I am trying to draw a black border around a ToolStripButton. This is the code I am using and it only draws the border on 2 sides. Dim clrMenuBorder As Color = Color.Black Dim borderPen As New Pen(clrMenuBorder)
Dim rect1 As New Rectangle(0, 0, e.ToolStrip.Width, e.ToolStrip.Height)
e.Graphics.DrawRectangle(borderPen, rect1)
Even with <label>.forecolor = Color.Black. I find that my labels' borders are not {255,0,0,0} but rather {255,100,100,100), a middlish gray, Is there some system setting (e.g., themes, Silverlight) from which the standard label draws its color?( I am familiar with the sub-classing work-around, but have hundereds of instances that would have to be changed.)

View 1 RepliesI have to draw a black line across the center of the picture from one side to the other, how do I do that. Here is the code:

Dim pixel As Color

bmp = Bitmap.FromFile(tbFileName.Text)
' manipulate bmp here
lblRight.Image = bmp
I have created tooltips on a form from the toolbox and defined them as owner draw. I tied them to either a panel or a grid and they show up as black boxes the size that would contain the text that is assigned. If I had two areas next to each other, the text shows up. Neither the background or the forground color is black, so the black of the box is not from a color assignment. This has worked at one time and I do not know what changed.

View 1 RepliesDrawing a 3-D border should be easy enough, right? Nope. Does anyone know how to draw a border that looks exactly like TextBox's? Right now, I'm just drawing black lines at the top + left and white at the bottom + right but the bevel isn't nice and when the background color is white, the bottom + right don't show up.
View 8 RepliesI need to draw a border of a certain width around a new bitmap.
I want to use Graphics.DrawLines, because i may want to draw the Horizontal or Vertical borders only.
For Example:
Code:
'Add this to a button on a blank form
Dim Canvas As New Bitmap(100, 100)
Dim G As Graphics = Graphics.FromImage(Canvas)
[Code]....
Ive fiddled around with this, but i cant get the math right. What must i do to get the border of the correct width around my bitmap?
Also do i need the first "G.Dispose()"?
I see that the Line method is replaced with DrawLine, however; it seems like DrawLine must treated as an object as follows:
Private Sub Form1_Paint(ByVal sender As Object, ByVal e _
As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
Draw a solid black line 25 pixels from the top of the form.[code].....

Under the MouseLeftButtonUp event handker store the first coordinates of the lines second endpoint. Then call the length method to obtain the distance between the two endpoints(the lines length). Fianlly display the line on the canvas and the line's length in the Length=Label. Below is the code I have so far. There are no errors, but when I run the application nothing happens.
Private Sub lineCanvas_MouseLeftButtonUp(ByVal sender As Object, ByVal e As System.Windows.Input.MouseButtonEventArg... Handles lineCanvas.MouseLeftButtonUp
Dim distance As Double
endPoint = e.GetPosition(lineCanvas)

View 1 RepliesI have a toolstrip in my main form, at the bottom. The main form has menus that lead to other forms. I am trying to get a button to appear on the toolstrip each time a form opens. My button creation code works. Here is what I have so far:
Public Sub buttons()
'Each form has a Me.FormClosing and MyBase.Load event that links to this sub.
ToolStrip1.Items.Clear()
ToolStrip1.Items.Add(ToolStripDropDownButton1)
For Each frm As Form In My.Application.OpenForms
[Code]...
I have tried using the Tag property to choose the form, but it hasn't worked.I have also tried using the My.Application.OpenForms property to open the form, but this also hasn't worked.I really don't fancy using loads of If Then Else statements to hide and show buttons that have already been created, as this seems rather messy.
I have a textbox, a standard button and a toolstrip containing a couple of buttons. In the validating event of the textbox i coded to check whether it is blank. If yes then it shows a message 'Enter Value'. When the standard button is clicked while the textbox is empty, it's validating properly and showing the message but when the toolstripbutton is clicked it's not not validating the textbox and no message is being shown. It seems that I gotto write the validation code explicitly in the toolstripbutton_click event which is too troublesome when there are multiple textboxes and toolstripbuttons on a single form. What I want to know is whether the textbox_validating can be fired while the toolstripbutton is clicked? Handling toolstrips is really a headache. I'm badly in need of it.

View 2 RepliesI'm making an MDI child window switcher (to set focus on selected child) sort of in a windows-style taskbar at the bottom of the program. I've got things set up so that when a child window is opened, a toolstripbutton is created and added onto the toolstrip and contains the window number and window type (what the window does). All that runs very well, but when I want to close a child form, I need to dispose the button that corresponded to it. I tried something like this:
For Each C As Control In frmClient.Controls
If TypeOf C Is ToolStrip Then
For Each tButton As ToolStripButton In C.Controls

But nothing happens at all. Is there a practical method to do this or am I missing something?

I have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing. But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events. What it seems to be is it's not committing the change in any cell under editing. [Code]
Why isn't it happening and how can I make it work? how can I fire datagridview_ cellvalidating, datagridview_rowvalidating and other events; and commit cell value change by clicking toolstripbutton.
