• Performance problem Loading Dataset inside a virtual.

  - by ShaneH

  Host Configuration: HP EliteBook 8530w 4G Ram Win7 Ultimate 64Bit RC SQL Server 2005 64bit Developer Edition Virtual: Windows Virtual PC 1G Ram allocated Integration Services installed Windows XP 64bit Up to date service packs and .Net framework through 3.5 SP1 Sharing the Gigabit network adapter of the Host I have a simple .Net console application which loads a dataset of approximately 37K rows. Running the application on the host executes in approximately 4 seconds. Running inside the virtual takes 729 seconds. The size of the application grows to about 65Mb when the dataset is finished loading, no calculated columns or event handlers are attached. [edit] I changed the virtual to use a loopback adapter to communicate with the host and performance is now on par with running on hardware. Any ideas as to why it would going over the network adapter be almost 200x longer? TraceRt shows that the connection is only one hop. Thanks, Shane Holder

• Restoring Sharepoint content database

  - by jude

  Hi, My WSS_Content database had got corrupt. And my pc was infected by virus. I had no backup of my WSS_Content database. So, I copied the corrupt database to a separete disk, formatted and reinstalled Sharepoint, with SQL Server 2005 as before (I'm using sharepoint 2007 ). I used Sytools Sharepoint Recovery tool, that i found on the net, which helped me restore my corrupt WSS_Content database. Now i want to set this content database as my "The content database" for my newly installed sharepoint. I tried the steps that i found in the link :- http://www.stationcomputing.com/scblogspace/Lists/Posts/Post.aspx?ID=40 I get stuck at step 3. Can anybody help me. I am really in a big mess. Would appreciate any help. Thanks, Jude Aloysius

• Perl: calculating a delta of years from a date

  - by Spiros

  Hello, I am trying to figure out a way to calculate the year of birth for records when given the age to two decimals at a given date - in Perl. To illustrate this example consider these two records: date, age at date 25 Nov 2005, 74.23 21 Jan 2007, 75.38 What I want to do is get the year of birth based on those records - it should be, in theory, consistent. The problem is that when I try to derive it by calculating the difference between the year in the date field minus the age, I run into rounding errors making the results look wrong while they are in fact correct. I have tried using some "clever" combination of int() or sprintf() to round things up but to not avail. I have looked at Date::Calc but cant see something I can use. p.s. As many dates are pre-1970, I cannot not unfortunately use UNIX epoch for this.

• Viewing array of pointers to structures in Visual Studio in the debugger

  - by Fozi

  I'm having a problem displaying the contents of a pointer array with its contents in the debugger. If I just add the pointer to the watch only the fist entry is visible. But if I add the length to it the debugger assumes that I have something like array[length][length]. Picture The first entry is the broken one, looks the same with ,2 or with any ,2 x. The second one is what I would like to see, but for more entries. Edit: The two entries displayed as [x][1] are invalid. I'm using VS 2005 but I think I had this problem on 2008 as well. Is this a bug or am I doing something wrong?

• Scaffolding A model with an attribute of type datetime creates a 10 years range in the form

  - by b_ayan

  For a simple rails application ( 1.86 /2.3.5) , lets say I run a simple scaffold script/generate scaffold blog title:string content:text published:date When I open up the new / edit view for the blog controller in index/new.html.erb , I see that the drop down enabler for date select has a date range of 2005 - 2015 , i.e 5 years +/- I tried to change this default behavior by introducing this code f.date_select :entered, :start_year => 1970, :end_year => 2020 Apparently this has no impact to the behavior mentioned above. How do I increase the date_select range which seems to be default?

• Get the BindingSource position based on DataTable row

  - by Ronald

  I have a datatable that contains the rows of a database table. This table has a primary key formed by 2 columns. The components are assigned this way: datatable - bindingsource - datagridview. What I want is to search a specific row (based on the primary key) to select it on the grid. I cant use the bindingsource.Find method because you only can use one column. I have access to the datatable, so I do manually search on the datatable, but how can I get bindingsource row position based on the datatable row? Or there is another way to solve this? Im using Visual Studio 2005, VB.NET.

• Which has been the most reliable, fastest Windows C++ profiler that you have used?

