Xforce Keygen 64-bit Alias Design 2014 Keygen
Cherrie Patete
When I switched from Windows 7 to Windows 10 on this machine, I installed SSMS V16, and noticed then that there were no 64-bit nodes in SSCM. I didn't think too much of it at the time, and set about creating my 32-bit aliases.
I have SQL Server installed on another machine. I want my application to connect to a database on that machine, remotely. To make it easier to manage the remote database I have SSMS installed locally; in that way, I don't have to use RDP to connect to the server. When I run my application and it connects to the remote database, I want to use an alias, such as 'MyRemoteDatabase', instead of using the IP address and port number directly. In the past, I have run SSCM to create the alias, but my 64-bit applications don't see my 32-bit aliases, which is why I want the 64-bit nodes.
We ran into this problem because we installed SQL Server 2016 and then the latest version of SSMS (17.9). The problem is that SSMS installed the "SQL Server 2017" folder and configuration tools in the start menu. If you open the config manager for 2017 you only see the 32-bit network settings. You have to open the SQL Server 2016 configuration manager to see everything. Basically the same thing @ericb said - you need to open the config manager that was installed with your server, not the one installed by SSMS.
In my case, I was dealing with a SQL 2008 R2 installation. I needed to add Read & Execute Permission for the local Users group to:C:\Program Files\Microsoft SQL Server\100\Shared even though my user account and all groups of which my account is a member had explicit permissions to that folder.
Clients connect to these servers using TCP/IP without any problem, telnet works on IP/Port I use for my alias, the firewall exceptions are created, basically everything works fine, except when I create an alias, I can not connect through it to my server using either TCP/IP or named pipes (local or one of other servers).
I've installed latest cumulative updates, which updates native client too (which I think is the source of problem) and I still have the problem. The stranger part is, if I create an alias on a server with sql server 2005 (native client 9), I can connect to my 2008 r2 instances. Any suggestions?
After you are sure, that it's not firewall problem, TCP/IP problem, and you can connect to server regularly without using alias and only have a problem to connect with alias, I have this problem on Vista and Windows 7.
For me it was the sequence of creating the aliases that was important. See this link: W2K8 R2 SQL Alias will not connectI started by deleting everything, CliConfig aliases and Configuration Manager Native Client config aliases. Then re-create, adding the CLICONFG version first.
For me, the answer was to use the 32-bit CLICONFG. Both Management Studio and the application I was trying to install were 32-bit applications on a 64-bit server. Moral of the story is to create both 64-bit and 32-bit aliases.
If you are using default instances are you running on a x64 platform? There are aliases for 32bit and 64bit so SSMS on the same box as the database engine would use the alias under the 32 bit section even though the box is 64bit
Microsoft Visual Basic for Applications (VBA) is the version of Visual Basic that ships with Microsoft Office. In Microsoft Office 2010, VBA includes language features that enable VBA code to run correctly in both 32-bit and 64-bit environments.
Running VBA code that was written before the Office 2010 release (VBA version 6 and earlier) on a 64-bit platform can result in errors if the code is not modified to run in 64-bit versions of Office. Errors will result because VBA version 6 and earlier implicitly targets 32-bit platforms, and typically contains Declare statements that call into the Windows API by using 32-bit data types for pointers and handles. Because VBA version 6 and earlier does not have a specific data type for pointers or handles, it uses the Long data type, which is a 32-bit 4-byte data type, to reference pointers and handles. Pointers and handles in 64-bit environments are 8-byte 64-bit quantities. These 64-bit quantities cannot be held in 32-bit data types.
The problem with running legacy VBA code in 64-bit Office is that trying to load 64-bits into a 32-bit data type truncates the 64-bit quantity. This can result in memory overruns, unexpected results in your code, and possible application failure.
To address this problem and enable VBA code to work correctly in both 32-bit and 64-bit environments, several language features have been added to VBA. The table at the bottom of this document summarizes the new VBA language features. Three important additions are the LongPtr type alias, the LongLong data type, and the PtrSafe keyword.
