Thumbnail View In OpenFileDialog / SaveFileDialog?
Jan 25, 2008
Having searched long and hard I came up with nothing to solve this problem.It appears that no body could give me any direction on how to default an Open Dialog box to what ever view type I desired.It was after several fruitless hours that I changed my way of thinking and started to look if this had been accomplished in any other language other than VB.that is when I stumbled on some code in C# written by Robert Rohde (German I think the original code can be found at [url]I have rewritten his code to be VB2005 compliant and It works a treat, so for all those (who like me) couldnt find how to complete this very simple yet so difficult to achieve task I present the code put this first section into a class called FileDialogExtender

My users need to browse to select a file and then save it to a different location. Here's my code I've got so far - it incorporates the OpenFileDialog to open the file and the SaveFileDialog to save the file. When the code goes into the OpenFileDialog portion, it works great....the initial directory is set to "C:" This is where the user will select the file they want to save to another location.

Is there a way to override/modify/create the left-side shortcut buttons in the SaveFileDialog or OpenFileDialog controls? Defaults are "My Recent Documents", "Desktop", "My Documents", "My Computer", "My Network"... how would I change "My Recent Documents" to "My Super Cool Folder"?

I have files that start with unique numbers and are word documents. Say the document starts with "1234567" is there a way to make the OpenFileDialog filter to where only all the .doc files that start with "1234567" show up?

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'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?
I'm using the code from this project:[URl]..

I 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:

Imports System.Drawing.Imaging
Imports GhostscriptSharp

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 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
End Sub

The preview on my program doesn't show how I would like it to, sometimes it's blank or not big enough for the whole screen, and other things.
I have 3 forms, one is of controls, one is a full transparent form that is just the outside edges with a blank middle, and one of is the background. Reason for this is setting background transparency, and the transparency(opacity) of the top bar of the form, so it will be transparent like vista is normally in xp.
I want it to show always the full form live view on the preview and I am not getting it to work with my 3 form as one form type program, but it works as expected with one form only, but I don't want this because I want individually set transparencies.

Is it possible to set the image windows displays when viewing a file created in a VB.NET application? In my case I have files saved that store info on football plays for a play creator program. Can I use the image of that play as what the user will see when he searches through windows explorer?
Let me further explain with an analogy: photo files in windows have their images displayed as the user cycles through them; he chooses which one he wants to doubleclick based on the thumbnail image of the actual photo. I'd like to have a "photo" of the play itself shown instead of what is now just a blank generic grey icon for the play files that I save.

This code works on my local machine (Windows 7 Ultimate).When I tried it on WindowsXP,it didn't even open the dialog,instead it gave me an Unhandeled Exception error.
I can't remember the specific details of the error,but I do recall my profesor telling me there could be something wrong with permissions(me being the ONLY user on my machine,and his machine having multiple user accounts).
But what does all that have to do with opening the SaveFileDialog?
Could it be that SaveFileDialog1.AutoUpgradeEnabled = True is causing the problem?

I have an .net 1.1 framework application I would like to update to 3.0 framework (or at least 2.0), but I've just run into a real problem. The savefile dialog code which works fine in 1.1 does not work in 2.0 and up. Line for line the code is the same (thereis no difference in line numbers at all). I'm baffled.With the exception of throwing an error for the Quicktime 7 control, VS2008 indicated no errors in converting 1.1I open my 1.1 (VS 2003) version and step through line-by-line. Works as advertised.I open my 2.0 (VS 2008) version and step through line-by-line. Appears to be working, dialog opens fine, I enter a filename, code continues; but when complete, there is no file in the folder.I'm wondering if the problem lies in the block of code for the small XML file I'm writing.
