Error in VB 6.0 : Class not Registered. Looking for object with CLSID :{....}

[DKn]

Hi ,

I am having a .Net Activex control. I have done coding for COMRegistering and Unregistereing in C#.Net. The code is follows..
[ComRegisterFunc tion]
static void ComRegister(Typ e t)
{
string keyName = @"CLSID\" + t.GUID.ToString ("B");
using (RegistryKey key =
Registry.Classe sRoot.OpenSubKe y(keyName, true))
{
key.CreateSubKe y("Control").Cl ose();
using (RegistryKey subkey = key.CreateSubKe y("MiscStatus") )
{
subkey.SetValue ("", "131457");
}
using (RegistryKey subkey = key.CreateSubKe y("TypeLib"))
{
Guid libid = Marshal.GetType LibGuidForAssem bly(t.Assembly) ;
subkey.SetValue ("", libid.ToString( "B"));
}
using (RegistryKey subkey = key.CreateSubKe y("Version"))
{
Version ver = t.Assembly.GetN ame().Version;
string version =
string.Format(" {0}.{1}",
ver.Major,
ver.Minor);
if (version == "0.0") version = "1.0";
subkey.SetValue ("", version);
}
}
}

[ComUnregisterFu nction]
static void ComUnregister(T ype t)
{
// Delete entire CLSID\{clsid} subtree
string keyName = @"CLSID\" + t.GUID.ToString ("B");
Registry.Classe sRoot.DeleteSub KeyTree(keyName );
}

When i Build this .Net project this control is getting registering in the registry and i am able to add this .net control in vb 6.0 form also. its working fine.

I want to test this dll on any other system other than developer machine....
Then i tried to register this dll through Regasm.. The control is registered succefully. but when i tried to add this control in to vb 6.0 form.. I am getting this error: Class not Registered .Looking for Object with ClsId :{...}..

Then i send full .net project to that system and build the .net appliaction. then it is registered fine and working fine in vb 6.0 also.. the problem is comming if i registered that dll through command line.. what is the solution for this...

Plz Help ....

Hi,

If you want to use the .net dll in VB6,
While registering with regasm, you have to generate the "TypeLibrar y" :

[code=vb]
regasm myAssembly.dll /tlb:myAssembly. tlb
[/code]

OR, if you have already registered(With out Type Library),
you can LateBind the Objects in VB6:
[code=vb]
Dim tObj As Object
Set tObj = CreateObject("M yProjName.MyCla ssName")
[/code]

Hi,
When i build my .net Project , both dll and tlb files are getting generated in bin debug folder.

I have tried this code in vb 6.0

Hi,

its an ActiveX Dll or an ActiveX ocx..?
My previous code was for ActiveX Dll

If ActiveX ocx, then remove the code,
add the Control to the project
and from toolbox, directly place the Control on the Form..

Its .Net ActiveX Control.. when i drag and drop to the vb 6.0 form.. the same error...Class not registered.Look ing for object with clsid :{...} is coming..

[DKn]

Hi,
If I register through .Net code... In the registry Editor, the control is registered with the GUID under classRoot . InProcServer32 CodeBase Entry is coming.
When I registered through Regasm this entry (codeBase value) is not there under InProcServer32. This is the only difference I observed....

Is this is the Reason, I am getting the error : Class not registered. Looking for object with clsid :{...}

Please anybody help me...

I suspect the .Net forum would provide a better response to this question.

Hi, i got the solution for this problem...
We need to Use this command..
Regasm /codebase myDotNetControl .dll
Now its working fine in other systems also..
But, the .Net dll must be strong named to use the Codebase command.....

I suspect the .Net forum would provide a better response to this question.
