  • Can review changes in Acrobat Reader (Pro, or not) be 'applied' to a PDF?

    - by Danjah
    Hi there, As part of an enhancement to my workplace processes, we're trying to streamline review of various documents. Yeah, there's way better alternatives to what I'm about to suggest, but the reality is that I have no time allocated to investigate things like DAV, repo setups and such. What I do have time allocated for is improving workflow around tools we already use. So I tried to work through the Adobe PDF collaborative review cycle. I have to say it was pretty amazing, from the notify toolbar icon to doc merging, to user access control. They offer it all, EXCEPT the ability to actually apply review changes to a PDF!?! To clarify, after sending a PDF through the collab review cycle (involving a bunch for external editors and internal staff) the end result was a PDF full of rich feedback - but I can see no way to finalised and apply those 'accepted' review points to the PDF in question. I hope this is clear enough, feel free to ask questions to clarify - perhaps I'm just missing something obvious, but perhaps applying changes to an already existing PDF is not possible? -d

  • is there a way to designate the line token delimiter in Perl's file reader?

    - by Dr.Dredel
    I'm reading a text file via CGI in, in perl, and noticing that when the file is saved in mac's textEdit the line separator is recognized, but when I upload a CSV that is exported straight from excel, they are not. I'm guessing it's a \n vs. \r issue, but it got me thinking that I don't know how to specify what I would like the line terminator token to be, if I didn't want the one it's looking for by default.

  • Windows 2008 server smart card security module problem

    - by chris13work
    Hi, I've got a smart card reader and a server application using it as a security module. If I run it under DOS prompt, everything is fine. The server is running and clients can connect to it. I tried to install the server as window service and start it. The server starts but always gives back authentication error because it cannot call the smart card to do encryption. Then I tried to start it with task scheduler and set the trigger factor as "on startup". The server starts also but still cannot access the smart card reader. Then I tried remote desktop to the machine and run the server application under DOS prompt. Same error is returned. The situation is that the smart card reader only works under active console desktop environment. In the server application, WINSCARD API is used to access the smart card reader. Any suggestion so that we can access the smart card reader in running services? OS: Windows Server 2008 Smart Card Driver: Windows USB smart card Reader Smart Card API: WINSCARD

  • Is there a free PDF printer / distiller that creates signable documents?

    - by Coderer
    I've used various methods (mentioned elsewhere on this site) to create PDFs, using a printer driver or converting from PostScript, etc. The common problem is that if I open any of the output files in the newer versions of Adobe Reader, there's an option to "Place Signature" but it's greyed out, or gives an error message that the feature has been disabled for this document. As far as I can tell, there's an option set somewhere in the document metadata that tells Reader "allow the user to sign this document", or don't. None of the free/open source tools that have been been linked to in other SU posts have had this listed as an option (though to be fair I haven't actually downloaded and tried all of them). Is there a tool that does this? Can I just poke a bit with a hex editor somewhere to turn on this functionality? I can sometimes get access to Acrobat Professional to turn on this option, but doing it for every desired case would be more work than I care to do. The current workaround for single-page documents is: Print the document to PDF (possibly via postscript) Open a single-page blank PDF with the "signable" bit turned on in Reader create a custom "stamp" using the Reader markup tools, by importing the printed-to document "stamp" an image of the printed document on the blank page, hoping to get it centered about right place a signature over the document-but-not-really you just stamped This obviously does not scale well at all. It would be much better if I could: Print the document to PDF Drag the document to a simple shortcut / tool / whatever Open the document in Reader Place a signature in the document ETA: Sorry, maybe I should have been clearer -- I'm talking about the certificate-based digital signing available in Adobe Reader, not adding a virtual ink signature. Also, any solution really would have to be available offline.