  - by carleeto

  I need to profile a real time C++ app on Windows. Most of the available profilers are either terribly expensive, total overkill, or both. I don't need any .NET stuff. Since it is a real time app, I need the profiler to be as fast as possible. It would be excellent if it integrated in some way with Visual Studio 2005/2008, but that's not necessary. If this description reminds you of a profiler that you have used, I would really like to know about it. I am hoping to draw from people's use of C++ profilers on Windows to pinpoint one that will do the job. Thanks.

• snprintf and Visual Studio 2010

  - by Andrew

  I'm unfortunate enough to be stuck using VS 2010 for a project, and noticed the following code still doesn't build using the non-standards compliant compiler: #include <stdio.h> #include <stdlib.h> int main (void) { char buffer[512]; snprintf(buffer, sizeof(buffer), "SomeString"); return 0; } (fails compilation with the error: C3861: 'snprintf': identifier not found) I remember this being the case way back with VS 2005 and am shocked to see it still hasn't been fixed. Does any one know if Microsoft has any plans to move their standard C libraries into the year 2010?

• Visual Studio 2010 - Export (Project) Template menu option grayed out

  - by Jakobud

  In Visual Studio, I want to make a simple C++ project and export it out as a template, so I can use the template to start new projects to save me time. But the Export Template menu option is always grayed out. I've not once been able to click it. Anyone know why? Anyone know how to accomplish what I need (besides the obvious "make a copy of an existing project in explorer")? It seems like project templates should be a no-brainer feature for VS. This seems to be the case for Visual Studio 2005, 2010 (I probably 2008 as well I haven't checked).

• Output on namespaced xpath

• C++ - Opening a file inside a function using fopen

  - by Josh

  I am using Visual Studio 2005 (C++). I am passing a string into a function as a char array. I want to open the file passed in as a parameter and use it. I know my code works to an extent, because if I hardcode the filename as the first parameter it works perfectly. I do notice if I look at the value as a watch, the value includes the address aside the string literal. I have tried passing in the filename as a pointer, but it then complains about type conversion with __w64. As I said before it works fine with "filename.txt" in place of fileName. I am stumped. void read(char fileName[50],int destArray[MAX_R][MAX_C],int demSize[2]) { int rows=0; int cols=0; int row=0; int col=0; FILE * f = fopen(fileName,"r"); ...

• Using now() in a <asp:textbox>

  - by Anthony

  Can anyone help. I am using a formview in VS 2005. I have different elements in my form databound to a database and I am performing an INSERT SQL statement. No problem. The problem is that I am trying to enter the current date into the SQL statement and I am having a problem. I can add <%now()% to the "Text" property of the asp:Textbox. But when I do, then I can't bind the textbox to a specific database column. How do I do both???? I can do this: <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("Initiate_Date") %>' ></asp:TextBox> Or this: <asp:TextBox ID="TextBox2" runat="server" Text='<%# now() %>' ></asp:TextBox> But I don't know how to do both.

• Accidentally created a virus?

  - by Workshop Alex

  I've seen it happen reasonabley often: I write an application in Delphi and when I compile it, the virus-scanner tells me that I've created a virus and thus immediately deletes the executable again. It's annoying but reasonable easy to fix by doing a full rebuild, deleting the *.dcu files first and sometimes by simply waiting. It happens with Delphi 6, 7, 2005 and 2007, as far as I know. And Symantec, Kaspersky, McAfee and NOD32 have all been guilty of reporting these false positives. I know it's because Delphi adds timestamps to its DCU files and these timestamps end up in the final executable and apparently appear to be part of some random virus signature. I don't want to disable the virus-scanner, not even for a single folder or file. And I'm not really for a solution, but am wondering about the following: Do these false positives also occur with other compilers? Does it also happen with .NET executables? Do others also notice similar problems with Delphi?

• Coding issue in the 3D Buzz Hyperion tutorial.I am work

  - by Geno

  I'm following along with the tutorial. And we are currently coding the Item class. I am using the 2008 edition, while the tutorial uses 2005. The code I am having issue with is: public string Weight { get { return weight; } set { weight = value; } } earlier in the code, we had: private int Weight = 1; as you can see, they are both different variables, int, and string. I'm doing exactly as the tutorial shows, on mine, I get a conversion error, whereas in the tutorial, there are no errors, why is this? I'm doing exactly what the video shows.

• NHibernate - get List<long> representing primary keys?

