How to get label name in Autocad file using C# - c#

I think it is simple to do this but i dont know how to start? I want to get layer name or label name in the autocad file using c#. I search the forums but i really find anything valuable. I found the ObjectARX and AutoLisp, but i dont find any tutorial about theese API's. So, i want to simple example about the reach autocad file.

If you downloaded the ObjectARX SDK from the official site it contains many sample projects to get you started. You will need to have some AutoCAD knowledge to understand the structure of the .dwg database as exposed by the API. Be prepared to invest significant time in the project.
If you just are looking for a simple one time dump of the data in a .dwg file ask your local drafter as there is a command in the AutoCAD UI for doing this known as the Data Extraction Wizard.
Another answer on stackoverflow recommend this book chapter as a way to understand the AutoCAD database connection features.

It's simple as follows:
[CommandMethod("LayerIterator")]
public static void LayerIterator_Method()
{
Database database = HostApplicationServices.WorkingDatabase;
using (Transaction transaction = database.TransactionManager.StartTransaction())
{
SymbolTable symTable = (SymbolTable)transaction.GetObject(database.LayerTableId, OpenMode.ForRead);
foreach (ObjectId id in symTable)
{
LayerTableRecord symbol = (LayerTableRecord)transaction.GetObject(id, OpenMode.ForRead);
//TODO: Access to the symbol
MgdAcApplication.DocumentManager.MdiActiveDocument.Editor.WriteMessage(string.Format("\nName: {0}", symbol.Name));
}
transaction.Commit();
}
}

C# Windows Service > Render Web Page and Output to PDF

I am at a loss and could use some direction. I have a windows service that performs an Audit on customers. For new customers, I need to create a profile for each one. I already have a ASP.net C# web page that displays a single customer profile for the user:
http://webserver/showprofile.aspx?id=CustomerID
I would like to run some type of loop in the service that would render each new customer's profile and output all of those profiles into a PDF, Word Document, etc. Is there an easy way to do this using the existing Show Profile webpage?
If not, what is the best way to do this in C#? If it requires a component, I would prefer something free to very inexpensive. I currently have licenses for Telerik's complete line of tools if there is something there that can help. The bottom line, this has to be done programmatically as the user will have nothing to do with the generation/export to PDF. They will only access the resulting exported file.
Thanks in advance for your help.
You can use PdfCreator using the following command:
private PDFCreator.clsPDFCreator printer;
printer = new PDFCreator.clsPDFCreator();
printer.cDefaultPrinter = "PDFCreator";
printer.cOptions.UseAutosave = 0;
// Format in which file is to be saved. 0 if for pdf.
printer.cOptions.AutosaveFormat = 0;
printer.cClearCache();
printer.cStart();
foreach(int CustomerId in CustomerIDs)//array of customer ids as an example
{
printer.cPrintURL("http://webserver/showprofile.aspx?id=" + CustomerID.ToString());
}
You can download the software and necessary dll at the following link and look at the examples in the .net folder.

SharpSvn GetFileVersions revision range, only one file version returned

I'm trying to use SharpSvn to read the contents of two revisions of a file. When I run the following code the fileVersions collection only contains one item..
var svnClient = new SvnClient();
var revisionInfo = new SvnFileVersionsArgs
{
Start = 80092,
End = 80093
};
Collection<SvnFileVersionEventArgs> fileVersions;
svnClient.GetFileVersions(
new SvnUriTarget("https://DbDiff.svn.codeplex.com/svn/DbDiffCommon/DataAccess/SqlCommand11.xml"),
revisionInfo,
out fileVersions);
However I would expect it to include two items. Using TortoiseSVN I can see that the file changed in revision 80088, so I would expect to get this version when I use Start = 80092..
Using Start = 80091 doesn't help either..
The problem is not in your code but in the SvnBridge software used by codeplex. (They store the data in TFS and provide access via the bridge instead of using a real Subversion backend).
The bridge software doesn't implement this api properly. (I added an issue on it years ago, but as far as I can tell it was never fixed).
Subversion itself only uses this api for 'svn blame' (/praise/annotate), so I think the SvnBridge developers didn't care enough to fix this.
In AnkhSVN I detect the case of just receiving one file and then use SvnClient.Write() to obtain the file the slow way :(

read csv file with filehelpers error

I have an application developed in Visual Studio 2010 incorporating the CSLA.Net framework and FileHelpers Library.
I am using the code below to read a csv file with the file helpers library. I have break points set on every line and it faults after the engine.BeginReadFile. I have tried both csv and txt files on the read function. I even commented out the method i have and used the sample method from filehelpers along with their sample code and received the same error. The code will not progress beyond the engine.BeginReadFile method. It does not make it to the foreach loop at all. the error i receive is :
System.Exception._COMPlusExceptionCode -532462766
I am not very familiar with Visual Studio, but I cannot find any further breakdown of this error. the code in question is below.
using (FileHelperAsyncEngine engine = new FileHelperAsyncEngine(typeof(ProductionSchedule)))
{
// To Read Use
engine.BeginReadFile(filename);
foreach (ProductionSchedule prodsched in engine)
{
// get the connection string properly once a database is available
using (SqlConnection connection = new SqlConnection(Settings.Default.ConnectionString))
{
You are using the Async engine but you are not waiting for it to complete from the brief snippet you have given above.
Based on these assumptions, I would suspect that you are attempting to iterate through the collection as it's being changed. Either that or your SQL ConnectionString is invalid.

