I have created a toolbar . Now i need to deploy it over the net . I have used two dll files created in the .net framework . I created a cab file which is referenced through the codebase object in the html page . Now when this page is referenced, the inf script is interpreted and the dll's are copied to the mentioned directories and the necessary entries are made . How do i register these into the assembly cache . When i do it manually i use the gacutil and the regasm . But what is the method for doing this while deploying over the internet using a cab file . in the inf file can i mention a batch file to be executed or a dos command to be executed . I heard that the dll's can be built to register themselves . Is it true . If so how di i do it .
Please Help

I've done this by using VariantToSystemTime to pick apart the DATE type, then set the corresponding members of a DBTIMESTAMP from the resulting SYSTEMTIME structure.

Hello sohailkadiwala,
Does the BSTR contain a date in string format or does it contain the binary data of a date ?

Hello Lim Bio Liong
Well It does contain date in string format.
(actually i am using dd/mm/yyyy format in the BSTR)
There is a MFC Class but i am creating component for use with ASP page
Hence i have no support for MFC and the component is loaded InProcess.
So buddy, i am passing date from asp page to my component which is accepted in a BSTR
This BSTR contains date in dd/mm/yyyy format and i want to convert it into DATE.

Hello sohailkadiwala,
I think the function to use is VarDateFromStr() (#include <oleauto.h>). This function is for general OLE Automation support and its use is not confined to MFC apps alone.
I've written a simple ATL object with a method BstrToDate() :
STDMETHODIMP CDateTimeConversion::BstrToDate(BSTR date_string, DATE *date_value_receiver)
{
// TODO: Add your implementation code here
_bstr_t _bs_t_date_string(date_string, true);
return VarDateFromStr
(
(OLECHAR *)_bs_t_date_string,
(LCID)LOCALE_SYSTEM_DEFAULT,
(unsigned long)(VAR_DATEVALUEONLY),
(DATE *)date_value_receiver
);
}
I've also written a sample client app as follows :
void main()
{
::CoInitialize(NULL);
if (true)
{
IDateTimeConversionPtr spIDateTimeConversion;
BSTR bstr_date_string = _bstr_t(TEXT("04/11/2003")).copy();
DATE date;
spIDateTimeConversion.CreateInstance(__uuidof(DateTimeConversion));
spIDateTimeConversion -> BstrToDate ((BSTR)bstr_date_string, (DATE*)&date);
if (bstr_date_string)
{
::SysFreeString(bstr_date_string);
bstr_date_string = NULL;
}
}
::CoUninitialize();
}
If you need, I can email to you the full source codes to my ATL object and my sample client. Let me know your email address.
Best Regards,
Bio.

Thanx buddy
Wel i'll try out this function today. If i need i'll let you know about your source code.
BTW my mail id is sohail_k@lycos.com

convert the BSTR to _bstr_t or LPCSTR and then pass the string to a COleDateTime , see MSDN for COleDateTime help.
it's not so hard. good luck.

Hi there
Copy your BSTR Object into CComVariant
like
BSTR bstrobj;
CComVariant var(bstrobj);
use this method
var.ChangeType(VT_DATE);
this will convert your var which is holding bstr data to Date type data ,condition applys :BSTR must not hold malicious  data
Now u can dine and date with your BSTR..objs.

Hello,
I created 2 .net dlls using C# and visual studio.net. One of the dlls (DLL1) references the other (DLL2).
I then create a .net exe (windows forms) which referenced both the DLLs.
I registered DLL1 with my system com+ services using regsvcs.exe. This was created as a server application with maximum access rights given.
I then created a proxy (proxy application) and deployed it on one workstation along with the .net exe.
When the exe file runs it is able to access DLL1 on the server. But DLL1 is not able to access DLL2.
To overcome this i registered DLL2 in the GAC but the problem was still present.
I want to know whether user created COM+ dlls can access other user created dlls on the system. If so how to do this.

does anyone have any experience in this?
I am using a CRecorset (C++) object to pull data from a database. The data field in the recordset is a CTime data object. I am trying to pass the data to a class defined in VB and the property is a Date data type.
Any pointers would be greatly appreciated.
thanks
roger

