I'm trying to achieve "disabled" affect of my form when running some process. I thought the best way to implement this was to somehow paint an overlay on top of the whole form with some gradient light gray color. But it seems like using the Form Paint event paints under all child controls. Is there a way to achieve this effect? I think I have seen somewhere else where some sort of snapshot is taken of the whole form and converted to grayscale but I need the form to be sizeable still.
In VS 2005, I have a form with a few controls (comboboxes and labels) that won't display when the form loads. The controls show up as transparent "holes" in the form, through which I can see my desktop. As soon as I move the form, or left-click on the title bar for about a second (without moving the nouse) the controls render correctly.What do I need to do to get these controls to display correctly, short of forcing a resize?
How can microsoft paint(or any other painting software) be included in a VB.net project? I need to used its functionalities to maipulate jpg and movie file. Is there any ways this can be done on VB.net (or Visual Studio).
The only way I know to force a paint event in my pictureboxes is to do a 'Picturebox1.invalidate'. I read that this isn't the best way to do it though, so what's the best way to make my picture boxes repaint?
Weird issue: I have application that I fire some code in the Form_Paint event for the main form, it works fine on my machine, but on other machines is not working at all.
I tried to debug the code on the other machine, and Form_Paint event is not triggered at all!
I created a simple application to display the current Date/time on a Form (see below). When the application runs, the amount of memory used continues to grow. I don't see any obvious problems. I am running Visual Studio 2008 on Vista Business OS.
I was wondering how i would go about threading a paint event. I know the basic multithreading but i cant figure out how i would go about applying this on a paint event. This is the way i know how to go about multithreading.
how would i paint an image onto a form according to the mouse position? i have a sprite and i want the front of the sprite to always face the mouse cursor.
Ive been hacking away at this portion of a project for some time and I have a Picbox in a panel, I can, Draw on the image no problem, I can pan and then draw on the image, no problem. How ever when I zoom in out out on the image I can no longer draw on the zoomed image. How ever if I try and draw then zoom again, the lines will show up, but in the wrong places
however it will draw it behind objects for example if i have a groupbox it will draw(i assume its still drawing at leaste) behind the group box and i cant see it
I have seached through the net to find a solution to customize the scrollbars on a datagridview. I found some stuff, but this seem to be not very easy.
I have figured out, or think to have figured out, that the new way of doing arcs and lines does not require the HDC, so that problem is solved. The problem I am having now is that with the new way, every example I have found created a sub that does the drawings, like:
Public Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint Dim radius As Integer = 20 Dim diameter As Integer = radius * 2
[code]....
Is there anyway to pass values to this sub? I have to draw several arcs and lines and the values for them are different everytime. I would like to create a sub that would be used in every spot the old program used the old arc command and pass the needed values through it.
I've used this example to create a paint application in vb express 2008, however the example can only open and save .pic files! How can I make it so that my application can open and save a commonly used image type, such as bmp, jpeg or png? I would imagine it can't be that hard, just saving what has been drawn in the picturebox into an image file, or loading an image into the picturebox.
I have tried to make a load event by using some simple code I've made: If OpenFileDialog1.ShowDialog() = DialogResult.OK Then PictureBox1.Image = Image.FromFile(OpenFileDialog1.FileName) If Not (PictureBox1.Image Is Nothing) Then m_Picture = Nothing PictureBox1.Invalidate() [Code] .....
When I simply delete this section of code, pictures open fine however of course then I cannot draw, which defeats the purpose of my application. So how can I open and save images with my paint app?
[url]... I managed to figure out how to paint a bitmap on a form. With some slight modification, I managed to make it so that the position of the bitmap can change based on key strokes.However, for some reason, it only does this once. It can't be that the xPosition and yPosition aren't responding since I rigged two labels to tell me their values and they are changing. So how can I make the bitmap respond.[code]...
I am making a screenshot saver/viewer and I want to be able to click on the PictureBox1 when it has an image inside it, and have it open up "mspaint.exe" and paste the contents of the PictureBox1 Image into Paint. How can I do this? [code]
I have a MonthCalendar control on a panel and it is invisible; when the user clicks on a button I make the panel visible which is fine but the calendar control selected date is highlighted half on one date and half on the other.
Why is this happening? If I simply show the control it does this.
Whenever I load or close child forms or other form (for that matter) then there is flickering in my MDI form. The flickering maybe because the form may be getting painted with gradient or so. Now this flickering is really noticable and I need to solve this. I am pasting the code that I am using to paint my MDI form. If you guys think the code is in efficient then let me know. Or if there is any fix or other way to go about it then I would like to know.
CODE - written inside my MDI form.
Public Class MdiContainer Inherits Control Private WithEvents MdiPane As Control
I am having a windows form that whenever I want its controls like picturebox update normally I need to hide it and show it to let the cahnges happen. This causes a blink which I want to avoid.

I am currently working on my own listview control, and I was wondering if it was possible to get it to not draw the text for the listviewitem when the listview is in report mode? What I have been doing is putting all of my information in the tag and leaving the text property blank so it doesn't paint. Andis there a way to paint the background of the column headers? Because It only allows me to paint the actual column header? Here is what im talking about for the background of the column headers.
I want to create a track bar using paint event, but the problem is on mouse move event<Me.Invalidate()> is very slow since the graphic become unvisible for milli seconds and then return back, is there a way to make it faster?(doesn't become invisible)
