// [STAThreadAttribute]

still m getting the exception

OK - well, that's how you set it. Do you set the thread model to something else, elsewhere in your code ? I don't even know if you can, but that attribute is what it's telling you to set. Have you googled the error message text ?

You need to write the code to save and reload your controls and their state, there's nothing built in that I know of

I think you can use seralization and deseralization then solve your issue.

i need to zip the files/folder. How can i use winzip32.exe in C# code to programatically zip the files or folder. If you could provide some sample code that would be great. Thanks

Process.Start will start winzip, so I guess if you can provide the files on the command line, that will do it for you. I thought zip support was built in now, I know for sure there are third party libraries you can use. WinZip is a commercial product, you need for your users to buy it if you use it for zipping.

I found the class System.IO.Compression.GZipStream which might serve the purpose. I have never used it though.
Have you come across this class??

I've not used it, but I had a feeling that such a class was in the newer versions of C#.

It was introduced in .NET 2, and people who've used it have noticed some issues with it.

My requirement is to zip the files if i use System.IO.Compression class the files are compressed. again for decompression i have to write a program. I want to use WinZip utility only.
I used the Process.Start as shown below
System.Diagnostics.Process.Start("C:\\Program Files\\WinZip\\winzip32.exe -min -a D:zippy.zip D:\\1.txt");
but i get an error at run time "The system cannot find the file specified"
If i specify only the exe name System.Diagnostics.Process.Start("C:\\Program Files\\WinZip\\winzip32.exe");
then winzip exe is opened. How do i specify the parameters. Please help

I thought the compression classes used the same algorithm as winzip ?

I tried to compress file using GZipStream but when i used WinZip32.exe to unzip the files it dint work. It gave an error message "Cannot open file. it does not appear to be a valid archive"
Does this mean that compressing class GZipStream does not use the same algorithm as Winzip?
If that is the case then i cannot use GZipStream to zip the files. Please let me know if you have any other suggestions. Thanks

The value gives the clue. int? is a shortcut for INullable<int>, which is to say, a wrapper class that wraps an int, or null, which allows you to store null for an int value. You can put the ? after any value type as in double? or Decimal?
