I am looking for a solution (APIs, etc.) for handling a similar experience as cafepress.com. I need to be able to upload images (preferably multiple at a time) and be able to map my uploaded images to various product images (clean stock images of shirts, mugs, etc.). I also want to give the user some very basic controls over the images they upload such as cropping, resizing, levels, etc. Any suggested libraries or APIs would be greatly appreciated. I am looking for .NET solutions (if server-side). I am not looking for how to tie this all together but rather some suggested libraries or tools to build out some of this functionality.
Note: If this is not the place for this type of question, please move accordingly or suggest an alternate site.
Frankly, I don't think you are going to find what you are looking for specifically, unless you are looking at using a full on CMS of some form. Frankly, those problem domains are too far apart. Instead you should probably look at them as individual pieces.
So far as upload controls exist, there are probably close to 100, some free some not so free. Personally, I already have a Telerik subscription, so it was a no-brainer for me, but Rad Upload works well and supports multiple uploads. Free implementations are available.
The cropping and post image handling tasks ( at least the ones you have listed ), can easily be handled using standard System.Drawing.* calls, or if it gets more advanced a ton of free libraries exist, like the age old ImageMagick, but there are a number of commerical libraries available as well. Chances are though, the inbuilt libraries will be more than sufficient.
Finally the mapping to products should be handled by your business layer ( aka, code you write ) as it is going to be so specific to your app.
However, if you are looking for a storefront or CMM with a multiple image upload control, that is a very different question with many options as well, both free and commercial.
use openCV. you can find it here: http://opencv.willowgarage.com/wiki/
you can use this library perfectly with c++.
if you need to use it in C# use this wrapper: www.emgu.com/wiki/index.php/Main_Page

Is there a code to get all the image editing software the user has installed?
I would like to know how to list all the applications by going through registry, is there any way to then filter out only the apps that can edit images, like Paint, Photoshop, etc...?
Thanks!
Here is an example for any generic file type:
How to get recommended programs associated with file extension in C#
If you look for jpg, png, etc. you'll get image editors.
No.
There is no expectation that every application developer somehow places metadata tags for their application inside of the registry (or wherever)... and, if for some reaosn a few handful of application developers did there is no way to guarantee the consistancy. Not to mention that application developers don't always use the common words you'd expect for their applications... Not every image editing application has the word "Photo" in it (for example, Picasa from Google).
The best you can hope for is to build some keywords to look for, add in a list of famous applications that don't conform to the keyword conventions your expecting ("Paint", "Photo", "Image", etc.), and work with that... either that or create a large database yourself to check against. Also, as other answers/comments have indicated, looking for applications that are used for specific extensions is helpful.
Nothing guaranteed though.
I need to get information from couple of web sites . For example this site
What would be the best way to get all the links from the page so that the information could be extracted.
Some times need to click on a link to get other links inside that.
I tried Watin and I tried doing the same from within Excel 2007 with Web Data option.
Could you please suggest some better way which I am not aware of .
Ncrawler might be very useful for the deep level crawling . You could also set the MaxCrawlDepth for specifying the same.
Have a look at WGet. It is an incredibly powerful tool for mining the content of a single page or an entire website. The options available allow you to dictate how many levels deep to follow in terms of links, what to do with static resources such as images, how to handle relative links, etc. It also does a very good job of mining pages which are generated dynamically, such as those served by CGI or ASP.
It's been around for many years in the 'nix world but executables compiled for Windows are readily available.
You would need to kick it off from .NET using Process.Start but you could then pipe the results into multiple files (which mimic the original website structure), a single file, or into memory by capturing standard output. Then you can do subsequent analysis such as extracting HREF HTML elements (if it is only links you are interested in) or grabbing the sort of table data evident in the link you provide in your question.
I realise this is not a 'pure' .NET solution but the power WGET offers more than compensates for this, in my opinion. I have used it myself in the past, in this way, for exactly the sort of thing I think you are trying to do.
I recommend to use http://watin.org/. This is much simpler than wget :-)
I am developing a ASP.NET web site where users will need to be able to create their own business cards. So, I'm looking for a tool (most likely Flash) that I can easily integrate into a web site and lets users add text and custom images to their cards and then create an image and/or PDF from their work.
is there a plugin that does this?
If you write your own business-card creator in flash, you can save the view to PDF files using AlivePDF.
You could have a look at this: http://www.shirtnetwork.com/en
It is less of a plugin and much more of a fully customizable software solution, with an administration backend, PDF export, billing etc. . I worked on the client and I must say it is a very mature and potent software and probably can do about anything you want, when it comes to customizing products. I don't know, whether you like the pricing model, OTOH to my knowledge, they also provide provision-free licences.
I don't know, whether there are reasonbly expensive components available, that do this for you, because you can get a load of money out of this business, so I wouldn't expect anyone to give them away for free.

We are looking for some code/component that can create a flow-chart (image) dynamically, preferably in .NET/C# (although a Silverlight/Flash-component that takes a XML/JSON-feed will also be fine).
For example we have a (business) quote that goes through te following steps before it becomes final:
Requested -> Pending -> Ready for revision -> Under revision -> Final
And as an extra step there is the possibility to go from 'Under revision' back to 'Pending'.
So the component/code should draw something like this (where 'Under revision' would be the active status for this quote):
Example chart http://www.wowtah.nl/flowchart-example.gif
The reason that we are not just creating static GIF-images (and load the correct one on demand) is that these steps can vary per customer implementation of our product. So we're looking for a way of dynamically show the user the workflow steps that are configured for them.
Any help would be greatly appreciated!
Take a look at Microsoft MSAGL
I built a workflow solution a while back and evaluated a number of diagramming controls, including the MindFusion control. I settled on the Syncfusion diagram control, primarily for its ease of use for an end user (especially when drawing connections).
I'm using the WPF edition, but they make editions for ASP.Net and WinForms. It has methods for exporting to images.
These are some of the components that I can remember evaluating; I'd recommend giving them a shot and seeing which you like best.

MindFusion looks like they have some good diagramming controls that may work for you:

In the meantime there are also open source diagramming libraries that you can find on Codeplex and Google code.
A very deep one with many features and very flexible is

Perhaps easier to program but more limited in scope

I have a project that has a list of gps coordinates. I would like to find a way to make a simple map of those coordinates (possibly just one at a time). The map should have basic street info.
This part of our project is pretty simple so I don't think it needs to be an exceptionally feature rich product. This also means it shouldn't be really expensive.
What is a good product to achieve this?
edit: This is a desktop app where internet connectivity will probably not be available.
Google Maps is great for this.
If this is a desktop app with internet access you could still host an IE control and show it there.
EDIT: If this is a desktop app without internet access you'll have to buy something like Microsoft Streets & Trips. I don't know if it has reusable controls. You probably have to buy something more expensive to get that. Applications of this nature often fall under the category "GIS". Try searching Google for that.
Sharpmap is open source project written in C# and released under LGPL. To quote first line from page:
SharpMap is an easy-to-use mapping library for use in web and desktop applications.
I'd go with this solution
Map Rendering: SharpMap
Geometry operations: NetTopologySuite
Map data store: shapefiles in your file system or PostGis over PostgreSQL
Map data itself: the easiest way may be extracting from OpenStreetMaps data. Here, for example you can download shapefiles for your desired location
Everyting is open source (more or less, check the licenses) and works fine on windows.
Hope it helps
ESRI has an API. They have javascript, silverlight,wpf, and flash. they may have more. ESRI is pretty much the standard in mapping.
