View 1 RepliesI have a app that records some jobs and those jobs can have notes attached therefore i connected the table with a foreign key, my notes to a Job.
in the details view of the job i allow the user to view the jobs by sending the id and fulling all the notes that match the id in the index view for the notes table. in the list of notes i have a action link to create a new note, here i sent also the id of the job to the create action of the control and try to insert that intot he note JobId to make the reference. I get this error and the note is not created. the note creats from code but not via the note controller creat action.
i get this - An error occurred while updating the entries. See the inner exception for details. below is the create action in the note controller
public ActionResult Create(int id)
{
// var newnote = db.Jobs.Include("StatusNotes").Single(j => j.JobId == id);[code]...
how i call a image field from another table? the image field in the same table is working fine but the one on the other table is not. I have created the foreign key and made the connection... What else do i need to do to call that field? Page Load:

int COMPANYID = 0;

I am using a viewstate to store the company Ids and splitting at hyphen.
protected void onCompanychange(object sender, EventArgs e) {
ViewState["companyID"] += companydropdown.SelectedValue + "-";
String companyids = ViewState["companyID"].ToString();
string pattern = "-";
company_array = Regex.Split(companyids, pattern);
company_length = company_array.Length;
}
Company array is a string array where i have stored the company ids
the problem is company_array[0] has the initial value of the dropdownlist(company) --select company which is why m getting the error(cannot convert data type nvarchar to int) . I have used the same logic in many places in my project it did not give any error.
int count = 0;
company_length = company_length - 1;
while (count < GridView3.Rows.Count && compid_counter < company_length ) {
cmd = new SqlCommand("insertWorkDetais", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@trainerId",trainerID);

I have set up Membership and Roles and can create users and login using the ASp Login control. However I need to associate users with customers (in a Customers table in the database) and display content according to the customer that the user belongs to. Is the best way of doing this to create a foreign key field in the aspnet_Users table relating back to Customers table which would have to be updated manually after creating the user or is there a better way?

We are using Sitecore.NET 5.3.1 (rev. 071114) and we found out a problem. When we are trying to change information in a Rich Text Editor field on the Master database and save the information, this information is not stored and instead the old information appears back into the RTE field. I have been trying this on the Web database on which this is not happening. However, changing this information on the web database feels useless because a publish will just change every information that does not correspond to the data in the Master database in which i just can't edit this field. So I'm having big trouble at this point since this is for one of our bigger customers and they really want this fixxed asap.
View 1 RepliesI have set up a ASP.net MVC application which uses the default forms authentication. It uses the ASPNETDB.mdf like shown here:
I then set up another database connection which is similar to the NerdDinner.mdf file above.
I have a post that belongs to a user. It has a UserId value which needs to be a foreign key to the information in ASPNETDB.mdf. When I go to add a foreign key, I can only see information with regards to the table I made. How do I go about doing this?
i am using sql server 2005 as backend for developing webforms with asp.net using C#.i have two tables table1 and table2.
table1 has user_id(primary key,not null),user_name. and table2 has dept_id(primary key,not null),user_id(foreign key,not null),dept_location.
Firstly i created table1 and insert data in it.. later i created table2 with foreign key relationship with table1..In the add form design of table2 for entering data and insert into table2,i placed a dropdownlist which is binded with user_id from table1...dropdownlist's.datatextfield is equal to "user_name" and datavaluefield is equal to "user_id"..i have to select user_name from dropdownlist.... what i have to do is to insert data into table2... i used the simple sql insert statement as follows..
insert into table2 values(......); but it shows error :insert statement conflicted with the foreign key.

