• .NET Development Failed to initialize huge arrays

  I have to initialize a huge constant array of structures(60000~100000), used as a lookup table , but it failed with System.InvalidProgramException when the items reach 18400. and if I change the item type from struct to class, the threshold is 35000 . It seems that there a size limition  when initialize constant in CLR. Is there any configurable parameters can be used to increase this limition in C# compiler or .NET framework. Or I'm missing something there   using System; struct st {   public  short t1,t2 ;   public st(short t1,short t2){     this.sym = t1;     this.act = t2;   ...Show All

• Software Development for Windows Vista Windows Worflow Designer

  Where can I get documentation and examples of using the cancelActivity (located on the second tab of the workflow designer - on the bottom).

• Windows Forms Proper splash screen design

  Hello everybody, I want to ask what is the best practice for splash screen design. Should the main method start two separate threads for the main form and splash form Or some other approach Like the main form spawning the splash thread Because I'm rather confused, I've been reading quite a few articles on splash screens all use different approaches and entry points. So I just wanted to ask what's the best practice about the problem. Any advice is greatly appreciated. Regards I think I've found the solution to the .NET startup delay problem. There is a Win32 component that loads up your splash screen J ...Show All

• Visual C# User Selected Database Path

  I am currently creating a frontend for a database. The frontend is essentially used to input data into the database. However, since the database needs/is stored on a server, my application will not find it, as the app.config file specifies the connection string as "C:\...\filename.mdb" which is the path of the file on the computer I am creating it on, not of the server.   Is there some way to modify this code to be set by the user, from some kind of config form Perhaps using a openFileDialog and setting the selected path as a local variable and defining the connection string as this path If this is correct, how would I code t ...Show All

• SQL Server Problem with DTS Source using Pervasive SQL 2000 (Btrieve) ODBC driver

  I am trying to use a DTS package to extract data from an old Pervasive SQL 2000 (Btrieve) data source, and copy into an MS SQL Server table. I have installed the Pervasive ODBC driver and got linked tables in Access working.  I can see the data. When I create the DTS package, it shows a list of the tables in the drop-down, but when I hit the Preview button I get an unspecified error.  I can finish setting up the DTS package, the new MS SQL Sever table gets created, and the field transformations all look correct.  However, when I execute the package it fails.  In the logs, I get an unspecified error, the only error c ...Show All

• Smart Device Development .NET CF 2.0 Picturebox

  I'm currently developing a graphics Pocket PC 2003 application using MS Visual Studio.NET 2005 to overlay an EMF image on top of a bitmap.  I know that metafiles are not supported in .NET CF 1.0 and the Picturebox control gives an 'ArgumentException' when you try to display it.  Are they supported in .NET CF 2.0   I'm curious because when I run the executable from the 'Release' folder in the application directory on the Windows XP desktop, it displays the bitmap and the EMF, but gives the following error when I run it on a Pocket PC 2003 device (HP iPaQ):  An error message cannot be displayed because a ...Show All

• Windows Forms Binding Comboboxes to custom lists

  I am running .NET Framework 2.0 B2 I am missing something when it comes to implementing databinding in custom classes. I have a view class that acts as my main data source. The view class basically just loads up the data and returns via properties and BindingLists of NameValuePairs (which is just a replacement for KeyValuePair so that databinding will work) The view class also maintains current properties that tell me what the current selected id is for my state, city and street. However when I run the form the databinding seems to get behind. If I choose a new state, the cities refresh, but the text in the state box stays the same. Then whe ...Show All
