  • Semaphores in unmanaged code

    - by Dororo
    I've been using the Semaphore class to create semaphores. However, the examples use managed code (requires /clr), and I need to use unmanaged code because it seems FreeType doesn't like working with managed code. How can I create two simple threads which use a semaphore in unmanaged code?

  • Create an upload form, select a folder and get a specific file in folder

    - by aladine
    Hi, To upload a single file, it is very simple to use this HTML script: <p> <input type="file" name="input.txt" /> In this question, my task is to select a folder and then get the input.txt inside that folder. The server will response whether input.txt is available or not and to upload it to web server. Is there any way to select a folder instead selecting a file in the input form. Thanks.

  • Displaying Video4Linux frames with LessTif

    - by Dan
    Hi everyone, I have a simple test application (in C) that grabs mmaped frames from my v4l device. And now, I'd like to display these frames within a tiny LessTif application (like gnome cheese, but only displaying the frames - nothing else). Do you have an idea how to implement such a LessTif program? Thanks, Dan

  • What is the purpose of "do!" notation in F#?

    - by Yacoder
    I'm a beginner in F#, so it's a simple question and maybe a duplicate, but I couldn't find the answer anywhere... I'm reading this LOGO DSL implementation and I don't understand, what is the meaning of the "do!" notation in here: this.Loaded.Add (fun _ -> async { do! Async.Sleep 200 for cmd in theDrawing do do! this.Execute(cmd) } |> Async.StartImmediate ) Can you help?

  • Const unsigned char* to char8

    - by BSchlinker
    So, I have two types at the moment: const unsigned char* unencrypted_data_char; string unencrypted_data; I'm attempting to perform a simple conversion of data from one to the other (string - const unsigned char*) As a result, I have the following: strcpy((unencrypted_data_char),(unencrypted_data.c_str())); However, I'm receiving the error: error C2664: 'strcpy' : cannot convert parameter 1 from 'const unsigned char *' to 'char *' Any advise? I thought using reinterpret_cast would help, but it doesn't seem to make a difference.

  • Validate a number between 10 and 11 characters in length

    - by Montana Flynn
    I am using javascript (and PHP) to validate a simple form with a phone number field. I have it working fine checking that the field has only 10 characters, but I really want to check if the field has between 10 and 11 characters. Reason being, some people type numbers like so: 1 555 555 5555 and some people do this 555 555 5555. Here is what I have that works for checking if the length is 10: if (!(stripped.length == 10)) { alert("Please enter a valid US phone number.") return false }

  • Is there a way to change the color of plots in jQuery flot without redrawing the whole chart?

    - by Sam Lee
    I have a chart that I'm drawing using flot. I want to change the colors of the data plots when someone hovers over text. Currently, I am doing this by redrawing the entire chart each time I need to highlight something. This is pretty slow (about 30 milliseconds for a simple chart, as much as 100 for a more complicated chart). Since all I want to do is change the color, is there a faster solution?

  • One-liner to determine who wins in Rock, Paper, Scissors

    - by asmeurer
    So I am writing a simple Rock, Paper, Scissors game in C (it's for an assignment by the way, though the main thing is to learn sockets. Also, I suspect it will be due before I get a good answer). I have it setup as Rock=0, Paper=1, and Scissors=2. Is there an easy one-liner to determine who wins? I tried playing around with it on paper, but I couldn't figure out any patterns.

  • finding "distance" between two pixel's colors.

    - by igor
    Once more something relatively simple, but confused as to what they want. the method to find distance on cartesian coordinate system is distance=sqrt[(x2-x1)^2 + (y2-y1)^2] but how do i apply it here? //Requires: testColor to be a valid Color //Effects: returns the "distance" between the current Pixel's color and // the passed color // uses the standard method to calculate "distance" // uses the same formula as finding distance on a // Cartesian coordinate system double colorDistance(Color testColor) const;

  • Adding a Shadow to a NSImageView

    - by Kevin Sylvestre
    Sorry for the seemingly simple question. I have a NSImageView (added in interface builder) and want to add a shadow outline. I tried using the 'Image View Effects' section of the 'Inspector' but this required enabling a core animation layer. If I set it for the 'Content View' I have very strange appearance side effects. If I set it for the 'Image View' the shadow is cropped (sorry, can't resize the image view). Any ideas?

  • Static Variables in Overloaded Functions

    - by BSchlinker
    I have a function which does the following: When the function is called and passed a true bool value, it sets a static bool value to true When the function is called and passed a string, if the static bool value is set to true, it will do something with that string Here is my concern -- will a static variable remain the same between two overloaded functions? If not, I can simply create a separate function designed to keep track of the bool value, but I try to keep things simple.

  • Why can't I shrink a transaction log file, even after backup?

    - by Jordan Hudson
    I have a database that has a 28gig transaction log file. Recovery mode is simple. I just took a full backup of the database, and then ran both: backup log dbmcms with truncate_only DBCC SHRINKFILE ('Wxlog0', TRUNCATEONLY) The name of the db is db_mcms and the name of the transaction log file is Wxlog0. Neither has helped. I'm not sure what to do next.
