Hello,
I have a COM+ application built using C# and the MSI for it runs just dandy, its basically a COM proxy for .NET to ASP. However, when running a test VBScript, I get the following message whenever I attempt to execute one of the methods (object seems to get created though)..
on this line: set objCreditAppEntity = objComProxy.GetSavedApplication(1, "CITDE")
with this message: Error retrieving certificate with ID <> from location LocalMachine
and this stack trace:
System.Configuration.ConfigurationException
Stack Trace:
at CIT.EAI.Crypto.CertificateManager.RetrieveCertificateFromStore(X509CertificateStore store, String keyIdentifier)
at CIT.EAI.Crypto.CertificateManager.GetDefaultCertificate()
at CIT.EAI.Web.Security.WseUtilities.GetClientToken()
at CIT.EAI.Web.Security.WseUtilities.ConfigureProxy(WebServicesClientProtocol protocol)
at CIT.EAI.EFCanada.ComProxy.RepositoryFactory.GetCreditAppWS()
at CIT.EAI.EFCanada.ComProxy.EFCanadaComProxy.GetSavedApplication(Int32 creditAppId, String applicationCode)
Any ideas why? seems to be a WSE thing, but I'm lost as I'm still kind of a newbie to COM, etc...This proxy talks to three web services by the way.
VBScript test code given below
----------------------------------------------
Dim objComProxy
Dim arrContact
Dim errCode
Dim objCreditAppEntity
Dim objCreditAppEntityList
Dim objQuoteEntity
Dim objQuoteEntityList
dim xmlDoc, sPath, sFile, sInFileName
Set objComProxy = CreateObject("CIT.EAI.EFCanada.ComProxy.EFCanadaComProxy")
'ERROR HERE
set objCreditAppEntity = objComProxy.GetSavedApplication(1, "CITDE")
WScript.Echo "Credit app ID: " & objCreditAppEntity.CreditAppId
WScript.Echo "Credit app status code: " & objCreditAppEntity.CreditAppStatusCd

Is the COM dll registered? worth trying regsvr32.exe to register it.

Did you made a COM DLL?

Hi,
I have created a Dialog based application in VC++ 6.0(Client) and an ATL COM component (Server).
But I dont know where and how to invoke the interface in the client. Can any one explain how to make use of ATL COM server in dialog based application(client).
If not at least provide me a url where I can find details of creating client for ATL COM in VC++ 6.0.
Thanks

Well, you have to:
(1) initialize COM, calling CoInitialize
(2) create an instance of you object, calling CoCreateInstance
(3) (optionally) ask for another interface
(4) call your interface methods

Need to create moniker that handles path strings like "./boe2.xml" and "file:///d|/boe2.xml".
I've used MkParseDisplayNameEx() in my IBindHost::CreateMoniker() implementation and it works for the second type of pathes, but doesn't handle first type. I've tried CreateFileMoniker but it doesn't work too. What should I do?

Hi to All,
I am creating COM Wrappers(CCW's) to the existing .Net Product, which is developed using C#. In this, am getting problem with setting "Item" propertty as the Default Property. My requirement is like this:
I created 4 classess in CCW namely: PdfDocument, PdfForm,PdfFormField and PdfFormFieldList. to the respective .Net classess. Below, am giving the classess in brief. I configured my project for COM Interop .
*****************************************************************************************************************************************
PdfDocument:
public class PdfDocument
public readonly property Form() as PdfForm
get
''''''' code for returning PdfForm type
end get
end propety
end class
PdfForm:
public class PdfForm
public readonly property Fields() as PdfFormFieldList
get
''''''' code for returning PdfFormFieldList Type
end get
end property
end class
PdfFormFieldList
public class PdfFormFieldList
default public readonly property Item(byval pdfformfiled as PdfFormField) as PdfFormField
get
''''' code for returning PdfFormField type
end get
end property
end class
*****************************************************************************************************************************************
Using the above 4 classes, I want the behavior like below in classic ASP.
Code in classic ASP:
dim doc
set doc = server.createobject("DynamicPDF.PdfDocument")
''''' Instead of calling: doc.Form.Fields.Item(("name of the Pdfformfield")
response.write(doc.Form.Fields("name of the Pdfformfield")
Same code in VB6
dim doc as new PdfDocument
''''' Instead of calling: doc.Form.Fields.Item(("name of the Pdfformfield")
msgbox(doc.Form.Fields(("name of the Pdfformfield")
In Vb6, "Item" porperty is working fine. But, it is not working in classic ASP as a Default Property.In ASP, it is working fine only when I code like: doc.Form.Fields.Item(("name of the Pdfformfield")
I need your help in this regard.

