View 2 Repliesi'm new to c# and i wanted to know how can i allow user to upload a picture from a text box and a button??
after uploading the picture, how can i save the picture in the database??
**note**the picture i allow user to upload need to be in a fixed size.
I have this code to insert a picture from database into an ImageControl on my ASP.NET form:
strConnString = "server=" + Server + ";database=" + DataBase + ";UID=" + UID + ";password=" + PASS + ";";SqlConnection MyConnection = new SqlConnection(strConnString);SqlCommand MyCommand = new SqlCommand("SELECT Pic FROM MEN WHERE ID=5", MyConnection);MyConnection.Open();SqlDataReader MyReader = MyCommand.ExecuteReader();if (MyReader.Read()){ byte[] m_MyImage = (byte[])MyReader["Pic"]; Response.BinaryWrite(m_MyImage);}
And I have this ImageControl on the form:
<asp:Image Width="88" Height="100" Runat="server" ID="m_Image" NAME="m_Image" />
but when I run the code, I see the picture big on the screen and not in my ImageControl.
i also put this in the form_load:
m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook
but still dont work

I am using VS2008 & IIS7 with Windows 7 & IE8. I am debugging locally.
On a certain situation on my screen, VS cannot postback a page. I am getting the following error and have tried everything I can think of to resolve the issue, but to no avail.... I have used local IIS and also just the internal web server as well.
Unable to download pagename.aspx from localhost.
Unable to open this Internet site. The requested site is either unavailable or cannot be found.
I want that my web page should open up in full screen. Is there any code that i can put in my page load event so that the browser should set itself to full screen i.e. same as F11.

View 3 RepliesMy problem is somewhat specific and I do not have enough javascript knowledge to get this rolling.
I have a textbox. Based on what I enter in this textbox I am passing that to a webpage as a parameter and I need that to webpage to open up in a frame.
Here is the code that I currently have. This code is executed on textbox text changed event and is an autopost back. As you will notice this has issues in cases when I click on the submit button but do not leave the textbox... Not sure but it seems that browsing away from the textbox fires the textchanged event.
Is there a java script I could use instead of this postback?

I build a website with management system. In the management pages, I can upload pictures to a specific folder in my website. While doing it in my localhost in works perfect. While doing it on the hosted site, I get: A generic error occurred in GDI+. I read a little bit about it, and relized that it is probably an authorization problem. I asked the hosting to let a iusr_xxx permition to that folder. I've just informed now that it was done. The problem still occures. Here is the problematic code. It falls on the save command:
using
{
bitmap.Save(MapPath("../images/lawyers/" + fileName), image.RawFormat);
}
I tried already to put GC.collect(); after this line and alse I tries bitmap.Disppose() after this line.
I want to rename the image when uploaded to server. How to get it Give me code if possible.
