VS2010 Crystal Reports dll older version vs newer version

VS2010 Crystal Reports dll older version vs newer version The problem  - I have Visual Studio 2010 SP1 installed on Windows 10 32 bit, I had CR4VS 13.0.2 working perfectly on both developer machine and client machine with no problems. - I downloaded CR4VS sp16 (exe) - I uninstalled CR4VS 13.0.2 completely - I installed CR4VS sp16 (exe) successfully - Now, each time I open my Visual Basic 2010 Project I notice that the old CrystalDecision dll still has the same version 13.0.2000.0, although in my C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet .... I have the new version of dll.

After searching and searching and searching for a solution and also many un-installations and installations trials, I've found the following :

Solution :
Visual Studio 2010 loads its assemblies dll from C:\Windows.old\Windows\assembly\GAC_MSIL not from C:\WINDOWS\Microsoft.NET\assembly\GAC_MSIL

VS 2015 Crystal Report 13 Update 16

Crystal Reports in Visual Studio 2015, 2017, 2019
- Problem:  After installing Crystal reports for Visual Studio 2015 service pack16 (CRforVS_13_0_16.exe), I opened Visual Studio and I could not find Crystal reports or Reports Section in Tool Box items.
According to information from SAPTo integrate SAP Crystal Reports - developer version for Microsoft Visual Studio, you must run installer executable CRforVS_13_0_24.exe file. Running the MSI will not fully integrate Crystal Reports into VS.MSI files by definition are for runtime distribution only.
By default Windows 10 does not install the 3.5 framework, CR for VS still needs it. Select it by "Turn Windows feature on or off" and choose both options. Solution : Reports section in VS 2015 Tool Box Open Control Panel > Programs > Programs and Features, and select the entry for your version of Microsoft Visual Studio 2015. In our case, it was Microsoft Visual Studio Enterprise 2015. Click the "Change" button on th…

.Net framework 4.5.2 for Visual Studio 2010

.Net framework 4.5.2 for Visual Studio 2010 If you have installed Visual Studio 2010 on Windows 7, 8, 10 recently, you will notice that you have all .Net Framework versions available, and you will notice also that you Windows updates .net framework versions to a higher versions (i.e. If you have .net framework 4, windows will update this to 4.5) but you won't find .net framework v4.5 in your Visual Studio 2010, why ?!
Because targeting .net framework 4.5 via Visual Studio 2010 Each version of VS prior to Visual Studio 2010 is tied to a certain .NET framework. (VS2008 is .NET 3.5, VS2005 is .NET 2.0, VS2003 is .NET1.1) VS2010 and beyond allow for targeting of prior framework versions but cannot be used for future releases. You must use Visual Studio 2012 in order to utilize .NET 4.5.

VB 2010 MS Access Compact and Repair Database

MS Access 2003/2007/2010 Compact and Repair
Neither ActiveX Data Objects (ADO) nor ADO .NET provide the means to compact or repair Microsoft Access databases. However, you can accomplish this task by using the Microsoft Jet OLE DB Provider and Replication Objects (JRO) that was introduced with Microsoft Data Access Components (MDAC) version 2.1. ADO .NET allows the use of COM-based object libraries through the Interop layer.
This article demonstrates how to compact an Access database by using Visual Basic .NET.
RequirementsMicrosoft Visual Basic .NETMicrosoft Jet and Replication Objects 2.1, 2.5, or 2.6 Library - For *.mdb file (200-2003)Microsoft.Office.interop.access.dao Assembly - For *.accdb file (2007)
Steps to build exampleOpen a new Visual Basic .NET console application.In the Solution Explorer window, right-click the References node and select Add Reference. If you are targeting ms access 2000-2003 (*.mdb) then, In the Add Reference dialog box, click the COM tab, and then…
