Overview
I am trying to capture a screenshot of external application and load the image to a .NET PictureBox.
user32.dll Unmanaged Code
There are a bunch of examples using user32.dll an I am looking for a .NET answer that does not use the user32.dll file.
App #1
I have provided sample code below that I am using for demonstration purposes. When the program is executed, it parses Processes and saves ones with valid window titles to the drop-down list.
When you select the app name from the drop-down list and click the button, it will try to capture the screenshot app and load into the .NET PictureBox.

foreach (Process process in Process.GetProcesses())
{
if (string.IsNullOrEmpty(process.MainWindowTitle))
continue;
apps.Add(process.MainWindowTitle, process.MainWindowHandle);
comboBox1.Items.Add(process.MainWindowTitle);
}
}
private void button1_Click(object sender, EventArgs e)
{
IntPtr intptr = apps[comboBox1.Items[comboBox1.SelectedIndex].ToString()];
Graphics g = Graphics.FromHwnd(intptr);
// get width and height of app #2
int width = (int)g.VisibleClipBounds.Width;
int height = (int)g.VisibleClipBounds.Height;
Size s = new Size(width, height);
// create new bitmap
Bitmap wincapture = new Bitmap(width, height, g);
// code tried.
//g.CopyFromScreen(0, 0, 0, 0, new Size(width, height));
//g.DrawImage(wincapture, 0, 0, width, height);
// once App #2 has been captured, show image in picture box.
pictureBox1.Image = wincapture;
}
}

This is the code I came up with to take a screenshot of an application without using user32.dll.
To make the app active, and wait for 20 to make sure it has completed.
Microsoft.VisualBasic.Interaction.AppActivate(ProcessId);
Threading.Thread.Sleep(20);
To capture the active window, I used the following. Added a delay of 200, then convert the clipboard object to an image.
SendKeys.SendWait("%{PRTSC}");
Threading.Thread.Sleep(200);
IDataObject objData = Clipboard.GetDataObject();

So, I'm trying to create an accordion with dynamically loaded buttons. In the future, the title of the buttons will change depending on the details I've retrieved from somewhere. For now, what I'm trying to do is to load buttons to look like these:
I've tried doing the following below:
// Forms1.cs
using System;
using System.Drawing;
using System.Windows.Forms;

}
private void Form1_Load(object sender, EventArgs e)
{
int buttonCount = 3;
var buttons = new FontAwesome.Sharp.IconButton[buttonCount];
for (int i = 0; i < buttonCount; i++)
{
var btn = new FontAwesome.Sharp.IconButton
{
Text = "Button " + i,
TextAlign = ContentAlignment.MiddleLeft,
IconChar = FontAwesome.Sharp.IconChar.Book,
IconColor = ColorTranslator.FromHtml("#6A6A73"),
IconSize = 20,
IconFont = FontAwesome.Sharp.IconFont.Auto,
TextImageRelation = TextImageRelation.ImageBeforeText,
FlatStyle = FlatStyle.Flat
};
btn.FlatAppearance.BorderSize = 0;
btn.ForeColor = ColorTranslator.FromHtml("#6A6A73");
btn.BackColor = ColorTranslator.FromHtml("#FDFEFF");
btn.Dock = DockStyle.Top;
buttons[i] = btn;
}
flowLayoutPanel1.Controls.AddRange(buttons);
}
}
}

Here's what it looks like after building and running the application:
What am I doing wrong?
Form1_Load method is not subscribed to Load event of your form. Body of InitializeComponent is missing following line of code.
this.Load += new System.EventHandler(this.Form1_Load);
Insert this line before this.ResumeLayout(false);. You can fix it in designer as well.
I would like to disable the button part of a ToolStripSplitButton in a c# winforms app. As far as I see it is not possible and I would like to avoid a complex solution (rewriting entire toolstripsplitbutton) so I'm trying to disable visually at least, ie. draw a grayed icon when button part disabled.
First I browsed referencesource and found that ToolStripRenderer and ToolStripProfessionalRenderer uses some 'internal' properties and methods in OnRenderItemImage(ToolStripItemImageRenderEventArgs e) so I cannot mimic (copy-and-modify-a-bit) the behaviour of OnRenderItemImage.
Next I tried the following code.
Basically it works, the toolStripSplitButton1 is grayed out when the Tag is boolean false.
But this solution kills all my System.Windows.Forms.Timer somehow! Try this code, when toolStripSplitButton1.Tag == false then the toolstrip-independent timer1 does not tick anymore. And the toolStripSplitButton1 tooltip does not show up (guess because it uses Timer as well).
(button1 and button1_Click is just for toggle toolStripSplitButton1.Tag)
My first question is why OnRenderItemImage kills all System.Windows.Forms.Timer?
Second question is how to achieve the original aim to gray out button icon at least visually independently of the button itself?
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
toolStrip1.Renderer = new MyToolStripProfessionalRenderer();
toolStripSplitButton1.Tag = false; // this is for disabling button part
toolStripSplitButton1.ToolTipText = "toolStripSplitButton1 ToolTip";
System.Windows.Forms.Timer timer1 = new Timer();
timer1.Interval = 1000;
timer1.Tick += T_Tick;
timer1.Start();
}
int ticks = 0;
private void T_Tick(object sender, EventArgs e)
{
System.Diagnostics.Debug.WriteLine(ticks++);
}
private void button1_Click(object sender, EventArgs e)
{
toolStripSplitButton1.Tag = !((bool)toolStripSplitButton1.Tag);
}
}

