I have a simple vb.net app and I'm trying to update a one row Access table with data from some textboxes. This is a learning exercise for me as I am coming back from not programming for almost 10 years, and know there are lots of other ways to manage this data, but I'm just trying to understand different aspects of ADO.net a little better.
The ERROR I'm trapping is:
"Syntax error in UPDATE Statement"
Any thought's as to what is going on? (See CODE and stuff below)

I am making a booking system. I am using same form for insertion and updation. How can I update by taking the values from the textboxes. For example if the user enters value for just 2 out of 8 fields then How can i update just 2 fields without affecting the rest of the record. I mean to say that if I use a single update query using all the fields then if some textbox is left empty then it will replace the database field value by null or something else.

I was using 2 forms, the first one has general data capture and the second one is a calendar form. On Form1 I have mulitple windows controls. A Textb ox and beside a Calendar button. When I click on a Calendar Command button, it should open calendar form and once the user selects the date, the date should be placed in the text box on the form1. Identical to this on Form1 I need multiple textboxes that needs date to be captured.I cannot use a global variable for this as I need to validate mulitple text boxes. To explain this, I have a Transaction Date and Date Received. I need to validate whether Transaction date is prior Date Received or not? I dont want to use several global variables b'coz I might need multiple validations as above. Please help me on this.

View 4 RepliesIt can be just a hint if it's too much code for the whole thing. This is the assignment:

This form will collect from the user their name and e-mail address. It will display for them what they entered and then ask them to be sure they entered the right name and e-mail address. If the user selects �yes‟ from the message box, the name and e-mail address will be added to the data file.
I think I'm over thinking this, but I'm not sure where to start.

My problem is when the new data comes out from the API, if it is equal to the previous data and it will appear 0. But what i want is the new data comes out is 0 and it will equal to previous data. e.g: first data comes out is 12.00, in above case, if the second data comes out is 12.00 but it will shows 0 which means unchanged. But in my case now, i want if the first data come out is 12.00, then if the next data is unchanged (0) and it will appear 12.00 and so on.

how to display data in grid view using code that you can edit, update and delete the data...do i need to have a stored proc in this?
View 4 RepliesData binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
