  • Windows XP, have to use ctrl+alt+delete to log on as local administrator

    - by wickedj
    Hey, I have a weird issue, a user was was logging into a laptop using the local admin account which was working fine. I had to create another account on the system, which was also an admin account, when this happened the 'administrator' account disappeared from the 'choose an account to login with' screen. A quick workaround is available, if the user presses ctrl+alt+delete it brings you to the screen where you can type in the username and password, so by manually typing 'administrator' it can log in. Normally this would be easily fixed, I figured the admin account had somehow been disabled from the local system, but i checked all settings and it is setup fine. The laptop is not part of a domain, so I used the management console to delete the new account and all that succeeded in doing was making the 'choose an account to log in with' screen display no accounts to choose. So far I see nothing else to fix it, the option to change the default logon screen to style where you type the username and password also seems to be missing. any ideas?

  • Browser gets blocked, workers to the rescue?

    - by tb_selleo
    Hello, I use JavaScript for rendering 20 tables of 100 rows each. The data for each table is provided by controller as JSON. Each table is split into section that have "totals" and have some other JavaScript logic code. Some totals are outside of the table itself. As a result JavaScript blocks browser for a couple of seconds (especially in IE6) :( I was consideting to use http://code.google.com/p/jsworker/, however Google Gears Workers (I guess workers in general) will not allow me to make changes to DOM at the worker code, and also it seems to me that I can not use jQuery inside jsworker worker code. (Maybe I am wrong here?). This issue seems to be fundamental to the JavaScript coding practice, can you share with me your thoughts how to approach it?

    I have a win32 GUI (MFC) application which I need to port to a WIN CE environment. I keep encountering undefined identifiers. What is the best way to deal with this- is there some site where i can get a mapping of some kind between win32 supported features and corresponding wince features (even if they are not supported, the information that they are not is valuable)

  • Is it possible to upload PHP files to blogspot?

    - by pinaki
    I am trying to create a blog using blogspot. It seems it is not possible to upload anything other than image files to blogspot. I want to upload a PHP file. I managed to upload the file to google sites, but it is coming as downloadable there instead of executing. Is there a work-around here other than buying my own server space?

  • OpenGL coordinates question

    - by Chonch
    Hey, I have a simple OpenGL drawing. When the user changes the window's size, I want the drawing to maintain it's aspect ration. I accomplished that by setting the glViewport to the maximum rectangle with the appropriate aspect ration whenever the reshape method is called. My problem is that I want to draw a square that will always remain in the top right corner of the window, no matter what the size or shape of the window is. Right now, that square moves around the screen whenever the window is reshaped. Can anyone please explain how to do this? Thank you,

  • Easiest Java image processing solution

    - by Daniel Fath
    Here is the deal, in my Java project I have to make a composite document that combines both text and images; So I'm looking for a way to manipulate pictures (rotate, change size, that sort of thing). The API I'm looking for should be clear and easy to learn (preferably with some examples), it should cover the basic transformations I made above - rotate,change size, eventually crop.

  • Is there any danger in calling free() or delete instead of delete[]? [closed]

    - by Matt Joiner
    Possible Duplicate: ( POD )freeing memory : is delete[] equal to delete ? Does delete deallocate the elements beyond the first in an array? char *s = new char[n]; delete s; Does it matter in the above case seeing as all the elements of s are allocated contiguously, and it shouldn't be possible to delete only a portion of the array? For more complex types, would delete call the destructor of objects beyond the first one? Object *p = new Object[n]; delete p; How can delete[] deduce the number of Objects beyond the first, wouldn't this mean it must know the size of the allocated memory region? What if the memory region was allocated with some overhang for performance reasons? For example one could assume that not all allocators would provide a granularity of a single byte. Then any particular allocation could exceed the required size for each element by a whole element or more. For primitive types, such as char, int, is there any difference between: int *p = new int[n]; delete p; delete[] p; free p; Except for the routes taken by the respective calls through the delete-free deallocation machinery?

  • actionscript/flex : fetching assets from a CDN

    - by dta
    I have a peculiar problem. My main.swf loads symbols from other swfs at runtime. If I keep all the swfs(main and others) on my server, things work fine. But if I keep all of them on a CDN, one particular symbol won't display occassionally. With flash tracer plugin for firefox I am able to see that all the symbols have been loaded and their z-indices are as they should be. What could possibly be an issue?