{
protected override void OnRenderItemImage(ToolStripItemImageRenderEventArgs e)
{
try
{
if (e.Item.Enabled &&
e.Item.Tag?.GetType() == typeof(bool) &&
!(bool)e.Item.Tag)

e.Item.Enabled = false;
base.OnRenderItemImage(e);
e.Item.Enabled = true;

I don't think that using a timer for tracking the change is a good idea. What I suggest is create a changeOccurred event and do the operations inside the event.
Im actually trying to paint an elipse around my cursor when i moove it, I dont want it to leave a trail like it does actually.
Can someone help with this, I believe it has something to do with the invalidaterec option
Any example son using invalidate rec?
Here is my code, besides the trail it has to work the same way it does now.
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;
using System.Runtime.InteropServices;
namespace MouseTest
{
public partial class Form1 : Form
{
[DllImport("user32.dll", EntryPoint = "GetDC")]
private static extern IntPtr GetDC(IntPtr hWnd);
[DllImport("user32.dll", EntryPoint = "ReleaseDC")]
private static extern int ReleaseDC(IntPtr hWnd, IntPtr hDC);
[System.Runtime.InteropServices.DllImport("Shell32.dll")]
private static extern int SHChangeNotify(int eventId, int flags, IntPtr item1, IntPtr item2);
System.Timers.Timer t1 = new System.Timers.Timer(100);
public Form1()
{
t1.Elapsed += new System.Timers.ElapsedEventHandler(t1_Elapsed);
t1.Start();
// System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor;
//Mouse.OverrideCursor = System.Windows.Input.Cursors.Hand;
InitializeComponent();
}
void t1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
t1.Stop();
//SolidBrush b = new SolidBrush(Color.Red);
IntPtr desktopDC = GetDC(IntPtr.Zero);
Graphics g = Graphics.FromHdc(desktopDC);
g.FillEllipse(new SolidBrush(Color.BlueViolet), Cursor.Position.X, Cursor.Position.Y, 25, 25);
g.Dispose();
ReleaseDC(IntPtr.Zero, desktopDC);
t1.Start();
}
}
}
Yes, keeping the previous coordinate and calling InvalidateRect on the previous enclosing rectangle before drawing the new new ellipse would probably work. I don't have any code lying around that calls InvalidateRect, but if this is exactly your goal:" to paint an elipse around my cursor when i moove it, I dont want it to leave a trail like it does actually." there are other, more straight forward ways.
One way is to draw the ellipse on a transparent form and then move that form around based on the cursor's movement:
Here, first is the form definition:
namespace MouseForm
{
partial class Form1
{
/// <summary>
/// Required designer variable.

{

this.SuspendLayout();
//

this.shapeContainer1.Shapes.AddRange(new Microsoft.VisualBasic.PowerPacks.Shape[] {
this.ovalShape1});
this.shapeContainer1.Size = new System.Drawing.Size(74, 74);
this.shapeContainer1.TabIndex = 0;
this.shapeContainer1.TabStop = false;
//

this.ovalShape1.Location = new System.Drawing.Point(2, 2);
this.ovalShape1.Name = "ovalShape1";
this.ovalShape1.Size = new System.Drawing.Size(70, 70);
//

//

this.timer1.Tick += new System.EventHandler(this.timer1_Tick);
//

}
#endregion
private Microsoft.VisualBasic.PowerPacks.ShapeContainer shapeContainer1;
private Microsoft.VisualBasic.PowerPacks.OvalShape ovalShape1;
private System.Windows.Forms.Timer timer1;
}
}
And here is the code:
using System;
using System.Windows.Forms;
namespace MouseForm
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void timer1_Tick(object sender, EventArgs e)
{
this.Left = Cursor.Position.X - this.Width / 2;
this.Top = Cursor.Position.Y - this.Height / 2;

}
I'll leave it as an exercise to the reader to implement a way to close the transparent form :)
I have a TableLayoutPanel to which I add rows dynamically.

Does anybody know what's going on?
thanks :)
Set the AutoScroll property to True.
Make sure that the default rows that get added by the designer do not cause any trouble. Make your constructor look like this:
public Form1() {
InitializeComponent();
tableLayoutPanel1.RowCount = 0;
tableLayoutPanel1.RowStyles.Clear();
tableLayoutPanel1.AutoScroll = true;
}
Looks like you're missing tableLayoutPanel.AutoSize = true.
Try the below line which may work for you:
this.tableLayoutPanel1.AutoScroll = true;
this.tableLayoutPanel1.Dock = DockStyle.Top;
Ok... So I've got this pretty killer Screenshot system I've been using for a while... It pretty much involves creating a somewhat transparent Form that auto-sizes to fit all monitors... Which gives the screen(s) a "dark-out" effect... I then have a hidden "button" control whos position is set upon mouse-down... Then, until mouse-up, the button will resize in real-time to create a sort of "selection" area... The Button is granted full transparency to implement this effect.
Source Example: http://db.tt/LWxfDB6 [Also posted below]
I'm having two issues that are directly related, I believe.
1.) The coordinates are off for multimonitors, it properly returns the coordinates that are clicked upon (highlighted), but the highlight box (effect) is often on the wrong monitor.
2.) You can only select from top-left ---> bottom-right and not universal.
Sorry if I didn't explain it well, the source should explain better.
Thanks, in advance, for any and all help received. :)

You should implement control resizing logic easier:
void MarkRect_MouseMove(...)
{
var mouseX = Cursor.Position.X;
var originalMouseX = Point1.X;
button1.Left = Math.Min(mouseX, originalMouseX);
button1.Width = Math.Abs(mouseX - originalMouseX);
// the same for Y
}
You should post that code here. We are to lazy to go to your dropbox to see the code. There are easier questions to answer here.
