• Muhammad Usman Khalid How can I cycle through all the System.Drawing.Colors?

  I worked out the Console version to cycle through all 16 available colors: Sub Main() Dim x, y As Integer For x = 0 To 15 Console.BackgroundColor = CType(x, ConsoleColor) Console.Clear() For y = 0 To 15 Console.ForegroundColor = CType(y, ConsoleColor) Console.WriteLine("Background: {0}; Foreground: {1}", x, y) Next y Console.ReadLine() Next x Console.ResetColor() Console.Clear() Console.WriteLine() End Sub I also worked out a program that cycles through 4 colors in a Windows form: Private Sub btnCycle_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCycle.Click Static x As Integer x = x + 1 If x = 5 Then x ...Show All

• Ron L How to compare grapical (bitmap) data?

• Kiranvukkadala Compiled app failing in InitializeComponent

  I have created a WinForms application that runs fine in Debug mode, but when I deploy it to a server, it fails when it executes InitializeComponent while loading its first form. How do you debug something like this Have you signed the assembly What's the exception that you get Winforms Err.Number and Err.Description are not VB.Net errors They are VBA, VB, or VB.Script style errors I believe. So this error is probably comming from a VB based Com object that the application is attempting to initialize. Thats my guess anyway.

• wazimu Class not registered

  I just transferred an app from one computer to another and upgraded from VS 2002 to VS 2005. After doing this, I'm getting several errors, the most common one being: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). The error occurs on the line that says InitializeComponent() at the end of the region "Window Form Designer generated code" for one of my forms.

What do I need to do to register this class Hi, Tools->Options->Debugging->General : Enable just my code I have that active and can break and step into InitializeComponent, so I gue ...Show All

• NemanjaTheLost VB .net tab control multi line...

  Ok, I am creating a new version of a program in vb .net. The main page has a tab control with 7 tabs on it to select your general category. However, the two word text does not always fit on these tabs. I want the text to wrap instead of just going out of view off of the tab. However, there is no wrapping option or way to get the text on multiple lines(like there was in VB 6), except for forcing it by inserting a new line character into the text. But if I do it that way the text is no longer vertically OR horizontally centered and looks very bad, and is plainly unacceptable. So, is there any way to get the text on multiple lines on the tab control I have been looking everywhere for this option and it is simply not there. Thank you. ...Show All

• Rafael Mores Excluding weekends in DateTimePicker

• joejoejoeoejoe Have an application get it's own checksum?

  I need my application to get it's own checksum, so i have a class with a hashing function that i can use but i am not sure i can just use file I/O to open this file then hash its contents, then even if i could, i'm not sure how to open the filestream so yeah i need some suggestions for getting an application to get a checksum of itself. These are good questions. I think the first thing you need to try is to open the assembly if possible "read-only". As long as you are self consistent in your calculations I don't think it will make much different. I think I might avoid checksumming the header. I don't remember if there is any changing information in it. ...Show All

• davehomebrew DatagridView scrollbars

  Hi, I really need help on this one. I have a DatagGridView which has its scrollbars for both horizontal and vertical which can fit around 6 rows before the scrollbars show up. The Form hangs when the vertical scrollbar shows up. My application works fine when im just running it on debug but when im testing it on a published exe, it hangs when the vertical scrollbar shows up. Please any help or ideas will be very much appreciated! Thank you so so much! Stanley Rain3204, The different results between your debug and publish depends on your program running environment.

• chadmv Need suggestion on control to use

  I would like to have a control that has columns & rows. Each row will have a button associated with it. It won't be tied to any data source. I've looked at the DataGridView control, and it seems like the steroid version of what I want. I don't like the gray column it has on the left side of it that tells me which row is selected. Also, I know I can make a column a button column, but I don't like that it shows as a column in itself. Is there a more basic kind of grid Thanks! Checkboxes are standard. Yes for images. Take a look at this: www.freewebs.com/reneecc That's a listview on the right. The listview won't allow me to add a button (or an image) for the user to click on for each ro ...Show All

Thanks Any mention of off topic item was evidence and reasoning for this on-topic question. There is nothing different about the environment for compiling 64 bit. Its really only a compiler switch.
