One other way if you want to separate your design code from the runtime code (common in the .NET FCL with the .Design assemblies), attribute your class with a Type string for a ControlDesigner[^] in a different assembly so that your Type string would look like "MyNamespace.Design.MyControlDesigner, MyAssembly.Design" (".Design" isn't necessary - just a common naming convention). The ControlDesigner lets you paint over your control (see ControlDesigner.OnPaintAdornments.

The designer classes and interfaces can be very powerful when used effectively, and most designer support is built right into the .NET FCL (some is provided by the development environment like VS.NET or SharpDevelop). For more information about extending components with design-time capabilities, see Enhancing Design-Time Support[^] on MSDN.

FileAttributes

How can i change the fileattributes of a file (or folder). I will change the Read-only, Hidden, archive,... tags but i can't find it somewhere.

It was no problem to change the creation, last access and last written time, but that class (FileInfo and DirectoryInfo) doesn't have anything to change the attributes of it.

Can you help me?

Hi Jonathan.

Try the System.IO.File.SetAttributes()[^] static method.

See FileInfo.Attributes (inherited form FileSystemInfo). You can use bitwise operators to change the flags. For instance, to exclude the read-only, hidden, and archive flags, you could do something like this:

FileInfo info = new FileInfo("path");
info.Attributes &= ~(FileAttributes.ReadOnly | FileAttributes.Hidden
  | FileAttributes.Archive);

I want to replace the System Clock ("Date & Time properties") in the sys tray with my own. Does anyone have any ideas on how I can get text to appear as the notify tray icon (just like the windows system clock) ?

hello! help for SMSC class

10-Mar-04 6:26

Unless you can fit readable text into a 16x16 pixel icon, you can't. The system clock is not a systray icon and is handled specially by Windows.

I've gor the code to send SMS, but it gives an error message! Please any centilmen can help ? Wink | ;)

)

The code is as follows:

SMSC objSmsTool = new SMSC();
objSmsTool.PortID = 1;
objSmsTool.MessageText = "Hello, this is a test message";
objSmsTool.Recipient = "0624896641";
objSmsTool.ProviderDialString = "0,0653141414"; // The SMSC provider
Console.WriteLine("Sending message...");
objSmsTool.SendMessage(-1);// -1 means: through service provider
if( objSmsTool.LastError == 0 )
{
// YES, connection established.
Label2.Text = "ok";
Console.WriteLine("Message successfully delivered");
}
else
{
Label2.Text = "Message delivery failed, error: " + objSmsTool.LastError;
}
}
catch(Exception b)
{
Label2.Text = "exception";
}

Why don't you tell is what the exception is, and where it's occuring? Since this is not a .NET class provided by the Framework class library (FCL), it's difficult to know what you're doing wrong since this is a third-party control. You should always provide error information when asking for help on an error anyway.

It appears that the SMS assembly can't be found. You should put this either in the bin sub-directory of your web application or install it into the GAC by dragging into %windir%\assembly or using gacutil -i theAssembly.dll (only referencing the SMS assembly).

Anything beyond that, you should consult the web site for the SMS assembly you're using.

Interop with MSDev from a C# application

Hello !

I'm writing an application in C# that must be able to look for information in MSDev if at least one MSDev process is running.

Precisely, I'd like to get the list of the files that are currently opened in the MS-Dev editor.

I think I must add a Reference such as : COM / Visual C++ Text Editor
But I don't know how to use the component...

Does anybody know the right way to do that ?
Best regards,

Write click on Referenes in your project, select Add Reference then from COM tab browse your dll then simply you can add namespace and use it.

Thanks Mazy, but that's what I've done and the problem is that I don't know how to use this dll/namespace so as to connect with an MS-Dev process running on the same computer and to get the list of the files which are opened in MS-Dev using COM. D'Oh! | :doh:

If you're looking to write a plug-in, you can reference EnvDTE. You can find more information about this on MSDN, Manipulating the Development Environment[^]. More easily, just create a new add-in project in VS.NET. You can get access to the open files (the text editor itself won't help) from there.

