I have a multi monitor setup and I want to paint a vertical and horizontal line as the user moves their cursor. The lines I want to paint should span all monitors. I'm not entirely sure how to adjust my form to make this possible since when i make it full screen it only maximizes to one monitor.
Do i have to make a form per monitor and send signals to each one when the cursor moves for it to repaint the line?

I have a WinForms application that has a TableLayoutPanel; this is the definition code:
tableLayoutPanel1 = new TableLayoutPanel();
tableLayoutPanel1.Dock = DockStyle.Fill;
tableLayoutPanel1.AutoScroll = true;
tableLayoutPanel1.RowCount = users.Count + 1;
tableLayoutPanel1.ColumnCount = 1;
tableLayoutPanel1.GrowStyle = TableLayoutPanelGrowStyle.FixedSize;
tableLayoutPanel1.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 100F));
foreach (String user in users)
{
tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.Absolute, 600F));
}
tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.Absolute, 600F));
int index = 0;
foreach (String user in users)
{
AddDockedControl(index, user);
index++;
}
AddDockedControl(index, null);
panel1.Controls.Add(tableLayoutPanel1);
private void AddDockedControl(int row, String userName)
{
AccountRowUC newUser = new AccountRowUC(this, userName, row);
newUser.BorderStyle = BorderStyle.FixedSingle;
newUser.Dock = DockStyle.Top;
tableLayoutPanel1.Controls.Add(newUser, 0, row);
}
Now, when I want to remove one of the rows, I'm using this code:
public void RemoveRowAtIndex(int index)
{
if (index >= tableLayoutPanel1.RowCount)
return;
// delete all controls of row that we want to delete
for (int i = 0; i < tableLayoutPanel1.ColumnCount; i++)
{
var control = tableLayoutPanel1.GetControlFromPosition(i, index);
tableLayoutPanel1.Controls.Remove(control);
}
// move up row controls that comes after row we want to remove
for (int i = index + 1; i < tableLayoutPanel1.RowCount; i++)
{
for (int j = 0; j < tableLayoutPanel1.ColumnCount; j++)
{
var control = tableLayoutPanel1.GetControlFromPosition(j, i);
if (control != null)
tableLayoutPanel1.SetRow(control, i - 1);
}
}
// remove last row
tableLayoutPanel1.RowStyles.RemoveAt(tableLayoutPanel1.RowCount - 1);
//tableLayoutPanel1.RowStyles.RemoveAt(index);
tableLayoutPanel1.RowCount--;
}
The problem is that when I remove a Row, a big space is left at the bottom of the table: the TableLayoutPanel won't reclaim the size of panel1.
A solution base on the layout described in the comments and this answer, previously posted:
Center multiple rows of controls in a FlowLayoutPanel
Description:
(Full code of a test Form provided at bottom of this post)
Create a new Form (here, named frmTLPTest1)
Add two Panels. One is used to host some buttons, the other one will be the Container of a TableLayoutPanel.
Set the Container panel to AutoScroll = true, AutoSizeMode = AutoSizeMode.GrowAndShrink, set all the Anchors (Left, Top, Right, Bottom)
Inside the Container panel, drop a new TableLayoutPanel: set it to AutoSize = true, AutoSizeMode = AutoSizeMode.GrowAndShrink, Dock = DockStyle.Top
Remove all Rows and Columns from the TableLayoutPanel except one of each (you cannot remove all). Set the dimensions of both to AutoSize.
Important note (also reported in the linked answer):
In the Form constructor, one of the RowStyles is removed. This is
important: the TLP will keep 2 RowStyles. One is applied to the
existing Row; the second style will be applied to the first Row you
add: to the first one only, not the others. If this style is not
removed, it will compromise the layout.
The core methods used to Add Rows to/Remove Rows from the TableLayoutPanel, make use of a FlowLayoutPanel as the TLP Row content and can also be used as Container of other controls, eventually.
TlpAddRow(TableLayoutPanel tlp, bool addRowCount) method:
Adds a new FlowLayoutPanel to the Cell of the TableLayoutPanel specified and adds a new Row if requested.
Since the Designer won't allow to remove all the Rows, the First Row (FlowLayoutPanel) must not increment the Rows count: the addRowCount argument will be set to false.
private Control TlpAddRow(TableLayoutPanel tlp, bool addRowCount)
{
var flp = new FlowLayoutPanel() {
Anchor = AnchorStyles.Top | AnchorStyles.Bottom,
AutoSize = true,
AutoSizeMode = AutoSizeMode.GrowAndShrink,
};
tlp.SuspendLayout();
if (addRowCount) tlp.RowCount += 1;
tlp.Controls.Add(flp, 0, tlp.RowCount - 1);
tlp.ResumeLayout(true);
return flp;
}
TLPRemoveRow(TableLayoutPanel tlp, Control control) method (overloaded):
Allows to remove a Row from the specified TableLayoutPanel. The Row to be removed can be derived from the Control that is used as the Row Container (a FlowLayoutPanel, here, but it could be a Panel, another TableLayoutPanel, or some other type of Container control).
The Row can also be removed by directly specifying the Row index.
private void TLPRemoveRow(TableLayoutPanel tlp, Control control)
{
int ctlRow = tlp.GetRow(control);
TLPRemoveRow(tlp, ctlRow);
}
private void TLPRemoveRow(TableLayoutPanel tlp, int row)
{
if (row < tlp.RowCount - 1) {
for (int i = row; i < tlp.RowCount - 1; i++) {
tlp.SetRow(tlp.GetControlFromPosition(0, i + 1), i);
}
}
tlp.RowCount -= 1;
}

