  • Global name not defined

    - by anteater7171
    I wrote a CPU monitoring program in Python. For some reason sometimes the the program will run without any problem. Then other times the program won't even start because of the following error.

  • Test assembly code on a mac

    - by happyCoding25
    Hello, A while back I was following some tutorials an assembly. I was running it all on a windows machine, compiling with NASM and then writing the compiled code to a floppy disk, then reboot and try the code. This process was long and time consuming and sadly was not on a mac. When I found out that Xcode for mac installed NASM I immediately tried to compile some code. The code compiled fine. The issue is testing it. On a mac I have no floppy (not like I want to use one) so Im not sure how to test this. I looked in to Q (kju) and found it would only emulate things on an ISO file. So I guess what Im asking is is it possible to install the compiled code on an ISO file for testing? (Note: the code when compiled forms a .bin file) Thanks for any help

  • Stack / base pointers in assembly

    - by flyingcrab
    I know this topic has been covered ad-naseum here, and other places on the internet - but hopefully the question is a simple one as I try to get my head around assembly... So if i understand correctly the ebp (base pointer) will point to the top of the stack, and the esp (stack pointer) will point to the bottom -- since the stack grows downward. esp therefore points to the 'current location'. So on a function call, once you've saved the ebp on the stack you insert a new stack frame - for the function. So in the case of the image below, if you started from N-3 you would go to N-2 with a function call. But when you are at N-2 - is your ebp == 25 and the esp == 24 (at least initially, before any data is placed on the stack)? Is this correct or am I of on a tangent here? Thanks!

  • jQuery global variable best practice & options?

    - by Kris Krause
    Currently I am working on a legacy web page that uses a ton of javascript, jquery, microsoft client javascript, and other libraries. The bottom line - I cannot rewrite the entire page from scratch as the business cannot justify it. So... it is what it is. Anyway, I need to pollute (I really tried not too) the global namespace with a variable. There are the three options I was thinking - Just store/retrieve it using a normal javascript declaration - var x = 0; Utilize jQuery to store/retrieve the value in a DOM tag - $("body").data("x", 0); Utilize a hidden form field, and set/retrieve the value with jQuery - $("whatever").data("x", 0); What does everyone think? Is there a better way? I looked at the existing pile of code and I do not believe the variable can be scoped in a function.

  • Operand size conflict in x86 Assembly??

    - by Mark V.
    I'm a novice programmer who is attempting assembly for the first time. Sorry in advance if this is an incredibly lame question. I have a character stored in the EAX register, but I need to move it to my DL register. When I try: mov dl, eax I get an error C2443: operand size conflict. I know that the eax register is 32 bit while the dl is 8 bit... am I on to something?? How do I go about solving this.

  • what is the global.asax Application_Start equivalent when using WAS in IIS7

    - by Mike Tours
    Hi I'd like to use the netTcpBinding for my WCF application which is currently hosted in IIS7, which means configuring it to use WAS instead. This is fairly straight forward however, my application previously made use of the Application_Start event in the global.asax file. I do not require access to the httpContext(which I understand access has been removed in IIS7), however I would still like to hook into the start or init methods? Does an equivalent exist when hosting an application in WAS as apposed to IIS7? Using classic mode is not an option(again I'm not interested in the httpcontext and this only appears to work if using an http binding) - and I've seen an example of putting a static class instide the app_code folder which looks like a horrible hack.

  • "Could not load file or assembly" error on trying to access auxillary assemblies from COM

    - by Codex
    We have the project structure as follows: COMExposedCCW.dll -refers- BusinessLayer.dll -refers- Utils.dll COMExposedCCW.dll -refers- Utils.dll The COMExposedCCW.dll has been registered for COM interop. From the COM application{Excel} we can successfully create the CCW object and access its properties, but when we try to invoke methods that refer to the Business/Utils layer, it throws an exception that the file or assembly{Business/Utils} could not be found. The Business/Utils dlls are present in the same folder as the CCW. On copying the Business/Utils to the COM application directory it works fine. I've tried the following: Set "HintPath/" in the CCW project I dont want to dynamically load the assemblies using Reflection {there should be a more elegant solution} Thanks in advance.

  • Using an array in embedded x86 assembly??

    - by Mark V.
    Hey all I have a method (C++) that returns a character and takes an array of characters as its parameters. I'm messing with assembly for the first time and just trying to return the first character of the array in the dl register. Here's what I have so far: char returnFirstChar(char arrayOfLetters[]) { char max; __asm { push eax push ebx push ecx push edx mov dl, 0 mov eax, arrayOfLetters[0] xor edx, edx mov dl, al mov max, dl pop edx pop ecx pop ebx pop eax } return max; } For some reason this method returns a ? Any idea whats going on? Thanks

  • How to get global variable in JQuery functions

    I want to access my global javascript variable in JQuery methods. But I am unable to get it when I go to attach a click even to a div. As following. How can I do that? I mean do I need to rely on hidden fields for some state management? var divCount = 3; $(function() { //divCount is accessible here $("#sortable").sortable({ revert: true }); $("#new").click(function(){ if (divCount<7){ //divCount is not accessible here. why? and how? var thisCount = ++divCount; $("#draggable_"+thisCount).addClass("draggable"); } }); });

  • Increment global variable on click in flash, actionscript 3

    Hi, Making a flash page that can cycle through these three images on mouseclick. For some reason the local changes to count are not reflected on the global one. I tried _global but the syntax was odd and gave me errors. How should I implement this? import flash.events.Event; var images:Array = ["images/image.jpg", "images/image2.jpg", "images/image3.jpg"]; var count:int = 0; forward.addEventListener(MouseEvent.CLICK, loadPhoto); function loadPhoto(evt:Event){ if(count>2){ count==0; } trace(count); imageFrame.source = images[count]; count++; }

