This is true in terms of availability of the namespace, but the unzipping zip file classes are available starting 4.5 FW. See for yourself: ZipFile Class (System.IO.Compression)[^]

You are referring to a helper-class that simplifies the tasks. The GZipStream is available in 2.0, and you could zip/unzip in 2.0 without using third-party libraries. Example on MSDN[^].

I am not sure how this will help me to unpack a zip file into a folder. The example there only shows how to compress/decompress a single file with GZip compression. I am familiar with that mechanism and it would be overkill to reinvent a library from Deflate/GZip classes in .NET to create a unpacker for folders packet into a zip container file. The example works just fine on a single file, but not on a Zip archive.

Then use one of the existing libraries. Did you not state you did not want a dependency on things like SharpZipLib and DotNetZip?

Yes, i did and thats why i was prefering the late binding option to the shell zip functionality build into windows. As said, the entire thing should be running from a single exe file with no extra libs attached. the zip com extension is available from XP up to 10. using the GZip/Deflate classes in that namespace supporting .NET 2.0 would require to implement a full unzipper for zip containers in zip format like implemented in the helper classes available starting 4.5 FW. that would be a total overkill.

Hi Richard,
thanks for the answer. Yes, i have seen that article before, but this uses early binding with a com wrapper. Thats the easy way, but i am looking for late binding at runtime with no additionall assembly file, like this project uses.

I have a MEF plugin that runs test for a medical instrument. The instrument starts the test service, and that service loads the MEF plugin and calls it's Execute method. This all runs in another thread.
The MEF plugin gets its settings from a Config file. Changes are made to the Config file using an editor designed for it. This editor is a stand alone EXE not connected to the instrument in any way.
The configuration can be set to run the tests for [n] times. This gives techs time to look at the instrument while its running.
1) Instrument starts the test process.
2) Test process loads the MEF plugin.
3) MEF plugin reads config file.
4) Tests inside the plugin execute using settings from config file.
5) At end of test, start next iteration until [n] is reached. Goto step 4.
What I'm wondering is this... Is it possible for an external EXE to somehow get data from the MEF plugin in real time? And, it also could commands be sent into the plugin, such as stop, pause, etc?
Thanks

You could easily use self-hosted WCF to do this. Set it up to publish messages via named pipes and it'll run no problem.

I don't like the bloat of WCF, but you can do secure named pipes pretty trivially without it.

I've never used PredicateBuilder before. If anyone has used it, I could use some help
List<PurchasingEntity> results = null;
IQueryable<PurchasingEntity> query = (from c in db.Companies
join p in db.Projects on c.Id equals p.CompanyId
join j in db.Jobs on p.Id equals j.ProjectId
select new PurchasingEntity
{
CompanyId = c.Id,
ProjectId = p.Id,
JobId = j.Id,
Phase = j.Phase,
Quantity = j.Quantity.HasValue ? j.Quantity.Value : 0,
StartDate = j.StartDate.HasValue ? j.StartDate : null
});
var predicate = PredicateBuilder.True<Purchasing>();
if (companyId > 0)
{
predicate = predicate.And(i => i.CompanyId == companyId);
}
if (projectId > 0)
{
predicate = predicate.And(i => i.ProjectId == projectId);
}
if (startDate != null)
{
predicate = predicate.And(i => i.StartDate >= startDate);
}
if (endDate != null)
{
predicate = predicate.And(i => i.StartDate <= endDate);
}
results = query.Where(predicate);
return results.ToList();
The compilation error is
cannot convert from 'System.Linq.Expressions.Expression<System.Func<Jayhawk.DAL.DataContext.Purchasing, bool>>' to 'System.Linq.Expressions.Expression<System.Func<Jayhawk.Entities.PurchasingEntity, int, bool>>'
Not quitre sure what's wrong here? Can anyone help?

I must have stared at that for an hour. Just didn't see it
var predicate = PredicateBuilder.True<PurchasingEntity>();
.
.
.
results = query.Where(predicate).ToList();
This works now

It will cause an error because you are assigning IQueryable to List.
You can try this:
results = query.Where(predicate).ToList();
return results
I didn't used PredicateBuilder but i used System.Linq.Dynamic to create dynamic filtering or order by.

No, I'm sorry - but we can't.
This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
So tell us what the error message is, when it occurs, and show us the relevant code fragments that generate the problem. Then tell us what you have done to fix the problem and what effects that had. the better the information you give us, the better the solution we can give you.
Help us to help you!

When I run my C# windows form application that contains Crystal Report. It's asking me to enter the credential for the MySQL db every time. Even though I entered the correct user name and password. it is saying my user name or password is wrong. I have checked the credential many times and entered password is correct.
Code :
private void cmdPrintReport_Click(object sender, EventArgs e)
{
CrystalReport_Quotation1.SetDatabaseLogon("DB_USER_AFDR", "1237894560");
crvQuotation.ReportSource = CrystalReport_Quotation1;
