View 11 RepliesI'm trying to develop a program structure in very broad terms. At this point, the Forms used do nothing but call other Forms and allow for their closure. After startup and initialization activities, I want the user to set up options and run the program. The program can be run again (click one button) and again with the same options, or (click another), the options can be changed for the next and subsequent runs. Clicking a third button will cause shutdown activities to be performed.
Sounds pretty simple. However, I get the options form the first time, but subsequent ShowDialog calls cause the form to pop up (I detected a Load and an Activated call) for an instant, then disappear, and the program rolls on without permitting option selection, even though the key variable NewSetup is definitely True.
Code:

I'm using Visual Basic 2006 and i'm a newbie so excuse me if my question is not complete. I basically have a picturebox, in which i am displaying an image from a webcam. Now the user clicks on two points on the image and i need to get the distance between the two points in terms of the number of pixels. I did think of and try the pythagorean theorem, but i'm confused as to what units the answer turns out in. Is it in terms of inches? or pixels? Do i need to set the Scale Mode propety to pixels to get it in pixels? And if so, is there a way to get the number of pixels per inch? Sorry for asking so many questions but i've been reading other forums and i'm confused!
View 12 RepliesI'm in the process of moving from ADO.NET to Linq. The application is a directory search program to look people up. The users are allowed to type the search criteria into a single textbox. They can separate each term with a space, or wrap a phrase in quotes such as "park place" to indicate that it is one term.
Behind the scenes the data comes from a XML file that has about 90,000 records in it and is about 65 megs. I load the data into a DataTable and then use the .Select method with a SQL query to perform the searches. The query I pass is built from the search terms the user passed. I split the string from the textbox into an array using a regular expression that will split everything into a separate element that has a space in it. However if there are quotes around a phrase, that becomes it's own element in the array. I then end up with a single dimension array with x number of elements, which I iterate over to build a long query.
I then build the search expression below:
query = query & _
"((userid LIKE '" & tempstr & "%') OR " & _
"(nickname LIKE '" & tempstr & "%') OR " & _

I'm just starting to use vb .net (using 2008 express edition) and I want to make a menu for my program that will be like a sidebar that when you click one of the options, a few sub-options will fold out that will push the main options below downwards - and then the sub-options will disappear and the options will go back into place when something else is selected.I am not sure exactly where to start in terms of making those options get pushed down/come back up..
View 3 RepliesDue to the way I currently have it setup, the calculations are not being excecuted properly. I've been tweaking for a while and haven't gotten it yet. I think the problem is that certain equations are being done before certain terms are defined. If I click the calculate button multiple times, it works fine, but I need it to function on the first click.

I added an "edit" icon on my bindingNavigator. When users click on it, a new form will come out and pull out all the data records from the datagridview. Now the strange thing is that when I wanted to edit the data records, when I left the product name blank, I would get an error message saying "Product cannot be blank" - please see above code. But when I left the "Cost Price" blank(same applies to "Sell Price" and "Quantity"), the error message box wouldn't come out, instead, it did not allow me to move on to another textbox, close the form etc until I filled out that textbox with INTEGER. May I know why the error mesagebox would not come out when I entered the wrong datatype?
the testBoolean is set to the value True, but for some reason when debugging, it step through both conditions, so in the end the button1.visble becomes False, but I want it to be set to True.[code]....
View 14 RepliesI am very new to vb, I know there is an error somewhere, I had an assignment which stated that if a number was < 101 or > 500 and the answer is correct the output should be, for example-123, if the answer was wrong then the message output should be wrong number <101>500.

How do I do it?
So I am trying to evaluate 3 conditions in an if statement. Its not working how I would assume it should. I basically want to do this:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 And (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
If I write it in that manner it gives inconsistent results. If I workaround by writing it this way it works perfectly:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 Then
If (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
Endif
What is the proper way to do this with only one if statement?