  • MemoryStream, XmlTextWriter and Warning 4 CA2202 : Microsoft.Usage

    - by rasx
    The Run Code Analysis command in Visual Studio 2010 Ultimate returns a warning when seeing a certain pattern with MemoryStream and XmlTextWriter. This is the warning: Warning 7 CA2202 : Microsoft.Usage : Object 'ms' can be disposed more than once in method 'KinteWritePages.GetXPathDocument(DbConnection)'. To avoid generating a System.ObjectDisposedException you should not call Dispose more than one time on an object.: Lines: 421 C:\Visual Studio 2010\Projects\Songhay.DataAccess.KinteWritePages\KinteWritePages.cs 421 Songhay.DataAccess.KinteWritePages This is the form: static XPathDocument GetXPathDocument(DbConnection connection) { XPathDocument xpDoc = null; var ms = new MemoryStream(); try { using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { writer.WriteStartDocument(); writer.WriteStartElement("data"); do { while(reader.Read()) { writer.WriteStartElement("item"); for(int i = 0; i < reader.FieldCount; i++) { writer.WriteRaw(String.Format("<{0}>{1}</{0}>", reader.GetName(i), reader[i].ToString())); } writer.WriteFullEndElement(); } } while(reader.NextResult()); writer.WriteFullEndElement(); writer.WriteEndDocument(); writer.Flush(); ms.Position = 0; xpDoc = new XPathDocument(ms); } } } finally { ms.Dispose(); } return xpDoc; } The same kind of warning is produced for this form: XPathDocument xpDoc = null; using(var ms = new MemoryStream()) { using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { //... } } } return xpDoc; By the way, the following form produces another warning: XPathDocument xpDoc = null; var ms = new MemoryStream(); using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { //... } } return xpDoc; The above produces the warning: Warning 7 CA2000 : Microsoft.Reliability : In method 'KinteWritePages.GetXPathDocument(DbConnection)', object 'ms' is not disposed along all exception paths. Call System.IDisposable.Dispose on object 'ms' before all references to it are out of scope. C:\Visual Studio 2010\Projects\Songhay.DataAccess.KinteWritePages\KinteWritePages.cs 383 Songhay.DataAccess.KinteWritePages In addition to the following, what are my options?: Supress warning CA2202. Supress warning CA2000 and hope that Microsoft is disposing of MemoryStream (because Reflector is not showing me the source code). Rewrite my legacy code to recognize the wonderful XDocument and LINQ to XML.

  • SQL DataReader how to show null-values from query

    - by cc0
    I have a DataReader and a StringBuilder (C#.NET) used in the following way; while (reader.Read()) { sb.AppendFormat("{0},{1},{2},",reader["Col1"], reader["Col2"], reader["Col3"]); } Which works great for my use, but when a row is null I need it to return "null", instead of just "". What would be a good way of accomplishing that? Suggestions are very appreciated

  • building list of child objects inside main object

    - by Asdfg
    I have two tables like this: Category: Id Name ------------------ 1 Cat1 2 Cat2 Feature: Id Name CategoryId -------------------------------- 1 F1 1 2 F2 1 3 F3 2 4 F4 2 5 F5 2 In my .Net classes, i have two POCO classes like this: public class Category { public int Id {get;set;} public int Name {get;set;} public IList<Feature> Features {get;set;} } public class Feature { public int Id {get;set;} public int CategoryId {get;set;} public int Name {get;set;} } I am using a stored proc that returns me a result set by joining these 2 tables. This is how my Stored Proc returns the result set. SELECT c.CategoryId, c.Name Category, f.FeatureId, f.Name Feature FROM Category c INNER JOIN Feature f ON c.CategoryId = f.CategoryId ORDER BY c.Name --Resultset produced by the above query CategoryId CategoryName FeatureId FeatureName --------------------------------------------------- 1 Cat1 1 F1 1 Cat1 2 F2 2 Cat2 3 F3 2 Cat2 4 F4 2 Cat2 5 F5 Now if i want to build the list of categories in my .Net code, i have to loop thru the result set and add features unless the category changes. This is how my .Net code looks like that builds Categories and Features. List<Category> categories = new List<Category>(); Int32 lastCategoryId = 0; Category c = new Category(); using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { //Check if the categoryid is same as previous one. //If Not, add new category. //If Yes, dont add the category. if (lastCategoryId != Convert.ToInt32(reader["CategoryId"])) { c = new Category { Id = Convert.ToInt32(reader["CategoryId"]), Name = reader["CategoryName"].ToString() }; c.Features = new List<Feature>(); categories.Add(c); } lastCategoryId = Convert.ToInt32(reader["CategoryId"]); //Add Feature c.Features.Add(new Feature { Name = reader["FeatureName"].ToString(), Id = Convert.ToInt32(reader["FeatureId"]) }); } return categories; } I was wondering if there is a better way to do build the list of Categories?

