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 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.

View 1 RepliesI currently have the following code but I would like to get away from going to a physical location. If I have the icon as a resource, how can I programatically add the icon? I don't want to use the form's designer to do this.

Dim ico As New System.Drawing.Icon("C:Resourcesicon.ico")
Me.Icon = ico
End Sub
My application icon looks ugly-like a paper and i would like to change it to something like globe icon or any suitable image.Am programming using visual studio 2005 and the program is written in vb.net.
View 1 RepliesI'm not sure exactly if the folder icon is in shell32.dll, but nonetheless if it is.Basically, whenever I come across a folder in a FileSystem list, I want to add the icon for a folder to the image list that I am using for the ListView. The problem is that I'm not sure how to reference a specific icon location in a icon collection in a dll.Is this possible with Icon.ExtractAssociatedIcon and shell32.dll?
View 14 RepliesGot an annoying issue it's Visual Basic 2010 I changed icon where the assembly name.I got a good icon it has lots of sizes, or I tried diff sizes like 64x64 128x128 nothing seems to work I only see the icon when i do View > Details so it's small icons in the folder, but if i have view large icons It doesn't work. I even used the same icon on VS 2008 and it worked.
View 1 RepliesHere's the code that I use to extract the icon size that I want:
Dim i As Icon = My.Resources.Spectrum
Using i2 As New Icon(i, New Size(256, 256))
Me.PictureBox1.Image = i2.ToBitmap
End Using
This works from 16x16 up to 128x128 but for 256x256 it extracts the 128x128 icon. I tried 0x0, because I seem to remember that that is how the large size is stored in the meta data, but that didn't work either.
I'm attempting to remake the Explorer to customize it some more. I know how to get Name, FileSize ect. Getting the Icon is hard though.

The code i'm using to Insert the Icon into a image, i'm getting this error: Error1Value of type 'System. Drawing.Icon' cannot be converted to 'System.Drawing.Image'
i'm getting this really strange error, or I must be overlooking something obvious. I'm using the following piece of code:Dim hwnd As Integer = GetWindow(GetDesktopWindow, GW_ CHILD) Dim myicon.As System.Drawing.Icon =Icon.FromHandle(hwnd)PictureBox1.Image =myicon.ToBitmap

Why is it that the icon of my form appears only when I am running it in my IDE. When I publish my program and running it in Windows, the icon does not appear at the taskbar, what appears is a default icon instead.

It works perfectly for files on the local system. But i need it to also grab icons from exe files in network locations(\\example-pc\example). Vb net just throws an error when trying....The error:QuoteValue of "\\examaple-pc\example-folder\example-file.exe" is not valid for 'filepath'.
Im trying to make the an icon for the form work with my own icon, because all programs have their own(like ie hat the e and paint.net has their logo), but whenever I put in my icon phote(and it is saved as .Ico) it comes up with the error: Argument 'picture' must be a picture that can be used as an icon. I have the same measurments as the defult one(32 by 32) so what am i doing wrong?

I'm trying to create thumbnail previews within my program. These would work for any file type, not only images. So videos too. Right now I'm using IExtractImage to do this. It works perfect, but it seems to randomly crash my program when I call .Extract(). There's no error message, my program just crashes. When I run it in the debugger it doesn't break when it crashes. I have it in a try/catch block and that doesn't seem to help. It's not reproducible and doesn't crash on the same file every time. How can I get it working or just prevent it from crashing my whole program?

View 1 RepliesI am trying to get this code to re-size(by a percent) the pdf thumbnail it outputs(which needs to be initially scaled down to 15% of the size of the original pdf document size).Currently, the code only adds the two dimensions as pixels, then renders the image, and draws it into a PictureBox.The code uses Ghostscript as you can see. The problem I am having is getting the dimensions of the PDF file. How can this be done? The code will be posted below:

ve been exploring with IThumbnailProvider in VB10. The first attempt I made was to handle MKV file thumbnails. I made the library and everything looked OK when I tested it against MS's Thumbnail app that came in the Windows API pack. Then I attempted to implement it on my computer, and every single thumbnail in the OS broke. Not a single thumbnail was generated by the system. So, after a bunch of trying to rescue thumbnails, I reformatted, reinstalled Windows, and got everything back to normal.
Today, I tried again. This time, using BLP files which are often used in Blizzard games (Warcraft III in particular). To avoid the same issue, I threw the compiled result into a Virtual Machine and tested it there, and it looked lovely. After a bit of experimenting and tweaking, I got it exactly as I wanted, cleaned the thumbnail cache, tested it one last time, and then installed it on my actual PC. Bam, all thumbnail generation is broken again.
I am in search of a way to access a files thumbnail preview and push it to a picturebox on my form. I have the code below that works for jpg files, however it does not work for say a word document's thubnail. displaying the word documents thumbnail in a picturebox would be great!
Dim myBitmap As New Bitmap("C:Doc1.doc", True)
Dim myThumbnail As Image = myBitmap.GetThumbnailImage(40, 40, myCallback, IntPtr.Zero)

I am writing a Windows Service to act as an internal Web image collector. I can thumbnail Web navigated to webpages using a webBrowser Control. But since a Service will not support a UI based Control like a WebBrowser control I have switched gears using the wrapper WebClient from system.net. So I am looking for a way to capture and thumbnail a Webpage.I can use the following to grab images off a web pager using webClient but cannot figure out how to thumbnail the entire page.
Dim imgBuffer() As Byte Using wclient As New WebClient() imgBuffer = wclient.DownloadData("http:// Webpage/Image") End Using
Using mem As New IO.MemoryStream(imgBuffer) Using img As Image = Image.FromStream(mem) Me.PictureBox1.Image = img.GetThumbnailImage(100, 100, Nothing, IntPtr.Zero) End Using End Using
