Understand what you are doing before you try this. This code forcefully closes the handle to the file. If another app has held the file open, it has probably done so for a reason, forcefully closing it has a strong chance of causing problems/errors in the app. If it's your app that holds the lock on the file, forcefully closing the handle will be likely leave you with invalid/null objects. You should just close the file properly.
[EDIT]
I haven't tried it, and I'm no ASP.NET expert, but I suspect you'll have problems getting this code to run anyway, because you won't have the permissions to use P/Invoke in the server environment.

I understand it and I'm not encouraging him to do so. I just gave him an example. He decides whether he wants to use it or not.

Sorry, I didn't mean for you to understand it. I've read a few of your articles, I've no doubt at all that you know what your doing  I just meant for Exelioindia to be careful with using that. Probably should have made that clearer.

Could please be more descriptive.
Anyways this works fine for me:
int i = this.dataGridView1.SelectedRows[1].Index
Until you realize this message has nothing to say, its too late to stop reading
|
|
|
|
|
checking how many rows are selected in the grid.
First column is check box column.
this code will help to learn something
int count =0;
foreach (DataGridViewRow row in dgrdviewBranch.Rows)
{
bool selectrow = Convert.ToBoolean(row.Cells[0].Value);
if (selectrow == true)
{
count += 1;
}
}

The command line prompt for running winzip. The below command zips "1.txt" file into "zippy.zip"
C:\Program Files\WinZip>winzip32.exe -min -a D:zippy.zip D:\\1.txt
I want to do this programatically using C# using Process.Start(). I have trouble specifing the parameters for winzip exe. If i give only the exe name as below winzip application opens
System.Diagnostics.Process.Start("C:\\Program Files\\WinZip\\winzip32.exe");
When i try giving the parameters(file name etc) as below it gives an error at run time "The system cannot find the file specified"
System.Diagnostics.Process.Start("C:\\Program Files\\WinZip\\winzip32.exe -min -a D:zippy.zip D:\\1.txt");
I'm not sure if there is any problem with double quotes "". How can i specifiy the paramters? Please help

You specify the parameters as an argument, and I suspect you need to put the full path in quotes because it has a space in it. So, you're writing a program that will only ever run on your personal PC, no-one else will ever use it ?

I have specified the path in quotes but still not working. Can you please provide code snippet?
My requirement is that the files should be zipped using Winzip only so that user can unzip it. If i use System.IO.Compression.GZipStream then i cannot unzip the files. Again i need to have a program for decompression.

|

I found the solution. I was using Process.Start with 1 paramters instead of using 2 parameters (2nd paramenter for argument). Thanks for all your help

OK, I thought that might be it, too. Either way, I still think you're doing it the wrong way

I'd take a look at doing this in process if I were you. There are several free third party assemblies which will help you here. ICSharpCode.ZipLib does the job just dandy.

i am using C#.net 1.1 while using clipboard m geeting this exception
System.Threading.ThreadStateException: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
at System.Windows.Forms.Clipboard.GetDataObject()
|
|
|
|
|
// [STAThreadAttribute]
[STAThread]
public static void Main()
put that attribute in your entry point.

i have made an entry [STAThread]
public static void Main()
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.
