View 4 RepliesIn my program, I need update a filed to the database. The field is for a pdf file content. I know, maybe I should save the pdf file to the local file system, and save the file path to the SQL. but, right now, it is the file content saved to the SQL.
from my program, it loads the file which is input by user. I use File.ReadAllBytes. Then, run the stored procedure on the SQL server, and use the bytes[] as parameter, to insert the file to the SQL. it works fine when file size is small. However, as file size becomes larger, say 200MB, sometimes, it pops out of memory exception.
So, I'm thinking, maybe I can load parts of the file, say 1MB a time, then update the database, then loop. so, this way, no matter how large the file is, it should not have any problem.
my question is: is there a standard way to do this? so, I should not save file content to the SQL at all? shoudl save file in file system, save the file path to sql only? or there are other way to deal with this?

View 2 RepliesJust wondering if anyone has any idea how you can determine how many bytes of a request have been read/received by the server... In other words how do I stream http request...
In that, users are uploading files and I want to report on a perotic basis how many bytes have been read/received so far.
I have a bytes of data. Eg : 1024 bytes. And in that, say "Name Age Occupation" etc. All are only values. I have another skeleton xml which will have the <Name/><Age/> etc.
I need to loop through the bytes, say first 5 bytes is Name, Next 2 bytes is Age etc and fill up in this XML. I'll have 1000s of records and so need to know which way is the fastest.
Will the code be fastest or is there any way i can do by XSLT or similar component?
How can I pass the content of a File to a array of bytes?
View 3 RepliesI need to find a way to accurately calculate the byte size of the text inside a particular textarea. I am working in .Net so I have access to those libraries, but I'd prefer a Javascript solution. How many bytes is each character worth? What would be the most efficient way to count and multiply? Or am I missing a better way entirely?
Edit: I'm attempting to determine the download size of a piece of Javascript that has been pasted into a textarea. The closest thing I could find to this is ][URL]. I don't want to just lift their code, especially since I don't fully understand it.

I have a database which signature images. Images are saved in binary.
I want to retrieve the image and display in an image control. I am kinda new to ASP and what seemed so simple has suddenly become a real problem.
The at the botom is how I would do it on a winform. Unfortunately I have no picturebox control in .asp. So how do I get the image stream into image1.imageurl?
Is there a way to put the stream into a session variable and then point to that as a url?
for instance replacing the last line below with this and then pointo to it from image1.imageurl?

Using the FileUpload Control, I know I can get the size of a file using: PostedFile.ContentLength. Using VB, is there a way to show Bytes being loaded in Real Time? In other words, if 1000 bytes has already been loading, a Label will show 1000, when 4263 bytes has been loaded a Label shows 4263, etc.
View 2 RepliesI need to serve MP3 content that is generated dynamically during the request. My clients (podcatchers I can't configure) are timing out before I'm able to generate the first byte of the response data.
Is there a way to send fodder/throwAway data while I'm generating the real data, to prevent/avoid the timeout, but in a way that allows me to instruct the client to ignore/discard the fodder data once I'm ready to start sending the "real" data?
I have a gridview with a Download button that serves a download to a user. I put it in App_Data so its secure so people can't try to download it. However, when I use this code, the save as dialog box pops up, and when i hit save as, the file immediately finishes loading - and it's just 0 bytes. The file is 5 Megabytes.

My query is that I have an sql field for image with db type "Image" , now I have successfully inserted some images in the form of bytes, now how to read those bytes of image from database and convert, show in gridview?
View 1 RepliesI have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.