We have an .NET service (written in C#, running in the LocalService account), which impersonates an account, opens a CDO session and then reads/writes mails and tasks from/to folders only accessible by the impersonated user.
If the service calls windowsImpersonationContext.Undo() after the CDO session has logged on, it usually can read public folders and their content without a problem. But every once in a while (average after 20 objects have been read), it throws a System.NullReferenceException at System.Runtime.InvokeDispMethod.
If the service does not undo the impersonation and runs in the account which is logged on to Exchange, the NullPointerException is thrown exactly when the fourth CDO object is retrieved. I have already tried opening a new session before opening a folder, but then the Exception is thrown while logging on the fourth session.
If the fourth action is reading the contents of a folder, the NullreferenceException occurs in MAPI.Folder.get_Messages(). If I try to read a message, it occurs in MAPI.Message.get_Text(),
MAPI.Message.get_Attachments() or another get-method.
Here is a typical stack trace for reading message properties:
System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
at System.RuntimeType.InvokeDispMethod(String name, BindingFlags invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32 culture, String[] namedParameters)
at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr, Binder binder, Object target, Object[] args, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParameters)
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
at MAPI.Message.get_Attachments()
at Vita.Bk.SecureItem.CopyFrom(Message message)
And here is a typical stack trace for listing folder items:
System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
at System.RuntimeType.InvokeDispMethod(String name, BindingFlags invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32 culture, String[] namedParameters)
at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr, Binder binder, Object target, Object[] args, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParameters)
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
at MAPI.Folder.get_Messages()
at Vita.Bk.OutlookService.OutlookService.ListUserTodoItems(Object[] parameters) in c:\visual studio-projekte\mba kataster\outlookservice\outlookservice.cs:line 529
That is how the service behaves on .Net Framework 1.0 without service packs. I have installed Service Pack 2, now the NullReferenceExceptions always occur at random, no matter if the service is still impersonating a user or not.
The "Outlook EMail Security" stuff has been configured to allow all MAPI and CDO actions, but there is still no change, the CDO objects are throwing Exceptions after a while.
Does anyone know what happens here? Is is a problem of CDO or .NET Interop?
Thanx in advance,
corinna

We get a similar situation with our ASP.NET site that uses CDO to access our Exchange server. I never have figured it out and usually just "kicked" it to get it going again (kill the ASP.NET worker process). I'm betting it's a similar issue...except we don't use interop. At least, not directly. But we don't use impersonation, either. ASP.NET uses the System.Web.Mail namespace classes, which do use CDO. I'm guessing this problem is with CDO.
As far as configuring the Outlook email security, this shouldn't affect anything. They only affect MAPI, not Extended MAPI (or CDO, which seems to use some EMAPI).
I wish I could be of more help, but like I said, I never figured it out myself.

i compiled a atl project to implement dhtm binary behavior by vc6.0.
but, the error, 'IElementBehavior' : base class undefined, had appeared.
i included mshtml.h in my project.but i find that the interface 'IElementBehavior' is not in it. why?help me.thanks.

Are you sure your INCLUDE path is setup right? Sure, it is supposed to throw an error when a header file isn't found, but one never knows. Are you sure you have the latest Platform SDK? I have the most recent PSDK and IElementBehavior is showing up in my mshtml.h header file.
If all you have is the PSDK that came with VC++ 6.0, chances are you don't have it. Go to http://www.microsoft.com/msdownload/platformsdk/sdkupdate/default.htm[^] and update the PSDK on your machine. This could take a while, so make sure you have a fast connection or get the CD, in which case you pay only for S&H.

Hi guys,
I'm pretty sure what I'm going to ask is impossible, (I can't think of a way round it), however I'm trying to write a program which can get past a software firewall (outgoing) on a local machine (I KNOW there is not much you can do if someone has a linux firewall on a remote machine). Is there anyway to defeat software level (ie ZoneAlarm) packet filtering.
The reasoning behind this request is a program for stolen computers to report back to a server.
regards,
entr0py

I have an application which represents the filesystem of a device connected via a serial link. I do navigate the device's filesystem and copy files to/from using drag/drop or clipboard. Here comes the problem. I implemented Drag/Drop and Clipboard using CF_FILEDESCRIPTOR and CF_FILECONTENTS with IStream. But i donno how to copy the nested folders from the application to the Windows Explorer. Should i enumerate the contents of folder and all itz subfolders? It can be timeconsuming over the serial link. 
Somewhere i read that 'IStorage' can be used for the purpose. But how ?  No information or examples regarding "how to implement IStorage" is not available. Can anybody help me to solve out this, pleeeeeeeease?

 Our applicatiosn hosts the WebBrowser control. I need to catch the onclick event on a web page from our application.I am able to catch the onclick event except for frames in my handler in the event sink. When I click on a frame in a webpage, I am not able to get the onClick event to be handled in my code. Can anyone tell me why it is behaving this way?
