But what I would like to do is take a value from a textbox and add that to the chosen field database.

This error has me completely baffled. There is no indication (that I ca FinD as to what field won't handle the information. Heres the situation:I am using an Accees query to insert a new record in a table with 49 fields. Of these fields, 1 is an integer, 7 are booleans and the other 41 are text fields. The text fields represent either Time of Day or a Timespan.
My field sizes are:
For time of day 8 digits(example 08:00 AM)
For a time span 5 digits(example 03:30) I will never exceed 2 digits for
hours
I have checked every field in the dtatbase and they are all as noted. I am at a loss as to how to proceed.
I have an open database (dataset) with two tables. It is binded to toolboxes, but I have one field, what I have to calculate about other parameters. I have binding navigator, and I can set field values from controls (eg. toolbox). I can step my rows, with binding navigator. I can update my database. But how can I set field value from code?
I want a code line:
database.fields("fieldname") = something - or something like this
I have a RDLC report with a list that contains a table. I require a calculated column whose value depends on values from previous rows. Outside of a report I accomplish the same thing using code in a DataGridView's DataBindingComplete method.
From within a report how do I refer to specific cell values from previous rows? embedded code, but I have not had luck (#Error).

I know this sounds simple to the majority of the database gurus out there but I am finding it difficult to find anything related.I am using Visual Studio 2008 VB.net winforms application.I have a form which contains a datagridview. what I want to do by push of a button is set the field "OnHand" either to default or 0. The 'either or' is really for you guys. Which ever one works the best in terms of reducing code or functionality is obviouls prefered.Once the 'OnHand' Fields in every record has changed then I would like to save all the data back to the database'This is more than likely very simple I just cannot find anything that discusses this kind of thing.

I've been staring at this and can't seem to come up with a solution. I've tried several different methods that i found on the web but to no avail. I'm hoping you all could take a look at the code below and give me some direction as to why I'm receiving the error "The INSERT INTO statement contains the following unknown field name: 'Deposit_Date' . Make sure you have typed the name correctly and try the operation again. Sorry if it's kinda jumbled below
Code:

"Miscellaneous_Adjustment, Dispense, Dispense_Adjustment, " & _

I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.
I have a table and I want to select a field in it and then display it in a text box
something like:
SELECT userName
FROM userTable
WHERE (userLogged = 'ON')
how can I display the selected username in a textbox?
BTW the userLogged indicates wether the user is logged in or not
if the user is logged in then the userLogged will be changed to "ON"
if the user is not logged in it will be "OFF"
I know it's not that practical but I'm still practicing.

Im trying to push (for what of a better word) the output of a button which is in a text box to a field within mysql. I have followed the tutorial on here for connecting to a mysql database.

But I cant find anything on how to achieve the reverse of this - populating a field with data/text from a textbox.
View 14 RepliesI'm using VB2005 and I got a message error in a runtime: Abstract does not belong to table tblBooks. I don't think that the problem is its datatype. I'm currently using MEMO datatype because I need to load it more than the capacity of string.
