  • Shell complains 'cannot execute binary file'

    - by Negai
    Hi everyone, I've playing around with linux and noticed that for some mysterious reason commands like '/bin/sh ' just will not work. Each time I'm trying to start a process it yields 'cannot execute binary file' error message. m@sanctuary:~$ sh sed /bin/sed: /bin/sed: cannot execute binary file When I first launch sh and try to execute sed, it succeeds. I'm starting to loose my wits. It would be just great, if somebody could help me. Thank you.

  • Modifying resource contents of a running executable

    - by mrwoik
    All, I store my application settings in a resource. When my program first loads, I read the specified resource using WinAPI. I then parse the retrieved byte data. This works flawlessly for me. Now let's say that a user alters a setting in my application. He/she checks a checkbox control. I would like to save the updated setting to my resource. However, it seems that my call to UpdateResource will not work while my application is running. I can't modify my resource data even though it is the same size. First, is it possible to modify a running image's resource data? Second, if that is not possible, what alternatives do I have for storing settings internally within my application? NOTE: I must have the settings within my running executable. They cannot be on the harddrive or in the registry. Please don't even suggest that as an option.

  • How do I set a resource file to non-embedded

    - by themaninthesuitcase
    In Visual studio 2008 is it possible to have a resource file that is included as a separate file after compilation rather than as an embedded resource. This is to enable small changes to be rolled out more easily. I have tried build options of Resource, None, Compile and also copy local on and off for most of these. However when ever I try access the resource at run time I get a cannot find resource exception. Is this actually possible or am I wasting my time?

  • What are the downside of not having an index.html file to some directories

    - by Pennf0lio
    Hi, I'm curious what are some effects/downside of not putting an index.html file to your directories (e.g images). I know when an index file is not present to a directory, files inside that directory are no longer private and will be visible to the browsers when point (eg yoursite.com/images/). Aside from that what are some big effects to consider? and how to properly secure them. thanks!

  • How would I implement code in a .h file into the main.cpp file?

    - by Lea
    I have a c++ project I am working on. I am a little stumped at the moment. I need a little help. I need to implement code from the .h file into the main.cpp file and I am not sure how to do that. For example code code from main.cpp: switch (choice){ case 1: // open an account { cout << "Please enter the opening balence: $ "; cin >> openBal; cout << endl; cout << "Please enter the account number: "; cin >> accountNum; cout << endl; break; } case 2:// check an account { cout << "Please enter the account number: "; cin >> accountNum; cout << endl; break; } and code from the .h file: void display(ostream& out) const; // displays every item in this list through out bool retrieve(elemType& item) const; // retrieves item from this list // returns true if item is present in this list and // element in this list is copied to item // false otherwise // transformers void insert(const elemType& item); // inserts item into this list // preconditions: list is not full and // item not present in this list // postcondition: item is in this list In the .h file you would need to use the void insert under transformer in the main.cpp under case 1. How would you do that? Any help is apprecaited. I hope I didn't confuse anyone on what I am needing to know how to do. Thanks

  • php convert images and upload to amazon s3

    - by faraklit
    I am looking for a best practice while uploading images to amazon s3 server and serving from there. We need four different sizes of an image. So just after image upload we convert the image and scale in 4 different widths and heights. And then we send them to the amazon s3 using official php api. // ... // image conversions, bucket setting, s3 initialization etc. $sizes= array("", "48", "64", "128"); foreach($sizes as $size) { $filename = $upload_path.$dest_file.$size.$ext; $s3->batch()->create_object($bucket, , array( 'fileUpload' => $filename, 'acl' => AmazonS3::ACL_PUBLIC, )); } But for a 1M image the client sometimes wait up to 30 seconds which is a very long time. Instead of sending images immediately to S3, it may be better to add them to a job queue. But the user should see the uploaded image immediately.

  • How to post data in PHP using file_get_contents?

    - by Paras Chopra
    I am using PHP's function file_get_contents() to fetch contents of a URL and then I process headers through the variable $http_response_header. Now the problem is that some of the URLs need some data to be posted to the URL (for example, login pages). How do I do that? I realize using stream_context I may be able to do that but I am not entirely clear. Thanks.
