• Visual Studio Sharing common files between projects

  I have a number of projects which share common files so I put a single copy of these into a "Common" folder on my workstation. This folder is at the same level as my projects i.e. C:\Projects\Common C:\Projects\ProjectB C:\Projects\ProjectA etc So in folder C:\Projects\Common I have Shared.h. Within both Visual Studio 6 projects A and B I have various project specific files which "persist" as e.g. C:\Projects\ProjectA\MainFrame.CPP, C:\Projects\ProjectB\MainFrame.CPP and in both projects I have Shared.h which "persists" as ..\Common\Shared.h. Obviously if I modify Shared.h the changes propogate correctly to both projects. So far so good. Now I add a similar project structure into my Visual So ...Show All

• Visual C# how the overriding mechanism happening?

  Hi all, I would like to know that how the overriding mechanizm happening . I know the concept but while compiling i would like to know that what is the mechanizm used behind that . thanks Gomaz Let's say we have 2 classes A and B: class A { public virtual void Func() {} } class B : A { public override void Func() {} } Each instance of class A and B will have a hidden pointer to an array of pointers to functions called Virtual Function Table (usually acronymed as VTBL). Since in our example we only have one virtual function the array will only have one entry and this is the pointer to Func. When an instance of class A is created, its VTBL will be initialized with the address of function ...Show All

• SQL Server Stored procedure run from ASP.NET page gets very slow intermittently

  I have developed a stored procedure that filters a view that is a union of several different tables. This provides status information for items across our warehouse management system. This system seems to work very well and normally processes results very quickly (< 3 seconds). However, occasionally (every few days) we begin to see timeouts on the query after 3 minutes of processing. I can watch this process in SQL Profiler and see that the query is timing out after 180 seconds, which is the timeout we have for the query within the DAL. When I copy the line from the SQL Profiler and execute it directly in SSMS, the query executes in less than 2 seconds. I first thought that somehow this had to do with execution plans, but when I try ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Where in content pipeline does volume textures fail?

  Currently volume textures aren't supported in the Content Pipeline. So if I have a mesh that references a volume texture it will fail compiling. So, is it just a matter of writing a custom importer for volume dds files or is it all the way through the pipeline Will ContentManager.Load<Texture3d>(...) work if I just write the importer Say it is so...it is Christmas after all :-) Sorry I think you'll find that the content pipeline is easier to extend than you might think, though. Have you checked the help There's a good walkthrough in there. Once you've written it, though, it will work with ContentManager.Load<Model>, don't worry about that. ...Show All

• Windows Forms MDI children's child

  I am opening a form from a MDI child form. MDI Form --> Child A Form --> Child B Form. Child B is opened from Child A. However they should both be children of the MDI form. How can I make this new form a child of the top level MDI form Thanks thanks - but is there a way to have the form be modal and confined to the borders of the MDI form. f3.ShowModal(this.MDIForm); that allows the form to leave the frame of the MDI form. Is it possible to have both ...Show All

• SQL Server Migrating a db from SSE 2005 December CTP to SSE 2005 Release Version

  I have a developer who built an application using the SSE 2005 December CTP and I would like to bring the db's into the official SSE 2005 released version. I have attempted the following: 1. Create the db's in the released version, detach and re-attach the CTP db's. I got an error telling me they were incompatible. 2. Installed CTP version on one server, backed up the db's and then attempted to restore the db's on another server running the official released version of SSE 2005. Got an error attempting that too. 3. Installed the Management Studio for SS 2005 Developer edition thinking that I could connect to the two seperate instances of each server and like I could in EM 2000 run the transfer wizard to move the db's and data from ...Show All

• Visual Studio Team System PendDelete usage and differences between item and extendedItem

  Hi all, I have used the following code to delete some files and some folders from my workspace. _W.PendDelete(PhisicalPath); PendingChange [] pc = _W.GetPendingChanges(PhisicalPath); _W.CheckIn(pc, “...” ); Where _W is the workspace. For the folders everything worked perfectly. For the files what happened is that in the Team Explorer the files are still there. Now if I do VersionControlServer.GetItems(ei.SourceServerItem, RecursionType .None); I don’t get anything. Instead if I enumerate the ExtendedItems the files are there. I have two questions: First of all what is happening What is the difference between an item and an extendedItem Second: How would I delete t ...Show All

• .NET Development Getting Version

  How can I get application version at runtime (or compile time) I want to show the version (which is set in assembly attribute) in about Window. I tried this Policy::ApplicationSecurityInfo ^asi = gcnew Policy::ApplicationSecurityInfo(AppDomain::CurrentDomain->ActivationContext); versionLabel->Text += asi->ApplicationId->Version ; That makes the program crashing. An unhandled exception of type 'System.ArgumentNullException' occurred in mscorlib.dll Additional information: Value cannot be null. So what should I do Thanks. It returns the file version, sure you don't want that If you want the assembly version, use the Assembly.GetName().Version property. For example: using System.R ...Show All

• SQL Server promotional mailing response prediction

  I am trying to use the time series algorithm to predict responses to promotion mailings for subscription renewals. The problem i am having is that response is largely influenced by the number of mailings that are sent out. Can anyone give me any ideas on how i can structure the dataset so that it would take into account how many promotions were sent out any help would be greatly appreciated. Frank My guess is that you really don't want to use the time series algorithm here. You can create a dataset that uses previous response rates, calendar information and the amount of promotions mailed to predict how many responses you are going to get. For example, creating columns such as PromotionID DayOfW ...Show All

  Hello, I need to submit my software for the Works With Vista logo certification. However, I'm asked to sign some sort of a legal PDF form (which is fine by me).

• Visual Studio debugger will not step through code, only metadata

  HI. When I try and step through my code (an app that contains 8 diff projects), and call a function in a referenced dll, sometimes it steps right into the dll, and sometimes it steps into a "[from metadata]" file...Of course, the metadata file does not provide the actual functions/routines, only stubs... what the heck is going on When this happens, VS 2005 gets mysteriously slow at the same time...for instance, when I click F9 to add a breakpoint, it takes five seconds for that to happen. very frustrating! any ideas thanks, Steve Sounds like the source code no longer matches the debugging information. Try rebuilding your projects... ...Show All

• Visual Studio Express Editions User Control

  The small project that I've been working on is now finished and I'm rather pleased with it. Thanks to the help on this forum it works just as I wanted it to, so much so that I thought it I would have it as a control so that I can use it in future projects. Looking back at a my previous post on how to create a user control I got stuck in and up to this point all well, however, I have hit a couple of sticking points, quite a bit of the code that I pasted in to the user control had squiggles which, after following the error correction tips I've sorted but there are two where no tip is available and these are the two that I am asking for help with. 1) Label1.BackColor = Color .FromKnownColor(cmbSelected.SelectedIndex + 28) Name 'Color' is not ...Show All
