• Visual Studio Express Editions A Puzzle?

  Below is the code, and you can press Button1 as fast and as often as you like to get a list of 6 random number from 1 -7 but if you change this intNumber = Int((7 * Rnd()) + 1) to this intNumber = Int((6 * Rnd()) + 1) it still works by giving a list of 6 random number from 1 -6 but it only does it once Public Class Form1 Dim intNumber As Integer Dim arrNumber(0 To 5) As Integer Dim i, x, y As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click ListBox1.Items.Clear() For x = 0 To 5 Start: Randomize() intNumber = Int((7 * Rnd()) + 1) For y = 0 To 5 If intNumber = arrNumber(y) Then G ...Show All

• Software Development for Windows Vista User Interface to change rules

  Hi, I am just trying to compare Windows workflow rules engine with a typical Business rules engine. In WF, we can make Rulesets and it provides fantastic features like Forward chaining,etc but was wondering if I want to change any rule in the Ruleset I need to change the code and build my application again. And this activity has to be done by some developer only. Does WF provides any User Interface for Business Analyst kind of people to manage these rules/rulesets Regards, Ekta Ekta, Currently, the WF designer is focused on the developer audience. A custom UI can be built on top of our API, and we anticipate that partners (and end users) will build designers on top of our model, targeted a ...Show All

• Visual C++ Can't optimize my project

  I want to optimize my project's size, so I selected the Minimize size (/01) option, but I can't compile it: cl : Command line error D8016 : '/O1' and '/RTC1' command-line options are incompatible What can I do The /RTC1 compiler option means "Enable run-time error check features". It seems that this option cannot be specified together with "Minimize size". Therefore you have to disable it. It can be found at Project Properties --> C/C++ --> Code Generation --> Basic Runtime Check . Change this value to "Default". I hope it helps. It seems that you are trying to optimize your program based on "Debug" compiler configuration. In my opinion it is better first to ...Show All

• Visual C++ C2666 error - does this violate the C++ standard ?

  Consider the following example below that generates the C2666 error. I believe this violates the C++ standard section 13.3.3.2 paragraph 3.

  Hi, I need to enumerate all the available classes which are derived from DataSet with VSPackages (not using DTE). Is there anyway to get a reference to one of the enumerated class Thanks in advance, Denniz AFAIK, you need to use DTE.

• Visual Studio Multiple projects or multiple database???

  We have many different applications. Should I create separate sourcesafe databases for each application or should I create one database with multiple projects The advantages of the latter are obvious in that all code can be seen at once. Our company uses contractors on a regular basis however and it would be nice to only give them access to the application they are working on. What are people's thoughts on this Thanks. Hi Yes, you highlighted two of the main concerns. Ease access by have a central database and security in limiting access to contractors. You should try to keep the database under 5 gig in size so if combining applications into one database will make your database start to app ...Show All

• SQL Server Visual Studio C++ and SQL Express

  I currently have Visual Studio .NET 2003 installed on my computer and I am trying to develop an application that would require the use of SQL data base on a network using C++. Would I just need to install the SQL Express and Express Manager to get Visual Studio working with the database Or do I need to also install Visual Studio C++ 2005 express to get the data base features working correctly. Thanks Installing Express is technically all you need, I do recomend Management Studio Express as well to make life easier. The features for data in VS2005 are much richer than in VS2003 however VS2003 should work just fine. ...Show All

• Community Chat Using Vista?

  Good idea Joe! Okay, I'll go first.  I'm using Vista RC1 full time now.  The computer seems quieter--doesn't take so many trips to the hard disk for VM paging.  I find going back to XP an unpleasantry, so I think Microsoft is succeeding here. Glass is nice.  I think the performance is what I expected it to be on an Intel Advanced Graphics card (Dell Dimension 9100).  Office 2007 is also pleasant to use, but they stil have some cleanup work to do on their UI. Who else is using Vista   Brian I have the same exact computer. The only difference is that I'm on a raid 0 array that is not partitioned, and I have a nvida 6800.
