VS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?

Jul 24, 2011

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .

The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

VS 2010 Finding Specific Text From Textfiles

May 27, 2012

I have an assignment due tomorrow, and I thought I had it all figured out but there is one question I don't know how to program. The assignment consists of a form with textboxes in which the user types info about a book (author, title, genre, etc.), which he can save to a textfile by clicking the save button. (At the moment it's not saving it to a textfile but just a 'file', which can be opened with notepad but is of no specific datatype, not sure how I do that, but is less important). There is also a button with which the user can display information from a different, earlier created textfile.[code]

VS 2010 - Search Dataset For Specific Record

Aug 1, 2011

My application will start (dataset filtered by username/date) and if it's the first time the user has used it today it will be a blank entry form because there is no record for today created. The user can just type data into the blank form and close it. On the form closing event I want it to run a tableadapter.insert(username, date, x,x,x).

If it starts a second time it will load showing today's entry because today's date was inserted previously when they closed the form. So this time when they close the form I want the form closing event to just run a tableadapter.updateall(dataset) command. I need some help with my form closing event...

IDE :: Dataset Code Behind Datatable.ColumnChanging Event Firing / But Dataset.HasChanges Property Not True

Jan 28, 2010

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
