• Visual FoxPro how to shutdown the OS without error

  good day to all. i use my Net monitoring system developed in VFP at my net cafe for almost a year now, and so far it works fine. But there is a little problem that although it don't bothered the user and me but it much better if it does not shows-up. When i shutdown the workstation or restart it from the server, before it will totally close there is sometimes that a VFP error message will pops-up, which will prompt to send the error to MS. How could i prevent such error as if there is still missing in my shutdown code, clear events, clear dll's, etc and etc they've all there already. it seems that the PC can't wait any longer to shutdown. Thanks for any help regarding this matter Madix_t wrote: When i shutdown the workst ...Show All

• Visual C# I have a really newbie question on scope

  Under C I would do something like “const int Max = 25”, And place this in a header file which I #include in all the C files, so the whole application had scope to Max. I know I have to use static and C# doesn't have include files, so where do I put it so the whole application h as scope to it (Max=25), without physically coding it in every file You could also use static classes, so you dont have to instantiate a class every time you need to get static, constant values. //using C# 2.0 public static class Constants {      public const int MAX = 25;      public const int MIN = 0;      public static double _2pi;   &n ...Show All

• SQL Server Derived Column Logic to replace empty string with null?

  Ok.. so I have a fixed position data feed. I read the file in as just whole rows initially, process a specific position and evaluate a conditional split to determine direction of the file for proper processing (file contains multiple recors with different layouts). This all works fine. I then use the derived column feature to process all the columns. Most of the columns are as simple as SUBSTRING(RecordData,1,10) for example to get the first column. This all works for string data. I then have a column that is a date field. The problem occurs that the code SUBSTRING(RecordData,20,10) returns either a date or empty set of data if no date was in the original file. When this gets sent to the OLEDB connection (SQL Server 2005) into the date ...Show All

• .NET Development VS2005 - Create SQL Indexes in dataset

  I'm currently filling several datatables in a dataset using sqldataadapters. I can pull the data and schema from the tables using da.Fill and da.FillSchema, but is there a way to pull the indexes (other than PK) from the SQL database into the dataset as well Thanks. No, database indexes are not supported in a DataSets. DataSets will create their own internal indexes, depending on reletions and what kind of DataViews were created based on data in a DataTables ...Show All

• Visual Basic Process not completing

  I have a vb form that runs a command line executable that creates a diff file from two existing files. When I run the program from the command line it creates a 419Mb diff file. When I run it as a process from my VB program it gets to ~400 Mb and stops. If I kill the VB program the command line executable continues to run and finishes the diff file. So I have 2 questions. Why does the process stop before for it finishes when I run it inside vb Why does the program continue to run when I kill the VB app. Here is my code Private Sub xdelta( ByVal strFile1, ByVal strFile2, ByVal strDelta) Dim strError As String Dim p As New Process Dim info As New ProcessStartInfo info.UseShellExecute = False ...Show All

• Visual Studio Tools for Office VSTO Runtime Installation

  I noticed the below in the MSDN documentation concerning the VSTO runtime installation. "How to: Install the Visual Studio Tools for Office Runtime - You do not need to install Microsoft Office applications on computers that you install the Visual Studio Tools for Office runtime on. For example, you can install the runtime on a server and use the ServerDocument object to access document files. If you do need Office applications on the computer, install them before you install the runtime. If you install Office after installing the runtime, you must run VSTOR.exe again and repair the installation." This seems like a hassle, since the end-user will install my app and I have no control over whether they install it before and/or afte ...Show All

• Visual Basic Backgroundworker Fundamentals

  Are these background workers slow or what If you give it a simple 2-3 lines of codes, it could take a long time for it to execute. No, that's not true. The background worker will execut the code but it appears to have amensia, because the error - thread cannot run multiple tasks at the same time... which means, even though it has finished running the code, it cannot automatically dispose itself and therefore is still active until some element deactivate it. Oh, I can understand on a single core CPU, it might have to "wait" until it turn is up - but come on, on a dual core... what's the wait I don't suppose if you tell ******** to give more processing power to background services would help ...Show All

• Visual C# How can I Instantiate a dynamic array and still be dynamic after?

  Hello, I have a program which pulls config information in from a file. The files length will vary depending on how many items are configured in the application. the application stores the config information in an array while reading the file. since the file's length varies the array must be dynamic after instantiated. From all the information I have found I know I can prep a dynamic array but I cannot find any info on instantiating it dynamically. All the info shows is instantanting the dynamic array to a static one. anyone have information on keeping the array dynamic Either that or is there a way to determine how many lines in the file are left from the current Stream position It would have to be in lines, not characters.

  Hi I am trying to create a statefull booking service (state machine workflow exposed as webservice). It has the following states. Created, TicketSelected, Pay, Comfirmed. My question is twofold.
