I'd like to determine how to programatically start/stop/pause the indexer from Microsoft Search.
I know it is possible because I've seen it done in programs like this one: http://brandontools.com/files/folders/sidebar_gadgets/entry511.aspx
However, I cannot find any docs on MSDN or anywhere.
There is a "Windows Search" service which can be controlled with traditional service control methods. However, starting/stopping this service also changes the availability of search itself. I want to control just the indexer.
Does anyone know where docs may be found that describe how to interact with the indexer? My search skills have failed me.
There isn't a way to simply disable the indexing part. It's an all or nothing service. The description of the WSearch service states:
"Provides content indexing and property caching for file, email and other content (via extensibility APIs). The service responds to file and email notifications to index modified content. If the service is stopped or disabled, the Explorer will not be able to display virtual folder views of items, and search in the Explorer will fall back to item-by-item slow search."
However, you might be able to control it through drive/folder properties ... from Explorer, you can switch it of for an individual drive (see the properties of a drive; there's an option "allow indexing service..."), or for a folder (folder properties -> advanced -> "For fast searching, allow indexing service...").
EDIT ... a bit of googling, and the above properties are available - if you look at the MSDN page for System.IO.FileAttributes, there's a property NotContentIndexed with the description The file will not be indexed by the operating system's content indexing service. I would assume that you should be able to set this on individual folders. I don't know if this works if set at the drive level (without a recursive run through the drive), but hopefully it'll give you a head-start on whatever you're ultimately trying to achieve.
According the Microsoft there isn't an official way of doing so.
Here is a great tutorial on programmatically interacting with Windows Search: article at JoyOfCode.
The Windows Search 3.x SDK provides a .NET API that works against Windows Search 3 or 4.
Unfortunately, it doesn't expose pause/resume. All of the index control samples I have found use WMI to stop the search service. That will stop indexing, obviously, but at the expense of search itself not being available.
It's an old thread, but I ran across it. Someone else might as well.
Use an AutoIT script to open the Indexing Options and click the Pause button in the dialog box.
Something like this:
ServiceController service = new ServiceController("WSearch");
service.Start();
or
service.Stop();
Open the "Run" Dialog (Start | Run), type(or copy)
%SystemRoot%\system32\compmgmt.msc /s
and unfold the last one

I am a bit of a beginner at InstallShield (in the sense that this is the first time I've used it!).
I have some code that I am packaging up in a .net DLL to check for the existence of anti-virus. The installer I am attempting to create must check for anti-virus (by calling a custom action using my DLL?) and cancel the install if none has been found.
The way I seen it working, was the user would see a dialog that is informational ("about to check for anti-virus"), the user would press "Next" it would call the custom action and then show a success screen with a "Next" button, or a failure screen with "Finish" button.
Is this sort of thing possible with InstallShield? Are there any good tutorials out there for doing this sort of thing?
Do you really need a custom action? Do you have more detailed requirements with regards to what products and versions you are looking for?
InstallShield / Windows Installer has a built in search pattern that can look for registry entries, files, et al.
If you really do need a custom action, how long do you expect the execution to take? If it's only a couple seconds, just schedule it to run after AppSearch. You don't need a UI to say "now doing blah" just do it.
Since you want to do this in .NET, you need to look at Windows Installer XML (WiX) Deployment Tools Foundation (DTF). You can use this to author/compile custom action DLL's that InstallShield can then consume. Generally the custom action should do it's search and then set a property based on it's result. Then use that property in evaluating whatever business rule you are trying to implement.
When automating excel using the Excel Interop API, I can easily do a range search using the method Range.Find. I am passing through the LookIn, LookAt, SearchOrder, SearchDirection, and MatchCase options for the Find. This as noted by the MSDN documentation, persists the values passed into this method into the user settings, so the next time that the user opens the find form, the options will be selected which I used in the Range.Find method.
I need to persist the values of the find options before and after I do the programmatic find. So I want to capture the current find options, then do the Range.Find, and then set the find options back to the options that were set before my search. However, I do not see that the find options are publicly accessible. Any ideas on how to get these?
I'm basically looking to retrieve current find option values for LookIn, LookAt, SearchOrder, SearchDirection, and MatchCase.
Update
The most interesting thing I could find so far is that you can access the Excel Application dialogs - Dialogs Interface. So here, I can get access to the FormulaFind dialog, which is slightly different than the Find and Replace dialog, though may lead to some of the properties I'm looking for. I haven't had any luck, but perhaps there's a way to access the properties through this form using reflection. I'll keep trying something with this.
