• Changing size of a dynamically allocated matrix

  - by user1309174

  Trying to re-size the shape matrix dynamically. This is part of a drawing program where _capacity is the number of shapes drawn on a frame. Get the error in new Shape about _capacity saying expression needs to have a constant value. void ShapeStore::Grow(int minimumCapacity) { _capacity = max (minimumCapacity, 2 * _capacity); if (_capacity) { Shape ***newData = new Shape[_frames][_capacity]; //figure out this int i; for (int k = 0; k < _frames; k++) for (i=0;i<_count;i++) newData[k][i] = _data[k][i]; delete [] _data; _data = newData; } //*/ }

• Windows/C++: detect when focus has changed between windows (globally)

  - by twig

  I'm trying to find a way to detect when focus is changed to another window (without having to poll every X ms). I've already figured out a way to detect when focus is switched between applications using WH_SHELL and HSHELL_ACTIVATESHELLWINDOW. The problem is I want to detect when focus is switched between dialog/windows within the same app. ie. In Notepad, I can determine when the app switches to Notepad, but I cannot detect when the "Open" or "Save" dialogs appear because the focus is still within the same application.

  - by NLV

  Hello I've the following expression in my report. =FormatNumber(MAX(Fields!Reading.Value, "CellReading_Reading"),3) Now when the dataset is empty 'Fields!Reading.Value' becomes empty and finding their maximum is invalid. How can i check if the entire column is empty? I tried the following with no luck. =iif(IsNothing(Fields!.Reading.Value),"",FormatNumber(MAX(Fields!Reading.Value, "CellReading_Reading"),3)) But still i'm getting #Error in the report. I also checked out link and was not able to get a clue from it. I want to handle it in the report level. Thank you. NLV

• Convert Json date string to JavaScript date object

  - by dagda1

  Hi, I have the following JSON object which has a date field in the following format: { "AlertDate": "\/Date(1277334000000+0100)\/", "Progress": 1, "ReviewPeriod": 12 } I want to write a regular expression or a function to convert it to a javascript object so that it is in the form: { "AlertDate": "AlertDate":new Date(1277334000000), "Progress": 1, "ReviewPeriod": 12 } The above date format fails validation in the JQuery parseJSON method. I would like to convert the 1277334000000+0100 into the correct number of milliseconds to create the correct date when eval is called after validation. Can anyone help me out with a good approach to solving this? Cheers Paul

• How do I include a newline in a text message sent as email from an ASP.Net application?

  - by Tim Goodman

  I have an ASP.Net Application that sends text messages to mobile phones. It does this by sending an email. For instance, if your phone number is 555-555-5555 and your wireless carrier is Verizon, you can send an email to [email protected] and it will show up as a text message. I want to be able to include a newline in the body of the message. How do I do this? Also please note that my ASP.Net program gets the message from a database (MS SQL Server) so what I really need to know is what characters to include in the message body when I store it in my database. I already tried \n but it just showed up in the text message as \n

• How can i test my DB speed? (Learning)

  - by acidzombie24

  I have design a database. Theres no columns with indexing, nor any code for optimizing. I am positive i should index certain columns since i search them a lot. My question is HOW do i test if any part of my database will be slow? ATM I am using sqlite and i will be switching to either MS Sql or MySql based on my host provider. Will creating 100,000 records in each table be enough? Or will that always be fast in sqlite and i need to do 1mil? Do i need 10mil before a database will become slow? Also how do i time it? I am using C# so should i use StopWatch or is there a ADO.NET/Sqlite function i should use?

• Exclude subexpression from regexec in c++

  - by wyatt

  Suppose I was trying to match the following expression using regex.h in C++, and trying to obtain the subexpressions contained: /^((1|2)|3) (1|2)$/ Suppose it were matched against the string "3 1", the subexpressions would be: "3 1" "3" "1" If, instead it were matched against the string "2 1", the subexpressions would be: "2 1" "2" "2" "1" Which means that, depending on how the first subexpression evaluates, the final one is in a different element in the pmatch array. I realise this particular example is trivial, as I could remove one of the sets of brackets, or grab the last element of the array, but it becomes problematic in more complicated expressions. Suppose all I want are the top-level subexpressions, the ones which aren't subexpressions of other subexpressions. Is there any way to only get them? Or, alternatively, to know how many subexpressions are matched within a subexpression, so that I can traverse the array irrespective of how it evaluates? Thanks

• Is there a Windows utility that will let me do multiple programmatic find/replaces on text that I cu

  - by billmaya

  I've inherited some C# code that contains about a thousand lines of source that I need to modify, transforming it from this: newDataRow["to_dir"] = comboBox108.Text; To this: assetAttributes.Add("to_dir", comboBox108.Text); The lines occur in various places throughout the application in groups of 40 or 50. Modifying each line by hand in Visual Studio 2008 can be done but it's labor intensive and prone to errors. Is there a Windows utility out there that will let me cut and paste groups of code into it and then run some sort of reg-ex expression to transform the individual lines one-by-one? I'd also be willing to use some sort of VS 2008 add-in that performed the same set of reg-ex operations against a selection of code. Thanks in advance.