  • Feedback on Optimizing C# NET Code Block

    - by Brett Powell
    I just spent quite a few hours reading up on TCP servers and my desired protocol I was trying to implement, and finally got everything working great. I noticed the code looks like absolute bollocks (is the the correct usage? Im not a brit) and would like some feedback on optimizing it, mostly for reuse and readability. The packet formats are always int, int, int, string, string. try { BinaryReader reader = new BinaryReader(clientStream); int packetsize = reader.ReadInt32(); int requestid = reader.ReadInt32(); int serverdata = reader.ReadInt32(); Console.WriteLine("Packet Size: {0} RequestID: {1} ServerData: {2}", packetsize, requestid, serverdata); List<byte> str = new List<byte>(); byte nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // Password Sent to be Authenticated string string1 = Encoding.UTF8.GetString(str.ToArray()); str.Clear(); nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // NULL string string string2 = Encoding.UTF8.GetString(str.ToArray()); Console.WriteLine("String1: {0} String2: {1}", string1, string2); // Reply to Authentication Request MemoryStream stream = new MemoryStream(); BinaryWriter writer = new BinaryWriter(stream); writer.Write((int)(1)); // Packet Size writer.Write((int)(requestid)); // Mirror RequestID if Authenticated, -1 if Failed byte[] buffer = stream.ToArray(); clientStream.Write(buffer, 0, buffer.Length); clientStream.Flush(); } I am going to be dealing with other packet types as well that are formatted the same (int/int/int/str/str), but different values. I could probably create a packet class, but this is a bit outside my scope of knowledge for how to apply it to this scenario. If it makes any difference, this is the Protocol I am implementing. http://developer.valvesoftware.com/wiki/Source_RCON_Protocol

  • Troubleshooting Application Timeouts in SQL Server

    - by Tara Kizer
    I recently received the following email from a blog reader: "We are having an OLTP database instance, using SQL Server 2005 with little to moderate traffic (10-20 requests/min). There are also bulk imports that occur at regular intervals in this DB and the import duration ranges between 10secs to 1 min, depending on the data size. Intermittently (2-3 times in a week), we face an issue, where queries get timed out (default of 30 secs set in application). On analyzing, we found two stored procedures, having queries with multiple table joins inside them of taking a long time (5-10 mins) in getting executed, when ideally the execution duration ranges between 5-10 secs. Execution plan of the same displayed Clustered Index Scan happening instead of Clustered Index Seek. All required Indexes are found to be present and Index fragmentation is also minimal as we Rebuild Indexes regularly alongwith Updating Statistics. With no other alternate options occuring to us, we restarted SQL server and thereafter the performance was back on track. But sometimes it was still giving timeout errors for some hits and so we also restarted IIS and that stopped the problem as of now." Rather than respond directly to the blog reader, I thought it would be more interesting to share my thoughts on this issue in a blog. There are a few things that I can think of that could cause abnormal timeouts: Blocking Bad plan in cache Outdated statistics Hardware bottleneck To determine if blocking is the issue, we can easily run sp_who/sp_who2 or a query directly on sysprocesses (select * from master..sysprocesses where blocking <> 0).  If blocking is present and consistent, then you'll need to determine whether or not to kill the parent blocking process.  Killing a process will cause the transaction to rollback, so you need to proceed with caution.  Killing the parent blocking process is only a temporary solution, so you'll need to do more thorough analysis to figure out why the blocking was present.  You should look into missing indexes and perhaps consider changing the database's isolation level to READ_COMMITTED_SNAPSHOT. The blog reader mentions that the execution plan shows a clustered index scan when a clustered index seek is normal for the stored procedure.  A clustered index scan might have been chosen either because that is what is in cache already or because of out of date statistics.  The blog reader mentions that bulk imports occur at regular intervals, so outdated statistics is definitely something that could cause this issue.  The blog reader may need to update statistics after imports are done if the imports are changing a lot of data (greater than 10%).  If the statistics are good, then the query optimizer might have chosen to scan rather than seek in a previous execution because the scan was determined to be less costly due to the value of an input parameter.  If this parameter value is rare, then its execution plan in cache is what we call a bad plan.  You want the best plan in cache for the most frequent parameter values.  If a bad plan is a recurring problem on your system, then you should consider rewriting the stored procedure.  You might want to break up the code into multiple stored procedures so that each can have a different execution plan in cache. To remove a bad plan from cache, you can recompile the stored procedure.  An alternative method is to run DBCC FREEPROCACHE which drops the procedure cache.  It is better to recompile stored procedures rather than dropping the procedure cache as dropping the procedure cache affects all plans in cache rather than just the ones that were bad, so there will be a temporary performance penalty until the plans are loaded into cache again. To determine if there is a hardware bottleneck occurring such as slow I/O or high CPU utilization, you will need to run Performance Monitor on the database server.  Hopefully you already have a baseline of the server so you know what is normal and what is not.  Be on the lookout for I/O requests taking longer than 12 milliseconds and CPU utilization over 90%.  The servers that I support typically are under 30% CPU utilization, but your baseline could be higher and be within a normal range. If restarting the SQL Server service fixes the problem, then the problem was most likely due to blocking or a bad plan in the procedure cache.  Rather than restarting the SQL Server service, which causes downtime, the blog reader should instead analyze the above mentioned things.  Proceed with caution when restarting the SQL Server service as all transactions that have not completed will be rolled back at startup.  This crash recovery process could take longer than normal if there was a long-running transaction running when the service was stopped.  Until the crash recovery process is completed on the database, it is unavailable to your applications. If restarting IIS fixes the problem, then the problem might not have been inside SQL Server.  Prior to taking this step, you should do analysis of the above mentioned things. If you can think of other reasons why the blog reader is facing this issue a few times a week, I'd love to hear your thoughts via a blog comment.

