how would i go about creating an ownerdrawn dtp, with highlighted dates in the dropdown + also in the collapsed view when a highlighted date is selected? i'm guessing i'd have to inherit a dtp + then handle an event or 2. does anyone have any insight or experience with this?

Ok so i have an owner drawn combobox and everything is fine in the drawitem event,except i'm a perfectionist and there is no border i have a beige backcolor, and i really just want a black border or something first i tried to draw using the given graphics and the given bounds, it failed as the rectangle was drawn oddly inside the combobox for some reason (not on the inner border, almost in the center of the combobox.then i tried the following and was surprised when it didnt work
Dim z2fx As Graphics = Graphics.FromHwnd(cmbBox.Handle)
z2fx.DrawRectangle(Pens.Black, New Rectangle(0, 0, cmbBox.Width, cmbBox.Height))
then i tried this and thought for sure it would work
1 Dim zfx As Graphics = Graphics.FromHwnd(cmbBox.Parent.Handle)
zfx.DrawRectangle(Pens.Black, cmbBox.Bounds)
this drew 2 sides of the border, the bottom and the right then i realized something: the code i used earlier with z2fx made the upper and left borders flicker right when i click the drop down, then it goes away. It is as if they were being redrawn with the background color of the combobox. And this redrawing was taking place after the drawitem event was called.
Something, some event, keeps redrawing the background color of the combobox when i put a button on the form and associate it with the zfx2 code, then when i press this button the combobox draws the 2 borders (upper and left) and they stay drawn until i either hover over the combobox or open the drop down of the combobox.
nvm while typing this i figured out a solution i can use the mouseenter mouseleave and dropdown events
since i typed this already im posting it anyway if i have problems i will let you know.EDIT: failed.SOMETHING keeps redrawing the damn background only after most events have passed! i tried the backgroundcolorchanged event it didnt work. this is annoying.
I created an image (.png) with a transparent background and I'm trying to show it in a ListView. So I added the image to the ImageList belonging to the ListView, however when drawn, there is a partial white circle around the image. I checked and rechecked the actual image and there are absolutely NO white pixels at those positions.

I'm trying to create an owner drawn TabControl that looks like the tabs in Visual Studio on XP (might look different in Vista, not so sure).So far, I've got the background and the blueish border, and now I've run into some trouble drawing the 'tab headers' (where the text is displayed).Here's what I got so far:
vb.net
Imports System.Drawing.Drawing2D
Public Class cTabControl
#Region " Colors "

Why isn't this working? How do I draw a border like this around a 'normal' OwnerDrawn tabcontrol, without the funky SetStyle method..?also, the DoubleBuffer ControlStyle (in the SetStyles method) option is not listed in the Intellisense list, but it is accepted when I finish typing it... Is that a bug?
I tried to add icons to the items in the listbox(owner drawn listbox- variable). I m able to do it. But after adding the items, according to my requirement i need to remove few items now and then.I used:Listbox1.Items.Remove("Aqua")This removes the last item from the listbox instead of the mentioned one. the same is done even if i try to remove the selected index item.
View 2 Repliesi have an owner drawn list box which is connected to a SQL database source. When the list box is owner drawn, my list box is filled with the text "System.Data.DataRowView". When i turn off owner drawn it works perfectly.
The problem is, i need it to be owner drawn as it is a crucial part of my program. Is there a way of keeping my owner drawn list box and preview the data from the SQL database at the same time? Here is my code for the owner drawn part, most of this is irrelevant, just mainly look at the bottom bit where i print the string, with the variable 's' and 'drawstring':[code...]
I'm trying to implement an Owner-drawn ListView in my application using the code available at this MSDN article, however I've encountered several issues.First of all, the double-click event only fires when the mouse is over the text in the first column of any ListViewItem. I'd prefer to keep the manual, timer-based, double-click detection routine as a last resort if possible.Second, when the ListView is scrolled sideways, clicking an item won't select it anymore.

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

For the moment the third option isn't important just as long as l can drag the letters.
On my form, I have a picture box that starts off blank, but draws lines according to mouse click events.
I am now trying to test whether there is colour in individual pixels, yet I am yet to find solid code.
My initial code was along the lines of
Dim bitm as bitmap
bitm = PictureBox1.Image
This would come up with nothing, as there wasn't any image assigned to the picture box.
I was wondering how I could save the lines drawn and use that as a bitmap to test pixel colour.
If you make a Control's BackgroundColor Transparent and put it in front of another control, the other control doesn't show through. Why not? GDI+ makes this easy, doesn't it? Why don't Windows Forms use it?

View 6 RepliesDoes anyone know what is the best way to check has datetimepicker been clicked and value selected before saving and updating database. I am working on a database app and database field for "Date" does not allow null so in order for app to work properly i would like before saving to check if the date is selected and if not to create warning for user. I have created that for "Name" and other columns, but those are text boxes so I had no problem with that. I could change the database field for "Date" to allow null, but that the easyer way and not what I really want. If someone has solution for problem

I am having trouble with the datetimepicker. I use this and I tried as many as I could but didn't get a proper result, this one is the closest, so atleast while debugging I can see it having the right value:

How can I get the datetimepicker value to have a 2 digit day EX. If it was November 6, 2009 the value is showing as 11/6/2009 but I need it to be 11/06/2009
I have a search that searches by date and Im using the datetimepicker. the date format in from my sql database is in MM/DD/YYYY not MM/D/YYYY So my results come up ok if the day is a 2 digit day normally (ex. 11/20/2009)but if its a single date (11/6/2009) I don't get any results because it is looking for 11/06/2009 I don't see how I can get the value of datetimepicker to be MM/DD/YYYY Even if i set the custom format to MM/dd/yyyy the value is showing up as MM/d/yyyy
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?

I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.
We have this custom DateTimePicker in our project where you can alter the BackColor and so on. But normally, when you click on the month of a DateTimePicker, it gets highlighted and you can change it with for example the arrow buttons on your keyboard or by typing a different number. Now the problem is that in our DateTimePicker, the highlighting doesn't happen anymore. When you click on for example month, you'll be able to change month but you don't see wether you selected month or something else.
This is the code we have (it's old code from way before I even started working here):
