  • Multipage WIA scan (docfeeder) scans 1 page and blocks scanner

    - by LRF
    Using C# (VS2008) and WIA - scanning to TIFF format; When I use the scanner for 1 page on the flatbed or document feeder the method executes without any problem. When I load multiple forms into the feeder the execution halts after scanning the first page (keeping status: "scanning to pc") but does not scan the next document(s). The method returns the stream of the first page and halts - am able to save the stream and everything; just am lost at what to do next... What statement am I missing? What am I missing here? TIA!

  • sqlite - any improvements for this attach code (running multiple sql commands transactionally in sql

    - by Greg
    Hi, Is this code solid? I've tried to use "using" etc. Basically a method to pass as sequenced list of SQL commands to be run against a Sqlite database. I assume it is true that in sqlite by default all commands run in a single connection are handled transactionally? Is this true? i.e. I should not have to (and haven't got in the code at the moment) a BeginTransaction, or CommitTransaction. It's using http://sqlite.phxsoftware.com/ as the sqlite ADO.net database provider. private int ExecuteNonQueryTransactionally(List<string> sqlList) { int totalRowsUpdated = 0; using (var conn = new SQLiteConnection(_connectionString)) { // Open connection (one connection so should be transactional - confirm) conn.Open(); // Apply each SQL statement passed in to sqlList foreach (string s in sqlList) { using (var cmd = new SQLiteCommand(conn)) { cmd.CommandText = s; totalRowsUpdated = totalRowsUpdated + cmd.ExecuteNonQuery(); } } } return totalRowsUpdated; }

  • Irrelevant legend information in ggplot2

    - by Dan Goldstein
    When running this code (go ahead, try it): library(ggplot2) (myDat <- data.frame(cbind(VarX=10:1, VarY=runif(10)), Descrip=sample(LETTERS[1:3], 10, replace=TRUE))) ggplot(myDat,aes(VarX,VarY,shape=Descrip,size=3)) + geom_point() ... the "size=3" statement does correctly set the point size. However it causes the legend to give birth to a little legend beneath it, entitled "3" and containing nothing but a big dot and the number 3. This does the same ggplot(myDat,aes(VarX,VarY,shape=Descrip)) + geom_point(aes(size=3)) Yes, it is funny. It would have driven me insane a couple hours ago if it weren't so funny. But now let's make it stop.

  • Generated SQL with PredicateBuilder, LINQPad and operator ANY

    - by Sig. Tolleranza
    I previously asked a question about chaining conditions in Linq To Entities. Now I use LinqKit and everything works fine. I want to see the generated SQL and after reading this answer, I use LinqPad. This is my statement: var predProduct = PredicateBuilder.True<Product>(); var predColorLanguage = PredicateBuilder.True<ColorLanguage>(); predProduct = predProduct.And(p => p.IsComplete); predColorLanguage = predColorLanguage.And(c => c.IdColorEntity.Products.AsQueryable().Any(expr)); ColorLanguages.Where(predColorLanguage).Dump(); The code works in VS2008, compile and produce the correct result set, but in LinqPad, I've the following error: NotSupportedException: The overload query operator 'Any' used is not Supported. How can I see the generated SQL if LINQPad fails?

  • Access Control Lists basics

    - by vtortola
    Hi, I'm gonna add authorization, user and groups management to my application, basically... you will can define a set of permissions for a concrete user or group. For example, you could specify whom can use a concrete resource. So I want to ensure that my assumptions about ACLs are right: A basic rule could be "Grant", "Deny", "NoSet". User permissions have priority over group permissions. "Deny" statement has priority over "Grant". For example, user "u1" belongs to group "A", the resource "X" has this ACL "u1:grant,A:deny" user "u1" should be able to access the resource, shouldn't it? If a resource has no ACL set... does it means that anyone can access it? should I provide a default ACL? Any document about ACL in a general way? Cheers.

  • Are the ASP.net __EVENTTARGET and __EVENTARGUMENT susceptible to SQL injection?

    - by Schleichermann
    A security review was done against one of our ASP.net applications and returned in the test results was a SQL Injection Exposures considered to be a high risk item. The test that was performed passed a SQL statement as the value of the __EVENTTARGET and the __EVENTARGUMENT. I am wondering since these 2 values are ASP.net auto-generated hidden fields used for the Auto-Postback feature of the framework and hold information specific to the controls initiating the postback, is there really the potential for SQL injection if you are never manually calling and or pulling values out of these parameters in your code behind?

