• Visual Basic NullReferenceException on splash screen

  Here's one for everyone. I have an app that I am using a splash screen with. In Windows XP it works great, no issues. In Windows 2000 not so much. It throws a System.NullReferenceException when the splash screen closes. I can choose continue from the error and the app works fine, but as you can imagin that looks bad to the end user. As per a suggestion made in a previous post. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=184053&SiteID=1 I loaded vb express on a 2K box and tried to catch the exception. It will not catch, I have it set to break on this exception, it just states a NullReferenceException was unhandled. After looking into the detail, it states that the exception is comming from the System.Windows.Forms.dll. C ...Show All

• Visual C# Class inheriting itself

  Hi All,        I have a very serious doubt of whether a class can inherit itself. Though their is no purpose, i just want to know whether a class inherits itself. I have provided a sample code for you to check that it actually does which very much proves the concept of inheritance to be wrong.   public class Sample  {           public class Sample1:Sample   {           public  Sample1()    {     Console.WriteLine("Sample1 Constructor wihtout Argument");    }        public void a()     ...Show All

• Visual Basic A Windows Explorer-like browser that shows image thumbnails

  Hello all, Don't want to reinvent the wheel so maybe somebody out there has come across some source code that would allow me to reproduce something like Windows Explorer that would show image files as thumbnails when looking in a directory containing image files. Visual Basic's Power Pack has a FileViewer controller that works ok but without showing thumbnails. Any suggestions greatly appreciated. Cheers. NRF To keep the aspect ration, first divide the original width by the original height. Then divide the new width by the result to calculate the new height. You can add this code to a backgroundworker. The easiest way might be to move the two Add() method calls into the progress report even ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DXT compressed Textures

  Hi, in general it looks like there are the same DXT texture compression formats as for DX9. I assume those compression formats do not work with the new DXGI_FORMAT_R9G9B9E5_SHAREDEXP & DXGI_FORMAT_R11G11B10_FLOAT formats In real-life (TM) I always have to store texture data in DXT compressed formats ... if I want to opt for a better color quality in compressed formats, nothing seems to have changed between DX9 and DX10 ... is that correct Thanks in advance, - Wolf Hi, it is actually www.coretechniques.info not com ... :-).

• Visual Basic Is VB a good choice for grabbing data from excel and putting them in a java app?

  I want to automate what I do with my fingers. Namely, grab fields in excel and paste them in a goofy IBM program and then scroll, etc. I tried AIM-KEYS macro language which works good, but it doesnt let me resize windows, jump to different windows easily. (I have to organize them along the bottom of my desktop before I kick off macros). Anyway, thanks for reading. (This is prehaps a non-VB question... ) -jim isdn128@bellsouth.net (my registered email is no longer valid...ugh) You have acouple of choices with VB...VBA from within Excel or a VB.NET application...the trick to being succesful in this is the 3rd party (IBM) program that you reference....Does it have an API and/or Is it ODBC compliant ...Show All

• SQL Server Trying subreports - does not work

  Hello colleagues, I have the following issue: I am trying to create a report with subreport this way: 1) create report 2) create subreport. Set parameter @AccountName in the SQL query (...WHERE account.name = @AccountName) and in the parameters collection - AccountName, data type string 3) place the subreport into the report and set parameters AcountID = =Fields!name.Value, so that the WHERE clause in the subreport should filter the content according to the field Fields!name.Value. So far, I suppose this should work. Nevertheless, I get this result in Visual Studio .net: An error occurred while executing the subreport ‘subreppp’: An error has occurred during report processing. Cannot read the next data row for the d ...Show All

• SQL Server Variable Value: How do I set it from value in flat file at runtime

  I have a number of DTS packages I am trying to convert and am totally new to Integration Services. I have a flat file that I reference to get a date that I use in some SQL statements in the package. It seems like the best way to do this would be to create a variable to hold the date and set it at run time from the flat file. I've been searching the documentation and the forum and can't figure out how to do this. This is so basic that I feel like an idiot putting it on the forum but I need some help. This whole Integration Services thing is a big shift from DTS (which I eventually became pretty good at) Now I'm back to ground zero. Any help would be appreciated. If you can direct me to any basic training resources that would be cool t ...Show All

• Visual Studio 2008 (Pre-release) Dummy question: Certificates & Services

  Hi, I'm quite new on using WCF and coming from a .Net Remoting world. I found a lot of common design practices that makes it quite easy to understand. However, I have some issues with the security side. It seems that if I want to use security with my services, I need to "sign" them using certificates. This is fine if you are in a standard client-server application that is gathering and pushing data from/to a server. But in my case, I want to use services even on the client side which would therefore mean that I need to deploy certificates also on the client side which may bring some issues as far as I understood. I still didn't decided on using either Peer-to-peer communication services or TCP services but whatever I ...Show All

• SQL Server Column Name as Variable

  Greetings, I have a table that contains various columns in it totalling 12,000 rows of data. For example; site_ref, account_title, gl_code, period1, period2, period3 etc through to period12 I wish to write a query that will allow me to search for specific site_ref, acount_title etc and then only one of the period columns. This period column will be specified by the user at the time of submitting the query through reporting services. How do I assign a column to a variable so that the user can set it in the report parameters and then the code will run against that specific column for the period Example would be to see everything for site_ref = 'tb', account_title = 'gross rent' and the financial figures within the column title ...Show All
