How to take a snapshot with Ozeski SDK USB Camera?

How to take a snapshot with Ozeski SDK USB Camera? - c#

I'm quite newbie in programming, but triyng to run my first app in VS2019, C# .NET. I want to take a snapshop from my USB microscope. I've found OZEKI SDK library and I'm able to connect and view image from microscope. Ozeki has a tutorial on youtube:
https://www.youtube.com/watch?v=xjMAfMAix9c
and their website,
https://www.camera-sdk.com/p_6553-how-to-take-a-picture-snapshot-and-save-it-as-.jpg-in-c-.html
but when I tried to run app, I got message:
" images.save(curentpath)" object does not contain a definition for 'save' and no accesible...."
Code:
using System;
using System.Drawing;
using System.Windows.Forms;
using Ozeki.Media;
using Ozeki.Camera;

Thanks in advance for any help.

OK, I did it. Change:
var snapShotImage = _snapshotHandler.TakeSnapshot().ToImage();
to
var snapShotImage = _snapShot.TakeSnapshot().ToImage() as System.Drawing.Image;

DevExpress Winforms: why aren't my newly added Labelcontrols showing up?

I've inherited this project that someone started on a while back. It's made with DevExpress for Winforms. He already had a "welcome" page ready, with the "welkom" label and the "ik heb een afspraak" label (top of the 3 bottom ones). I've just started working on it today and can't seem to find out why my newly added Labelcontrols (the 2 bottom ones) aren't showing up when I launch the program/winforms.
Here's an image of how the designer looks:
Here's the Designer code page (Designer.cs file):

I'm not familiar with DevExpress so maybe I'm forgetting something somewhere?

I believe that you did not forget anything, because new labels already visible in the designer. There must be a very simple key to this riddle.
Comment out this line in the Welcome_Load method:
_controller.LoadLayout(layoutCtrlMain, Enums.LayoutType.Welcome);
If this helps, then newly added labels are not shown because the previously saved layout do not contain them.
To fix this problem and keep the _controller.LoadLayout code line uncommented, find the file where your _controller saves the layout and delete it.

Why does Visual Studio 2017 keep changing my public static statements to "public" after I change any aspect of any object on a form in C#

I've posted my code. Every single time I change anything on my this form in my Windows Forms App in C#, it changes my "public static" changes at the end to just "public" and then it adds "this." to every single reference to them. My code seems to run fine after I edit it again, but this is really annoying. I just wanted to make sure I'm not missing something or taking a poor approach to this.
The reason I am using public static statements is because I am modifying some Textboxes and a DataGridView object on my main form from other forms - i.e. looking up customer info from a database in one form and then entering the data on the main form to write up an order, and taking shopping cart information from a WebBrowser control on one form and putting it into a DataGridView object on another form. If this isn't how to accomplish populating forms from another form please tell me how and be as specific as possible as I am quite new to C#. Sorry if I've posted too much code - this is almost everything from my form1.cs file and I didn't know what (if anything) that I have here is causing the problem. The relevant "public static" statements are at the end.
(AFTER I WROTE THIS - I looked up another thread where someone said that forms are supposed to be a "specific instantiation" and that is why the developer environment keeps taking out the "static"). That being the case... HELP!! I do not understand how to change the values on one form from another form and I absolutely need to do so. - this code works, but I guess it's bad practice? - Completely lost and need very specific instructions to make this work)
Thanks in advance!!!

If you look into the .designer.cs file carefully you will notice this little comment
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
Basically that part of the code are auto generated by the designer and should never be modified manually.
And yes this is considered bad practice. Firstly the control should be self contained inside the form instead of being a static one. Static just means there will only be one instance across all the forms of the same class.
Direct modification of UI from one form to another is considered anti-pattern as well. You should be making a Data model and have the UI reads the updated data when they are changed. I know this might be a bit challenging for beginners as well for winform.
So if you want to take the shortcut you can expose a public property on the other form and by modifying the property your other form will update the appropriate control.
Edit:
In the other form's code behind (.cs file)
you can do like
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public string SelectedUser { get; private set; }
}
and then in your main form you would listen to the close event
Form1 other = new Form1();
other.FormClosed += Other_FormClosed;
other.Show();
...
private void Other_FormClosed(object sender, FormClosedEventArgs e)
{
Form1 other = (Form1)sender;
string selectedUser = other.SelectedUser;
//do something
}

C# login system

Currently I'm experimenting how I can make a login system, with different userinput. (Every user has his own information).I've two database tables, one is called "user" (here is id primary key, and username and password are in it) and the second table is the "userInformation" (here is id the foreign key and there is information like name,adres etc.) I've made it like this:
public partial class standardUserInterface : Form
{
int userIdNumber;
string[] userinfo;
public standardUserInterface(int userIdNumber)
{
InitializeComponent();
userinfo = new string[3];
this.userIdNumber = userIdNumber;
string selectUserData = "select voornaam,achternaam,woonplaats from dbo.usersinfo inner join dbo.loginuser on usersinfo.id=#loginUserId";
SqlConnection conn = sqlConn.openSqlConnection();
conn.Open();
SqlCommand comm = new SqlCommand(selectUserData, conn);
comm.Parameters.AddWithValue("#loginUserId", userIdNumber);
SqlDataReader dr = comm.ExecuteReader();
while (dr.Read())
{
for (int i = 0; i < 3; i++)
{
userinfo[i] = dr.GetString(i);
}
}
lblVoornaam.Text = userinfo[0];
lblAchternaam.Text = userinfo[1];
lblAdres.Text = userinfo[2];
}
}
What do you think about this? Is there a better way, or is this done right?
EDIT
This is the login before it's receiving the userdata
private string password;
private string username;
private int userIdNumber;
public Form1()
{
InitializeComponent();
}
private void btnLogin_Click(object sender, EventArgs e)
{
username = txtUsername.Text;
password = txtPassword.Text;
userLogin user = new userLogin(username, password);
//wachtwoord & gebruikersnaam controleren
if (username != "" & password != "")
{
if (user.checkPassword())
{
this.Hide();
userIdNumber = user.checkID();
standardUserInterface openUserInterface = new standardUserInterface(userIdNumber);
openUserInterface.ShowDialog();
}
else
{
MessageBox.Show("wachtwoord is onjuist");
}
}
else
{
MessageBox.Show("vul alle velden in");
}
}

Don't we need a authentication system for log in, wherein we can validate the used id and password? only if the validation is successful we will go for fetching the user details
one suggestion, it will be better if we can create a stored procedure for getting the user data instead of the inline query.

