• Ross Watson Custom Button Control flickers - Paint event gets fired continuously

  Hi All, I have a custom button control in VB 2005, ported from VB 6.0. I faced many hurdles before i got it working with all the functionalities that it had in VB 6.0. I draw the graphics of the button in paint event. I need clarifications on the following things. 1. When there is a change in property. example the text property, it needs to be reflected in the control. So i call Invalidate method. Is it the right way to refresh the button 2. This button control works fine when there is no change in the form that uses it while running. i.e. What i mean is, if there is a label in form that updates the timer count down, the custom button control received paint event every time the label in the form that also has this control chang ...Show All

• Luis Esteban Valencia Muñoz Secure SQL Login Info

  Hi, I am currently working on a program that will connect MySQL database using MyOLEDB Driver. I used Dim fdCon As New OleDb.OleDbConnection("Provider=MySQLProv;Data Source= DATABASE ;User Id= USERNAME ;Password= PASSWORD ;") I am wondering is it secure to hard-code the username and password If not, how could I secure these info Thanks in advance! No, it is not secure... Ideally you should prompt the user for these the first time your application loads and then store it using DPAPI. If you search around you'll find a few DPAPI libraries for .NET. Also, have a look at the Configuration Management Application Block/Enterprise Library which supports encrypted configuration ...Show All

• Richard Meyers "Cannot create ActiveX Component" when run from a service

  Hello, I've been having this issue for a little while now and it's getting to be a bit of a headache. I'm writing a service that calls a DLL, that DLL uses the CreateObject statement to call an application, Cognos Impromptu. Cognos provides no API for its app, only macro scripting, thus I have no Import statements or references. Upon running the service, once it reaches the CreateObject("CognosImpromptu.Application") statement I get the error "Cannot Create ActiveX Component." However, I am able to create other ActiveX objects, such as Internet Explorer, so I don't know what the problem with this program would be. For a further explanation please refer to the thread: http://www.vbforums.com/showthread.php p=2619238 An ...Show All

• numberOneFootballFan why path = path??

  Hi all, I am studying 70-536, that's why i have so many questions.... The System.IO.Path allows us to work witl file system's path, but why i can change extension of a file with Path class doesn't make a lot of sense... Thanks, Alan, Hi, The Path class is designed for working with file path strings, whereas File class is used for manipulating physical files. The Path.ChangeExtension doesn't really change the file name in the file system, it only replaces the portion of the path string you're working on. And a file name is a part of the file's full path... Andrej Firstly look at the following documentation System.IO.Path Class http://msdn2.microsoft.com/en-us/library/syste ...Show All

• Jawad Naeem Passing arrays from vb .NET to ActiveX control (*.ocx)

  I have an application written in Visual Basic 6 that uses an ActiveX control written in Visual C++ 6. I'm moving the visual basic 6 application to visual basic .NET (2003). The problem is when I try to pass an array from the visual basic code as a parameter of a function of the control. In Visual Basic 6 the code is something like this: Dim dummy(10) as Long '... 'some code '... myActiveXControl.myFunction(dummy(0)) myFunction expects a reference of the first element of an array of Integers. Passing the first element of the array works fine in visual basic 6. But if I try the above code in vb .NET, changing the definition of the array for this one (type Long in vb 6 is Integer in vb .NET) : Dim dummy(10) as Integer ...Show All

• Rohit Tela Can you mame your own attributes, or whatever they're called?

  I'm new to VB, and I was wondering, when you click and drag a button or something on to a form, and it has properties or attributes, or whatever, like button size, what it says, etc. Can you make your own field for something like that Thanks. A control such as a button is a class. Some classes are inheritable which means you can use these as the basis of a new control inheriting all there functionality and then adding to it. For these you can add or modify the existing class functionality. For these you can add your own properties, methods and you could create you own attributes but for what you talking about its probably more likely to be methods and properties you'll want to add. I'd probably lo ...Show All

• mikag Process not completing

  I have a vb form that runs a command line executable that creates a diff file from two existing files. When I run the program from the command line it creates a 419Mb diff file. When I run it as a process from my VB program it gets to ~400 Mb and stops. If I kill the VB program the command line executable continues to run and finishes the diff file. So I have 2 questions. Why does the process stop before for it finishes when I run it inside vb Why does the program continue to run when I kill the VB app. Here is my code Private Sub xdelta( ByVal strFile1, ByVal strFile2, ByVal strDelta) Dim strError As String Dim p As New Process Dim info As New ProcessStartInfo info.UseShellExecute = False ...Show All