If you're trying to do this external the development environment, I'm not sure how you could get a reference to the EnvDTE object or if it's even possible. I do know that devenv.exe does register open files in the running object table (ROT). You could P/Invoke GetrunningObjectTable to get a reference to the IRunningObjetTable (a COM interface, so you'll have to import it or re-define it in C#). You can then enumerate the objects using the EnumRunning method with an IEnumMoniker (forunately, .NET already exposes the UCOMIEnumMoniker interface so you don't have to define IEnumMoniker). From there, you can get file monikers, filtering on devenv.exe to get the open documents. COM programming experience will be helpful.

Actually I'm trying to do this from a standalone C# application other than Visual Studio (so it's not an add-in).
I'd like to connect with the MSDev.exe process (if one exists) through a COM interface I guess.
I've heard about ITextDocument, ActiveDocument, etc... but I don't know how to reach these interfaces or even if they're the ones I must try to get.

I wish I could find an example of 'communication' between MSDev and a .NET application because I don't know much about COM D'Oh! | :doh:

Anyway thank you,

Heath Stewart10-Mar-04 9:57

In order to get those properties, you must have a reference to the DTE object that the environment exposes. All those interfaces are contained in the EnvDTE assembly. While you won't be making a plugin, you'll still need that to get the objects and their properties within the environment. There is no way to get a reference to the DTE object with the information provided by the Process class.

You could, possibly, use Marshal.GetActiveObject("VsmIDE.DTE") to get an instance of the msdev.exe DTE object (msdev.exe is for Visual Studio 6, where devenv.exe is for VS.NET 7.0 and 7.1 currently), casting that to a DTE variable (if the process is alive, in which case it adds a moniker to the ROT). This may work, but it's untested.

It seems to be that... using System.Runtime.InteropServices;
But I'm quite lost since I'm not pretty familiar with COM functionnalities.

So I want to get the DTE for Visual Studio 6 and when I write :

object O = Marshal.GetActiveObject("VsmIDE.DTE");

... I get a COMException saying "Invalid class string".

If you had any idea to help me to solve this issue, I'd be really glad !

Sorry, seems to be that I gave you the ProgID for VS.NET. The ProgID for VS6 is MSDEV.APPLICATION. Once you get the object from the ROT, you'll need to cast it to DSSharedObjects.IApplication. You can get this by running "tlbimp.exe DEVSHL.DLL", which will create an interop assembly called DSSharedObjects.dll. DEVSHL.DLL can be found in the same directory as MSDEV.EXE. The DTE object is apparently not available in the same way as it is for Office and VS.NET.

Impressive... I probably would never have achieved that without your obliging help.

It works well and once you get this DSShareObjects dll, it's quite plain (especially thanks to auto-completion).
Even no need to use variants or things like that !

May I ask you a last question ? If there are more than one MSDev process in the ROT, how to get the list of their ActiveObjects (in order to choose one in particular for example) ?

I wonder why there aren't some pragmatic articles about interoperability with main windows apps :
- Use of InteropServices (Marshal.GetActiveObject, etc)
- How to get the ProgID of applications ? (strings like "MSDEV.APPLICATION")
- Which dll to convert from COM to .NET ? (like DEVSHL.DLL)
(By the way I don't know what is a moniker)

Summary :

...
using System.Runtime.InteropServices;
using DSSharedObjects; // generated with : tlbimp.exe DEVSHL.DLL
...
try
{
	object ObjetActif = Marshal.GetActiveObject("MSDEV.APPLICATION");
	DSSharedObjects.IApplication App = (DSSharedObjects.IApplication)ObjetActif;
	DSSharedObjects.IDocuments Docs = (DSSharedObjects.IDocuments) App.Documents;
	foreach ( DSSharedObjects.IGenericDocument D in Docs )
		comboBox.Items.Add(D.Name);
}
catch(COMException) { /*No MSDev running*/ }

I'm grateful to you.