I am creating a winform app in C# to store formatted text from a rich text box to MySQL database, which can be retrieved back to the rich text box. The database field is a VARCHAR and my code is something similar to below. But I'm getting "file not in correct format" error. Can anyone tell what could be the problem? Is the VARCHAR field okay to store it or should I change it to a BLOB?
string rtfText = this.richTextBox1.Rtf;
// save rtfText to database field as varchar
// ...
// reload rtfText from database as string
this.richTextBox1.Rtf = rtfText;
I have a SQL Server table with a number of fields that are defined with the "Float" data type. I'm running a simple query to retrieve the data from this table and use it to populate a Data Table in my C#.net application.
I just discovered that the data type of the Data Table fields is Double, not Float as I expected. As such, when I store a value like 0.157 it ends up getting stored like this: 0.15700000524520874
I'm aware that such extra "noise" occurs when such a conversion occurs. My major question has to do with why .Net didn't set the Data Type to Float (ie. Single) when the table was first populated?

View 3 RepliesI have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
I want to create a site where users can create a very basic profile, with fields like full name, City, Age and Gender, and I want the data for every new member that signs up to go into a simple Table in my sql data base. reason being I want members to be able to view other members info in a table. I am familiar with the "CreateUserWizard", but that only allows me to work with certain predefined info (email, user id, etc). If I just anually add new columns to the table in which user ID and such is saved to, and customize the CreateUserWizard controller to have text boxes for the additional data that I want (i.e. city), will the CreateUserWizard know to save that additional data in the table?
Also, I know I can add fields to the <profile> tag in the web.config files, but I dont know where that gets stored. I want all the info for the user to be stored in one table in a sql data base so that I can easily access it with a quary. I dont see where the profile properties get stored, and how it can be linked to a User ID. by the way I noticed in other posts, there was a mention of a membership provider. I noticed that although I've added some "Login" controlls (i.e. login and CreateUserWizard), no membership provider has been added to my web.config file. Do I need to do this manually? or is there a menu item that adds it for me?
I've been using this programming style, that I've seen in an example and just started using it, because it does the job... I would like to know other programmers' opinion about it...
So the situation is when you have a GridView, or a control based on it like the RadGrid, and you want to keep track of a data table while you are adding, editing, reordering and deleting rows.
Using the session to hold the data table (or list of data) may not be the best solution, because the user may open two identical web pages... Using the ViewState to hold the data may be and option... I have been using an approach like the following:
[code]....
So using a static List variable, of a custom object (class), declared in the code-behind of the Aspx page, and updating it whenever the data is edited.

I have a project which generates snapshots of a database, converts it to XML and then stores the XML inside a separate database. Unfortunately, these snapshots are becoming huge files, and are now about 10 megabytes each. Fortunately, I only have to store them for about a month before they can be discarded again but still, a month of snapshots turn out to become real bad for it's performance...I think there is a way to improve performance a lot. No, not by storing the XML in a separate folder somewhere, because I don't have write access to any location on that server. The XML must stay within the database. But somehow, the field [Content] might be optimized somehow so things will speed up...I won't need any full-text search options on this field. I will never do any searching based on this field. So perhaps by disabling this field for search instructions or whatever?The table has no references to other tables, but the structure is fixed. I cannot rename things, or change the field types. So I wonder if optimizations is still possible.Well, is it?The structure, as generated by SQL Server:
CREATE TABLE [dbo].[Snapshots](
[Identity] [int] IDENTITY(1,1) NOT NULL,
[Header] [varchar](64) NOT NULL,[code]....
Performance isn't just slow when selecting data from this table but also when selecting or inserting data in one of the other tables in this database! When I delete all records from this table, the whole system is fast. When I start adding snapshots, performance starts to decrease. After about 30 snapshots, performance becomes bad and the risk of connection timeouts increase.Maybe the problem isn't in the database itself, although it's still slow when used through the management tool. (Fast when Snapshots is empty.) I mainly use ASP.NET 3.5 and the Entity Framework to connect to this database and then read the multiple tables. Maybe some performance can be gained here, although that wouldn't explain why the database is also slow from the management tools and when used through other applications with a direct connection...
I need to write a query to populate a gridview with minimum rates in ascending order for a month from three tables.For example i have three tables A,B,C as follows

i am trying to save an image to database as a byte[]
The array size before i save it = 2118.
but in SQL 2008 the maximum size for an image type is 16.
so i am trying to get the image using Response.BinaryWrite(byte[]) I get an empty image.
I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
