Hi all,
I'm new in FusionCharts and interested too use it in future application development, so right now i'm exploring FusionCharts features.
While there's A LOT sample to use FusionChart in ASP.Net WebApplication, I can't found any sample code to use it in VB.Net windows application.
I already to try to make a simple form that consist of 1 multiline textbox to writedown the xml string.
and already add FC As AxShockwaveFlashObjects.AxShockwaveFlash to this form
I use this XML String :
and use this code too render the chart :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGen.Click
FC.Movie = Application.StartupPath + "\\Column3d.swf"
FC.SetVariable("dataXML", TextBox1.Text)
FC.Play()
FC.Refresh()
End Sub
It's work fine if I run the form an click the button for the 1st time.
BUT.., when I want to render the chart again, i need too click the button 3 times before the chart generated again..
So., is it a bug in FusionCharts or it's just my fault? 
I would appreciate any help for my case..

| Hi, Thanks for implementing FusionCharts in VB.NET Win App..and congrats..you have worked it out... to help you out a little ... can you please go through the sample C# Windows Application that we have posted here... http://www.fusioncharts.com/forum/FindPost3221.aspx You can easily convert it to VB.NET. TO come to your query...yes there is a way out....rather 2.... 1st.. core level...where you need to rewind...setVariable and Tplay.. say if the object name is FC.... FC.Stop()
FC.Rewind()
FC.SetVariable("dataXML", strXML)
FC.TPlay("_root")** This is applicable to FusionCharts vFree and v3 charts. Thats it... or ... 2nd method : use CallFunction to call our charts;s externalINterface functions like ..setDataXML or setDataURL . e.g. FC.CallFunction("<invoke name=\""setDataXML"\"><arguments><string><chart><set value='10'/></chart></string></arguments></invoke>") ** this is ONLY Applicable to FusionCharts v3 Charts.

I tried ur 1st suggestion, and.... IT'S WORK...!! 
Thanx a lot for your help
But i little bit curious for your second solution, i try this one :
FC.Movie = Application.StartupPath + "\\Column3d.swf"
FC.SetVariable("dataXML", TextBox1.Text)
FC.CallFunction("")
but there's an error when i run it, it come from the 3rd line:
Conversion from string "
I also already download your code and translate it to VB languange :
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
FC.Movie = (Application.StartupPath + "\\Column3d.swf")
FC.SetVariable("registerWithJS", "1")
FC.SetVariable("dataXML", textBox1.Text)
End Sub
Private Sub button3_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim strXML As String = textBox1.Text
Dim args() As String = {strXML}
FC.CallFunction(FlashCall("setDataXML", args))
End Sub
Private Function FlashCall(ByVal fName As String, ByVal args() As String) As String
Return ("
+ (fName + ("\"">" _
+ (args(0) + ""))))
End Function
But when i try to run it, there's an error occured from this code :
FC.CallFunction(FlashCall("setDataXML", args))
the error is :
Error HRESULT E_FAIL has been returned from a call to a COM component.
Would you give me a clue why it's happen in my code but not in yours

| Hi, As i have pointed out that CallFuction is not supported in FusionCharts FREE version charts.. It is applicable to v3 products...for this you will need to set a variable "registerWithJS" to "1" .. you will find this in the code..

Hey there,
I'm using the same code but when I refresh XML data, some text and bars from previous graph is overlapping the new one. Please take a look attached image.
We are using Free version.
Thanks!!

| hi, There is another way of doing this. Keep the XML in String strXML and use the following code: FC.SetVariable("_root.dataURL", ""); FC.SetVariable("_root.isNewData", "1");FC.SetVariable("_root.newData", strXML);FC.TGotoLabel("/", "JavaScriptHandler");
