  I am getting the following error when I close down the dot net IDE.

• Talyrond Compare speed of reading random(binary file) in VB6 and VB2005

  I ever created one project to read a random file(binary, not text) in VB6. It takes only 5 seconds to get all records(structure as below) and store these records in an array, but now i upgraded it to VB2005. I also use the handle-base method(fileget). Very miserable, it takes more then 30 seconds. I do not know why !!!!No any error, but i do not know why so slow!!!!

• Winks Help with subclassing

  Was hoping someone might be able to spare a link or two about refining classes. Working on a newbie program and have a class set up but need to refine it and possibly add a sub class.

• Robert Shurbet Could you tell me the type of your applications?

  Hello. I have a question on user settings. When I install another version of my application on a customer PC I lost old users settings. Could anyone say me how could I retrieve them when I install a new version of my application Thanks... I am assuming that you are using the built in "My.Settings" type of thing with the application properties. I'm curious as well, because it seems that each time you make a 'version change' VB wants to make a new configuration file. It would be nice if there was a "use old version" setting. I also await an answer to this part. :) Hello. The type of my applicacion is framework 2.0 visual 2005. I don't need to uninst ...Show All

• jenjen13 Update DB/Please review my code

  I have an XML file that I have put into a datagrid. (The grid is loading the XML perfectly!) I am now looping through my datagrid to update my SQL 2005 DB. Can someone please tell me what I am doing wrong here (One thing that may look odd is that I am querying the Inventory record first to count the current inventory then adding the column total to that count. That is because the XML file shows inventory at 3 different locations and I only need to know the TOTAL) Thanks in advance! visual basic code: Private Sub btnGetData_Click( ByVal sender As Object , ByVal e As System.EventArgs) Handles btnGetData.Click dsAvailableBatch.

• zariusan Controlling IHttpHandler for thumbnails

  Hi, Hope to get some help on the following issue: I need to display some photos on an ASP.NET page. These photos will first be displayed as a thumbnail (in a thumbnail gallery). When the user clicks on it, it will display the actual size photo in a new window. So far, these has been done.  I've implemented a ihttphandler to get the thumbnail of the photos for display in the thumbnail gallery. However, because some of the photos are partially corrupted, the thumbnail of these photos will not be displayed.  Hence, my question is:  In the case of a partially corrupted photo, how in the world should I tell the iHttpHandler to NOT attempt to extract the thumbnail and instead return the original photo for display ...Show All
