View 10 RepliesTrying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.

Dim Mapy As Integer = 2000

Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?
View 2 RepliesI guess thats what I need to do, Im trying to allow the user to right click on the top of my form, and my custom Context Menu Strip is displayed, not windows context menu strip. I guess somehow i would need to get the size and draw a rectangle on the non client area and see if the user has right clicked in that rectangle? if so how would I get the area of the non client area?

View 3 RepliesI am trying to scan images in VB.NET. I searched this site for almost an hour and found questions, but little in the way of answers, but some redirection which did not resolve the issue.
I downloaded the example here [URL] which has 7 projects doing a whole bunch of things. I do not have the scanner attached to my PC. Nor can I run any of these examples which do way more than I am trying to do. Then I went here [URL], found the VB version on planetsourcecode, but it will not run. I tried to duplicate what it does, but I couldn't get either of these line to be recognized:
Imports TwainGui.vb.TwainLib
Imports TwainGUI.vb.GdiPlusLib
I understand that the differences between .NET and VB are huge, but what I fail to understand is why no one has been able to post an example of how to scan? My company is not willing to purchase any 3rd party tools and my boss believes it can be done through the api, which some posts seem to imply but fail to show how.
is there a way to add a progressbar to the scan button?i watched tons of videos and i cant figure it out

I am working on a small music player software that runs from the thumbdrive and does not need to be installed. The problem is that when ever i scan the directory for files, it will not scan unless I am running it on a computer that has previously compiled the code.