• 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.

• boost timer usage question

  - by stefita

  I have a really simple question, yet I can't find an answer for it. I guess I am missing something in the usage of the boost timer.hpp. Here is my code, that unfortunately gives me an error message: include <boost/timer.hpp> int main() { boost::timer t; } And the error messages are as follows: /usr/include/boost/timer.hpp: In member function ‘double boost::timer::elapsed_max() const’: /usr/include/boost/timer.hpp:59: error: ‘numeric_limits’ is not a member of ‘std’ /usr/include/boost/timer.hpp:59: error: ‘::max’ has not been declared /usr/include/boost/timer.hpp:59: error: expected primary-expression before ‘double’ /usr/include/boost/timer.hpp:59: error: expected `)' before ‘double’ The used library is boost 1.36 (SUSE 11.1). Thanks in advance!

• Controling CRT memory initialization

  - by Ofek Shilon

  Occasionally you meet bugs that are reproducible only in release builds and/or only on some machines. A common (but by no means only) reason is uninitialized variables, that are subject to random behaviour. E.g, an uninitialized BOOL can be TRUE most of the time, on most machines, but randomly be initialized as FALSE. What I wish I would have is a systematic way of flushing out such bugs by modifying the behaviour of the CRT memory initialization. I'm well aware of the MS debug CRT magic numbers - at the very least I'd like to have a trigger to turn 0xCDCDCDCD (the pattern that initializes freshly allocated memory) to zeros. I suspect one would be able to easily smoke out nasty initialization pests this way, even in debug builds. Am I missing an available CRT hook (API, registry key, whatever) that enables this? Anyone has other ideas to get there?

• How to extract object reference from property access lamda

  - by Jim C

  Here's a follow-up question to http://stackoverflow.com/questions/2820660/get-name-of-property-as-a-string. Given a method Foo (error checking omitted for brevity): // Example usage: Foo(() => SomeClass.SomeProperty) // Example usage: Foo(() => someObject.SomeProperty) void Foo(Expression<Func<T>> propertyLambda) { var me = propertyLambda.Body as MemberExpression; var pi = me.Member as PropertyInfo; bool propertyIsStatic = pi.GetGetMethod().IsStatic; object owner = propertyIsStatic ? me.Member.DeclaringType : ???; ... // Execute property access object value = pi.GetValue(owner, null); } I've got the static property case working but don't know how to get a reference to someObject in the instance property case. Thanks in advance.

• 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.

• Why does ElapsedTicks X 10 000 not equal ElapsedMilliseconds for .Net's Stopwatch?

  - by uriDium

  I am trying to performance test some code. I am using a stopwatch. When I output the number of milliseconds it always tells me 0 so I thought that I would try the number of ticks. I am seeing that the number of ticks is about 20 000 to 30 000. Looking at the MSDN at TimeSpan.TicksPerMillisecond it says that is 10 000 ticks per millisecond. In that case why are the elapsed milliseconds on my stopwatch not appearing as 2 or 3? What am I missing? I have even outputed the result on the same line. This is what I get. Time taken: 26856 ticks, 0 ms And it is constant.

• [ASP.NET] How can I HTML-encode a string and use human-readable encoded tags (ex: &ecirc; instead of

  - by Beerdude26

  Greetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as &ecirc; (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example: Dim str as string = HttpUtility;HtmlEncode("vente - en-tête") 'Expected: vente - en-t&ecirc;te 'Actually received: vente - en-t&#234;te Is there a setting or function in ASP.Net to encode a string into HTML resembling the first comment? EDIT: I am looking for this kind of functionality because the text is saved HTML-encoded in the database. The text comes from a bunch of MS Word documents that have been converted to HTML.

• 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?)

• How do you escape double quotes inside a SQL fulltext 'contains' function?

  - by Richard Davies

  How do you escape a double quote character inside a MS SQL 'contains' function? SELECT decision FROM table WHERE CONTAINS(decision, '34" AND wide') Normally contains() expects double quotes to surround an exact phrase to match, but I want to search for an actual double quote character. I've tried escaping it with \, `, and even another double quote, but none of that has worked. P.S. I realize a simple example like this could also be done using the LIKE statement, but I need to use the fulltext search function. The query I provided here has been simplified from my actual query for example purposes.

