• How can I manage building library projects that produce both a static lib and a dll?

  - by Scott Langham

  I've got a large visual studio solution with ~50 projects. There are configurations for StaticDebug, StaticRelease, Debug and Release. Some libraries are needed in both dll and static lib form. To get them, we rebuild the solution with a different configuration. The Configuration Manager window is used to setup which projects need to build in which flavours, static lib, dynamic dll or both. This can by quite tricky to manage and it's a bit annoying to have to build the solution multiple times and select the configurations in the right order. Static versions need building before non-static versions. I'm wondering, instead of this current scheme, might it be simpler to manage if, for the projects I needed to produce both a static lib and dynamc dll, I created two projects. Eg: CoreLib CoreDll I could either make both of these projects reference all the same files and build them twice, or I'm wondering, would it be possible to build CoreLib and then get CoreDll to link it to generate the dll? I guess my question is, do you have any advice on how to structure your projects in this kind of situation? Thanks.

• .NET ServiceInstaller get too much time for uninstall services

  - by rodnower

  Hello, we have some Setup Project wrote in Visual Studio 2008 in C# that installs and uninstalls services with ServiceInstaller class. When I install the services this don't get too much time, but when I uninstall with following code the process for each service get few seconds (and we have many services): ServiceInstaller si = new ServiceInstaler(); string path = string.Format("/assemblypath={0}", strServiceExecutablePath); string[] cmdline = { path }; InstallContext context = new InstallContext(string.Empty, cmdline); si.Context = context; si.ServiceName = strServiceName; si.Uninstall(null); Some one know why? Here I want to ask some related question. What difference between working of: InstallUtill /u exePath when it uninstall service and: sc delete serviceName And why when I delete some record from registry from CurrentControlSet\services I still see the service in services.msc but with: <Failed to read description. Error code:2 In description? From where I need to delete service manually for delete it complitely? Thank you for ahead.

• WCF consumed as WebService adds a boolean parameter?

  - by Martín Marconcini

  I've created the default WCF Service in VS2008. It's called "Service1" public class Service1 : IService1 { public string GetData( int value ) { return string.Format("You entered: {0}", value); } public CompositeType GetDataUsingDataContract( CompositeType composite ) { if ( composite.BoolValue ) { composite.StringValue += "Suffix"; } return composite; } } It works fine, the interface is IService1: [ServiceContract] public interface IService1 { [OperationContract] string GetData( int value ); [OperationContract] CompositeType GetDataUsingDataContract( CompositeType composite ); // TODO: Add your service operations here } This is all by default; Visual Studio 2008 created all this. I then created a simple Winforms app to "test" this. I added the Service Reference to my the above mentioned service and it all works. I can instanciate and call myservice1.GetData(100); and I get the result. But I was told that this service will have to be consumed by a Winforms .NET 2.0 app via Web Services, so I proceeded to add the reference to a new Winforms .NET 2.0 application created from scratch (only one winform called form1). This time, when adding the "web reference", it added the typical "localhost" one belonging to webservices; the wizard saw the WCF Service (running on background) and added it. When I tried to consume this, I found out that the GetData(int) method, was now GetData(int, bool). Here's the code private void button1_Click( object sender, EventArgs e ) { localhost.Service1 s1 = new WindowsFormsApplication2.localhost.Service1(); Console.WriteLine(s1.GetData(100, false)); } Notice the false in the GetData call? I don't know what that parameter is or where did that come from, it is called "bool valueSpecified". Does anybody know where this is coming from? Anything else I should do to consume a WCF Service as a WebService from .NET 2.0? (winforms).

• How to handle 30k files in a project which requires them?