I am new to c# and I'm trying to understand z-index concept. So far I have a simple form created using ConsoleApplication project in visual studio. There are 3 cs files. Here's the code:
In Algorithm.cs (inherited from UI.cs):

bottom.Controls.Add(test);
test.BringToFront();
ball_bounding_box_x_coord = middle.Size.Width / 2 - width / 2;

The problem I'm having is that the test button is not visible. If i remove the bottom panel and add the test button directly on the form then it is visible. Why doesn't it appear on the bottom panel even after I used bringtofront() ?
Why doesn't it appear on the bottom panel even after I used bringtofront() ?
Because you've placed it outside the visual boundary of the panel:
test.Location = new Point(0, 800);
That sets the position of the button to a horizontal offset of 0 and a vertical offset of 800. The bottom panel is only 140 pixels high, so 800 is well below the bottom of the visible area.
It's not really clear what you meant to do. Given that the window width is 1600 pixels and 800 is half that, maybe you just transposed the X and Y coordinates and meant this instead:
test.Location = new Point(800, 0);
That would place the button in the middle of the panel, aligned to the top.
Other than that, I can't imagine why if you wanted the button to be visible, you would hard-code a location for it that is not in a visible area.
I am doing C# application, and I want to change the style of a message box. Is it possible or not?
Example: change button style, fore color, etc.
You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:
FormBorderStyle FixedToolWindow
ShowInTaskBar False
StartPosition CenterScreen
To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:
MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
// etc
}
It would be advisable to add your own Show method that takes the text and other options you require:
public DialogResult Show(string text, Color foreColour)
{
lblText.Text = text;
lblText.ForeColor = foreColour;
return this.ShowDialog();
}
MessageBox::Show uses function from user32.dll, and its style is dependent on Windows, so you cannot change it like that, you have to create your own form

