Programmatically Import Block Into AutoCAD (C#)

I'm writing a plugin for AutoCAD and want to import all the blocks it will use at the beginning to make sure that they are available when needed. To do that, I use this method
public static void ImportBlocks(string[] filesToTryToImport, string filter = "")
{
foreach (string blockToImport in filesToTryToImport)
{
if (blockToImport.Contains(filter))
{
Database sourceDb = new Database(false, true); //Temporary database to hold data for block we want to import
try
{
sourceDb.ReadDwgFile(blockToImport, System.IO.FileShare.Read, true, ""); //Read the DWG into a side database
ObjectIdCollection blockIds = new ObjectIdCollection(); // Create a variable to store the list of block identifiers
Autodesk.AutoCAD.DatabaseServices.TransactionManager tm = sourceDb.TransactionManager;
using (Transaction myT = tm.StartTransaction())
{
// Open the block table
BlockTable bt = (BlockTable)tm.GetObject(sourceDb.BlockTableId, OpenMode.ForRead, false);
// Check each block in the block table
foreach (ObjectId btrId in bt)
{
BlockTableRecord btr = (BlockTableRecord)tm.GetObject(btrId, OpenMode.ForRead, false);
// Only add named & non-layout blocks to the copy list
if (!btr.IsAnonymous && !btr.IsLayout)
{
blockIds.Add(btrId);
}
btr.Dispose();
}
}
// Copy blocks from source to destination database
IdMapping mapping = new IdMapping();
sourceDb.WblockCloneObjects(blockIds, _database.BlockTableId, mapping, DuplicateRecordCloning.Replace, false);
_editor.WriteMessage("\nCopied " + blockIds.Count.ToString() + " block definitions from " + blockToImport + " to the current drawing.");
}
catch (Autodesk.AutoCAD.Runtime.Exception ex)
{
_editor.WriteMessage("\nError during copy: " + ex.Message);
}
finally
{
sourceDb.Dispose();
}
}
}
}
That method appears to work because it successfully executes. However when I go to insert a block in the drawing via AutoCAD's interface it doesn't show up as an option and when I try to insert it programmatically it throws a FileNotFound exception meaning it didn't work. What's wrong with this method? Thanks in advance!
EDIT: Here is a less complicated method with a test method
public static void ImportSingleBlock(string fileToTryToImport)
{
using (Transaction tr = _database.TransactionManager.StartTransaction())
{
Database sourceDb = new Database(false, true); //Temporary database to hold data for block we want to import
try
{
sourceDb.ReadDwgFile(fileToTryToImport, System.IO.FileShare.Read, true, ""); //Read the DWG into a side database
_database.Insert(fileToTryToImport, sourceDb, false);
_editor.WriteMessage("\nSUCCESS: " + fileToTryToImport);
}
catch (Autodesk.AutoCAD.Runtime.Exception ex)
{
_editor.WriteMessage("\nERROR: " + fileToTryToImport);
}
finally
{
sourceDb.Dispose();
}
tr.Commit();
}
}
[CommandMethod("TESTSINGLEBLOCKIMPORTING")]
public void TestSingleBlockImporting()
{
OpenFileDialog ofd = new OpenFileDialog();
DialogResult result = ofd.ShowDialog();
if (result == DialogResult.Cancel) //Ending method on cancel
{
return;
}
string fileToTryToImport = ofd.FileName;
using (Transaction tr = _database.TransactionManager.StartTransaction())
{
EntityMethods.ImportSingleBlock(fileToTryToImport);
tr.Commit();
}
}
This file is the block I'm trying to import. Hope this inspires someone cause I am desperately lost right now.

Your code is correct and should work. In fact I did tried it and works fine. You're probably missing to Commit() a outer transaction (where you call this ImportBlocs() method). Check:
using (Transaction trans = _database.TransactionManager.StartTransaction())
{
ImportBlocks(... parameters here ...);
trans.Commit(); // remember to call this commit, if omitted, Abort() is assumed
}

I had the same issue, very similar code. Issue was that
_database.Insert(fileToTryToImport, sourceDb, false);
should be
_database.Insert(blockName, sourceDb, false);
You can see that the first parameter has to be "blockName", and not the file path.

ASP.NET Crystal Report change "Set Datasource Location" is not working

I am trying to setup a test platform for a Live application upgrade. In order not to mess up my Live data, I duplicated the database to another database. And update my CR using "Set Datasource Location" and point to the new DB. However, they are still loading records from the live DB! FYI I am connecting using ODBC and I have created a test ODBC for the test platform.
Previously my DC is "osso_odbc", but I have updated it to "ossotest", but it is still loading record from "osso_odbc".
Anybody know what went wrong and what I should do?
Thanks.