Free solution for automatic updates with a .NET/C# app?

From searching I can see this has been asked time and time again, but not adequately enough, so here goes. I'm a hobbyist developer with no budget. A program I've been developing has been in need of regular bugfixes, and me and users are getting tired of having to manually update.
Me, because my current solution of updating a text file through FTP and my download links on the website, and then hoping users will see the "there's an update message", and finally getting them to then be bothered to manually download the update, well quite frankly, is abysmal.
Users, because, well, "Are you ever going to implement auto-update?" "Will there ever be an auto-update feature?" And if I happen to screw up the update process, pitchforks start arriving.
Over the past I have looked into:
WinSparkle - No in-app updates, and the DLL is 500 KB. My current solution is a few KBs in the executable and has no in-app updates.
.NET Application Update Component - Unfortunately I can't comprehend the documentation.
Eduardo Olivera's AutoUpdate - This doesn't appear to support anything other than working with files that aren't in use.
wyUpdate - wyBuild isn't free, and while the wyUpdate specification is available, it's simply too complex and time-consuming to go through.
AppLife Update - Ditto the last sentence.
ClickOnce - Workarounds for implementing launching on startup are massive, horrendous and not worth it for such a simple feature. Publishing is a pain; manual FTP and replace of all files is required for servers without FrontPage Extensions.
It's quite disappointing that the situation on Windows is like this when you've got really nice and simple implementations for Mac OS X like Sparkle.
Implement it yourself! It will be fun. Create a separate application that only contains update logic i.e., fetch the files online, download them, replace local files, and show that visually to the user.
So your main application could check for updates, and if they exist it would prompt the user with the possibility to update. If the user wants to, it will run the update program, close itself (so the update can happen) and presto.
The only things you need are readily avaliable in C#, FTP access and IO.
Edit: I know it's not something terribly easy, but it's a perfect chance to learn:
How to (properly) download files, in an abstracted way that can be extended to ftp, http, etc.
How to (properly) do a simple task over many files - copying or overwriting them (this implies error handling).
Practice (because there's no "proper" way) to layer and encapsulate a piece of software.
How to deal with the OS/other software (antivirus/firewall/etc) not cooperating.
These are all things we all need to know well - If it takes some weeks to code an updater it means you were needing some weeks of learning. If you don't need to learn, time to hone your skills! If you don't know if you need, time to find out! :)
Note: I know I do need to learn better file and network I/O
Should've updated this ages ago, oops!
But anyway, I've been using SparkleDotNET for a while now and it's been working absolutely wonderfully. There's a few little bugs here and there but I've already helped get some of them squashed, and hopefully I'll be able to get rid of the others too :)
For those who have the time to run the publish functionality of Visual Studio, and whose app is relatively self-contained, and doesn't require anything like launching on startup, I'd recommend ClickOnce for sure. MetroTwit uses it and it's got a nice in-app updater interface, so it seems flexible (at least to a certain degree). For launching on startup, it's possible to do so, but methods to do so are quite hacky and don't work that well.
You can try Autoupdater.NET from GitHub I developed it my self and it works very well in my applications. You just have to add one line in your code and it's done. Also, it is open source so you can modify and use as you want.
You even can not to develop an external application but implement it as your application's module, e.g. into namespace Update, and use dynamic assembly builder to generate an exe, start it and exit app main, start it again when update will be finished.
Some more info.
There is also DDay update which is open source and is used by one of my customers. We/they are primarily interested in it in the context of a windows service at it works reasonably well for that.
For a more powerful solution, you may want to look at Google Omaha. It's what Chrome uses. You can get both in-app and automatic updates in the background when your application isn't running.
Try with MD5-Update it is absolutely free and easy no configuration need in your app only add library and publish the files.
https://github.com/jrz-soft-mx/MD5-Update/
1. Your need a web server with PHP for publish your files please include updt.exe.
2. Add index.php for make list of update files. aviable on github repository https://github.com/jrz-soft-mx/MD5-Update/blob/main/Tools/Tools.zip o create new app with this code.
<?php
$_dat = array();
$_dir=new RecursiveDirectoryIterator(".");
foreach (new RecursiveIteratorIterator($_dir) as $_itm) {
$_fil = str_replace(".".DIRECTORY_SEPARATOR, "", $_itm);
if(!is_dir($_fil) && $_fil != "index.php"){
$_dat[]=array('StrFil' => "$_fil", 'StrMd5' => strtoupper(md5_file($_fil)), 'lonSiz' => filesize($_fil));
}
}
echo json_encode($_dat, JSON_UNESCAPED_UNICODE);
?>
3. Add nuget repository at your proyect
PM> Install-Package MD5.Update
4. Call the library when your app stars, with your update folder url, update all files and download your new app on updt folder, for replace your app need updt.exe
string strUrl = "http://yourdomain.com/app/";
if (MD5Update.MD5Update.Check(strUrl, true))
{
Process.Start(AppDomain.CurrentDomain.BaseDirectory + #"updt.exe", AppDomain.CurrentDomain.FriendlyName + " " + Process.GetCurrentProcess().ProcessName);
Application.Exit();
}
5. updt.exe for replace the current app with the new app updt folder to app. aviable on github repository https://github.com/jrz-soft-mx/MD5-Update/blob/main/Tools/Tools.zip o create new app with this code.
try
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
List<string> lisArg = Environment.GetCommandLineArgs().ToList();
if (lisArg.Count < 2)
{
MessageBox.Show("Please provide App Excutable Name and Procees name");
Application.Exit();
return;
}
string strAppName = lisArg[1];
string strAppProcees = lisArg[2];
Process[] lisPro = Process.GetProcessesByName(strAppProcees);
foreach (Process Pro in lisPro)
{
if (Pro.Id != Process.GetCurrentProcess().Id)
{
Pro.Kill();
Thread.Sleep(1000);
}
}
string strAppMain = AppDomain.CurrentDomain.BaseDirectory + strAppName;
string strAppUpdate = AppDomain.CurrentDomain.BaseDirectory + #"updt\" + strAppName;
if (!File.Exists(strAppMain))
{
MessageBox.Show("App Excutable dosent exists");
Application.Exit();
return;
}
if (!File.Exists(strAppUpdate))
{
MessageBox.Show("App Excutable Updated dosent exists");
Application.Exit();
return;
}
File.Copy(strAppUpdate, strAppMain, true);
long fileSize = 0;
FileInfo currentFile = new FileInfo(strAppMain);
while (fileSize < currentFile.Length)
{
fileSize = currentFile.Length;
Thread.Sleep(1000);
currentFile.Refresh();
}
Process.Start(strAppMain);
}
catch (Exception Ex)
{
MessageBox.Show("An error ocurred");
File.WriteAllText(AppDomain.CurrentDomain.BaseDirectory + #"updt_" + DateTime.Now.ToString("yyyyMMddTHHmmss") + " .txt", Ex.ToString());
Application.Exit();
}
all guys are right specially look at the abatishchev reply.but i think some thing other need that guy forgot it. try to develop your project "modular".put them your code in class library as you can.so during the fix operation replace one of them.think a bout database fix.some time you need to add a column to your database table.what do you do for these cases?
a have developed an update project.in that , i have three kind of fixes.
1- BUG in program operation and need to replace a DDL file
2- Bug in program and need to update currently program executive file
3- bug or change the database and need to execute a sql server query
in a table on web host i put the version history and every time that my app start check for new version.if any update exist check for its type and download it and do the suitable action depend on the update kind and parameters
good luck dude

