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're in the process of refactoring a large PowerBuilder application with the goal of keeping our business logic in PB and exposing it as an API for .NET developers by using the .NET assembly target in PowerBuilder 12.6 Classic.

The environments we need to support include multi-threaded environments like IIS and xUnit.  In using xUnit (which defaults to running tests in parallel), we've encountered an issue where database connections made on separate threads are interfering with each other.  We've also reproduced this issue from a multi-threaded .NET console application.

We've created a very simple .NET assembly that just exposes a connection nvo that wraps a native PB transaction stored as an instance variable in the class.  We are not using SQLCA or any global variables.  The connection object just has connect and disconnect methods.  We import this assembly into a .NET xUnit project, create three separate test classes where each runs a test that instantiates a local connection instance and loops ten times, just connecting and disconnecting with each iteration.

If we force xUnit to run tests serially (see how below), we can repeatedly run all tests without issue.  If we let xUnit parallelize the execution of the three test classes, we get random errors.  Sometimes after connecting we'll get a "transaction not connected" exception when immediately trying to disconnect or when attempting to connect we'll get a "transaction already connected" exception.  …

Did you know SD-WANs can improve network connectivity? Check out this webinar to learn how an SD-WAN simplified, one-click tool can help you migrate and manage data in the cloud.

At work today where we support an SDK (.net one) someone asked if the C# SDK was a "signed" .NET SDK.

I wasn't 100% sure what they were talking about but I thought this was on the right track:
https://docs.microsoft.com/en-us/dotnet/framework/app-domains/how-to-sign-an-assembly-with-a-strong-name

Can someone explain to me what this is about and why they would need it? And also how difficult would it be to turn my unsigned SDK into a signed SDK?

Thank you

I'm programming Infineon TC29x Aurix Tricore Microcontroller based embedded system in 'C' language.
 
Consider stack starting at address 0x5000 0000.  The stack size is 0x1000.  

If I add 0x1000 to current stack pointer(Register A10) and store result in A10, then I should get underflow error.

What might be the code in assembly to change stack pointer?  something like following:

stw a10, 0x1000(a10)   # I'm not sure if stw is correct opcode ?

what are other options to create stack undeflow exception?

CURRENT STATE: Customer is using IMS DC as legacy online component and IMS-DB & DB2 as backend databases.
 One of the legacy subsystems is Document production which uses ASF & DCF IBM utilities. ASF is for information passing and DCF is for Document production. ASF will get information from user when they submit customer information. Those attributes of information will be made into a virtual file format called SIB Type 1(we can also call it as traditional COPYBOOK). ASF will pass the SIB type 1 file after invoking online PDP(Parameter Determination Program) programs(they are written in assembler language). These PDP program will get some information from backend databases based on the parameters passed in SIB Type 1. They will be displayed to customer by ASF. If customer wants to print all info as letter he can do so with the help of DCF. Following illustration can help to understand the current state.

 Eg:- SIB 1 type 1 file(copybook) contains below fields. These fields will get filled based on the information given by the customer in legacy online screen.
 Policy number
 Surname
 Type of policy

 Now user give policy number (xy123456) as input, ASF will fill the policy number and send this SIB to PDPs like below.

 Policy number : xy123456
 Surname : ???
 Type of policy : ???

 PDP will get invoked by ASF. By following some business logic, the PDP will fill the remaining data in SIB type 1 file and send it to ASF.

 Policy number : xy123456
 Surname : …

I inherited a C# application.  The development environment is Win10 64 bit, VS 2012 and the development machine has Microsoft Office Pro 2016 installed.  The problem is that the C# application has a lot of references to Microsoft.Office.Interop.Word which utilizes MS Office 2003 if I recall correctly (version 11 as opposed to version 14).

I can't get past this build error which states:

Assembly 'Microsoft.Office.Interop.Word, Version 14.0.0.0, culture = neutral, Public Key Token.......' which is a higher version than referenced assembly 'Office, Version=11.0.0.0, Culture neutral....."

