P.S. I never did find a .sln file!
The snippet you posted is from the .sln file. (Do you, by chance, have "Hide file extensions for known file types" selected in your folder options? I have never understood why this is the default, but this is usually one of the first things I change when I sit down at a new machine.)
The alpha-numeric string starting with "FAE04EC0" is a GUID (Globally Unique Identifier) representing a C# project file (.csproj). The second GUID (the one that starts with "CA22A93D", in your case) respresents the actual project (DACISV2).
I made the assumption (a bad practice, I know) that you were working with WinForms applications, but I see from what you posted that you're actually working with web apps. The location of the code files can vary depending on how you added them to the solution, but by default they'll be in C:\Inetpub\wwwroot\{ProjectName}. This will be different if you didn't go with the defaults when setting up IIS on your machine. You'd need to make a copy of those folders as well.
To restore the "backup", either replace the newer version with the saved version and go about your business or alter the saved solution file to point to the backups you made of the projects. You'd just change the path in the solution file to point to the new location. e.g., "http://localhost/Copy of DACISV2/DACISV2.csproj"
If you don't want to have to deal with all this stuff, there is a good source control tool called SourceGear Vault[^] that is free for single users. Using a source control system adds a certain amount of complexity itself, but it can also add a lot of flexibility when restoring a previous version.

Hi all !
I have a RichTextBox control containing red-colored text "Hello world." and
I need to get (for example but not strongly !) the following html-page:
<html>
<body style="color:red">
Hello world.
</body>
</html>
Does FCL contain any classes and methods to solve my problem ?
Many thanks !

hi
i am working on a full screen app, and was wondering if there is any way of hiding the taskbar.

Yes, in the form that you want to fill the screen, handle the Load event inserting the following code:
this.FormBorderStyle = FormBorderStyle.None;
this.Location = new Point(0, 0);
this.Size = new Size(Screen.PrimaryScreen.Bounds.Width,
Screen.PrimaryScreen.Bounds.Height);
You may want to set the form's TopMost property to true as well.
Hope that helps. 
Happy Programming and may God bless!

Hi
My company is hiring and I'm stuck with writing a meaninful set of questions so interviewers can ask the prospects about .NET and ASP.NET
This are Senior level Developers positions that will be in charge if developing from specs or sometimes without specs web-based and smart client applications.
On top of .NET they require amomg other things
- N-tier architecture
- component development
- UML and RUP
- Data modellling
- ORACLE
- PL/SQL
Any how , can someone point me to standards question that can ask to determine the level of knowledge on ASP.NET and .net in general.

Hi,
Well a good start would be with the garbage collection. Ask them what is garbage collection, and the mechanics of it. Make sure u read about 1'st and 2nd generation garbage collection. this will help you understand and also compose some questions.
Also you can ask them about the .NET tools, such as ILASM-ILAssembler, ILDASM-ILDisassembler, and of course IL. IL is the bytecode of the framework. Any experienced developer would certainly know a bit about IL, Intermediate Language.
And for asp.net I would ask about security. Such as Forms.Authentication namespace, simply for the reason that if any developer has worked with asp.net they would definatly work with Asp.NET security namespaces. Also I would definatly get into the DataGrid control since its advanced and very powerful.
Maybe Class Libraries can fit in there too, and component development.

Why? There really isn't much to know other than to use Dispose if an object uses IDisposable, and implement IDisposable yourself if your class has member variables that use the IDisposable interface themselves.

Huh! What does that really get you? While the information could be useful there are a number of really great .NET developers I know that don't use IL or the ILAssembler/Disassembler.

Why stop there? What about security in Win Forms Applications? What about security when dealing with the database? Security is a huge topic and covers many areas.

Personally, I find that data grids are extremely poor. They are good for mocking up a quick prototype but they are cumbersome and difficult to change if you want to do anything more than simple grids.

Are you talking about the .NET BCL (Base Class Library)? And you say "Maybe"!

