  • FastMM and Dynamically loaded DLLs

    - by Vegar
    I have a host application, that loads a dozen of libraries at start up. I want to switch from Delphi 7s default memory manager to the full version of FastMM4 for better mem leak reporting. Should I include FastMM4 in the uses section of both the host application and the libraries? What about shared runtime packages? -Vegar

  • Get_user running at kernel mode returns error

    - by Fangkai Yang
    Hi, all, I have a problem with get_user() macro. What I did is as follows: I run the following program int main() { int a = 20; printf("address of a: %p", &a); sleep(200); return 0; } When the program runs, it outputs the address of a, say, 0xbff91914. Then I pass this address to a module running in Kernel Mode that retrieves the contents at this address (at the time when I did this, I also made sure the process didn't terminate, because I put it to sleep for 200 seconds... ): The address is firstly sent as a string, and I cast them into pointer type. int * ptr = (int*)simple_strtol(buffer, NULL,16); printk("address: %p",ptr); // I use this line to make sure the cast is correct. When running, it outputs bff91914, as expected. int val = 0; int res; res= get_user(val, (int*) ptr); However, res is always not 0, meaning that get_user returns error. I am wondering what is the problem.... Thank you!! -- Fangkai

  • Netlogo: error when putting variable in table, only constants allowe??

    - by Chantal
    Hello, Currently I am working on a Netlogo program where I need to use nodes and links for vehicle routing problem. (links are called streets in the program) Here I have some practical problems of how to input variable linkspeed in a table with another node. Constants like 200 etc are fine. Online I found some examples where variables are used, but I do not know why I keep getting the following error: Expected a constant. (or why netlogo expects a constant) Here is the relevant piece of code: extensions [table] streets-own [linkspeed linktoll] nodes-own [netw] ;; In another piece of code linkspeed is assigned successfully to the links to cheapcalc ;; start conditions set costs very high 300000 ;; state 3 unsearched state 2 searching state 1 searched (for later purposes) ask nodes [ set i 0 set j count nodes set netw table:make while [i < j][ table:put netw (i) [3000000 3] set i (i + 1)]] set i 0 let k 0 ask node 35 ;; here i use node 35 as an example. ;; node 35 is connected to node 34, 36, 20 and 50 [table:put netw (35) [0 1] ;; node need to search costs to travel to itself ;; putting constants is ok. while [i < j] [ask my-links [ask both-ends [if (who != 35) [set color blue ;; set temp ([linkspeed] of street 35 who) ;; here my real goal is to put this in stat of i. but i is easier than linkspeed. table:put netw (who) [ i 2 ] ] ] ] set i (i + 1)] ] ;; next node for later, no it is just repetition of the same. end I hope somebody knows what is going on... Kind regards, Chantal

  • Ldap_add() : Invalid Syntax

    - by Suezy
    I have a program here that uses the ldap_add, when i try to run the program, it displays an error: Warning: ldap_add() [function.ldap-add]: Add: Invalid syntax in /var/www/suey/costcenter.20090617.php on line 780 My lil' code here is: $ldapservers='ourServer'; $ds = ldap_connect($ldapservers); if ($ds){ $r = ldap_bind($ds, $ldaprootun, $ldaprootpw); $add = ldap_add($ds, "uid=$fuid, $ldapbasedn", $infonew); } ldapbasedn is set to o=ourGroup; infonew is an array of entries (person information) and am so sure that the array is not empty because i already tested it. the uid is not empty too. What could be wrong? Is it the entries(array)? or the server am trying to connect to? I tried testing the ldap_bind, and it also works well too..hmmm.. Pls help.. thanks! I found the problem.. it's in the index infonew["createdBy"] = getenv("REMOTE_USER"); it returns NULL! now, is that right?

