It is not possible. You cannot open a newer version of solution using an old version fo Visual Studio.
The only way you can do is create a new solution under VS2003 and add each file *.cs, *.resx, ... to this solution.
That's why, you must write your code as clean as possible. That means you can use your code in VS2003 and VS2005. Without something specific from VS2005.

i save my application settings in a settings.xml file. The settings.xml is editable with any text editor and therefore i always have to consider the fact the settings could ha been mnaullly edited. Is there a way io could encode or something my settings.xml so that the user cant see the the actual content. Also, how can i check wether my file has been modified.

I think you can create a hash for your file and put it at the beginning.
Then the next time you want to load that file, you must first create
a hash from it and compare it with the hash in you XML file. If it is the
same, then your file is not editted. Otherwise, someone has edit your file.
Use MD5ServiceCryptoProvider.

Iam working on MDI application and I have some problem.
For the main form, IsMdiContainer is set to true as well as the MdiParent for child form, is set to 'this' (main form).
But problem starts here.
I put all the codes for each controls in each separete class so it's easy to manipulate.
In Tabs class, I have all the methods, properties I need for adding, removing, renaming etc. tabs.
I also have a method for adding new child forms.
In this method, MdiParent isn't set to 'this', but to frmMain.ActiveForm.
The thing is that everything works great unless I try to add new tab from the other Form.
App then breaks at line MdiParent = frmMain.ActiveForm with this error:
Form that was specified to be the MdiParent for this form is not an MdiContainer.<br />
Parameter name: value.
How can I workaround this problem, but still have this method for adding new child forms in Tabs class?
Iam out of ideas.
Sorry if my post is confusing.

Hi,
ActiveForm is a static property of the Form class that returns currently activated form for the application but not the acitve frmMain instance. So in some cases you try to bind child form to the non-MDI-parent form.
To have access to your frmMain form from all your classes you can add static property to it (as in the Singleton pattern):
class frmMain
{
private static frmMain current;
public static frmMain Current
{
get
{
return current;
}
}
public frmMain()
{
current = this;
}
}
Then you can use this property to construct your MDI-child forms:
childForm.MDIParent = frmMain.Current;

Thank you Andrew, very much. It works like a clock.
I've tried something similar, but mine wouldn't work  .
I've used other class for this, and it happened nothing, no error, no action, no anything .
And again, thanks.

i'm writing simple application that uses TCPListener and Client - i use BackgroundWorker to make listening in other thread. It set, when any error ocured function will use ReportProgress function and it will cause event and event will notice window etc ;]. My question is - i'm trying without debugging (just run exe) it work fine, with no problems - but WHY when i'm doing this same operation WITH debugging i get exception i can't access component in thread control weren't created in. I chceked - debugger show this line of code is called in BackgroundWorker thread - but how it work in "normal" mode?

i think the same problem was with ma project,,,
i think we cannot run two prosess in 1 thread..(ie listening and connecting)
this will cause Cross-Thread exception...
so just create the setup and run the exe file.

Would be nice if you would give detail as to what your problem is with backing up and restoring a database using C#.
I'd like to help but I am too lazy to Google it for you.

Google[^]  . Um take a look at the first result, an article on this website non-the-less.
As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

I get a get lastest in VSS for a Huge project
It has several projects that require virtual directories.
So I decided to use the Setup & Deployment package.
So I want this VirtualFolder to point to my working folder. ( This is a Web Service by the way)
But in the properties it has the property "VirtualFolder". DO I use this as my local path to the working directory?
Or is this not possible. Basically I just want to set up virtual folders to point to my working folders that alrady have project files in them.
Can you help?
Thanks,
Nick
1 line of code equals many bugs. So don't write any!!

Hey
I have a problem, I have a lot of files and each file contains a lot of strings with length of 4.
There might be double strings in each file.
I need a fast way to implement a check of how many different strings I have in all the files together.
I can't load all the strings into memory, there are many strings.
The number of different strings can arrive easily to 100 millions.

If you need a distinct count then you have to loop! You don't need to load the entire file into memory, you can use a stream to quickly scan the file.
100 million seems like a large estimate for the number of distinct 4 character strings. Are you really looking for an alphabet of 255 characters? (or worse if unicode)? If you really will have this many distinct records create a file of the number of distinct possible records * 4 bytes and store the count as an unsigned int in the file offset.

That's even a small estimate.
I will have 2 on the power of 32 records maximum. I don't know if it is a good idea to build such a big file.

There is a difference between distinct records and records. If you want to count distinct records you must have a way of storing the count. 2^32 is roughly 255^4 which makes me wonder why it is even string data (they would more accurately be binary at this point)

You are right, It's 4 character binary. I need an efficient way to count the number of distinct records,

Index the files then loop through to count. However, 4^255 is huge and you will not be able to store the results in ram so you will need a file structure just to store the results. Better if you could use small subsets at a time.
