I was just wondering how I could send commands to a tabbed browser. Such as navigation. I know of webbrowser1.navigate, but that will not work with the tabbed browser. I would also like to use an commands to automatically login. But I am not sure how I could do that in a tabbed browser either. Webbrowser1.document.getelementbyid does not work for this.

View 19 RepliesProvided the following
vb.net Private Function isBlue(ByVal aRGB As Color) As Integer
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then
[CODE]....
I use it with the following:
vb.net Dim count As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
For x As Integer = 10 To 16
Works great. Takes a small square and tests for the blue color indicated by the aRGB value.
What I am trying to do now is test for all Black (as opposed to blue). I want to copy that isBlue Sub to a "isBlack" Sub and perform a like test, but I do not know what to use for this part:
If aRGB.R < 30 And aRGB.G < 30 And aRGB.B > 170 Then explain those values and what changes to each one does?
I've edited the code some:
vb.net Dim bluepixels As Integer = 0
Dim blackpixels As Integer = 0
Dim img3 As New Bitmap(DirectCast(CameraTable.Controls("camera" & z.ToString), PictureBox).Image)
[CODE]...
And in the sub I am testing for an R, G, and B value less than 3 (black should be all 0's) I'm still interested in how to manipulate those RGB values to test for other colors, or very specific hex colors.
When i run the debugging tool for visual basic my computer crashes (Blue screen). it's rather constant with the VB forms, even ones without code at all... Any help on the matter?

View 4 RepliesI use VB2010 Express on a Win7(x64) desktop. I use the following code to select items from data listed in a ListView and then save the selections to a database when I have finished choosing. I use the following code
[code language="VB.NET"] Private Sub ListView1_Click(ByVal
sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click
Dim z As Byte = ListView1.SelectedItems.Item(0).Index
Dim n As Byte = 0

Each time I click on an item in the list, that item is highlighted in Blue. When I click on another, the highlighting transfers to the new item and the previously selected item is green. The HideSelection has no effect on the highlighting, nor does transferring the Focus to another control. How to get rid of the blue highlighting as the only way I have found is to click in the listview control below the data which is counter intuitive.
I have three HScrollBars(for the colors red, green, blue and maximum to 255), a picturebox(to see the output color) and a textbox which gives the color in HTML output. For example: 0xE60000FF >> This is a red color.I know I first should make a code and paste it here, but I really don't have any idea how.
View 12 RepliesI was attempting to clean up my serial port example that is in the code bank. I had decided to use a modem, thinking that a lot of computers still had them. By using the loopback feature of the modem I am able to simulate / emulate various features of the serial port.All was going well, and then I got a Blue Screen with this error after running for 10 minutes or so:DRIVER_IRQL_NOT_LESS_OR_EQUALSTOP 0x000000d1 etc.I then went back to using my GPS receiver, which sends messages constantly to a serial port. This test ran for several hours(4). It received messages correctly during the entire test.I then created a new, not as complex, version and it also receives the Blue Screen. I have made sure that the modem drivers are up to date, searched for the error, etc. My gut is telling me that it is the modem driver. I have attached the project. This is the scaled back version, but it uses the same functionality.
View 7 RepliesI am developing a simple application in VB10 that uses ADO.net to store data in an Access database, and gets input via a serial port RS232. It works well, but is not fully debugged. Unfortunately, a problem has recently started where as soon as i close the program I get a blue screen. Makes it hard to debug. The solution does not even have to have run; it just has to have been loaded and then exit VB10. The blue screen aslo happens to most of the other example solutions that I have downloaded.
Questions:
1)How do you capture the STOP error codes (probably stupid question)?
2) Is there an easy solution that rings a bell? My IT support is trying but not getting anywhere. Have to believe it is hardware related, but the hard drive checks out with testing.

View 4 RepliesI have a form with a lot of LineShapes on it, and basically what I'm trying to do is make certain lines a blue colour and others a black colour, depending what it's in an array of integers. Each line is called line1, line2 etc. So if one of the values in the array is 3, then line3 would be coloured blue.
I have the following code to handle all the lines more easier:
MeterArray = New PowerPacks.LineShape() {line1, line2, line3, line4, line5}
However, since I'm going to have about 50 seperate lines, this is going to look quite messy when I reach line50. So my question is, is there a tidyier way of handling these lineshapes.
He wanted to know how they can do to convert a portion of the form that you see only blue or black and white. I mean, the user presses a button and all that is in the form sees only blue or black and white only.
