week 7
Drop Downs and updates
Some times we will want to enable our users to select an option from a drop down box, this could be for something like a size of a drink or the colour of
clothing garment.
So if we look at the code above the following actions are happening, the value of the imagebox TeeImage.Image will be set to the location of a file set out in the ( ) the path is selected then the value of the selected option in the drop down box "ColourList.SelectedItem" is pasted in to the path name then the final part is added "t.bmp"
Designs and Designing Tools
We must remember when creating a system the importance of our design documents, these will provide the basis of infomation that will assit the users and also
the developer, as in some cases you may only design a system and never create it as a specailist person may do that for you. However they will need as much information
as is possible to get the correct naming of tools and the correct setting of properties and attributes.
The use of a storyboard is the first step to a healthy project. This provides the detail to location, size and presentation of the system, this is like the architects
plans to a house before it is built. At this stage a desiger could find that a client would like to change the layout as they didnt like the feel of the program, or
they could add further elements to it. It is also key to do this stage first as this is more time efficent that creating the application on a conversation as
you can simply rub out an element and move it elsewhere in seconds and not have to worry about its links to other elements in the system.
Table of Tools
In this area we outline the tools that will be required on the form/ program and the naming of them and if there are any special properties that need to be changed or selected. The best way to present this information is how it has been displayed in your tutorial worksheets todate.
