I have a empty project (compact framework 3.5) for pda. I add a imagelist and i add a image in the list. When i deploy the project at a CE7 device (Motorola MC32N0) i get a PlatformNotSupportedException at the line
this.imageList1.Images.Add(((System.Drawing.Image)(resources.GetObject("resource"))));
The stacktrace is:

I only get this exception in CE7. Any ideas?
I think MC32xx has only a "core" CE7. I had a similar problem. Have you got installed Compact Framework 3.5 properly. What does the windows\wceload.exe show you? Maybe you have to install this seperately.

I work on a Api project in .NET core 2.2 with NHibernate (5.2.5)
Table A has nullable foreign key from table B
I need to create a criteria to filter Table A, using a nullable foreign key (which is not null) that points to Table B, where the Status in Table B is 3
This is something what I have tried:
var criteria = _session.CreateCriteria<AgencyAgreement>();criteria.Add(Restrictions.Eq("BookingCartItem.Status", (int)BookingCartStatus.Cancelled));
also with and operator
criteria.Add(Restrictions.And(Restrictions.IsNotNull("BookingCartItem"), Restrictions.Eq("BookingCartItem.Status", (int)BookingCartStatus.Cancelled)));
but this is what I get as Error

I'm using Nhibernate 4 and FluentNhibernate 2.0.3 with db Microsoft Access 2000. I can't save the entry on the DB because i'm getting an error when I go to insert the Note field sending a request HTTP POST for example:
{
"Note": "bla bla bla"
}
NOTE: In the database table, the column "Note" is setted as "LONG TEXT" (Not Required)
Could It be a problem of conversion of data Types?

I have the following code that works in SQL:
"(CASE WHEN isnumeric(Installation) > 0 THEN cast(Installation as bigint) ELSE null END) "
I am trying to convert it to work in SQLite, but having trouble since I have very little experience in SQLite. Basically I want to cast/convert my stringcolumn (Installation) to a bigint, but need the validation to make sure it only contains numeric characters.
I have tried the following 3 variations, but not having luck. Just getting errors saying could not execute query
("(CASE WHEN Installation GLOB '*[^0-9]*' THEN cast(Installation as bigint) ELSE null END)");
("(SELECT Installation from ShortCycleWorkOrderCompletions WHERE Installation = REGEXP '*[^0-9]*'");
("(CASE WHEN REGEXP(Installation, '*[^0-9]*') THEN cast(Installation as bigint) ELSE null END");
Don't need all 3 to work, just one, and these were what I have tried.

Almost the same answer :
CASE
WHEN
(NOT TRIM(Installation) GLOB '*[^0-9]*') AND TRIM(Installation) like '_%'
THEN CAST(TRIM(Installation) AS BIGINT)
END AS intInstallation
Explanation :
[^0-9] = every character that's not a number
With the NOT you get all the installation who doesn't have a character that's not a number
'_%' wildcard : _ any character once and % 0 or more of any character.
Since your edit, I look at the query :
THEN CAST(TRIM(shortcycle0_.Installation) AS shortcycle0_.BIGINT)
Replace it with :
THEN CAST(TRIM(shortcycle0_.Installation) AS BIGINT)
Use the below condition, which checks the existence of non numerical characters and the length of the trimmed value of Installation:
CASE
WHEN
(NOT TRIM(Installation) GLOB '*[^0-9]*') AND (LENGTH(TRIM(Installation)) > 0)
THEN CAST(TRIM(Installation) AS BIGINT)
END
Note that the data type BIGINT in SQLite, is actually INTEGER (1-8 bytes signed integer).
We have windows appfabric cache server on win2k8 server and have installed “Windows Server 2003 Distributed Cache Client” on win2k3 web server from this link .
We are getting below exception while getting the cache object from cache factory.Can anybody help us to understand the cause of exception and its solution? Please note that below exception is not thrown while adding or getting cache data.
Our main purpose is to get & put cache data to windows appfabric server(win2k8) from win2k3 webserver client.

I've got a painfully simple table that is giving me a "Specified cast is not valid" error when I try to delete one or more rows. The table has two columns, an "id" as the primary key (INT), and a "name" (VARCHAR(20)), which maps to a String in the LINQ to SQL dbml file. Both of these statements produce the error:
dc.DeleteOnSubmit(dc.MyTables.Where(Function(x) x.id = 1).SingleOrDefault)
dc.DeleteAllOnSubmit(dc.MyTables)
I iterated through "MyTable" just to make sure there was no weird data, and there are only two rows:
id = 1, name = "first"
id = 2, name = "second"
The exception is happening on SubmitChanges. Here is the stack trace:

Removing the association added to the DBML file allows rows to be deleted. Why would the association be causing the error? The associated columns are both VARCHAR(20) in the database and resolve to Strings in the DBML file.
What could possibly be causing a casting error?
Okay, upon seeing the update, the issue is the association between your two tables. This is a known bug in .NET 3.5 SP1 and will be fixed in .NET 4.0. Try your code on a .NET 4.0 Beta if you can.
We had a similar problem, caused by using non-integer keys. Details and hotfix number are here: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=351358