I've created a custom control in C#. A highly-simplified version of it is shown below:
class WellControl : Control
{
Pen circlePen = new Pen(Color.Black, 5);
Brush wellShader = new SolidBrush(Color.BlueViolet);
Brush wellBlanker = new SolidBrush(Color.LightGray);
public WellControl(int wellNum)
{
InitializeComponent();
}
private void DrawWell()
{
using (Graphics well = this.CreateGraphics())
{
this.Size = new Size(WellSize, WellSize);
if (this.selected)
{
well.FillEllipse(wellShader, ellipseCoords);
}
else
{
well.FillEllipse(wellBlanker, ellipseCoords);
}
well.DrawEllipse(circlePen, ellipseCoords);
using (Font wellNumberFont = new Font("Arial", 14, FontStyle.Bold))
{
well.DrawString(WellNum.ToString(), wellNumberFont, Brushes.Black, new Point(13, 13));
}
}
}
private void WellPaintEventHandler(object sender, EventArgs e)
{
DrawWell();
}
private void InitializeComponent()
{
this.SuspendLayout();
this.Paint += new System.Windows.Forms.PaintEventHandler(WellPaintEventHandler);
this.ResumeLayout();
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
if (disposing)
{
//dispose all the custom stuff
}
}
}
When I add it to a form, it renders properly (again, simplified example):
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
for (int i = 0; i < 4; i++)
{
WellControl newWell = new WellControl(i + 1);
newWell.Location = new Point(15, 50 * i);
newWell.Size = new System.Drawing.Size(45, 45);
this.Controls.Add(newWell);
}
}
}
I have another custom control, "Plate", which is intended to hold many "Wells". The code intended to draw the wells evenly across the plate probably sucks right now but I'm just trying to see something:
class PlateControl : Control
{
Pen blackPen = new Pen(Color.Black, 3);
public PlateControl()
{
this.Size = new Size(600, 800);
List<WellControl> plateWells = new List<WellControl>();
int column = 1;
int row = 0;
for (int i = 1; i <= 96; i++)
{
column = Convert.ToInt32(Math.Ceiling(Convert.ToDecimal(i / 8)));
row = i % 8;
WellControl newWell = new WellControl(i + 1);
newWell.Name = "wellControl" + i;
newWell.Location = new Point(column * 50, row * 50);
newWell.Size = new System.Drawing.Size(45, 45);
newWell.TabIndex = i;
newWell.WellSize = 45;
plateWells.Add(newWell);
newWell.Visible = true;
}
InitializeComponent();
}
private void InitializeComponent()
{
this.SuspendLayout();
this.Paint += new System.Windows.Forms.PaintEventHandler(PlatePaintEventHandler);
this.ResumeLayout();
}
private void DrawPlate()
{
using (Graphics plate = this.CreateGraphics())
{
Point topLeft = new Point(0, 0);
Point topRight = new Point(600, 0);
Point bottomRight = new Point(600, 400);
Point bottomLeft = new Point(0, 400);
plate.DrawLine(blackPen, topLeft, topRight);
plate.DrawLine(blackPen, topRight, bottomRight);
plate.DrawLine(blackPen, bottomRight, bottomLeft);
plate.DrawLine(blackPen, bottomLeft, topLeft);
}
}
private void PlatePaintEventHandler(object sender, EventArgs e)
{
DrawPlate();
}
}
If I add this control to a Winform using this.Controls.Add(new PlateControl()), the rectangle renders, but not the WellControls I added to the PlateControl in the constructor loop. What am I doing incorrectly?
You need to add List of WallControl to plate control.
public PlateControl()
{
this.Size = new Size(600, 800);
List<WellControl> plateWells = new List<WellControl>();
int column = 1;
int row = 0;
for (int i = 1; i <= 96; i++)
{
column = Convert.ToInt32(Math.Ceiling(Convert.ToDecimal(i / 8)));
row = i % 8;
WellControl newWell = new WellControl(i + 1);
newWell.Name = "wellControl" + i;
newWell.Location = new Point(column * 50, row * 50);
newWell.Size = new System.Drawing.Size(45, 45);
newWell.TabIndex = i;
newWell.WellSize = 45;
plateWells.Add(newWell);
newWell.Visible = true;
}
this.Controls.AddRange(plateWells.ToArray());
InitializeComponent();
}
I need a help on this,
There are 3 picture boxes, red should grow its Width to left, green should grow its height to top blue's width to right
also if one reaches the top border / any text boxes it should give an error / stop execution
I need to add more picture boxes in future and if two of them collides it should give an error / stop execution. I have managed to code them to go up, however unable to get other functions working. Please some one help me with this.
