• Dan Rooney filling a bitvector32 in a loop

  Dear all, I can fill a bitvector32 like this: Dim InBytes As Int32 dim i for i = 1 to 1000000 InBytes = i 'for example Dim InBitVector As New System.Collections.Specialized.BitVector32(InBytes) next i and then I can read out the individual bits (need this for a graphics conversion). Problem: this gets VERY slow, and I trailed that to the Dim InBitVector statement. Is there ANY way to assign an Int32 number to the InBitVector WITHOUT using the dim statement Thanks, Kees Hmm, odd. It shouldn't make any difference and it didn't when I tried it. There is however a huge difference between running the release mode or debugging with the IDE, ...Show All

• Rush hour Explorer's Send To

  Hi everyone, I'm currently working on a very importent project, and I have a problem. On the explorer, when you right click a file, on the context menu, you can choose the "Send To" submenu, and there there are options.

• Mazzie datetimepicker control

  Here is my dillema, I am trying to create a function with a button to open a hidden datetimepicker, once the date has been selected then hide it again.

• siyou Help with Oracle data access

  Hello, i am totally new to VB development, and have been stuck for a few days with a particular problem. As you will see from my code (which is very basic), I am trying to read data out of an oracle DB and trying to display it on screen. I thought maybe my problem was with my oracle connection but I now know this works fine as the insert statement (its now commented out) seen in the code does indeed insert to the db as it should. I really hope someone can help with this. im guessing its probably something fairly amateur I am doing wrong. Here is my code: Partial Class logOn Inherits System.Web.UI.Page Protected Sub Page_Load( ByVal sender As Object , ByVal e As System.EventArgs) Handles Me .Load End ...Show All

• Philip Wagenaar - Nashuatec System.Drawing and Scaling.

  I've been experimenting with graphics and I want to scale image up and down. I've done this with graphics and scaling transforms and I have a problems. The resuls are beautiful interpolations but that not what I am looking for. In its displays, Photoshop displays pixels, not magnified interpolated contents. As best I can see and guess, in Photoshop when you are looking at an image displayed as 200 percent of its original size, it's look to me as if one pixel is replaced by four identical pixels (two on a side). Is there a way to do scaling in this manner instead of all the interpolation Andreas Johansson wrote: Spidermans_DarkSide, you are always free to reply to any question you want.

• lamont_23 Current Line Colored by IDE (VB.NET)?

  I was wondering if anyone knew a way to make it so that the line the cursor is currently on could have a different background color from all the other text. It greatly increases visibility and ease of use (anyone who has used a text editor like TextPad can attest to this being quite useful when you have huge nests and you want to, for instance, paste right at the line the cursor is on). I don't see any options in the IDE, but maybe someone has made a plug-in Thanks. Oh, I should note that I'm using VB.NET and VS 2005. Currently there's no way to do this in the IDE. I'll pass your suggestion on to the team that handles the VS Editor. Best Regards, ...Show All

• Obrzut Need Help Simplifying

  I want to port a VB6 app to VB2005 while simplifying as much as possible. The current program uses multiple random access files to store data, both for user options and individual companies that are independent projects. My question is about converting multiple complex user-defined types into structures and then saving them in two files-- user options and company-specific. This is what I intend doing but would appreciate suggestions on a better way. 1. Create structures for the types, combining as many as make sense into single structures. The user options will be one structure. These structures must be available throughout the entire application. 2. Create a collection of company-specific structures. There is one collection for each ...Show All

  Hi, I have a long file, and I want to make it smaller. How can I do it zip it http://www.winzip.com/ if you mean in code with API, then http://www.sharpziplib.com/ else shell to a command line or http://www.7-zip.org/ endif .net 2.0 has ZIP libraries built in... 2mb That's nothing. I guess it depends on the target computers, but most modern computers have hard drives of 40gb or more. Ultimately you will need to rely on users deleting what they don't want to keep. Alternatively offer an "archive" function like Outlook does, and soon as they use that option it ZIPs up all the files. If you want to create your own compression algorithm ...Show All
