Hi all...
I'm in the process of writting a little app to control my NT servive as it runs on our server farm. There are going to be lots of machines running and having to manually configure each one will be a pain in the arse, thus my question...
Given that I already have a ServiceController object and looking at Service X on machine Y, how do I get back/alter the startup mode of that service. I have found the ServiceInstaller object but am unable to get it to populate with the info for the service I am looking at in the ServiceController object...
Any ideas?
Thanks
Pete

Hi
I want to develope an client application to update/retrieve data from a remote database namely SQL on some maching over the Internet. For example, application to connect to TheCodeProject database to retrieve the appropriate data, format it then output it. In the essence, it just acts like off-line forum reader , without having open the browser and offer some extra functionality like saving, attaching files, etc.... However i m still in the dark of how about to do it. I would like to ask some questions related to the matter:
1) Is C# the most appropriate language to do this?
2) What sort of configuration does the MySQL server needs to apply for my application to make a connection?
3) I want to make the interface of the application Outlook liked, how would i do so?
Thank alot for reading this and looking forward to receive your enlightment!
Best Regard

Sounds like a job for a web-service that sits on your server and serves requests for data. Having a direct connection to your database over the internet is a security nightmare.
C# will allow you to write both the client and server components.

For MySQL to work with C# you will need ODBC.NET.
You will also need MyODBC.
Read the help pages for these and you should be all set.

I have recently begun to use NUnit to test a C# project that I am doing for work. However I have run into a snag. Because most of my code is in the executable and not in a DLL, it is difficult to use NUnit to test it. VS.NET won't let me add a reference to it. I find this a little odd because you can just copy the executable to a DLL and then add a reference. But anyways.
NUnit recommends that you just add all of the test code into your executeable project. I disagree with this heavily as I don't want to be shipping out an executable that consist of about 1/4 test code. So here are the solutions I've come up with.
1) I could just wrap an #if DEBUG around the entire class for all of my test classes and put them in their own namespace. I am against this because I feel it is a nasty solution. To much like a lot of the C code that i have seen.
2) Put all of my project code into a DLL. Then have an executable project consisting of one class that calls the main method of the DLL. Then when I wanted to release I could just change the Release to make it an executable instead of a DLL.
Has anyone else come upon this siutaiton before and found a better solution? If nto which of these do you think is preferable

Hi All,
Can someone tell me like in our tradional model we have MTS as application server, wht is subsitute of MTS in .net platfrom... where I can deploy my components written in c# and forget abt the resource pooling and memory mgmt.
|

|
|

This is quite a common point of confusion.
Firstly, COM+ (MTS 2) is still alive and well inside the .NET world.
You can add a .NET assembly into COM+, but you need to be aware that you will also be adding the overhead of COM interop.
Remember that you have a far lesser instantiation overhead in .NET as you had in COM.
Mem. management is handled for you in .NET.
Can you provide some more info on the type of application this is for?
Cheers,
Simon

Spotted on GotDotNet.com (somethin i was in fact looking for a few weeks ago):
GotDotNet Workspaces Beta Coming Soon
GotDotNet Workspaces is an online collaborative development environment where .NET developers can create, host and manage projects throughout the project lifecycle. Want more information? Check out the new GotDotNet Workspaces whitepaper and don't forget to sign up to receive e-mail announcements about the GotDotNet Workspaces Beta Program!
I hope being a big supporter of CodeProject that we could see somethin similar soon . I find that at sourceforge and freshmeat, that you dont seem to reach your intended audience. While if it was hosted on a .Net or even better a C# site, you could make source available as well as get others to directly view your source or become part of your development team.
Cheers

Hi all,
How would one change certain text's formatting inside a RichTextBox programmatically?
I have gotten quite far with this for the following few exceptions:
- Everything is OK until 2 styles overlap (eg. bold and underline). Thus, I need to tackle every char on its own, but this is a no-no as it is too slow ( in my attempted implementation I had to do a single pass for every style  )
- Every other "road" I take seems to run into even more preformance issues even before results can be seen.
From what I can see, you have to ways to do this:
1. Format text on the fly (as it gets appended) char by char.
-or-
2. Append all text, then apply formatting on a char by char basis.
Both of these have preformance issues. Is there a way of delaying the invalidation of a RichTextBox and calling it only once all formatting has been applied? Perhaps someone can help me with this. If you need more info, please ask, I'm not so sure if the question is as clear as it should be.
Thanking all in advance.
Cheers

There is a 3rd and quicker way that seems to work better by parsing the string on a char by char basis and "recording" the formatting then apply it in string "chunks" each with it own formatting, but its still very slow on complicated formatting
Preventing the RichTextBox from invalidating could solve this, but I m yet to succeed. Its allmost like i need a RichTextBox backbuffer, to do formatting and then I could paste to visible RichTextBox. Maybe, maybe not

What are the differences between...
- string and String?
- casting a value using (string) and using ToString()?
Please help, I'm kinda confused. Thanks.
What? Were you expecting something witty or funny here?

nothing Same as int = Int32, short = Int16 , bool = Boolean, etc. MSDN defines them as aliases.
overbored wrote:

The ToString() method allow programmers to have a friendly text definition of an object. EG font.ToString() will return all the font's parameters, name, etc. Purely informational, where a (string) object wont be allowed unless the object is a string or a string cast has been implemented (not sure on how you would do this).
Hope this helps

You can do this with the implicit and explicit operators. Here is a small bit of code that will allow a class to be implicitly cast to a string.
<br />
public static implicit operator string(MyClass c) {<br />
return c.ToString();<br />
}<br />
This will allow for the implicit conversion of MyClass to a string. If you want to force people to explicitly cast to a String then change the keyword to explicit instead of implicit

String mostly used in ASP.NET I think.And convert to string there.

I am making a download class, kinda ambitious, considering I know little, but, at the moment, it supports paused/resume downloads, and saving the state of the downloads, so the program ccan be shut down, and the downloads will carry on when iots started up again. anyway, i am trying to add support for multiple downlioad locations, and i want to be able to generate a checksum, or something, for the remote file, and the local file, so that i can verify if the file was downloaded successfully, but i do not know how, any help, or pointers in the right direction?

Thats not really possible unless you own the internet 
I assume you want somethin similar to eDonkey's file hashing to prevent corrupted downloads. Unless you can control the other side, you cant get a checksum.
I also presume you want somethin similar to GetRight's Segmented downloading. Most programs doing this, creates a blank file to the size (from the returned HTTP header) of the downloaded file, then writes to the file byte by byte.
You can easily run a "scan" thru the file to see what is still needed. Also by changing the header sent u can resume most files if the server supports partial content (see below).
Nnamdi Onyeyiri wrote:

In your your Download class change the "URL" property to URL[]. Or if you dont have somethin like that, you might want to create it to keep track of other variables like speed, pingtime and availability. Also note that you will need to make sure each download location has exactly the "same" file by comparing the sizes. Also , you need to make sure that the remote file's date hasnt changed (incase file size is the same) when resuming the download, although some servers might create the file on the fly to prevent leeching 
Hope this all helps
Example of header sent for partial content:

Try referencing them all to the same filestream, you will be writing a byte buffer (say 4kb) at any one time, using a lock to prevent (or rather queue) the other threads from writing to the stream at the same time.
READ MSDN

the byte buffer will be written to the file sequencially , you will just need to keep track of the start offset where it should be written in the file for each thread