All Declare statements must now include the PtrSafe keyword when running in 64-bit versions of Office. It's important to understand that simply adding the PtrSafe keyword to a Declare statement only signifies that the Declare statement explicitly targets 64-bits. All data types within the statement that need to store 64-bits (including return values and parameters) must still be modified to hold 64-bit quantities.
Consider the following Declare statement examples. Running the unmodified Declare statement in 64-bit versions of Office will result in an error indicating that the Declare statement does not include the PtrSafe qualifier. The modified VBA example contains the PtrSafe qualifier, but notice that the return value (a pointer to the active window) returns a Long data type. On 64-bit Office, this is incorrect because the pointer needs to be 64-bits. The PtrSafe qualifier tells the compiler that the Declare statement is targeting 64-bits, so the statement executes without error. But because the return value has not been updated to a 64-bit data type, the return value is truncated, resulting in an incorrect value returned.
To reiterate, you must modify the Declare statement to include the PtrSafe qualifier, and you must update any variables within the statement that need to hold 64-bit quantities so that the variables use 64-bit data types.
In summary, for code to work in 64-bit versions of Office, you need to locate and modify all existing Declare statements to use the PtrSafe qualifier. You also need to locate and modify all data types within these Declare statements that reference handles or pointers to use the new 64-bit compatible LongPtr type alias, and types that need to hold 64-bit integrals with the new LongLong data type. Additionally, you must update any user defined types (UDTs) that contain pointers or handles and 64-bit integrals to use 64-bit data types, and verify that all variable assignments are correct to prevent type mismatch errors.
Note that if you require different logic to execute, for example, you need to manipulate 64-bit values in large Excel projects, you can use the Win64 conditional compilation constant as shown in the following section.
To write code that can work in both new and older versions of Office, you can use a combination of the new VBA7 and Win64 conditional Compiler constants. The Vba7 conditional compiler constant is used to determine if code is running in version 7 of the VB editor (the VBA version that ships in Office 2010). The Win64 conditional compiler constant is used to determine which version (32-bit or 64-bit) of Office is running.
How bad would it be if I created an application that compiled with the 64-bit version initially, but was somehow mistakenly linked with the 128-bit version through bad linker shenanigans or other trickery?
You would think adding more undefined behavior to the C Standard would be a bad thing, especially when it was defined before. Unfortunately, implementations diverged and they wanted to stay diverged. Nobody was willing to change their behavior after DR 400. So, of course,
The link there explains it fairly succinctly, but this allows an implementation to, effectively, rename the symbol that ends up in the binary, without changing your top level code. That is, given this code:
The paper document that describes the work done here is N2901. It contains much of the same statement of the problem that is found in this post, but talks about the development of a solution. In short, what we develop here is a way to provide a symbol that does officially exist as far as the final binary is concerned, much like how the asm("new_name") and __attribute__((alias("old_name"))) are. Notably, the design has these goals:
Is a compiler allocating something on the heap when the size is predictable and it could be on the stack instead? QoI. Does your nested function implementation mark your stack as executable code rather than dynamic allocation to save space, opening you up to some nasty security vulnerabilities when some buffer overflows get into the mix? QoI. Does what is VERY CLEARLY a set of integer operations meant to be a rotate left not get optimized into a single rotl assembly instruction, despite all the ways you attempt to cajole the code to make the compiler do that?
Now, could a compiler be hostile enough to implement it the worst possible way? Yes, sure, but having an existence proof and writing a specification that strictly conforms to the same kind of transparency allows most non-asshole compiler vendors to do the simple (and correct) thing for the featureset. But why does this work? How does it solve our ABI problem?
No longer a theoretical idea, this is an existence proof that we can create backwards-compatible shared libraries on multiple different platforms that allow for seamless upgrading. A layer of indirection between the name the C code sees and uses for its functions versus what the actual symbol name effectively creates a small, cross-platform, compile-time-only symbol presevation mechanism. It has no binary size penalty beyond what you, the end user, decide to use for any additional symbols you want to add to old shared libraries. No old symbols have to be messed with, solving the shared library problem. Having an upgrade path finally stops dragging along the technical liability of things chosen from well before I was even born:
