What is the WebBrowser control?

Hi everybody!!

I've done some research on the msdn about the WebBrowser control, but yet I can't find what it is. I can see the properties, events and so on, and by the way it's used i think it might be an ActiveX, but I'm not sure.
So can anybody tell me if it's actually an ActiveX, and if gets registered when Windows is installed? Also, is it used by IntenetExplorer in any of its features?
Please, if someone can help me out by explaining this to me or giving me a link to a page where all of these is explained, I will really appreciate it.

Thanks

Kenia

Hi
WebBrowser Control is not exactly ActiveX but you can develope ActiveX with WebBrowser Control.Here are some links for Web Browser control and there is an article which explains how to create an ActiveX with WebBrowser control.

The WebBrowser control provides a managed wrapper for the WebBrowser ActiveX control.

Dear All,

Unable to convert CString to BSTR! Am I a stupid?! Mad | :mad:

I have an interface method which needs to convert CString to BSTR and return BSTR to caller.
AllocSysString of CString is not copying the data to BSTR.

STDMETHODIMP CTP_Interface_ErrorCode_Wrp::GetAdditionalDataFlag(BSTR *AddDataFlag)<br />
{<br />
	AFX_MANAGE_STATE(AfxGetStaticModuleState())<br />
<br />
	// TODO: Add your implementation code here<br />
<br />
	CString temp = pTP_Interface_ErrorCode->GetAdditionalDataFlag();<br />
	*AddDataFlag = 	temp.AllocSysString();<br />
<br />
	return S_OK;<br />
}

Any one please help me.

Thanks very much, Nani

while compiling My ComClient Iam getting this error .

error C2259: 'CComObject<class CComClient>' : cannot instantiate abstract class due to following members:

warning C4259: 'long __stdcall IDSNInfo::SetEngineInfo3(unsigned short *)' : pure virtual function was not defined.

what might be the error. Iam compiling in Unicode Relese Minsize.

Hello Krishnatv,

Check out the parameter to SetEngineInfo3(), i.e. type unsigned short*.

See whether this parameter corresponds with the parameter type declared in the IDL file.

How to access member functions of coclass from its Interface

mandanani8-Jan-08 16:32

mandanani

8-Jan-08 16:32

I need to pass user defined COM class through COM interface. I passed its interface as I can not pass its coclass. Please correct me if I am wrong.

The code was compiling. Now the problem is I have some data types in the coclass and can not use them from interface.
Could you please let me know how to solve this.

Here below is the code:

//////////////////////////////////////////////////////////////////////<br />
STDMETHODIMP CTP_Interface_Wrp::GetObligorInputData(ITP_CompInputData_Wrp *pVal)<br />
{<br />
	AFX_MANAGE_STATE(AfxGetStaticModuleState())<br />
<br />
	// TODO: Add your implementation code here<br />
	<br />
	pTP_DLL_Interface->GetObligorInputData(pVal->pTP_CompanyInputData);   // Error here<br />
	return S_OK;<br />
}<br />
//////////////////////////////////////////////////////////////////////

Actually pTP_CompanyInputData is member vairable of TP_CompInputData coclass. This can not be accessed from its interface class ITP_CompInputData.

I fixed the problem by type casting interface with its coclass.

((CTP_CompInputData_Wrp*)pVal)->pTP_CompanyInputData
Please let me know if this is the right approach.

Interfaces will understand the data types, those are standard, or defined in .idl.
Search for UDT in COM, you will get lot of articles, telling how to achieve it.

How to using C# Class Library in VC++/COM

6-Jan-08 23:45

I have created a class library in C# .Net 2005. I'm not able to create an instance of C# interface class in VC++/or COM dll. It gives an error
0x80040154 "Class not registered"
I also tried registering using regasm. It gives the message Types registered success
I'm not sure if i'm doing it right. Your help will be appreciated. I have attached the code snippet
C#
AssemplyInfo.cs
[assembly: ComVisible(true)]
[assembly: Guid("A4B0A925-5F27-42f3-B8D0-028248A7C210")]
ProcessClass.cs
amespace analyst1
[Guid(ProcName.InterfaceId)]
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface INewInFace
{
[DispId(1)] void BatchStart();
}

[Guid(ProcName.ClassId)]
[ClassInterface(ClassInterfaceType.None)]
public class ProcName : INewInFace
{
internal const string ClassId = "0129FAAF-456E-4e4b-9A72-9685841EAB66";
internal const string InterfaceId = "A2F72F34-0340-49f5-8FDF-7A23A74CC370";
internal const string EventsId = "46C617A1-C148-4c9a-B064-285892110FC4";

public void BatchStart() { }
}

VC++ code
#import "..\\analyst1.tlb" no_namespace named_guids
the follwoing line gives error message "Class Not registered"
INewInFacePtr cp (__uuidof(INewInFace));

The interface INewInFace is not a class therefore it's not surprising that you get Class Not Registered.
