• Is Windows 7 Home Premium edition sufficient for software development?

  - by Lee Englestone

  Is the Windows 7 Home Premium sufficient for software development? Development would be in Visual Studio 2010. I'm on a budget so would rather purchase 'Home Premium' rather than 'Professional' or 'Ultimate'. The Microsoft site says there is next to nothing functionality wise between them that developers would miss. Can anyone confirm or deny? BTW. Does it come with a version of IIS? I realize that this is not a technical question. But it is important to me and I'm sure other developers wonder the same thing. Cheers, -- Lee

• How can I set the Root Namespace property correctly in a C++/CLI application?

  - by Matthew Bowen

  I have a C++/CLI application in Visual Studio 2008 whose namespace follows the .NET guideline of CompanyName.TechnologyName[.Feature][.Design]. The problem is that there seems to be no way to set a multi-level namespace in the project's Root Namespace property. I have tried both CompanyName.TechnologyName and CompanyName::TechnologyName. It seems that I cannot have a Form control inside a namespace that is not the root namespace as this causes the resources it uses to not be found, thus to me it seems impossible to follow their guideline and be consistent with my C# applications. Is there a way to set this property to use multi-leveled namespaces or am I forced to use a root namespace that is simply one-level? Or is there a solution that I am overlooking? Any help would be appreciated. Thanks

• C#: Problem trying to resolve a class when two namespaces are simmilar.

  - by rally25rs

  I'm running into an issue where I can't make a reference to a class in a different namespace. I have 2 classes: namespace Foo { public class Class1 { ... } } namespace My.App.Foo { public class Class2 { public void SomeMethod() { var x = new Foo.Class1; // compile error! } } } The compile error is: The type or namespace name 'Class1' does not exist in the namespace 'My.App.Foo' In this situation, I can't seem to get Visual Studio to recognize that "Foo.Class1" refers to the first class. If I mouse-over "Foo", it shows that its trying to resolve that to "My.App.Foo.Class1" If I put the line: using Foo; at the top of the .cs file that contains Class2, then it also resolves that to "My.App.Foo". Is there some trick to referencing the right "Foo" namespace without just renaming the namespaces so they don't conflict? Both of these namespaces are in the same assembly.

• How to make VB to execute my SQL SP with parameters?

  - by fema

  Hi, I have a database in MS SQL Server 2008, I have Stored Procedures. One of them does an INSERT with parameters. It works in Server Management Studio. Now I'd like to make a button in Visual Basic 2008 that executes this SP. I have made a DataSet, it contains my 3 SP's, I can easily use 2 of them, because they return data, but the one I'm having trouble with doesn't. Could anyone please tell me how to make VB to execute it? (The command should look like this: "EXECUTE SP2 a, b, c, d".) Thanks in advance

• How to change object positions in an android layout?

  - by Pedro Santos

  Hi, I'm currently working on a very simple aplication, and I intended to make it change the visual aspect depending on the screen size. The application just has 6 buttons like this: http://www.freeimagehosting.net/uploads/e1efb4c4d0.jpg I'm using the AbsoluteLayout, and changing the x and y of the buttons with the methods offsetLeftAndRight and offsetTopAndBottom. I'm not changing the layout of the buttons in the xml file, so the all start in the same place. However, if I use this methods inside the onClickMethod they sometimes appear where I want them, sometimes don't (can't figure out why), but if i use them in the onCreate method, nothing happens. Can someone point me in the right direction? Thanks

• How do you create your own drag-n-drop GUI designer ?

  - by panzerschreck

  Hello I was looking at creating a UI for developing web forms, similar to the Netbeans Visual JSF form designer.It will be targeted to use GWT/GXT components.I am looking at a look very similar to VS/Netbeans. Any thoughts on where/how to start ? Initially, I would prefer to have it as a standalone application, later develop it as eclipse plugin. I have already evaluated the extjs designer and the eclipse plugin from instantiations, but i would prefer to have it developed on my own, as it looks challenging, Also, I have few custom components that have been developed. Thanks

• Using WINAPI ReadConsole

  - by Jim Fell

  I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application. CONSOLE_READCONSOLE_CONTROL tControl; char pStr[65536]; DWORD dwBufLen = 1; DWORD dwCtl; tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL ); tControl_c.nInitialChars = 0; tControl_c.dwControlKeyState = 0; tControl_c.dwCtrlWakeupMask = NULL; pBuf[0] = 0x00; do { ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl ); } while ( pStr[0] == 0x00 ); The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

• Use relative Path in Microsoft Surface application?

