• PrintingPermissionLevel, SafePrinting, and restrictions

  - by Steve Cooper

  There is a PrintingPermission attribute in the framework which takes a PrintingPermissionLevel enumeration with one of these values; NoPrinting: Prevents access to printers. NoPrinting is a subset of SafePrinting. SafePrinting: Provides printing only from a restricted dialog box. SafePrinting is a subset of DefaultPrinting. DefaultPrinting: Provides printing programmatically to the default printer, along with safe printing through semirestricted dialog box. DefaultPrinting is a subset of AllPrinting. AllPrinting: Provides full access to all printers. The documentation is really sparse, and I wondered if anyone can tell me more about the SafePrinting option. What does the documentation mean when it says "Provides printing only from a restricted dialog box." I have no idea what this means. Can anyone shed any light? This subject is touched in the MS certification 70-505: TS: Microsoft .NET Framework 3.5, Windows Forms Application Development and so I'm keen to find out more.

• sql server bulk copy out/postgres copy from infile

  - by Chris Curvey

  I'm starting a conversion of a system from MS SQL Server to Postgres. I have the table structures converted, and I use "bcp" to get the data out of SQL Server. ERROR: invalid byte sequence for encoding "UTF8": 0x80 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". CONTEXT: COPY cm_outgoing, line 200: "200 c:\temp\200.xml 2009-10-10 01:50:44.000 1900-01-01 00:00:00.000" I've already used "sed" to get rid of the NUL (0x00) entries in the file, and I can't find any instances of 0x80 in the file that I'm trying to import. Any thoughts? Is there an easier way?

• How to do insert one row from one table to another table(what has less columns)?

  - by chobo2

  Hi I am trying to find rows that are not in one table and insert them into another. The table I am trying to insert into has less columns then the other one. These columns are null but it would be cool if I could hardcode a value before I do the insert. But I am having so much trouble with just trying to get it to insert. I have something like this SELECT p.ProductId, p.ProductName INTO SomeTable FROM Product as p WHERE p.ProductName != 'iPad' I will get a error like this though Msg 4104, Level 16, State 1, Line 1 The multi-part identifier "p.ProductId" could not be bound. I am not sure what I am doing wrong. I copied and pasted the names in so I don't think it is a spelling mistake. I am using ms sql 2005 express.

• converting tabular structures in a Word document into an actual table or reading data from the tabul

  - by Chris

  I have a macro which can read the last cell/column of all tables in a Word 2003/2007 document and store the data in an MS-Access table. But, some Word documents have the data in structures like a table format but are not actually tables. The structure looks like a table, but the table borders are actually line connectors. These documents were created by a software(VeryPDF PDF to Word converter) which converted the PDF documents(the original format these documents were) into Word documents. Is there a way I can convert/replace the tabular structures with actual tables in Word so that I can use the macro? Or, is there a way I can read the value of the last column from the tabular structures using some VBA code? Any advice would be appreciated.

• Solr adding document cycle & wait on response issue

  - by user1585896

  I am trying to send http post request to Solr for adding 50000 documents (all individual request one after another in while loop). I am using DefaultHttpClient in java to connect to Solr and when I use execute method on my HttpPost Solr takes 3 to 4 ms to response. I have commit=false, autoCommit=false, autoSoftCommit=false. My question is why it takes that much time to response and why cycle it follows to add new document. Basically I want to send add request but do not want to commit to see how many request can Solr handle without doing any kind of commits(without having to do any disk access). My guess is with above parameter tuned off I should be hitting Solr about 10000 times every second, but my result is 300 times a second. I am generating random data to add in my code.

• MSV1_0 Subauthentication Package Registration

  - by BigShot

  Hi; I'm trying to register a simple MSV1_0 subauthentication package for MS Windows Server 2003. I created a dll which implements required functions described in MSDN. I copied my dll to system32 folder. After that, I created a registry key Auth255 (I also tried Auth128) with a REG_SZ value ,which specifies my dll name, to this location; HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\MSV1_0. I expect that it will create a test.txt file for debugging puposes when the dll is called, but it doesn't create the file. How can I make this work?

