I have some fix fields in my database but user can add some another fields to my database if s/he needs. How can I insert data to this kind of fields if there are? For fixed fields I have used the follow cods

"INSERT INTO Wind_Parameters (ID, Name, CrX, CrY) VALUES ('" &
ID &

But I can't add optional fields to this code. I think I should use UPDATE syntax for fill optional fields after running this cod but I couldn't find correct syntax for it in visual basic 2010
I have an Access database file, which the application needs to connect only when it needs to run a query. The database has five fields. The first two fields contain numerical values (double). The rest are text values.
Well, I don't have trouble accessing the database file. In fact, I don't have trouble running a query on those three fields containing text values, either. But I have trouble making a query on numerical fields. If I run the following, the application will exhibit a data mismatch error.
'MyConnection As OleDbConnection
'MyAdapter1 As OleDb.OleDbDataAdapter
'nIP is a large number like 3647665152

I am trying to pull sql data into a text file. The code works just fine, until some new data comes in from lazy employees and a couple fields (used for notes/comments) are now left blank. Originally I've never seen them blank so I didn't think anything of it.
col2 = myreader.GetString(1)
It will error if the field is ever null - I even tried using a case when:
case when note is null then '" & empty & "' else note end and set the variable emtpy = '', but vb still thinks that it's null and errors?
experience on how to create an engine using C# (VB.NET is okay too) that is generic enough to handle most cases of MS Word text fields I need to fill with data I'm getting from a database? In short, I'm about to embark on this little Office automation excursion and I'm hoping a little bit of feedback here.

I have a text file data to insert into a database for report
ITEM01,Toy
ITEM02,Card
Let me briefly list down the steps i took to achieve my result.
1) Insert data into Database using text file
2) Display the records from the NEW Database(Item2) using DataGridView
3) Using datagridview, i use to checkboxes to determine the selectedRow
4) Once the selectedRow are selected. I press on Delete Button
Delete Button - Update the Item2 Table field 'Deleted' to 1 - Delete the ItemID by using datagridview selectedrow cell value Which means in 1 loop, i process two database transaction.. Is there something wrong? How do i shorten the process to just delete the item without querying two database.

I'm trying to insert a couple of fields into a csv config file and then update all other rows in the file at the same index by copying the previous 2 entries. I'm reading through each row and converting the row into a list(of String) because it seems to be the most flexible way. Ine initial insert works fine, but the code below doesn't. The actual insert code is:
[Code]...
pcIndex is the list index value from elsewhere in the code at the insertion of the 1st of a pair of values into one row. I need to update that index point and pcIndex +1 in all other rows. However it's not doing anything. Tried using lstSteps.Insert, InsertRange, etc. Am I using this right? Is there a better way? It seems to be over-writing the entry rather than inserting a new column and moving the others up, so it appears the list capacity value isn't updating - so I'm left with the initial row with 4 more entries than the others sticking out of the file.
What I want, is Some text fields to input text, and one image path, then I want to print that, in a format like..

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

View 10 RepliesI have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

I tried searching for a solution, but couldn't find anything, so if I am re-asking a common question, don't beat me too badly. For a class, I have to create a form that allows someone to enter in the names of six students, as well as five test scores each. It also averages the scores, and displays them in a label.
What I am wondering is if there is a way to clear the text from all 36 text fields, as well as the 6 labels without having to do everything individually?
I could certainly go through, and write out txtField1.text = String.Empty 36 times, but it seems there would be a more elegant solution. Also, if there is a way to do so, would the same would apply for putting the data entered into an array, or saving it to a file?
I am writing a little program that does the following:Allows the user to enter a id number.Then when the find button is clicked, we connect to the database and run a select statement for the id.I am trying to figure out how to get the first name, last name and birthdate into textboxes on my form.
I would like to have a way to display a messagebox if the resultset = 0 so as to tell the user no records found.Then if the information is correct I am going to have a button to update the information which is going to call a stored procedure I have in place to update the record.how to make the connection which I think I have working and then loading the individual fields into the appropriate textboxes.
I'm working on a project using SQL Server Express 2008 R2 and Visual Basic 2008.My table has 8 text fields, each using the data type VarChar(num) with the number(num) ranging from 5 to 50. There are also number fields and a boolean field in the table.When I try to insert or update the table in Visual Basic the program runs through to completion, but the VarChar fields only contain the first character. The other fields come out fine. If I create the record in SSMS the fields are not truncated.

View 1 RepliesI have a series of text boxes in my form that can accept 6 digits. Upon entering the 6th digit I want the focus to move to the next text box. Is there a way to initiate a Tab command (just putting chr(9) didn't work...so that may be wrong) once the counter hits 6? I currently have the following code, using the .focus command but I am hoping to not have to create 25 subs to set focus to the next. My current

I can't just add txtEnter2.KeyDown (etc.) to the Handles of the sub declaration because then they would all set the focus to txtEnter2 instead of to the next text box. I'm sure it is something ridiculously easy but it is escaping my grasp.
i have a form issue and return form. where Issuer_ID is the primary key, this form uses for boht emp and for student issuing book. at run time the user has to select a radio button for student or for employe. if he select student so after entering the full information when he press submit button so student query is execute and data stored in database, keeping the Employee field null, and when user select the employee radio button and after pressing the submit button, so employee querry executes and stores data in employee field, keep the student filed null. remmber and Student ID and Employee ID or foreign keys in isuee and return table and radiobuttons are not the part of database, its just on form.
now i want that when a user gives his issuer ID and at the lost focus event of issuer id, it is checked that if the record exists so the data is bind on the form, if does not exist so the user has to make entry, but if the data loads on form so how user will find out that this data is of student or of employee?
