• Virtual Machine Performance - More RAM or More Processor?

  - by webworm

  When looking to improve Virtual Machine performance what would be better ... Increasing the available RAM or increasing the processor power? Here is my choice ... Core 2 Duo @ 2.4 GHz with 8 GB RAM and integrated graphics (Mac Book Pro 13") Core i7 @ 2.6 GHz with 4 GB RAM and 512 MB dedicated graphics (Mac Book Pro 15") I plan to run Windows x64 in the VM with SQL Server 2008, Visual Studio 2010, and SharePoint 2010. I am planning to run VMWare Fusion v3. I also didn't know if a dedicated graphics card makes a difference when using a Virtual Machine. Thank you.

• sql server 2005 reporting services-- how to use multiple datasets in report

  - by larryq

  Hi everyone, I'm new to SQL Server reporting services, and am trying to decipher an existing report. It's nothing too bad, but I notice it does have two report datasets defined. (They are generated via separate stored procedures) I'm trying to figure out where and how the report datasets are linked together so the Fields collection has both sets of columns available and the report has a single rowset to traverse. Is there a section in the report layout where a joining of datasets is defined? I'm using Visual Studio 2005 to design and preview the report fwiw. Thanks for your help!

• Size and position of the C# form.

  - by Vytas999

  I use Visual Studio .NET to create a Windows-based application. The application includes a form named CForm. CForm contains 15 controls that enable users to set basic configuration options for the application. I design these controls to dynamically adjust when users resize CForm. The controls automatically update their size and position on the form as the form is resized. The initial size of the form should be 650 x 700 pixels. If CForm is resized to be smaller then 500 x 600 pixels, the controls will not be displayed correctly. How I must ensure that users cannot resize CForm to be smaller than 500 x 600 pixels..?

• Code changes in the Dtsx file in an SSIS package not reflecting after deploying and running on the server

  - by SKumar

  I have some folder called Test-Deploy in which I keep all the dtsx files, manifest and configuration files. Whenever I want to deploy the ssis package, I run manifest file in this folder and deploy. My problem is I have to change one of the dtsx files out of it. So, I opened only that particular dtsx file BI studio, updated and built. After the build, I copied the dtsx file from bin folder and copied to my Test-Deploy folder. When I deployed and run this new package in the Test-Deploy folder, the changes I made are not reflecting in the result. I could not find any difference in the results before and after changing. My doubt is has it saved my previous dtsx file somewhere on the server and executing the same dtsx file instead of the new one?

• MFC resource.h command/message IDs

  - by ak

  Hi I'm working on an MFC application, that got pretty messy over years and over different teams of developers. The resource.h file, which contains all command/message mappings grew pretty big over time, and has lots of problems (like duplicate IDs). I am not proficient with MFC, so the question might sound pretty stupid... MSDN docs mention that Command IDs and Message IDs should not be less than WM_USER and WM_APP correspondingly. I saw that most of the command IDs in resource.h generated by Visual Studio begin around 100. Shouldn't this cause some interfering with MFC/Windows commands and messages, that overlap with the application defined IDs? For example, I have a command ID : #define ID_MY_ID 101 and there is a windows command that has the same ID. When MC send this command to the APP, it's handled like an application defined ID_MY_ID, and the app is taking unnecessary actions. Is it a possible scenario? Also, is there some third party tool that helps to profile the project resources?

• Tortoise SVN Icon Overlays Displaying Everywhere...Why?

  - by jwalkerjr

  Update: So, this turns out to have nothing to do with Tortoise SVN. I use Mozy.com for off-site backups and their new version includes these icon overlays. They can be disabled via the config options...or see here http://forum.pcmech.com/showthread.php?p=1385433. Thanks @OS for the answer. Been using Tortoise SVN for some time on my Vista box. Within the last few days (and after recently upgrading to 1.5.4) the icon overlays are displaying on all files. My exclude path is: * My include paths are: C:\Users\jw\Documents\Visual Studio 2008\Projects\SVNProjects* C:\Users\jw\Documents\VB Projects\SVNProjects* I haven't touched those settings in months. Any ideas? Help. Thanks.

