Save byte array to Image with transparent background to client machine


I have an asp.net website and am exporting an image from the Report Viewer.  I have created my byte array to get the data from the report viewer and now I need to save an image with transparency to the client machine using the response headers.  I was able to do this by saving the array to the server as a bmp and then adding transparency and saving to the client as a GIF; however, the requirement has changed and now I need to do this without saving the file to the server and even though I have found several solutions using unsafe code these will not work for us because we are not allowed to use unsafe code in our environment. 


So in short I need a way to go from an array of bytes to a transparent gif and save to the client machine without using unsafe code and without saving a file to the server. 

Save images to SQL CE

Storing binary objects (such as image, office document etc.) into database is a little cumbersome when it comes to retrieval. Hence the most commonly accepted way is only store the file path in the database, and to store the documents on a file share.

Where to Filter the companies returned by the EF?



I am just starting with dynamic data. I have an enttity framework called UsersModel.edmx.

It returns a list of all companies in the tblCompany table. This list is really big.

I need to filter the list returned to all user controls on the client so that it only returns the company that have a CompanyTypeId= 2 or CompanyTypeId= 3 and company name != "".

1 - Is it possible to filter the company list returned on the server so that I can filter only once for all the controls that use that on the client?

My ideas was to do something like this using linq and lambda but I am not sure how:

return tblCompanys.Where(c => c.CompanyTypeId == 2 || c.CompanyTypeId == 3 && ).Where(c=>c.CompanyName != "").OrderBy(c => c.CompanyName).Distinct().OrderBy(c=>c.CompanyName);

2 - I have created a partial class and a metadata class and added the DisplayColumn attribute to use the company name and sort by company name ascending.

Could I use the code to filter the returned companies in this? where?

namespace MarsMedicalModel
    [DisplayColumn("CompanyName", "CompanyName")]
    public partial class t

How to cast integer values as an array of enum values?


Hello all!

I'm working with VS2010 Beta2, ASP.NET and Dynamic Data. I'm using VB but will certainly be happy to receive a C# example if necessary. Laughing

I used a few of Steve's examples (Writing Attributes and Extension Methods for Dynamic Data and Dynamic Data - Hiding Columns in selected PageTemplates) to create a custom property attribute to be applied to a dynamic data column and want it to accept an array of enum values (each value will represent a dynamic data page template where this column should not be displayed).  My new attribute works fine when I hardcode it like this, meaning the HideColumnIn attribute is properly populated with the array of enum values:

<HideColumnIn(PageTemplate.List, PageTemplate.Edit)> _
Public Property My_DD_Column As Object


However, I want to store the values to be used for the HideColumnIn in the DB as integer values that correspond to the

Profile not being save after redirect.



I am trying to save values into a Profile on Page1, then redirect to Page2 and access those values.  However, after the page redirects the profile values are blank as if they were never saved.   When stepping through the code I can see that they are being save on Page 1.

I suppose I could use session variables to store the information but I don't understand why saving the profile doesn't work.

private void PayWithPayPal()
        ProfileCommon profile = this.Profile;

        if (Global.CurrentUserName.Length > 0)
            profile = this.Profile.GetProfile(Global.CurrentUserName);
        profile.FirstName = uxFirstNameShipping.Text;
        profile.LastName = uxLastNameBilling.Text;
        profile.ShippingAddress.AddressLineOne = uxAddressLineOneShipping.Text;
        profile.ShippingAddress.AddressLineTwo = uxAddressLineTwoShipping.Text;
        profile.ShippingAddress.City = uxCityShipping.Text;
        profile.ShippingAddress.State = uxStateShipping.Text;
        profile.ShippingAddress.ZipCode = uxPostalCodeShipping.Text;

        Response.Redirect("~/expresspayment.aspx", false);

server side does not save data when using POST data to another URL using WebRequest


 I am using a IIS 7.5 on Windows 7. I have a simple application that uses System.Net.WebRequest to POST data to another URL (in fact, the server side URL is on my local computer and it is hosted in IIS 7.5).

  1.  The problem is the server does not save data from client although on the client side codes when I debug and I see the OK message return from the code line

   response.StatusDescription; // this has value of "OK"
2. How can I debug the server code side where to receive the request from client side who posts the data ?

The following is the codes for client who posts data using System.Net.WebRequest, and codes for server side who received posted data to save to database.

Client side codes: // also run on my local computer

Hello good people, 

I have this beast as an error. Did my research and found some posts here as well but did not do any good for me.
