Multiple Instancing of Internet Explorer

[rama]

I am using Teechart activex 7.0.1.3 version in the IE. I am opening the teechart in the modeless diaglog box. In the first pop dialog box if tooltip displayed and opened the second pop-up dialigbox. while closing the second popup dialog box the IE is hanging. In the Teechart release letter mentioned as below. But still I am able to reproduce the problem.

* Fixes in the v7.05 (until 28/07/2005)
----------------------------------------

# Multiple Instancing of Internet Explorer
Windows could generate an error when closing
if MarkTips tool present. Now resolved.

Hi rama,

As you say, this should be solved. Please, in order to discover what's happening, could you send us a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Hi,

I have uploaded the sample webapplication to the upload page. The file name is "WebApplication1.zip". Extract this zip file and create a virtual folder "TeechartSample".

By clicking "Shoe Modeless" button it will open a dialog box and move the mouse along with the line. It will display the tool tip.

open one more model less and move mouse on the line. It will display tool tip. Now close the model less dialog. THe IE crashses.

Hello rama,

Thanks for the example project and sorry for the delayed reply. We have been investigated the issue and we have found that that change in v7.05 had to be undone as a side effect was a problem on MarkTips when moving mouse out of application.

As a workaround you can create MarkTips tool using Annotation tool. I'll send you an example of this.

Narcís,

Happy to hear on workaround. THank you for your investigation.
Hope I will get the example as early as possible. I hope you can understand my urgency on this issue.

Thanks & Regards,
Rama

Hi Rama,

I sent the example on Friday to your forums contact e-mail address and the e-mail address you used at the upload page. Have you received it?

Narcis,

Thank you for the example. It is working fine. I am trying to implement same logic in my application.

The problem is I am not able to get the date time value for the X to display in the annotation text. While using asmarksTip it displyed the dattime and Y value in the tool tip. I want to achive same thing now. Could you please send a example for this.

Regards,
Rama

Hi Rama,

Yes, you can do something like this:

Code: Select all

    TChart1.Tools.Items(0).asAnnotation.Text = CStr(CDate(TChart1.Series(0).XValues.Value(0))) & _
                                                ", " & CStr(TChart1.Series(0).YValues.Value(0))

Hi,

Now I am able to display the Date time value and Y value in the annotation text.

If the annotation text is going beyond the teechart boarder then it is truncating. But in case of tool tip it displays.

Please give a sample to code to display annotation text if the mouse is near the end of series. The truncation of text might happening because the width of text is crossing the teechart border.

Regards,
Rama

Hi Rama,

Using code below doesn't truncate annotation tool for me. Does it work fine at your end? Could you please modify the project so that we can reproduce the problem here?

Code: Select all

Private Sub Form_Load()
    TChart1.AddSeries scPoint
    TChart1.Series(0).FillSampleValues 25
    TChart1.Series(0).XValues.DateTime = True
    
    TChart1.Tools.Add tcAnnotate
End Sub

Private Sub TChart1_OnMouseMove(ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
    Index = TChart1.Series(0).Clicked(X, Y)
    
    If Index <> -1 Then
        With TChart1.Tools.Items(0).asAnnotation
            .Text = CStr(CDate(TChart1.Series(0).XValues.Value(Index))) & _
                    ", " & CStr(TChart1.Series(0).YValues.Value(Index))
            .Shape.CustomPosition = True
            .Shape.Left = TChart1.Series(0).CalcXPos(Index)
            .Shape.Top = TChart1.Series(0).CalcYPos(Index)
        End With
    End If
End Sub

Thanks in advance.

Narcis,

I have uploaded the sample project to the upload area. The file name is WebApplication1.zip. Extract this zip file and create a virtual folder "TeechartSample".

By clicking "Show Modeless" button it will open a dialog box and move the mouse along with the line it displays the annotation text as tool tip. If you move to 23 point and above the annotation text is truncated. We can not see the full tool tip text. Please let me know the work around.

Hi Narcis,

Please let me know your reply. I am waiting for your reply to take the further decisions.

Hi Rama,

Sorry for the delayed reply. MarkTips tool uses windows hints, Annotation tools don't and therefore they are clipped by the browser window. The only solution is, when calculating the Annotation position, check if its Left coordinate plus its width is greater than chart's width. If so you could make a multiple line annotation tool.