• Implement a generic C++/CLI interface in a C# generic interface

  - by Florent

  I have a C++/CLI generic interface like this : using namespace System::Collections::Generic; namespace Test { generic <class T> public interface class IElementList { property List<T>^ Elements; }; } and I want to implement it in a C# generic interface like this : using Test; namespace U { public interface IElementLightList<T> : IElementList<T> where T : IElementLight { bool isFrozen(); bool isPastable(); } } This don't work, Visual Studio is not able to see C++/CLI IElementList interface ! I tested with a not generic C++/CLI interface and this work. What I missed ?

• Capturing USB Plug/Unplug events in Firemonkey

  - by radsdau

  [RAD Studio XE3 / C++] I have a FMX project running in Windows only at this stage, but I need to detect events when USB devices are connected and disconnected. I have a similar VCL app that can do this fine, but the Application-HookMainWindow is not exposed in FMX (only VCL). Is there an elegant way to handle this? Or do I have to hack some VCL stuff into my FMX app to make that work? I'd imagine I have to abstract it so I can support other platforms down the track. For the meantime though I need to get the Windows solution working. If the 'VCL hack' thing is required, how would I reference the vcl::Forms::Application from within my Fmx app? Cheers.

• Good HTML/CSS/PHP editor that is free and multi-platform?

  - by Earlz

  Hello, I have recently given up on using Visual Studio for Windows editing. See, PHP isn't really important as I have hardly any pages that use it, but in VS, if it smells PHP then it won't treat it as HTML and thus will all be plainly formatted.. so.. I'm looking for some sorta HTML/CSS/PHP editor that is free and multi-platform(so I can also use it at my home OpenBSD computer) And please don't suggest emacs or vi. I'm learning more and more of nvi, but I'm looking for a graphical editor right now. Can anyone suggest a good editor for my needs?

• [wxWidgets] How to store wxImage into database, using C++?

  - by Thomas Matthews

  I have some wxImages and I would like to store them into a BLOB (Binary Large OBject) field in a MySQL database. There are no methods in wxImage nor wxBitmap for obtaining the binary data as an array of unsigned char so I can load into the database. My current workaround is to write the image to a temporary file, then load the BLOB field directly from the file. Is there a more efficient method to load and store a wxImage object into a MySQL BLOB field? I am using MySql C++ connector 1.05, MS Visual Studio 2008, wxWidgets and C++.

• Does a WCF service with basicHttpBinding create a new connection for each request?

  - by Phil Wright

  I have a Silverlight client calling a WCF Service on an IIS web server. It uses the default basicHttpBinding setting for the calls. My client code has the usual Visual Studio generated proxy that is generated when using the 'Update Service Reference' menu option. Does every call to the service using that proxy use the same connection? Or does it create a connection each time a call is made and then close it down once the reply is received? As the client is actually making a SOAP call over HTTP I just assumed that every service request had a new connection created but I want to check if that is the case? (I need to know because if it creates a new connection each time then each request could end up at a different server because there are several servers being load balanced. It is uses a single connection for the duration of the proxy then I can assume they all end up at the same machine and so it would cache state.)

• Client App with WCF to consume ASMX

  - by BDotA

  I have a webservice with .NET 1.1 (old school ASMX) and I am creating a client app to connect to it and use its services. From what I remember from the last time I had used Visual studio -which was 2003 version!- I can add a WebReference to it and easily use it. Tried it . it still works. but it looks like things have changed in 2008 and now we also have WCF. so I can add it as a Service Reference. but with this new method I could not find a way to create an Instance object to the ASMX service and call its methods... how do we accomplish the same thing with WCF?

• Is it good to use .settings for storing controls text data?

  - by Zenya

  In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

• C# and Linq: Generating SQL Backup/Restore From Code

  - by mdvaldosta

  I'm working with a C# and Linq to SQL Winforms app and needed to integrate backup and restores through the program. I used SMO and got it working pretty smoothly. The issue, however, is that the app is deployed using ClickOnce, which I like very much - but since I had to include the dll's the download size jumped from 3mb = 15mb. I know they've only got to download it once, but it also sucks for me as Visual Studio 2010 seems to upload the dll's every time and that takes a while on AT&T broadband (eh). So, anyone have any suggestion on how I can work out an effective backup/restore solution without using SMO objects?

