Does anyone know how to remove a Windows Service if the original program that installed the service refuses to uninstall it?
|
|
|
|
|
Try the following:
Try to stop the service manually before uninstalling.
If that does not work, set the start type to "manual" and reboot. The service should now be disabled. Try uninstalling.
If that does not work, remove the executable file from the hdd and run some "registry cleaner" which should(!) remove all invalid registry keys.
Cheers
Sid

In addition to the aforementioned, if a registry cleaner does not detect
and remove the service, you can manually remove it by deleting (very
carefully!) its registry key from:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<service name="">
Use extreme caution when deleting reg. keys from this location, as it
may harm your operating system.

hi the re i'm wondering if any one cud tell me of an alternative for using system.xml.xpath & system.xml.xsl in the .NET CF (using C#.NET) as some of u might know both name spaces are not supported in the CF?!!
I'm trying to use this in smart device application:
XslTransform xslt = new XslTransform();
xslt.Load(stylesheet);
XPathDocument xpathdocument = new
XPathDocument(filename);
XmlTextWriter writer = new XmlTextWriter("result.html", null);
writer.Formatting=Formatting.Indented;
xslt.Transform(xpathdocument,null,writer);
my end aim is to display the result.html on a webpage on the pocket pc emulator screen, or on an appication's display (not at web page)
any help is welcome...
regards

Assume you have a system with high need for security. Further assume that this system supports plugins. Now the plugins can be loaded in a different application domain with more restricted security settings (e.g. they are not allowed to use reflection, the newtork drives etc.). A good side effect is, that the assemblies containing the plugins can be unloaded (they are unloaded once the whole application domain gets destroyed).

hi every one,
I am new to .net environment.I started to write simple codes using .net in visual studio.net.I am having few doubts.
1) IF I create a project in visual studio .net then how many different files are created and what are they.
2) If i want to transfer the project from one system to another So that i can modify the project what files should I transfer.
3)I want to know in which file is the IL code generated and how to execute the IL code like in java we have .class file.
4) If I want to transfer just the IL code can I transfer it and just execute it on other machine if it has .net environment.
Kindly help me and try to make me learn about this
Thanking you in advance

1. Switch your Windows Explorer to detailed mode. It will explain what each ending means in the type column 
2. You can leave away the bin and obj subfolders. Everything else should be contained.
3. Its a bit different in .Net. Unlike java .Net creates executable files (ending with .exe), which can be directly executed on machines having the framework installed.
4. Just copy everything you find in your build directory. This is normally (in C#) [ProjectDir]\bin\Debug or [ProjectDir]\bin\Release depening on the build mode.

hi robert,
Thank you for that.But I am not still clear with some more thing.For the third one you told that in .net it creates the exe file so if i transfer this exe to other machine then do I need to create the project again to execute it or can I run the exe with some utility.
I also have another dobut do I need to use visual Studio .net IDE to develop any of the .net project or can I do it in regular note pad and compile it.IF so how?
My next question is in the real market what do they do do they buid the IL code sell it.
I wold be glad if U can answer to my questions.
Thanking in advance.

.NET Framework itself contains C# compiler (cs.exe). So basicaly yes you can use notepad... But I recommend you to use IDE Not necessary VS, there are other IDEs, even for free.

.NET runtime takes care of it. Only "utility" needed is .NET runtime.

There is a tool for generating native (machine) code from .NET assembliess. This way you however loose advantage of .NET framework - as a cross-platform. It's usual to sell .NET assemblies.. at least Smartdata does so.

Nothing. Just double-click the exe. If it doesn't work, what error message does it show? (I think there can be problem that application requires v1.1)
satishrg wrote:

I assume you use IIS.. than you must tell it about ASP.NET..
ASP.NET IIS Registration Tool (Aspnet_regiis.exe)[^]
Then you must create virtual directory for webapp (with inetmgr.exe) and set permissions... how to do it is usualy written in article.
You said you can't run some demos from CP.. which ones?

Hi,
first of all you really need the .Net framework version 1.1. Please check if you have it before any further tries. You should easily get it as its even available via windows update.
Then which link did you follow to download the exe? Its stated in the article that you need the Nortwind database. It is included in this zip. The other demo link wont function because the requred sample database is not included.
If it still doesnt function please include the error message in the next post.

I have a class that inherites from another class. I launch a WindowsForm within this class and I need to access a function of the base class within this WindowsForm. Any ideas how to do this?
This is what I use in basic:
class BaseClass{...}
...........
class MyClass : BaseClass
{
function open()
{
Form1 myForm = new Form1();
myForm.ShowDialog();
}
}
...........
class Form1
{
public Form1()
{
<< run BaseClass function here >>
}
}
|
|
|
|

Depends on the visibility of the method you want to invoke in the base class. If it is public than it could look like this:
class MyClass : BaseClass
{
function open()
{
Form1 myForm = new Form1();
myForm.ShowDialog(this);
}
}
...........
class Form1
{
public Form1(MyClass blubb)
{
blubb.SomeFunction();
}
}
If the method is protected than Form1 cannot call it directly. In this case MyClass will need a public wrapper method which delegates the call further to its base class.

I'd like to override function calls within an unmanaged application, redirecting them to my own, with the ability to callback the original function if applicable.
I can't find much help browsing boards and google, but I have found the odd (unmanaged) C++ library. These seem to launch the target executible while "injecting" a DLL into the process, which has memory access to change the machine instructions.
Any ideas, examples or advice would be welcome.

I have this library. What are you intending to do? You won't be able to inject a managed assembly into another app and have it work properly, but you could P/Invoke a "normal" dll into other apps from a managed application. It all depends on what the end result is going to be.

The base application has a string hashtable add function that accepts three pointers as parameters, which is usually called as part of a special interpretted script system, the parameters are: Hashtable pointer (the scripts are non-OO), Name character array pointer, Value character array pointer.
I'd like to "override" this function and use it to issue special commands to an external data access layer which the script language has no support for, while allowing it to have normal functionality. ie.
addItem( table , "SQL:InsertProduct" , "'Compaq Monitor 18\"', $30, 2" );
I have isolated the jump call instruction that needs overriding, presumably it's simply a matter now of somehow changing that with my own instruction.
I need to know:
1) How to "inject" a native DLL into the base process (I'll research this P/Invoke)
2) How to replace function call for another (Perhaps out of the scope of this message board, I just know it has to involve yucky naked ASM.. :/ )
3) How to pass applicable (ie. "SQL:*") calls into my .NET application, perhaps passing a .NET delegate in via a C# extern DLL call.
In time I could probably discover the neccassary articles myself, the least I need is a feasibility check, and a warning of potential pitfalls.
Thanks for any help. I fear I have a lot of reading to do..