  - by Jeremiah

  Visual Studio 2010 RC - Silverlight Application We have a library of images that we need to have access to. They are given to us from a vendor (through an installer) and they are not in a database, they are files in a folder (a very large monster of a folder). We do not control when the images change, so the vendor needs to be able to override them individually. We get updates frequently enough from this vendor to state that these images change "randomly" and without our (programmer) knowledge. The problem: I don't want 30K images in SVN. Heck, I don't even want to imagine them in my Solution. However, our application requires them in order to run properly. So, our build/staging servers need access to these images (we have two build servers). The Question: How would you handle it when your application will not work as specified without access to each of 30k images and you don't control when those images change? I'm do not want to have a crazy large SVN repository. Because I don't know when any of these images change, I really don't want them in my solution (definitely do not want a large solution, either). I also don't want a bunch of manual steps to do every time these images change. Our mantra, up to this point, has always been, any developer could download from SVN, compile and run our app. These images are going to kill that mantra. I'm tempted to make a WCF service that will return images if they exist and a dummy image if they don't. This way all dev boxes will return a dummy image and our build/staging/production boxes will return real images (ones that actually have the vendor's image installer installed on). This has to be a solved problem. What have other people done to handle these types of problems? I'm open to suggestions.

• Can anyone provide a good "idiot's guide" to creating an installer in VS2008 (C#) Pro?

  - by paxdiablo

  I have Visual C# 2008 Professional and have developed the first half of a C# application (console mode) with the second half in progress now (GUI). I'm looking for an easy path to creating an installer for it. What are the steps that need to be taken to produce a professional installer? There's a similar question here regarding the Express edition but I have Pro, and I would like as much as possible to stick with just the standard VS stuff (if you think you can convince me that a third party installer creator is much better than a VS-only solution, give it a shot, by all means). Keep in mind that I have no interest in upgrading to VS2010 yet, even if it's a hundred times easier to create an installer. That can come later, when the revenue starts rolling in :-) Also be aware that the GUI component of this application is a totally separate executable from the console part. The console part is a simple "open file 1, do some work on it, write file 2" type and the GUI is a fairly standard "open file, do some stuff" beast so there's no tricky or wildly undocumented behaviour happening. Basically, I'm looking for (at least) the following: professional looking installer. ability to specify where the application files go. changes to the registry to allow double-clicks on my file extension to open the GUI app with the file as an argument. needs to install everything required (my stuff, .Net if required, and so on).

• How to create a progress bar while downloading a file using the windows API?

  - by Jorge Chayan

  i'm working on an application in MS Visual C++ using Windows API that must download a file and place it in a folder. I have already implemented the download using URLDownloadToFile function, but i want to create a PROGRESS_CLASS progress bar with marquee style while the file is being downloaded, but it doesn't seems to get animated in the process. This is the function I use for downloading: BOOL SOXDownload() { HRESULT hRez = URLDownloadToFile(NULL, "url","C:\\sox.zip", 0, NULL); if (hRez == E_OUTOFMEMORY ) { MessageBox(hWnd, "Out of memory Error","", MB_OK); return FALSE; } if (hRez != S_OK) { MessageBox(hWnd, "Error downloading sox.", "Error!", MB_ICONERROR | MB_SYSTEMMODAL); return FALSE; } if (hRez == S_OK) { BSTR file = SysAllocString(L"C:\\sox.zip"); BSTR folder = SysAllocString(L"C:\\"); Unzip2Folder(file, folder); ::MessageBoxA(hWnd, "Sox Binaries downloaded succesfully", "Success", MB_OK); } return TRUE; } Later I call inside WM_CREATE (in my main window's message processor): if (!fileExists("C:\\SOX\\SOX.exe")) { components[7] = CreateWindowEx(0, PROGRESS_CLASS, NULL, WS_VISIBLE | PBS_MARQUEE, GetSystemMetrics(SM_CXSCREEN) / 2 - 80, GetSystemMetrics(SM_CYSCREEN) / 2 + 25, 200, 50, hWnd, NULL, NULL, NULL); SetWindowText(components[7], "Downloading SoX"); SendMessage(components[7], PBM_SETRANGE, 0, (LPARAM) MAKELPARAM(0, 50)); SendMessage(components[7], PBM_SETMARQUEE, TRUE, MAKELPARAM( 0, 50)); SOXDownload(); SendMessage(components[7], WM_CLOSE, NULL, NULL); } And as I want, I get a tiny progress bar... But it's not animated, and when I place the cursor over the bar, the cursor indicates that the program is busy downloading the file. When the download is complete, the window closes as i requested: SendMessage(components[7], WM_CLOSE, NULL, NULL); So the question is how can I make the bar move while downloading the file? Considering that i want it done with marquee style for simplicity. Thanks in advance.

