c - Using two textures in OpenGL -


I am writing a program in which I have to use two different textures. I can read a file and use it as a texture, but by now I'm unable to get two textures to work. I have my code to set a texture which I have: 

  FILE * fd; Int k, nm; Four c; Int i, i; Four b [256]; Float S; Int red, green, blue; FD = FOPAN ("AILAPPPM", "R"); Check the first line for // p3 fscanf (fd, "% [^ \ n]", b); if (b [0]! = 'P' || b [1]! = '3') {printf ("% s is not a PPM file \ n", b); System ("pause"); Exit (0); } // leave comments fscanf (fd, "% c% c", & amp; c, & c); While (C == '#') {fscanf (fd, "% [^ \ n]", b); FSACNF (FD, "% C% C", and C, and C); } // First put the first character of the non comment line ungetc (C, FD); // file file information fscanf (fd, "% d% d% d", & amp; o, & amp; m; & amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; Nm = o * m; // Image of the overall size = mallok (3 * size (glutton) * nm); S = 255./k; For (i = 0; i & lt; nm; i ++) {fscanf (FD, "% d% d% d", & red, and green, and blue); Image [3 * nm - 3 * i - 3] = Red; Image [3 * nm - 3 * i-2] = green; Image [3 * nm - 3 * i - 1] = blue; } GlPixelTransferf (GL_RED_SCALE, S); Glupecs Transfurf (GL_Green_SCAL, S); Glupecs Transfife (GL_ BLUE_SCALE, S); Glupeclasty (GL_UNPAPIPPHGHH, GLTRU); Glaxics Story (GL_UNPAP_IMENTMENT, 1); glEnable (GL_TEXTURE_2D); GlTexImage2D (GL_TEXTURE_2D, 0, 3, o1, M1, 0, GL_RGB, GL_ UNSIGNED_INT, image); GlTexParameterf (GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP); glTexParameterf (GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP); glTexParameterf (GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); GlTexParameterf (GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); Glennable (GL_DEPTH_TEST); Glucaller (0.0, 0.0, 0.0, 1.0);   
 I have tried to fix everything that I can think and can not work properly.   
 
 
 Your texture details look fine, but you have to brush on the basics of OpenGL. The red book is a good place to start.  
  
 Go to the bottom of the section on the  Texture Object .  
 Before calling  glTexImage2d , you want to generate and bind a new textured object.  
 When rendering, you compose the texture that you want to render before making any preferences.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

I am using JPA 2.0 and getting the following code in the DAO layer: Public Zero Test () {string key = "status"; String [] Conditions = {"A", "B"}; & Lt; TestTable & gt; Results = Search (Keys, Conditions); } Public listing & lt; TestTable & gt; Search (string key, object value error) {string sql = "test ndf to testlet and jade nand." + Key + "in:" + key; TypedQuery & LT; TestTable & gt; Query = entityManager.createQuery (SQL, TestTable.class); Query.setParameter (key, Arrays.asList (valueArr)) / *** Error Line *** Return query.getResultList (); } In the above error line, it throws the following exception: java.lang.IllegalArgumentException: parameter value element [[Ljava.lang.String; @ cbe5bc] did not match the expected type [java.lang.String] Why is this expected type string while actually this string []? Please help! Note: This is derived from the normal routine and is a simplified code. I can no...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
