问题 Is there any simple and compatible GDI or .NET accessible subsystem of Windows that will give glyph position characters. The task here is the combining symbols such as those in Arabic which sometimes have chains of multiple combining symbols stacking on top of each others such as Arabic Fatha + Arabic Letter Superscript Alef + Arabic Maddah Above. The trouble is that though the X positions can be determined precisely with GDI GetCharacterPlacement, the Y position calculations which are

问题 I did my best search to convert PARTION BY command from TSQL to LINQ command. But apparently there is no way to convert it. This is my code to which I am going to convert: WITH MyRowSet AS ( SELECT OrderDate ,SalesOrderNumber ,AccountNumber ,CustomerID ,ROW_NUMBER() OVER (PARTITION BY CustomerID ORDER BY CustomerID, OrderDate DESC) AS RowNum FROM [Sales].[SalesOrderHeader] ) SELECT * FROM MyRowSet WHERE RowNum = 1 If exist any solution I would be greatful to know. 回答1: linq2db has this

问题 I could not find anything on this particular problem, so here it goes! I am interested in changing the position of the mouse cursor programmatically. Cursor.Position = new Point(x, y); works as expected using a single monitor. However, when I plug in a second one and choose to extend the desktop, changing the cursor's coordinates only works relative to the main screen. So, does anyone know how to tell the cursor that I want to move to a different screen? 回答1: Get the width and height of your

问题 I have this two errors: 'System.Array' does not contain a definition for 'Aggregate' and no extension method 'Aggregate' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

问题 I'm trying to connect to a IBM MQ using .net core ( "IBMMQDotnetClient" Version="9.2.0.1" ) with a certificate inside a linux container ( mcr.microsoft.com/dotnet/core/runtime:3.1 ).

问题 Unlike .NET Standard 1, .NET Standard 2 introduces a single netstandard.dll reference assembly. However, when compiling (with .NET Core SDK 2.2.203) with dotnet build we can see that it adds references to many assemblies (113), all under netstandard.library/2.0.3/build/netstandard2.0/ref/*.dll . One of these references is netstandard.dll . $ grep TargetFramework *.csproj <TargetFramework>netstandard2.0</TargetFramework> $ dotnet build --verbosity normal | grep -o netstandard.library/2.0.3

问题 I get why .Net Framework could cause issues in .Net Core, IE because an API specific to the Windows platform doesn't exist. But why wouldn't you be able to directly reference .Net Core as a library in .Net Framework? If .Net Core runs on windows, what is preventing a .Net Framework app from using .Net Core as if it were a library? I'm aware that you can port the .Net Core library to a .Net Standard Library, but my question is why .Net Framework can't just reference anything written in .Net
