Hello,
I'm a fairly new to COM and web services, but am capable in C#. I've written test applications to consume some web services I've set up, but now I am to the meat of what I am writing...
I need to create a c# COM assembly (.dll) that a win32 program can use to access web services. The problem is, when I start a C# DLL project, it complains "[C# Error] Class.cs(9): The type or namespace name 'Services' does not exist in the class or namespace 'System.Web' (are you missing an assembly reference?)" when I try to add "using System.Web.Services;" as I did in the Win32 APP.
Is there a different resource to use for COM?
I'm sure I'm just missing something stupid, but I can't for the life of me figure it out...

If you have an avi-file you can simply put it in an html file via the object-tag like:
<object id="xyvideo" width="320" height="240" classid="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701" standby="Loading Media Player" type="application/x-oleobject">
<param name="width" value="320" />
<param name="height" value="240" />
<param name="FileName" value="xyvideo.avi" />
<param name="ShowControls" value="TRUE" />
<param name="AutoStart" value="FALSE" />

The above answer is very much correct if you have an avi file etc already saved somewhere.
Maybe you want to show the live video from the webcam in IE.
For that, you could do the following: (VC6)
1- Create a new ATL/COM project using Appwizard.
2- Insert New ATL Object->Controls->Composite Control.
3- Now you have a dialog, on which you can place controls, write code behind it, etc.
Hope that helps.
this is this.

Hi,
I want to make a call to IDispatch GetIDsofNames and IDispatch Invoke from one COM exe to another COM exe (in which the implementaion of these two methods is being done). The second COM exe is an automation wrapper. In doing so I want to pass an argument (BSTR) to IDispatch GetIDsOfNames and Invoke from the caller exe so that i can preserve my thread pool design. e.g I need to do the following
STDMETHOD (GetIDsOfNames)(REFIID riid, LPOLESTR* rgszNames, UINT cNames,LCID lcid,DISPID* rgdispid, BSTR sessionID );
STDMETHOD ( Invoke )( DISPID dispidMember, REFIID riid, LCID lcid, WORD wFlags, DISPPARAMS* pDispparams, VARIANT* pVarResult, EXCEPINFO* pExcepinfo,
UINT* puArgErr, BSTR sessionID);
Can some body tell me the exact signature to be used in my IDL for GetIDsOf Name and Invoke.

IDisptach is a starndard COM interface.
Some quick thoughts -
1. You can inherit your own dispatch interface from IDispatch and implement this interface instead
2. Add a property "SessionID" to this new IDispatch dervide interface
Have a great day ahead!

hello guys,
I am having a VB6 COM FTP application that is being called by some VBScript. It works perfectly fine in Windows based ftp server. However, one of the client is trying to use it in IBM Mainframe box (don't know the version yet) but it doesn't work. connection to mainframe occurs ok however when trying to put the file to mainframe it doesn't work.
The vb6 code is as below: In an ideal windows ftp environment I call it as:
myFTP.PutRemoteFile("c:\test.txt", "", "/MyFTPFoder") and it works fine.
However, the client has some funny naming convension of their mainframe file system. eg RemoteFolder is as F1.Test.ASL.Mne.FTS (they call it dataset)etc.
my questions are:
Is it a valid naming convension for the mainframe eg F1.Test.ASL.Mne.FTS?? or it needs to be mapped to a physical drive?
Is there any reason the ftp shouldn't work in mainframe while working in windows?
Thx

Hi,
I have an MFC based Document-View-Application with a CHTMLView hosting a IWebBrowser-Control. Futhermore I implemented an Event Sink based on a CCmdTarget to listen to MouseMove-Events (HTMLDocumentEvent) within the Browser-Control. This works fine for websites not working with frames. When I work with frames I only get connected to the frame-document itself.
Any help is truly appreceated.

I am new to COM. I am developing an application using COM. I got the error as: error LNK2001: unresolved external symbol _CLSID_WMRMKeys. What I know is that the com object is from a DLL, and I registered the DLL by running regsvr32 *.dll, and the registration is successful. Thanks for your help.

I presume you have included the header file for the dll in your application and everything looks fine until you link. I would recommend if you are new to com that you use the #import directive to access the dll's functionality (see MSDN) for more information.
The alternative would be to use include the yourdllsname_i_.c stub file in your project. Turning off precompiled headers on that file otherwise you'll get a weird "stdafx" not found error.
Using #import would be easier but ...

Hi Forum!
this is Shatrughan Mishra. I am thankfull to
you all as many like me would have been for the articles posted by you on
codeproject.com.
I have been trying to add two addins to the MS word 2000 and XP. Both
are working fine independently. But, the problem is when I try to add
both of them the one is overridden by the other and both produce the
same result. I also would like to learn about the mystery of ".dot".
Please guide me and help me solve my problem. If you charge anything for
this, I would be glad to pay for it.
Thanx in advance!
Regards!
Shatrughan.

Are the two add-ins using the same original code? I mean, did you create one project and made two copies, and changed the code in both the copies to create two add-ins?
If you did the above, then it will not work, as the GUID is the same for both. Then you should create new GUIDs using the GUIDGen.exe utility, and use them in at least one of the projects, so that they do not conflict.
And about the ".dot" stuff, sorry, I have never worked with that.
this is this.

