• Smart Device Development SQL mobile 2005

  Hi There, I'm currently writing an application for a windows mobile 5 device which will store data in sql mobile 2005. I would like to know which would be the most efficient way of writing the following example to work with the above. (up until now all the code i have written has been in vb6 and connecting to an access database) Set db = DBEngine.OpenDatabase("location\database.mdb") ' strSQL = "SELECT * FROM Floats WHERE AgentName = '" & lblAgentName.Caption & "' AND Status = 0 " ' Set rs3 = db.OpenRecordset(strSQL) If rs3.RecordCount > 0 Then rs3.MoveLast lngRecordCount3 = rs3.RecordCount rs3.MoveFirst Else lngRecordCount3 = 0 End If ' If lngRecordCoun ...Show All

• .NET Development .NET encourages poor coding?

  The more I look at .NET error handling, and how to deal with it, the more frustrating it gets. Take this class for example.   It has a single boolean property.   You have to know on which side of the call an error will be raised… by the caller or the callee… well here’s a prime example.    Say you have to read data from somewhere like a text file and you cannot ensure the format of the data is proper.   Well, you cannot depend on a property to check that data for you if you strongly type the property. Read the orange comment to see what I mean, and please let me know how you deal with this situation since to me it appears to require horrible program design.     Public Class ...Show All

• Visual Basic PrintPreview awkward to use?

  It might be just me, but doesn't PrintPreview work rather backwards I'm used to constructing a report from the top down: Whenever the line count goes over say 60, I do a formfeed which prints the page, set the line count back to 0, and carry on like that. That seems very natural. But with PrintPreview, I must have a single routine for handling the printing of any page. What if I don't know what will be on page 6 until I've printed pages 1 to 5, which happens often What might be on page 6 with one report run might be a different page with another run, depending on the content. What if pages may have various different formats I can't do a 'switch' on the page number because I may not know on which physical page some parts of ...Show All

• .NET Development Get list of tables in ACCESS using VB.Net app

  I am using Visual Studio 2005 (VB.NET). My app. is using an Access db in the background. Once connected to the DB, I want to display a list of all the tables in a combobox on one of the forms. How do I go about doing this Thanks Nihal, thanks your code seems to be working well, except for the error message below: "More restrictions were provided than the requested schema ('Tables') supports." If I take the restrictions out, the code works, but all tables are displayed, which I don't want. Any idea how I would fix it ...Show All

• Visual Studio Team System Validation Rule: Find Text - Regular Expression

  I need to verify that a transaction id and confirmation id were actually returned. Both values appear on the page but I do not know what the exact values will be. The transaction id should be six digits long and the confirmation id should be 16 characters long (0-9,A-Z,a-z). The challenge is that I am trying to use a web test and I want to avoid writing code if at all possible. The Find Text Validation Rule has an option to set "Use Regular Expression" to True, but I am having trouble finding examples using this. Can anyone give me examples of how to use Find Text to search for transaction id = 123456 or confirmation id = 12345abcd67ef89gh when the exact ids are not known Thanks in advance... ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Intermittent Audio Problem

  Hi, I've been developping a game recently and I'm having major trouble sith sound. I am pretty much using the code from the XNA Framework audio sample. So I can't imagine what's wrong with that code. The problem is that I'm getting intermittent clips being played. Some don't even play at all when I call the Sound.Play method, some play but stop before the end on the clip, sometimes they play fully. This does not happen rarely, I'd say this is about 50% of the time and more often on longer clips. The only one sound I've got that seems to play correctly is a clip that I am looping (alarm sound), which is of lower quality 8KHz vs 44.1KHz for the other ones. So that's basically it, I'm using XACT V2.0. I tried following the instructions ...Show All

• Visual Studio Team System R

  Maybe a Bug in Visual Studio 2005 SP 1 !!! I'm able to reproduce on different machines with Windows XP and Vista with (Vista Update for VS SP1) Problem: 1. Start Solution and run Tests - works fine as desired. 2. Rerun Tests - VS freezes and processorload becomes 50% Additional Information: We have a Solution with ~ 95 Projects and the tests are grouped together in ordered tests. Is someone out there who has similar problems or can help Greets, Helmut Hi David, Thank you for your reply. Unfortunately I can't even reproduce the problem on my home computer (identical software config as the one at work). Unlike the freeze problems reported by Jeff, mine are predictable and occur only when I execute a b ...Show All

• SQL Server Should SQL 2005 be a dedicated server without other apps installed?

  I'm planning an SQL 2005 deployment and would like to know if an SQL server should be kept as dedicated as possible. Should apps that access SQL be kept on other servers What are the do's and don't's along these lines The plan here is to install everything that accesses SQL on the same server with the database, but this seems like a bad move to me. Am I right Thanks! Gregg SQL Server should always have a predictable level of system resources. Response from hard drives, memory, processor speed, bus speed, etc should always be the same. Otherwise, your compiled query plans are useless. So no additional apps, no funky compression engines, no diskkeeper, no disk replication, no shared SAN luns. You can, h ...Show All

• .NET Development problems importing data from XML

  Hello, Sorry not having written a more detail Subject for this topic, but i dont know how to explain it in so few words! I'm developing a pocket pc application, which is using a database also used on the desktop computer, and both apps exchange data using export and import functionalities.

Taking a quick look at xml file i'm trying to read, i can only see one cause for this problem: Instead of specifying the various elements like <table> <row1> <atr1> <atr2> <row2> etc.... its is ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Spacewar slow build

  I just tried to build the Spacewar starter kit and it took quite some time to build (5-10min). It spent most of its time building the content. Now, I could perfectly understand the slow build time since there's a lot of content to process (50MB output), but what bugs me, is that my computer becomes nearly unusable during the build. It takes about half a minute to alt-tab from C# to an explorer window while the build is busy. The thing is, I have a dual core processor (which was only at 50% during build) and neither the HDD nor the RAM were actually stressed during the build, so I would expect it to be responsive. For example, when I use the windows calculator to calculate 80000!, the taskmanager shows the same situation as when build ...Show All
