• SQL Server About Login Account

  Hi everyone, I have a simple question for you which is too important for me. My question is about logins in my own(local) server. I know that my local server(my computer's server) has to default login account which are called sa and BUILTIN/ADMINISTRATOR. While I am using my own server, I do not know which default login account is used by my Server since I use windows authentication while connecting to the Server. Another question is that while adding new login account for my own Server, I noticed that there is a choice which is comprised of Grant and Deny for the Security. What is the meaning and usage of this Thanks and Regards I s ...Show All

• Visual FoxPro editbox programmatic change

  I am looking for an easy way to determine if I've made interactive change in an editor box. The issue is that there are about 16 controls on a container, they are initialized from a table record thus their values at activate time generally are not trivial default. I have to save the changes with a SAVE button if I made any but I want this button's click method to quickly determine which control values have been changed. I do not want to do REPLACE for the fields with values that haven't been changed. In case of simple controls like a combobox I can store the initial value in Tag property and do the comparison programmatically. Sometimes t ...Show All

• Visual FoxPro deployment, building exe problem

  OK, this is the third round. I still cannot run an exec file. I cannot build it properly. When I issue (in the Command Window) BUILD EXE the intellisense prompt appears with my app name. So, I accept the rest of the clause as default. Until today I could generate .exe with no problem but had problem getting it started. Today finally for reason I cannot explain an error appeared during BUILD: Unable to find Unknown ARR . Just as simple as that. No further explanations forthcoming. There are three choices aside from " Cancel :" " Locate ," " Ignore " and " Ignore All ." If I cli ...Show All

• Visual Studio Debugger doesn't like the backgroundworker anymore?

  I seems like it's not possible to interrupt a multi-threaded application using Backgroundworkers in another thread than the main one. Everytime I set a break point into another thread than the main one, the application stops at that point, but then, going step by step is not possible anymore and the application runs in an unstable state and I don't have any other issue than re-launch it. This leads to the annoying situation where I cannot debug that part of the code. It used to  work fine with beta 2. Anybody noticed that Or is it just me Hi Gregg, I've tried all your methods, but it still doesn't w ...Show All

• Visual Studio 2008 (Pre-release) ListView performance when resizing columns.

  Hi, I'm using the ListView control with a standard GridView. I have about 8 columns bound to a DataSource (which inherits from Collection<T>) using aDisplayMemberBinding for each column. I don't give a CellTemplate - I just let the GridView display the values as Text. My problem is with Performance. I have about 250 items in the Grid (I'm going to need up to about 600), and yet already the performance is not good: specifically with resizing the columns. Clicking a column border and then dragging takes about a second to respond. Is this a known issues Is there something I can do about it Thanks, Sam ...Show All

• .NET Development Network configuration problems

  I am setting up a W2k3 server with dual nics and am having trouble getting it to work properly. Here is my desired configuration. ( my goal is to do it good enough without going overboard on the cost ) Internet -->hardware router ---> W2K3 server ----> switch ------> 5 other computers The main reason why I wanted a hardware router was to provide one more layer of protection from the internet. I plan to use a DLink DI-604. It is set up to provide a static IP address to the W2K3 server. The server has two nic cards in it. One is connected to the router and the other is connected to the switch. I used the default first ser ...Show All

• Software Development for Windows Vista Visual Studio 6.0 SP5 setup on Vista Beta 2 (5384)?

  Does anyone know how to get around the MDAC check in the Service Pack 5 setup of Visual Studio 6.0 For some reason it doesn't detect MDAC 2.5 or higher which it requires (even though Vista obviously has a later version - 6.0) and the setup will not continue from that point. I've tried every registry key I could think of to trick it into thinking MDAC is installed. Thanks Ted. Totally untrue - the support on Vista has been committed to by Microsoft until March of 2008  http://msdn2.microsoft.com/en-us/vbrun/ms788708.aspx I know for a fact that it runs perfectly on Vista as I have run i ...Show All

• Visual Studio 2008 (Pre-release) DLINQ Queries and observations

  I have the following queries/Observations about DLINQ. 1. I could not find any direct way of handling many to many relations. Suppose if User and Role are related by a join table UserRole then I should be able to have a collection of Roles in User and vice versa. Which i think is not possible in DLINQ. (Please correct me if I am wrong) 2. State management is handle outside entities. In scenareos where a client grabs a entity from a WS , makes some changes and post it back to the ws for updation, how is the DLINQ framework handle optimistic locking Why can't state be maintained in the entity itself maybe by a base class, we already c ...Show All
