C# - How To Create IPhone Style Icon Effect On Thumbnail Image
Oct 23, 2009
I have an image upload facility in my asp.net project, when uploaded a thumbnail of the image is generated and saved to disk. What I would ideally like to do is apply some nice styling effects to this thumbnail image.. similar to the look of the icons on an iPhone.. perhaps a slight gradient, smooth rounded corners, and a border.

I have some code that allows the user to browse for an image and then when that image is opened, it is copied to a new directory. This all works fine, but I would like to know if there is a way to create a thumbnail of this image and save it into a subdirectory inside the directory where the original image has already been copied?

I want to use the ExtractAssociatedIcon method to get the icon of a bitmap.
But in MSDN I found the following statement:
When ExtractAssociatedIcon is used with bitmaps, a thumbnail image may be returned instead of an icon if the system that is running the application has a registry setting that causes bitmap files to be shown as thumbnail images.
Is it possible to turn off the thumbnail and get the icon back?

I have a system where users can upload PDF documents. Rather than displaying the link to these PDFs as a title link, or a PDF icon link, I would like it to be a thumbnail of the first page of the PDF document.
How can I get a thumbnail image of the first (or any specified) page of a PDF document, using ASP.NET 3.5?

I am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.

I've been playing around with Windows 7 taskbar thumbnail previews. I've noticed that some Microsoft applications are able to set thumbnail images which have transparency in background. I've been trying all out and not been able to achieve this.
I've set a picturebox control having PNG with transparency as thumbnail preview, doesnt work. I tried creating a new bitmap and loading from Icon file having transparency and setting it as preview but still doesn't work. It keeps showing the background color of the form window.
This is what Microsoft apps are able to acheive:

Is there anyway to save a thumbnail of an image, then save it so that, when viewed through My Computer, the thumbnail is displayed for the file. Basically, what I mean is to do something similar to the way you can see a preview of a pdf file, or Microsoft Word file, or Microsoft Expression Design file. I want to be able to open the file's containing folder, then switch to thumbnail view, and the thumbnail will be displayed as the image for the file.

I have a vb.net 2008 application which has its corresponding icon.
The icon shows correctly except in the taskbar when the "small icon" setting is on.
My vb.net project includes a .ico file which when I see in the IDE includes 16x16, 32x32, 48x48, 64x64 and 256x256 bitmaps, in 4, 24 and 32 bits, also 3 .png images in 256x256 32 bits each.
I made the icon myself simply using a 64x64 bitmap and then converting it to .ico, and assigning it to the application in the project properties. I thought windows would use and escalate the corresponding image, it shows even in the file explorer properly in the small icon form, but not in the taskbar.

I have a picturebox and I have a image with a blue and red square. When I click a button it puts that image into the picturebox as background image. The background image property is set to tile. But when I click on my form to draw the image to it, it just draws the original not the one that has the tile effect from the picturebox. Is there a way i can do this to keep the tile effect?

I am currently painting a light blue, partly transparent overlay over owner-drawn objects to indicate certain state. It's OK but I thought that it would be even nicer if I could at some sort of glass effect to further establish the idea that the particular object has "something" overlaid over the top of it.
I thought that some glass streaks, for example, in addition to the blue transparency would lend a nice effect.I've Googled around for GDI+ (and others) algorithms to do simple things painting like this but have come up empty. I prefer .NET but can figure out the painting from pseudo-code on up.
Sorry, shoul've also specified that I need to target WinXP and using .NET version 2.0 - So unable to use WPF or Vista/Win7 goodies.

I'm trying to replicate the Gmail Notifier popup.It both fades in (Opacity) and raises from the start bar.
I've managed to do the fade inout using a timer and opacity but how do I:
A) make the form appear to 'pop up'? (I think its height grows via a timer from 0 to it's max?
B) Locate it's start point exactly above the task bar as pictured on all screen resolutionsWindows flavours?
