i'm using the reference Microsoft.Office.Interop.Visio to create a visio drawing document. When trying to obtain a visio application in my c# program as follow : "Application application =new Application()", i got the error below:
 
La récupération de la fabrique de classes COM pour le composant avec le CLSID {00021A20-0000-0000-C000-000000000046} a échoué en raison de l'erreur suivante : 80040154 Classe non enregistrée (Exception de HRESULT : 0x80040154 (REGDB_E_CLASSNOTREG)).
 
When using the same type of reference such as "Microsoft.Office.Interop.Word" or "Microsoft.Office.Interop.Excel" everything works properly. Any suggestion on how to address this issue will be really appreciated. Thanks!!

15-Jun-14 23:42

The message is clearly telling you what is wrong: Visio is not installed on your system.

16-Jun-14 23:15

Thanks for your reply.
I have visio installed on my system trough Microsoft Virtualization application.

That is why, the COM for visio is not found comparing to the COM for Word or Excel which i directly installed on my system(locally installed).

How to access visio objet which is installed on a virtual server as it is my case from my c# program.

Any idea! Thanks

16-Jun-14 23:21

Well, as the message clearly states, Visio is not installed on the system that you are trying to access it from, so you have no choice but to install it. The real system and the virtual system are totally separate entities.

16-Jun-14 23:38

Ok, since it's still a Microsoft technology (i mean the virtualization application for software ), is there any way to access Visio without having to install its on my real system?

The fact is that the application Virtualization is an application streaming solution and i run visio manually without any issue.

Thanks for your interest and constribution Smile | :)

No, As I said before the two systems are entirely separate; it is the same as having two different PCs.

IFileSaveDialog / Filename using C++

17-Jun-14 3:12

I installed a visio trial version and everything works perfectly! Smile | :)

Thus i will need to locally install visio on each sytem of my network instead on having its installed on a server and using client app to acess its in order to run my soft. This is the issue actually.

Anyway, thanks for your valuable contribution.

Where can I update the edit field to reflect changes of the file name to save?

I have customized my save file dialog and use CFileDlgEventHandler. There i need to set a different filename.
In the file save dialog I select a filename from existing files, e.g. blah.tif. After clicking a custom checkbox I need to set e.g. blah_C1.tif. I can get and set the filename inside the handler:
CComQIPtr pDlg = pfdc;
pDlg->GetFileName(...) and pDlg->SetFileName(...) work,
but after clicking 'Save' I get the filename previously selected (blah.tif) and not the changed one.

Anyone out there with a tip to update the edit control behind the scenes?

A bit of a guess, but have you tried IFileDialogCustomize::SetEditBoxText method[^]?

jung-kreidler

23-Jun-14 21:17

Thanks. Tried it, but without positive result.

The problem is, that the filename is saved anywhere else behind the scenes (comdlg32.dll?). Changing the edit box does not help.

Hi, All

How to create a simple COM component in C++, and then to consume it in my C# project.

I don't want to use ATL. Are there any simple step by step instructions or a complete procedure to get started. (I have done googling but not found any desired content).

Any help will be appreciated.

Setting up the COM+ Identity using C# Code

Juan Topo

19-May-14 8:50

Hello, I recently started programming with COM Objects Catalog using C-Sharp.

In principle, everything turned out pretty simple and I managed crar COM objects, install them and make them visible from the console, register and configure some properties of automatic way.

However I am with some problems as it relates to the configuration of some properties, namely:

While I can configure the identity component, either as INTERACTIVE USER or a specific user, I could not configure the identity of the COM + application with the Auditors Local System (Local System, Local Service and Network Service)

I do this as follows:

            Boolean resultado = false; ;
            ICOMAdminCatalog catalog;
            ICatalogCollection applicationCollection;
            ICatalogObject application;
            int applicationCount;
            int i;
 
            try
            {
                catalog = (ICOMAdminCatalog)new COMAdminCatalog();
                applicationCollection = (ICatalogCollection)catalog.GetCollection("Applications");
                applicationCollection.Populate();
                applicationCount = applicationCollection.Count;
                
 
                for (i = 0; i < applicationCount; i++)
                {
                    application = (ICatalogObject)applicationCollection.get_Item(i);
                    
                    if (application.Name == nombreApp)
                    {
                        application.Value["ApplicationAccessChecksEnabled"] = false;
 
// Interactive User:
 application.Value["Identity"] = "Interactive User";
                                applicationCollection.SaveChanges();
 
//Specific user:

 application.Value["Identity"] = txtUsuario.Text;
                                application.Value["Password"] = txtClave.Text; 
 
//Save Changes

 applicationCollection.SaveChanges();
 
            }
 
            catch (Exception ex)
           {
                resultado = false;
                MessageBox.Show(ex.Message);
            }
        }

Can you think how to configure the Local System Account? I tell them that if IDENTITY indicated in the following:

@ "nt authority \ LocalService"

and PASSWORD "" (empty)

Everything goes well, but in reality is set to a specific user with the supplied information.

From already thank you very much! Laugh | :laugh:

VB6 to .Net Interop issue

Sampath Sridhar

1-Dec-13 22:10

I am writing a middleware library in .Net which will be invoking Web services and respond back to VB6 legacy applications with the service output.
So far I have made the assembly as ComVisible without generating strong-name for it.
The .Net dll will be used to generate a type library (.tlb) which can be added in Project References of the VB6 application and used to invoke the services.

Using regasm tool, the TLB file is generated fine and registered to the local registry.

I first registered the TLB from local system drive and everything worked fine.

Now the system constraint is that, the assembly and type library cannot be stored in end-user machines.
So I need to map to a network drive and register the TLB from there.
The regasm tool registers it from network drive also, but the VB6 application is not able to access the classes in .Net

Command used: WINDIR%\Microsoft.Net\Framework\v2.0.50727\regasm <dllname> /tlb /codebase <network folder path>

Whenever i try to create new object, it is throwing error '430-Automation error. Class does not support the expected interface'.

So I want to know how to resolve this issue?

Callback From .NET Com Class to Delphi

I just can't seem to get this right.
I have a Com Class written in VB.Net that brings up a form where users can enter information.
I have a delphi program that opens this class and it shows the form fine.
The problem I have is with events raised in the Com Class. It just does not get fired in delphi, although I can assign it to a procedure.

Has anybody managed to do this?

Can someone help me on this please?

I am trying to load the

And for some reason I get the feeling the source of the error
Is its not finding the file
I tried various variations on the file name as just specifying the file and having it in a directory
That's in the path variable but I still get the same error

Thanks

I have not managed to find a decent explanation for either of the error codes you received. All I can suggest is that you test with a Unicode and ASCII version of the string, and be sure that the path to the file is correct.

Hello,
I'm trying to solve one problem with custom cred.prov. on win8.
The problem is that if you select any tile (e.g. my, custom) and you have CPUS_UNLOCK_WORKSTATION scenario - Logonui will dismiss it automatically after 1 minute. This is not relevant to CPUS_LOGON scenario. Selected tile will stay untill user press Ok or Cancel buttons.

So I'd like to ask, maybe somebody has worked with such thing already, is it possible to handle that moment when selected tile is going to be dismissed.

using debugging I found that IConnectableCredentialProviderCredential::SetDeselected() is not called when IConnectableCredentialProviderCredential::SetSelected() is called by selecting the tile.