• Ways to access a 32bit DLL from a 64bit exe

  - by bufferz

  I have a project that must be compiled and run in 64 bit mode. Unfortunately, I am required to call upon a DLL that is only available in 32 bit mode, so there's no way I can house everything in a 1 Visual Studio project. I am working to find the best way to wrap the 32 bit DLL in its own exe/service and issue remote (although on the same machine) calls to that exe/service from my 64 bit app. My OS is Win7 Pro 64 bit. The required calls to this 32 bit process are several dozen per second, but low data volume. This is a realtime image analysis application so response time is critical despite low volume. Lots of sending/receiving single primitives. Ideally, I would host a WCF service to house this DLL, but in a 64 bit OS one cannot force the service to run as x86! Source. That is really unfortunate since I timed function calls to the WCF service to be only 4ms on my machine. I have experimented with named pipes is .net. I found them to be 40-50 times slower than WCF (unusable for me). Any other options or suggestions for the best way to approach my puzzle?

• What's a good way to do testing a plug-in on multiple Windows and Outlook versions?

  - by Andrei

  Hello, We're building a plug-in for Outlook that should work on multiple Windows versions (XP, Vista, 7) and also with different Outlook versions (2003, 2007, 2010). The testing problem I am facing right now, is that I can't figure out a good/convenient/thorough way to test the application on multiple Windows and Outlook versions. At the moment, I have a VirtualBox which runs many virtual machines, with different Windows versions and Outlook versions. So I would have a virtual machine with Windows 7 testing Outlook 2010, and another one with Windows 7 testing Outlook 2007, Windows Vista with Outlook 2010 and so on, going through some of the possible combinations. It kind of gets the job done, although it is cumbersome and takes a long time to test. Some of the testing included in the application is unit testing, but this is also rather tied in with the machine I test it on (windows 7 with outlook 2010). For example, I was using ManagementObject recently, which worked fine on my system (and thus passed the unit test for that method), however, using that object threw an exception in another person's system, which crashed the application. I work on Visual Studio 2010 Ultimate. The questions: Is there a more elegant way to make the testing process more streamline and more efficient? Any other testing methods you recommend? How would you deal with this problem? Thanks! Looking forward to your replies.

• Localization of DisplayNameAttribute

  - by PowerKiKi

  Hi, I am looking for a way to localize properties names displayed in a PropertyGrid. The property's name may be "overriden" using the DisplayNameAttribute attribute. Unfortunately attributes can not have non constant expressions. So I can not use strongly typed resources such as: class Foo { [DisplayAttribute(Resources.MyPropertyNameLocalized)] // do not compile string MyProperty {get; set;} } I had a look around and found some suggestion to inherit from DisplayNameAttribute to be able to use resource. I would end up up with code like: class Foo { [MyLocalizedDisplayAttribute("MyPropertyNameLocalized")] // not strongly typed string MyProperty {get; set;} } However I lose strongly typed resource benefits which is definitely not a good thing. Then I came across DisplayNameResourceAttribute which may be what I'm looking for. But it's supposed to be in Microsoft.VisualStudio.Modeling.Design namespace and I can't find what reference I am supposed to add for this namespace. Anybody know if there's a easier way to achieve DisplayName localization in a good way ? or if there is as way to use what Microsoft seems to be using for Visual Studio ?

• How to prevent VC++ 9 linker from linking unnecessary global variables?

  - by sharptooth

  I'm playing with function-level linking in VC++. I've enabled /OPT:REF and /OPT:ICF and the linker is happy to eliminate all unused functions. Not so with variables. The following code is to demonstrate the problem only, I fully understand that actually having code structured that way is suboptimal. //A.cpp SomeType variable1; //B.cpp extern SomeType variable1; SomeType variable2; class ClassInB { //actually uses variable1 }; //C.cpp extern SomeType variable2; class ClassInC { //actually uses variable2; }; All those files are compiled into a static lib. The consumer project only uses ClassInC and links to the static library. Now comes the VC++ 9 linker. First the linker sees that C.obj references variable2 and includes B.obj. B.obj references variable1, so it includes A.obj. Then the unreferenced stuff elimination phase starts. It removes all functions in A.obj and B.obj, but not the variables. Both variable and variable2 are preserved together with their static initializers and deinitializers. That inflates the image size and introduces a delay for running the initializers and deinitializes. The code above is oversimplified, in actual code I really can't move variable2 into C.cpp easily. I could put it into a separate .cpp file, but that looks really dumb. Is there any better option to resolve the problem with Visual C++ 9?