• Regexp in iOS to find comments

  - by SteveDolphin23

  I am trying to find and process 'java-style' comments within a string in objective-C. I have a few regex snippets which almost work but I am stuck on one hurdle: different options seem to make the different styles work. For example, I am using this to match: NSArray* matches = [[NSRegularExpression regularExpressionWithPattern:expression options:NSRegularExpressionAnchorsMatchLines error:nil] matchesInString:string options:0 range:searchRange]; The options here allow me successfully find and process single line comments (//) but not multiline (/* */), if I change the option to NSRegularExpressionDotMatchesLineSeparators then I can make multiline work fine but I can't find the 'end' of a single line comment. I suppose really I need dot-matches-line-separators but I need a better way of finding the end of a single line comment? The regexp I have so far are: @"/\\*.*?\\*/" @"//.*$" it's clear to see if dot matches a line separator then the second one (single line) never 'finishes' but how do I fix this? I found some suggestions for single line that were more like: @"(\/\/[^"\n\r]*(?:"[^"\n\r]*"[^"\n\r]*)*[\r\n])" But that doesn't' seem to work at all! Thanks in advance for any pointers.

• Regex for zeroing in on build output text error

  - by Mike Atlas

  I'd like to quickly hone in on what failed in a build log output that is nearly 5k lines long, using Notepad++ as my editor for the file. Notepad++ has the nice ability to specify regular expressions, so I am wondering if there is a way to not match: Compile complete -- 0 errors, 0 warnings but to match, for example: Compile complete -- 1 errors, 0 warnings Compile complete -- 100 errors, 0 warnings where the match would be (1 or more) errors. If this isn't possible, I will probably just write a quick line-by-line parsing tool instead, but I was hoping someone on StackOverflow could whip out a regular expression in the same amount of time - I'm definitely not proficient enough with regular expressions to be able to write one for my needs in a short amount of time.

• Is Microsoft CCR gaining any traction?

  - by spender

  Microsoft's Concurrency and Coordination Runtime quite literally saved a project that was running into major issues with deadlocking. Since then I find that I use it more and more frequently for almost anything that requires asynchronous coding producing results that run lighter and faster than before. I can honestly state that it has transformed the way I think about multithread/multicore dev. Despite my personal love for CCR, there appears to be very little buzz surrounding it on the web and was wondering if anyone can offer any reason for this. Are there better alternatives, or is it a lack of promotion from MS, or are people simply happy with the existing tools?

• drop-down combo box-like functionality for queries.

  - by Frank Developer

  Is it possible to provide the following type of fuctionality with informix client tools? As the user types the first two characters of a name, the drop-down list is empty. At the third character, the list fills with just the names beginning with those three characters. At the fourth character, MS-Access completes the first matching name (assuming the combo's AutoExpand is on). Once enough characters are typed to identify the customer, the user tabs to the next field. The time taken to load the combo between keystrokes is minimal. This occurs once only for each entry, unless the user backspaces through the first three characters again. If your list still contains too many records, you can reduce them by another order of magnitude by changing the value of constant conSuburbMin from 3 to 4.

• Stored procedure called from C# executes 6 times longer than from SQL Management studio

  I have search stored procedure which is my performance bottleneck. In order to get control about what is happened, I added logging for all parameters and also execution time in SP. I noticed, that when I call SP from MIcrosoft SQL server management Studio execution time is 1.3-1.6 seconds, but when i call it from C#, it takes 6-8 secods (!!!) Parameters | Time (ms) "tb *"TreeType:259Parents:212fL:13;14fV:0;lcid:2057min:0max:10sort:-1 | 6406 "tb *"TreeType:259Parents:212fL:13;14fV:0;lcid:2057min:0max:10sort:-1 | 1346 SP is called with LINQ. Login settings are same. SP uses full text search What could cause this?

• Visual Studio 2008 error while debugging an app with "uiAccess=true" in the manifest

  I have a C# WinForms application that has "uiAccess" set to "True" in it's manifest file. When I try to start/debug it in Visual Studio 2008 SP1 under Windows 7 x64 (RTM) I get this error: Running an Accessibility application requires following the steps described in Help. The help button is a broken link, and clicking ok just closes the application. It is digitally signed, and I can start it just fine in Windows Explorer. Here is the same bug in MS Connect, but unfortunately it's closed: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=384183 Question: Can anyone else using Vista/Win7 x64 (with UAC enabled) confirm that they experience the same problem?