  - by Nathan

  I have a situation where I definitely don't want to get the whole domain object. Basically, the entity has a primary key of long (.NET)/bigint(sql server 2005). I simply need to pass the primary key to an external system which will access the database directly - and since the list of ids could be large, I don't want to rehydrate the entire domain object just to get the Id. In linq2sql, I could accomplish this with a projection, but I am restricted to NHibernate 1.2.1.4000, which doesn't support Linq. Is there a way to accomplish this using NHibernate 1.2.1.4000? (I am open to using a named-query if that will work)

• Wrong shortcut icons on the desktop and in the programs menu

  - by Zenya

  When creating a program setup, I also put some documentation or readme files in it. However after the program is installed, I get wrong icons on the desktop and in the programs menu, as below: What I expected: I thought that for the registered file types (such as pdf, txt, doc, etc.) I don't need to set icons manually in the setup project. Am i wrong? As far as I know some other installers doesn't have such problem. Does anybody know how to fix this for Visual Studio? My environment is: Visual Studio 2005, C#, Windows XP Pro SP3

• Explicit initialization of struct/class members

  - by Zephon

  struct some_struct{ int a; }; some_struct n = {}; n.a will be 0 after this; I know this braces form of initialization is inherited from C and is supported for compatibility with C programs, but this only compiles with C++, not with the C compiler. I'm using Visual C++ 2005. In C this type of initialization struct some_struct n = {0}; is correct and will zero-initialize all members of a structure. Is the empty pair of braces form of initialization standard? I first saw this form of initialization in a WinAPI tutorial from msdn.

• Has anyone managed to get Visual Studio 2003 running on Windows 7?

  - by Jeremy White

  Yes, I know... I could set up a virtual machine running XP. Unfortunately our build environment is such that we need to be running VC2003, 2005 and 2008 concurrently and it would be much more convenient if I could run 2003 natively on Windows 7 for the few projects we have that require it. I realize some things may not be available in the IDE, but I was able to run 2003 under windows Vista and if I could get the same base level of functionality under Windows 7 I would be extremely happy. Right now I get an error opening the *.pdb file when I compile after switching vc2003 to run as Administrator under compatibility mode for XP SP 2. Thanks!

• buffer overflow with boost::program_options

  - by f4

  Hello, I have a problem using boost:program_options this simple program, copy-pasted from boosts' documentation : #include <boost/program_options.hpp> int main( int argc, char** argv ) { namespace po = boost::program_options; po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("compression", po::value<int>(), "set compression level") ; return 0; } fails with a buffer overflow. I have activated the "buffer security switch", and when I run it I get an "unknown exception (0xc0000409)" when I step over the line desc.add_options()... I use Visual Studio 2005 and boost 1.43.0. By the way it does run if I deactivate the switch but I don't feel comfortable doing so... unless it's possible to deactivate it locally. So do you have a solution to this problem? EDIT I found the problem I was linking against libboost_program_options-vc80-mt.lib which wasn't the good library.

• Are there any web application frameworks usable with .NET 2.0?

  - by adhocgeek

  Apologies if this has been asked many, many times before - I'm afraid I couldn't find any satisfactory answers. I'm stuck in an environment (a bank) where, although we have VS 2008 on the development machines, production machines are locked down to the .Net framework 2.0 and SQL Server 2005. Are there any modern application frameworks that I could employ? I've looked at things like Spring.NET, PureMVC and ASP.NET MVC (S#arp Arch?), but I don't really have the luxury of time to investigate in depth. I don't want to initiate a war over which framework might be best, I just want to know if there are any I can actually use.

• Win32 Thread Exits Unexpectedly

  - by sahs

  Hello, I'm writing a C++ application. I realized that one of my worker threads may terminate unexpectedly. The (VS 2005) debug log says: The thread 'Win32 Thread' (0x5d98) has exited with code -858993460 (0xcccccccc). I surrounded all the worker thread code with a try/catch block. So, if the reason was an exception, I would catch it. But I can't: try{ ... Connection* conn = connectionPool->getConnection(); // unexpected exit occurs here ... } catch(exception& e) { ... } I have ten threads running concurrently, and only one of them gets crashed after some time, while the others continue running (and getting new [OCCI] connections). Is there an exception type that is not caught by "exception"? Or what do I not know about threads/exceptions? Thanks.
