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?
View 4 RepliesI 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.
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'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 new to programming . My task is to change the background of the app so that every time I open the app I get a different background image and every minute the background image changes. I am a complete noob and I am trying to do this for almost 36 hours now. I am getting really depressed right now. Every time I am trying to write a code, there's an error.

Place an Image on top of a Button. Move both when the Button is pushed.
Please have a look at this code:
#include <GUI.h>
using namespace Graph_lib;
//------------------------------------------------
class rotation : public Window {
public:
rotation(Point xy, int w, int h, const string& title):
Window(xy,w,h,title),
[Code] ....
The problem is that, it is not possible to define an Image in public/private part of the class rotation. Image needs all arguments to be supplied even when declaring one. (Image is here in Graph.h)
And if I define that Image in the body of main() function, so how to provide access for void rotate() to change its position with the position of button simultaneously.
My goal is to have couple of items in the listbox and when highlighting one item a image in the picturebox should appear, and so on for each item in the listbox.I just don't know how to change image depending on selected item in the listbox instantly.Also when i highlight item a text in label should be like in highlighted item in listbox.

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'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 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.

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?
View 1 Replies View RelatedIm trying to compare the image of a button to another image in Visual Studio like so...
//variables

Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)
My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code:
#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;
void change(double cents, int a[]);
int main() {
double Dollars;
double cents;

I have been learning C# so I've been dragging and dropping. I have a "First Name" and "Last Name" text field. I want to add this to a combo box called something like "User List", which will list the last named then the first names. However I figure I can work with something that can get me to store the names in the combo box.
So. I have two things I need to know:
What do I have to do to have when the button is pressed, add to the combo box?
Is there a way to retain all the entries I have entered? Or no?
I'm trying to find an event for the combobox when its selected value changes , but I can't seem to find the right one since I've tried several events in the dataGridView that are just triggering at the wrong moments. I need to remove the selected item from that combobox so that it doesn't get selected again at the second combobox which usually have the same items .
View 5 Replies View RelatedI'm having issues with selecting the next item in sequence in a combobox dropdown. The dropdown consists of letters A-Z and there is a timer that I have running to change the letter every x minutes. What I need to do is if, for example, letter A is selected, when the timer goes off, it will change to letter B, etc. If it's at letter Z, it needs to go back to the first item, letter A.
letterCode.SelectedIndex = letterCode.SelectedIndex + 1;
if (letterCode.SelectedIndex >= 26)
{
letterCode.SelectedIndex += 0;
}
I have the above, but I keep getting an error:
InvalidArgument=Value of '26' is not valid for 'SelectedIndex'.
how to get this working (letter changing logic block).
I have a comboBox that I created in XAML using using binding and I'm unable to get the selection. I've tried everything I could think of or find on, but no luck.
Here's the relevant XAML and C# code for the comboBox:
<ComboBox Name="projSelected" Selectionchanged="projSelected_Selectionchanged" HorizontalAlignment="Left" Margin="424,27,0,0" VerticalAlignment="Top" Width="199" DisplayMemberPath="proj"/>
projSelected.ItemsSource = DAL.projectList;
Then here is where I try to check the selected value:
private void projSelected_Selectionchanged(object sender, SelectionchangedEventArgs e) {
projectDataList.ItemsSource = null;
projectDataList.Items.Clear();
[Code] ....
And here is my output in the MessageBox that I'm using to test the code:
Quote

So I'm working on program I had in Windows Form Application.
I have a combobox that lists the years 1981-2013. Beside it, a simple Enter button.
I wanted to be able to assign individual lines of text to each year that would be displayed in the message box.
Like if the user selects 1981, clicks Enter and the message box displayed "In the year of 1981.." but if they select 1982, the message box displayed "In the year of 1982.." I have everything else I want working, except that I can't figure out how to assign different lines of text to different years.
I have a data-bound ComboBox and I populate a DataSet with the values returned from a SQL query.
public DataSet CompanyArray(DataSet dataSet) {
SqlConnection connection = InstancesTest.IDataInterface.DefineConnection();
SqlCommand command = new SqlCommand();
command.CommandText = "usp_CompanyArray";
command.CommandTimeout = 20000;
[code]....
All this works fine. The reason I populated it in an array was so that I could sort the items alphabetically. I know I could just do an "order by" in SQL but I chose this route.
What I'm after is putting a "Please Select" at index 0 in the ComboBox. How can I move this value to the top of the list, without reordering the sorted list?And I don't really want to insert a "Please Select" as a first row in a database table.
I have a combobox which doesn't have the CBS_SORT style and after adding some items I'd like to offer the ability for the user to sort it alphabetically by clicking on a given button. How can I sort the combobx after it has been created and some items added to it ?
