  • Logging *Business* Events - use logging framework?

    - by UpTheCreek
    Hi, Something here doesn't feel right to me here, and so I would like the community's input - perhaps I am approaching this in the wrong way.... Q: Is is appropriate to use traditional infrastructure logging frameworks (like log4net) to log business events? When I say business events, I mean I want a global log like this: xx:xx Customer A purchased widget B. xx:xx Widget B was dispatched from warehouse. xx:xx Customer B payment declined. Most traditional infrastructure logging frameworks have event levels something like this: FATAL ERROR WARN INFO DEBUG An of course these messages don't fit well into that. Best description would be INFO, but of course these are important events, and INFO is of very low importance. I would still like this as a 'log' (e.g. I don't want to have to extract this from my business objects each time I want to see it) Seems to me I have two options: 1) Use a framework like log4net and just define a special logger for this (and live with the fact that it doesn't feel right). 2) Provide a service for performing this that doesn't rely on a traditional logging services. I'm leaning towards 2. What has anyone else done in a similar situations? Thanks!

  • Getting Depth Value on Kinect SDK 1.6

    - by AlexanderPD
    this is my first try on Kinect and Kinect SDK so I'm having a lot of "newbie issues" :) my goal is to point my mouse on the Kinect standard video output and get the depth value. I already have both normal video and depth video outputs by using the 2 "Color Basic-WPF" and "Depth Basic-WPF" samples, and handling mouse events or position is not a problem. In fact i already did all and i already got a depth value, but this value is always HIGHLY imprecise. It jumps from 500 to 4000 by just moving to the next pixel in a plane surface. So.. I'm pretty sure I'm reading the depth value in the wrong way. This is how i read it: short debugValue = depthPixels[x*y].Depth; debug.Text = "X = "+x+", Y = "+y+", value = "+debugValue.ToString(); i know it's pretty out of context, this little piece of code is inside the same SensorDepthFrameReady function in "Depth Basic-WPF"! "x" and "y" are the mouse coordinates and depthPixels is DepthImagePixel[] type, a temporary array filled with the "depthFrame.CopyDepthImagePixelDataTo(this.depthPixels);" instruction. Depth frame is filled here: DepthImageFrame depthFrame = e.OpenDepthImageFrame() the "e" comes from here: private void SensorDepthFrameReady(object sender, DepthImageFrameReadyEventArgs e) and this last one is called here: this.sensor.DepthFrameReady += this.SensorDepthFrameReady; how i must handle that depth value i get? I know the value must be between 800 and 4000 but i get values between about 500 and about 8000. i already google a lot (here on SO too) and i still can't understand if the depth value is 11 or 13 bit. The sdk examples uses shrink this value to 8 bit and this is making even more confusion in my head :(

  • Correct Delphi compiler switches to stop in the user's code, not my component's

    - by Jeremy Mullin
    I'm modifying our VCL components so the end user's application links to our dcu files, instead of building our source code each time. We have everything working, but I want the debugger to stop on the user's code when an exception is raised. At first it would stop in our dcu and open the CPU window. I was able to prevent that by removing debug info from the dcu files. But now it still doesn't stop in the users code (like DevExpress libraries and others do). The following screencast is a short example. The first time I cause an exception in the DevExpress code, and the debugger correctly stops in my button event. The second time I cause an exception in my components, but the debugger doesn't have my button event on the call stack, and doesn't show me where the problem was. Any ideas why? http://screencast.com/t/NjhlOTRk Currently building the DCU's with these options: -$W+ -$D- -h -w -q Update: The TDataSet methods in between my component and the button event seem to cause this behavior. If I instead call a direct method of my table, I get the expected behavior. I'm guessing there isn't anything I can do about this, but I'm still curious why it happens.

  • Looking for pros/cons of using GWT or JSF

    - by cliff.meyers
    I'm a long time Java developer who has been building UI with Adobe Flex for the past few years. I'm looking to broaden my repertoire with a RIA technology that runs in a plain-old browser, no plug-ins required. I've read a lot about GWT but don't know much about JSF, especially given the varying implementations. Below are some criteria that are important to me as a developer. I'm hoping that the community might be able to tell me about the strengths and weaknesses of GWT and JSF in each: Layout: is it declarative, programmatic or a mix of both? Control library: how rich is the available control library? How easy is it to extend or write custom controls that "play nice" with the built-ins? Javascript: how much of it do I need to write in order to be successful with the framework? Cross-browser: assuming I'm not writing a lot of my own HTML and JS, do the frameworks function equally well in all modern browsers? Tooling: is a rapid edit/refresh cycle available? How easy is it to debug the client and server code? Bookmarking / Browser Navigation: this is a common problem in Flex; does the framework play nicely with these? I would love to hear any other important pros / cons I might not have covered. Thanks!