  - by Roflcoptr

  I convert my wave file into a mp3 file by the following code: internal bool convertToMp3() { string lameEXE = @"C:\Users\Roflcoptr\Documents\Visual Studio 2008\Projects\Prototype_Concept_2\Prototype_Concept_2\lame\lame.exe"; string lameArgs = "-V2"; string wavFile = fileName; string mp3File = fileName.Replace("wav", "mp3"); Process process = new Process(); process.StartInfo = new ProcessStartInfo(); process.StartInfo.FileName = lameEXE; process.StartInfo.Arguments = string.Format("{0} {1} {2}", lameArgs, wavFile, mp3File); process.Start(); process.WaitForExit(); int exitCode = process.ExitCode; if (exitCode == 0) { return true; } else { return false; } } This works, but now I'd like to not use the absolut path to the lame.exe but a relative path. I included a lame.exe in the folder /lame/ on the root of the project. How can I reference it?

• Customizing UISlider look

  - by tcurdt

  To customize the visual look of a UISlider you can set the thumb and track images. Part of the track images gets stretched to the appropriate with. From the documentation: A stretchable region sits between two end cap regions. The end caps define the portions of the image that remain as is and are not stretched. The stretchable region is a 1-point wide area between the end caps that can be replicated to make the image appear longer. Now the problem I have is that my stretchable region needs to be more than 1-point wide. (It's a pattern) Unfortunately the 1-point width seems to be hard coded in the SDK. Anyone having an idea how to work around this? Or will I have to write my own slider from scratch for this?

• Permission error while trying to access Sql from a web method

  - by Pavan Reddy

  I created a web service which has a few web methods which inturn performs inserts/updates/select from a Sql Server and return non-primitive types. To test the web methods I tried using the Open source tool .net web service studio When I test for the web methods, I get the following error - Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I searched for solutions and I tried a lot of approaches like setting up the permission levels, the trust level in config file etc. But the error still persists. Can anyone tell me what could be the reason for this error? I have tried toggling the permissions at all levels - Sql Server, web service etc. How can I fix this error?

• C# testing framework that works like JUnit in Eclipse?

  - by bluebomber357

  Hello all, I come from a Java/Eclipse background and I fear that I am spoiled by how easy it is to get JUnit and JMock running in Eclipse, and have that GUI with the bar and pass/fail information pop up. It just works with no hassle. I see a lot of great options for testing in C# with Visual Studio. NUnit looks really nice because it contains unit and mock testing all in one. The trouble is, I can't figure out how to get the IDE display my results. The NUnit documentation seems to show that it doesn't automatically show results through the VS IDE. I found http://testdriven.net/, which seems to trumpet that is makes VS display these stats and work with multiple frameworks, but it isn't open source. Is there anyway to get unit and mock testing working with the VS IDE like it does in Java with Eclipse?

• Using Sessions in WCF Services called from Silverlight

  - by Torbjörn Josefsson

  (Using Visual Studio 2008, and Silverlight 3) -I've really looked around for this one, and now I'm just confused by all the solutions that simply won't work for me. I'm trying to call a WCF service from a Silverlight client, which is no problem, but I can't get the service to handle sessions (I want to remember a few things about the callee between calls) I've gathered that basicHttpBinding is no good for sessions, and I haven't managed to make wsHttpBinding work... what's the matter? I would have thought this was a pretty basic thing people would want in their WCF services, or am I just completely muddle-headed not to see how it can be done?

• Lamda expression will not compile

  - by John Soer

  I am very confused I have this lamba expression tvPatientPrecriptionsEntities.Sort((p1, p2) => p1.MedicationStartDate.Value.CompareTo(p2.MedicationStartDate.Value)); Visual studio will not compile it and complains about syntax. I converted the lamba expression to an anonymous delegate as so tvPatientPrecriptionsEntities.Sort( delegate(PatientPrecriptionsEntity p1, PatientPrecriptionsEntity p2) { return p1.MedicationStartDate.Value.CompareTo(p2.MedicationStartDate.Value); } ); and it works fine. The project is uses the .net 3.5 framework and I have a reference to system.linq.

• VSTO install package How to check for prerequisites and skip them

  - by ticky

  I created Setup project for my Excel add-in project according to the article: Deploying a Visual Studio Tools for the Office System 3.0 Solution for the 2007 Microsoft Office System Using Windows Installer http://msdn.microsoft.com/en-us/library/cc563937(office.12).aspx I add prerequisites such as 2007 Interop assemblies(Office2007PIA) and when I run my setup file it does install it. But the problem is : That my setup ALWAYS installs it even if my computer already has Office2007PIA. How can I configure my setup project that it will first check if Office2007PIA is installed and continue the installation of my project without installing Office2007PIA? Thanks!

• 2-byte (UCS-2) wide strings under GCC

  - by Seva Alekseyev

  Hi all, when porting my Visual C++ project to GCC, I found out that the wchar_t datatype is 4-byte UTF-32 by default. I could override that with a compiler option, but then the whole wcs* (wcslen, wcscmp, etc.) part of RTL is rendered unusable, since it assumes 4-byte wide strings. For now, I've reimplemented 5-6 of these functions from scratch and #defined my implementations in. But is there a more elegant option - say, a build of GCC RTL with 2-byte wchar-t quietly sitting somewhere, waiting to be linked? The specific flavors of GCC I'm after are Xcode on Mac OS X, Cygwin, and the one that comes with Debian Linux Etch.

