View 3 RepliesIve been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.
The program that I am creating needs to click on an image in a web browser. I have saved a bmp of the image and was wondering if there was a way that I could scan for the image in the webbrowser, and once found send a silent mouse click. Silent in the fact that it doesn't move the mouse. And I would normally use invokemember but the button is an image, not a "button". So I need to scan for it.

Can I can access to web-cam frame events or is there any efficient way to achieve this?
I've searched these forums, and found some GDI and C# links, but I really want to do some image processing in VB.NET.
how I would go about combining 2 bitmaps into one, sort of superimposed on top of eachother? I don't know what libraries are available in .NET.
I am not a CS major. I'm taking Mechatronics.But I'm always leaning heavily towards embedded programming and electronics. Nowadays, I would want to take the dive into PC programming. Slowly.So, I've started to learn VB.net. The syntax and basic programming principles are still ok. But I got stumped when I tried to go deeper where I see, directx, directshow, dll, avicap32, and etc. What are they? and API? How ar they connected with VB.net? It's different when I'm programming microC, where the environment is limited and dictated. Now there are options so broad until I am lost.is the architecture and what has those APIs , DLLS, and etc mean literally.Ultimate goal would be using VB.net to interface with webcam and do image processing.

View 1 RepliesI just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:
Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click
Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
2008 Array Processing and Sequential File Processing
View 14 RepliesIm a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008
Im using a black n white image of a human as my back ground and panels to display the same bits in color when the area is clicked. What isn't working for me is the panels are slightly overlapped and one will always be on top of the other. it is transparent so you can see the back ground, but not the panel underneath it when it has a picture in it.

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