  • Private Java class properties mysteriously reset between method calls....

    - by Michael Jones
    I have a very odd problem. A class property is mysteriously reset between method calls. The following code is executed so the constructor is called, then the parseConfiguration method is called. Finally, processData is called. The parseConfiguration method sets the "recursive" property to "true". However, as soon as it enters "processData", "recursive" becomes "false". This problem isn't isolated to a single class -- I have several examples of this in my code. How can this possibly be happening? I've tried initialising properties when they're declared outside any methods, I've tried initialising them in constructors... nothing works. The only complication I can think of here is that this class is invoked by an object that runs in a thread -- but here is one instance per thread, so surely no chance that threads are interfering. I've tried setting both methods to "synchronized", but this still happens. Please help! /** * This class or its superclasses are NOT threaded and don't extend Thread */ public class DirectoryAcquirer extends Manipulator { /** * @var Whether to recursively scan directories */ private boolean recursive = false; /** * Constructor */ public DirectoryAcquirer() { } /** * Constructor that initialises the configuration * * @param config * @throws InvalidConfigurationException */ public DirectoryAcquirer(HierarchicalConfiguration config) throws InvalidConfigurationException { super(config); } @Override protected void parseConfiguration() throws InvalidConfigurationException { // set whether to recurse into directories or not if (this.config.containsKey("recursive")) { // this.recursive gets set to "true" here this.recursive = this.config.getBoolean("recursive"); } } @Override public EntityCollection processData(EntityCollection data) { // here this.recursive is "false" this.logger.debug("processData: Entered method"); } }

  • JQuery object expected error when accessing page via url routing.

    - by Andy Evans
    In my global.asax I have url routing setup like below: routes.MapPageRoute("User Logon", "{Vendor}/Logon", "~/Logon.aspx"); In the logon.aspx page, I have a script that "stylizes" the logon button: <link href="jquery/css/flick/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> <link href="images/style.css" rel="stylesheet" type="text/css" /> <script src="jquery/js/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="jquery/js/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#<%= ButtonLogon.ClientID %>').button(); }); </script> When I access the page us a url (in debug mode) http://localhost/logon.aspx?v=1 the page loads correctly and the jquery button command loads correctly. But then I access the page using the new url route, I get this error. Microsoft JScript runtime error: Object expected Anyone have an idea why this occurs? Thanks.

  • Perl's Devel::LeakTrace::Fast Pointing to blank files and evals

    - by kt
    I am using Devel::LeakTrace::Fast to debug a memory leak in a perl script designed as a daemon which runs an infinite loop with sleeps until interrupted. I am having some trouble both reading the output and finding documentation to help me understand the output. The perldoc doesn't contain much information on the output. Most of it makes sense, such as pointing to globals in DBI. Intermingled with the output, however, are several leaked SV(<LOCATION>) from (eval #) line # Where the numbers are numbers and <LOCATION> is a location in memory. The script itself is not using eval at any point - I have not investigated each used module to see if evals are present. Mostly what I want to know is how to find these evals (if possible). I also find the following entries repeated over and over again leaked SV(<LOCATION>) from line # Where line # is always the same #. Not very helpful in tracking down what file that line is in.

  • How to retrieve the Description property from SettingsProperty?

    - by BadNinja
    For each item in my application's settings, I've added text to its Description Property which I want to retrieve at runtime. I'm sure I'm missing some basic logical nuance here, but everything I've tried has failed. Clearly, my understanding of what value needs to be passed to the Attributes property of the SettingsProperty class is wrong. I'm further confused by the fact that when I iterate through all they keys returned by SettingsProperty.Attributes.Keys, I can see "System.Configuration.SettingsDescriptionAttribute", but when I pass that string in as the key to the Attributes property, null is returned. Any insight into how to properly retrieve the value Description Property would be very much appreciated. Thanks. :) public void MyMethod() { SettingsPropertyCollection MyAppProperties = Properties.Settings.Default.Properties; IEnumerator enumerator = MyAppProperties.GetEnumerator(); // Iterate through all the keys to see what we have.... while (enumerator.MoveNext()) { SettingsProperty property = (SettingsProperty)enumerator.Current; ICollection myKeys = property.Attributes.Keys; foreach (object theKey in myKeys) System.Diagnostics.Debug.Print(theKey.ToString()); // One of the keys returned is: System.Configuration.SettingsDescriptionAttribute } enumerator.Reset(); while (enumerator.MoveNext()) { SettingsProperty property = (SettingsProperty)enumerator.Current; string propertyValue = property.DefaultValue.ToString(); // This fails: Null Reference string propertyDescription = property.Attributes["System.Configuration.SettingsDescriptionAttribute"].ToString(); // Do stuff with strings... } }

  • How to distribute the android reusable code in a package?

    - by Kaillash
    Hi, I have developed some reusable android component which is basically a class . This class has some resource dependencies e.g. some png drawables, some xml layouts etc. So this class referenced the auto-generated R file.I would like to distribute this code in a single package like jar file to other developers for use in their applications. I have read that the only possible solution is to distribute code together with all my resources, which others have to copy to their "res" folder (source). So I created a jar file having the class file (say MyClass which is in the package com.xyz.android.app) and resources and tried to use this in my new application. So I added the jar file to my new applications build path using add external jars option in eclipse and copied all the resources to my new application's res folder. (The activity class say MainActivity of my new application is in com.abc.myapplication package, just for the case if it may helpful) But when I run this new application there is java.lang.ClassCastException in the MyClass class. I tried to debug the application and then I found that in the MyClass class, there is "R cannot be resolved" problem. Then I changed MainActivity's package to com.xyz.android.app (which is not the way, other developers will be happy to do), But again the same problem. But When I just copy the source java file such that both MainActivity.java and MyClass.java are in com.xyz.android.app package then application runs fine. So if I need to distribute such that other users need not to bother these package naming things, how can I accomplish this? Please help !!

    I ran into troubles with MySQL on my CentOS. I had some problems and backed up my database and removed mysql with all dependencies. After that I ran reinstalled: yum groupinstall "MySQL Database" Installed without errors. Running the mysql daemon: service mysqld start Timeout error occurred trying to start MySQL Daemon. Starting MySQL: [FAILED] I also ran # /usr/bin/mysql_install_db --user=mysql Installing MySQL system tables... 120112 1:49:44 [ERROR] Error message file '/usr/share/mysql/english/errmsg.sys' had only 480 error messages, but it should contain at least 481 error messages. Check that the above file is the right version for this program! 120112 1:49:44 [ERROR] Aborting Installation of system tables failed! Examine the logs in /var/lib/mysql for more information. You can try to start the mysqld daemon with: /usr/libexec/mysqld --skip-grant & and use the command line tool /usr/bin/mysql to connect to the mysql database and look at the grant tables: shell> /usr/bin/mysql -u root mysql mysql> show tables Try 'mysqld --help' if you have problems with paths.

  • Very weird C file-handling anomaly

    - by KáGé
    Hello, I got a very weird issue that I cant figure out in my school project, which is the simulation of a simple filesystem in a human-readable textfile. Unfortunately I don't yet have enough time to translate the comments in my code or make it less gibberish, so if you are bothered by that, you don't have to help, I understand. See the code HERE. Now in drive.h, at line 574 is this part: i = getline(); #ifdef DEBUG printf("Free space in all found at %d.\n\n", i); if(drive.disk != NULL){ printf("Disk OK\n\n"); } #endif //write in data state = seekline(i); Before this it finds place for the allocation database entry in the ALL sector (see the "image files" in the mounts folder, this issue was tested on mount_30.efs-dbf), then gets the line with i = getline() fine (getline is in lglobal.h, line 39), but after that any file manipulation (in this case seekline's fseek, but if I comment that out, then the first fprintf after that) crashes the program straight away. I think the file gets somehow corrupted (though the Disk OK message appears) but can't figure out how. I've tried putting i = getline(); into comment, but it didn't make any difference. I've also tried asking at local programming forums but they didn't really help either. The last few lines of the output before it crashes: Dir written. (drive.h line 562) Seekline entered: 268 (called at drive.h line 564) Getline entered. (called at drive.h line 574) Line got: 268. Free space in all found at 268. (drive.h line 576) Seekline entered: 268 (called at drive.h line 582, note that this exact call was run successfully less than 20 lines back. This one should set the pointer to the beginning of the line it is currently in) After this it crashes. Does anyone has any idea of what causes this and how could I fix it? Thank you.

  • Set Custom ASP.NET UserControl variables when its in a Repeater

I think this is the part where I'm missing something. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes["ParentItemID"] = i.ItemID.ToString(); } Any thoughts would be appreciated. Also tried this with similar results... when I debug inside my usercontrol (pfd1) the parameters I am trying to set have not been set. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes.Add("ContainerID", _cid.ToString()); uc.Attributes.Add("ParentItemId", i.ItemID.ToString()); }

  • verifying the signature of x509

    - by sid
    Hi All, While verifying the certificate I am getting EVP_F_EVP_PKEY_GET1_DH My Aim - Verify the certificate signature. I am having 2 certificates : 1. a CA certificate 2. certificate issued by CA. I extracted the 'RSA Public Key (key)' Modulus From CA Certificate using, pPublicKey = X509_get_pubkey(x509); buf_len = (size_t) BN_num_bytes (bn); key = (unsigned char *)malloc (buf_len); n = BN_bn2bin (bn, (unsigned char *) key); if (n != buf_len) LOG(ERROR," : key error\n"); if (key[0] & 0x80) LOG(DEBUG, "00\n"); Now, I have CA public key & CA key length and also having certificate issued by CA in buffer, buffer length & public key. To verify the signature, I have following code int iRet1, iRet2, iRet3, iReason; iRet1 = EVP_VerifyInit(&md_ctx, EVP_sha1()); iRet2 = EVP_VerifyUpdate(&md_ctx, buf, buflen); iRet3 = EVP_VerifyFinal(&md_ctx, (const unsigned char *)CAkey, CAkeyLen, pubkey); iReason = ERR_get_error(); if(ERR_GET_REASON(iReason) == EVP_F_EVP_PKEY_GET1_DH) { LOG(ERROR, "EVP_F_EVP_PKEY_GET1_DH\n"); } LOG(INFO,"EVP_VerifyInit returned %d : EVP_VerifyUpdate returned %d : EVP_VerifyFinal = %d \n", iRet1, iRet2, iRet3); EVP_MD_CTX_cleanup(&md_ctx); EVP_PKEY_free(pubkey); if (iRet3 != 1) { LOG(ERROR,"EVP_VerifyFinal() failed\n"); ret = -1; } LOG(INFO,"signature is valid\n"); I am unable to figure out What might went wrong??? Please if anybody faced same issues? What EVP_F_EVP_PKEY_GET1_DH Error means? Thanks in Advance - opensid

  • Python GUI does not update until entire process is finished

    - by ccwhite1
    I have a process that gets a files from a directory and puts them in a list. It then iterates that list in a loop. The last line of the loop being where it should update my gui display, then it begins the loop again with the next item in the list. My problem is that it does not actually update the gui until the entire process is complete, which depending on the size of the list could be 30 seconds to over a minute. This gives the feeling of the program being 'hung' What I wanted it to do was to process one line in the list, update the gui and then continue. Where did I go wrong? The line to update the list is # Populate listview with drive contents. The print statements are just for debug. def populateList(self): print "populateList" sSource = self.txSource.Value sDest = self.txDest.Value # re-intialize listview and validated list self.listView1.DeleteAllItems() self.validatedMove = None self.validatedMove = [] #Create list of files listOfFiles = getList(sSource) #prompt if no files detected if listOfFiles == []: self.lvActions.Append([datetime.datetime.now(),"Parse Source for .MP3 files","No .MP3 files in source directory"]) #Populate list after both Source and Dest are chosen if len(sDest) > 1 and len(sDest) > 1: print "-iterate listOfFiles" for file in listOfFiles: sFilename = os.path.basename(file) sTitle = getTitle(file) sArtist = getArtist(file) sAlbum = getAblum(file) # Make path = sDest + Artist + Album sDestDir = os.path.join (sDest, sArtist) sDestDir = os.path.join (sDestDir, sAlbum) #If file exists change destination to *.copyX.mp3 sDestDir = self.defineDestFilename(os.path.join(sDestDir,sFilename)) # Populate listview with drive contents self.listView1.Append([sFilename,sTitle,sArtist,sAlbum,sDestDir]) #populate list to later use in move command self.validatedMove.append([file,sDestDir]) print "-item added to SourceDest list" else: print "-list not iterated"

  • Simple jQuery toggle() and return false inside click()

    - by Casey Stark
    I'm mostly a djangonaut and phper, but I'm getting javascript development. I've been looking at this very simple block for a feedback widget on a page. The code is pretty self-explanatory. <a id="feedback-widget-toggle" href="[feedback_url]">Feedback</a> <div id="feedback-widget"> <form method="POST" action="[form_url]"> ... </form> </div> <script type="text/javascript"> $(document).ready(function() { $("#feedback-widget-toggle").click(function() { $("#feedback-widget").toggle("slide", {}, 500); return false; }); }); </script> It's really simple. So simple that I feel pretty dumb for this one. The jQuery is just supposed to disable the link and slide out the feedback-widget div. That's it. I'm new to jQuery, so it's probably some very simple syntax error that I'm not sure how to debug well enough. Thanks.

  • IIS not responding to the few requests from the client

    - by Haroon
    I am stuck with an issue with IIS 7.0. I need someone's help to find resolution on this, as this is very urgent requirement for us. Scenario I am trying to host the service in my server (Windows Server 2008 R2 and IIS 7.0) and my client is running in the XP machine with IIS 5.1. Few of my request sent from client get successful response and for few request I am getting the below exception in Visual studio when I try to debug. Exception in Visual studio 2010 An error occurred while receiving the HTTP response to This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to HTTP request context being aborted by the server (possibly due to the service shutting down). See the server logs for more details. When referred to the server event viewer log I got the below events(Application error and System warning) during the above exception.

  • CakePHP: Missing database table

    - by Justin
    I have a CakePHP application that is running fine locally. I uploaded it to a production server and the first page that uses a database connection gives the "Missing Database Table" error. When I look at the controller dump, it's complaining about the first table. I've tried a variety of things to fix this problem, with no luck: I've confirmed that at the command line I can login with the given MySQL credentials in database.php I've confirmed this table exists I've tried using the MySQL root credentials (temporarily) to see if the problem lies with permissions of the user. The same error appeared. My debug level is currently set to 3 I've deleted the entire contents of /app/tmp/cache I've set 777 permissions on /app/tmp* I've confirmed that I can run DESCRIBE commands at the commant line MySQL when logged in with the MySQL credentials used by by the application I've verified that the CakePHP log file only contains the error I'm setting in the browser window. I've tried all the suggestions I could find in similar postings on SO I've Googled around and didn't find any other ideas I think I've eliminating the obvious problems and my research isn't turning anything up. I feel like I'm missing something obvious. Any ideas?

  • CGLIB proxy error after spring bean definition loading into XmlWebApplicationContext at runtime

    - by VasylV
    I load additional singleton beans definitions at runtime from external jar file into existing XmlWebApplicationContext of my application: BeanFactory beanFactory = xmlWebApplicationContext.getBeanFactory(); DefaultListableBeanFactory defaultFactory = (DefaultListableBeanFactory)beanFactory; final URL url = new URL("external.jar"); final URL[] urls = {url}; ClassLoader loader = new URLClassLoader(urls, this.getClass().getClassLoader()); defaultFactory.setBeanClassLoader(loader); final ClassPathBeanDefinitionScanner scanner = new ClassPathBeanDefinitionScanner(defaultFactory); final DefaultResourceLoader resourceLoader = new DefaultResourceLoader(); resourceLoader.setClassLoader(loader); scanner.setResourceLoader(resourceLoader); scanner.scan("com.*"); Object bean = xmlWebApplicationContext.getBean("externalBean"); After all above xmlWebApplicationContext contains all external definitions of beans. But when i am trying to get bean from context exception is thrown: Couldn't generate CGLIB proxy for class ... I saw in debug mode that in the bean initialization process first time proxy is generated by org.springframework.aop.aspectj.autoproxy.AspectJAwareAdvisorAutoProxyCreator and than it is tried to generate proxy with org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator but fails with mentioned exception.

  • How to tell what account my webservice is running under in Visual Studio 2005

    - by John Galt
    I'm going a little nuts trying to understand the doc on impersonation and delegation and the question has come up what account my webservice is running under. I am logged as myDomainName\johna on my development workstation called JOHNXP. From Vstudio2005 I start my webservice via Debug and the wsdl page comes up in my browser. From Task Manager, I see the following while sitting at a breakpoint in my .asmx code: aspnet_wp.exe pid=1316 UserName=ASPNET devenv.exe pid=3304 UserName=johna The IIS Directory Security tab for the Virtual Directory that hosts my ws.asmx code has "Enable Anonymous access" UNCHECKED and has "Integrated Windows Authentication" CHECKED. So when the MSDN people state "you must configure the user account under which the server process runs", what would they be refering to in the case of my little webservice described above? I am quoting from: http://msdn.microsoft.com/en-us/library/aa302400.aspx Ultimately, I want this webservice of mine to impersonate whatever authenticated domain user browses through to an invoke of my webservice. My webservice in turn consumes another ASMX webservice on a different server (but same domain). I need this remote webservice to use the impersonated domain user credentials (not those of my webservice on JOHNXP). So its getting a little snarly for me to understand this and I see I am unclear about the account my web service uses. I think it is ASPNET in IIS 5.1 on WinXP but not sure.

  • The uncatchable exception, pt 2

    - by chaiguy
    Ok I've done some testing and I've reduced the problem to something very simple: i. Create a method in a new class that throws an exception: public class Class1 { public void CallMe() { string blah = null; blah.ToLower(); } } ii. Create a MethodInfo that points to this method somewhere else: Type class1 = typeof( Class1 ); Class1 obj = new Class1(); MethodInfo method = class1.GetMethod( "CallMe" ); iii. Wrap a call to Invoke() in a try/catch block: try { method.Invoke( obj, null ); // exception is not being caught! } catch { } iv. Run the program without the debugger (works fine). v. Now run the program with the debugger. The debugger will halt the program when the exception occurs, even though it's wrapped in a catch handler that tries to ignore it. (Even if you put a breakpoint in the catch block it will halt before it reaches it!) In fact, the exception is happening when you run it without the debugger too. In a simple test project it's getting ignored at some other level, but if your app has any kind of global exception handling, it will get triggered there as well. This is causing me a real headache because it keeps triggering my app's crash-handler, not to mention the pain it is to attempt to debug.

  • VSC++, virtual method at bad adress, curious bug

    - by antoon.groenewoud
    Hello, This guy: virtual phTreeClass* GetTreeClass() const { return (phTreeClass*)m_entity_class; } When called, crashed the program with an access violation, even after a full recompile. All member functions and virtual member functions had correct memory adresses (I hovered mouse over the methods in debug mode), but this function had a bad memory adress: 0xfffffffc. Everything looked okay: the 'this' pointer, and everything works fine up until this function call. This function is also pretty old and I didn't change it for a long time. The problem just suddenly popped up after some work, which I commented all out to see what was doing it, without any success. So I removed the virtual, compiled, and it works fine. I add virtual, compiled, and it still works fine! I basically changed nothing, and remember that I did do a full recompile earlier, and still had the error back then. I wasn't able to reproduce the problem. But now it is back. I didn't change anything. Removing virtual fixes the problem. Sincerely, Antoon

  • Add two 32-bit integers in Assembler for use in VB6

    - by Emtucifor
    I would like to come up with the byte code in assembler (assembly?) for Windows machines to add two 32-bit longs and throw away the carry bit. I realize the "Windows machines" part is a little vague, but I'm assuming that the bytes for ADD are pretty much the same in all modern Intel instruction sets. I'm just trying to abuse VB a little and make some things faster. So... if the string "8A4C240833C0F6C1E075068B442404D3E0C20800" is the assembly code for SHL that can be "injected" into a VB6 program for a fast SHL operation expecting two Long parameters (we're ignoring here that 32-bit longs in VB6 are signed, just pretend they are unsigned), what is the hex string of bytes representing assembler instructions that will do the same thing to return the sum? The hex code above for SHL is, according to the author: mov eax, [esp+4] mov cl, [esp+8] shl eax, cl ret 8 I spit those bytes into a file and tried unassembling them in a windows command prompt using the old debug utility, but I figured out it's not working with the newer instruction set because it didn't like EAX when I tried assembling something but it was happy with AX. I know from comments in the source code that SHL EAX, CL is D3E0, but I don't have any reference to know what the bytes are for instruction ADD EAX, CL or I'd try it. I tried flat assembler and am not getting anything I can figure out how to use. I used it to assemble the original SHL code and got a very different result, not the same bytes. Help?
