How to "programmatically" integrate diff tool with Visual Studio - c#

Is there a way to "programatically" integrate a diff tool (like WinDiff and WinMerge) with Visual Studio 2010? These files are not the files found at Solution Explorer.
The program would have to search and store in the List the files found from certain directory, and then compare the files with same names recursively.

As far as I can gather, you're looking for the TFS Difference class. Here's an example of how to use it:
string f1 = #"file1.cs";
string f2 = #"f2.cs";
Microsoft.TeamFoundation.VersionControl.Common.DiffOptions options = new Microsoft.TeamFoundation.VersionControl.Common.DiffOptions();
options.Recursive = true;
options.StreamWriter = new System.IO.StreamWriter(Console.OpenStandardOutput());
options.UseThirdPartyTool = true;
options.OutputType = Microsoft.TeamFoundation.VersionControl.Common.DiffOutputType.Unified;
var diff = Difference.DiffFiles(
f1, FileType.Detect(f1, null),
f2, FileType.Detect(f2, null),
options);
while (diff != null)
{
// Do whatever it is that you want to do here
diff = diff.Next;
}

Wix Bootstrapper - Best way to update/install Visual FoxPro database

As mentioned here wix-bootstrapper-update-ui-xaml-from-customaction I use a Bootstrapper to install two MSI-packages.
During the installation I want to install/update a Visual FoxPro database (consisting of free tables).
At the moment I achieve this by calling a Visual FoxPro-exe during the ApplyComplete-Event of the BootstrapperApplication. To establish a communication between the BootstrapperApplication and the Visual FoxPro-exe I use MSMQ :
private void OnApplyComplete(object sender, ApplyCompleteEventArgs e)
{
string updateFile = this.installationFolder + "\\updfile.exe";
if (!MessageQueue.Exists(NAMEDPVDATENBANKNACHRICHTENSCHLANGE))
{
this._msmq = MessageQueue.Create(UPDATEMSMQ);
}
else
{
this._msmq = new MessageQueue(UPDATEMSMQ);
}
this._msmq.SetPermissions("Everyone", MessageQueueAccessRights.FullControl);
this._msmq.Purge();
if (System.IO.File.Exists(updateFile))
{
this._dbUpdate = true;
ProcessStartInfo updateProcessInfo = new ProcessStartInfo();
updateProcessInfo.FileName = updateFile;
updateProcessInfo.Arguments = UPDATEMSMQ;
updateProcessInfo.UseShellExecute = true;
updateProcessInfo.WorkingDirectory = this.installationFolder;
updateProcessInfo.CreateNoWindow = true;
Process updateProcess = new Process();
updateProcess.StartInfo = updateProcessInfo;
updateProcess.EnableRaisingEvents = true;
updateProcess.Exited += new EventHandler(this.updateFinished);
updateProcess .Start();
while (this._dbUpdate)
{
Message msg = null;
try
{
nachricht = this._msmq.Receive(new TimeSpan(0, 0, 45));
}
catch (MessageQueueException msgEx)
{
if (nachrichtAusnahme.MessageQueueErrorCode != MessageQueueErrorCode.IOTimeout)
{
this.Engine.Log(LogLevel.Verbose, msgEx);
}
}
if (msg != null)
{
msg.Formatter = new ActiveXMessageFormatter();
this.Engine.Log(LogLevel.Verbose, "VfpUpdate - " + msg.Body.ToString());
}
}
}
this._msmq.Close();
MessageQueue.Delete(UPDATEMSMQ);
}
private void updateFinished(object sender, EventArgs e)
{
this._dbUpdate = false;
this.Engine.Log(LogLevel.Verbose, "Update finished");
}
This way it works like a charm unless there are errors during the the update of the Visual FoxPro database. It should be possible to roll-back the changes made during the installation. For me it would be no problem to create a backup of the Visual FoxPro-files and to restore the files if an error occurs. But how should I do this with the files changed by the actual Bootstrapper?
With a CustomAction I can use ActionResult.Failure or ActionResult.Success. But with a CustomAction I face the following issues:
no access to Application.Current (for reading values from a customized ResourceDictionary with localized strings that I use within the Bootstrapper)
MSMQ-queue is broken (closed?!) after the first message is delivered
display the currently performed task in the MainWindow.
Any advice on how to perform the update of the Visual FoxPro database inside a BootstrapperApplication is really welcome.
I don't know that in the context of an installation bootstrapper. OTOH, either a VFP database and tables or VFP tables (free) are just plain files that are copied/moved from a folder. You don't need to have an exe for that to create them programmatically.
Also having those files as part of the setup might not be a good idea as well. If some files are removed because of version changes then your installer might start to bark about that.
Looking at the bootstrapper code, I have a suspicion that you are creating those free tables in the installation folder or its subfolders which would be a real PITA. Because installation folder is generally under "Program Files (x86)" which is a read only location.
Your bootstrapper code is C#. You might use C# to create those tables as well. One way to do that is to use VFPOLEDB and ExecScript() calls.