// xlDialogFormulaFind, xlDialogFormulaReplace
Excel.Dialog dialog = this.Application.Dialogs.Item[Excel.XlBuiltInDialog.xlDialogFormulaFind];
Well, I am not sure if you'd consider this approach, but I'll give a shot here in case it might be helpful.
What I would do is, I'd create a registry key holding the values you wanted to persist. I could then call RegistryKey.GetValue(valuename) to retrieve values, provided that there's no exceptions thrown.
As long as that registry key stays there, unchanged, and you have enough privilege to access registry key, you should be able to always get the same values.
Wish we could really use application settings here, which would make it easier, but, well, as you might have known, vsto add-in doesn't like it, according to this article.
You cannot use application settings in an unmanaged application that
hosts the .NET Framework. Settings will not work in such environments
as Visual Studio add-ins, C++ for Microsoft Office, control hosting in
Internet Explorer, or Microsoft Outlook add-ins and projects.
Hope this helps.
Hopefully this question has a simple answer i'm overlooking! I have an IIS webserver with multiple sites on it. In Perfmon, they show up as w3wp#1, w3wp#2, etc... I'm writing a Logman script that will collect performance counter data using the counters/instances that I specify and I want to ONLY collect any w3wp worker processes.
I've tried a couple ways, but no luck:
\.NET CLR Memory(*w3wp*)\
\.NET CLR Memory(w3wp#*)\
\.NET CLR Memory(w3wp*)\
I've looked at the documentation here, and it seems like it claims to support wildcards, but not partial matches. I'm not sure what to make of that. Is there any way accomplish what I want? Hope I explained this well enough. Let me know if more details are needed.
Thanks!
There is a way to display the instance by appending Process Id to it. Since ProcessId do not change it helps determining the correct instance. This post describes the method - Perfmon: Identifying processes by PID instead of instance.
Relevant part from the link:
Making below registry change will display processes in the format of **ProcessName_PID** instead of **ProcessName#1**.
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance
On the Edit menu, click New, and then click DWORD Value.
Right-click New Value #1, click Rename, and then type ProcessNameFormat to name the new value.
Right-click ProcessNameFormat, and then click Modify.
In the Data value box, type one of the following values, and then click OK:
1: Disables PID data. This value is the default value.
2: Enables PID data.
Exit Registry Editor.
Warning: Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
Important: If you enable this feature, you may be unable to monitor process-specific information by using third-party utilities or custom-made programs, and this functionality may change at any time in the future without notice.
Hope it helps someone.
I came up with a custom batch script that find the application pool ID, PID, and associates it with the IIS worker process in question. From there, I can manually FIND and REPLACE a generic placeholder in my perfmon configuration file to start collecting for the specific site(s). I can supply some details if there is interest.
Open a TextEdit document with a few words in it. Notice that when you right click on a word, you can click "Look up (Word)" to get its definition or "Speech Start Speaking" to hear it read out aloud.
How can I build a local application to monitor globally whenever a user has requested a dictionary definition or the speech synthesizer?
Couple of ways I can think of are
injection and Hooking. If its cocoa application you can also try swizzling. I think with this approach its very easy to manage what you are trying to do. But it can be lot of work.
If you follow apple techniques so they must be sending notification that can be catch between applications. Try to find them and you are done.
Hy everybody,
I'm wondering if it's possible to add a new button via C++ or C# to windows 7 explorer "context strip"(don't know if this is correct name) - like on picture below.
My reason for this is because a lot of times I'm switching on&off "Show hidden files, folders and drives" functionality under Tools->Folder option->View. Therefore i want to simplify this process with a click of a button.
I was looking into ShellExecteEx function, but I am not sure I can do that. Can Anybody direct me in right direction?
thanks,
regards
I highly recommend using AutoIt for this task. Second URL comes complete with examples of how to insert buttons in various programs - however, be sure to read complete topic for misc. updates to the provided code.
See:
http://www.autoitscript.com/forum/index.php?showtopic=9517
Btw: I misread topic to begin with; gui 'context' related material in Windows is often taken to deal with right-click menus
Edit: limit on urls for new users on Stack Overflow mean I had to cut out some of less essential links - google away.
To answer part of the question, I think it is possible as for quite some time we've seen small programs to add a "New Folder" button to the explorer. I think those still works with Win 7.
Look at http://tools.tortoisesvn.net/StExBar for example
[Edit] Forgot to clarify that Source Code for StExBar is on Google Code