  • Exception on inserting into Access 2010 in C Sharp

  • Error loading shared libraries

    - by user459811
    Hi, I'm running eclipse on Ubuntu using a g++ compiler and I'm trying to run a sample program that utilizes xerces. The build produced no errors however, when i attempted to run the program, I would receive this error: "error while loading shared libraries: libxerces-c-3.1.so: cannot open shared object file: No such file or directory" libxerces-c-3.1.so is in the directory /opt/lib which I have included as a library in eclipse. The file is there when I checked the folder. When I perform an 'echo $LD_LIBRARY_PATH', /opt/lib is also listed. Any ideas into where the problem lies? Thanks. An 'ldd libxerces-c-3.1.so' command yields the following output: linux-vdso.so.1 => (0x00007fffeafff000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007fa3d2b83000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007fa3d2966000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007fa3d265f000) libm.so.6 => /lib/libm.so.6 (0x00007fa3d23dc000) libc.so.6 => /lib/libc.so.6 (0x00007fa3d2059000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007fa3d1e42000) /lib64/ld-linux-x86-64.so.2 (0x00007fa3d337d000)

  • How do I [legally] get the current first responder on the screen on an iPhone?

    - by Anthony D
    I submitted my app a little over a week ago and got the dreaded rejection email today. It reads as follows: Dear -----------, Thank you for submitting --------- to the App Store. Unfortunately it cannot be added to the App Store because it is using a private API. Use of non-public APIs, which as outlined in the iPhone Developer Program License Agreement section 3.3.1 is prohibited: "3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs." The non-public API that is included in your application is firstResponder. Regards, iPhone Developer Program Now, the offending API call is actually a solution I found here on SO: UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow]; UIView *firstResponder = [keyWindow performSelector:@selector(firstResponder)]; So this is my question; How do I get the current first responder on the screen? I'm looking for a legal way that won't get my app rejected. Thanks. I figured this out based on the solution provided by Thomas below. Here is what the final code looks like: @implementation UIView (FindFirstResponder) - (UIView *)findFirstResonder { if (self.isFirstResponder) { return self; } for (UIView *subView in self.subviews) { UIView *firstResponder = [subView findFirstResonder]; if (firstResponder != nil) { return firstResponder; } } return nil; } @end

  • Lazarus Pascal - DB Connection - clarification

    - by itsols
    The following code is from the docs here: Program ConnectDB var AConnection : TSQLConnection; Procedure CreateConnection; begin AConnection := TIBConnection.Create(nil); AConnection.Hostname := 'localhost'; AConnection.DatabaseName := '/opt/firebird/examples/employee.fdb'; AConnection.UserName := 'sysdba'; AConnection.Password := 'masterkey'; end; begin CreateConnection; AConnection.Open; if Aconnection.Connected then writeln('Succesful connect!') else writeln('This is not possible, because if the connection failed, ' + 'an exception should be raised, so this code would not ' + 'be executed'); AConnection.Close; AConnection.Free; end. The main body of the code makes sense to me BUT I don't get where TSQLConnection came from. I cannot use CTRL + Space to autocomplete it either, which means my program has no reference to it. I'm trying to connect to Postgres by the way. Can someone please state what TSQLConnection is? Thanks!

  • Database design MySQL using foreign keys

    - by dscher
    I'm having some a little trouble understanding how to handle the database end of a program I'm making. I'm using an ORM in Kohana, but am hoping that a generalized understanding of how to solve this issue will lead me to an answer with the ORM. I'm writing a program for users to manage their stock research information. My tables are basically like so: CREATE TABLE tags( id INT AUTO_INCREMENT NOT NULL PRIMARY KEY, tags VARCHAR(30), UNIQUE(tags) ) ENGINE=INNODB DEFAULT CHARSET=utf8; CREATE TABLE stock_tags( id INT AUTO_INCREMENT NOT NULL PRIMARY KEY, tag_id INT NOT NULL, stock_id INT NOT NULL, FOREIGN KEY (tag_id) REFERENCES tags(id), FOREIGN KEY(stock_id) REFERENCES stocks(id) ON DELETE CASCADE ) ENGINE=INNODB DEFAULT CHARSET=utf8; CREATE TABLE notes( id INT AUTO_INCREMENT NOT NULL, stock_id INT NOT NULL, notes TEXT NOT NULL, FOREIGN KEY (stock_id) REFERENCES stocks(id) ON DELETE CASCADE, PRIMARY KEY(id) ) ENGINE=INNODB DEFAULT CHARSET=utf8; CREATE TABLE links( id INT AUTO_INCREMENT NOT NULL, stock_id INT NOT NULL, links VARCHAR(2083) NOT NULL, FOREIGN KEY (stock_id) REFERENCES stocks(id) ON DELETE CASCADE, PRIMARY KEY(id) ) ENGINE=INNODB DEFAULT CHARSET=utf8; How would I get all the attributes of a single stock, including its links, notes, and tags? Do I have to add links, notes, and tags columns to the stocks table and then how do you call it? I know this differs using an ORM and I'd assume that I can use join tables in SQL. Thanks for any help, this will really help me understand the issue a lot better.