Read and change project properties "Start external program" and "command line arguments"

I'm trying to read (and change) the project properties "Start external program" and "Command line arguments" of a VisualStudio 2013 project within a VSPackage. The code I wrote so far looks like:
var dte = GetService(typeof(DTE)) as DTE2;
if (dte == null)
return;
var sb = (SolutionBuild2)dte.Solution.SolutionBuild;
var projectNames = sb.StartupProjects as Array;
if (projectNames == null || projectNames.Length == 0)
return;
var project = dte.Solution.Item(projectNames.GetValue(0));
var config = project.ConfigurationManager.ActiveConfiguration;
But I can't find the two spcific properties neither in the project nor in the config.
The EnvDTE.Configuration class has a Properties collection that has your desired values:
config.Properties.Item("StartProgram").Value
config.Properties.Item("StartArguments").Value
FWIW, the VSLangProj.dll assembly has a VSLangProj.ProjectConfigurationProperties class with the property names that you can expect in the config.Properties collection.

Copying/over-writing one source to another in TFS?

Question Background:
Within my TF Server I have two folders, one is a simple 'HelloWorld.sln' in a folder called 'HelloWorldDev' and the other is a 'HelloWorld.sln' in a folder called 'HelloWorldQA'. Each folder contains its respective .cs files etc.
I want to checkout a file from the HelloWorld QA folder, replace - or update it - with a version from the HelloWorldDev folder with the same file name, then check this file back into the HelloWorldQA folder with the relevant changes.
Question:
I am very new to the TFS API so I'm not 100% if what I'm trying to ask is the correct way to proceed, or if its even possible. Can someone give me an example of achieving this?
Code so far:
string fileName = #"C:\Users\Me\Documents\TfsServer\HelloWorldQA\IHelloWorld.cs";
string fileNameQA = #"C:\Users\Me\Documents\TfsServer\HelloWorld\IHelloWorld.cs";
string uri = #"https://tfsServer.visualstudio.com/";
var workspaceInfo = Workstation.Current.GetLocalWorkspaceInfo(fileName);
var server = new TfsTeamProjectCollection(workspaceInfo.ServerUri);
var workspace = workspaceInfo.GetWorkspace(server);
workspace.PendEdit(fileName);
FileInfo fi = new FileInfo(fileName);
var workspaceInfoQA = Workstation.Current.GetLocalWorkspaceInfo(fileNameQA);
var serverQA = new TfsTeamProjectCollection(workspaceInfo.ServerUri);
var workspaceQA = workspaceInfo.GetWorkspace(serverQA);
workspace.PendEdit(fileNameQA);
FileInfo fiQA = new FileInfo(fileNameQA);
First, instead of using 2 workspaces, you can simply map both folders in the same workspace.
Then you're looking for a merge operation:
var sourcePath = workspace.GetServerItemForLocalItem(fileName);
var targetPath = workspace.GetServerItemForLocalItem(fileNameQA);
var getStatus = workspace.Merge(sourcePath, targetPath, null, null);
if (getStatus.NumUpdated > 0)
{
//OK
}

