Hvordan implementerer jeg SQL Server Compact Edition 4.0?

jeg har lavet løsningen.

SQL Server Compact Edition består af 7 dll'er:

• sqlceme40.dll Det udokumenterede, oprindelige, flade API-bibliotek (.net System.Data.SqlServerCe.dll assembly er en indpakning omkring denne dll)
• sqlceca40.dll En COM dll, der implementerer Engine , Replication , Error og et par andre COM-objekter
• sqlceoledb40.dll En COM dll, der implementerer en OLEdb-udbyder til SSCE (tillader brugen af ​​ADO)
• sqlcese40.dll ukendt
• sqlceqp40.dll ukendt
• sqlcecompact40.dll ukendt
• sqlceer40en.dll ukendt

Problemet med blot at prøve at sende disse dll'er er, at to af dem er COM genstande. COM-objekt-dll'er skal registreres , f.eks.:

>regsvr32 sqlceca40.dll
>regsvr32 sqlceoledb40.dll

Problemet er, at registrering af et COM-objekt kræver administrativ privilegier (brug af en global løsning til at løse et lokalt problem ). Det betyder, at dine brugere ville

• skal installere din ansøgning (som du ikke ønsker at gøre)
• kræver, at dine brugere har administrative tilladelser (hvilket du ikke ønsker)

Heldigvis, fra 2001 med Windows XP, løste Microsoft dette FÆLLES problem:Registrering- Gratis COM .

Først skal du erklære, at din ansøgning har en "afhængighed" på SQL Server Compact Edition 4.0. Det gør du ved at oprette et montagemanifest:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> 
    <assemblyIdentity 
        version="1.0.0.0"
        processorArchitecture="X86"
        name="client"
        type="win32"
    /> 

    <description>Hyperion Pro</description> 

    <!-- We have a dependancy on SQL Server CE 4.0 -->
    <dependency>
        <dependentAssembly>
            <assemblyIdentity
                type="win32"
                name="Microsoft.SQLSERVER.CE.4.0"
                version="4.0.0.0" processorArchitecture="x86"
            />
        </dependentAssembly>
    </dependency>

    <!-- We are high-dpi aware on Windows Vista -->
    <asmv3:application xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
        <asmv3:windowsSettings
            xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
            <dpiAware>true</dpiAware>
        </asmv3:windowsSettings>
    </asmv3:application>

    <!-- We were designed and tested on Windows 7 -->
    <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
        <application>
            <!--The ID below indicates application support for Windows 7 -->
            <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
            <!--The ID below indicates application support for Windows Vista -->
            <!--supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/-->
        </application>
    </compatibility>

    <!-- Disable file and registry virtualization -->
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedPrivileges>
                <requestedExecutionLevel level="asInvoker" uiAccess="false"/>
            </requestedPrivileges>
        </security>
    </trustInfo>
</assembly>

Du kan placere denne fil ved siden af din eksekverbare (som Hyperion.exe.manifest ), eller du kan indbygge det i din applikation som en RT_MANIFEST ressource.

Bemærk, at vi har en afhængighed af en assembly kaldet Microsoft.SQLSERVER.CE.4.0 . Vi opretter først denne samling ved at oprette en mappe kaldet:

Når du implementerer dit program, vil du placere alle 7 dll'er, der omfatter denne "samling" ind i denne Microsoft.SQLSERVER.CE.4.0 undermappe sammen med en speciel .manifest fil:

📁C:\

      ╰──📁AppData
         ╰──📁Local

               ├──📄Hyperion.exe.manifest
               ╰──📁Microsoft.SQLSERVER.CE.4.0

                  ├──📄sqlcese40.dll

                  ├──📄sqlcecompact40.dll
                  ├──📄sqlceer40en.dll
                  ╰──📄Microsoft.SQLSERVER.CE.4.0.manifest

Med andre ord indeholder applikationsmappen din applikation og Microsoft.SQLSERVER.CE.4.0 mappe:

 Directory of C:\Users\Ian\AppData\Local\Hyperion Pro

           1 Dir(s)  20,851,503,104 bytes free

Den næste del af din opgave er at definere Microsoft.SQLSERVER.CE.4.0.manifest fil. Registreringsfri COM tillader en manifestfil at erklære alle COM-objekter og deres clsid'er. Dette krævede meget reverse engineering. Men montagemanifestet for SQL Server Compact Edition 4.0 er:

Microsoft.SQLSERVER.CE.4.0.manifest :

Det sidste er, at vi på samme måde er afhængige af en samling kaldet Microsoft.SQLSERVER.CE.4.0 , SQL Server Compact Edition 4.0 har igen en afhængighed af en samling kaldet Microsoft.VC90.CRT . Heldigvis leveres din installation af SQLCE med en kopi af denne samling:
