  • Impossible to Remove FTDI driver / FTDI Enumeration on Windows 7

    - by Joe
    I have already read the : Is it possible to reset FTDI virtual com ports enumeration, we easily get hundreds of COM ports in production environment topics which was pretty interesting ! But I got a problem, apparently I can't delete the ftdi driver, so I can't use the previous conclusion of the topic... I'm really stuck and bored of this problem, my com port number is 132 ! Does someone have another solution ?

  • HTML tabindex: Put some links last without complete enumeration

    - by Emanuel Berg
    I know I can use the HTML anchor attribute tabindex to set the tabindex of links, i.e., in what order they get focused when the user hits Tab (or Shift-Tab). But, I have a home page with tons of links, and to enumerate all those is a lot of work. The actual case is, I have four image links that by default gets index 1, 2, 3, and 4 (well, the behavior is equivalent, at least). But, I'd much rather have the first non-image link as number 1. Check it out here and you'll understand immediately. I tried to give the first non-image link (the link I desire to have tabindex 1) - I tried to give it tabindex 1 explicitly, hoping that it would cascade from there, but it didn't (i.e., the first image link got implicit tabindex 2). I also tried to give the image links ridiculously high tabindexes, but that didn't work: as the other links didn't have tabindexes at all, those highs were still "first". As a last resort (the solution currently employed) I gave the image links all tabindex -1. That makes for logical tabbing, but, it is suboptimal, as those image links are excluded from the tab loop - a user tabbing away will probably never realize that the images are clickable. I'd like them to be reachable with tabbing, but last, after all the ordinary links. If you wonder why I'm so determined to achieve this, it has to do with my own finger habits: I almost exclusively search for links, tab back, tab forth, etc., and very seldom using the mouse. Note: I'll accept a script to change the actual HTML for a complete enumeration, if you convince me there is no "set" way to solve this problem.

  • How to setup NTFS ACL with Acces Based Enumeration

    - by Patrick Pellegrino
    We're in the process of migrating from Novell Netware to Windows 2K8 R2 infrastructure (AD, File server, print server... etc) My question is about ACL. While Netware and Windows are totally different, I want to be sure my thnking is good before screwing everything up! There's a scenario : F: | +-- DATA <= Shared as DATA with Access based enumeration | +-- Folder 1 +-- Team 1's Folder +-- Team 2's Folder ... In that case, by default, rights are herited from the F: to the deepest folders. What we want : Administrators group have full control top - down. From DATA, ABE list only folders that users have access. (ex. : I'm in group Team 2, I see Team 2's Folder). From what I understand, at DATA I remove all NTFS ACL to be herited (ex. Users Group), be sure to keep Administrators Group and SYSTEM user. After that, grant Full control (or any right needed) on each folder to Groups or Users that have to have access. Does I'm wrong ? Anything I should take care of ? Any help to my understanding will be very appreciated. Regards.

  • Creating DescriptionAttribute on Enumeration Field using System.Reflection.Emit

    - by Manish Sinha
    I have a list of strings which are candidates for Enumerations values. They are Don't send diffs 500 lines 1000 lines 5000 lines Send entire diff The problem is that spaces, special characters are not a part of identifiers and even cannot start with a number, so I would be sanitizing these values to only chars, numbers and _ To keep the original values I thought of putting these strings in the DescriptionAttribute, such that the final Enum should look like public enum DiffBehvaiour { [Description("Don't send diffs")] Dont_send_diffs, [Description("500 lines")] Diff_500_lines, [Description("1000 lines")] Diff_1000_lines, [Description("5000 lines")] Diff_5000_lines, [Description("Send entire diff")] Send_entire_diff } Then later using code I will retrieve the real string associated with the enumeration value, so that the correct string can be sent back the web service to get the correct resource. I want to know how to create the DescriptionAttribute using System.Reflection.Emit Basically the question is where and how to store the original string so that when the Enumeration value is chosen, the corresponding value can be retrieved. I am also interested in knowing how to access DescriptionAttribute when needed.

