Visual Basic Runtime Error 1004
Error Types (Visual Basic) Visual Studio 2015 Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 Visual Studio .NET 2003 In Visual Basic, errors (also called exceptions) fall into one of three categories: syntax errors, run-time errors, and logic errors.Syntax ErrorsSyntax errors are those that appear while you write code. Visual Basic checks your code as you type it in the Code Editor window and alerts you if you make a mistake, such as misspelling a word or using a language element improperly. Syntax errors are the most common type of errors. You can fix them easily in the coding environment as soon as they occur.Note The Option Explicit statement is one means of avoiding syntax errors. It forces you to declare, in advance, all the variables to be used in the application. Therefore, when those variables are used in the code, any typographic errors are caught immediately and can be fixed.Run-Time ErrorsRun-time errors ar
for Beginners Runtime errors in VB .NET This lesson is part of an ongoing tutorial. The first part is here: Design Time Errors Runtime errors are a lot harder than Design Time errors to track down. As their name suggests, these errors occur visual basic runtime error 6 overflow when the programme is running. Runtime errors are the ones that crash your programme. A simple way to visual basic runtime error 32809 crash a programme is to divided by zero. Change the code for your button to this, and try it out: Dim Num1 As Integer Dim Num2
Visual Basic Runtime Error 9 Subscript Out Of Range
As Integer Num1 = 10 Num2 = 0 TextBox1.Text = CInt(Num1 / Num2) The CInt( ) part means Convert to an Integer. We're just making sure to convert the answer to the sum into a number. But run your programme and test it https://msdn.microsoft.com/en-us/library/shz02d41.aspx out. Click your button and see what happens. What happens is that you'll get the following error message popping up: If you have started your programme without debugging then the error message is a little less helpful: Stop your programme from running to get rid of any error messages. When you try to divide by zero, VB.NET throws up the Overflow error message - there would be just too many zeros to go into the Integer variable type. Even if you change the Type into a Single or http://www.homeandlearn.co.uk/NET/nets5p3.html a Double, you'd still get the same error message. Programming environments just don't like you dividing a number by zero. If this were in a real programme, chances are it would crash, or "bug out". And you'll get the blame! If you think the answer to a calculation could result in zero, you should check for this. We'll see how to write code to trap Runtime errors in a moment. But here's another example of one. From the controls toolbox, add a RichTextBox control to your form. Change the Name property of your RichTextBox to rt1. A RichTextBox is just like a normal textbox but with more functionality. One of these extra functions is the ability to load a file directly. Delete or comment out any code you have for your button, and add the following line: rt1.LoadFile("C:\test10.txt", RichTextBoxStreamType.PlainText) All the line does is to load (or try to) the text file called "test10.txt" into the RichTextBox. The second argument just specifies that the type of file we want to load is a Plain Text file. Run your programme, and then click the button. If you don't have a text file called "test10.txt" in the root folder of your C drive, you'll get the following Runtime error message: The additional information is quite useful this time. It's saying that the file "C:\test10.txt" could not be found. If the error occurred in a normal programme, it would shut down. Not something you want a programme to do in mid stream! But let's see how to deal with it. In the next

understand statements with syntax errors (just as you cannot understand sentences with grammatical errors), it is able to detect them as soon as you write them. The following subprogram has three syntax errors. As you see, the syntax errors are indicated by a squiggly blue line. If you move the cursor over the blue line, the VB.NET development system displays an explanation of the syntax error, as shown below. In this case, the error message states that the programmer has not created an object called "labelone." The programmer probably meant to type "label1". In this case, the error message states that Labels do not have "Tuxt" properties -- the programmer probably meant to type "Text". In this case, the programmer is attempting to assign a numeric (integer) value to a string property. The programmer probably meant to type "14". Syntax errors are easy to find and correct because the development system finds them for you. If you write a statement that is syntactically correct, the computer will understand and execute it. However, if you accidently told it to do something that you did not really intend, you would have made a logical or semantic error. For example, if a programmer accidently multiplies two variables when he or she meant to divide them, the program will give an incorrect result, but no error message. Syntax errors are errors of grammar; whereas, logical or semantic errors are errors of meaning. Run time errors are detected while the program executes. These are often discovered when the user enters illegal data. For example, if the user types in a string when the computer expects a number, there will be a runtime error: When running a payroll program, the user entered "ten" instead of "10" for the hours worked. When the computer tried to multiply the pay rate by "ten", it generated the error message shown above. Since the computer cannot generate an error message when you make a logical error, they are generally hardest to fix. Patiently stepping through the execution of the program will often help you find your error. We will also see debugging aids in the development system.
