Just need a good direction to retreive the 10 color palette of a bitmap.
I have the following code:
foreach (Color color in new ColorConverter().GetStandardValues())
{
output.Write(color.ToString());
}
What would be the syntax to get it to show as a color palette instead of just listing the colors?

I have created an aspx page that is displaying user profiles, and on that page I have an asp.net image control that I dynamically populate at runtime based on the users profile image.
I have created several themes, just modifying css to display the profiles with different background and different layouts.
For fun I have created one theme that is kind of like the matrix, and I would like to be able to take the users profile image and change it to a 'green scale' so to speak, or even just a straight up green color, more so this one #20f380. The profile images are just jpg, and are already cartoonish so they should change to green without the image looking to bad.
Is there a way to use code behind to change an image's colors?
C# or VB is fine, currently I've not been able to find any tutorials that work for me, or are close to what I am trying to do.

View 1 RepliesI have a class (let's call it Car) that has a property of type System.Drawing.Color (Call it CarColor). I have a script service function that uses this Car class as a return value, which works just fine. I then have another script service function that takes a Car object as a parameter. I would like to change the color of the car in Javascript, but I am finding it difficult to do so without adding another parameter that takes in the color as a string and is then translated at the server. Are there any ideas on how to set the Color property of the Car object in Javascript and maintain it through to the server?

1) I notice that the module gets it's data in chunks. This is problematic for me because I'm using a regex to find and replace. If I get a partial match in one chunk and the rest of the match in the second, it will not work. Is there any way to get the entire response before I do my thing to it? I have seen code where it appends data to a string builder until it uses a matches on an "" end tag but my code must work for more that just (xml, custom tags, etc). I don't know how to detect the End Of Stream or if that is even possible.

I have been developing a quiz application in asp.net mvc. In this quiz user is give a list of topic to take quiz. On click of one of the topic the user is taken to new page. In the get part action of this page i have taken some parameters, generated questions for the quiz, register quiz for the user (save in db)and save the generated questions in db.
Now the problem is:
User see the page, if user hits the "submit" button after selecting the answer than it is ok but If user refresh the page. Then the get action is called again and new set of questions are generated and new quiz is registered to user.
How can i avoid this?
Is there any way to detect that the get action is called the second time or to detect page refresh in as.net mvc.
If you could suggest design changes that it is ok too? i just need to make sure if user refresh the page the question need not be generated again and new quiz should not be registered to user.
I have a sitemappath that I want to surpress on the home page of a website. Assuming the homepage is "www.mysite.com/default.aspx", what is the best way to detect when the base URL is being displayed?
IOW: I can do something like:
if request.servervariables("url") = "/default.aspx" then
sitemappath1.visible=false
end if
but how do I detect when the default url is being used, like:
www.mysite.com
without a page url at the end?