• How do you get the solution directory in C# (VS 2008) in code?

  - by IsaacB

  Hi, Got an annoying problem here. I've got an NHibernate/Forms application I'm working through SVN. I made some of my own controls, but when I drag and drop those (or view some form editors where I have already dragged and dropped) onto some of my other controls, Visual studio decides it needs to execute some of the code I wrote, including the part that looks for hibernate.cfg.xml. I have no idea why this is, but (sometimes!) when it executes the code during my form load or drag and drop it switches the current directory to C:\program files\vs 9.0\common7\ide, and then nhibernate throws an exception that it can't find hibernate.cfg.xml, because I'm searching for that in a relative path. Now, I don't want to hard code the location of hibernate.cfg.xml, or just copy hibernate.cfg.xml to the ide directory (which will work). I want a solution that gets the solutions directory while the current directory is common7\ide. Something that will let someone view my forms in the designer on a fresh checkout to an arbitrary directory on an arbitrary machine. And no, I'm not about to load the controls in code. I have so many controls within controls that it is a nightmare to line everything up without it. I tried a pre build event that made a file that has the solution directory in it, but of course how can I find that from common7\ide? All the projects files need to be in the solution directory because of svn. Thanks for your help guys, I've already spent a few hours fiddling with this in vain.

• Automatic adition of `using` in CodeRush.

  - by drasto

  I just installed CodeRush Pro (evaluation trial) for Visual Studio and I can say I like it much so far. Comparing to Resharper there is only one type of feature I'm really missing. It is the way CodeRush deals with using. When I type some class name that is not declared in some package listed in using, CodeRush underlines it red as an error(what it is) but if I hover over it with cursor it does not offer me to add using, it merely says it is "Undeclared element". I have to use VS default using addition (move caret to the identifier, hover cursor over that really small box that appears under first letter, click the button that appears and choose for example using System form a drop down menu). Is there a way how to configure CodeRush to offer mi add using when I hover a cursor over highlighted "issue"(that says Undeclared element)? The second part of this is that Resharper has somethink called Type name completion. It some improved intellisense. Lets say you have no using declaration in your file. Then you type something like ICompar and press CTRL+SPACE. Of cause there will be no suggestions. But with Resharper you can press CTRL+ALT+SPACE and you get suggestions of all classes starting with ICompar even if they are not in using. When you choose one of them the correct using is automatically added for you. Is there a way to make CodeRush behave this way ?

• Could this C cast to avoid a signed/unsigned comparison make any sense?

  - by sharptooth

  I'm reviewing a C++ project and see effectively the following: std::vector<SomeType> objects; //then later int size = (int)objects.size(); for( int i = 0; i < size; ++i ) { process( objects[i] ); } Here's what I see. std::vector::size() returns size_t that can be of some size not related to the size of int. Even if sizeof(int) == sizeof(size_t) int is signed and can't hold all possible values of size_t. So the code above could only process the lower part of a very long vector and contains a bug. That said I'm curious of why the author might have written this? My only guess is that first he omitted the (int) cast and the compiler emitted something like Visual C++ C4018 warning: warning C4018: '<' : signed/unsigned mismatch so the author though that the best way to avoid the compiler warning would be to simply cast the size_t to int thus making the compiler shut up. Is there any other possible sane reason for that C cast?

