For some reason my text did not post with the code - so here it is! I am finishing up a class in VB and would like some assistance in a program. I need to do the following: the user needs to select a drawing tool, line color and line width (have these displayed in comboboxes). when they click draw they can draw using the selected items and with the drawing start with mouse down and end with mouse up. I am able to get a drawing in the picture box,... -

entering file contents into an array
I am a student finishing a class in Visual Basic, and would like some assistance with a program I am working on. I need to read the contents of a file (showing makes of cars on one line and a daily rental fee on the following line) into an array and then display the file contents in a list box. The user then chooses the car he/she wants to rent. I then need to obtain the rental fee from the array and use that value to calculate the total rentals.... -

problems with enhanced button control
I am using Visual Studio.NET 2003 and have built a enhanced button control (enhbutton) to capture the number of times the button has been clicked. I did the code and did a build. I then added a test program (buttontest), added the enhbutton control and set buttontest as the startup program. I cannot get the number of times the button is clicked to display on the face of the button. A 0 is put in by the enhbutton code as the starting point. My code... -

Thanks for your help! Please accept my apologies for posting to the wrong forum. I use both .NET 2003 and VB 2005 and sometimes get confused! I will also post to the correct forum. Again, my thanks and apologies....Leave a comment:

format for datetimepicker
I am working on a program where I have two datetimepickers and need the difference in days between the two dates. I have the format property for both set to short. When I add the datetimepicker to a label it prints as 12:00:00AM instead of as a date.. How do I format this to return tghe day of the month selected in the picker?
Dim d1 As Date = DateTimePicker1 .Value
Dim d2 As Date = DateTimePicker2 .Value
... -
I have now got the text names for the labels to be filled in by the control when the test program is run. The problem now seems to be with the code I have for the total number of days between the datetimepicker1 (date1) and datetimepicker2 (date2). In an attempt to find the problem, I selected date1 to print and got a value of 1200 AM so apparently need to do a conversion somewhere to get just the date. The code is below:

VB.NET: testing a custom control
I am having difficulties getting the date interval to calculate and to get the text added to the labels. I know the code in the test program works if I get the total days, so the problem is with the code for the control. When I print Date1 I get 12:00 AM but cannot seem to get the datetimepicker to use dates in the calculation.
Thanks for your willingness to help!
