I have a picture box, inside a table layout panel. The default size for the picture box is 456, 457. However, what I want to do is have the picture box be the size of the available area, even if the form is full screen.
I have the picture box dock set to fill etc. but not matter what I do, it refuses to change the dimensions from the ones above.
The only work around I could find that worked was this:
this.pbMainMap.Size = new Size(Screen.GetWorkingArea(this).Width, Screen.GetWorkingArea(this).Height);
Which is pretty useless if you are using a table layout panel. Can I grab the dimensions from the cell I am in or something?
I'm currently reading/programming from "Head first C#" book. I have this project which is making a program that has four dogs which race and there are three players that can bet on the race. I need to learn how to make the "dogs" (picture boxes) move from left end to the right end of a picture box.
Here is the code:
using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; using System.Drawing;
I am working with windows mobile 6.5 and sql compact, trying to create application to save pic on database but when i try to save pic that loaded to picturebox it giving this error "could not find file 'picturebox" and in windows mobile we don't have imagelocation property and this is code that i use it
using System; using System.Linq; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing;
I Was Try To Change PictureBox To The Memory Stream And Then I Read Memory Stream Bytes And I Send Over The Netwrok Here Is Code
MemoryStream ms = new MemoryStream(); pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); // we save the image in side the Memory strem byte[] pic_array = new byte[ms.Length]; ms.Position = 0; ms.Read(pic_array, 0, pic_array.Length); //
[Code]...
but when i want get the Data o mean Bytes from Network tream How can i save in memory stream then dispaly in the picture box ? i try some thing but it is gave me error !
Socket handlerSocket = (Socket)alSockets[alSockets.Count - 1]; NetworkStream networkStream = new NetworkStream(handlerSocket); int thisRead = 0; int blockSize = 1024;
I've been working on making a sprite generator and this is one thing that has kept giving me difficulties. No matter what I've looked up nothing directly says how to nor can I find anything on a similar topic to try and apply to it either. I know how to add the resources and names for the options but how do I get the options to make my picturebox image change in relation to the selection?
I've been looking for a C# library that is well documented and can show DICOM (medical CT scan data, including the image) as jpeg/bmp data that is viewable in a PictureBox.
I've only found OpenDicom which is more or less unsupported now and EvilDicom - whose owner has made some significant changes to it, making all existing stack overflow questions on it irrelevant.
I am creating an employee details project, the image is getting stored in the database but i am not able display it in the picture box.
private void button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(Connectionstring); con.Open(); SqlCommand cmd = new SqlCommand("select photo from emprecordtable where eid='"+comboBox1.Text+"'", con); //SqlDataAdapter da = new SqlDataAdapter(cmd); //DataSet ds = new DataSet();
[code] ....
In sql server i have table called emprecordtable and i have the fields eid, rfid, empname, designation, phno, addres, and photo which is the image field and i have given the datatype as image but in the database the image is getting stored as Binary Data.. So, how to display in the picturebox from the database.
I am trying to build a WinForm application that will allow you to load an image into a picturebox and then draw multiple rectangles (empty or translucent) to kind of highlight areas. I want all the rectangles to stay on the image (i can take care of a clear method later). The code below has the latest two attempts I've tried. One is all commented out and the other is not. Both will load the image just fine but neither will allow me to draw/select rectangles on the image.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Drawing.Drawing2D; using System.Linq;
What i'm trying to do is load an image from my database create some graphics to it. probably just some lines and marks and save it back to my database. here's so far what I got.
for creating graphics: } private void pictureBox3_MouseDown(object sender, MouseEventArgs e) { draw = true; } private void pictureBox3_MouseMove(object sender, MouseEventArgs e) { if (draw) { Graphics g = Graphics.FromImage(pictureBox3.Image);
[Code] ....
but the saving part doesnt work :( I think it only saves the image loaded to the picturebox but not the graphics created to it. how to merge it? i've tried to google it and found some sort of same cases but fails to make it work, something like converting it to bitmap.
I have a form with a picturebox and some buttons to move the picturebox. I don't want the user to guide the picturebox out of the form even by dragging the form border picturebox moves just in the form border, and also there is a button to guide the picturebox to the start position (start choose by user). What can i do?
comparing with screen size the height is bigger but lenght is smaller. I don't understand.
I can understand that different printers process the fonts in different way and then to have different lenghts. That's not the problem. The problem is I need to simulate in screen the same behaviour i will have on printer because these texts are being aligned in the document, and I don't want to see that the text si aligned different in text than in paper.
What can I do to render the text on screen with the same size I will have on the printer? Print preview is doing it. Should I change the font parameters? is something related with pixels per inch?
I'm writing a sorted vector implementation and trying to do it as simply as possible.
Right now, I'm declaring the sorted vector with a protected subclass of vector, then using the "using" keyword to explicitly inherit all methods that aren't related to adding new elements to the vector (so I can control the order).