I would suggest the best policy would be to put someone technical on the interview panel rather than have someone non-technical ask the questions. A non-technical person will either only accept the answer as written down for them (the person may know the answer, just not express it in the same way) or could be bambozzled into accepting a false explanation.
I would say that the .NET Framework is so big that few people will know all of it in depth. Think about the projects you will need this programmer to work on and ask question in those area. If you find a test to ask prospective .NET developers make sure it asks questions that are relevant to the work you do. For example, you mention Oracle, so asking questions about classes in the System.Data.SqlClient namespace will be a bit pointless, but asking about System.Data.Oracle will be relevant.
You might try looking in books designed for the MCAD and MSCD courses as they often have sample exam question at the end of each chapter or at the back of the book.
I would say that the most important qualities of a good developer are willingness/eagerness to learn (information becomes old very quickly in IT), be a good logical thinker (this allows them to think through problems - especially ones they may not have encountered before).
Anyway, I hope this helps.

Give them a notebook with VS.NET 2003 and access to the Internet, and ask them to write both a web application and a winforms application to query the pubs database for authors, and then show the books by the selected author. Give them an hour.
They may not complete, but you should be able to evaluate their knowledge of how to do multi-tiered apps, and how well they know some aspects of .NET. A faker will not be able to do anything in an hour, and a guru will impress the hell out of you.

Hi,
I have a multiple resultset returned by the stored procedure (4 select statements returning different values).
When I call SqlCommand's ExecuteReader on the following piece of code:
cn = new System.Data.SqlClient.SqlConnection(ConnectionString);<br />
<br />
cn.Open();<br />
<br />
SqlCommand cmd = new SqlCommand();<br />
cmd.Connection = cn;<br />
cmd.CommandText = "spResSupervisorSwitchboard";<br />
cmd.CommandType = CommandType.StoredProcedure;<br />
<br />
SqlDataReader rdr = cmd.ExecuteReader();<br />
<br />
while(rdr.Read()) <br />
{<br />
lblWaitingFirstEntry.Text = rdr[0].ToString();
}<br />
<br />
rdr.NextResult();
The connection is opened fine, the stored procedure name is correct, stored procedure returns values when executed in SQL Query Analyzer... but it doesn't work in my code. 
Cheers

from what i see, code is not wrapped in a try catch block. you also don't close the connection, and rdr.NextResult is not needed since rdr.Read() enumerates through set in a DataReader. plus ur opening the connection before ur setting cmd fields.
try this
cn = new System.Data.SqlClient.SqlConnection(ConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.Connection = cn;
cmd.CommandText = "spResSupervisorSwitchboard";
cmd.CommandType = CommandType.StoredProcedure;
try{
SqlDataReader rdr = cmd.ExecuteReader();
while(rdr.Read())
{
lblWaitingFirstEntry.Text = rdr[0].ToString();
}
}catch(SqlException ex)
{
lblWaitingFirstEntry.Text = ex.ToString();
}
finally
{
con.close();
}

If your working in Windows 2000 or XP , then there might be a possibility that your account lacks the access rights to do so. Especially when your are creating an ASP.NET project then the error appears as can't be created. Since your error message isn't clear so this might be a possibility (if your account is other than the administrator one) . Or your VS.NET is not installed correctly... so check the possibilities.

Hello all,
Does anyone know how to get the localized name of default directories in the .NET framework? For instance, I know the German "Program Files" folder is "Programme" , but how can I find out what it is at run time?
I looked through the System.IO.Path class (which looked promising), but never found a solution.
Thanks all,
John Guin

I think the "native" Property Grid control has a PropertyChanged event which fires when the property was changed and the user moved the focus from the changed property. This is not quit enough for me.
Does anyone know if I can somehow wire to the "editing" event. That is an event which fires while the property is edited?