  • How to link pnglite library in c?

    - by zaplec
    Hi, I installed from kubuntu's package management this handy pnglite library. It contains just one header file "pnglite.h" and one object file "pnglite.o". I have found out where those files are, but I don't know how to link them. I'm using netbeans, but don't know how to link them in there. Also I don't understand how to link them at console. I have a little test program that I would like to test, but I get the error message "undefined reference to function: XXXXXXX". Both netbeans and at console I'm using gcc. That header file is in /usr/include directory, object file is in /usr/lib directory and my test program is under my programming directory at my home directory. Should I put that header and object into the same directory as where my source is? Or is there a way to link them from their current locations? I know that it should be possible to link them from where they are at the moment and I would like to know and understand how to do that. Any help will be appreciated :)

  • How can I stop and start individual websites in IIS using PowerShell?

    - by Joey Green
    I have multiple sites configured in IIS7 on my Windows7 development machine to run on the same port and usually only run one at a time depending on what I'm working on. I would like to be able to start and stop my development sites from PowerShell instead of having the IIS manager opened. Does anyone have a good resource to point me in the right direction or a script that already accomplishes this? Thanks

  • I seek a PDF paginator

    - by Cameron Laird
    More precisely, I need software that will allow me to consume existing PDF instances, decorate them with page numbers, or page-number-like writing, then write them back to the filesystem. I'll happily pay for an application, or program it myself. I almost certainly require the software run under Linux (Ubuntu, more specifically). iText comes close. iText certainly can read existing PDF instances. While iText is, for this purpose, only a library, and requires me to program a tiny amount to specify where on the page the numbers should appear, I'm happy to do that. I hesitate with iText only because the latest iText license is a headache at certain government agencies (in practice, I'd probably request and pay for a special license), and because, over the last few years, I've observed cases where iText doesn't appear to keep up with the standard, that is, it has more troubles than I expect reading PDFs observed "in the wild". Similarly, every other possibility I know has at least one difficulty: ReportLab would likely require a disproportionate licensing fee for the small value it provides in this situation, and so on. This application requires no particular sophistication with Unicode, fonts, ... I recognize there are plenty of executables and libraries that do some or all of what I require. I welcome any tips on software that is reliable, generally current with PDF practice, flexible/programmable/configurable/..., and "automatable". In the absence of any new insight, I'll likely go with a specific open-source library I don't want to mention now for which I've already contracted enhancements, or perhaps revisit iText.

  • C# - How to change window state of Form, on a different thread?

    - by Dodi300
    Hello. Does anyone know how I can chage the window state of a form, from another thread? This is the code I'm using: private void button4_Click(object sender, EventArgs e) { string pathe = label1.Text; string name = Path.GetFileName(pathe); pathe = pathe.Replace(name, ""); string runpath = label2.Text; Process process; process = new Process(); process.EnableRaisingEvents = true; process.Exited += new System.EventHandler(process_Exited); process.StartInfo.FileName = @runpath; process.StartInfo.WorkingDirectory = @pathe; process.Start(); WindowState = FormWindowState.Minimized; } private void process_Exited(object sender, EventArgs e) { this.WindowState = FormWindowState.Normal; } It's meant to run a program and minimize, then return to the normal state once the program has closed. Although I get this error "Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on." Any idea how to get this to work? Thanks.