• Properties in User-Control Ctor are duplicated to the hosting form

  - by fortis

  An annoying behavior of Visual Studio (2008)'s designer is to duplicate any property of a control, which is set inside the control's constructor code to the InitializeComponent() method of the hosting form. For example, if I create a new user control and write the following line in its Ctor: this.Text = "Hard Coded Name"; then this same line will appear inside the InitializeComponent() method of any form hosting this control. As long as it's about this kind of properties, it's only annoying because if I were to change the Text property inside the control to: "Better Hard Coded Name", I'd have to go over all hosting controls and manually change the Text value over there too. The real problem is with ".Add(something)" properties - like if my control is a TableLayoutPanel and I want it to have a certain number of columns and rows. Any col or row style set inside the user control will be duplicated in the hosting form and we end up with having twice as wanted. The count (e.g. ColumnCount) will be as planned but if I were to add cols later on, things will get messy. Is there a way to signal VS's designer not to duplicate properties? What can I do to avoid this behavior?

• Why is joining two vectors simply not working?

  - by Jim

  I have two vectors of MyObj structs. MyObj is defined as follows: struct MyObj { float x, y; unsigned int data[8]; unsigned int tmp[1]; MyObj(const MyObj &m) { x = m.x; y = m.y; tmp[0] = 0; for (int i = 0; i < 8; ++i) { data[i] = m.data[i]; } } }; I then have two vectors... vector<MyObj> v1; vector<MyObj> v2; // both get data eventually. v1.insert(v1.end(), v2.begin(), v2.end()); v2 has 3535004 elements in my experiment. v1 is similarly sized. I've also tried building a new vector and just using .push_back to build it from both vectors. Essentially, when I try to merge the two vectors I just get an error from visual studio saying "Debug error! R6010, abort() has been called". Very non-useful... So my question is: what could be causing this error, and how can I solve it? Thank you

• Managing My Database in Source Control

  - by Jason

  As I am working with a new database project (within VS2008), and as I have never developed a database from scratch, I immediately began looking into how to manage a database within source control (in this case, Subversion). I found some information on SO, including this post: Keeping development databases in multiple environments in sync. One of the answers in particular pointed to a number of a links, all of which had good, useful information. I was reading a series of posts by K. Scott Allen which describe how he manages database change. From my reading (and please pardon the noobishness of my question), it seems as though the database itself is never checked into a repository. Rather, scripts that can build the database, along with test data (which is also populated from scripts) is checked into the repository. Ultimately, this means that, when a developer is testing his or her app, these scripts, which are part of the build process, are run. This ensures that the database is up-to-date, but is also run locally from every developer's machine. This makes sense to me (if I am indeed reading that correctly). However, if I am missing something, I would appreciate correction or additional guidance. In addition, another question I wanted to ask - does this also mean that I should NOT check in the mdf or ldf files that are created from Visual Studio? Thanks for any help and additional insight. Always appreciated.

• C++ Type error with Object versus Object reference

  - by muddybruin

  I have the following function (which worked in Visual Studio): bool Plane::contains(Vector& point){ return normalVector.dotProduct(point - position) < -doubleResolution; } When I compile it using g++ version 4.1.2 , I get the following error: Plane.cpp: In member function âvirtual bool Plane::contains(Vector&)â: Plane.cpp:36: error: no matching function for call to âVector::dotProduct(Vector)â Vector.h:19: note: candidates are: double Vector::dotProduct(Vector&) So as you can see, the compiler thinks (point-position) is a Vector but it's expecting Vector&. What's the best way to fix this? I verified that this works: Vector temp = point-position; return normalVector.dotProduct(temp) < -doubleResolution; But I was hoping for something a little bit cleaner. I heard a suggestion that adding a copy constructor might help. So I added a copy constructor to Vector (see below), but it didn't help. Vector.h: Vector(const Vector& other); Vector.cpp: Vector::Vector(const Vector& other) :x(other.x), y(other.y), z(other.z), homogenous(other.homogenous) { }

• Good C++ array class for dealing with large arrays of data in a fast and memory efficient way?

  - by Shane MacLaughlin

  Following on from a previous question relating to heap usage restrictions, I'm looking for a good standard C++ class for dealing with big arrays of data in a way that is both memory efficient and speed efficient. I had been allocating the array using a single malloc/HealAlloc but after multiple trys using various calls, keep falling foul of heap fragmentation. So the conclusion I've come to, other than porting to 64 bit, is to use a mechanism that allows me to have a large array spanning multiple smaller memory fragments. I don't want an alloc per element as that is very memory inefficient, so the plan is to write a class that overrides the [] operator and select an appropriate element based on the index. Is there already a decent class out there to do this, or am I better off rolling my own? From my understanding, and some googling, a 32 bit Windows process should theoretically be able address up to 2GB. Now assuming I've 2GB installed, and various other processes and services are hogging about 400MB, how much usable memory do you think my program can reasonably expect to get from the heap? I'm currently using various flavours of Visual C++.

