  • Delphi TerminateThread equivalent for Android

    - by Martin
    I have been discussing a problem on the Indy forums related to a thread that is not terminating correctly under Android. They have suggested that there may be an underlying problem with TThread for ARC. Because this problem is holding up the release of a product a work around would be to simply forcibly terminate the thread. I know this is not nice but in this case I cant think of a side effect from doing so. Its wrong but its better than a deadlocked app. Is there a way to forcibly terminate a thread under Android like TerminateThread does under windows? Martin

  • Accessing data stored in another unit Delphi

    - by Hendriksen123
    In Unit2 of my program i have the following code: TValue = Record NewValue, OldValue, SavedValue : Double; end; TData = Class(TObject) Public EconomicGrowth : TValue; Inflation : TValue; Unemployment : TValue; CurrentAccountPosition : TValue; AggregateSupply : TValue; AggregateDemand : TValue; ADGovernmentSpending : TValue; ADConsumption : TValue; ADInvestment : TValue; ADNetExports : TValue; OverallTaxation : TValue; GovernmentSpending : TValue; InterestRates : TValue; IncomeTax : TValue; Benefits : TValue; TrainingEducationSpending : TValue; End; I then declare Data : TData in the Var. when i try to do the following however in Unit1: ShowMessage(FloatToStr(Unit2.Data.Inflation.SavedValue)); I get an EAccessViolation message. Is there any way to access the data stored in 'Data' from Unit1 without getting errors?

  • Delphi - Frac function losing precision.

    - by PeteDaMeat
    I have a TDateTime variable which is assigned a value at runtime of 40510.416667. When I extract the time to a TTime type variable using the Frac function, it sets it to 0.41666666666. Why has it changed the precision of the value and is there a workround to retain the precision from the original value ie. to set it to 0.416667.

  • Delphi debug a wrong unit

    - by Averroes
    This is an odd behaviour by my D2006 as it happens sometimes only. I have a project I want to debug. The file I want to debug is named 'Main.pas'. I have another unrelated project with the same Unit name and sometimes the Debug prompt me the wrong Main file instead of the Main unit from the current project. This have happened to me with other files with the same name. I can't debug then as the debug keys don't work (they just don't do anything). Do you have experienced the same problem? How can I fix it? Thanks.

  • Delphi, VirtualStringTree - classes (objects) instead of records

    - by michal
    I need to use a class instead of record for VirtualStringTree node. Should I declare it standard (but in this case - tricky) way like that: PNode = ^TNode; TNode = record obj: TMyObject; end; //.. var fNd: PNode; begin fNd:= vstTree.getNodeData(vstTree.AddChild(nil)); fNd.obj:= TMyObject.Create; //.. or should I use directly TMyObject? If so - how?! How about assigning (constructing) the object and freeing it? Thanks in advance m.

  • possible UDP attack on BIND?

    - by Waleed Hamra
    hello everyone, i was surprised last month when my EC2 instance (ubuntu precise server), that is supposed to be under the free tier still, accumulated lots of traffic... today, while checking my current billing statement, i noticed i already have tons of traffic, while still in the middle of the month, and i'm fearing what my bill by the end of the month is going to be... i installed bandwidthd, and after few minutes, i noticed lots of UDP traffic to "108.162.233.15". this is apparently a cloudflare IP, and i don't have anything using cloudflare (as far as i know). so i ran "iftop" to see what ports are being used, and i saw the UDP traffic coming from port 80 to my port 53... why would a webserver query dns? so i stopped bind on my server, and ran it in foreground debugging mode, and saw the following query, being repeated continuously: 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: UDP request 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: request is not signed 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: recursion available 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: query 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: query (cache) 'isc.org/ANY/IN' approved 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: send 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: sendto 17-Nov-2012 12:30:58.216 client 108.162.233.15#80: senddone 17-Nov-2012 12:30:58.217 client 108.162.233.15#80: next 17-Nov-2012 12:30:58.217 client 108.162.233.15#80: endrequest 17-Nov-2012 12:30:58.217 client @0x7fbee05126e0: udprecv 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: UDP request 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: request is not signed 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: recursion available 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: query 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: query (cache) 'isc.org/ANY/IN' approved 17-Nov-2012 12:30:58.343 client 108.162.233.15#80: send 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: sendto 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: senddone 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: next 17-Nov-2012 12:30:58.344 client 108.162.233.15#80: endrequest my question is... is this normal? should i be worried? or is this completely irrelevant to my data charges, and i should wait to see more data from bandwidthd? thank you in advance.

