How to use #import for different Windows OS version

3-Sep-09 21:23

Hi
I want to hide my custom toolbar on IE(all versions). I can hide standard IE toolbar by using
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Toolbars\Restrictions

NoToolBar" Value = 1

which hides all standard button from IE. But i want to hide my Toolbar whenever browser starts and show it at particular site. So is there any way to hide by regedit by knowing the guid of toolbar.

Thanks

The location you use for #import depends on the OS you're building the project on - do you anticipate building the project on both Windows 2000 AND XP?

Alternatively, use the #import "libid:library UUID" syntax.

Getting crash while copying a VARIANT type to _variant_t type,

1-Sep-09 4:46

Same thing - open cdosys.dll in the OLE-COM Viewer (you'll find it either in your Visual Studio directory or in your Microsoft SDKs directory, both of which are in c:\Program Files) and look for the library's GUID.

How are you doing the copying?
If you're creating a new object you just use the constructor to do it.

VARIANT v;
_variant_t vt(v);

com interop exception with IIS webserver using in asp.net web application

30-Aug-09 13:34

(Disclaimer: I've not done this myself, it's from some knowledge of the docs).

use IShellFolder::ParseDisplayName[^] to get a shell item ID list for the folder your string refers to.
use IShellFolder::BindToObject[^] to get an IShellFolder relating to the shell item ID list for your folder.
use IShellFolder::CreateViewObject[^] to get the IShellView interface.

we are using any VB 6.0 com component through interop in asp.net web application. surprisingly it works fine
with the visual studio web server but does not work with IIS webserver. we also impersonate the machine user with highest privilages and other access permission but it still does not work and throw the COM interop exception.

Any help in this would be highly appreciated.

How to do the CoCreateInstance

How to do the CoCreateInstance,when You have only the DLL path and name
say for example I have a Dll named xyz.dll
I just #import it and register it now how I will get its Class ID to do the CoCreateInstance.
Pleae HELP

Stuart Dootson26-Aug-09 22:13

There will be a structure in the code generated by the #import statement that represents the class. You can do __uuidof(that struct) to get its CLSID. Look at the example I have here using Excel:

#import "libid:00020813-0000-0000-C000-000000000046" version("1.6") auto_search no_dual_interfaces rename("DialogBox", "excelDialogBox") rename("RGB", "excelRGB") rename("DocumentProperties", "excelDocumentProperties") rename("SearchPath", "excelSearchPath") rename("CopyFile", "excelCopyFile") rename("ReplaceText", "excelReplaceText")

int _tmain(int argc, _TCHAR* argv[])
{
   CoInitializeEx(0, COINIT_MULTITHREADED);
   {
      Excel::_ApplicationPtr xl;
      if (SUCCEEDED(xl.CreateInstance(__uuidof(Excel::Application)))) // This is where we get the CLSID.
      {
         // Do stuff with the application pointer
      }
   }
}

HTH!

Thank You very much
But can you please tell me that how to get the IID our we get it in the similar manner.
m_pIDocument.CreateInstance(__uuidof(Excell::IApplication));

Stuart Dootson26-Aug-09 23:07

26-Aug-09 23:07

IID? For the interface? That's determined by the interface pointer class you're using to create the instance. In my example, the IID will be the IID of Excel::_ApplicationPtr, which can be accessed using __uuidof(Excel::_ApplicationPtr), IIRC.

Hi,

I have done my code this way
hr = CoCreateInstance(__uuidof(CADFilter::NW_Document),
NULL,
CLSCTX_INPROC_SERVER ,
__uuidof(CADFilter::NW_IDocument) ,
(void**)&m_pIDocument );

But the issuse is I am getting a message box getting pooped up while running the application.
And when I comment my change there is no such issue

For a start, what does the message box say?

Also - if m_pIDocument is a smart COM pointer which is of interface type NW_IDocument underneath, then this code is more idiomatically correct:

m_pIDocument.CreateInstance(__uuidof(CADFilter::NW_Document), CLSCTX_INPROC_SERVER);

Hi,
Following is the code I am trying to do

AcRx::AppRetCode acrxEntryPoint (AcRx::AppMsgCode Msg,

int cindex;

CADFilter::NW_IDocument *m_pIDocument;
CLSID clsid;
CoInitialize (NULL);
HRESULT hr = CLSIDFromProgID(LPCOLESTR("NW_Document"), &;clsid );
hr = CoCreateInstance( clsid, NULL,CLSCTX_ALL , __uuidof(CADFilter::NW_IDocument) , (void**)&m_pIDocument );
if(SUCCEEDED(hr))
{
AfxMessageBox(_T("Hi"));
}

}But I am getting an " HRESULT hr as an "Invalid class string"
