Hi
VB6 does not support tiff directly
but you can use GDI+ APIs[^]
or a 3rd party control like :
alternatiff[^]

I was told that VB.Net has the capability of displaying a Balloon Tooltip but no one seemed to know how to do it.
There are lots of projects on The Code Projects that use C# to create balloon tooltips but nothing in VB.Net
Does anyone know how to implement Balloon Tooltips in VB.Net or have a project that shows how to create that type of tooltip.
Thanks

No I dont have any examples. But why dont you just use an assembly generated with C# in your VB.Net app?
|
|
|
|
|
I tried to do that with 2 c# projects but I couldn't find enough info on how to use it after I added it to my references.

I downloaded that before going to this message board and I couldn't get it to work. However, that has been about a week ago and I've forgotten what problem I ran into.
I'll look into it again. But if you had to do something to make it work I would appreciate finding out what you did.

I looked at the code again and I remembered that I could not figure out what code I needed to use to make it work. I added a textbox to the Form1 and then tried to use the mouse hover event. The only success I had was the Dim tp As New BalloonTool. Then I could get any thing going from there.
This is the code I am currently using and I am just displaying a normal tooltip. But I would like to display a balloon tooltip.
Private Sub DataGrid1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGrid1.MouseMove
Dim GrdX As Int32
Dim GrdY As Int32
Dim htInfo As DataGrid.HitTestInfo
Try
htInfo = Me.DataGrid1.HitTest(e.X, e.Y)
If htInfo.Column = 1 Then
Dim colCount As Int32
colCount = ds.Tables(0).Columns.Count()
Dim tipText As String = Me.DataGrid1.Item(htInfo.Row, colCount - 2).ToString() & " " & Me.DataGrid1.Item(htInfo.Row, colCount - 1).ToString()
If tipText.Length > 0 AndAlso tipText.Trim() <> "0" Then
Me.ToolTip1.SetToolTip(Me.DataGrid1, tipText)
Else
Me.ToolTip1.SetToolTip(Me.DataGrid1, "")
End If
Else
Me.ToolTip1.SetToolTip(Me.DataGrid1, "")
End If
Catch exc As Exception
End Try
End Sub
If you could help me with this, using the classes you refereneced I would really appreciate it.

I just used the example forms included in the source project, and it worked OK. I did not study the code, sorry.

To make it work you need thes lines of code (as found in the examples):
<br />
'Declarations<br />
Private m_hb As HoverBalloon = New HoverBalloon<br />
<br />
<br />
'in the Constructor<br />
m_hb.Title = "Traders corp. Inc"<br />
m_hb.TitleIcon = TooltipIcon.Info<br />
m_hb.SetToolTip(Button1, "To expediate your process please click here")<br />
After a quick check I noticed that this component wont fit your needs, because it currently doesnt allow to change the tooltip (well it allows it but gives an exception  ).
You will have to extend/correct this component or search for alternatives  . Or you could just make it yourself and write an article

Believe me, if I figure this out there will be an article. It just doesn't seem like it should be this difficult.

Hi everybody.
I found an article in vb.net and one in vb6
but the 2 articles has the same error with the time of detroy.
in vb.net I fixed this error using a timer control.
I will post it soon.

i have create datasets before and now when i apply:
<br />
Imports system.data<br />
it says this namespace cannot be found. why is that?
|
|
|
|
|
first thing's first...
check to ensure you've created a project reference to the system.data module. for certain types of projects they're not created by default.

Hi To ALL!
Can anybody give me some tips for converting an VB6 application to ASP.NET
Thanks

On top of what Colin said, you'll most likely end up rewriting the entire application. Very little in VB6 WebClass or Windows Forms apps translates to ASP.NET.

I make a form in vb.net. I set its window state property to "Maximized". Means my form will open in "FULL SCREEN".
I also set property "Form Border style " to fixed, so that my form cannot be moved or resized.
But after applying properties, my form still be resized and movable. How can i restrict my form, so that it cannot be moved or resized.
Kindly reply me soon

Set the border style to FixedDialog.
|
|
|
|
|
If you set the FormBorderStyle to FixedSingle the form cannot be resized.
There is no property to set the movable state of the Form. Not in VB.Net, only on VB6.