  • C#: Is this the correct way to use the SqlDataReader for DAAB

    - by Luke101
    Hello, I have just started using the Data Access Application Block from microsoft. There are very few instructions on the correct way to use the library. Just wanted to know if this is the correct way to use the data reader. SqlDataReader reader = SqlHelper.ExecuteReader(config.ConnectionString, CommandType.Text, "select * from category"); List<string> a = new List<string>(); using (reader) { while (reader.Read()) { string t = reader.GetString(1); a.Add(t); } return a; } will everything get closed doing it this way? Is there any chance of memory leaks?

  • How I start a process to run logcat on Android?

    - by tangjie
    I want to read Android system level log file.So I use the following code: Process mLogcatProc = null; BufferedReader reader = null; try { mLogcatProc = Runtime.getRuntime().exec( new String[] { "logcat", "-d", "AndroidRuntime:E [Your Log Tag Here]:V *:S" }); reader = new BufferedReader(new InputStreamReader(mLogcatProc .getInputStream())); String line; final StringBuilder log = new StringBuilder(); String separator = System.getProperty("line.separator"); while ((line = reader.readLine()) != null) { log.append(line); log.append(separator); } } catch (IOException e) {} finally { if (reader != null) try { reader.close(); } catch (IOException e) {} } I also used in AndroidManifest.xml. But I can't read any line. The StringBuilder log is empty. And the method mLogcatProc.waitFor return 0. So how can I read the log ?

  • How to move the mouse

    - by GroundZero
    I'm making a little bot in C#. At the moment it works pretty well, it can load text from a file and type it for you. But for now, I need to manualy click the textfield to put the focus on it, remaximize my form and then click the Type-button. After the typing, I need to manualy slide the scorebar and press submit. I'd like to know how I can move my mouse with C# and if possible, if possible I'd like to load the mouse positions from a xml-file. I need to move to the textfield, click in it to focus on it, start the type script, move to the slider, hold the mouse down on it while dragging, releasing it on the correct position & clicking on the submitbutton This is what I have for now: To load in the variables, I'm using this script: private void Initialize() { XmlTextReader reader = new XmlTextReader(Application.StartupPath + @"..\..\..\CursorPositions.xml"); while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: // The node is an element. element = reader.Value; break; case XmlNodeType.Text: //Display the text in each element. switch (element) { case "Textbox-X": textX = int.Parse(reader.Value); break; case "Textbox-Y": textY = int.Parse(reader.Value); break; case "SliderBegin-X": sliderX = int.Parse(reader.Value); break; case "SliderBegin-Y": sliderY = int.Parse(reader.Value); break; case "SubmitButton-X": submitX = int.Parse(reader.Value); break; case "SubmitButton-Y": submitY = int.Parse(reader.Value); break; } break; } } This is the xml-file: <?xml version="1.0" encoding="utf-8" ?> <CursorPositions> <Textbox-X>430</Textbox-X> <Textbox-Y>270</Textbox-Y> <SliderBegin-X>430</SliderBegin-X> <SliderBegin-Y>470</SliderBegin-Y> <SubmitButton-X>860</SubmitButton-X> <SubmitButton-Y>365</SubmitButton-Y> </CursorPositions> To move the mouse I'm using this piece of code: public partial class FrmMain : Form { [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo); public const int MOUSEEVENTF_LEFTDOWN = 0x0002; public const int MOUSEEVENTF_LEFTUP = 0x0004; public const int MOUSEEVENTF_RIGHTDOWN = 0x0008; public const int MOUSEEVENTF_RIGHTUP = 0x0010; ... private void btnStart_Click(object sender, EventArgs e) { // start button (de)activates loop if (!running) { btnStart.Text = "Stop"; btnStart.Cursor = Cursors.No; running = true; } else { btnStart.Text = "Start"; btnStart.Cursor = Cursors.AppStarting; running = false; } while (running) { // move to textbox & type Cursor.Position = new Point(textX, textY); mouse_event(MOUSEEVENTF_LEFTDOWN, textX, textY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, textX, textY, 0, 0); Type(); // wait 90 seconds till slider available Thread.Sleep(90 * 1000); // move to slider & slide according to score Cursor.Position = new Point(sliderX, sliderY); mouse_event(MOUSEEVENTF_LEFTDOWN, sliderX, sliderY, 0, 0); Cursor.Position = new Point(sliderX + 345 / 10 * score, sliderY); mouse_event(MOUSEEVENTF_LEFTUP, sliderX + 345 / 10 * score, sliderY, 0, 0); // submit Cursor.Position = new Point(submitX, submitY); mouse_event(MOUSEEVENTF_LEFTDOWN, submitX, submitY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, submitX, submitY, 0, 0); // wait 10 sec to be sure it's submitted Thread.Sleep(10 * 1000); // refresh page SendKeys.SendWait("{F5}"); // get new text NewText(); // wait 10 sec to refresh and load song Thread.Sleep(10 * 1000); } } } PS: I get the coordinates via my form. I've got 2 labels that show my X & Y coordinates. To capture them outside the form, I press and hold my Left Mouse Button and 'drag' it outside the form to the correct place. This way I get the coordinates of my mouse outside the form

