hi,
i'm trying to write a shell extension for printers in c#. i use the IContextMenu and IShellExtInit interfaces to insert the menu item in the context menu - it works fine. my problem is to find out to which printer the context menu belongs.
example:
i have three printers installed on my system.
1. name: hp 5p port: lpt1
2. name: hp 1160 port: usb001
3. name: local hostprinter port: lpt1
when i click on the 'hp 1160' printer and then on my context menu item the port of 'local hostprinter' has change to 'usb001'. to do this so i need to know the name of the printer... how can i do it?
thx

hi,
here is the IShellExtInit.Initialize to get the printername:
int IShellExtInit.Initialize(
IntPtr pidlFolder,
IntPtr lpdobj,
uint hKeyProgID)
{
try
{
uint CFSTR_PRINTERGROUP;
CFSTR_PRINTERGROUP =
DllImports.RegisterClipboardFormat("PrinterFriendlyName");
m_dataObject = null;
if (lpdobj != (IntPtr)0)
{
m_dataObject = (IDataObject)Marshal.GetObjectForIUnknown(lpdobj);
FORMATETC fmt = new FORMATETC();
fmt.cfFormat = CFSTR_PRINTERGROUP; fmt.ptd = 0;
fmt.dwAspect = DVASPECT.DVASPECT_CONTENT;
fmt.lindex = -1;
fmt.tymed = TYMED.TYMED_HGLOBAL;
STGMEDIUM medium = new STGMEDIUM();
m_dataObject.GetData(ref fmt, ref medium);
m_hDrop = medium.hGlobal;
uint nselected = DllImports.DragQueryFile(m_hDrop,
0xffffffff,
null,
0);
if (nselected == 1)
{
StringBuilder sb = new StringBuilder(1024);
DllImports.DragQueryFile(m_hDrop, 0, sb, sb.Capacity + 1);
string objectname = sb.ToString();
}
}
}
catch (Exception e)
{
sting err = e.ToString();
}
return 0;
}

Hi
I have a ICopyHook extension DLL. But this DLL is coming to effect only when i restart my explorer i.e, by lkilling the explorer.exe. If i register the DLL, i will have to kill the explorer.exe to make it work. Is there any way by which i can make the DLL work wihtout restarting the explorer.

Hi,
I made a COM-client in C++ which uses the import directive and
_COM_SMARTPTR_TYPEDEF(Iclogmanager, __uuidof(Iclogmanager));
to access the methods of the COM-Server via a smart pointer.
Iclogmanager is a dispinterface and the COM-Object which implements it is a Visual-Fox-Pro COM-Server. Its image is in an exe-file and it runs as a separate process on an other machine.
I was surprised to see, that the client crashed, after I released a new version of the server, although I did not even add additional methods. It was just a line of additional code I added within a method.
To be exact, it crashed at
HRESULT _hr = raw_doQuery(tcFilterMethode, toCollParameters, &_result);
After recompilation it worked fine again.
This is absolutely not consistent with my idea of COM.
Any idea?
Thanks an best regards
Werner

what is an interface ?
difference between interface and a abstract class >

Essentially an interface is an abstract base class, but their are limitations of what is allowed to ensure compatible vtable layout between different compilers:
- No virtual destructors (as different compilers implement it differently).
- Only single inheritance (as different compilers implement multiple inheritance differently).
Probably other stuff I forgot.

A interface is an abstract class in c++.it's methods are not defined.A interface shows some aspects of a com component (coclass) like we have "human" component then IHand and IMouth could be it's interfaces.

Hi,
I am trying to send a simple string from a ActiveX written in C++ and pop a messageBox out in VB .NET with this string in it. I have tried everything and spoke to many people about this problem.
When I attempt to run the VB Application I get a error telling me
System.Runtime.Services.COMException and with further detail it tells me it is a type Mismatch
I have written a sample program that has a simple function called GetString,
The MessageBox in the function GetString doesnt even pop up

The first thing that catches my eye is this line in the .ODL file:
[id(1), helpstring("method GetString")] void GetString(BSTR* str);<br />
This should read:
[id(1), helpstring("method GetString")] void GetString([out, retval]BSTR* str);<br />
Steve
-- modified at 22:00 Sunday 22nd January, 2006
ADDED:
The retval means you should be able to write something like this on the dotNET side:
<br />
s = obj.GetString()<br />
|
|
|
|
|
For dispinterface your note can be more simple:
[id(1), helpstring("method GetString")] BSTR GetString();
With best wishes,

hi,
i have developed a small compression C++ COM dll to use in Visual Basic and ASP. i wrote 2 simple functions in COM object
STDMETHODIMP Compress ( BSTR src, VARIANT * target );
STDMETHODIMP Decompress ( VARIANT *src, VARIANT *target );
Compress: receives a string src and compresses it , writes compressed binary byte array to target.
Decompress: receives compressed byte array as src and, writes decompressed string into target string object.
in visual basic all tests go well
Test Visual Basic Function:
Public Sub Test ()
Dim obj = Server.Create("XXX")
Dim str as String, target as Variant , str2 as Variant
str = "testtesttesttesttest" 'any test string
obj.compress( str, target )
obj.decompress( target, str2 )
Msgbox str & vbNewLine & str2
end Sub
My problem is in asp to call decompress() , in asp i get ms vbscript runtime error , err.No = 507
can anyone help for this, google didnot help me much for that
thanx

