I have the following .ashx page that takes some query string parameters and returns a bitmap with the specified text written on it. The problem I have is that I am currently just manually setting the initial size of the bitmap at 100 X 100 when what I really want is to have the bitmap be just big enough to include all the text that was written to it. How can I do this?

I am working on a website that draws fractals on the screen. It was my intention that with a right mouse click the picture could be saved to the visitor's computer. But that I get an error message "filetype blocked".The file is called test.jpg and is drawn to the screen as a bitmap. Could anybody tell me how to 'unblock' the right mouse click so that a visitor can save a picture he or she likes?Maybe it would be possible to let people download the image? But how would that work?

I want to embed a silverlight app into a web page and have the height/width of the div that contains the silverlight control match the dimensions of the actual size of the silverlight control.
I essentially want the div to stretch to accommodate the size of the silverlight control. I do not know what size the silverlight control will be before it loads as it is pulling in data and adding controls dynamically. I want to avoid dueling scroll bars and use only the browser scroll bars.
I need this to work in both IE and Firefox.Is there a way to accomplish this?
I am currently dynamically creating a bitmap and using the graphics object from the string from the bitmap to Draw a string on it like so.
System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp);
graph.DrawString(text, font, brush, new System.Drawing.Point(0, 0));
This returns a rectangle shaped bitmap with the string written straight across from left to right. I would like to also be able to draw the string in the shape of a rainbow. How can I do this?
I'd like to add a description field to an application that can be as long as several lines (or even paragraphs) or as short as a one-liner.Instead of taking up a lot of screen real estate or have scroll bars, it would be preferable to have the textbox grow based on its input.
On IE6 adding Style="overflow-y:visible" accomplishes this nicely (both on display of read only, and if we are in edit mode).
However, it has no effect on Firefox, or IE7 for that matter.
I´ll try to describe the problem in steps, as this might be the easiest to understand:
1. Page_Load is called when the page is requested, and calls a BuildTable() method
2. The BuildTable method creates a table which contains several textboxes
3. the user types some text in these textboxes
4. The userthen changes an item in a Dropdownlist on the page which is intended to change some other content on the page
5. Page_Load is called, and afterwards the DropDownListBookingType_SelectedIndexChanged(object sender,EventArgs e) method are called, and the content is changed
6. The text the user typed in the programmatically created textbox controls are lost!
Now how do I remain this text information? If just the SelectedIndex_changed method was called first, I could save it in session.. But as far as I can tell, all data on the page are discarded when you create a partial postback :(
How do I restrict the number of input fields in the form to match the size of the columns? Table Columns Reads:
state: Type Char; Length: 2
zip: Type: char; Length: 5
Phone: Type: char; Length: 12
Fax: Type: char; Length: 12
Email: Type: nvarchar; Length: 256

I have a colorpicker.png file and track the pixel clicked in codebehind using GetPixel. Works like a charm, but I read that converting to a bitmap on the fly is rather heavy on the server. Therefore I saved my .png file as a .bmp as well, so that a converted file would already exist. However, I don't seem tobe able to just use the bitmap file, but need to create a new bitmap from the bitmap...
My question is: The code below works (I provide it here for those who might need it - simply add the code below to codebehind and this code in your aspx page <asp:ImageButton
ID="cpRubrik"
runat="server"
ImageUrl="~/img/colorpicker.png"
/> ;
also note that the image can be whatever you want - a photo or a screendump of a colorpicker from say Photoshop or VS; and note that it's wise to put everything you need in an updatepanel). Should I write something else in order to get smarter access to the bitmap?
Protected Sub cpRubrik_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles cpRubrik.Click
tbUtseenderub.ForeColor = BytFarg(e.X, e.Y)
End Sub
Protected Function BytFarg(ByVal x As Integer, ByVal y As Integer) As Color
Dim myBitmap As New Bitmap(Server.MapPath("~/img/colorpicker.bmp"))
Dim clr As Color = myBitmap.GetPixel(x, y)
Return clr
End Function
Background: I've wrote a small library that is able to create asp.net controls from a string.

I've expanded the code with some reflection to gain full flexibility to be able to render WebControls and UserControls. Works fine so far, for every usercontrol I've tested. I'm now facing the problem, that the parsing for my property key-value is not flexible enough to support arbitrary multine content.
This is part of the code that I'm using for the string operations:

My admin set innodb_buffer_pool_size=512M, innodb_log_file_size=128M, and innodb_log_buffer_size=1M although in mysql query show global variables its showing what the value is set. When i restart my system also its showing what we set the data.(It means we set log file buffer file size to max and its working fine.) but when i try to upload a file of 58 mb again its throwing error as The size of BLOB/TEXT data inserted in one transaction is greater than 10% of redo log size.
View 1 RepliesJust wondering if it is possible to programatically highlight all the text within a textbox.
Specifically, I have a text box with validation. If an error is thrown, I set the focus to the specified textbox, but the way it works now the user starts typing and none of the text that already exists disappears. I'm wondering if I can make it so that if the error is thrown, not only is the focus set to the textbox, but the text within the textbox is selected, so that if they simply start typing all of the old text disappears, or they can click and retype a single character if necessary.
I'm currently building an intranet engine for a project I've got on the go at the moment, and I'd like to save myself a little time by generating header images from code where possible, however, I'd like it to match our concept image.What I'd like to achieve is below:My issue is I've not the faintest how to create that from code. I can do the absolute basics but that's about it.
I start to fall down when it comes to the gradient background and the drop shadow on the text. I can get away with positioning the text on the larger header image, so if it's not possible to generate the exact gradient I have there, then I have a work around for that, but what I really want to achieve is the text with the font and drop shadow.I'd say it's safe to assume that to use a "non-standard" font, I'd merely need to install it on the web server?
I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.

View 2 RepliesHow do i set the size of the tooltip dialog box. the tooltip text must be displayed in one line rather than wrapping the text to other line.
in firefox and IE7 tooltip text is showed in one line but in IE8 the tooltip text is wrapped . i.e text is displayed in 2 lines.
asp:Image runat="server" ID="iUrl" Visible="false" ImageUrl="~/Widgets/FMP_Printers/images/status icons/icon_Fault_Enabled.gif" />
if (txtUrl.Text.ToUpper().IndexOf("HTTP://") < 0 && txtUrl.Text.ToUpper().IndexOf("HTTPS://") < 0)

I'm developing a web form. I use the style sheet for the page and make the font size x-small.
But I noticed all the text boxes in the page looks a little higher than expected comparing with the font of the other text in the page.
Is there an easy way to change all the height of the textboxes on the page? and make new creation of text boxes the same height as all the other controls on the page?
Also I tried to select multiple text boxes to aligh them or make the same size, I remember I can do it in visual studio 2005 before, but now I cannot do it in 2008.
I did it be select one, and press ctrl button to select the other one, but the other one cannot be selected. Did I do something wrong?

I'm getting this message when going to a web app that accesses my service.
"The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8)..."
The thing is, it happens once in a while even when no changes have been made to the service or the web app. And I can make it go away most of the time by going directly to the .svc?wsdl page in my browser and then coming back to the web app.
