View 3 RepliesI'm using VS 2012. Installed MYSQL 5.6, C++ Connector 1.1.3. Created a sample table using mysql. Now i like to create a connect between mysql and MFC dialog. Using this, i was try to connect.
Server Explorer -> Data Connection -> Add Connections ->MYSQL Database -> Addconnection
To get the connection, i want to enter the connection settings like:
server host name = localhost, user name =root, password=
If I pressed any letter in the keyboard means add connection dialog was closed automatically.
How to connect mysql(localhost) with MFC Dialog?
I am working on a MFC application that I used for Image Analysis. I have a FrameWnd called MillChart that I use to generate an Image. This window is displayed at the run time in the application and not a part of the GUI dialog. It automatically resizes according to the different monitor resolutions and because of this there is a lot of empty space to the right of the MillChart. I was planning to add a picture control in the GUI dialog and redirect whatever is displayed in the MillChart to the Picture Control so that I can place my other elements (checkboxes, scrollbars etc) that I use in my app close to this MillChart and also set the size of the MillChart to a constant size.
Here is the code for positioning the elements (Note: I have only shown the MillChart position)
Code:
void CMainFrame::PositionElements()
{
CRect r, r2, r3;
GetClientRect(&r);
int mcs = r.Height() - r2.Height();
mMillChart->MoveWindow(r.right - r2.Width(),r.top + r2.Height(),mcs,mcs);

I am trying to draw a shape or font on dialog and then fill the outline. I have 2 buttons on this 2 buttons I have the following code
Code:
case IDC_BUTTON1:
MessageBox(hDlg, L"Start Drawing!!", L"ButtonPressed", MB_OK | MB_ICONEXCLAMATION);
hDC = GetDC(hDlg);
brush = CreateSolidBrush(RGB(128, 128, 128));
SelectObject(hDC, brush);
[code].....
When I remove the BeginPath() and EndPath() functions my lines are being drawn. But when I insert this BeginPath() and EndPath() and StrokeAndFillPath(hDC); the nothing is being drawn.
Why it is not doing as per the expectations. I want to draw a shape for example A with a outline. And i want it to be closed when drawing is ended and filled the hollow portion.
What am I doing wrong in this ?I am not implementing it in WM_PAINT but drawing is done in WM_LBUTTONUP.

View 2 Replies View RelatedOkay so I have to draw a square using "c" that draws according to the user input. Also, this has to be a function, and here is the code I have so far:
#include <stdio.h>
void DrawSquare(int length, char symbol);
void DrawSquare(int length, char symbol) {
int row;
int col;
[Code] .....
When I run this program it compiles fine but when the user input is recorded it just draws nothing but makes tons of spaces.
How can I draw a sprite/graphic on the window of an third party application? E.g. I want to draw a graphic beneath each tab of Firefox for additional information. The position of the sprite needs to be relativ to the position of firefox, so if you move firefox, the sprite moves with it.
The solution needs to work on mac and pc. So I'll use a crossplatform framework like c++ boost or something.
Of course I can get the position and then just redraw it. But what's the best way to draw it?
Just found a tool which does what I need. Basically a HUD like this: [URL] .... The boxes with the numbers are what I need.
I am trying to use CDHtmlDialog in a MFC dialog based project.
What i want to achieve is pretty sample. Have one image, one button and one text box in the HTML page.
And then dynamically change this based on a timer. i.e., there're multiple images in the folder and it will change every seconds. Once the button is clicked, the timer stops and no more image changes. Same time when image changes the text in the text box also should change.
I know this is pretty simple, but for some reason i am not able to make the image even display in the dialog.

z = 40;