• How to get VC# to rebuild auto-generated .cs files?

  - by Jive Dadson

  I imagine this question has been asked and answered, but I cannot find it. I wanted to make a simple GUI to interface to a windows 7 command. I usually use Wx, but since this was to be a windows-only thing, I decided to see if I could whip it out real fast using Visual C# 2010 Express, which I had never used before. Things started off just great. I created a form, put a few buttons and text boxes and such on it, and hit Debug. It came up and ran just like that. No muss, no fuss. So I then designed the form just the way I wanted it, renamed the controls from "Button1" and so forth to meaningful names. But now it's a mess. By clicking around, I discovered that VC# had auto-generated two files called Form1.cs and Form1.Designer.cs. The later contains the bindings between functions and the events generated from user-clicks etc., and the former contains no-op code for those functions, for me to complete. Problem is, the names are all still the original "Button1" and so forth, not the new ones, and the new controls I added after running the first time do not appear at all. I want it to regenerate all that stuff afresh from the finished form. How to?

• How to debug properly and find causes for crashes?

  - by Newbie

  I dont know what to do anymore... its hopeless. I'm getting tired of guessing whats causing the crashes. Recently i noticed some opengl calls crashes programs randomly on some gfx cards. so i am getting really paranoid what can cause crashes now. The bad thing on this crash is that it crashes only after a long time of using the program, so i can only guess what is the problem. I cant remember what changes i made to the program that may cause the crashes, its been so long time. But luckily the previous version doesnt crash, so i could just copypaste some code and waste 10 hours to see at which point it starts crashing... i dont think i want to do that yet. The program crashes after i make it to process the same files about 5 times in a row, each time it uses about 200 megabytes of memory in the process. It crashes at random times while and after the reading process. I have createn a "safe" free() function, it checks the pointer if its not NULL, and then frees the memory, and then sets the pointer to NULL. Isn't this how it should be done? I watched the task manager memory usage, and just before it crashed it started to eat 2 times more memory than usual. Also the program loading became exponentially slower every time i loaded the files; first few loads didnt seem much slower from each other, but then it started rapidly doubling the load speeds. What should this tell me about the crash? Also, do i have to manually free the c++ vectors by using clear() ? Or are they freed after usage automatically, for example if i allocate vector inside a function, will it be freed every time the function has ended ? I am not storing pointers in the vector. -- Shortly: i want to learn to catch the damn bugs as fast as possible, how do i do that? Using Visual Studio 2008.

• How to use project which is already in VSS?

  - by shekhar

  Hi, I am trying to add my project under source control. I am using "Microsoft VSS 6.0" for it. My problem is, there is one project in VSS which I had copied on my system using 'Get Latest Version' to C:\latest_version directory. Then I copied that entire project in other directory (C:\working) and deleted the directory where I had taken latest version of it (C:\latest_version). Now everytime I make any changes in code and want to do check in, I need to check out that particular file in some folder, copy-replace that file with my new file and check-in. Can we do all this through visual studio? I saw some tutorials which describe how to add project to VSS but in my case project is already is in VSS and I just want to link it with my project. Is it possible? I dont know whether I am using VSS correctly or not. I would like to know how do people usually use it? How to do check-in , check-out? Thanks in advance !!

