View 2 RepliesUnable To Close Serial Port After USB / Serial Converter Disconnected
Mar 28, 2006I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.
When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

View 4 RepliesRecored Arrow Keys And Then Tell Computer To Enter Arrow Keys?
May 23, 2010So I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.

Dec 5, 2010I am currently creating a program that outputs an image, but the image being outputted consists of text and other graphical elements.

View 6 RepliesPutting Data Into DataGridView In .Net?
May 5, 2011I need a little advice in manipulating DataGridView in Visual Basic .Net. This is my first time playing with DataGridView. My program is to load a .txt file containing data of every room in a building and display them in the DataGridView. Here is a portion of the file showing 2 rooms:
1;1812;1812;F18;T1;26808.16;.00;.00;.00;.00;.00;.00;
1;1813;1813;F18;T1;24000.00;3500.00;.00;300.00;.00;.00;.00
A room is a one-line string that ends with an endline character.I have no problem with loading the file and getting all these information. I store data of each room into an object of class Room, and put them in a list.Right now, I put all of the properties of the room into the data grid's columns like this:
Now, how can I put all these rooms' data into the grid? I tried follow [URL].. at first, but setting DataSource to a list of class Room imitating from the given link doesn't show anything in the grid view.How can we tell the program to link rows of the grid to a list of objects? Or am I doing it wrong?

View 11 RepliesPutting The Comboboxes In A Datagridview
Apr 2, 2009I have a vb.net window app that has a number of combo boxes on it. These are being populated from a number of XML files and all this works like a charm. The problem i have is when it comes to putting the comboboxes in a datagridview. I have set up my columns and have set the first column to be a combobox but i'm having problems referencing this so that i can set the datasource to populate it.
I've looked everywhere but cant seem to find how to reference this control. Once this has been selected it will populate a second combo box based on the data from the first. I think i can sort this out, if i could only work out how to set the datasource of the first combo programatically.