  • Loop on enumeration values

    - by Rachel
    How awful is it - or is it perfectly acceptable - to index a loop on an enumeration? I have an enumeration defined. The values of the literals are default values. The assigned values do not have any significance, will not have any significance, and the values of any literals added in the future will also not have any significance. It's just defined to limit the allowed values and to make things easier to follow. Therefore the values will always start at 0 and increase by 1. Can I set up a loop like so: enum MyEnum { value1, value2, value3, maxValue } for(MyEnum i = value1; i < maxValue; i = static_cast<MyEnum>(i+1)){}

  • Strange thing about .NET 4.0 filesystem enumeratation functionality

    - by codymanix
    I just read a page of "Whats new .NET Framework 4.0". I have trouble understanding the last paragraph: To remove open handles on enumerated directories or files Create a custom method (or function in Visual Basic) to contain your enumeration code. Apply the MethodImplAttribute attribute with the NoInlining option to the new method. For example: [MethodImplAttribute(MethodImplOptions.NoInlining)] Private void Enumerate() Include the following method calls, to run after your enumeration code: * The GC.Collect() method (no parameters). * The GC.WaitForPendingFinalizers() method. Why the attribute NoInlining? What harm would inlining do here? Why call the garbage collector manually, why not making the enumerator implement IDisposable in the first place? I suspect they use FindFirstFile()/FindNextFile() API calls for the imlementation, so FindClose() has to be called in any case if the enumeration is done.

  • Windows server 2008 - Access Based Enumeration (ABE) not working correctly

    - by Napster100
    I have a folder shared with permissions of only one user account, admin account and admin group having access to it, but when I open the shared area from a second user account which dose not have access to it, the folder is still visible to the second account despite ABE being enabled on it and all other parent directories/folders and even the the drive. The user can't access the shared folder (which is what I want), but I'd like the folder to also be invisible to that user, just to make it look cleaner and theirs no confusion between what they can access and what they cannot. How would I stop the folder appearing for users who don't have permissions to use it? Thanks in advanced. EDIT: I've just added the second user account to the permissions list but denied it access so that the account definitely has no permissions to access it in any way but that's still not hiding it.

  • DShow : Enumeration sequence of IEnumMoniker

    - by KenC
    Hello, This is a question about DirectShow IEnumMoniker. Out of some reason, I have to know "what kind of order" IEnumMoniker enumerates items. (I mean, it's alphabetically or...?) The following pages are documents about IEnumMoniker, however, it doesn't mention about this : http://msdn.microsoft.com/en-us/library/ms692852(v=VS.85).aspx http://msdn.microsoft.com/en-us/library/dd407292%28VS.85%29.aspx If anybody has the idea about the enumeration sequence, please let me know. Thanks a lot.

  • Fast method of directory enumeration on Win32?

    - by BillyONeal
    Hello everyone :) I'm trying to speedup directory enumeration in C++, where I'm recursing into subdirectories. I currently have an app which spends 95% of it's time in FindFirst/FindNextFile APIs, and it takes several minutes to enumerate all the files on a given volume. I know it's possible to do this faster because there is an app that does: Everything. It enumerates my entire drive in seconds. How might I accomplish something like this?

  • How to use enumeration types in C++?

    - by Sagistic
    I do not understand how to use enumeration types. I understand what they are, but I don't quite get their purpose. I have made a program that inputs three sides of a triangle and outputs whether or not they are isosceles, scalene, or equilateral. I'm suppose to incorporate the enumeration type somewhere, but don't get where and how to use them. Any help would be appreciated. #include <iostream> using namespace std; enum triangleType {scalene, isosceles, equilateral, noTriangle}; void triangleShape(double x, double y, double z); int main() { double x, y, z; cout << "Please enter the three sides of a triangle:" << endl; cout << "Enter side 1: "; cin >> x; cout << endl; cout << "Enter side 2: "; cin >> y; cout << endl; cout << "Enter side 3: "; cin >> z; cout << endl; triangleShape(x, y, z); return 0; } void triangleShape(double x, double y, double z) { if (((x+y) > z) && ((x+z) > y) && ((y+z) > x)) { cout << "You have a triangle!" << endl; if (x == y && y == z) cout << "Your triangle is an equilateral" << endl; else if (x == y || x == z || y == z) cout << "Your triangle is an isosceles" << endl; else cout << "Your triangle is a scalene" << endl; } else if ((x+y) <= z || ((x+z) <= y) || ((y+z) <= x)) cout << "You do not have a triangle." << endl; }

  • creating enumeration using .NET's CodeDom

    - by Manish Sinha
    Hi, I want to create an Enumeration using CodeDom API. I have searched enough on the internet and I get results which are hardly of any use. What I want to generate is public enum bug_tracker_type { [Description("Bugzilla")] Bugzilla, [Description("Debbugs")] Debbugs, [Description("PHP Project Bugtracker")] PHP_Project_Bugtracker, [Description("Google Code")] Google_Code } I used CodeTypeDeclaration and set it's IsEnum property as true, created a name, and set it's Attributes. Now the biggest problem is how to populate the body? I tried CodeTypeMember mem = new CodeTypeMember(); mem.Name = WadlSharpUtils.CreateIdentifier(discreteValue.value); mem.CustomAttributes.Add(new CodeAttributeDeclaration(discreteValue.value)); // enumCandidate is an instance of CodeTypeDeclaration enumCandidate.Members.Add(mem); Though using this solution I can generate the Description attributes, the end of line would be ; and not ,