I cannot remove the reference to either assembly without breaking a significant amount of the existing code.  I originally tried installing both and setting the 'Embed Interops Types = False' at the recommendation of .Net but that did not resolve the issue.

Any suggestions?

Hi Experts! I have no idea how to debug this issue.... Any help would be appreciated!

I have a client who sends shipments to UPS to get Tracking information and status, etc. Occasionally they have to void an airbill... all the functions work as desired with the exception of the "void" switch.

For example:

Z:\UPS\NewUPS.exe track << works great

Z:\UPS\NewUPS.exe ship << works great

Z:\UPS\NewUPS.exe void << Throws the error (was working a few months ago)

I have a table that has 4 triggers on it.
An api does an insert or update on the table and these triggers fire.

On that same server I have an assembly installed... which a function calls

How can I add a call to that assembly function after the LAST trigger fires?
Is there a way to determine the ORDER of the triggers...
And then should I add that function to the Trigger...??

HI All,

I have this powershell script and I need find a secure way of storing the password. I've tried :

and this will not work.

below is my script, how do I load the assembly, it prompts and error saying :

I am trying to call some routine provided to me by a developer contained in a .dll.

I am working with on-premise 2013 SharePoint and have placed the .dll in the \bin directory.

FROM MSDN:

[You can store compiled assemblies in the Bin folder, and other code anywhere in the web application (such as code for pages) automatically references it. A typical example is that you have the compiled code for a custom class. You can copy the compiled assembly to the Bin folder of your Web application and the class is then available to all pages.

Assemblies in the Bin folder do not need to be installed in the Global Assembly Cache (GAC). The presence of a .dll file in the Bin folder is sufficient for ASP.NET to recognize it.]


My problem is I cant seem to find a way to reference this .dll.

I am using a script editor along with javascript.
Can anyone give me a sample of code to load the library and it's procedures.?

I'm programming Infineon TC29x Aurix Tricore Microcontroller based embedded system in 'C' language.  

Consider stack starting address 0x5000 0000.  The stack size is 0x2000.  

If I take current stack pointer minus 0x2000, will that create stack exception?  If yes, what might be 'C' or assembly language code that will achieve this?

My thought is if I subtract negative 0x2000 from current stack pointer or add 0x2000 to current stack pointer, I'll be outside stack and stack exception will occur ?

 I need to set program counter to illegal address, i.e. 0x00FF FFFC.  Can this be done with assembly language instructions?
 If yes, please instrument assembly language instruction that would set program counter to 0x00FF FFFC while code is running.

Hi everybody, I'm new in assembly 8086.
I tried to print a star every 5 seconds but i didn't succeed.
here is my code:

.model small

.data
star db '*'

.code
start:

mov ax,@data ;initialization
mov ds, ax
mov cl, 0h; save the last time we printed
mov bx,1; using as flag for the first time

pulse:
cli
mov al 0h ;seconds
in al, 070h
out al, 071h ;al=current second(time)
sti

cmp bx,01h
jz initial

sub al,05h; current time-5
cmp cl,al;
jz print
jmp pulse


initial:
dec bx

print:
mov dl,star;
mov ah, 2h
int 21h
mov cl,al; update the last time printed
jmp pulse

end start

my idea was to print a star in the beginning, save this time in the register cl and then to check in any pulse if 5 seconds were past, by subtracting 5 from the new time and compare it to last one.
the problem is that it prints only in the first time and then it stopped printing.
any idea??
thanks a lot!

Okay guys so I know I saw a similar thread like this already but I am still confused as to what my input should be.

I know this function takes in a string of length 6 and then it converts the characters somehow and they need to add up to 0x24 or 36
which can be seen at line <+53>.

The array table gives me values but I have no clue as to what letters correspond with what numbers. If I enter ffffff then masking the numbers for the right most bits gives me f  =  0110 or 6. ffffff = 36 but this still explodes my bomb.

Can someone please help me . Thank you.

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.