In the end what I did is remove all the existing connection and re-create all the form elements. Now it is working.

1 - If "save data in the report" is checked, old data can still be prompt
2 - If you have subreports you must "set datasource location" for subreports, too
3 - "Set datasource Location" is not sointuitive, did you use righr procedure
4 - We are talking about changing datasource in design time, not in asp.net runitme, are we?
I use the following code to programmatically change connection, based on a connectionsting and to pass parameters to the report, based on Querystring.
bool Logon(ReportDocument cr, string server, string db, bool integratedSecurity, string id, string pass)
{
ConnectionInfo ci = new ConnectionInfo();
SubreportObject subObj;
ci.ServerName = server;
ci.DatabaseName = db;
if (integratedSecurity)
ci.IntegratedSecurity = true;
else
{
ci.IntegratedSecurity = false;
ci.UserID = id;
ci.Password = pass;
}
PassParameters();
if (!ApplyLogon(cr, ci))
return false;
for (int i = 0; i < cr.ReportDefinition.ReportObjects.Count; i++)
if (cr.ReportDefinition.ReportObjects[i].Kind == ReportObjectKind.SubreportObject)
{
subObj = (SubreportObject)cr.ReportDefinition.ReportObjects[i];
if (!ApplyLogon(cr.OpenSubreport(subObj.SubreportName), ci))
return false;
}
return true;
}
bool ApplyLogon(ReportDocument cr, ConnectionInfo ci)
{
TableLogOnInfo li;
// for each table apply connection info
for (int i = 0; i < cr.Database.Tables.Count; i++)
{
li = cr.Database.Tables[i].LogOnInfo;
li.ConnectionInfo = ci;
cr.Database.Tables[i].ApplyLogOnInfo(li);
// check if logon was successful
// if TestConnectivity returns false, check
// logon credentials
if (TestConnectivity(cr, i))
{
// drop fully qualified table location
if (cr.Database.Tables[i].Location.IndexOf(".") > 0)
cr.Database.Tables[i].Location = cr.Database.Tables[i].Location.Substring(cr.Database.Tables[i].Location.LastIndexOf(".") + 1);
cr.Database.Tables[i].Location.Substring(cr.Database.Tables[i].Location.LastIndexOf(".") + 1);
}
else return false;
}
return true;
}
private static bool TestConnectivity(ReportDocument cr, int i)
{
bool test = false;
try { test = cr.Database.Tables[i].TestConnectivity(); }
catch (System.Runtime.InteropServices.COMException)
{
try { test = cr.Database.Tables[i].TestConnectivity(); }
catch (System.Runtime.InteropServices.COMException)
{
try { test = cr.Database.Tables[i].TestConnectivity(); }

Salesforce SOAP create record

I have the following code to insert a record (I will be inserting 1000's). I get a successful insert but all of the numeric fields are EMPTY in salesforce. The one text field works fine ("Church of Randy") and appears in salesforce. Any ideas what I could be doing wrong?
public void InsertTestRecord()
{
ChurchHist__c ch = new ChurchHist__c();
ch.ChurchId__c = 9999;
ch.ChurchName__c = "Church of Randy";
ch.ReportYear__c = 2013;
ch.ReportMonth__c = 08;
ch.RegisteredMembers__c = 777;
ch.ActiveMembers__c = 111;
ch.InactiveMembers__c = 666;
ch.UsersForMonth__c = 25;
ch.ContribForMonth__c = 789.01;
ch.ContribYTD__c = 200000.02;
ch.AchContrib__c = 200000.00;
ch.CcContrib__c = 0.02;
ch.AchToCc__c = 0.12345;
sObject[] s = new sObject[1];
s[0] = ch;
try
{
SaveResult[] saveResult = binding.create(s);
if (saveResult[0].success)
{
Debug.Print("Success");
}
else
{
foreach (Error error in saveResult[0].errors)
{
Debug.Print(error.statusCode.ToString());
Debug.Print(error.message);
}
}
}
catch (SoapException se)
{
Debug.Print(se.ToString());
}
}

You need to set the specified flags, e.g. numeric property has an associated specified flag that controls if the .NET soap engine will actually send that property over the wire, unfortuantly the setter for the property does not automatically set the specified flag. e.g.
ch.ChurchId__c = 9999;
ch.ChurchId__cSpecified = true;
ch.reportyear__c = 2013;
ch.reportyear__cSpecified = true;
The specified flags are a "feature" of the .NET soap system for certain types. (numbers & dates IIRC).