Hi, I'm trying to bind an acccordion control to an access database, but nothing is displayed. I can't seem to find the problem. Plz have a look:

Is this a repeatable error? Does it happen every time or was it a one time occurence?

This is certainly kind of a newbie question, but I have a fairly old COM application server, that is used by VB and VC6 source code so far.
Now I would just like to use that app server again, but this time through .NET (C# in this case) since noone wants to keep that old VC/VB IDEs when developing new stuff. 
But I cannot find any good tutorial how to start with COM and .NET
Maybe I am just too stupid that I have not found any good article on it... help appreciated.

Hi Everyone,
Actually I like to use the GPL MPEG1/2 decoder from the follwing site
http://www.free-codecs.com[^]
I have the decoder source which gives GPLDec.lib and GPLDec.ax files. I had registered the GPLDec.ax file so that I can see that in Graphedit,but can anyone tell me how do I include the GPL MPEG1/2 Decoder in my own graph with the help of the IBaseFilter interface? And also the CLSID mentioned in the source is "CLSID_GpgMpegDecoder" ..When I try to add this with ADDFilterByCLSID(...) function I an getting a "Undefined Symbol" error as there is no header file given to access the GPLDec.lib file. So can anyone help me with this?
Thank You,
With regards

Dear all,
Good Day!
I’m writing a windows service(Login with local system) that open a Ms Word document, do some modification and then save the document to a new doc file. I’m using the Microsoft Word 11.0 Object Library (Office 2003) via interlop. It works fine in my XP development PC(VS 2003 , framework v1.1.4322).
However, when deploy it to Windows 2000 Server which have Office 97 installed, the following error message encountered when the system perform Word.Document.Open() function.
'System.NullReferenceException: Object reference not set to an instance of an object.
at Word.Documents.Open(Object& FileName, Object& ConfirmConversions, Object& ReadOnly, Object& AddToRecentFiles, Object& PasswordDocument, Object& PasswordTemplate, Object& Revert, Object& WritePasswordDocument, Object& WritePasswordTemplate, Object& Format, Object& Encoding, Object& Visible, Object& OpenAndRepair, Object& DocumentDirection, Object& NoEncodingDialog, Object& XMLTransform)
at GCMS.RWrite.WriteReminder(RObject oRem)'
The following is my code snipet:
Dim oMainDoc As Word.Document
Dim oApp As Word.Application
If IsNothing(oApp) Then
oApp = New Word.Application
End If
'Error encounter at this line
oMainDoc = oApp.Documents.Open("c:\Test.Doc", isible:=False, OpenAndRepair:=True, Revert:=True, ReadOnly:=False)
The following file are inside the deployment folder.
MSWORD.OLB
office.dll
stdole.dll
Will the MSWORD.OLB (version office 2003) conflict with the version office 97 at the deployment PC? Can anybody give me some advise
I have done some searching but still not able to find the solution  Some have suggested to use DCOMCNFG to fix the user profile problem but since the windows service is login as “System”, it shouldn’t have this problem right?

Hi,
Is it possible to share the same instance of a COM between multiple client ?
I try to implement this scenario :
----------------------------------
1 - Create a COM service with and interface ITest that open the RS232 port 3.
2 - Create an application that instance the COM and use ITest interface.
3 - Start the service (1).
4 - Start two different instance of the same application (2).
5 - From this two applications send data to RS232 port 3 using ITest interface...
I don't know if it's possible... If some one have a solution, send me a message
I found a solution to share memory segment from multiple instance of a DLL, but for hardware resource....???
Thanks,
Ps: A made the difference between RS232 COM port and Object COM :->...