• Parent/Child forms communication issue

  - by user361583

  Hi, I am very new to Visual C++ programming, but I have to write simple program which needs to do two things: ( I am using MS Visual C++ ) main ( parent ) form should be displayed when program starts, and after clicking a button on it, second form should be shown. Second form ( child ) also has a button, but this one should ( after clicking, of course ) show current X,Y child form position but on ( important ): parent form. And this is where i got stuck. I can display child form with: a) adding #include "child.h" in parent form.h b) adding child ^child_form; in public: section and afterwards using: child_form = gcnew child(); child_form-Show(); I was googling for two days now and cannot find a way to get it the other way: click on a button on child_form and display it's coordinates on parent form on label-text :/ when i tried to add #include "child.h" in child_form I just got error saying: "there are to many include files..." I really need to get this done and I would really appreciate any suggestions. Thanks in advance :)

• Manipulating both unicode and ASCII character set in C#

  - by Murlex

  I have this mapping in my C# application string [,] unicode2Ascii = { { "&#3001;", "\x86" } }; ஹ - is the unicode value for a tamil literal "ஹ". This is the raw hex literal for the unicode value saved by MS Word as a byte sequence. I am trying to map these unicode value "strings" to a hex value under 255 (so as to accommodate non-unicode supported systems). I trying to use string.replace like this: S = S.replace(unicode2Ascii[0,0], unicode2Ascii[0,1]); However the resultant ouput has a ? instead of the actual hex 0x86 stored. Any pointer on how I could set the encoding for the second element of that array to something like windows-1252? Or is there a better way to do this conversion? thanks in advance

• Fastest way for inserting very large number of records into a Table in SQL

  - by Irchi

  The problem is, we have a huge number of records (more than a million) to be inserted into a single table from a Java application. The records are created by the Java code, it's not a move from another table, so INSERT/SELECT won't help. Currently, my bottleneck is the INSERT statements. I'm using PreparedStatement to speed-up the process, but I can't get more than 50 recods per second on a normal server. The table is not complicated at all, and there are no indexes defined on it. The process takes too long, and the time it takes will make problems. What can I do to get the maximum speed (INSERT per second) possible? Database: MS SQL 2008. Application: Java-based, using Microsoft JDBC driver.

• Marvell C++ compiler (for Windows CE) for building Qt

  - by vnm

  Hello, I was able to build Qt 4.5 for Windows CE (ARM4VI) using MS VisualC++ compiler. Now, I am trying to compile Qt 4.5 for Windows CE 5.0 using Marvel C++ compiler v 2.2 (former Intel C++ compiler for XScale architecture) for achieving some performance benefit. It seems, that this compiler not officially supported for building Qt by trolltech (no appropriate mkspec in mkspec's folder of Qt folder). So, my questions: Is it worth to trying build Qt by this compiler for achieving performance enhancement ? Is there any way for building Qt using Marvell C++ compiler (by creating my own mkspec or something like that)?

• Edit strings vars in compiled exe? C++ win32

  - by extintor

  I want to have a few strings in my c++ app and I want to be able to edit them later in the deployed applications (the compiled exe), Is there a way to make the exe edit itself or it resources so I can update the strings value? The app checks for updates on start, so I'm thinking about using that to algo send the command when I need to edit the strings (for example the string that contains the url used to check for updates). I don't want to use anything external to the exe, I could simply use the registry but I prefer to keep everything inside the exe. I am using visual studio 2010 c++ (or any other version of ms visual c++).

• Leaving SQL Management open on the internet

  - by Tim Fraud

  I am a developer, but every so often need access to our production database -- yeah, poor practice, but anyway... My boss doesn't want me directly on the box using RDP, and so we decided to just permit MS SQL Management Console access so that I can do my tasks. So right now we have the SQL box somewhat accessible on the internet (on port 1433 if I am not mistaken), which opens a security hole. But I am wondering, how much of an uncommon practice is this, and what defaults should I be concerned about? We use MSSQL2008 and I created an account that has Read-Only access, because my production tasks only need that. I didn't see any unusual default accounts with default passwords on the system, so I would be interested to hear your take. (And of-course, is there a better way?)

• Mass data store with SQL SERVER

  - by Leo

  We need management 10,000 GPS devices, each GPS device upload a GPS data every 30 seconds, these data need to store in the database(MS SQL Server 2005). Each GPS device daily data quantity is: 24 * 60 * 2 = 2,880 10 000 10,000 GPS devices daily data quantity is: 10000 * 2880 = 28,800,000 Each GPS data approximately 160Byte, the amount of data per day is: 28,800,000 * 160 = 4.29GB We need hold at least 3 months of GPS data in the database, My question is: 1, whether SQL Server 2005 can support such a large amount of data store? 2, How to plan data table? (all GPS data storage in one table? Daily table? Each GPS device with a GPS data table?) The GPS data: GPSID varchar(21), RecvTime datetime, GPSTime datetime, IsValid bit, IsNavi bit, Lng float, Lat float, Alt float, Spd smallint, Head smallint, PulseValue bigint, Oil float, TSW1 bigint, TSW1Mask bigint, TSW2 bigint, TSW2Mask, BSW bigint, StateText varchar(200), PosText varchar(200), UploadType tinyint

• Grouping date periods (by number of days) but exclude the weekends?