  • Excel - Looping through data till it finds the right one

    - by DanoK
    I'm pulling data from one Excel table into another using an IF statement. I want it to check two fields and if it is a match I want it to print something and if it doesn't then I want it to continue searching. If there is no absolute match then leave the field blank. I believe I'm running into an syntax issue but after numerous iterations I can't get it to pull everything over. Here is my current syntax. =IF(BM5<>"External","",IF(AND(S5=VLOOKUP(A5,ExternalOnly,5,FALSE),A5=VLOOKUP(A5,ExternalOnly,1,FALSE)),S5,"")

  • Using the Specification Pattern

    - by Kane
    Like any design pattern the Specification Pattern is a great concept but susceptible to overuse by an eager architect/developer. I am about to commence development on a new application (.NET & C#) and really like the concept of the Specification Pattern and am keen to make full use of it. However before I go in all guns blazing I would be really interested in knowing if anyone could share the pain points that experienced when use the Specification Pattern in developing an application. Ideally I'm looking to see if others have had issues in Writing unit tests against the specification pattern Deciding which layer the specifications should live in (Repository, Service, Domain, etc) Using it everywhere when a simple if statement would have done the job etc? Thanks in advance

  • Jython 2.5.1: "ImportError: No Module named os"

    - by Leonidas
    I looked through the other posts and bug reports and couldn't figure out what's causing this. I'm using Jython 2.5.1, in a Java project in Eclipse (Ubuntu 8.10). It has been added to the project as a standalone .jar file (I just replaced the old Jython 2.1 jar with this one). I'm running a script that uses the threading.py class. At some point the statement "import os" is evaluated from linecache.py and I get this error, which I can't seem to figure out how to fix: 'Execution failed. Traceback (most recent call last): File "<string>", line 1, in <module> File "../lib/python/threading.py", line 6, in <module> import traceback File "../lib/python/traceback.py", line 3, in <module> import linecache File "../lib/python/linecache.py", line 9, in <module> import os ImportError: No module named os'

  • SQL Where question

    - by needshelp
    Hi all, I have a question about case statements and nulls in a where clause. I want to do the following: Declare @someVar int = null select column1 from TestTable t where t = case when @someVar is not null then @someVar else t end Here is the problem: Let's say @someVar is null. Let's also say that column1 from TestTable t has NULL column values. Then, my condition t = t in the case statement will always evaluate to false. I basically just want to be able to conditionally filter the column based on the value of @someVar if it's provided. Any help?

  • How to specify dynamic field names in a Linq where clause?

    - by Dr. Zim
    If you create a Filter object that contains criteria for Linq that normally goes in a where clause like this: var myFilterObject = FilterFactory.GetBlank(); myFilterObject.AddCondition("Salary", "lessThan", "40000"); var myResult = myRepository.GetEmployees(myFilterObject); How would you match the Linq field to the Field Name without using a big case statement? return from e in db.Employee where e.Salary < 40000 select new IList<EmployeeViewModel> { Name= e.name, Salary= e.Salary }; I assume you need to send an object to the Repository that specifies filtering so that you only pull what records you need. I assume Linq doesn't pre-compile (unless you create a customized delegate and function), so you should be able to dynamically specify which fields you want to filter. It would be nice if you could do something like e["Salary"] like some type of Expando Object.

  • [GoogleMaps] Get GLatLng from GPoint

    - by Jo Asakura
    Hello everybody, I have a google map with my own map type: var currentProjection = new GMercatorProjection(maxLevels + 1); var mapBounds = new GLatLngBounds(new GLatLng(-9, -15), new GLatLng(9, 15)); var custommap = new GMapType(tilelayers, currentProjection, "Some project"); map.addMapType(custommap); map.setCenter(mapBounds.getCenter(), minLevels, custommap); When user clicks on map then context menu appears (singlerightclick event), from context menu user can add markers and I need a GLatLng value to add marker to the map but singlerightclick event contains only GPoint value. I try to use next statement: map.getCurrentMapType().getProjection().fromPixelToLatLng(pointValueFromEvent, map.getZoom()); but it wasn't helpfull (GLatLng value is outside of my map). I think it's because I use my own map type, how can I get GLatLng value to add the marker? Best regards, Alex.

    While working on iphone security architecture, i came to know that i can run applications from other applications in iphone. referring to the following url http://iphonedevelopertips.com/cocoa/launching-other-apps-within-an-iphone-application.html for example, i can put a link in a website with following hyperlink skype:// will result skype to run and call at particular number. Now i have few concerns here. is there a shell running in background in iphone, so that it allows other application to run basic app commands. if the above statement is true then how can i enable or run commands directly into iphone shell? if above statements are false, then could you please explain how these commands are being executed? is this part of iPhone SDK? or this funcationality is iPhone OS

  • PDO::fetchAll vs. PDO::fetch in a loop

    - by Byron
    Just a quick question. Is there any performance difference between using PDO::fetchAll() and PDO::fetch() in a loop (for large result sets)? I'm fetching into objects of a user-defined class, if that makes any difference. My initial uneducated assumption was that fetchAll might be faster because PDO can perform multiple operations in one statement while mysql_query can only execute one. However I have little knowledge of PDO's inner workings and the documentation doesn't say anything about this, and whether or not fetchAll() is simply a PHP-side loop dumped into an array. Any help?

