mwith wrote: But the problem is it has no serial interface. It has a cable with a RJ11 connector. Which fact you did not mention in your first post. So what protocol does it use to communicate with its host? You have also not given any clue as to what software interface is available with this machine. For example what character sequence do you need to send to the cash drawer to make it open?

made me laugh. I was helping this young lady once with word one time. She: Look word won't go onto the next line. She taps furiously at the down arrow ME: Lets see I press return key and it goes onto the next line. She in awe: How did you know how to do that ????

When working with DB try your best to keep it simple. Also, check the SQL statement if Bank_Code and Acc_No are 'int' data types then you need to convert the textboxes from string to int. i.e. Convert.ToInt32(txtBankCode.Text) Good Luck, Jason -- modified at 12:01 Thursday 11th January, 2007 Programmer: A biological machine designed to convert caffeine into code. * Developer: A person who develops working systems by writing and using software.

Why don't you think to write your first article based on this topic? That will indeed be a good start. It is nothing that you have to invent, but find the resources and combine them to form the article (Google or any other search engine/ MS technical site would greatly help you) L.W.C. Nirosh.

Are you actually adding the columns one by one? Or are you just doing: myDataGridView.DataSource = myDataTable I haven't looked at it yet, but couldn't you actually just do: myDataGridView.DataSource = myDataTable.Columns[x], to only show that one column?

Password protecting a folder is extremely inefficient from both a security and administrative standpoint. Networking relies on the users access token to determine what the have access to and what they don't. Passwords are NEVER assigned to specific resources, only user/machine accounts. You have to plan your security more carefully, but it's far easier to manage. Create a group on that machine, add the users that you want to have access to that folder to the group, then modify the permissions of the folder and give the appropriate permissions to the group. Done! Now noone has to memorize yet another password. The users that have access to the folder have it without doing anything and the users who don't, well, don't have access to it.

Just create a member variable for frmNew: private Form2 frmNew = null; private void CreateFrmNew() { if (frmNew == null) { frmNew = new Form2(); frmNew.MdiParent = this; frmNew.StartPosition = FormStartPosition.Manual; frmNew.Location = new Point(0, 0); } frmNew.Show(); } Call CreateFrmNew, it will create frmNew if not exists, otherwise frmNew will be shown.
