• etones Starting apps at shutdown

  I am writeing a simple app that displays a message telling the user to turn off the moniter etc before the user shuts down the system. Could someone exlpain how I can run the app at shutdown. The app also has to be iinstalled on a large network, is there anyway of installing it on all the machines at once. Thanks Hi Rob, Take a look at the ClickOnce delivery system. It's designed to enable applications to be installed from remote machines as and when they are updated. I am unsure as to what style of application you are creating, but if you can have a form loaded in it, a simple way to detect a system shutdown would be to handle the FormClosing event and check the value of the FormClosingEventAr ...Show All

• sujazach bubble sort in a list box

  OK, from what I understand, I would be better off trying to sort numbers in a bubble sort in my listbox. I used the listBox.sorted = true but that does not sort larger numbers correctly., What is the code on this bubble sort and do you just call it in a subroutine Here is the problem with the sorted list command. It does not work correctly with numbers. If you have a numeric list, and the numbers are bigger than 9, or have decimals in them you are out of luck. This is something that MS needs to address in their next code upgrade. Having a single line call for a bubble sort or other types of sorts, be they numeric or whatever would be great. I will try the other thing and see if it works. ...Show All

• Christoph_S VB 2003 & .Net 1.1 - Data Write/Read Issue

  Hi, Working upon an embedded application and have conclusively found the following issue. I have an application that was written before in VB6 that has been upgraded successfully to VB.Net 2003. All issues resolved except the following. Previously, we used the Win32 API to make data writes to a logical disk upon the PC. With the current code, we have upgraded to use the FileStream .Net approach to make all data writes and reads. For interest sake, this is an embedded application that keeps some data in a specific logical drive. The issue is as follows, when I power off the PC and power on, the data is being trashed upon the logical drive where it is being written. I am almost certain that the VB.Net approach we have imple ...Show All

• arturm Feature Request: Regions Allowed In Method Bodies

  It would be really handy if regions were supported within method bodies. I've been using a "design-by-contract" style approach and I would like to be able to put my method's pre-conditions and post-conditions into regions. We're just a bunch of volunteers here, trying to answer questions. We don't get to change .NET or the IDE (I wish). A suggestion like that is best given to the MSFT developpers directly. Has been suggested before but not a very high priority at MS. I really wouldnt hold my breath about it making its way into the product and time soon. but obviously making the suggestion as well adds weight to the suggestion and increases its likelyhood of being implemented.   &nbs ...Show All

• torvaldson Error message: module containing it is not loaded in the debugging session

  Hi I've been having the same annoying minor problem ever since I started using VB.net and was wondering if this is just a feature or whether there is a way round it. The issue I'm having seems to concern shared members of classes. When I try to access one of these member variables or functions to see what their current value is at run time (F9), I get the error message: <membername> is not declared or the module containing it is not loaded in the debugging session.

• warning9 How to set a control's visible property.

  I have a form that has a combo box with 7 items and also has 7 group boxes. Basically, I would like the user to click an item in the combo box and have the corresponding group box appear. If the user clicks a different item in the combo box, then I want the visible groupbox to become invisible, and the new corresponding groupbox to become visible. Could someone help me out with the code Sorry guys, this has been covered in another thread. Yes, the Groupboxes do get put inside one another so you need to keep them separate in the designer and set the location programatically. This works fine but is a real pain when you're designing a busy screen! Rich You don't hav ...Show All

• RobertMcNair "Bad Sequence of Commands" FTP Error

  I'm getting a strange error in my VB FTP program. It works fine when I download a file from an FTP server, but the second time that I download the same file i get "503 Bad Sequence of Commands". If I download one file, download 3 other files, and then try to download the first file again, I get the error. If I close the program and open it again, the error is gone when I try to download the file. Is there some command that I need to send the server to unlock the file or something Yes it fixes the problem but it forces you to open and close the ftp connection for every operation, which is not acceptable when you have multiple operations to perform :-( This problem occurs only with a Unix f ...Show All