  • Getting float values out of PostgreSQL

    - by skymander
    I am having trouble retrieving float/real values out of PostgreSQL. For example, I would like to store: 123456789123456, the retrieve that exact same number with a select statement. table tbl (num real) insert into tbl(num) values('123456789123456'); As it is now, if I "select num from tbl" the result is "1.23457e+14" If I run "select CAST(num AS numeric) as num from tbl" the result is 123457000000000 If I run "select CAST(num AS float) as num from tbl" the result is 123456788103168 (where did this number come from) How on earth can I select the value and get "123456789123456" as the result? Thanks so much in advance

  • How do I export a large table into 50 smaller csv files of 100,000 records each

    - by Eddie
    I am trying to export one field from a very large table - containing 5,000,000 records, for example - into a csv list - but not all together, rather, 100,000 records into each .csv file created - without duplication. How can I do this, please? I tried SELECT field_name FROM table_name WHERE certain_conditions_are_met INTO OUTFILE /tmp/name_of_export_file_for_first_100000_records.csv LINES TERMINATED BY '\n' LIMIT 0 , 100000 that gives the first 100000 records, but nothing I do has the other 4,900,000 records exported into 49 other files - and how do I specify the other 49 filenames? for example, I tried the following, but the SQL syntax is wrong: SELECT field_name FROM table_name WHERE certain_conditions_are_met INTO OUTFILE /home/user/Eddie/name_of_export_file_for_first_100000_records.csv LINES TERMINATED BY '\n' LIMIT 0 , 100000 INTO OUTFILE /home/user/Eddie/name_of_export_file_for_second_100000_records.csv LINES TERMINATED BY '\n' LIMIT 100001 , 200000 and that did not create the second file... what am I doing wrong, please, and is there a better way to do this? Should the LIMIT 0 , 100000 be put Before the first INTO OUTFILE statement, and then repeat the entire command from SELECT for the second 100,000 records, etc? Thanks for any help. Eddie

  • Why does GetSqlDecimal throw when GetDecimal doesn't?

    - by I. J. Kennedy
    I have a database table that has a column of type money, allowing nulls. Using a SqlDataReader named reader, I can do decimal d = reader.GetDecimal(1); which works, unless of course we're reading a null. If I try using SqlDecimal instead--and I thought the whole point of the SqlTypes was to deal with nulls--then I get an invalid cast, whether or not the value is null. SqlDecimal s = reader.GetSqlDecimal(1); // throws an invalid cast exception What am I doing wrong? Do I really have to write a conditional statement to shepherd the value from the database to a SqlDecimal variable?

  • About "If.." in Scheme (plt-scheme)

    - by Amit
    I had a pretty simple requirement in my Scheme program to execute more than one statement, in the true condition of a 'if'. . So I write my code, something like this: (if (= 1 1) ((expression1) (expression2)) ; these 2 expressions are to be executed when the condition is true (expression3) ) Obviously, the above doesn't work, since I have unintentionally created a # procedure with # arguments. So, to get my work done, I simply put the above expressions in a new function and call it from there, in place of the expression1, expression2. It works. So, my point here is: is there any other conditional construct which may support my requirement here?

  • Is there a log file analyzer for log4j files?

    - by Juha Syrjälä
    I am looking for some kind of analyzer tool for log files generated by log4j files. I am looking something more advanced than grep? What are you using for log file analysis? I am looking for following kinds of features: The tool should tell me how many time a given log statement or a stack trace has occurred, preferably with support for some kinds of patterns (eg. number of log statements matching 'User [a-z]* logged in'). Breakdowns by log level (how many INFO, DEBUG lines) and by class that initiated the log message would be nice. Breakdown by date (how many log statements in given time period) What log lines occur commonly together? Support for several files since I am using log rolling Hot spot analysis: find if there is a some time period when there is unusually high number of log statements Either command-line or GUI are fine Open Source is preferred but I am also interested in commercial offerings My log4j configuration uses org.apache.log4j.PatternLayout with pattern %d %p %c - %m%n but that could be adapted for analyzer tool.

  • StreamReader.ReadToEnd() returning an empty string

    - by axk
    I have a method private static String DecompressAndDecode(byte[] data) { GZipStream decompressor = new GZipStream(new MemoryStream(data), CompressionMode.Decompress); StreamReader decompressed = new StreamReader(decompressor, Encoding.UTF8); String result = decompressed.ReadToEnd(); return result; } I have some GZipped text as input and the result is supposed to be a String representation of this text. The problem is that the method returns an empty string. What is puzzling me is that when I step trough the method in debug mode and reach the return statement the result variable is an empty string but if I create a watch for the decompressed.ReadToEnd() expression it returns me the text. What I would expect at this point is the result variable to contain the text and the decompressed.ReadToEnd() expression evaluating to an empty string. (Reevaluating the decompressed.ReadToEnd() expression returns an empty string as expected). There must be something obvious I'm missing here.