  • Force IOException during file reading

    - by DixonD
    I have the piece of code that reads data from file. I want to force IOException in this code for testing purpose (I want to check if code throws correct custom exception in this case). Is there a some way to create a file which is protected from being read, for example? Maybe dealing with some security checks can help? Please, note that passing name to not-existent file cannot help, because FileNotFoundException has separate catch clause. Here peace of code for better undestanding of question: BufferedReader reader = null; try { reader = new BufferedReader(new FileReader(csvFile)); String rawLine; while ((rawLine = reader.readLine()) != null) { // some work is done here } } catch (FileNotFoundException e) { throw new SomeCustomException(); } catch (IOException e) { throw new SomeCustomException(); } finally { // close the input stream if (reader != null) { try { reader.close(); } catch (IOException e) { // ignore } } }

  • SQL use comma-separated values with IN clause

    - by user342944
    I am developing an ASP.NET application and passing a string value like "1,2,3,4" into a procedure to select those values which are IN (1,2,3,4) but its saying "Conversion failed when converting the varchar value '1,2,3,4' to data type int." Here is the aspx code: private void fillRoles() { /*Read in User Profile Data from database */ Database db = DatabaseFactory.CreateDatabase(); DbCommand cmd = db.GetStoredProcCommand("sp_getUserRoles"); db.AddInParameter(cmd, "@pGroupIDs", System.Data.DbType.String); db.SetParameterValue(cmd, "@pGroupIDs", "1,2,3,4"); IDataReader reader = db.ExecuteReader(cmd); DropDownListRole.DataTextField = "Group"; DropDownListRole.DataValueField = "ID"; while (reader.Read()) { DropDownListRole.Items.Add((new ListItem(reader[1].ToString(), reader[0].ToString()))); } reader.Close(); } Here is my procedure: CREATE Procedure [dbo].[sp_getUserRoles](@pGroupIDs varchar(50)) AS BEGIN SELECT * FROM CheckList_Groups Where id in (@pGroupIDs) END

  • Inferring type from method generics

    - by ng
    I am from a Java background and I am looking from the equivalent in c# for the following. public interface Reader { <T> T read(Class<? extends T> type); } Such that I can do the following, constraining the parameter and inferring the return type. Cat cat = reader.read(Cat.class); Dog dog = reader.read(Dog.class); I was hoping something like this would work in c# but I am not sure it will. public interface Reader { T Read<T>(); } And and do this. public class TypeReader : Reader { public T Read<T>() { Type type = T.GetType(); ... } } Is something like this even possible in c#?

  • what does this string.format piece of code do?

    - by jbkkd
    I have this piece of code in c#: private static void _constructRow(SqlDataReader reader, system.IO.StreamWriter stwr, bool getColumnName) { for (int i = 0; i < reader.FieldCount; i++) stwr.Writeline(String.Format("<td>{0}</td"), getColumnName ? reader.GetName(i) : reader.GetValue(i).ToString())); } I'm trying to understand what the part that start with "getColumnName ?" and ends with ".ToString()" does. I understood that it is a system.object type, but I have no idea what it specifically does or how it works. I want that because of this: "reader" had multiple rows in it, and I want to writeline only specific rows. If anyone can help me on either of those, I'd be grateful.
