Pass value in PARAM tag to ActiveX control

gregquinn · November 12th, 2003, 09:41 AM

I've been searching for two days on this. I've asked forums, I've searched Google, I've picked up bits and pieces from forum posts, but am still stuck.

I have created an ActiveX control for a web page.

Now I need to pass a parameter to the ActiveX control from the web page. I have added a PARAM tag to the control's OBJECT tag...

i.e

<PARAM Name = "UserID" Value = "177">

Now could somebody please show me how in my ActiveX control code, I can access this value in the PARAM tag.

Thanks
Greg

The idea is that the PARAM statement initialises the value of a corresponding public property in your ActiveX control. So if you already have a UserId property then that is where the value of 177 will be. If you don't have a UserId property then you need to add one.

Yes, I understand that. I have been trying to get that working from other code samples I have browsed through. But still, the value does not get passed.

Here is code from my ActiveX control below... Its supposed to change the ActiveX control's txtUserID to the value found in the UserID PARAM tag on my HTML page, but nothing happens. The value doesn't change. Please check the code and let me know if anything is wrong. I really need to get this working ASAP!!!!

Public Property Let UserID(ByVal New_UserID As String)
    txtUserID.Text = RTrim(New_UserID)
    PropertyChanged "UserID"
End Property

Public Property Get UserID() As String
    UserID = txtUserID.Text
End Property

Private Sub ParamControl_ReadProperties(PropBag As PropertyBag)
    txtUserID.Text = PropBag.ReadProperty("UserID", "")
End Sub

Private Sub ParamControl_WriteProperties(PropBag As PropertyBag)
    Call PropBag.WriteProperty("UserID", txtUserID.Text, "")
End Sub

Hi Greg,

I'm confused about ParamControl_ReadProperties, shouldn't that be UserControl_ReadProperties? Apart from that I can't see anything amiss.

What happens when your control loads? Presumably the User ID field is just blank?

Have you tried updating the value from script just to see if it works? For example, in your HTML page which hosts the control, try adding this script and see what happens:
<body onload='idOfYourObject.UserID="177";'>

I'm having the same problem as described above.

If I use the "onload" approach, it works great but I cannot get it to accept values using the <PARAM> tag.

Does anyone have any ideas about why that might be?

Thanks in advance for your help.

Michael

BUMP Yes I have this problem too, I don't see an answer here... Has anyone figured it out? I can pass properties by using the VBScript shown here, but trying it with the PARAM tag and IE6 doesn't work! Help!

Set the Param value in the Object Tag, something like this

<OBJECT ID="ctlTest"
    CLASSID="CLSID:F70F2603-E21C-4AAE-A86D-33DBF6C3FEC4"
    CODEBASE="TestCAB.CAB#version=0,0,0,46">
<PARAM NAME="Server" VALUE="TestServer">
</OBJECT>

In VB Code:
Private Sub UserControl_ReadProperties(PropBag As PropertyBag)
    gsConnectionString = PropBag.ReadProperty("Server")
End Sub

Now you should have the value in VB code passed from VBScript

I'm having an issue with an ActiveX component. It works on Win2K / WinXP with no issue, on Win98 however, it will not install correctly. The component shows up in C:\windows\downloaded program files\ as the CLSID instead of the name of the component. On Win2K / WinXP it shows up as the component name. Here is my INF file, can anybody help??
