I have three values that are being generated dynamically in the code-behind of my web form. These three values will be shown to the user. While this may sound odd, I do NOT want the user to be able to copy and paste these values. Because of this, I would like to write out the values via an image that is build dynamically.
My question is, is there a way to dynamically create an image and write it out to the response? I would prefer not to create an image, save it to the server, and then pass a url back to the page. I would really like to write out the binary content along with the response.
i'm using stream writer to write a text file on client machine, but everytime while i'm writing a new file it over writes the existing one..so now i need to write seperate file each time ...and also i need to create a folder dynamically for first time and save text files in that folder when everytime i use my application....
I have write small web-service that recieves query and read txt file for matching. For it I'm using StreamReader.
I'm not waiting that it will be thousands of users in hour for this service, but whats worried me - if some users at the same time will be use that service is it ok? Can text file on server side be readed at same time from some users?
What is capacity for using StreamReader or StreamWriter on server?
I have the following subroutine in an asp.net application class. The subroutine writes data to a text file upon application login. My question is that if this function was called at the same time by two different users would it cause any kind of error. Is there a need for a try catch?
Public Shared Sub writeToLogFile(ByVal UserName As String) Dim strLogMessage As String = String.Empty Dim strLogFile As String = System.Web.HttpContext.Current.Server.MapPath("~/Log.txt") Dim swLog As StreamWriter strLogMessage = DateTime.Now.ToShortDateString().ToString() " ==> " & UserName If Not File.Exists(strLogFile) Then swLog = New StreamWriter(strLogFile) Else swLog = File.AppendText(strLogFile) End If swLog.WriteLine(strLogMessage) swLog.WriteLine() swLog.Close() End Sub
We have encountered this difference in file creation while using a HttpHandler Versus a Code Behind Aspx page. We are reading a saved jpg/png picture as byte array from a 'Image' field in sql server database and create a physical file in the server. Both the Aspx Page and Httphandler use the same code pasted below.
//Begin int docID = Convert.ToInt32(Request.QueryString["DocID"]); var docRow = documentDB.GetDocument(docID); // Retrieve the physical directory path for the Uploads subdirectory string destDir = Server.MapPath("../../Uploads").ToString() + "\"; string strFileName = destDir + DateTime.Now.ToFileTime() + "_" + docRow.DocName.ToString(); FileStream fs = new FileStream(strFileName, FileMode.CreateNew, FileAccess.Write); fs.Write(docRow.DocData, 0, docRow.DocData.Length); fs.Flush(); fs.Close(); // End
After the file is created, it is viewable as a jpg/png Image only in Aspx Code Behind. While in case of HttpHandler it is not a valid Image.
i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup
I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A. I'm trying to stream an array of bytes to A, but it seems like the Response.BinaryWrite method completely overwrites any heirachial controls (I can't see any of B's other controls besides the image).
How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.
I need to have a function created for a website(asp.net 2.0) that will allow the user to add text to an image and preview the image with the text on it.
I am showing images of members on my website. The images are already saved to file. I want to add some text to the image that is loaded in the image control. I don't want to save it to file, just display the change on that web page. I have seen code on how to do this but I do not see how to load it into an image control. Is this possible without saving it to file?
how to convert both text and image together into an image. To clarify my question I can say if I have a text editor where I can add both text,image,audio or video player, how canI convert the whole texteditor.text (it gives me html code) to an image and save it in a file.
1) The image is from a asp:image tag 2) text is from asp:label
view here : [URL] How can I get text to start after the image is set in the top left corner, and then have text wrap underneath the image, if the text is long enough. I need to use asp:image and asp:labels as the inputs are populated from codebehind.

To clarify my question I can say if I have a text editor where I can add both text,image,audio or video player, how can I convert the whole texteditor.text (it gives me html code) to an image and save it in a file. I will be highly pleased with your answer.
I have converted text to Image(.png) using ASP.NET C# in Visual Studio 2010. But the image created cannot be displayed in the browser after submitting and it shows an message The image "http://localhost:49670/WebSite1/Default.aspx" cannot be displayed, because it contains errors.During debugging there is no error or warning or anything like that. How can I resolve this?
