• .NET Development executing a .exe on the client?

  Hi, I'm builing a web application using web services. I want to execute a .exe on the client. How can this be done Right now I'm doing it with ActiveX, but I need the application to work when AxtiveX is disabled in IE. The application will be running on a LAN, not Internet. Thanks!     Hi, I don't think it is possible to do this since this would give a major security leak in IE. The best thing you can do is to make sure that your site is in the Trusted Sites Zone. This can be set up at the domain level so it works for everyone. In the Trusted Sites Zone, ActiveX applets are allowed by default. NOTE: All your clients need to have .NET installed in order to make the a ...Show All

• Visual Basic Automatic importing of text from txt file.

  I'm working on creating a new form for my company in Outlook. It's a simple helpdesk submission form. Each of the computers on the domain have a txt file located directly in the C: drive with the following information in it: Host name: Ip Address: (other information that doesn't matter). I would like to write up something in this form that would either automatically attach this txt file to the ticket as it's being e-mail out, or automatically pull the text out of this file and insert it into a spot on the form. I've been searching for 6 hours now and haven't been able to find what I'm looking for... Anyone know if this is possible Much thanks Jpeg To read the contents of a test file and place them in a textbox on a form. Somethi ...Show All

• Visual Studio Message for Empty Crystal Report

  In my Web application, I have Crystal Report that generates a report based on parameters selected by user. When a user enters parmeters which return no rows, I get report displaying report header, page header... etc. with no data. Instead of emtpy report, I would like to display a message saying e.g. "No records meet selection criteria". How can I accomplish this thanks Hi, I guess what melody is trying to suggest is that you manually query your database to see if there's a result. You can achieve this by using a Command and Datareader object. Just reply to this thread if you want a full sample. cheers, Paul June A. Domag ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game Levels like Quake?

  I found out from another website that there's an add-on (I think) for XNA Game Studio called XNA Magic that is supposed to load game levels made for games like Quake. Should I wait for XNA Magic or similar add-on before trying to create game levels Can I create game levels using XNA Game Studio only and a 3D modeler only Is it possible to create game levels that have two or more texture files I tried out DeleD Lite and found it too hard for me to use.

• SQL Server How to fit 16 hours of upgrade work into 2?

  How to fit 16 hours of upgrade work into 2 A client of mine is trying to upgrade their SQL Server box. They are on SQL 2000 now and the new box will be SQL 2000 as well. Before you ask, they don’t want to go to SQL 2005 for licensing issues (i.e. cost). The problem I’m having is that in addition to moving the database they need to add an update field (smalldatetime) with an index. Adding the new field and index to each table is taking around 16 hours on the new box. This client is an online retail shop and they are completely dependant on SQL being up. The have given me a 2-3 hour window to make the move. So how do I get the database moved and updated in 2-3 hours This is what I have done so far: Argue ...Show All

• SQL Server SQL comparison

  Hi there! can anyone help me out I need to compare a date from the database and the system date which will be coded in a store procedure in SQL... HELP!!!!! You may like to reconsider the answer given by Ali. DateTimes in NET are stored to a precision of 100 ns or 0.0000001 seconds whilst those stored by SQL Server in the SQL Server datatype DateTime are stored to the nearest 0.003333 seconds. Therefore you should not use a simple equality operator to compare them. Instead you should compare them based on the lowest precision argument, ie round the NET DateTime to the nearest 0.00333 seconds and then compare them. Regards, John Whattam. ...Show All

• Visual Basic ADO.NET book recommendations

  If it is not appropriate to ask about book recommendations on this forum, please let me know and I will withdraw the question. Can anybody recommend what I would consider a good book on VB8 and ADO.NET If it exists, such an animal would have the following qualifications: does NOT simply repeat what is already available from BOL, MSDN, etc., does explain how to programmatically use ADO.NET rather than just demonstrating how to use wizards, does explain when, where, why and how to use DataAdapters, DataSets, TableAdapters, DataTables, etc., does provide real world examples, does also include useful info I haven't noted here.
