Owner Draw Tooltip Shows Up As A Black Box
Aug 29, 2011
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.

If i have a NotifyIcon is it possible to owner draw the balloon tip for it?If not i was thinking it would have to be done this way:Work out if the icon is visible or not (as in not collapsed in windows vista / 7 / xp), and if not call ShowBalloonTip to force the icon visible then hide the balloon somehow. Work out the rect in relatio

I have a listbox which works perfectly fine in regular mode. I'm experimenting with the other modes which allow you to switch font.
As soon as I go to ownerdraw mode, either variable or fixed, it is blank when I try to add items to to it. It throws no error but just doesn't do anything. There has to be something else I have to do, to tell it how I want to display it. But I don't know what. I'm using version 2003 of .NET I'm using "Items.add" to add items.
I'm using this line to set font :
lbox.Font = New Font("Arial", 8.25, FontStyle.Bold, GraphicsUnit.Point, Nothing)
Then I'm setting it unbold later.Why is it working perfectly fine without owner draw? Granted it isn't changing the font but it's working fine. What do I have to do to make it work otherwise, so that I can change the font?It's pretty much a standard listbox, without many changes made to the properties.

some controls(e.g. buttons/labels) dont have a drawmode property. Im looking to create buttons with rounded corners because they just look nicer :P. Now, the problem is that even when you have a custom paint event, the button just gets drawn first and the custom paint event will draw on top. Especially with rounded corners, where you see the parts of the default button in the corners. Is there a way to only execute the custom paint event / block the default paint?

I've added a ribbon bar to the top of my main form using the DotNetBar and the problem is that it shows a black rectangle area instead of the default blue color. This only happens when I am using Windows 7 aero and is not maximized.

Im working on in VB.net. Basically I�m trying to create a nice looking control that draws several PNG images (stars in this example) that light up as you hover the cursor over them. This side of things is working perfectly (see picture 1).
[URL]
The problem is trying to make it work using a transparent background for the control. I can make the control transparent by setting the controls back color and using Me.Setstyle to enable transparency support, but every time the image refreshes to show any lit stars it repaints over the stars again � making the shaded areas darker each time. This results in a horrible mess (see picture 2).
[URL]
Next I tried to clear the background each time a repaint occurs so that the stars are drawn on a blank canvas each time to stop this problem. The only way I know how to do this is to use graphics.clear(Color.Transparent) before my code to paint the star images. But this does not work as the control shows a black background instead of a transparent one (see picture 3)!
[URL]
away the background to leave me with a transparent canvas to paint images onto? And is anyone smart enough to come up with a solution to this irritating issue?

I have a ToolTip on a TextBox control. When I hover the cursor over the TextBox the ToolTip appears as expected. But if the ToolTip disappears after it's AutoPopDelay time has expired or if I click on the TextBox while the ToolTip is still showing, then the ToolTip will not appear again when I hover the cursor over the TextBox. Is there any way to cause the ToolTip to reset so it shows up again?

I have a small non mdi form with only 3 controls. The user can select a name of an animal on a listbox and a thumbnail picture of it is shown on the picturebox. There is also a tton.The tooltip on the thumbnail is quite important as left/right click do different actions but for some reason the tooltip will not display unless the user clicks the form.

Dim rect1 As New Rectangle(0, 0, e.ToolStrip.Width, e.ToolStrip.Height)
e.Graphics.DrawRectangle(borderPen, rect1)

Not a single site anywhere, and I have even tried the MSDN, that details in any specific language how to draw a custom icon into a tooltip.
I have tried using every format of image I can produce, including (but not limited to) ICO, PNG, GIF, BMP, JPG etc... But every time, the app debugger clouts me round the head in defiance.. Windows Vista CAN do it.. and as in the image above.. StarDock figured it out..
I know your policy is to have the askee produce their code first, but the thing for me is
Also, I wonder if it would not be possible to take the code that does do the whole shabang, and compile it into a DLL or something that I can just embed for future projects - again this can be uploaded for others to refer to.

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].....
When I attempt to use this code (call it), I must somehow bring about an event, but I haven't found how to do that.How do I "call" this sub?

How does the CheckBox control draw that black check mark in the white box? I can't install .Net Reflector or anything here on my work machine so could someone post the code (vb.net or c# is fine with me)?
Or if anyone knows how to do it (I have an 8x8 Bitmap object I'm drawing on already) I'd like a hand since my math isn't working out correctly[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)

Currently use word automation to mail merge some documents and print etc. A stand alone PC manage this, which means that when the document gets sent to the print queue it always has an 'owner' of the name of the stand alone PC.

I'm currently working on a project in which at one point, the user may right click a button which brings up a contextMenuStrip. I am already able to find the owner accurately from that strip, and manipulate the button clicked as follows:
Dim myItem As ToolStripMenuItem = CType(sender, ToolStripMenuItem)
Dim cms As ContextMenuStrip = CType(myItem.Owner, ContextMenuStrip)
Dim buttonPressed As DataButton = DirectCast(cms.SourceControl, DataButton)
But now for the tricky part. Within this contextmenuStrip, I have a DropDown menu with multiple items in there. I would assume you would be able to work your way up the ladder doing casts like above in the manner of
ToolStripDrowpDownItem > ToolStripDropDownMenu > ToolStripMenuItem > ContextMenuStrip
Unfortunately, when I try to get the sourcecontrol from this menuStrip, it return Nothing. Any ideas on how I can get the button that was pressed from this toolStripMenuItem? My current code is as follows (in which the sourceControl is Nothing)
Dim myItem As ToolStripDropDownItem = CType(sender, ToolStripDropDownItem)
Dim dropDown As ToolStripDropDownMenu = CType(myItem.Owner, ToolStripDropDownMenu)
Dim menuItem As ToolStripMenuItem = CType(dropDown.OwnerItem, ToolStripMenuItem)
Dim cms As ContextMenuStrip = CType(menuItem.Owner, ContextMenuStrip)
Dim buttonPressed As DataButton = DirectCast(cms.SourceControl, DataButton)
how to go about doing what I did in that first method, but just working my way up from further down the ladder?