• Which is better for quickly developing small utilities? AutoIt or AutoHotKey?

  - by Abhijeet Pathak

  Which is better for quickly developing small utilities? AutoIt or AutoHotKey or something else? I need to develop some small software for which I think using some professional suite like Visual Studio will be overkill. Most of the macro recording tools like AutoIt or AutoHotKey provide enough power to write decent application. Plus they are small and free. Which option will be good? Using one of these tools or using some other small/free compiler?

• VS 11 with std::future - Is this a bug?

  - by cooky451

  I recently installed the Visual Studio 11 Developer Preview. While playing with threads and futures, I came around this setup: #include <future> #include <iostream> int foo(unsigned a, unsigned b) { return 5; } int main() { std::future<int> f = std::async(foo, 5, 7); std::cout << f.get(); } So, very simple. But since there are two arguments for "foo", VS 11 doesn't want to compile it. (However, g++ does: http://ideone.com/ANrPj) (The runtime error is no problem: std::future exception on gcc experimental implementation of C++0x) (VS 11 errormessage: http://pastebin.com/F9Xunh2s) I'm a little confused right now, since this error seems extremely obvious to me, even if it is a developer preview. So my questions are: Is this code correct according to the C++11 standard? Is this bug already known/reported?

• Licensing your code in Mono

  - by Jerry

  I'm working with some code in Visual Studio. My parter-in-crime fellow developer has suggested that the code also be available to work under Mono. I'm impresed witht he work that is already done in Mono, but I'm very new to Mono, so I don't know what it can/cannot do. I've already written a class in C# using the .NET LicenseManager object. It writes to the windows registry, so I know I'll have to modify it so that it will use some compiler flags like #if Win32 or #if MONO. My question is two-fold: 1) Does Mono implement the same LicenseManager class structure? 2) If so, how do you guys lock down your code using LicenseManager in Linux? (i.e. Write to files, use a hardware dongle, compare to hardware serials, etc??)

• Console output window in DLL

  - by user303907

  Hello, I am trying to redirect the output from my DLL to an external console window for easy debugging. I have been told about AllocConsole but I am not able to reproduce it, i.e. the console window does not appear. My current environment is Visual Studio 2005. I tried the following example which is gotten off the Internet, AllocConsole(); HANDLE han = GetStdHandle(STD_OUTPUT_HANDLE); WriteConsole(han,"hello",6,new DWORD,0); yet nothing happens. Can someone point me in the right direction if creating a console window via DLL is possible in the first place. Thanks in advance!

• .NET Database Apps: Your Preferred Setup

  - by mdvaldosta

  I'm struggling to settle into a pattern for developing typical database driven apps in C# and Visual Studio. There are so many ways to set them up, using drag/drop datasets and adapters or writing the queries manually in ADO.NET or Linq to SQL, Linq to Entities, to bind or not to data bind etc etc. Where to store the connection string, in app.config or in a method or both etc etc. So many tutorials and all of them are different. Everytime I write something I start hating the way it looks and works, so I scrap it and start over. It's getting a bit tedious. Maybe it's alittle of the OCD in me. Would any of you professional developers out there share your method of setting up and structuring your database logic and maybe some sample code? It's really how to go about organizing the code and the method(s) of interacting with SQL that I'm trying to get into a routine with, one that works and won't get me laughed at by someone reviewing it.

• ReturnUrl = Default.aspx for MVC?

  - by Cynthia

  I'm trying to secure my entire MVC site, so before the Home controller, I added an [Authorize] attribute. Now if you run it from Visual Studio or navigate using the root URL (e.g. http://localhost:2897) it does redirect to the login page, as expected. However the URL in the address bar after redirection looks like this: http://localhost:2897/Account/LogOn?ReturnUrl=%2fdefault.aspx%3f I haven't tested this out, seeing as I have not implemented my authentication code. However, this looks like a big problem to me, since I do not have a default.aspx in my project! My authentication tag in the web.config looks like this: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" defaultUrl="~/Home/Index" timeout="2880"/> </authentication> Why doesn't it pick up this route as the default ReturnUrl instead of default.aspx?
