about to close this is what i did
c# Code:
frmMain frm2 = new frmMain();
frm2.ShowBallon("Logged in","Check for new mail....");
this.Close();
[Code].....
The problem is that the procedure executes, but dosen't show any balloon .Another problem is that the notify icon does not disapper automatically when the app exits, except you hover the mopuse over it.

I am trying to make a little class to show the balloon tooltip at the moment I got eveything I want working but have no idea how to set the forecolor of text and backcolor.
here the code I am using to show the tip, I added backcolor and forecolor but nothing seems to happen, I am also using Visual Express 2010 if that makes any difference.
vbnet
Public Sub ShowTip(ByVal obj As Control)
Dim tp As New ToolTip()

I have a balloon tool tip and want to show it as follows:
vb
Dim CompleteTooltip As New ToolTip With {.IsBalloon = True, .ToolTipTitle = "Title", .ToolTipIcon = ToolTipIcon.Info}
CompleteTooltip.Show("Click close to confirm changes", btnClose, CInt(btnClose.Width / 2), CInt(btnClose.Height / 2), 5000)
i would have thought if i specify that i want a balloon tooltip the point that i specify would be the point that the balloon points to - NOT the upper left point of the tooltip itself... how can i specify the balloon point rather than the upper left point?

If i have a NotifyIcon is it possible to owner draw the balloon tip for it?If not i was thinking it would have to be done this way:Work out if the icon is visible or not (as in not collapsed in windows vista / 7 / xp), and if not call ShowBalloonTip to force the icon visible then hide the balloon somehow. Work out the rect in relatio

I have a notifyicon in my VB.NET application. At the start of the programm it goes to the system tray and adds some global hotkeys. If one of this keys is pressed, then a balloon tooltip appears. At design time I have set up the balloon icon as 'Info'. But when the balloon tooltip appears, no 'Info' icon comes up, only the standard balloon tooltip. However, when the icon type is set up to 'Error' or 'Warning', it works. Why this behaviour? (on Vista)
An another problem is, that I set the timeout property f.i. to 500 milliseconds, the balloon tooltip is even visible after some seconds too.

We are seeing a problem with tooltip balloon that its stem is not pointing to the control to which it is associated Our requirement is thatfter a button click, the tooltip should pop up for a second or two without mouse hover.Then, when the cursor is hovered on the control, then the balloon should be seenWe are successful with point 2 but for the point 1, the tooltip's stemis pointing to some random location instead of the control of interest.
The code is as follows -
errorTooltip.IsBalloon = True
errorTooltip.UseAnimation = True

Every six minutes, my program talks to an instrument. Then, it activates a notify icon's tool tip for half a second to say what it did and when. According to the databases, everything's been going great, but the balloon tip text is a week behind and still trying to catch up. I'm getting text after text about stuff that happened last week. You should know that no one's touched the machine for at least a week. Because the program talks to the instrument every six minutes, the computer never hibernates, never shuts down, and the screen saver is off.

Well I've recently discovered that trying to create a file with so-called 'illegal characters' will cause your application to crash.. How do I find these characters in a string and replace them with nothing?
The invalid characters are / : * ? " < > | if that helps.

I have a small application in which I need to show alerts if a particular condition is met. I have an mdi form and several child forms. Now the best way to show an alert is to show a tooltip on the right side corner of my mdi form. Though this works, but the problem is I want user to close the tooltip once he has read. Now the tooltip that vb.net provide does not support click events. If I give a long time duration the tooltip would be open all the time and if I give a short duration then it will close quickly. What can I do ?

I have a piece of code to debug. Because of unknown bugs it creates a dummy filename. I want to track all the pieces of code who fires that creates the dummy filename, so I can change the dummy file creation to a thrown exception. Since I the dummy filename is stored on a string, I plan to modify that string to contain an invalid NTFS filename, maybe containing invalid chars. Is there a reason to prefer some invalid chars over others? There are some predefined invalid NTFS filename destined to this purpose? (I may think of AUX , COM1 , LPT1 or PRN , but those names run the risk of start sending data to a port instead of throwing an exception).

Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>"
Dim patternend As String = "</FileName>"
Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)
[code].....

I have a TextBox with a list of filenames in it. The user is able to change these file names, but I don't want them to enter invalid characters, such as slashes or question marks.
I've tried two approaches, but they are not satisfactory:
1. Detect the key pressed with the KeyDown event:
Use e.KeyValue to detect keys like Keys.Oem5 (= backslash), then use 'e.SuppressKeyPress = True' to suppress the key.Problem is, with different Keyboard layouts, The Oem5-key isn't always a backslash.
2. Filter the text:
Use the TextChanged event and do a Replace("", "") on the text for every invalid character (there's 9 of them).Of course this will create 'lag' with every keystroke, especially if there's a lot of text. Also the text-cursor and scrollbar will jump back to the top-left when using Replace.
In short: I'm looking for a way to detect the character that is being entered and suppress or remove it when invalid.

I'm aware that the tooltip object can contain an image. I am unable to make an image popup when the mouse hovers over a datagridview cell, since it is not possible to attach a tooltip object to a cell ( myTip.SetToolTip(gridCell, "Hello") generates a compile error)

I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing)
Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)

I only want the tool tip to show when the user is editing a cell in columindex 1.
The following below does note seem to be working.
Private Sub dataGridView14_CellEnter(ByVal sender As Object, _
ByVal e As DataGridViewCellEventArgs) _

Currently have created/extended the DomainUpDown class hoping I would be able to add one simple feature: I was hoping to be able to show a tooltip when the user mouses over the control that would show the next and previous item in the list. However the DomainUpDown class does not have a mouseenter event and overriding the mouseenter method does not seem functional. Is there something I am missing or do I just need to create my own MouseEnter event?
Private tips As New ToolTip With {.AutomaticDelay = 0, .AutoPopDelay = 0, .InitialDelay = 0, .ShowAlways = True, .ForeColor = Color.WhiteSmoke, .BackColor = Color.Black}
Protected Overrides Sub OnMouseEnter(ByVal e As System.EventArgs)
MyBase.OnMouseEnter(e)
Console.WriteLine("list entered") 'testing purposes, never is printed on mouse enter
tips.SetToolTip(Me, "Up = " & Me.Items(Me.SelectedIndex - 1).ToString & vbLf & "Down = " & Me.Items(Me.SelectedIndex + 1).ToString)
End Sub
