I demonstrated how to use Google in my response to your question below, perhaps you could try it for yourself first.

Is the answer XPATH
XPATH represents a range ?
did a word that correctly
|

No idea what that means, but it took one single Google search to find this article[^].

No idea, you need to read the article and any associated links for the details of how to do it.

Would anyone know where the put_visible method is documented
I think its part of the Excel :: Application object
|
|
|
|

Why not try this first[^]?

IVideoWindow is not part of the Excel programming interface Application, WorkBook, WorkSheet, Range ?

Is that a statement or a question?

I made a .NET COM DLL (VS2012, C#) it registers fine with regasm, but not with regsvr32. Also when I add the .tlb into installer and extract the com stuff (Installshield 2012) there is no registry entries after I have ran the installer. DLL is 32-bit and I'm using 64-bit Windows.
I have this on the code:
[ComRegisterFunction()]
public static void RegisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
RegistryKey ctrl = k.CreateSubKey("Control");
ctrl.Close();
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
inprocServer32.SetValue("CodeBase", Assembly.GetExecutingAssembly().CodeBase);
inprocServer32.Close();
k.Close();
MessageBox.Show("Registered");
}
[ComUnregisterFunction()]
public static void UnregisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
k.DeleteSubKey("Control", false);
k.OpenSubKey("InprocServer32", true);
k.DeleteSubKey("CodeBase", false);
k.Close();
MessageBox.Show("UnRegistered");
}
I've tried to find an answer to this but it seems nothing works.
Error with regsvr32 is:
the module "comclass.dll" was loaded but the entry-point DllRegisterServer was not found.
Make sure that "comclass.dll" is a valid DLL or OCX file and then try again.

There is a fairly strong clue in that message, regsvr32 needs the correct entry point to be in the DLL.

I've found atleast five solutions to this but none worked. I found that you can save the dll registry entries to reg file with "regasm /regfile:name.reg name.dll"
So I can just add the registry keys to installshield, I wonder if it does everything that regsvr32 does.

No idea, I'm afraid, but it would be easy to test.

Hi All,
I am using office 2007 interop DLL to create an Excel sheet in c#.NET.
when I tried to test my app on a machine with office 2003 installed I get an exception because of the version number of the DLL . How can I determine in runtime what version of office is installed and then load the appropriate interop DLL for that version ?
|
|
|
|
|
If you do not need features which became available in Office 2007, just use an interop dll for old versions of Office also when current Office is installed! A PIA created with Office XP still works with Office 2010.
Otherwise, you have to find out the registry keys of Excel...
|
|
|
|
|
Use DLL of office 2000. It may have less features but will work in all versions of office. If u need any extra features then try to avoid it or use a least version satisfying your needs.

Hi!

Sorry, my English sucks, I hope I can express clearly.i want to add a bar to the windows explorer,after a long time searching,i'v made a bar using BandObjectsLib(a C# library) and added it in to the Explorer window.but i have to open it through "Menu-View-Explorer bar",and the bar also came out in IE :<.my question is how to make it opened automaticly when Windows Explorer is opend.Or any other way to do this,i want to add a big horizontal bar actually a region in the bottom (or somewhere else) of Windows Explorer,so i can put my code and usercontrols into it.i use C#,vs2012,windows 7.thank you!

I've just been handed the task of replacing an existing COM component.
It has to stay as a COM component as we have no ability to change the caller.
It has to able to call a COM component, that again we can't alter. i.e. where changing the middle part of an existing process and have to do so transparently.
I've been doing some background research, and it looks like I can create a .NET COM component easy enough.  I've got a few q's though.
When you create the COM interface and class they have GUID's, do these GUID's have to match the existing COM component? Or is it when the caller makes the COM call the OS determines the component based on name?
Another requirement is that the final COM call is 'dynamic' in that the method name we have to call might change, assuming the method will act on the same data is this doable?
|

To differentiate between various COM components and Interfaces, GUIDs have to be unique. They should not match other COM components.
Didn't understand your requirement of "final COM call is 'dynamic'"
|
|
|
|
|
Thanks,
Regarding the last bit, I have to call another third-party COM component. But as the third-party app might be replaced, if possible I'd like to be able to configure the name of the component and method called? (assuming the new and old method are similar in parameters etc)
|

There are two scenarios:
1. Replace the 3rd party COM component and consequently use a different COM Interface (with a different signature).
This scenario is independent of COM programming. I would use Adaptor design pattern for this problem.
2. Replace the 3rd party COM component but use same COM Interface (i.e. the Interface's GUID is same).
In this case there will be no change in your program. All you need to do is to unregister the old COM server and register the new COM server.

Using C++ I want to discover which interfaces can be obtained from calls to QueryInterface() off a given COM interface I didn't write in the first place.
This old and brief CodeProject article seemed to provide a solution:
How to find the name for interfaces implemented by a COM object[^]
But its code fails to find interfaces that I know to be supported for sure.
I have only superficial knowledge of COM and could use the advice of experts.
Thanks in advance.