  - by tonyyeb

  I have a table with start and end dates in. My goal is to have a table that has grouped these dates into how many days the period spans. I thought I had the solution with a simple SQL statement (MS SQL Server 2005) but I want to exclude weekends. SELECT DATEDIFF(D, StartDate, EndDate)+1 AS Days, COUNT(ID) as Count FROM myDateTable GROUP BY DATEDIFF(D, StartDate, EndDate) This gives a record set of: Days Count 1 4 2 2 4 1 7 2 Is this possible to exclude the weekends in the SQL statement and if not can it be done using ASP and a array perhaps?

• How to do a batch update?

  - by chobo2

  Hi I am wondering is there a way to do batch updating? I am using ms sql server 2005. I saw away with the sqlDataAdaptor but it seems like you have to first the select statement with it, then fill some dataset and make changes to dataset. Now I am using linq to sql to do the select so I want to try to keep it that way. However it is too slow to do massive updates. So is there away that I can keep my linq to sql(for the select part) but using something different to do the mass update? Thanks

• Microsoft Enterprise Logging Application Block - Reading Log File

  - by Or A

  Hi, I'm using MS log application block for logging my application event into a file called app-trace.log which located on the c:\temp folder. I'm trying to find the best way to read this file at runtime and display it when the user asks for it. now i have 2 issues: it seems that this kind of feature is not supported by the framework, hence i have to write this reader myself. am i missing something here? is there any better way of getting this data (w/o buffering it in the memory or saving it into another file). if i'm taking the only alternative that left for me, and implementing the reader myself, when i'm tring to do: System.IO.FileStream fs = new System.IO.FileStream(@"c:\temp\app-trace.log", FileMode.Open, FileAccess.Read); i'm getting "File being used by another process c#", probably the file is locked by the application block. is there any way to access and read it anyhow? Thank

• Are there any sFTP clients that support a proxy that uses NTLM authentication?

  - by Iraklis

  The title pretty much summarizes the question. We have deployed an sFTP server that needs to be accessed from our client's MS Windows Pc's that reside within a restricted local area network. The only way they can get out for their Intranet is to use an HTTP proxy that requires NTLM authentication. From what I understand all open-source sFTP clients (FilleZilla,WinSCP,etc) do NOT support NTLM authentication (Because of legal issues). I know that there are workarounds to this (installing a local proxy at the machine that understands NTLM) but this would break all sorts of security policies of our client. So my question is : Does anyone know of any sFTP client that supports NTLM ?

• sql: DELETE + INSERT vs UPDATE + INSERT

  - by user93422

  A similar question has been asked, but since it always depends, I'm asking for my specific situation separately. I have a web-site page that shows some data that comes from a database, and to generate the data from that database I have to do some fairly complex multiple joins queries. The data is being updated once a day (nightly). I would like to pre-generate the data for the said view to speed up the page access. For that I am creating a table that contains exact data I need. Question: for my situation, is it reasonable to do complete table wipe followed by insert? or should I do update,insert? SQL wise seems like DELETE + INSERT will be easier (it is single SQL expression). EDIT: RDBMS: MS SQL Server 2008 Ent

• Sql join, 2 tables, same fields

  - by Lobuno

  I have 2 tables. To simplify: Table 1, users: userId int, userName nvarchar(50) Table 2 , messages: msgId int, msgFrom int, msgTo int... msg1 and msg2, both contain userId. Now I want to get all messages, but instead of the msgFrom I want the user name. I know what to do here: select tabMessages.*, tabUsers.userName as Sender from tabMessages inner join tabUsers on msgFrom=userId where msgId = @someParameter; Everything works fine and dandy. The same to get the user name instead of msgTo. Now the problem is, how do I do to get BOTH fields in the same call? I want to get the table as msgId, msgFrom, msgTo, Sender, Recipient. I have tried as: select tabMessages.*, tabUsers.userName as Sender, tabUsers.userName as Recipient from tabMessages inner join tabUsers on msgFrom=userId and msgTo=userId where msgId = @someParameter; but that doesn't work. I'm using Ms sql2000 by the way.

• is there any Simple opensource live audio streaming Server using WCF? (see specification below)

  - by Ole Jak

  is there any Simple opensource live audio streaming Server using WCF? I need it to have simple structure: it should listen to some url format like http://example.com/service/stream?write&id=ANY_STRING and if any data comes to such address format it'll start making it avaliable by something like this http://example.com/service/stream?read&id=ANY_STRING Main thing here to be able to stream live data thru WCF service not buffering it just sharing stream. So can please any one help me with such idea? I think not only I have seen such problem with WCF alot on different sites so answer will help the WCF comunyty alot. I hope. BTW: I know some people say WCF is not prepared for live streaming over bacikHTTPbinding but hey! We all need it to, and we ask MS alot so some day they'll make it beter and we all want to be prepared for it.
