I am attempting to insert a new record into a table in a dataset using LINQ commands. The data in the record is defined by the text in some text boxes.
At the moment, I am working with the following:
[Code]...
User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
could someone tell me what i am doing wrong in this codeProtected Sub insert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Insert.Click

I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.
First an instance of the Customer Class is created and this seems to be successful. But when I take that customer object and run the AddCustomer method of the customer class it is not successful in that the database does not reflect that the record was ever added. [Code]
Here is hte code I'm using to insert into my database:[code]I believe it is Cell 4 that is causing the exception, because it is a checkbox column and i'm not sure what syntax to use to store the "CheckedState" of it.Yes, I know I should be using parameters, but I don't know how yet, and I would like to make the INSERT statement work before implementing the paramater approach with it.
View 5 RepliesIf I need to set the value of a checkbox (threestate) inside of an INSERT command, what would the syntax be? I've tried 'True' but that fails and I can't think of another way to do it.

it is Effective But I need to add a condition which is: Add only the rows where the column 4 is checked.
Note: the type of Column 4 is DataGridViewCheckBoxColumn
I am working on a Vb.Net application . I have a compose message web form where users will compose a message , but after the users click the send button I am inserting in the message table. All is working fine , infact great . Now I am thinking of adding a undo button where I will show this button if the user will click the send button . If the user clicks the send button and leaves the undo button the insert query will be fired. But if the user clicks the send button , but then he clicks the undo button the the insert query should not be fired or it should be rolled back ...or something ...I mean the user should be back on his compose message state as before.

If the button NCOSubmit (see below) is clicked I want to send all data to the SQL database through the sqlText string. Currently I put a break point under the code presented below, so the error cannot come from there.

I am having trouble with the insert command, my code is:

aatblWills1 is my sql server table with 3 fields: WillID(PrimaryKey, integer auto increment); UserName(nvarchar(150)) and TestatorName(nvarchar(150)) (there are some other fields in the table but I've set them to allow nulls)I am not getting an error message, it is just not inserting any records into the database.

i created a procedure stored in the oracle database create_user and accepts a few parameters...
procedure create_user
( p_user_num out tbl_users.user_num%type
,p_username in tbl_users.username%type
[Code].....
so i run the form, click the AddNew button in the BindingNavigator, enter the data in the textboxes and then click Save. i receive no error but the values of the textboxes are not being passed to my stored procedure. it is creating records but all columns are null.
i checked this by using an SQL Editor to query the table back-end.

View 2 RepliesI'm trying to add information to a SQL database. I've had trouble getting it to update (and I'm only doing one entry at a time!). However, even one at a time gives me trouble. The red line of code gives me this error: Update requires a valid InsertCommand when passed DataRow collection with new rows. what I'm doing wrong--I think it may be syntax, but I'm think the parameters are correct.
