View 2 RepliesI have been able to use my.resources perfectly, no problems at all. all of a sudden, i try to use resource (i have done EVERYTHING EXACTLY the same as the way i have been using for the last 1 and a half years) and i get an error saying the file does not exist. its there, i only need to type my.resources.s and it already selected the resource i want. it says the file doesn't exist. why? also, the resource is called settings.dat. could that be the problem, don't think it is. i even tried a picture, but it still says the file doesn't exist.
It says: Could not find file 'C:Users[username removed]DocumentsVisual Studio 2008ProjectsdiskSaverdiskSaverinDebugSystem.Byte[]'.
I worked out a way around it (i worked out how to use my.settings in stead), but i haven't worked out why my.resources won't work.

View 3 RepliesThe following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.