I will sketch the scenario I would like to get working below. I have one main application.
That application, based on user interactions, can load other applications in a secure shell. This means these child applications cannot interact with the OS anymore, nor with each other.
The parent program can at any time call functions of these child programs.
The child program can at any time call functions of these parent programs.
How to implement this in C++? Preferably both parent and child should be written in C++.
The performance of loading the child applications doesn't matter. The only thing that matters is the performance of the communication between child and parent.
i have to create a console based application in c language that can join and split bitmap images. the requirements of the application are as follows :
1. Split Image
Enter number of parts:
Enter source image path:
Enter destination folder:
2. Join Images (all images should be of same width and height)
Enter image path:
Join more Image (y/n):
3. Exit
Take care of following things:
- Application should show number of images processed while running.
- Acceptable Image format is BMP only.
- Application should give all the validations for correct image name, type, size, path, etc.
I am creating windows application in that i wan create dynamic controls so that i want to give line break after each control in panel.I had tried
panel1.Controls.Add(new LiteralControl("<BR>"));
but it gives error like : "The type or namespace name 'LiteralControl' could not be found (are you missing a using directive or an assembly reference?)" Also have tried adding namespace for leteral control bt it not accepting.VS10 automaticaly get restart if i trying to add system.web.dll
#include "stdafx.h"
#include "iostream"
#include "conio.h"
#include "windows.h"
using namespace std;
void main(){
HDC hdc = GetDC(NULL);
DWORD color = GetPixel(hdc, 500, 500);
[Code] ....
From this code I think it reads pixel from screenshot. I want to read from file. I think I have to change this line
HDC hdc = GetDC(NULL);
but I don't know how to?

With using SDL_Maprgb and SDL_GetRgb. I am new to programming.
void put_pixel32 (SDL_Surface *surf, int x, int y, Uint32 pixel){
Uint32 *pixels = (Uint32 *)surf->pixels;
pixels[(y * surf->w ) + x] = pixel;

how do i get use of this code?

I'm have a bitmap that's about 4000x2000. But I want to put it all into a picture control. I attempted to use stretchBlt() to shrink it. But it did not work.

I've just started using the CImg library and when I try to load a picture with this code:
CImg<unsigned char> image("example.bmp");
It works perfectly. But when I try to type in the image file name using the console it gives me errors. For example, if I try this:
std::string input_file;
std::cin >> input_file;
CImg<unsigned char> image(input_file);
It doesn't work. The way I see it, I should be able type "example.bmp" into input_file and use it but it doesn't work, and gives me the error:
"error: no matching function for call to 'cimg_library::CImg<unsigned char>::CImg(std::string&)"
I have included iostream and string.h.
Here's what i'm searching for: I have a form with 3 pictureBoxes (pictureBox1,2,3). The form also contains one button.
What I want is that when the user clicks the button (so button_click event) that the 3 pictureBoxes each show a different picture. And when I click the button again again 3 different pictures will load.
I already found out that I need to make an arraylist for the pictures (there are about 100 pictures). A System.Random
to select random images. But I have absolutely no clue on how to write this code.
I have a c# form that has two pictureboxes on it. I use two webcams I want the first webcam to allways show it's image in picturebox 1 and the second webcam to allways show it's image in picturebox 2.
How can I write this and stop that annoying popup dialog asking me to select a webcam each time it runs.

View 1 Replies View RelatedI was loaded a bitmap using this code. I'm using mousemove method to known the Dialog's mouse move position & get the RGB pixel.
I want to get the picture contol's mouse move position & using this point (x,y) i will get the particular color ref value R, G, & B.
My picture control size is 256 * 256 & I was loaded an image 512 * 512.
Using scroll bar, I was view the image but can't get the particular pixel in the picture control.
The below code get the Dialog's mouse move cursor position & RGB Values only.
Code:
void CMyDlg::OnMouseMove(UINT nFlags, CPoint point) {
int R,G,B;
COLORREF ref;
ref = m_dcMem.GetPixel(point.x,point.y);
R = GetRValue(ref);
G = GetGValue(ref);
B = GetBValue(ref);
CButton::OnMouseMove(nFlags, point);
}
How can i get the picture contol position even use the scroll bar.
I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?

Ok, this thing works as far as the getting the image and drawing the rectangle but for the life of me I cannot figure out why it is causing an in the program.cs.
public partial class Crop : Form {
public Crop(Image BaseImage) {
InitializeComponent();
if ((Bitmap)BaseImage != null) { pbOriginal.Image = BaseImage; }
[Code] ....
BaseImage is pulled in from the main form's picture box.