I've done it now (the stored procedure)`
SqlCommand comm = new SqlCommand("searchForUserInformation", conn);
comm.CommandType = CommandType.StoredProcedure;
comm.Parameters.AddWithValue("#loginUserId", userIdNumber);`

Panel visibility not changing in C# visual studio 2010

I'm trying to do something that i would think to be rather simple. I have 2 toolstrip items.
test1: ToolStripMenuItem which should show panel -> test_panel_1
test2: ToolStripMenuItem which should show panel -> panel1
test_panel_1 contains button -> panel_1_button1 which should hide test_panel_1 and show test_panel_2
panel1 contains button -> button1 which should hide test_panel2 and then show panel2
However, when I run the code and click on test1ToolStripMenuItem it shows test_panel_1 like it's supposed to, then when i click on panel_1_button_1 it just clears test_panel_1 and doesn't show test_panel_2. And regardless of what I click first, test2ToolStripMenuItem doesn't show panel1 at all.
Here's my code...
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace panel_test
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void panel_1_button1_Click(object sender, EventArgs e)
{
test_panel2.Visible = true;
test_panel_1.Visible = false;
}
private void test1ToolStripMenuItem_Click(object sender, EventArgs e)
{
test_panel_1.Visible = true;
panel1.Visible = false;
}
private void button1_click(object sender, EventArgs e)
{
test_panel_1.Visible = false;
test_panel2.Visible = true;
}
private void test2ToolStripMenuItem_Click(object sender, EventArgs e)
{
test_panel2.Visible = false;
panel1.Visible = true;
}
private void button1_Click_1(object sender, EventArgs e)
{
this.panel1.Visible = false;
this.panel2.Visible = true;
}
}
}
and, not sure if this helps, but...

I've toyed with Usercontrols a little, and i like the way i can edit and view them much better than panels; however, i don't know how to control hiding and showing them.
Thanks for the help. I know this must be coding 101, but it's something i haven't quite fully figured out yet.

It looks like your test_panel_2 is a child of test_panel_1. panel1 is a child of panel2. This is likely not what you intended. What's happening is that, because test_panel_2 is inside test_panel_1, hiding test_panel_1 also hides test_panel_2. There's a hierarchy there.
There's one or two spots where you set the visibility to false again - I'm not sure if those are correct.

Creating an Inputbox in C# using forms

Hello I'm currently creating an application which has the need to add server IP addresses to it, as there is no InputBox function in C# I'm trying to complete this using forms, but am very new to the language so not 100% as to what I should do.
At the moment I have my main form and a form which will act as my inputbox which wants to hide on load. Then when the user clicks on the add IP Address on the main form I wish to open up the secondary form and return the IP address entered into a text box on the secondary form.
So how would I go about doing this? Or is there any better ways to achieve similar results?

In your main form, add an event handler for the event Click of button Add Ip Address. In the event handler, do something similar as the code below:
private string m_ipAddress;
private void OnAddIPAddressClicked(object sender, EventArgs e)
{
using(SetIPAddressForm form = new SetIPAddressForm())
{
if (form.ShowDialog() == DialogResult.OK)
{
//Create a property in SetIPAddressForm to return the input of user.
m_ipAddress = form.IPAddress;
}
}
}
Edit: Add another example to fit with manemawanna comment.
private void btnAddServer_Click(object sender, EventArgs e)
{
string ipAdd;
using(Input form = new Input())
{
if (form.ShowDialog() == DialogResult.OK)
{
//Create a property in SetIPAddressForm to return the input of user.
ipAdd = form.IPAddress;
}
}
}
In your Input form, add a property:
public class Input : Form
{
public string IPAddress
{
get { return txtInput.Text; }
}
private void btnInput_Click(object sender, EventArgs e)
{
//Do some validation for the text in txtInput to be sure the ip is well-formated.
if(ip_well_formated)
{
this.DialogResult = DialogResult.OK;
this.Close();
}
}
}

You could just use the VB InputBox...
Add reference to Microsoft.VisualBasic
string result = Microsoft.VisualBasic.Interaction.InputBox("Title","text", "", 10, 20);

I've needed this feature, too. Here's my code; it auto-centers and sizes to fit the prompt. The public method creates a dialog and returns the user's input, or null if they cancel.

Add a button in main form.
Create a form with textbox for ip address. (lets say it IPAddressForm)
Add click event handler for that button.
In the event handler, create an instance of IPAddressForm and call showdialog method of IPAddressForm.
Store the ip address in some class variable.
If the showdialog result is ok, read the class variable from main form (simplest way is to declare the field as public)

Looks like Francis has the correct idea which is what I would have suggested. However, just to add to this I would probably suggest using a MaskedTextBox instead of a basic TextBox and add the IP Address format as the Mask.

You can create your special messagebox. I created my messagebox for getting database information like below. And when the messagebox open, application stop during you click any button in related messagebox.