  • USB enumeration failure in ColdFire MCF52259

    - by Quicksilver
    Anybody with programming experience on the ColdFire line, please help! I'm using the CMX USB-Lite stack with the ColdFire MCF52259. For some reason, USB enumeration fails at the very first step, as soon as I enable the DP pull-up resistor. This is what I'm doing :- INT_ENB, OTG_INT_EN, ERR_ENB are set to 0x0 INT_STAT, OTG_INT_STAT and ERR_STAT are set to 0xff (This should clear all interrupts) In the Interrupt Status Register, bits 0 (Mask All) and 53 are made 0, all others are 1. TOK_DNE, USB_RST and STALL interrupts are enabled in INT_ENB. BDT base address is set. MCF_USB_CTL holds 0x1 PROBLEM: After the host issues the first reset (at which point I enable Control endpoint 0), instead of the expected Get Descriptor request I'm getting an endless series of resets. At least, that's what it looks like, because the TOK_DNE interrupt never triggers. Is there anything I'm doing wrong?

  • Scala - Enumeration vs. Case-Classes

    - by tzofia
    I've created akka actor called LogActor. The LogActors's receive method handling messages from other actors and logging them to the specified log level. I can distinguish between the different levels in 2 ways. The first one: import LogLevel._ object LogLevel extends Enumeration { type LogLevel = Value val Error, Warning, Info, Debug = Value } case class LogMessage(level : LogLevel, msg : String) The second: (EDIT) abstract class LogMessage(msg : String) case class LogMessageError(msg : String) extends LogMessage(msg) case class LogMessageWarning(msg : String) extends LogMessage(msg) case class LogMessageInfo(msg : String) extends LogMessage(msg) case class LogMessageDebug(msg : String) extends LogMessage(msg) Which way is more efficient? does it take less time to match case class or to match enum value? (I read this question but there isn't any answer referring to the runtime issue)

  • Enumeration classes in Java

    - by Crystal
    I have one class that declares an enumeration type as: public enum HOME_LOAN_TERMS {FIFTEEN_YEAR, THIRTY_YEAR}; Is this type usable in another class? I'm basically trying to complete a homework assignment where we have two types of loans, and one loanManager class. When I try to use the HOME_LOAN_TERMS.THIRTY_YEAR in my loanManager class that does not extend or implement the loan class, I get an error saying it 'cannot find symbol HOME_LOAN_TERMS.' So I did not know if my loanManager class needed to implement the two different loan classes. Thanks.

  • why does entity framework+mysql provider enumeration returns partial results with no exceptions

    - by Freddy Rios
    I'm trying to make sense of a situation I have using entity framework on .net 3.5 sp1 + MySQL 6.1.2.0 as the provider. It involves the following code: Response.Write("Products: " + plist.Count() + "<br />"); var total = 0; foreach (var p in plist) { //... some actions total++; //... other actions } Response.Write("Total Products Checked: " + total + "<br />"); Basically the total products is varying on each run, and it isn't matching the full total in plist. Its varies widely, from ~ 1/5th to half. There isn't any control flow code inside the foreach i.e. no break, continue, try/catch, conditions around total++, anything that could affect the count. As confirmation, there are other totals captured inside the loop related to the actions, and those match the lower and higher total runs. I don't find any reason to the above, other than something in entity framework or the mysql provider that causes it to end the foreach when retrieving an item. The body of the foreach can have some good variation in time, as the actions involve file & network access, my best shot at the time is that when the .net code takes beyond certain threshold there is some type of timeout in the underlying framework/provider and instead of causing an exception it is silently reporting no more items for enumeration. Can anyone give some light in the above scenario and/or confirm if the entity framework/mysql provider has the above behavior? Update: I can't reproduce the behavior by using Thread.Sleep in a simple foreach in a test project, not sure where else to look for this weird behavior :(.

  • Enumerations and String values in ASP.NET

    - by Jason
    I'm looking for some best practice advice on enumerations and retrieving an associated string value. Given this: public enum SerialKillers { TedBundy, EdGein, AlbertFish, GeorgeBush } What is the best way to get a related string value of the name? Eg. "Ted Bundy", given that the string value may not match the representation in the enumeration. eg "George W Bush" My current thinking is function accepting an enum and returning a string, but would that not mean hard coding the string values (which I prefer not to do)? Is using a resources file where the string can be retrieved via the enumeration too heavy handed? Should I accept the fact I am going to Hell for victimising Ted Bundy by associating him with George Bush?
