Assembly

An assembly language (or assembler language) is a low-level programming language for a computer or other programmable device in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple architectures, but require interpreting or compiling. Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code.

Hi

We have a simple application that was done by a predecessor. All it does is allows users to enter 'item numbers' and send to print. The item data is saved on a separate excel sheet in the same folder. All dll files, EXE. file and excel file are in the same folder. I've just copied this folder to a new machine trying to replicate the process. I can run the application but when I click send to print button on the application I get below error;

"Unhandled exception has occurred in your application if you click continue the application will..."

"could not load file or assembly microsoft.reportviewer.common version=12.0.0.0..."

I've tried installing the relevant files for above exceptions. However, think this is to do more with the 'Print' button on the application and coding behind it.
Please see attached.

Can someone advise what I need to do to get this to work please?

Thanks in advance.

I have a .Net Framework (4.6.1) class library project (call it A).
Then I have a UWP app (call it B), and I want to use the code in A by referencing to A from B. But that is not possible. UWP apps are .Net Core and not compatible with .Net Framework.

So I created a .Netstandard 2.0.3 class library project (call it C), to be a proxy between A and B. I now reference from A (the UWP app) to C (the .Netstandard class library), and then from C to B (the .Net framework class library).

Everything compiles now, but when I run/debug the UWP app in Visual Studio I get the following error originating from the code in A:

System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Web.ApplicationServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.'

System.Web.ApplicationServices is a .Net Framework reference in A, and is not compatible with B. I was hoping to get around this by using .Net standard and C as a proxy between A and B.

Any suggestions on how to fix this?

Code examples won't help here, the code works fine, but not the integration between the various technologies.

Accountant sends us tax returns as password protected PDFs (password needed to open it.  Properties says it was created with Thomson Reuters FileCabinet CS.  The security tab says I can print, copy contents, comment, etc (I can do everything execpt doc assembly and page extraction, whatever those are : )

I click on them in outlook, it opens in Acrobat Reader DC ( free version) - this is on a windows 10 pro machine by the way.

I want to keep a PDF without the password.  So print to PDF?  But they get sooo much larger

Working on it now, he sent a 24 page PDF that is 93kb

trying different apps:

microsoft print to PDF - 673kb
Tried printing with PDF Creator, but it balks because PDF is password protected (to open, and printing is allowed).  WTF!

Tried opening in chrome.  printing w/ microsoft print to pdf made it a 5MB file!  And still can't use pdf creator.

What's a good combination for opening & printing a PDF or some other easy way to strip off password protection to open a PDF

When I compile someone c# code, I got the following warning.  What do I need to resolve this? Any idea?

The primary reference "xxxConfiguration" could not be resolved because it has an indirect dependency on the assembly "xxxAsync, Version=7.05.101.0, Culture=neutral, PublicKeyToken=58aa7495915e0000" which was built against the ".NETFramework,Version=v4.6" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.5".

I have an ASP.NET web forms project, currently running in .net 4.5 version. I am trying to migrate the source code to bitbucket. I pushed the code and compiled the project successfully. when I try to run the project, I get an runtime error shown below -

Could not load file or assembly <add assembly="System.Web.Helpers, Version=2.0.0.0, Culture=neutral  ....

In the project, under references I see system.web.helpers.dll, but the inside the folder  (C:\documents\repos\myproject\bin\System.Web.Helpers.dll )  the dll is not there.

when i go to nuget package manager , and search for system.web.helpers.dll , I can't find it.

Questions -

1. Is this dll no longer available and is replaced by something else?
2. I suppose, when the project was created initially, a reference to dll was added to the project. and looking at the folder path for the dll in the project ( C:\documents\repos\myproject\bin\System.Web.Helpers.dll), when i did a clean build the dll must have been deleted . when the dll was added initially, was it supposed to be in the bin folder?
3. or was this dll availabe in older version of .net ? if i update the .net framework version, I would probably need to update other dlls too, which I am trying to avoid.
4. what are best practices in such situations?

Problem statement: I am trying to do a writeback through .NET assembly stored procedure in SSAS - Multidimensional Cube

Are there any server level settings ? or any additional roles setting?

**Note: User is already an admin.


The .NET code works perfectly fine when debugged from the visual studio, the connection to the server works and the cube update also works.

Issue:
1) When created an assembly using the dll file from .NET class library in the SSAS server, the calling of assembly stored procedure fails and throws error as follows;
a) Assembly Permission set : Safe/External Access
"Executing the query ...
Query (1, 6) Execution of the managed stored procedure UpdateCube failed with the following error: Exception has been thrown by the target of an invocation.Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed..
Run complete"
   
b) Assembly Permission set : Unrestricted
"Executing the query ...
Query (1, 6) Execution of the managed stored procedure UpdateCube failed with the following error: Exception has been thrown by the target of an invocation.An error was encountered in the transport layer.
The peer prematurely closed the connection..
Run complete"

Attached my .cs code which I build to obtain the dll file and then create an assembly on SSAS.

Hi Experts,

I have an application with a reference to Microsoft.SQLServer.BatchParser.dll
I have a problem when I install my application with batchparser (version 9 - SQL2005) and try to update it to batchparser (version 14 - SQL2017)

The assembly is in the directory of the application, but when I try to run the application I get the error message "Could not find file or assembly 'Microsoft.'SqlServer.BatchParser.dll' or one of its dependencies. The specified module could not be found".

Is it possible to update this assembly by copying it to the application directory? Because this is an update, I do not want to manually register or install anything.
I have tried building my application in x86 instead of AnyCPU, but still have the problem.

Hello. I am working with floating point numbers in x86 assembly. I am doing an effort to understand the IEEE 754 document. I have no official document from IEEE. I am running this as an beginner with no budget enough to buy it. That is other problem.

I am facing it learning from open resources. How can I write a custom floating point number and load it into x86 registers? I want to see the program working with exact bits. Example. The program treats the sign bit, the exponent 8 bits and the 23 bits mantissa.

The idea is to supervise the work done. I am using OllyDbg as my tool to see behaviour of the program running in my machine. My machine is x86-based. I am working with Assembly. Some nice C code explaining it could be nice too.

I have no source code yet about this.

Please, thanks.

C# web service calling another .NET assembly using reflection
I use a web service to a run-time assembly call using C# Reflection.
The assembly is in Binary format in database. All records contains a binary data which is almost same in structure. It has a Start method in a class called 'MyAssembly'
First I loads assembly object using  the Binary data, then finds the type - MyAssembly from it and then calls a method 'Start'. The start will write the logs into a directory. This works entirely fine when we call from an executable. All executables goes into separate process ID and the results are getting.

Then calling the same step using a Web service hosted in IIS, the results are getting messed up. Simultaneous calls to the same method gets the results into different different calls.
Example: Method1 called using web service and the logs are writing into File1.
Method1 again called using different arguments and the logs are writing into File2.
When calling method1 two times at the same point of time using web service, gets the logs messed up, File1 details are showing in File2 and File2 are in File1. It is not only the logs issue bug also the execution are getting wrong that inner methods are not getting proper outputs and return values. Everything messed up.

When the web service is calling EXE program (Which is not allowed in so many conditions) - That is without finding out the method using reflection and then calling it, it just calls an exe program using …

I come here, hoping someone will be able to guide me, as to what I need to know about this diagram in order to answer its accompanying questions.

Here is what I know:

  • "Sequential instruction execution" is where each instruction is fetched and executed to completion before the next one begins.
  • The `popl` instruction moves the data element from the top of the stack/register into the specified operand.
  • `%esp` is the stack pointer
