Please verify the installation of the component or download from the [URL]
1. Just create a new MVC project

3. Selected the "Data" option at left hand side and gave a name for the mdf file which is same as my current database mdf file name.
4. After that, clicked on Add button.
5. Then i got above error messages.
6. So do i need to install SQL Server Express 2005?
I tried in VS2008... Tools -> /Options -> Database Tools -> Data Connections, and changing "SQL Server Instance Name (blank for default)" to connect to my instance name but still it didn't work. I couldn't connect to the database from visual C#. I have read several threads about it but I couldn't get any good solution that can solve my issue.

I am facing a problem with retrieving an image and showing it on asp.net grid. I migrated MS Access database to sql server. Image are visible in Crystal report when fetched from the same database (migrated sql server database). But same images are not visible in ASP.Net grid view or simple asp.net image control. Following is my code
SqlConnection oConn =
new
SqlConnection(ConfigurationManager.ConnectionStrings["csr"].ToString());
oConn.Open();
SqlCommand oraCmd = oConn.CreateCommand();
oraCmd.CommandText = "select top 1 photo from [test] where photo is not null";
SqlDataReader dr =
null;
dr = oraCmd .ExecuteReader ();
if(dr.Read ())
if (dr["photo"] !=
null)
{
Response.ContentType = "image/gif";
Response.BinaryWrite((byte[])dr["photo"]);
}
This function is getting called from another page . "hlopen" is hyper link in the grid. hlopen.NavigateUrl = "GetPhoto.aspx?id=1";
How can i do that with ASP?
Is this process going to be a great overload for the server?
Could i use an image for a watermark instead of simple text?

View 5 RepliesI am sending e-mail with asp.net and I can add one image to this html body of this e-mail by using alternativeview. but here is the deal;

I have an aspx page which I am pasting the code from. This page is a preview gallery which when I create a new gallery in my admin panel it auto updates to this page and places the text name I assign in the admin and assigns a page link which takes users to the actual gallery page for that preview... for instance I log in as admin and select manage free gallery.. enter the gallery name (for example" free preview") upload 8 or 9 images and a slideshow then hit submit. The gallery is then created and a link to that gallery is placed on my page for all free galleries. I want to not only have a link but an actual thumbnail image for these.. how would I do this given the code I am pasting below? I would also be willing to just eliminate the text link and go with a clickable thumbnail with a short description under it which actually would probably look better anyway. Pasted ASPX Code follows:
ok so I cant post the code because I am new..
I'm not sure if I titled the question correctly so it would be better if I explained what I'm trying to do. I am using the ASP .Net Chart Control to create a line chart showing numbers of trouble calls based on date. What I would like to do is implement a way of annotating the chart with data whereas if there was a spike in trouble calls a line, or asterisk, etc would direct the viewer to "read notes below for an explanation for why the numbers spiked here".
From the samples for the chart control there is a way you can add a bitmap to the chart, however I don't see how that will be effective here because the explanations will come dynamically from a database.
I am currently attempting to build an Organisation chart image map based on the data in our SQL Database. I am doing this at runtime in an ASP.NET C# web application.
I have been asked to investigate the possibility of adding personal images from our SQL DB into the chart and I am completely lost... As I am creating an image already, how would I add an existing image (which is stored in the database) into the new one?
The code I am using to generate the image is as follows -

View 3 Repliesi have started to do a Asp.net Website Project...Am given few Images , to place it according to the requirement Web Page Sample image given by the client....Am just wondering how to calculatethe exact dimensions of the various parts of a page for Placing Images Perfectly.
Am using Html Divs , Css and a tool called WebPage Maker..Using WebPageMaker Tool i can place images and by running on a browser ,i can calculate the dimensions of that particular part[ For Ex:Header Image] by using FireBug Tool.....
But when using those dimensions[Left,top,Width& Height], at asp.net page by using Divs & CSS...Total page gets collapsed and images just run away.........
Whats the best Approach to do this..??
As of now,am given Few images[Cut], and the original required Image..On seeing that , i should place images accordingly...
But Am not able to calculate dimensions for using at Html Divs and CSS in a ASp.net Page..
I have following code that I can only add one image per row although I can add Listbox items as I wanted.
If "imgtag" 1~5 is checked, I get these in the listbox.
ie. ImageID = "cat"
listbox1. item gets - cat1, cat2, cat3, cat4, cat5
however I can only create the last image instead of 5 images.
- imageID - cat5
I assign each image unique ID.

I need to add Images in my Rich Text Box editor after a paragraph. I have gone through this article and it is very useful.
{URL] ....
But I have some question:
1. Can I add multiple images in this Rich Text Box.
2. After adding images and content in Rich Text Box, I want to save it in database. So where will I save images and content. I mean images in folder and content in database or both in database.
Is there a way to process images once uploaded to my asp.net site, to put a watermark or some text across the image to copyright the images? I would like to do this server-side if possible.The other option I have discovered here [URL] would be to store the images as they are on the server, but to manipulate the display so it appears the image is watermarked . However, this solution is in PHP. Does anyone know a good PHP to VB.NET translator?! Or does anyone have a good suggested link, idea or code? Or can I add PHP to my ASP.NET site?