  If I have a line like this ContentRepository.Update(existing); that goes into datastore repository to update some object and I have a try..catch block in this Update function like this: string file = XmlProvider.DataStorePhysicalPath + o.GetType().Name + Path.DirectorySeparatorChar + o.Slug + ".xml"; DataContractSerializer dcs = new DataContractSerializer(typeof (BaseContentObject)); using ( XmlDictionaryWriter myWriter = XmlDictionaryWriter.CreateTextWriter(new FileStream(file, FileMode.Truncate, FileAccess.Write), Encoding.UTF8)) { try { dcs.WriteObject(myWriter, o); myWriter.Close(); } catch (Exception) { // if anything goes wrong, delete the created file if (File.Exists(file)) File.Delete(file); if(myWriter.WriteState!=WriteState.Closed) myWriter.Close(); } } then why would Visual Studio go on with calling Update() if I click "Stop" in debugging session on the above line? For instance, I came to that line by going line by line pressing F10 and now I'm on that line which is colored yellow and I press Stop. Apparently what happens is, VS goes to execute the Update() method and somehow figures out something gone wrong and goes into "catch" and deletes the file, which is wrong, because I want my catch to work when there is a true exception not when I debug a program and force to stop it.

• Change Default Winform Icon Across Entire App

  - by Kyle Gagnet

  Can I change the default icon used on a Winform? Most of my forms have their icon property set to a custom icon. For the few forms that slip through the cracks, I don't want the generic "hey look, he made this in visual studio" icon. One solution is to tediously check every one of my forms to make sure they either have a custom icon set or have ShowIcon set to False. Another solution is to have every one of my forms inherit from a base class that sets a custom icon in the constructor. Aside from those solutions, what other options do I have? EDIT: I was hoping there would be a way to replace the source of the stock icon with my own. Is it in a resource file somewhere? Or is it embedded in a .NET dll that I can't (or really, really shouldn't) modify? BOUNTY EDIT: Is there a way to accomplish this without editing or writing a single line of code? I don't care how impractical, complicated, waste-of-time the solution is... I just want to know if it's possible. I need to satisfy my curiosity.

• How to make a Custom Data Generator for SQL XML DataType.

  - by Keith Sirmons

  Howdy, I am using Visual Studio 2010 and am playing around with the Database Projects. I am creating a DataGenerationPlan to insert data into a simple table, in which one of the column datatypes is XML. Out of the box, the generation plan uses the Regular Expression generator and generates something like this : HGcSv9wa7yM44T9x5oFT4pmBkEmv62lJ7OyAmCnL6yqXC2X.......... I am looking at creating a custom data Generator for this data type and have followed this site for the basics: http://msdn.microsoft.com/en-us/library/aa833244.aspx This example works if I am creating a string datatype and using it for a nvarchar datatype. What do I need to change to hook this Generator to the XML Datatype? Below are my code files. The string property works for nvarchar. The XElement property does not work for the xml datatype, and the RecordXMLDataGenerator is not listed as an option in the Generator column for the generation plan. CustomDataGenerators: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Data.Schema.Tools.DataGenerator; using Microsoft.Data.Schema.Extensibility; using Microsoft.Data.Schema; using Microsoft.Data.Schema.Sql; using System.Xml.Linq; namespace CustomDataGenerators { [DatabaseSchemaProviderCompatibility(typeof(SqlDatabaseSchemaProvider))] public class RecordXMLDataGenerator : Generator { private XElement _RecordData; [Output(Description = "Generates string of XML Data for the Record.", Name = "RecordDataString")] public string RecordDataString { get { return _RecordData.ToString(SaveOptions.None); } } [Output(Description = "Generates XML Data for the Record.", Name = "RecordData")] public XElement RecordData { get { return _RecordData; } } protected override void OnGenerateNextValues() { base.OnGenerateNextValues(); XElement element = new XElement("Root", new XElement("Children1", 1), new XElement("Children6", 6) ); _RecordData = element; } } } XML Extensions File: <?xml version="1.0" encoding="utf-8" ?> <extensions assembly="" version="1" xmlns="urn:Microsoft.Data.Schema.Extensions" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:Microsoft.Data.Schema.Extensions Microsoft.Data.Schema.Extensions.xsd"> <extension type="CustomDataGenerators.RecordXMLDataGenerator" assembly="CustomDataGenerators, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" enabled="true"/> </extensions> Table.sql: CREATE TABLE [dbo].[Record] ( id int IDENTITY (1,1) NOT NULL, recordData xml NULL, userId int NULL, test nvarchar(max) NULL, rowver rowversion NULL, CONSTRAINT pk_RecordID PRIMARY KEY (id) )
