  • Including Libraries C++

    - by m00st
    How do I properly include libraries in C++? I'm used to doing the standard libraries in C++ and my own .h files. I'm trying to include wxWidgets or GTK+ in code::blocks and/or netbeans C/C++ plugin. I've included ALL libraries but I constantly get errors such as file not found when it is explicitly in the include! One error: test1.cpp:1:24: wx/msw/wx.rc: No such file or directory : Yes the .h file library is included; what am I missing? Do I need to be importing other things as well? Is there a tutorial for this? Obviously my shoddy textbook hasn't prepared me for this.

  • How to save multiple UIImage to a file iPad

    - by aron
    I have a PDF reader that displays pages of the document. What I want to do is allow the user to draw over the PDF in a transparent view. Then I want to save the drawing (UIImage) to disk. If at all possible, I don't want to have the documents folder filled with files like documentName_page01.png, documentName_page02.png for every page that is drawn over. However, I can't figure out how to store these UIImages into a single file without it becoming unwieldy and memory intensive. Any ideas appreciated.

  • Are indexes good or bad for a large database?

    - by gmemon
    Hello All, I read on MySQL Performance Blog that when tables are large, it is better to scan full tables, instead of using indexes. I have a table with tens of millions of rows. When conducting queries, if I use no indexes, then queries are 24 times slower than with indexes. I know lot of things may cause this (e.g., are rows stored sequentially), but can you please give me some hints what might be happening? Or how I should start examining this issue? I want to understand when use of indexes is preferred and when it's not Thanks

  • Construct Numpy index given list of starting and ending positions

    - by Abiel
    I have two identically-sized numpy.array objects (both one-dimensional), one of which contains a list of starting index positions, and the other of which contains a list of ending index positions (alternatively you could say I have a list of starting positions and window lengths). In case it matters, the slices formed by the starting and ending positions are guaranteed to be non-overlapping. I am trying to figure out how to use these starting and ending positions to form an index for another array object, without having to use a loop. For example: import numpy as np start = np.array([1,7,20]) end = np.array([3,10,25]) Want to reference somearray[1,2,7,8,9,20,21,22,23,24])

  • size of structures in .NET

    - by redpaladin
    My problem is very simple. My problem is to send a structure between a program in C to a C# program. I made a struct in C#: public struct NetPoint { public float lat; // 4 bytes public float lon; // 4 bytes public int alt; // 4 bytes public long time; // 8 bytes } Total size of the struct must be 20 bytes. When I do a sizeof() of this struct: System.Diagnostics.Debug.WriteLine("SizeOf(NetPoint)=" + System.Runtime.InteropServices.Marshal.SizeOf(new NetPoint())); The debug console shows: SizeOf(NetPoint)=24 But I expected to have 20 bytes. Why do I see a difference?

  • C++ shifting bits

    - by Bobby
    I am new to shifting bits, but I am trying to debug the following snippet: if (!(strcmp(arr[i].GetValType(), "f64"))) { dem_content_buff[BytFldPos] = tmp_data; dem_content_buff[BytFldPos + 1] = tmp_data >> 8; dem_content_buff[BytFldPos + 2] = tmp_data >> 16; dem_content_buff[BytFldPos + 3] = tmp_data >> 24; dem_content_buff[BytFldPos + 4] = tmp_data >> 32; dem_content_buff[BytFldPos + 5] = tmp_data >> 40; dem_content_buff[BytFldPos + 6] = tmp_data >> 48; dem_content_buff[BytFldPos + 7] = tmp_data >> 56; } I am getting a warning saying the lines with "32" to "56" have a shift count that is too large. The "f64" in the predicate just means that the data should be 64bit data. How should this be done?

  • Can you use MongoDB map/reduce to migrate data?

    - by Brian Armstrong
    I have a large collection where I want to modify all the documents by populating a field. A simple example might be caching the comment count on each post: class Post field :comment_count, type: Integer has_many :comments end class Comment belongs_to :post end I can run it in serial with something like: Post.all.each do |p| p.udpate_attribute :comment_count, p.comments.count end But it's taking 24 hours to run (large collection). I was wondering if mongo's map/reduce could be used for this? But I haven't seen a great example yet. I imagine you would map off the comments collection and then store the reduced results in the posts collection. Am I on the right track?

  • How can I convert a specific .cs file into either a .bat or a .exe file?

    - by user2974969
    I am trying to convert around 1,900 .txp files (a proprietary Sony image format) to .png. However, the .exe program I am using to convert these files only allows me to select one file at a time. I am running Windows 7. There's a TXP.CS file in the 'src' folder of the program, so I figured that if I was able to turn that into an executable file, I'd be able to use it to mass convert these files to PNG. However, whenever I try to convert the file using csc.exe, I get the CS0246 error (the type or namespace name 'Tools' could not be found. Are you missing a using directive or an assembly reference?). I can't use Microsoft Visual Studio right now, so I'm hoping someone can walk me through this, or maybe convert the file to either a .bat or an .exe for me. Thank you. TXP.CS

  • Table character encoding - exception in application

    - by zgnilec
    I have a code: CREATE TABLE IF NOT EXISTS Person ( name varchar(24) ... ) CHARACTER SET utf8 COLLATE utf8_polish_ci; This works OK in my application, but I read if someone put in name field a string that contains character wchich code is greater than 127, database will use 2 bytes (or more) to store this character. So i think, i will change character set to utf16: CHARACTER SET utf16 COLLATE utf16_polish_ci; But now when I run my application, exception apears: KeyNotFoundException. It apears exactly at these instructions: MySqlCommand komenda = baza.Polaczenie.CreateCommand (); komenda.CommandText = zapytanie; MySqlDataReader dr = komenda.ExecuteReader (); // HERE, at execute reader method if (dr.Read ()) ... 1) Anyone had similar problem? 2) Any idea how to use always 2 bytes/char in database field?

