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 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 have a panel that has a collection of custom drawn controls. I know how to programmically scroll the panel but the problem is how the controls draw when scrolling. when scrolling right the control shows as normal but when scrolling left it is not looking correctly. This just the start of the complete application so I just have some basic testing in place right now. Need to find a way for the control to draw correctly when scrolling.
Form code:
public partial class Form1 : Form
{
Panel pn;
private int location = 0;
public Form1()
{
InitializeComponent();
pn = new Panel()
{
Width = this.ClientRectangle.Width - 20,
Height = 120,
BackColor = Color.Black,
Left = 5,
Top = 20
};
pn.AutoScroll = false;
pn.VerticalScroll.Maximum = 100;
pn.HorizontalScroll.Maximum = this.ClientRectangle.Width - 100;
pn.VerticalScroll.Visible = false;
pn.HorizontalScroll.Visible = false;
pn.AutoScrollPosition = new Point(0, 0);
pn.AutoScroll = true;
this.KeyPreview = true;
this.KeyDown += new KeyEventHandler(keyPress);
for(int i = 0; i<10;i++)
{
CustomControl1 cc = null;
if (i % 2 != 0)
cc = new CustomControl1()
{
isOdd = true,
Width = 100,
Height = 100,
Left = (100*i)+5,
Top = 0
};
else
cc = new CustomControl1()
{
isOdd = false,
Width = 100,
Height = 100,
Left = (100 * i) + 5,
Top = 0
};
pn.Controls.Add(cc);
}
this.Controls.Add(pn);
}
private void keyPress(object sender, KeyEventArgs e)
{
switch (e.KeyCode)
{
case Keys.A:
if(location - 20 >0)
{
location -= 20;
pn.HorizontalScroll.Value = location;
}
else
{
location = 0;
pn.AutoScrollPosition = new Point(location, 0);
}
break;
case Keys.D:
if(location +20 < pn.HorizontalScroll.Maximum)
{
location += 20;
pn.HorizontalScroll.Value = location;
}
else
{
location = pn.VerticalScroll.Maximum;
pn.AutoScrollPosition = new Point(location, 0);
}
break;
}
foreach(Control c in pn.Controls)
{
c.Invalidate();
}
}
}
Control Code:
public partial class CustomControl1 : Control
{
public bool isOdd { get; set; }
public CustomControl1()
{
InitializeComponent();
}
protected override void OnPaint(PaintEventArgs pe)
{
Graphics gr = pe.Graphics;
Rectangle rc = new Rectangle(pe.ClipRectangle.X,pe.ClipRectangle.Y,100,100);
Brush br = new SolidBrush(Color.Red);
if (isOdd)
br = new SolidBrush(Color.Yellow);
gr.FillEllipse(br, rc);
base.OnPaint(pe);
}
protected override void OnPaintBackground(PaintEventArgs pe)
{
base.OnPaintBackground(pe);
}
}
Don't clip your drawing:
//Rectangle rc = new Rectangle(pe.ClipRectangle.X, pe.ClipRectangle.Y, 100, 100);
Rectangle rc = new Rectangle(0, 0, 100, 100);
i have a button in my form and for every button click it is adding groupBox. but i want a winform contain only 8 groupboxes. when the numbers of groupBox reach 8 it will automatically do Visible=false all 8 before groupBox and again adds a groupBox named(groupBox9). what must i do?

define an integer class variable and increase it everytime the button is clicked. After increasing it, check if it's greater than 8. If it is, set your stuff to Visible = false.
Mock up:
public class MyClass
{
private int groupboxCounter = 0;
public MyClass()
{
}
private void btn_click(...)
{
// add a new groupbox here
groupboxCounter++;
if (groupboxCounter > 8)
{
//make stuff invisible here
}
}
}
I am trying to add different objects to a GroupBox. When I click 'Add Title' button I can get the Combobox and Textbox to appear in the Groupbox.
What I want to now happen is when they click 'Add question' I want to be able to add the questions objects (Combobox, Textbox) to the same Groupbox as the last added title.
C# CODE:
private void btnAddTitle_Click(object sender, RoutedEventArgs e)
{
CurrentSortItem++;
SortItems.Add(CurrentSortItem);
StackPanel sp = new StackPanel() { Orientation = Orientation.Horizontal };
gp = new GroupBox();
ComboBox y = new ComboBox();
y.Name = "Combo" + CurrentSortItem;
y.SelectedItem = CurrentSortItem;
y.Height = 25;
y.Width = 45;
y.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
y.Margin = new Thickness(20, 15, 0, 0);
foreach (int item in SortItems)
{
y.Items.Add(item);
}
TextBox x = new TextBox();
x.Name = "Title" + CurrentSortItem;
x.Text = "Title...";
x.FontWeight = FontWeights.Bold;
x.FontStyle = FontStyles.Italic;
x.TextWrapping = TextWrapping.Wrap;
x.Height = 25;
x.Width = 200;
x.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
x.Margin = new Thickness(12, 15, 0, 0);
sp.Children.Add(y);
sp.Children.Add(x);
gp.Content = sp;
spStandard.Children.Add(gp);
}
private void ViewQuestions(StackPanel sp)
{
gp.Content = sp;
}
List<int> SortItems1 = new List<int>();
int CurrentSortItem1 = 0;

private void btnQuestion_Click(object sender, RoutedEventArgs e)
{
if (SortItems.Count == 0)
{

}
else
{
Count++;
CurrentSortItem1++;
SortItems1.Add(CurrentSortItem1);
StackPanel sp = new StackPanel() { Orientation = Orientation.Horizontal };

ViewQuestions(sp);
}
I have tried to have an attempted but when I click 'Add Question' it just overwrites the Title's objects.
Any help would be amazing.
I am using WPF, and these are created at runtime.
Thanks.
EDIT4:
I have had to move
StackPanel outerSp = new StackPanel() { Orientation = Orientation.Vertical };
StackPanel sp = new StackPanel() { Orientation = Orientation.Horizontal };
GroupBox gp;
Just below the
public partial class CreateNewStandard : Page
{
So it is visible to all the methods. Then I get this error.

You are overwriting it .Though you need to add them to the already existing stackPanel. The code is not tested I am trying to give you an idea .I hope this will help.
