Writing SQL In Code Behind To Gridview On A Different Page
Nov 4, 2013I am using Visual Web Developer Express with VB.net and have a website with 2 pages in them called "Tables.aspx" and "Variables.aspx". On the Tables page the user is required to enter a variable name in to a texbox, which I want then to take the user to the Variables page and have the gridview display the sql result. In behind the search button on the "Tables.aspx" page I have the following code.
Code:
' Search button code
Dim search As Char
Search = CChar(txtSearch.Text)
If Search = "" Then
MsgBox("You cannot leave this field blank.")
[code]....
On the "Variables.aspx" page I had decided to use data readers which brought up only one of the columns however I realised using data readers would mean I would have to individually position each textbox which I am not sure how to do.
Basically what I would like to know is how I do get the result of sql= "SELECT dbo.NILS_tables.Table_ID, dbo.NILS_variables.Variable_Name, dbo.NILS_ variables.Variable_Description FROM dbo.NILS_variables JOIN dbo.NILS_tables ON dbo.NILS_tables.Table_ID = dbo.NILS_variables.Table_ID WHERE dbo.NILS_tables.Table_Name LIKE '%' OR dbo.NILS_tables.Table_Description LIKE '%' " on to a gridview on the "Variables.aspx" page? NB the code for the search button is stored in the code behind file on the "Tables.aspx" page.

View 1 RepliesSecurity :: Test The Login Control Without Writing Any Code?
Aug 9, 2010I'm trying to test the login control without writing any code. According to Murachs book, you can drag and drop the login control onto a Login.aspx form. Use the ASP Configuration Security tool to create user, roles, and access rules for the website. And you should then be prompted for authentication. I created two folders in my website, admin and users. The admin folder has a admin.aspx form and the users folder has a users.aspx form. I also edited the access rules to only allow admin to access the admin.aspx and only allow user to access the users.aspx form.

Httphandler Version Aspx Code Behind Writing Image File?
Mar 31, 2010We have encountered this difference in file creation while using a HttpHandler Versus a Code Behind Aspx page. We are reading a saved jpg/png picture as byte array from a 'Image' field in sql server database and create a physical file in the server. Both the Aspx Page and Httphandler use the same code pasted below.
//Begin
int docID = Convert.ToInt32(Request.QueryString["DocID"]);
var docRow = documentDB.GetDocument(docID);
// Retrieve the physical directory path for the Uploads subdirectory
string destDir = Server.MapPath("../../Uploads").ToString() + "\";
string strFileName = destDir + DateTime.Now.ToFileTime() + "_" + docRow.DocName.ToString();
FileStream fs = new FileStream(strFileName, FileMode.CreateNew, FileAccess.Write);
fs.Write(docRow.DocData, 0, docRow.DocData.Length);
fs.Flush();
fs.Close();
// End
After the file is created, it is viewable as a jpg/png Image only in Aspx Code Behind. While in case of HttpHandler it is not a valid Image.

C# - When To Choose Javascript Injection From Code-behind Over External Js File
Jan 18, 2011I'm working on a C# web app and I've to handle some javascript code.
I can do it both using javascript injection from my .cs file, which I'm doing now or choose to include my code into an external js file.
I would like to know when you would prefer to choose one way over the other.
According to me, it can be more clear to put code in external .js file and it can ease debugging.
Code injection from code-behind would however keep together all the necessary code for my component.
