Is there any way to allow user to resize a CDialog only in one direction ? I mean, by width, but not by height ? How ? I noticed that overriding WM_SIZE, I can do nothing about this issue ...
I have a Dialog with a Browser Control and load a Site with a Video, as the Title says, is there any Way to keep a Dialog in the Format of 16:9 Format, in eg. if someone change the Width or Height of a Dialog, the Height/Width should be changed to? To keep this Format permanent?
My first try was in a OnSizing(UINT fwSide, LPRECT pRect) Function but this is not the best way, because any Time i want to resize my Dialog it flickers terribly and i know i make it in a wrong way.
I have a very similar dialog called IDD_SETTINGS2_DIALOG with all the exact same variables. Is it possible to conditionally load either of those dialogs in that class through a variable pass into the constructor? If so, how do I edit that enum type to add both?
Nothing complicated, and it works well ... except one thing: when I press the shift key and the mouse is moving by SetCursorPos, is moving pretty slow ... why ? I can not figure out why ! For testing, I attached the test project ...
I am currently working on problem set 4 for Harvard's online CS50 course. I am working on a program that resizes a bmp image by a factor of N. N in entered along with an in-file and out-file in a command line argument. The program needs to calculate the header file for the out-file and write it to the out-file. It then needs to actually resize the image and, again, write to the out-file.
The first question I have relates to the header file, here is my code for calculating the header file:
At this point I need to actually resize the image. As far as I can tell there are 2 ways to go about this you either have to use an array to store each line you want to print repeatedly (and then you can just write it repeatedly) OR you have to move the pointer back in the input stream and repeat the read/resize/write process each time you need to print the row.
It is this that I am stuck on, first of all, I am not sure what system would be better for resizing the image, although I am leaning towards using an array, and regardless, I don't even know where to begin when in implementing either.
So what I am asking for is, first of all, just a "double check" to make sure my header code makes sense. And second of all, a push in the right direction for actually resizing the image. Here is my complete code:
/**************************************************************************** * resize.c * * Resizes a BMP piece by piece, just because. ***************************************************************************/
#include #include #include "bmp.h" int main(int argc, char* argv[]) { // ensure proper usage if (argc != 4) { printf("Usage: copy N infile outfile
Below, is the program I completed so far. I need to write a C program that reads in a stream of integer values, each representing an (x,y) pair on the cartesian plane. It then says I need to display the distance and direction from one point to the next. I tested it out, and it works.I need to use a conditional statement, and I'm a little confused how to display the direction(right, left, up, or down).I think I need to use an. "If" statement with my first one being something like:
If (y2 = y1) && (x2 > x1)
and I'm not sure what else to put,or if this is wrong. And with y staying the same and x increasing, the direction would be right.
Code: #include <stdio.h> #include <stdlib.h> #include <math.h> int main(void) { int x1, y1,x2,y2,x3, y3,x4,y4,x5,y5,x6,y6; //x and y coordinates
i new to c++ programming. i have a program due soon in vector addition. i am to design should be able to add vectors with certain magnitude and direction and give its resultant magnitude and direction (i know how to do this mathematically but programming is not working. the user should be able to select how many vector he/she wants (i don't know how to do this, so i added 3 vectors). here's my work - i did this purely algebraically. it's still incomplete but it compiles. my "if else" statement also doesn't respond correctly.
#include <iostream> #include <string> #include <vector> #define PI 3.14159 #include <math.h> std::vector<int> v; // declares a vector of integers using namespace std;
implementing an algebra function.(a+b)(a-b).does c++ support this sort of function.Did a quick search on google and all of them suggested using libraries like boost. is there anyway to do this without a library?
It is technically not a programming question and is more maths oriented. It has to do with game AI and specifically getting the AI to rotate correctly. I am trying to create the base method that handles AI rotation. It will take a target orientation and rotate the entity from it's current orientation to that target orientation.
Let's say we have a Entity that has the orientation of 1.57079 Radians (90 Degrees) and we want to change that Entity's orientation to 0 Radians (0 Degrees). How would one find the correct way to rotate from just them two orientations (IE find the shortest rotation direction from a current orientation to a target orientation)?
As my implementation stands now the Entity rotates just fine I think but always in a clockwise rotation (Because I can't figure out how to determine the best rotation direction). For example using the previous number (1.57079 Radians to 0 Radians) the Entity will rotate all the way around 270 Degrees clockwise instead of rotating just 90 degrees counter-clockwise.
I have thought about possibly projecting vectors a short distance forward from the current orientation and target orientation to figure out the rotation direction but not sure if that is a good way to implement it.
So I need to make a program that prints a triangle of symbols in a certain direction.
For example: Code: How many rows? 3
@ @@@ @@@@@
How to do that. It's rare that I post without figuring anything out, but I'm just simply not sure. I have a program that prints a triangle in a similar direction, so maybe if I could get some hints as to what to do with that (HINTS, not direct source code) .
Code: #include <iostream> #include <iomanip> using namespace std; int main ( ) {
I am trying to re-size a bitmap image for a class.They gave us two options to use to do the program with: an array or move the file position indicator. I want to use the file option. All the bitmap header info is checking out. The file after being re-sized should be 822 bytes but it is 1.6 KiB and the image is distorted.
Code:
#include <stdint.h> /** * Common Data Types * * The data types in this section are essentially aliases for C/C++ * primitive data types.
I made a resize function for my dynamic array template class that goes as follows. Note that the private member variables are T* arr, unsigned used, and unsigned cap.
template <class T> void darray<T>::resize(unsigned size) { if (size > cap) { T* temp_arr = new T[size];
[Code] ....
Whenever I use this function to increase the size of the array, it will work the first time I need to use it, but after that, Visual Studios will trigger a breakpoint at line 14, and if I continue past the breaks, I eventually get _CrtIsValidHeapPointer(pUserData) assertion failure.
When I use vectory.push_back(obj), if the length is out of reserved bound, it will deallocate the whole vector and reallocate a big piece of memory. From my understanding I think c++ only allocates 1 more place for the new obj. This is quite inefficient. Is there a way to set the step length whenever the size is out of bound? e.g. 50 more spaces.
When I try to resize my form, every time i try to resize it while running, the window blinks between original size and the new size it was given, when i release the mouse it either stay in its new size or shrinks back to its original size, What makes it return to its original size, maybe its something with the form_Resize function..
how can I create a GUI application that can resize also the control buttons. If the user decide to make the windows bigger or smaller I would like my textbox, buttons, etc.. to follow. Like in Java they use a layout manager, but I can't seem to find the answer for c#. I though to use table layout panel, but it doesn't expand when expanding the windows, unless i miss something