There is an application with hosted Internet Explorer (WebBrowser). I have a problem with customizing
IE preferences. They are to be customized only for an instance of Internet Explorer without affecting
global preferences stored at HKCU\Software\Microsoft\Internet Explorer.
1. I need to specify default page, colors, CSS styles and font size. I use
IDocHostUIHandler::GetOptionKeyPath to specify registry path with custom preferences:
STDMETHODIMP rbDHTMLBridge::GetOptionKeyPath(BSTR __RPC_FAR *pbstrKey, DWORD dw)
{
MessageBox(NULL,"GetOptionKeyPath", "GetOptionKeyPath", MB_OK);
static LPCWSTR lpwszKey = L"Software\\MyApp";
if ((*pbstrKey = (LPOLESTR)CoTaskMemAlloc((wcslen(lpwszKey) + 1) * sizeof(OLECHAR))) != NULL) {
wcscpy(*pbstrKey, lpwszKey);
} else {
return E_INVALIDARG;
}
return S_OK;
}
Function is called by IE and returns S_OK. But it does not affect hosted IE: it uses global
preferences.
Why it didn't work? May be I missed some initialization?
2. I need to remove footer and header of HTML pages printed using hosted IE. It can't be done
by GetOptionKeyPath (Internet Explorer uses global preferences for footer and header in any case).
It can be done by WebBrowser.ExecWB(OLECMDID_PRINT, ...) as described in
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q267240. I copied code from this article into
my application but it didn't work. Footer and header from original page were used on the printed page.
Why it didn't work?
May be the reason is what i have IE6.0 but the highest version of IE in APPLIES TO section of the article is 5.0?
Any help will be appreciated.

Hello,
I was wondering if it is possible to implement MDI in a MFC based ActiveX control. I was able to implement SDI (using a sample from MSDN), but I faced some difficulties when implementing MDI. Any help would be highly appreciated.
Thanks in advance,

Hi,
I want to pass the reference(test) of the interface (ITest) define inside the COM DLL (TestCom.dll) in my application function.Example
GetMerchItemType( TestComLib::ITest &test, int Temp)
However I am facing the following error.
error C2653: 'TestComLib' : is not a class or namespace name
error C2061: syntax error : identifier 'ITest'
Can you please help me resolve this error.
Thanks

Check the spelling.
If you haven't explicitly renamed the namespace it would look something like 'TESTCOMLib'.

Hi everybody
I got some problems by using an application under Windows NT 4.0, this application uses OPC and it seems it's causing this kind of problem... it says RPC system not initialized... another weird thing is the request of the missing OCX of WinSock "mswinsck.ocx" that should come with the system (I took one on Win2K and registered by my own using REGSVR32... but I'm not sure it's a great idea...). If somebody know anything that may help please tell me!!!
Thanx

Hi, friends
I tried to build a dll which support COM self-regist using Visual C++ 6.0. I used a API, named LoadTypeLib, to load the dll's typelib:
...
CComPtr<itypelib> pTypeLib;
HRESULT result = LoadTypeLib(module,&pTypeLib);
...
The variable "module" is the DLL's full path name. For example, I use "D:\\temp\\test\\test.dll". But, the return value "result" always is 0x80029c4a (TYPE_E_CANTLOADLIBRARY). If I use "D:\\temp\\test\\test.tlb" as the value of "module", this function should return 0x00000000(S_OK).
I have import "test.tlb" into the resource of test.dll. So I don't know how to resolve this problem.
Thanks a lot!

Hello smallbluedemon,
1. Make sure that you have set the resource type to be "TYPELIB" and have also set the resource ID to be 1.
2. Try out the following function to load your resource-embedded type library binary :
HRESULT MyLoadTypeLibrary(ITypeLib** ppITypeLibReceiver)
{
TCHAR szFileName[_MAX_PATH];
memset (szFileName, 0, sizeof(szFileName));
GetModuleFileName
(
(HMODULE)NULL,
(LPTSTR)szFileName,
(DWORD)sizeof(szFileName)
);
// Need to concatenate a \1 to the end of the filename
// because we are acquiring the type library which is
// embedded as the 1st resource of type TYPELIB.
strcat (szFileName, "\\1");
return LoadTypeLib((const OLECHAR FAR*)_bstr_t(szFileName), ppITypeLibReceiver);
}
Use it in your code this way :
int main(int argc, char* argv[])
{
CComPtr<ITypeLib> pTypeLib;
MyLoadTypeLibrary(&pTypeLib);
return 0;
}
Pls let me know how things go 
Best Regards,
Bio.

Hello, Bio.
Thank you very much!
By your suggestion, I found my mistakes. In my resource header file "resource.h", I set following macro:
#define IDR_TYPELIB 199
But, I forgot to add this to file name. I add your statement:
........
GetModuleFileName(hInstance, ansiPath, MAX_PATH);
strcat(ansiPath,"\\199");
MultiByteToWideChar(CP_ACP, 0, ansiPath, strlen(ansiPath) + 1,module, MAX_PATH);
.......
Problem resolved !
Thank you again. Thank you very much!
Your sincerely
Remy (smallbluedemon)