Hi guys,
I'm reading an XLS spreadsheet into my application using an OleDbDataAdapter into a DataSet. Everything works fine, except that cells which contain more than 256 characters of text are being truncated to 255 characters.
The odd thing is, if I make the first line of the XLS longer than any other subsequent lines - everything is read in correctly.
It's almost as if the column string lengths are being set based on the first couple of lines read in.
I'm not sure where to go from here, on how to fix this... anyone?
Thanks
Dave

The Excel Providers default behavior is to determine the column datatypes by scanning the first 8 rows. This is can be modified somewhat by setting the MAXSCANROWS property in your connection string (in the EXTENDED PROPERTIES part). This accepts a range of values 0-16. 0 means scan the whole table. If you scan the whole table column data types will be based on a 'majority rules basis, which can cause columns with mixed text and numeric data to start failing one or the other. Another alternative might be to set IMEX=1 in the connection string (also Extended prperties). this sets 'import export mode" so all columns are interpreted as text regardless of content. Not sure how this agfects the string length determination, but it might be the best bet for your situation.

My client exe refering a assembly dll version 1.o which is in GAC.
As i found some bug in dll version 1.0, i corrected it and make it version
2.0.Now i want my client exe to refer 2.0 without compiling the client exe
again.How to do this.

If you want to redirect all applications on a machine which use this assembly, you can use Publisher Policy[^] to redirect all uses of this assembly to the new version.
Things to be aware of:
The framework looks for a publisher policy file with the major and minor version of the assembly reference. If you patch this assembly again, calling it v3.0, and you want clients which need v1.0 and v2.0 to use v3.0, you'll need to ship policy.1.0.assemblyname.dll and policy.2.0.assemblyname.dll. I'd recommend keeping the same major and minor version numbers for patches, incrementing only the last two parts of the version number (build and revision). Only change the major and minor version number for breaking changes in the interface.
You must use the same strong-name key to sign policy assemblies as the original assembly.
You must set the version number on the policy assemblies. The GAC install process will silently fail to overwrite a policy assembly with the same or lower version number.
It isn't fully clear in Microsoft's documentation - you CANNOT embed the policy XML file in the assembly DLL file. The assembly must link to the policy file.
The publisher policy system is most useful for security patches.
If you want to redirect a single application, you can use bindingRedirect[^] elements in the application's configuration file.
You should generally default to not putting your own assemblies in the GAC. See this blog post[^] for reasons.
Stability. What an interesting concept. -- Chris Maunder

Not certain what is required when developing a packaging and deployment application for a C# windows program with several forms. First, when the application is built using the Build menu command, does it incorporate the forms into the executable itself, or do the forms need to be included individually into the application. If they are required to be individually included into the application, then is there perhaps some way that these files could ALL be converted to individual .dll files or even incorporated into a single .dll files, or something? It would seem to me that if each file were required to be included into the application individually, that they would be too vulnerable -- any suggestions?
Also, when the path to files are written in the code for your application, and the files are expected to be stored in "C:/windows/" directory, for example, the package and deployment folder for Windows could store the files in WINNT or in Windows based upon which operating system is loaded onto the client computer. Since the programmer does not know what operating system the user is utilizing, how would the programmer write the path information to where the files are expected to be installed by the installer? That is, is there some environmental variables code that would work with the package and deployment program in which the deployment application makes the determination where to store the files during installation, and the code path to the files would agree with that path decision? Is there some code like Application.windir() or something?
Third question. If an application required the installation of other applications, or even the .NET framework itself, does the package and deployment application provide a transparent way of installing these applications first without the end user realizing that they are being installed? We have all seen the applications that have several installation modules included, and they are considerably bothersome to the end user. I would like to install the other applications and even the .NET framework transparently without the end user knowing that it is occurring. That is, if the .NET framework is installed already, then ignore, else install. If the third party application is installed already, do likewise. Any ideas?
Would really appreciate the input on these questions, as I do believe that others would like to hear the answer as well. Thanks.
