Is there a way to use the firefox (or chrome or any other good browsers) rendering engine to convert html (as a text string) to an image?I have full access to the server I'm using, so no limitations there.
View 2 RepliesMy Asp.Net calls a SQL sproc and returns a XML file as a string. This is what I need to do:
- save that string into memory (as a file);
- pop up a dialog box asking the user which path he would like to save the file;
Any samples out there...how do I achieve this task in Asp.Net C#?
I am using the following code to write the contents of a string (converted to a byte array) to the client in ASP.NET/C#
byte[] data = StrToByteArray(strData);
Response.ClearContent();
Response.AppendHeader("content-length", data.Length.ToString());
Response.ContentType = "text/plain";
Response.AppendHeader("content-Disposition", "attachment;filename=" + fileName);
Response.BinaryWrite(data);
Response.Flush();
fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?
Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?

We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
View 2 Repliesanyone knows how to replace a html tag in a string with specific characters:
e.g.
string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";
i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.
i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.
I have a form where users can store some data for archived documents. All documents are ONLY in PDF format.
There are 2 things I would like to do:
1. there is a "file path" text box on the form. I would like to open a "browse file dialog" box when user clicks the textbox and then the user browses for the file (file is on the users local machine) and selects it. The full file path should be saved to the textbox as string (e.g. "c:archive2010document11122011.pdf"). Also I would like to "limit" the file browser dialog to only show PDF format files...
2. add a code behind command to open the file from the saved path+name (see 1.) in the user's default PDF viewer (Acrobat or Foxit)
<%= Html.RouteLink(">>>", new { page = (Model.PageIndex + 1) },null)%>
Is it possible to set image instead ">>>" and how?
I want my users to upload their photos to my website. I am using fileupload for this. I have jquery to crop the image to desired size ( according to user).What I am doing is this, when a user uploads a photo, I use the uploaded image's address as ImageUrl , and the user gets its pic dynamically as soon as he uploads it.And then with the help of jquery , user can crop it to dimension of his/her choice. Finally, I get a cropped and smaller image. [:)]But the real problem is this, if a user uploads a picture of greater dimensions ( e.g. 1600x1200) , image covers up all the screen, so I want a method so that the uploaded image get restricted to a fixed height and width (say 500x5500) before it is available for cropping to the user.I have tried .......,Image's Width=500, Height = 500 ( using asp:image ) and attribute.add.style("width:500;height:500); ( using html img ) in code behind after uploading image . The image first appears in 500x500 dimension but immediately changes to its original dimension...

View 1 RepliesI've got an ASP.Net app that uses Jquery ajax to get dynamic html an insert into a certain div on the screen. This works but one of the tags is an image tag and no image is being displayed, just the "X" since image is on the server. The path of the image is on the server, ~/Images/user2.png.
I'm thinking about having a server side image, , hold the image i need that is not visible and somehow using jquery, "copy" that image to the real html image tag after it is appended.
But I can't think of how to copy it.
The thing to remember is the html image tag doesn't exist until the ajax data is loaded and appended to the destination tag.
