View 4 RepliesI 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()
[Code]......
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 have my main form then a progress bar form that is shown when the program is running. I simply want to keep the progress bar form on top of the other form and make the other form so it can't be changed.
I've tried form2.showdialog, but that stops the code in the main form from running so it's no good.
form2.show(me) just keeps form2 ontop of form1
me.topmost in form2 does the same as the last thing
setting the form1.enabled = false isn't something I want to do since you can't even move the form when it's like that
So really I'm at a complete loss here
also how can I get the progress to start in the center of form1? There is a setting in the form properties but is doesn't seem to work.
I am listing folders and folder sizes in a ListView for a VB.NET WinForm program I'm writing. I would like to total the folder sizes in the last entry of the ListView and 'lock' it show it always shows (even if scrolling through the list. Is there a way to do this? I'd really like to avoid adding another control on the Windows Form to display the total.
EDIT:Space is somewhat of an issue as I'm trying to keep this window small enough to work in a min screen resolution of 800x600 (I know, not the standard, but I want to make this available to even those in the elderly community with problematic eyesight.
Not a query, just mentioning a problem that might affect others, assuming it is not just some wierd bug on my system, that is. Perhaps someone can check this out.Under screen resolution, Windows 7 has a "make text larger option". On my machine at least, this has the effect of increasing the sizes/positions of any controls set in design mode. Not just in executable, it actually changes the values in design mode.
If you are relying on rescaling sizes/position set in design mode according to screen resolution only you may get incorrect positions when this mode is in use.This affects both VB.net and VB6.
after i set the windows form lock to yes and press f5 fordebug mode , i can still drag the form around the screen

A VB routine assembles a string of email addresses. It is sent to the clipboard with
Clipboard.Clear
Clipboard.SetText Atext
Where Atext is the address string The email client is opened with
lRet = ShellExecute(hWnd, "open", "Mailto:", vbNull, vbNull, SW_SHOWNORMAL)
At this point, when the email client is Outlook, the clipboard doesn't show what was added to the Windows clipboard above regardless of whether we use a left click in the BCC box or a CTRL-V.
I posted problems a while ago with some VB.net code that was not displaying text in All Caps. I thought I had it fixed with a simple check. During Debug and Release modes the code fix works but when I publish the code it fails and Caps Lock is not checked.What am I doing wrong