  • Declaring local variables in assembly

    - by dcmoebius
    Is it possible to allocate locally-scoped memory in assembly? For example, consider the following (completely contrived) situation: I have two macros, one of which is dependent on the other. The first is: minimum MACRO dest, num1, num2 ; Finds the minimum of two unsigned numbers, stores the result in dest And the second is: tripMin MACRO dest, num1, num2, num3 ; Finds the minimum of three unsigned numbers, stores the result in dest minimum firstMin, num1, num2 minimum secondMin, num2, num3 minimum dest, firstMin, secondMin (I know that this isn't a realistic example for a variety of reasons, but bear with me.) Assuming that all the registers are otherwise occupied, is there any way to declare firstMin and secondMin locally within the macro? Or am I just better off freeing a register by pushing its value onto the stack and popping it back when I'm done?

  • Segmentation Fault when using "mov" in Assembly

    - by quithakay207
    I am working on a simple assembly program for a class, and am encountering an odd segmentation fault. It's a pretty simple program to convert bytes into kilobytes. However, within the function that does the conversion, I get a segmentation fault when I try to move the value 1024 into the ebx register. I've never had this kind of problem before when working with registers. Does someone know what could be causing this? I imagine it is something simple that I'm overlooking. Thank you! asm_main: enter 0,0 pusha mov eax, 0 mov ebx, 0 call read_int push eax call functionA popa mov leave ret functionA: mov eax, [esp + 4] call print_int call print_nl mov ebx, 1024 ;segmentation fault occurs here div ebx call print_int ret UPDATE: One interesting discovery is that if I delete the lines interacting with the stack, push eax and mov eax, [esp + 4], there is no longer a segmentation fault. However, I get a crazy result in eax after performing div ebx.

  • Getting sign of an integer in Assembly

    Hi all, I'm writing some assembly for a project using MASM (32-bit), and I was wondering what would be the easiest way to do this: int delta = A - B; int value = floor((delta + sign(delta)) / 2); Which is basically the following mapping: For 1 < A < 9, and B = 5: A = [1, 2] -> -2 A = [3, 4] -> -1 A = [5] -> 0 A = [6, 7] -> +1 A = [8, 9] -> +1 Any help is much appreciated!

  • Windows API calls from assembly while minimizing program size

    - by takteek
    I'm trying to write a program in assembly and make the resulting executable as small as possible. Some of what I'm doing requires windows API calls to functions such as WriteProcessMemory. I've had some success with calling these functions, but after compiling and linking, my program comes out in the range of 14-15 KB. (From a source of less than 1 KB) I was hoping for much, much less than that. I'm very new to doing low level things like this so I don't really know what would need to be done to make the program smaller. I understand that the exe format itself takes up quite a bit of space. Can anything be done to minimize that? I should mention that I'm using NASM and GCC but I can easily change if that would help.

  • x86 assembly question

    - by kevin
    This is my assembly program which is just a function to swap *x *y. So first argument from main is address of x which is in 8(%ebp) and second one is address of y is in 12(%ebp). The program does swap x and y. I need 7 lines for doing this. can you make it 6 lines and there is a condition you can use only %eax, %ecx, and %edx 3 registers. I think about it so much, but I can't make it 6 lines. There must be a way, isn't it? This might be not a big deal, but if there is a way to get it in 6lines I want to know. movl 8(%ebp), %eax movl (%eax), %ecx movl 12(%ebp), %edx movl (%edx), %eax movl %ecx, (%edx) movl 8(%ebp), %ecx movl %eax, (%ecx)

  • Beginner assembly programming memory usage question

    - by Daniel
    I've been getting into some assembly lately and its fun as it challenges everything i have learned. I was wondering if i could ask a few questions When running an executable, does the entire executable get loaded into memory? From a bit of fiddling i've found that constants aren't really constants? Is it just a compiler thing? const int i = 5; _asm { mov i, 0 } // i is now 0 and compiles fine So are all variables assigned with a constant value embedded into the file as well? Meaning: int a = 1; const int b = 2; void something() { const int c = 3; int d = 4; } Will i find all of these variables embedded in the file (in a hex editor or something)? If the executable is loaded into memory then "constants" are technically using memory? I've read around on the net people saying that constants don't use memory, is this true?

  • Global Import Aliasing in .NET

    - by Josh Stodola
    Using import aliasing in a single class, we can reference class library namespaces by assigning our own custom alias like this: Imports Db = Company.Lib.Data.Objects And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned. Is it possible to do this at the global level so that the alias is applied to the entire solution instead of the given file? Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

  • How to: Inline assembler in C++ (under Visual Studio 2010)

    - by toxic shock
    I'm writing a performance-critical, number-crunching C++ project where 70% of the time is used by the 200 line core module. I'd like to optimize the core using inline assembly, but I'm completely new to this. I do, however, know some x86 assembly languages including the one used by GCC and NASM. All I know: I have to put the assembler instructions in _asm{} where I want them to be. Problem: I have no clue where to start. What is in which register at the moment my inline assembly comes into play?

  • Using different versions of the same assembly.

    - by AngryHacker
    I have a project where I simultaneously must use reports built in ActiveReports 2 and ActiveReports 6. Overall, it works ok, but some of the helper assemblies use the same name. For instance, to be able to export to PDF, both versions use an assembly called ActiveReports.PdfExport.dll. The corresponding assemblies are different, of course. Note that I don't access the ActiveReports.PdfExport.dll directly - this is handled by the ActiveReports runtime. I can't find a way to include both of them into the project. Is there a way? Is GAC the answer?
