VS 2008 Owner Drawn Combobox The Border?
Jan 26, 2011
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.

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?

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 "
[code]....
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.

i 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.

I want to write a vb program to allow user to draw rectangle. User can click on a point as starting position and drag on the screen. A rectangle is drawn with the current mouse position and the starting position. The user then release the mouse as end position. When the rectangle is drawn, user can resize the rectangle by drag the border of the rectangle.

When I populate a combobox with items that have a line and text drawn in the DrawItem event, only the line image for the first item in the list appears in the drop down portion of the combobox. The other items (index>0) shown in the drop down portion of the combobox do not contain an image of the line, yet each item in the list does contain the designated text. The correct line image does appear when the user selects an item and the drop down portion of the combobox is not visible. How can I get the line image to appear in every item of the combobox when the drop down list is activated?

I've created an ownerdraw ComboBox (used as DropDownList only) in Visual Basic .NET 2010. I inherited ComboBox and set DrawMode to OwnerDrawVariable. The control itself and the dropdown items are drawn with Paint and DrawItem.
The control works fine so far, but there is one thing i was unable to change: When i click on the combobox to open the dropdown area, this new area has a very bright border color (nearly white) which I want to change to black. I've uploaded an image of the current control and how I want it to look like:

1) Draw three letter's 'P' 'B' & 'C' on a form (at a later date mutiples of each wil be added)
2) to be able to drag them anywhere on the form
3) to be able to lassoo them and drag them all at the same time.
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?

MS released the new MSChart for .net 3.5 sp1. I'm trying to get the hang of it in VS2008. One big issue I have is that if I have no data plotted the chart area axis's aren't drawn. Does anyone know a way around that? That seems like a pretty basic/common issue.

This may seem like a dumb question... But what color is the border of the default TextBox control?
I need to replace a few TextBox's with a RichTextBox in my application, and now I have TextBox's and RichTextBox's mixed up, which does not look very nice since they have different borders. An RTB with BorderStyle FixedSingle has a black border by default, while the TextBox has kind of a blueish color (in XP, standard blue theme). If I use the gray theme, it's a gray border, etc.
I am drawing the border of the RTB manually so that I can match it with the border of the TextBox, but I cannot find the correct SystemColor to use for this... Obviously I cannot just find the RGB value, because it will change if the user uses a different theme. I need it to match the color of the TextBox border whatever the theme. I thought I could use the SystemColors for that, since they change when you change the theme.
I've been trying in the Xp blue theme, but none of the SystemColors seem to match the TextBox border exactly.
Can I maybe find the name of a SystemColor from an RGB value, or something like that?

I'm currently working on an application that I'd really like to be able to have a custom form border. I have it set up right now that the close, minimise and maximise buttons work, as well as moving it around. The issue however is that, although the movement is working, once it starts, it does not stop. So I can drag it around and it works perfectly, but if I want to stop dragging it around and click elsewhere, the form moves to the position from which it was being dragged.

I need a check that will see the location of the edge of the form. An example would be (for what I am trying to do) is, when a form is moved, the main form will get bigger depending which border and which way the second form is going.So basically I need some way to make Form1 get bigger if Form2 is near the left border or near the bottom border.
*I have a mini system for making it grow(LocationChanged) on the form I want it to work for.
*I also know about ".left" and ".top",