SQLite connection strategies

I have a database that may be on the network drive.
There are two things that I want to achieve:
When the first user connects to it in read-only mode (he doesn't
have a read-write access to the location, or the database is
read-only), other users must use the read-only connection also (even
if they have RW access).
When the first user connects to it in RW mode, others can not
connect to the database at all.
I'm using SQLite, and the concurrency should not be the problem, as the database should never be used by more than 10 people at the same time.
UPDATE: This is a sample that I'm trying to make work, so I could implement it in the program itself. Almost everything can be changed.
UPDATE: Now when I finally understood what #CL. was telling me, I made it work and this is the updated code.

Set PRAGMA locking_mode=EXCLUSIVE to prevent SQLite from releasing its locks after a transaction ends.

I don't know if it can be done within db but in application;
You can set a global variable (not sure if it's a web or desktop app) to check if anyone connected and he has a write access or not.
After that you can check the other client's state.

Database backup via SMO (SQL Server Management Objects) in C#

I need to backup database (using SQL Server 2008 R2). Size of db is about 100 GB so I want backup content only of important tables (containing settings) and of course object of all tables, views, triggers etc.
For example:
db: Products
tables: Food, Clothes, Cars
There is too much cars in Cars, so I will only backup table definition (CREATE TABLE ...) and complete Food and Clothes (including its content).
Advise me the best solution, please. I will probably use SMO (if no better solution). Should I use Backup class? Or Scripter class? Or another (if there is any)? Which class can handle my requirements?
I want backup these files to *.sql files, one per table if possible.
I would appreciate code sample. Written in answer or somewhere (post url), but be sure that external article has solution exactly for this kind of problem.
You can use this part of code
ServerConnection connection = new ServerConnection("SERVER,1234", "User", "User1234");
Server server = new Server(connection);
Database database = server.Databases["DbToBackup"];

Using SMO. You will have to play with the options you need.
StringBuilder sb = new StringBuilder();
using (SqlConnection connection = new SqlConnection("connectionString")) {
ServerConnection serverConnection = new ServerConnection(connection);
Server server = new Server(serverConnection);
Database database = server.Databases["databaseName"];
Scripter scripter = new Scripter(server);
scripter.Options.ScriptDrops = false;
scripter.Options.WithDependencies = true;
scripter.Options.ScriptData = true;
Urn[] smoObjects = new Urn[1];
foreach (Table table in database.Tables) {
smoObjects[0] = table.Urn;
if (!table.IsSystemObject) {
foreach (string s in scripter.EnumScript(smoObjects)) {
System.Diagnostics.Debug.WriteLine(s);
sb.AppendLine(s);
}
}
}
}
// Write to *.sql file on disk
File.WriteAllText(#".\backup.sql");
Another easy way to do this is by backing the database to xml files. To do this use a DataTable and call WriteXml and WriteXmlSchema. (You need the schema later on so it can be imported/restored using the same method). This method means you are backing up per table.
private bool BackupTable(string connectionString, string tableName, string directory) {
using (SqlConnection connection = new SqlConnection(connectionString)) {
try {
connection.Open();
}
catch (System.Data.SqlClient.SqlException ex) {
// Handle
return false;
}
using (SqlDataAdapter adapter = new SqlDataAdapter(string.Format("SELECT * FROM {0}", tableName), connection)) {
using (DataTable table = new DataTable(tableName)) {
adapter.Fill(table);
try {
table.WriteXml(Path.Combine(directory, string.Format("{0}.xml", tableName)));
table.WriteXmlSchema(Path.Combine(directory, string.Format("{0}.xsd", tableName)));
}
catch (System.UnauthorizedAccessException ex) {
// Handle
return false;
}
}
}
}
return true;
}
You can later on then push these back into a database us by using ReadXmlSchema and ReadXml, using an adapter to fill and update the table to the database. I assume you are knowledgable in basic CRUD so I shouldn't need to cover that part.
If you want to use SMO, here is a Msdn article on using the Backup and Restore classes to backup and restore a database. The code sample us unformatted, and in VB.NET, but easily translatable.
http://msdn.microsoft.com/en-us/library/ms162133(v=SQL.100).aspx
Lastly, which may be easier, talk to the IT guys and see if they will let you remote in or give you access to do the backup yourself. If you are writing the software and this is a crucial step, speak up and let them know how important it is for you to do this, as this will reduce cost in you having to write a custom tool when great tools already exist. Especially since the database is 100GB, you can use the tools you know already work.

This arcitle was enough informative to solve my problem. Here is my working solution.
I decided script all objects to one file, it's better solution because of dependencies, I think. If there is one table per on file and there is also some dependencies (foreign keys for example) it would script more code than if everything is in one file.
I omitted some parts of code in this sample, like backuping backup files in case wrong database backup. If there is no such a system, all backups will script to one file and it will go messy
