Do you think the following one is best for adjusting Contrast level? In fact, I would like to get the same/close perfromance for adjusting contrast as found in Photoshop.
public static Bitmap AdjustContrast(Bitmap Image, float Value)
{
Value = (100.0f + Value) / 100.0f;

View 1 RepliesI have a page which displays details and a pictures of employees. The details are stored in a SQL database and the images are on the server. How can I set a default Image to display (e.g. an Image saying "Awaiting Image") if an employee picture is missing?
I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

View 1 RepliesI'm using the following JavaScript function to hide images on my webpage in the event that the source image is not found:
function Image_OnError(image) {
image.onerror = "";
image.style.visibility = "hidden";
return true;
}
I add the following attribute to my images which calls the above method in the event of an error onerror="Image_OnError(this);".
The problem is that I need to do the same for <input type="image" /> elements but can't figure out how to do this as the input element doesn't appear to have an OnError event. I could just include an extra image with the same src value as the input and then modify the visibility of the input element on the image's OnError event, but this seems a bit messy.
i have added an new chart (data from acces database, looks like that:
1 2
123 123
333 222 etc).
No errors, no exceptions, but i realy cant see image ;-)
when Im trying to righht-click on chart in my browser and choose "show image" i get :
System.ArgumentException: The image is not found.
I have a problem with my chart image not refreshing and I narrowed it down to the fact that there's an unrelated image that according to MS VS2005 IDE, that the image file is not found... BUT..when I run/debug it... it displays properly.The image is right in the root of the aspx directory so it is not in any folder.<img src="right-thumb.png"> // this works but ide shows error and causes chart to have update problemi get an error in the IDE file is not found. however, if I display a FULL PATH, the problem goes away. WHY? i don't want to display the whole path because i don't want public users to see the server file location.
<img src="c:webapplication
ight-thumb.png"> // this works for everything
i also tried
<asp:image runat="server" id="Image2" ImageUrl="~
ight-thumb.png" />
and that too also has a problem! It underlines in red and says teh file is not there, but when i debug, of course it works and the image loads....

This is the SQL statement I have the chart configured too:
SELECT [ConfidenceLevel], [LoveLevel],
[DateTime], [StressLevel] FROM
[UserData]
My issue is in cases like this example, the data recorded around 12/4 looses it's fidelity and is un - "see able", it all blends together.
How can I configure the chart so that the last 20 days are always readable on the chart and that they don't blur together?

View 1 RepliesI am writing our file to a web page, and have already figured out how to change the target of an iFrame when one of the Treeview's nodes is clicked so that the user is taken to the correct page of the file (mixture of javascript and treview properties).
What I can't figure out is how to adjust the treeview control when the user clicks on a link in the target page and is taken to a different file page. Absent any other action, the treeview control would still show the wrong node as being selected after the page is selected.

I'm now facing the problem, that the parsing for my property key-value is not flexible enough to support arbitrary multine content.

I'm working on a ASP.Net web page with two tables positioned in the center of the page with one on top of the other. The table on top contains input fields that are dynamically generated by the code-behind, so the number of input fields varies. The table on the bottom contains content that is constant and doesn't change. The layout of the page is fixed and must remain so. My question is, how do I make the bottom table dynamically adjust vertically so that it doesn't overlap with the fields from the top table. The general HTML layout of the page is something like the following:
[code]...
I'm thinking I could wrap the bottom table in a div, but I'm not sure what specific styling will achieve the desired effect. I basically want to maintain the fixed positioning horizontally, but have the vertical alignment adjust to prevent overlap with the top.
UPDATE:
Here is a screen cap that shows the two tables overlapping. The buttons you see are in the bottom table, the fields are supposed to be on the top, all elements are positioned absolutely in the center of the browser screen.
UPDATE 2:
I updated the HTML sample above with the styles that are currently in use.