My Question is, I have a one dll in that dll contains so many classes, then now I want to export a call and then Import a call.
can you tell me thorugh the example.(How I can export and How I can Import).
Srinu
|
|
|
|
|
It depends on what you want to export and in some cases the the compiler used to do the exporting and the importing. If you just want to export a global function you need to look up extern "C" and __declspec(export) or use a .DEF file. With this technique the compliers used at the exporting and importing ends will not matter. If you want to export a class use __declspec(export) on the class. Using this technique the compilers at each side must use the same name mangling scheme. Or else you can use COM to export a COM object and the importer can be any langauge that supports COM. More information is needed before any more detailed help can be given.

I am new to COM and would like to get some information.
I need to create an active document server application.
I have some questions and I would be grateful if you can answer the following
1) Can I create a dll that is an active document server(either mini or full server)? if no, please specify why?
2) What do I need to need to get started with active documents and have complete understanding of what I am doing.
3) Can you point to some online resource which gives indepth implementation details about active documennts. All the links I found in google asked me to create first a skeleton application using wizard which I would to avoid so that I have complete know how of my code.
4) this question might seem stupid but its important for me. Is there any use of active documents other than that your application will not open in a separate window and will be activated inplace.
Thank you

Hi everyone,
I hope someone has idea on how to do this...
I used this example[^] to create a user control with windows controls with the idea of accessing the client's file system through internet explorer by using this interface as an ActiveX.
The basic idea is that through this control I access some files in a server through FTP that need to be updated, for example in c:\files\ in the client that's looking at this web page.
So, I navigate in IE to this webpage with this user control in the page, and it works ok in my working computer, but when I try to run this update in another computer, I get error messages stating that I don't have the priviledges to access the files in the computer.
Has anyone by any chance tried something like this? accessing the client's file system from IE using a user control?
My studies have brought me to the fact that it's possible to update these files:
- By setting this web site as secure in IE it works ok in other computers.
- By setting security priviledges with the .NET Framework configuration tool the control also works.
Well, what I need is that some how the user doesn't need to do any of these configurations, but somehow the user is asked if it allows the activex component to run and lets it work on his computer.
I've seen that some activex controls prompt if they'll be allowed to run, but for some reason this is not the case with this control.
Thanks for taking the time to read this

I am currently following a book on how to sign assemblies with strong names in order to register a serviced component in the into the COM+ catalog and some errors are occuring.
My AssemblyInfo.cs file currently looks like this: (of importance is the AssemblyKeyFile attriubte)
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.EnterpriseServices;
// General Information about an assembly is controlled through the following
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("StepByStep7_1")]
[assembly: AssemblyDescription("Retrieve and update data from the Northwind database")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("StepByStep7_1")]
[assembly: AssemblyCopyright("Copyright © 2006")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]
[assembly: ApplicationActivation(ActivationOption.Library)]
[assembly: ApplicationName("NorthwindCS")]
[assembly: AssemblyKeyFile(@"..\..\..\70320.snk")]
// Setting ComVisible to false makes the types in this assembly not visible
// to COM components. If you need to access a type in this assembly from
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]
// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("2d37557e-b619-4092-80e4-4a30e2978021")]
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the values or you can default the Revision and Build Numbers
// by using the '*' as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
When I build the application I get the following error:
Use command line option '/keyfile' or appropriate project settings instead of 'AssemblyKeyFile'
Can anyone help explain why this error is coming up? The build itself actually does succeed, however it is giving me hassle when I come to register the serviced component in the COM+ catalog. I am presuming that it is because of the error in the build?
I would be very grateful to anyone who can help in order that I may move on in the book as I have just got a second wind to return to my studies and want to make the most of it while it lasts!!!
Thanks
Paul

I've an ActiveX visible control, written in ATL. Different containers can run it.
Besides, I've a COM (MFC EXE) Server that being informed about any ActiveX properties changes. So I'd like to change the same properties in the other running ActiveX components. In other words all of ActiveX'es could change their properties synchronously.
Thanks.