  • How can I output the fitted values?

    - by zenbomb
    Sorry if this is a novice question, but I don't understand it. I am fitting a sigmoid curve to my data with glm(). This works, I can plot the output and I see a nice sigmoid curve. However, how do I get R to return the final values it has fit? As I understand it, R fits the data to logit(y) = b0 + b1x, but when I do > summary(glm.out) I only get Call: glm(formula = e$V2 ~ e$V1, family = binomial(logit), data = e) Deviance Residuals: 1 2 3 4 5 6 7 -0.00001 -0.06612 -0.15118 -0.34237 0.20874 0.08724 -0.19557 Coefficients: Estimate Std.

  • How can I draw a hollow rectangle using CreatePen?

    - by LarsTech
    Since using the DrawArc function in GDI+ isn't very accurate when drawing a small rounded rectangle, I am using RoundRect instead. Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs) Dim hDC As IntPtr = e.Graphics.GetHdc Dim rc As New Rectangle(10, 10, 64, 24) Dim hPen As IntPtr = Win32.CreatePen(Win32.PenStyle.PS_SOLID, 0, _ ColorTranslator.ToWin32(Color.Green)) Dim hOldPen As IntPtr = Win32.SelectObject(hDC, hPen) Call Win32.RoundRect(hDC, rc.Left, rc.Top, rc.Right, rc.Bottom, 10, 10) Win32.SelectObject(hDC, hOldPen) Win32.DeleteObject(hPen) e.Graphics.ReleaseHdc(hDC) MyBase.OnPaint(e) End Sub This will draw a nice rounded rectangle, but it will also fill it with a white brush, erasing what I don't want to have erased. How can I draw this without erasing the inside of the rectangle?

  • How can I tell if a SQL Server database is being backed up

    - by Guy
    Is there a way to programmatically determine if a SQL Server backup is currently being performd on a particular database? We have automated database backup scripts for both data and log files, where the databases are backed up nightly and log files are backed up every 15 minutes, 24 hours a day. However, we think that the log file backup job is failing if it runs the same time as the full backup is being run. What I'd like to do is to make a change to my transaction log script to not run a transaction log backup while the full backup is being run. If there a DMV or a system table that I can query and work this out?

I don't want to use unsafe code (e.g. pointers) Any of my tries resulted in unreadable strings.

  • updating a shape in scene with a for loop using javafx

    - by Susanta
    Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change. Now since I am changing the width randomly I should see large number of changes. It seems I am making a wrong assumption on something basic. The code goes below: 7 var rec: Rectangle = Rectangle { 8 x: 10, y: 10 9 width: 140, height: 90 10 fill: Color.BLACK 11 } 12 13 Stage { 14 title: "MyApp" 15 scene: Scene { 16 width: 200 17 height: 200 18 content: [ 19 rec, 20 Button { 21 text: "Button" 22 action: function () { 23 for (i in [1..999]) { 24 rec.width = 25 + java.lang.Math.random()*50; 25 } 26 } 27 } 28 ] 29 } 30 }

  • Wrapping 3 objects or less inside a while / foreach in PHP

    - by DarkGhostHunter
    Simple question. I have an array of 21 elements, and show every three of them inside a <div> block. The code is something like this: <?php $faces= array( 1 => 'happy', 2 => 'sad', (sic) 21 => 'angry' ); $i = 1; foreach ($faces as $face) { echo $face; $i++; } ?> The problem lies when this array doesn't have 21 elements, sometimes it gets 24, an other times 17. How I wrap every three of them, and wrap alone the rest? I came up with using switch and case, but that works only when there are 21 elements only. I think I could count them beforehand and put a closing in the last one (even if it is a group of one element).

  • Behaviour of System.Timer when Interval property changed

    - by lowlyintern
    I have a System.Timer setup to trigger an event every day at 2AM. If the process the timer starts fails then I want the timer to be reset to run every 15 minutes until the process completes succesfully. // this is how the timer is set up. // this is working correctly. double startTime = milliseconds_of_hour_to_start. Timer = new System.Timers.Timer( startTime); Here is the code to reset the timer on success or failure of the event handler. NOTE the timer is not being stopped, just the Interval property is being reset. if (ProcessSuccess) { Timer.Interval = TimeSpan.FromHours(24).TotalMilliseconds; } else { Timer.Interval = TimeSpan.FromMinutes(15).TotalMilliseconds; } My question is this, if the process fails say 4 times, then succeeds will the Timer now be running at around 3AM? i.e. after failing will the original start time of 2AM be advanced by 15 minutes?
