Resizing Images With .NET And Saving To Database?
Mar 18, 2010I need to take an uploaded image, resize it, and save it to the database. Simple enough, except I don't have access to save any temp files to the server. I'm taking the image, resizing it as a Bitmap, and need to save it to a database field as the original image type (JPG for example). How can I get the FileBytes() like this, so I can save it to the database?Before I was using ImageUpload.FileBytes() but now that I'm resizing I'm dealing with Images and Bitmaps instead of FileUploads and can't seem find anything that will give me the bytes.

Web Forms :: Saving File To Database
Mar 26, 2012I have two buttons ... one is insert btn another one is fileupload btn.
In the fileupload btn i creat a code in blow. I can upload the file successfully.
I need to insert a file in sql by using insert btn. For that I can create a insert query every thing but I cannot access the string filename value in the insert btn. So how I get the string value for insert btn. I mentioned the insert query also.

string filePath = FileUploadControl.PostedFile.FileName;
string filename = Path.GetFileName(filePath);
string ext = Path.GetExtension(filename);
string contenttype = String.Empty;

Insert Btn:

cmd.Parameters.AddWithValue("@FileName", filename);
cmd.Parameters.AddWithValue("@ContanType", contenttype); cmd.Parameters.AddWithValue("@Data",bytes);
con.Open(); cmd.ExecuteNonQuery();
con.Close(); Response.Redirect("Default.aspx");

Web Forms :: Saving Image To SQL Database As 0X00000?
Jan 4, 2011I have a fileupload control in my form which stores image to the SQL database as binary data.
BUT it stores as 0X000000.... I just realized that.
BUT IT DOESN'T MAKE ANY SENSE BECAUSE WHEN I PRINT THIS BYTE ARRAY IT SHOWS THE CONTENT.
This part is the server side code:
[Code]....
StoreToDatabase function:

DisplayFileContent function:
[Code]....
Displaying function shows like 2552162552240167470737001110960960025521906708667658777998101220131211111225181............BUT IN DATABASE it stores like 0X00000000000000000...
Saving SelectedValue Of CascadingDropDown In DetailsView Into Database?
Dec 14, 2010I have a form for our staff to list an event in a calendar system. In the form, there is a DDL for their Department, and a CasscadingDropDown that provides a list of staff members (the staff list is filtered by Department, as chosen in the first DDL). When the form gets submitted, I need to store the selected values of both DDL's (DepartmentID and StaffID, respectively) into the database.
So, I have a DetailsView, and am using the InsertItemTemplate. Now, I can get both DDL's populated correctly (with the cascade working correctly), and I used custom DDL's derived from the standard DDL class to avoid any Postback/EventValidation problems. But I can't seem to get the values of the user's selected items so I can save them back into the database! I've tried many different approaches, but all I seem to get returned is a value of "".
Here's what I have so far...

Saving And Restoring Rich Text To/from Database?
Feb 17, 2011I am creating a winform app in C# to store formatted text from a rich text box to MySQL database, which can be retrieved back to the rich text box. The database field is a VARCHAR and my code is something similar to below. But I'm getting "file not in correct format" error. Can anyone tell what could be the problem? Is the VARCHAR field okay to store it or should I change it to a BLOB?
string rtfText = this.richTextBox1.Rtf;
// save rtfText to database field as varchar
// ...
// reload rtfText from database as string
this.richTextBox1.Rtf = rtfText;