  • XPath to find element based on another XPath element

    - by martymcfly
    Hi, I have an Java AST and I try to find a variable inside it via XPath. Lets say the variable is called 'foobar' I could use //VariableDeclarator/VariableDeclaratorId[@Image='foobar'] but what if I dont know the text 'foobar', but want to read it from another element //VariableDeclarator/VariableDeclaratorId[@Image=//SynchronizedStatement/Expression/PrimaryExpression/PrimaryPrefix/Name] the 'Name' node has the information 'foobar' in @Image, but PrimaryPrefix/Name[@Image] does not work. How must I rewrite the condition //SynchronizedStatement/Expression/PrimaryExpression/PrimaryPrefix/Name that it is the same as @Image='foobar' ? Thanks

  • Is there a way to do simple calculations in a xaml element binding statement other than using a conv

    - by Jonathan Websdale
    In XAML I want to bind the height of one element to be half the height of another element. Is there a way to do this that doesn't involve writing a converter in the code-behind? Example:- What I've got... <Button Name="RemoveButton" Content="Remove Stage" Width="100" Height="{Binding ElementName=AddButton, Path=Height, Converter={StaticResource MyHalfHeightConverter}}"/> What I'd like... <Button Name="RemoveButton" Content="Remove Stage" Width="100" Height="{Binding ElementName=AddButton, Path=(Height / 2.0)}"/>

  • Integer Linear Programming Java: Multiple Open Source and Commercial tools are available. Which one

    - by Sandeep Jindal
    Hi, I need to use Integer Linear Programming API/Tool for my application. Though my application is in Java but I don’t mind calling an EXE (Tool) from Java providing input using file (MPS, etc). My search analysis is as follows: There are multiple Open Source and Commercial tools available to solve ILP Following I found and think are useful for my needs. 1. Gnu LP Kit(GLPK): I think this is the oldest and probably most stable and efficient 2. IP_Solve: Has good reviews about it. 3. JavaILP: Found this, but not much reviews about it 4. Apache Common-Math: Supports LP but not ILP, so ruled out. 5. Coin-OR Can you please suggest which one shall be the best in terms of stability, efficiency, acceptance, etc Regards Sandeep Jindal

  • Kohana v3 ACL A2 with database support

    - by Asif
    Hi, I am using Kohana V 3.0.3. I was looking for ACL library and found from http://dev.kohanaphp.com/projects A2 Kohana's ACL module. Apparently it's found that, it manages Roles,Resources and Rules using config file and authenticate object basis. I want it to be dynamic, like Resources and Rules should be loaded from database dynamically if valid user logs in. Auth part is done now looking for ACL part. Is it possible to use same A2 module with database or need to rewrite own logic?

  • C++ IDE for Linux with smart reference searching

    - by Dmitry Yudakov
    Is there an IDE supporting C++ with REALLY smart searching of references? By 'reference' I mean usage of a class (or its member), variable, function in the whole Project or Workspace. There's lots of IDE providing it. Some of them seem just to search for the text with same name giving lots of stuff, others are smarter and check the context (like class boundaries, namespace) but aren't accurate enough. The best I've tried so far was Visual SlickEdit, but still there's more to wish. class C1 { int foo; }; class C2 { int foo; }; For example in this situation when searching for C1::foo references I don't want C2::foo to be shown too. So, is there an IDE that would be so smart?

  • Forgotten laptop windows login - what are my options?s

    - by Galwegian
    I have a (elderly) colleague who has forgotten the password to his laptop - he generally signs in as Administrator, but can't remember the password, and has asked my help. He says the laptop contains some important data. What are my options? Thanks for any help. EDIT: I have just got hold of the machine and not all is as I was told... The password is not the problem... Before the login box appears I get an error message relating to savedump.exe: The instruction at "0x0..." referenced memory at "0x0...". The memory could not be written. Then when I login using the proper credentials, It logs me in for a tiny second and then logs me out again and 'saves my settings'. Any ideas on this one?

  • choosing the right SSL certifcate

    - by seengee
    Hi All, We're looking to purchase some SSL certificates to secure the login pages of ecommerce sites. It is not required to secure the actual payment process as this is protected by a third party with its own verisign certificate. rapidSSL looks like a good (and cheap) option but a salesperson has told me that they are only suitable for "test sites" and recommended that we use one that is 4 times the cost. Can anyone make any recommendations about what we should be looking for and what we should consider? Thanks.