  • How to use VBA to colour pie chart

    - by Timon Heinomann
    I have the following code in which the code tries to create a bubble chart with pie charts as the bubbles. As in this version colour themes are used to create a different colour in each pie chart (bulbble) in the function part I have the problem that it works depending on the paths to the colour paletts. Is there an easy way to make the function in a way that it works independently of those paths either by coding a colour for each pie chart segment or by using standardize paths (probably not possible, not preferable). Sub PieMarkers() Dim chtMarker As Chart Dim chtMain As Chart Dim intPoint As Integer Dim rngRow As Range Dim lngPointIndex As Long Dim thmColor As Long Dim myTheme As String Application.ScreenUpdating = False Set chtMarker = ActiveSheet.ChartObjects("chtMarker").Chart Set chtMain = ActiveSheet.ChartObjects("chtMain").Chart Set chtMain = ActiveSheet.ChartObjects("chtMain").Chart Set rngRow = Range(ThisWorkbook.Names("PieChartValues").RefersTo) For Each rngRow In Range("PieChartValues").Rows chtMarker.SeriesCollection(1).Values = rngRow ThisWorkbook.Theme.ThemeColorScheme.Load GetColorScheme(thmColor) chtMarker.Parent.CopyPicture xlScreen, xlPicture lngPointIndex = lngPointIndex + 1 chtMain.SeriesCollection(1).Points(lngPointIndex).Paste thmColor = thmColor + 1 Next lngPointIndex = 0 Application.ScreenUpdating = True End Sub Function GetColorScheme(i As Long) As String Const thmColor1 As String = "C:\Program Files\Microsoft Office\Document Themes 15\Theme Colors\Blue Green.xml" Const thmColor2 As String = "C:\Program Files\Microsoft Office\Document Themes 15\Theme Colors\Orange Red.xml" Select Case i Mod 2 Case 0 GetColorScheme = thmColor1 Case 1 GetColorScheme = thmColor2 End Select End Function The code copies a single chart again and again on the bubbles. So I woudl like to alter the Function (now called Get colourscheme) into a fucntion that assigns a a unqiue rgb colour to each segment of each pie chart

  • Compose path (with boost::filesystem)

    - by ypnos
    I have a file that describes input data, which is split into several other files. In my descriptor file, I first give the path A that tells where all the other files are found. The originator may set either a relative (to location of the descriptor file) or absolute path. When my program is called, the user gives the name of the descriptor file. It may not be in the current working directory, so the filename B given may also contain directories. For my program to always find the input files at the right places, I need to combine this information. If the path A given is absolute, I need to just that one. If it is relative, I need to concatenate it to the path B (i.e. directory portion of the filename). I thought boost::filesystem::complete may do the job for me. Unfortunately, it seems it is not. I also did not understand how to test wether a path given is absolute or not. Any ideas?

  • Show a DB as a directory (Like Sharepoint Does)

    - by Zyd
    Hi, My team and I are programming a sort of Document Manager and the idea is to store them completely on DB. Is there a protocol or Extensions that allows us to show a "Virtual Directory" or files that are really non existent (only in DB). How does Sharepoint do this? I understand that Sharepoint uses WebDav but it implies that the files do exist physically somewhere. We intend to develop this application on .NET 4.0 and deploy it on IIS. Any suggestions? Thanks in advance

  • .NET Splash screen issues

    - by CODe
    I have a splash screen for my C# database application that is called via the Shown event. The splash screen contains some information that is preprocessed when the main form's constructor is called, hence why I'm using the Shown event, because that information should be available. However, when the splash screen is shown, the main form is whited out, and the menu bar, bottom menu bar, and even the gray background are all white and invisible. It looks like the program is hanging, but after the 5 second delay I have built in, the banner goes away and the program is shown normally. Also, on the banner, I have labels that are not shown when the splash screen displays... Here is my code, some reasoning behind why it isn't working would help greatly. SPLASH SCREEN CODE : public partial class StartupBanner : Form { public StartupBanner(int missingNum, int expiredNum) { InitializeComponent(); missingLabel.Text = missingNum.ToString() + " MISSING POLICIES"; expiredLabel.Text = expiredNum.ToString() + " EXPIRED POLICIES"; } } CALLING CODE : private void MainForm_Shown(object sender, EventArgs e) { StartupBanner startup = new StartupBanner(missingPoliciesNum, expiredPoliciesNum); startup.MdiParent = this; startup.Show(); Thread.Sleep(5000); startup.Close(); } Using startup.ShowDialog() shows the correct label information on the splash screen, but that locks up the application, and I need the splash to go away after about 5 seconds, which is why it's a splash. ;)

