I'm just stuck as I can't work out the best way to do it,
I'm trying to put a registration page together in Visual Web Designer.
I would like to send a confirmation Email after someone is leaving his registration data and pressing the INSERT button.
The key fields in my database are: Email, Name, Surname, Address
Before I send the confirmation Email I would like to check if the email value entered in the form is realy added to the database.
I was copy past already some C code in my page, therefore it will be fine if the code can be in C.
- checking if record is realy added to database after pressing INSERT button
- setup the confirmation Email
I have a delete button bellow my gridview and I want a pop up to show when no record is selected and tell the user to first select a record. The button click event would show the pop up, but my gridview data blanks out.

View 5 RepliesMy students are working on an ASP.net VB application for a Web Programming competition and we are having problems with a page where we want an URL string to return all values from our database. Here is the page: [URL] If you use the jobs by category menu on the left side, if you select a job category (ie retail) it will pull up all the jobs from that category. By using a query in the URL like this: [URL] What we need is an option that would pull up all of the records regardless of category. So we made a menu option that passes the value "all". Like this: [URL] We use this information for the dataset we created (we're using Dreamweaver, ASP.net VB and and Access Dbase). We made a dataset SQL as follows:
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin and jobcategory = ?
ORDER BY jobs.dateposted DESC
This works fine if a value is passed. For example if "retail" is picked from the menu it passes the value just fine and returns all jobs that have "retail" as the job category in the database. My problem is, how do I modify the above Select statement to show all jobs in the database if the value "all" is passed for the jobcategory. My first thought was to create an If statement that says something to the effect of:
If jobcategory = all THEN
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin
ORDER BY jobs.dateposted DESC
ELSE
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin and jobcategory = ?
ORDER BY jobs.dateposted DESC
END IF
But I haven't been able to figure out the correct syntax. I also tried making this work by using a query in MS Access:
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin
AND (jobcategory = @jobcategory or @jobcategory = 'all')
ORDER BY jobs.dateposted DESC;
(which does work within MS Access) and calling the query in the Dreamweaver dataset but apparently MS Access can't do that.This seems like it should be easy but so far this problem is kicking my butt.
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
I have my code output a gridview with all the data with an option to select records. I'm trying to make a code which would allow me to select a record, and then print this record using a specific Report stored in MS Access.
I've located the code to print the Report it self, but it prints ether all the records or a range.
I have the following query which gets the top record SELECT TOP 1 username from users GROUP BY username ORDER BY COUNT(*) DESC. now i have a second field which gets the numbers of views of each user i need to return just ONE single field and that is the same username field but based on views field i can do this:
SELECT TOP 1 username,views from users GROUP BY username,views ORDER BY COUNT(*) DESC but i just need that username field based on views not both!
1.Category:
CatID(Pkey),
CatName,
ParentCatId(Fkey)=> CatID is used as a ParentCatId
2.Comp_Cat:
CCID(Pkey),
CatID,(fkey),
CompID
In my stored Procedure I am passing PageNo,CompID.. My requirement is that One parent CatName is displayed Per page but only one time.
I have a gridview which is bound to a sqldtatasource. The gridview has 3 columns and a select button. The data in the gridview pulls up just fine when I run the application and the first record is selected.
However when I select one of the other records, the gridview will not select it. The postback occurs and it remains on the first record. Here is code for my gridview and the sqldatasource:

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.
View 6 RepliesLast night I started working on an NHibernate provider. I'm creating a criteria that several records will match, however I only want to return the most recent record (the record with the largest Id). I thought UniqueResult() would do this it cannot be used if a list would be returned otherwise.
I could theoretically select the full list and then return the desired record, but I believe there is a better way.
I'd like to use sql to select top (#) random row into another table, but it inserts the same record a few times sometimes. I want to avoid duplicates to be inserted, what shall I do?
what I've got for now is
INSERT INTO CompWin (PrizeID, EntryID, UserID) SELECT TOP (50) PrizeID, EntryID, UserID FROM CompEntry ORDER BY NEWID()
If I have records in a table in this order:
Id - Date - Type
1 - 2011-03-01 - 1
2 - 2011-03-02 - 0
3 - 2011-03-03 - 0
4 - 2011-03-04 - (-1)
5 - 2011-03-04 - 0

View 4 RepliesOn one (aspx) page I have a GridView (GridView has multiple pages). After a user selects a row/record and clicks "edit" he's redirected to another (.aspx) page where he edits the selected record via DetailsView. fter clicking update on DetailsView he's redirected back to the page containing the GridView.What is the simplest/shortest way that the updated record is automatically selected on the Gridview (e.g. at Page_Load event)?