C# Windows Application - Linking a button to start a game

I believe I have been taking the right approach to this so far, but I would like to have a button start a video game on my computer.
So far, I have a button linking to a process:
void button2_Click(object sender, EventArgs e)
{
process1.Start();
}
this.process1.EnableRaisingEvents = true;
this.process1.StartInfo.Domain = "";
this.process1.StartInfo.FileName = "MBO\\marbleblast.exe";
this.process1.StartInfo.LoadUserProfile = false;
this.process1.StartInfo.Password = null;
this.process1.StartInfo.StandardErrorEncoding = null;
this.process1.StartInfo.StandardOutputEncoding = null;
this.process1.StartInfo.UserName = "";
this.process1.SynchronizingObject = this;
this.process1.Exited += new System.EventHandler(this.Process1Exited);
So, where-ever I place the EXE (the one I'm coding), it will launch the "marbleblast.exe" under the subfolder MBO relative to it's location.
It seems to be working and trying to launch the game, however, it says it cannot load files that are there. I tested the game without my launcher, and it worked. I believe it's trying to run the EXE, but not letting it use the other files inside of it's folder.
I'll give more details if needed.
How can I get the game to run normally?
try adding this
this.process1.StartInfo.WorkingDirectory= "MBO\\";
or something similar to set the Working Directory.
this.process1.StartInfo.WorkingDirectory= "MBO\";
There's sloppy programming in the game, it relies on the Environment.CurrentDirectory being set right. Which by default is the same directory as where the EXE is located. The upvoted answer repeats the mistake though. To make that statement actually fix the problem, you now rely on your CurrentDirectory being set right. If it is not set where you think it is then it still won't work.
The problem with the program's current directory is that it can be changed by software that you don't control. The classic example is OpenFileDialog with the RestoreDirectory property set to the default value of false. Etcetera.
Always program defensively and pass the full path name of files and directories. Like c:\mumble\foo.ext. To get that going, start with Assembly.GetEntryAssembly().Location, that's the path to your EXE. Then use the System.IO.Path class to generate path names from that. The correct always-works code is:
using System.IO;
using System.Reflection;
...
string myDir = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
string gameDir = Path.Combine(myDir, "MBO");
string gameExe = Path.Combine(gameDir, "marbleblast.exe");
process1.StartInfo.FileName = gameExe;
process1.StartInfo.WorkingDirectory = gameDir;
process1.SynchronizingObject = this;
process1.EnableRaisingEvents = true;
process1.Exited += new EventHandler(Process1Exited);
Set the WorkingDirectory property of the ProcessInfo to the correct directory.
I am Dobrakmato from MBForums. You simple need to add Working directory for Marble Blast.
this.process1.EnableRaisingEvents = true;
this.process1.StartInfo.Domain = "";
this.process1.StartInfo.FileName = "MBO\\marbleblast.exe";
this.process1.StartInfo.WorkingDirectory = "pathto marbleblast.exe directory";
this.process1.StartInfo.LoadUserProfile = false;
this.process1.StartInfo.Password = null;
this.process1.StartInfo.StandardErrorEncoding = null;
this.process1.StartInfo.StandardOutputEncoding = null;
this.process1.StartInfo.UserName = "";
this.process1.SynchronizingObject = this;
this.process1.Exited += new System.EventHandler(this.Process1Exited);

Folder of recovered files missing their names - How can I find the one I am looking for by the contents of the file?

I managed to accidentally delete a backup of files I had which I then later recovered. The recovery has lost the files names and location and I am left with about 3000+ .indd (Adobeb InDesign) files.
My problem is I am trying to find the .indd file that I was working on with out having to open each one manually to check.
I know some of the words that I had and I am wondering if I could maybe read the .indd file using a binary reader looking for one of the keywords...I could build it in c# or whatever
Anyone got any ideas?
If regular search does not work, try the built in scripting, of which you can use Javascript, Visual Basic Script, or AppleScript to code. I'm going with JS...
I'm no expert, but I found this code snippet from page 101 of InDesignCS5_ScriptingGuide_JS.pdf and modified it a bit:
var folder = new Folder("C:/Path/To/Files");
var files = folder.getFiles('*.indd');
for (var i=0; i<files.length; i++) {
var file = files[i];
open(file):
var myDocument = app.activeDocument;
//Clear the find/change text preferences.
app.findTextPreferences = NothingEnum.nothing;
app.changeTextPreferences = NothingEnum.nothing;
//Search the document for the string "Important Text".
app.findTextPreferences.findWhat = "Important Text";
//Set the find options.
app.findChangeTextOptions.caseSensitive = false;
app.findChangeTextOptions.includeFootnotes = true;
app.findChangeTextOptions.includeHiddenLayers = true;
app.findChangeTextOptions.includeLockedLayersForFind = true;
app.findChangeTextOptions.includeLockedStoriesForFind = true;
app.findChangeTextOptions.includeMasterPages = true;
app.findChangeTextOptions.wholeWord = false;
//Perform search
var myFoundItems = myDocument.findText();
if (myFoundItems.length) {
alert("FOUND!");
break;
}
app.findTextPreferences = NothingEnum.nothing;
app.changeTextPreferences = NothingEnum.nothing;
myDocument.close();
}
Don't quote me on that, I did not actually run the code, but that's the idea.