How to programatically do file versioning with SVN and .NET?

We have a report generator. Daily, it writes its data into a excel file.
For reasons of version controlling and file data safety, we need to alter this file, and commit the changes into a repository.
Do you recommend any .net SVN API you've used?
You should take a look at the SharpSvn .NET library. You will probably need checkout and commit commands:
Checking out:
string wcPath = "c:\\my working copy";
using (SvnClient client = new SvnClient())
{
client.CheckOut(new Uri("http://server/path/to/repos"), wcPath);
}
Committing:
string wcPath = "c:\\my working copy";
SvnCommitArgs a = new SvnCommitArgs();
a.LogMessage = "My log message";
using (SvnClient client = new SvnClient())
{
client.Commit(wcPath, a);
}
You might be able to turn on Autoversioning for your repository. Since it uses WebDAV, you can treat the repository just like a network drive (Web Folder). And you can treat the file as a normal file, just open, modify, and save.
If it were me , I would create a new repository for the excel data files. I don't think I'd like my code being autoversioned :)
We are using tool that actually searching for installed TortoiseSVN in predefined locations and using it command-line api. If that is for Windows and it's for not redistribution - it might be easier to do.
Helpful code for cmd:
#echo off
if exist "%ProgramW6432%\TortoiseSVN\bin\TortoiseProc.exe" set patht=%ProgramW6432%
if exist "%ProgramFiles%\TortoiseSVN\bin\TortoiseProc.exe" set patht=%ProgramFiles%
if exist "%ProgramFiles(x86)%\TortoiseSVN\bin\TortoiseProc.exe" set patht=%ProgramFiles(x86)%
echo Placing SVN Commit
"%patht%\TortoiseSVN\bin\TortoiseProc.exe" /command:commit /path:"%CD%" /notempfile
If you still want to do that task from code - SharpSVN http://sharpsvn.open.collab.net is better choiсe
The simplest would be to spawn a process and call SVN.exe
to commit your changes.
Here is a similiar question that was asked.
Does anyone know of a good C# API for Subversion?
Here is another resource
SVN Libraries for .NET?