• SendMessage (F4) fails when sending it to window

Thanks in acvance a lot... Olli

• Lines-of-code counting for many C# solutions

  - by Eric

  I am currently researching a solution for counting lines of code in C#. I pretty much need a combination of the following two tools: http://richnewman.wordpress.com/2007/07/01/c-and-vbnet-line-count-utility/ http://www.locmetrics.com/index.html My problem is that I need to recursively scan a folder containing a lot of visual studio solutions. So can't really use the first tool without any major work on its code, as it's only able to scan a single solution at a time. But I also need to split the results for each solution, preferably even the contained projects. This disqualifies the second tool I found. I also found NDepend which suffers from the same problem. Do you know of any free tools that do what I need? I am unable to find anything suitable.

• IE7 ignoring margin in a div following an absolute positioned div

  - by 0al0

  I have two divs inside a container, the first one has absolute positioning. In ie7, the second div apparently ignores the top margin. Padding seems to work fine, but for visual reasons I have to use margin. I know the culprit is the absolute positioned div because if i remove it the following div works fine. This is only happening in ie7 (not even in ie6). Help! Edit: I just found a solution which consists of giving the parent div padding-top just for ie7. So I would just like to know why does this happen, and if there is one, a cleaner solution, but I dont need more dirty hacks..

• How to insert arabic characters into sql database?

  - by Pavan Reddy

  How can I insert arabic characters into sql database? I tried to insert arabic data into a table and the arabic characters in the insert script were inserted as '??????' in the table. I tried to directly paste the data into the table through sql management studio and the arabic characters was successfully and accurately inserted. I looked around for resolutions for this problems and some threads suggested changing the datatype to nvarchar instead of varchar. I tried this as well but without any luck. How can we insert arabic characters into sql database?

• Deploying .NET components (upgrade the component for only a single client application)

  - by Vytas999

  I use Visual Studio .NET to create a component that will be shared by two client applications. Eventually, I plan to deploy new version of this component. However, not all of the new versions will be compatible with both client applications. When I deploy component and the client applications, I must ensure that I can upgrade the component for a single client application. I must also minimize the need for configuration changes when I deploy new version of the component. What are possible ways to achieve this goal?

Sifr? Cufon? Images? What do people recommend in terms of SEO and visual niceties?

• Mscorcfg.msc .net Configuration Tools problem

  - by vijay shiyani

  I'm trying to run Microsoft's .NET Framework Configuration Tool (Mscorcfg.msc). I have Visual Studio 2008 installed. I also have the following installed on my PC: Microsoft .Net Framework v1.0.3705 Microsoft .Net Framework 2.0 Service Pack 2 Microsoft .Net Framework 3.0 Service Pack 2 Microsoft .Net Framework 3.5 SP1 Microsoft .Net Framework v4.0.30319 I'm not sure why, but I can't start "Mscorcfg.msc" the usual way (as suggested in the http://msdn.microsoft.com/en-us/library/2bc0cxhc(VS.80).aspx and http://msdn.microsoft.com/en-us/library/2bc0cxhc.aspx URL). I looked for "Mscorcfg.msc" on my PC and found only 1 occurence (in the C:\WINDOWS\ServicePackFiles\i386 folder). When I double-click on the .msc file in Windows Explorer, I get the "MMC could not create the snap-in." message. What should I do ? Thanks

• c# object initializer complexity. best practice

  - by Andrew Florko

  I was too excited when object initializer appeared in C#. MyClass a = new MyClass(); a.Field1 = Value1; a.Field2 = Value2; can be rewritten shorter: MyClass a = new MyClass { Field1 = Value1, Field2 = Value2 } Object initializer code is more obvious but when properties number come to dozen and some of the assignment deals with nullable values it's hard to debug where the "null reference error" is. Studio shows the whole object initializer as error point. Nowadays I use object initializer for straightforward assignment only for error-free properties. How do you use object initializer for complex assignment or it's a bad practice to use dozen of assigments at all? Thank you in advance!

• Why are framework dlls repeated in several places?

  - by Xose Lluis

  After installing .Net 4 and getting some questions that were already answered here I also realized how the Framework dlls are repeated in several places for the different Framework versions (this is not new, it happens with previous versions, but hadn't paid attention to it until now) 1 - GAC: %systemroot%\assembly 2- Framework installation directory: %systemroot%\Microsoft.NET\Framework\v... 3- and if you have the Windows SDK installed, also in: C:\Program Files\Microsoft SDKs\Windows\ I think the last ones are the so called "Reference Assemblies" and have extra metadata to aid Visual Studio, but what about location number 2? Why are assemblies repeated there?
