Hi,

By default tooltips are disabled. Set the flowchart 's ShowToolTips property to true and they should display fine then.

Initially the Font property of all diagram items is null/nothing. That makes them draw their text using the flowchart's font. If you need to use a distinct font for a box, first assign to it a new OLE Font instance and you will be able to set the font's properties.

Here is how to set the OLE font in VB.NET:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  fcx.ActiveBox.ToolTip = "test tooltip"

  fcx.ActiveBox.Text = "test font"
  fcx.ActiveBox.Font = New stdole.StdFontClass()
  fcx.ActiveBox.Font.Size = 33
End Sub

Tooltips should work fine when ShowTooltips = true, can you check whether there isn't another object over the one whose tooltip you set.

So this is not VB.NET WinForms application, now I remember you use ASP.NET and IE.

LoadFromString can fail in several situations:

- the string passed to it is not created by SaveToString  or is mangled in some way
- the internal CRC fails, which might be caused again from a 'broken' string
- the version of the control on the client side is older than the one on the server side

So check whether the string is passed correctly and make sure the version on the client end is the same or newer than the one on the server.

Also make sure the FlowChartX editions used are the same, i.e. if you use the Pro edition on the server, use it on the client too. Here are the CLSIDs of Standard and Pro editions:

for the Standard edition:

<OBJECT id="fcx" height="100%" width="100%" classid="CLSID:E3866A1E-48C9-4381-A9E8-82AC3BDDA921" CODEBASE="yourFcCab.CAB#version=3,2,3,0">

Fro Pro edition:

<OBJECT id="fcx" height="100%" width="100%" classid="CLSID:F025BF4E-4081-4c02-86E6-6602AEE846F6" CODEBASE="yourFcCab.CAB#version=3,2,3,0">

Now if you believe there is a bug in LoadFromString, you can test it easy whether that's true by calling LoadFromString on the server side immediately after the SaveToString. If it fails again, then it's not a versioning issue since the same dll is used for sure.

Regarding tooltips, make sure ShowToolTips is set on the client side. E.g. set fc.ShowToolTips in a client side JavaScript. Anyway keep it set on the server too, I don't know whether its value is transferred by SaveToString/LoadFromString.

Hi,

Ok instead of SaveToString use SaveToFile and email the file to our support address so we can test that here with your settings. Do you have your application visible in the Internet by any chance ?
