• Software Development for Windows Vista Is there a "standard place" to store writeable not plublic shared files to please UAC?

  Our program has two files must be writeable (a database file and a config file) which are shared by all dedicated users of the program on a single system. The automatic redirection to a single users directory path is not helpfull in that case. Before changing our program: Is there a standard place on Vista to store writeable not public shared files (We whant also to pass Vista Logo test...) Thanks in advance Hi Lela, sorry, i did not got an answer nor found a acceptable solution on our own... It seems to me we are doing the very old "Main fault of IT: Dividing function and data" again - but only on a higher level now. To stay solution oriented: Where would you place a Jet database file and a config file ...Show All

• Visual Basic XML or a database?

  I'm creating a program that basically parses textfiles and stores them into a database for easier manipulation (so I can run queries on a DB instead of parsing/comparing/etc raw text on-the-fly) Currently I am using an Access database to store everything, but now that I realize .NET has such great XML support, I figure this may be a better option.  I'm thinking of storing each file into its own XML file then loading the selected file into a dataset and pulling info from it.  This is basically what I'm doing now, but instead of XML, it's the Access db. Does anyone have any advice on which method is better  EDIT: Wow, I forgot to mention something important.  What I wanted to know is, how do I han ...Show All

• Smart Device Development Questions on using RIL on Smartphones

  Hello, I am new to developing on the Windows Mobile platform and have just started writing an app for Smartphones running Windows Mobile 5.0. My first task is to get the cell tower ID that the phone is currently registered to. I searched MSDN and other discussion forums and found that I can use the RIL functions to get this information. My first confusion was wether RIL was even supported on Windows Mobile 5.0 since MSDN includes RIL and Cellcore under 'Windows CE Embedded 6.0'. However, judging by some messages on other forums, RIL does seem to be available on Mobile 5.0. So far, so good. I tried to write a simple app using RIL functions but couldn't build it. I can't find any RIL-related files in my SDK install. After some more searchi ...Show All

• .NET Development Error with WebRequest

  Hi, I am using the WebRequest object in vb.net to post data to a webserver. I am also using a java application to post the same data to the same webserver. If I post the data using the Java code, it gets a response code of 400 and and a descriptive error message. However if I try using the vb.net code, the code generates an exception once you try to retreive the response headers. What I want to do is get the 400 response code along with the associated error that is generated by the webserver. Seeking Help....

• Visual Studio Express Editions ListView line number

• SQL Server T-SQL Question

  I need to figure out how to write a stored procedure to get the correct daily AAbutter price for sales orders on a particular day. I am pretty confused...but I am just a beginner. First of all, a sales person will input a date (@Date) to obtain a correct daily butter price for that day. This will be the date that the order was received...so it doesn't always mean that it is the current date. They will also put in a customer number as well (@Cust_Num). We have a table that gives historical data for the daily AAButter price with the fields MktDate, Price. The catch is how we deligate the AAButter price to our customers. They are categorized in 3 ways: Daily Pricing, M-F Average, and Thursday-Wednesday Average (with no SATor Sun AAButterPr ...Show All

• Visual Basic conversion from c# to vb.net

  public class FloatToolStrip : ToolStrip { private Form floatForm ; public Form FloatForm { get { return floatForm; } } c# is case sensitive so floatForm and FloatForm are different. vb.net is case insensitive so when the inline compiler sees FloatForm, it says it has already been declared. how do I convert the blue code into vb.net Thank you. -greg As you've seen, the case insensitivity of VB.NET will not like your code when directly converted... instead a common option is to prefix private variables with an '_' or 'm_' like so: Public Class FloatToolStrip Inherits ToolStrip ' Private m_floatForm As Form Public ReadOnly Property FloatForm() As Form Get ...Show All

• SQL Server Report Builder - Numeric Aggregate Aggravation

  So I'm building a report model containing several 8 or so numeric amounts.  All amounts are numeric(10,2), and there is nothing that would differentiate the columns other than their names. One of the columns WILL NOT generate any aggregates.  It just appears as an attribute.  It's inexplicable.  I've even tried to build a model containing just this one numeric attribute, and it still does not work!!  VS just hates this one element!  Anyone seen anything like this   I'm running VS 2005 Sp1. WHAAAAAAAAAAAAAAATTTTTT     What genius came up with that!  Any why would an ID field be numeric 10,2!!   Thank you thank you ...Show All

• .NET Development .NET 1.1 Process class - peculiar/problematic behavior

  Hi, I am executing a console application using Process class using .NET 1.1 with SP1.   It has been working fine until we encountered a particular Windows XP SP2 machine - let's call it machine X.   On this machine, the newly spawn process simply returns with return code -1 (i.e., it's an error), and it does not generate any output to standard error or standard output - most likely it couldn't even have gotten started properly. The console application being spawn is a third-party application for which I do not have the source nor extensive documentation so I can't tell what exactly about this machine X that it doesn't like.  Without the source, attaching a debugger and stepping through is not an opt ...Show All

• Windows Forms classic combobox problem

  If you are binding a combobox to a datasource how can you add the infamous "select one" as the first visible selection. I have done this for webforms using the 'listitem" but it seems that this need has been overlooked for windows forms.
