View 3 RepliesI wrote program that will send keystrokes to a computer if a button is pressed. The button is wired to a db9 connector and plugged into the pc. The program works, except I can not figure out how to detect if the cable gets unplugged. I am monitoring the CD pin change event to send keystrokes, but if the cable is not plugged in then I need it to send a messagebox.
View 8 RepliesTo object oriented programming and programming with visual basic .net (vb 2008 express). regarding storing of information but not in a database. Someone mentioned using binary or xml serialization. So I researched that and after two long 8 hour days of messing around with binary serialization and about a dozen different code techniques i finally found one that seems to work. I created a module that serializes two variables and appends them into a file. The same module also has a sub that deserializes the information from the file and displays in a message box. If needed I'll provide the code later.
Really the problem I am having is that my message box only displays the first entry into the file and no other. So I can append any number of variables to the file but every time I call the subroutine in my module it only displays the first entry. How do you read all of the file? Also can I search the file for a particular value of a variable? The variables are codependent. The two variables are simply a date and a string representing a changing code that corresponds to that specific date. So I'd like to be able to say search for a date and retrieve both the date and the code.
However I don't have any idea how to do this. Also the messagebox.show method is probably not the best way to illustrate the information in the file but I'm still new and I'm not sure the best way to show all the info in the file. For instance if I wanted to show the entire contents or just the codes corresponding to certain dates. I know a database is probably the better answer but I've gotten this far without one, lol, I'm too stubborn to change now. Once I figure this out, I'll switch and try the same technique with a database.

View 4 RepliesI have tried a number of freely available code converters to convert the following piece, however without success.
Dim resultList = ((From e In p_Xml.Elements()
Where UCase(e.Name.LocalName) = searchName).Union(
From a In p_Xml.Attributes()
Where UCase(a.Name.LocalName) = searchName
Select <<%= propertyName %>><%= a.Value %></>)).ToList()
I think I got it here
var resultList = (from e in p_xml.Elements()
where e.Name.LocalName == searchName
select propertyName).

As I read [URL] For VB: Inside the Snippet element, add the References element and all of the required child elements that add a reference to the project when the snippet is inserted.For C# Visual C# code snippets to do not support the References section, so a reference to System.Windows.Forms.dll must be added to the project manually What fundamental reason prevents C# to support References like VB ?[URL] But it isn't even as full-featured as Code Snippet References as Code Snippet References will allow you to add multiple references at once not just one by one.C# is supposedly more "professional" than VB.NET, one would expect C# to be more featured not more limited or does "professional" means you have to do it the hard way as said "MANUALLY"?
View 3 RepliesThis is a part of my project, my project basically uses a motion sensor to detect any intrusion. So one of the modules is to lock the PC on detection of an intruder. Is there a way to lock the PC using Visual Basic?(Because most of the other modules have been programmed in Visual Basic.)

I am working on a little small 10 question quiz. The quiz is just for fun for a work thing I'm doing. I'm using VB.net. I'd like to put in one of the questions something like "what's your favorite baseball team?" Then list 3 radio buttons for 3 possible answers. But I'd like to make 2 of the radio buttons move away when a person tries to mouse over it to click on it. So only the answer I want them to use would be possible. I can creat it all but the code to make the raido buttons move when moused over. I've been searching but having trouble finding anything on how to do this.
I don't have my actual quiz code in front of me. But can post the form code for that question later tonight when I get home if needed. But the form is very basic. just has the question in a lable, Then the 3 answers below it as radio buttons. I have a next button that goes to the next form and closes the previous one, and an exit button that closes down the whole application.
I need to translate line 4 in the code snippet below into VB. For some reason I cannot get this done tonight. I am either too tired or having a brain drain.[code]

iam currently working on my uni project and i have encountered a problem with valadation section.My system displays a message telling the user to input any fields that they have missed out on, listing the name of the field. However as these IF functions are in order the user must input the data in the order of how it is in the code. for example if the "consweight" is inputed and the calculate button is pressed, it thinks that all valadation above it has occured, when those fields are still empty.
