Recently I've created a window database program(Tools Inventory); everything works fine except for the following two :
1. It doesn't accept modifications to the existing datas in the column & rows. (Error : Updates require a ValidCommand......)
2. Remove button does not delete the data in the database. It only works in the runtime.

I want to make a program where I load in a file in hex format and have a number of check boxes where if selected then certain hex values change.
So it would search for offset d5dc and change the last 4 values to 00 E1 F5 05 and then then same again for other check boxes with different offsets set to each one.

On my add button i still have to add codes that disables my navigation buttons and and my search button... and add codes that will enable them in save button... im still new thats why my codes are just simple if, else if, else conditions that just manipulates enable, visible, text, properties..also if i search my data will be search but my textboxes only shows the searched data.. i still have to add button that will only be visible if the program finds a data... and this button function is to remove the filter..rather than disabling some functions i want a messagebox to prompt the user that this functions arent functionable...
Look at my codes... i find it lame... its kinda irritating always just using True and false..

I have been using Visual Basic for about 2 weeks now so I know I am getting in over my head at this point, but times a factor. I have created a user form with around 100 User entered text boxes and pull down menus, tabbed pages etc. I can create a distributable file with no problem. However I cannot find any kind of example, tutorial, etc that will show me how to allow an end user to save the form as "enterfilenamehere.DCP" (for example) and then reopen any .dcp file created in my form application. The only examples and tutorials I can find are how to type text and save it as a txt. format. Could someone lend a complete novice some advice or point me in a good direction on where to learn about saving and opening custom file types?To clarify The user can use my form, But at this point has no way of saving and recalling what they entered in my form. It's a one time use only...not really what I want.

My code is this:
Me.Validate()
Me.CFTINVENTORYBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(CFTDataSet)
At first I can insert data into the cells and save it... but when I try to edit the same cell with data already saved in it I get this error...
sqlcelexception was unhandled
There was an error parsing the query.
[ Token line number = 2,Token line offset = 29,Token in error = , ]
I also get the same error when deleting an already saved cell with data.

Is there a way one can edit sound, say for example you have an mp3 sound it is 12sec long, but you want to fit it into 10sec. is there a way one can write a code that automatically adjust the sound so that it only play faster and save it as mp3 again? I am not talking about existing programs to do it. rather a standalone app?

So I have a list of names in a .txt file. Where is a place I can type in all the names I want and press save and get a link so they can see the list. Then I can remove a name and press save and the name will be gone. And or add a name. So basically I need a website where I can type something and keep it uptodate. I've tried ripway but after you edit the list and save it it doesn't change.

I can launch Excel with the document I want using VB.Net 2010:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.xlsx"
p.Start()
Excel starts OK with the file opened. I edit the file, but when I close it down, Excel doesn't ask if I want to save changes. So it closes and loses my edits.
If I do the same with a text file:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.txt"
p.Start()
It opens (in Notepad++), I edit it and close it, and Notepad++ asks if I want to save changes.
I've now tried similar code with a Word document - and that's OK. Also with an OpenOffice Sheet document and that works as well.
This behaviour is happening in Windows 7 with Excel 2010. It works as expected in Windows XP with Excel 2007.
What am I doing wrong with Excel? Is it me?

The gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