Eg:
Code: template<typename T, class Cmp = std::less<T>> class sorted_vector : protected std::vector<T>{ public: typedef typename std::vector<T>::iterator; using std::vector<T>::operator=; using std::vector<T>::assign; using std::vector<T>::get_allocator; using std::vector<T>::at; using std::vector<T>::operator[]; //... };
Obviously, this is annoyingly redundant. So what I'd like to do is something using the new "delete" keyword from C++11. Is there any quick, expressive way of deleting specific methods?
Also, it's pretty annoying to have to typedef base_class::type type to inherit a type from a base class. Is there a shorter way to do that?
I've created a modeless dialog from my main dialog as follows:
Code: m_pContainerDlg = new CDlgContainer(NULL, this); m_pContainerDlg->Create(CDlgContainer::IDD, GetDesktopWindow()); m_pContainerDlg ->ShowWindow(SW_SHOW);
This container dialog creates a child dialog which I show inside the container
Code: BOOL CDlgContainer::OnInitDialog(){ // Create the child dialog and show it m_pChildDlg = new CChildDlg(this); m_pChildDlg->Create(IDD_DIRECTORY_DIALOG, this); return FALSE; }
From my child dialog I then create a modal dialog when a user clicks on a button
I was wondering why, in C, the sizeof of a struct is larger than the the sum of all the sizeofs of it's members. It only seems to be by a few bytes, but as a bit of a perfectionist I fine this a bit annoying.
Below is simplified code consists of two classes, namely Parent and Child.
Child is inherited from Parent.
All member functions of class Parent are declared virtual, and they have been overridden in the class Child.
Code 1:
#include <cstdlib> #include <iostream> using namespace std; #define QUANTITY 5 class Parent {
[Code] ....
The output of the code:
Child::showID() -- ID is 1804289383 Child::showID() -- ID is 846930886 Child::showID() -- ID is 1681692777 Child::showID() -- ID is 1714636915 Child::showID() -- ID is 1957747793
Parent::operator=() invoked.
Child::showID() -- ID is 1804289383 Child::showID() -- ID is 846930886 Child::showID() -- ID is 1714636915 Child::showID() -- ID is 1714636915 Child::showID() -- ID is 1957747793
Question:
Why is Parent::operator= invoked instead of Child::operator= ..?
Isn't it already declared virtual and hence would be overridden..?
I need to invoke Child::operator= instead. How to achieve this?
I have a class that extends another class, and I want multiple constructors in the child class, but the child constructor needs to call the parent constructor. This is what I have
ChildClass child1; // do stuff with child1 // breaks ChildClass child2(1); // do stuff with child2 // works fine
Using the default constructor breaks my program at runtime, but using the one with a parameter works fine. The default constructor calls the other with the same thing as the main part in the program, so I would think this should make no difference, but obviously that isn't the case.
I have an array of bone parent indices (as intgers), where root bone is tagged as -1, bone can have only one parent. At some point i need to traverse thru all children of some arbitrary bone (leaving others untouched) but this seems tough to do with this setup.
I cannot come up with algorithm to create linked list like hierarchy from this , with old DX9 API in their animation system we have structure like this:
struct D3DXFRAME { // bone ... // some irrelevant data members D3DXFRAME* pFrameSibling; D3DXFRAME* pFrameFirstChild; };
Where I can simply use recursion to achieve what I want.
I want parent and child processes to communicate in C linux using pipes. I have created two file descriptors. one for parent to child i.e. readpipe and other writepipe for viceversa. But I am getting null as output for ch and ch1 strings in my code below.
#include <stdio.h> #include<stdlib.h> #include #include<unistd.h> int main(){ pid_t pid;
I'm using windows forms and I have a parent dialog box that consists of a text box and a drop-down that launches a child dialog box. The child takes user input and then prints dialog to the text box in the parent. However, the output does not appear in the text box until I close the child.
Now my question is, how do I get the text to appear without closing the child? I hit a button to send the info to the text box, but it still doesn't appear until the child closes. I also need to set up a button to suspend the child so that the user can click/copy/etc the parent.
I am doing C++ data structures exercises, and I am still learning some of the more basic concepts. I have a parent class:
template<class T> class linkedListType { public: protected: int count; nodeType<T> *first; nodeType<T> *last; private: };
Derived class:
#include "linkedListType.h" template<class T> class orderedLinkedList: public linkedListType<T> { public: void mergeList(orderedLinkedList<T> &list1, orderedLinkedList<t> &list2) { first = list1.first; ... } private: };
There is more code in my mergeList() function, but I included the line that is giving me problems. The error that my CodeBlocks compiler is giving me is that 'first' was not declared in this scope.
Strangely enough, if I change it to this->first, the error disappears.
1. Why does it not recognise 'first'? 2. Why would this->first work at all? Is the 'this' object a smart pointer?