  • Atomic swap in GNU C++

    - by Steve
    I want to verify that my understanding is correct. This kind of thing is tricky so I'm almost sure I am missing something. I have a program consisting of a real-time thread and a non-real-time thread. I want the non-RT thread to be able to swap a pointer to memory that is used by the RT thread. From the docs, my understanding is that this can be accomplished in g++ with: // global Data *rt_data; Data *swap_data(Data *new_data) { #ifdef __GNUC__ // Atomic pointer swap. Data *old_d = __sync_lock_test_and_set(&rt_data, new_data); #else // Non-atomic, cross your fingers. Data *old_d = rt_data; rt_data = new_data; #endif return old_d; } This is the only place in the program (other than initial setup) where rt_data is modified. When rt_data is used in the real-time context, it is copied to a local pointer. For old_d, later on when it is sure that the old memory is not used, it will be freed in the non-RT thread. Is this correct? Do I need volatile anywhere? Are there other synchronization primitives I should be calling? By the way I am doing this in C++, although I'm interested in whether the answer differs for C. Thanks ahead of time.

  • How to get application context path in spring-ws?

    - by Dhaliwal
    I am using Spring-WS to create a webservice. In my project, I have created a Helper class to reads sample response and request xml file which are located in my /src/main/resource folder. When I am unit-testing my webservice application 'locally', I use the System.getProperty("user.dir") to get the application context folder. The following is a method that I created in the Helper class to help me retrieve the file that I am interested in my resource folder. public static File getFileFromResources(String filename) { System.out.println("Getting file from resource folder"); File request = null; String curDir = System.getProperty("user.dir"); String contextpath = "C:\\src\\main\\resources\\"; request = new File(curDir + contextpath + filename); return request; } However, after 'publishing' the compiled WAR file to the ../webapps folder to the Apache Tomcat directory, I realise that System.getProperty("user.dir") no longer returns my application context path. Instead, it is returning the Apache Tomcat root directory as shown C:\Program Files\Apache Software Foundation\Tomcat 6.0\src\main\resources\SampleClientFile I cant seem to find any information about getting the root folder of my webservice. I have seen examples on Spring web application where I can retrieve the context path by using the following : request.getSession().getServletContext().getContextPath() But in this case, I am using a Spring web application where there is a servlet context in the request. But the Spring-WS, my entry point is an endpoint. How can I get the context path of my webservice application. I am expecting a context path of something like C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\clientWebService\WEB-INF\classes Could someone suggest a way to achieve this?

  • SQLce DAL Linq to Sql or EntityFramework

    - by bretddog
    Hi, I'm learning databases, using SqlCe, and need business object to database mapping. Currently I try to decide if to use Linq to Sql, or EntityFramework. (I understand a bit L2S, but haven't familiarized with EF yet) The program will only be debeloped and used by myself, so I have good control of the priorities: I don't need to consider potential change of database type or data storage type, as I'm quite certain SQLce will stay sufficient. I DO expect continued development and changes to the data scheme while the program is in active use; change business object properties (Hence database columns), and possibly overall table scheme. So old data must be transported to new scheme. I also want to keep a decent degree of layer separation DAL/BLL, although this may not be necessary, it is good for me to learn these principles. My question is: With these priorities, would I have any benefit by choosing either Linq2Sql vs. EntityFramwork? (and please explain why) Btw, the project involves very simple table scheme with only 4-5 tables and very simple relations. Thanks!