  • how to update the table in sql database from a Paradox DB table using delphi

    - by Sreenath Krishnakumar
    I am doing a project in Delphi6 which enables the user to update the table in SQL server database ; if there is any changes in the table of Paradox DB. An update button has been created and whenever the user clicks it, all the changes made in the paradox db table have to be updated in the SQL server table. Only if there is any changes the table need to be updated else ; it should close automatically. For that I have created a table, "Schedule" ,both in Paradox DB and SQL server. But I am stuck with this Paradox DB thing. Which component can I drop in the form for connecting the table in Paradox DB ? For SQL server I used ado table component. For this Paradox also can I use that ? I am not a regular programmer so I am not well versed this Delphi6 also. So I am seeking a help for this. Can anybody give me an example coding also ?

  • Delphi App has "No Debug Info" when Debugging

    - by James L.
    We have built an application that uses packages and components. When we debug the application, the "Event Log" in the IDE often shows the our BPLs are being loaded without debug information ("No Debug Info"). This doesn't make sense because all our packages and EXEs are built with debug. _(each project) | Options | Compiling_ [ x ] Assertions [ x ] Debug information [ x ] Local symbols Symbol reference info = "Reference info" [ ] Use debug .dcus [ x ] Use imported data references _(each project) | Options | Linking_ [ x ] Debug information Map file = Detailed We have 4 projects, all built with runtime pacakges: Core.bpl Components.bpl Plugin.bpl (uses both #1 & #2) MainApp.exe (uses #1) Problems Observed 1) Many times when we debug, the Components.bpl is loaded with debug info, but all values in the "Local Variables" window are blank. If you hover your mouse over a variable in the code, there is no popup, and Evaluate window also shows nothing (the "Result" pane is always blank). 2) Sometimes the Event Log shows "No Debug Info" for various BPLs. For instance, if we activate the Plugin.bpl project and set it's Run | Parameter's Host Application to be the MainApp.exe, and then press F9, all modules seems to load with "Has Debug Info" except for the Plugin.bpl module. When it loads, the Event Log shows "No Debug Info". However, if we close the app and immediately press F9, it will run it again without recompiling anything and this time Plugin.bpl is loaded with debug ("Has Debug Info"). Questions 1) What would cause the "Local Variables" window to not display the values? 2) Why are BPLs sometimes loaded without debug info when the BPL was complied with debug and all the debug files (dcu, map, etc.) are available?

  • Server 2012 R2 DNS Conditional forwarding not working reliably, possible caching issue?

    - by Matt
    I have a bit of a home lab setup with a domain controller that is acting as the DNS server for my network. For everything, it's working fine and forwards external DNS requests to my ISP. The household recently wanted to get Netflix going and it seemed a DNS option was better than a VPN to get around the region locking, so I signed up for unblock-us.com Since I have a Windows DNS server I thought I'd be clever and make use of conditional forwarders and added the Netflix domain to the list. Initially this worked well and all devices on the network could now access Netflix, however after about an hour going to the Netflix site would result in a page cannot be found. Doing an nslookup of Netflix.com from my PC resulted in it not returning any IP addresses. As a test, I deleted the Netflix domain from the DNS servers cache and things started working again - devices could get to the site again however the same thing happens again after around half an hour to an hour. Have I missed something here that's causing it to stop working?

  • Rtti data manipulation and consistency in Delphi 2010

    - by Coco
    Has anyone an idea, how I can make TValue using a reference to the original data? In my serialization project, I use (as suggested in XML-Serialization) a generic serializer which stores TValues in an internal tree-structure (similar to the MemberMap in the example). This member-tree should also be used to create a dynamic setup form and manipulate the data. My idea was to define a property for the Data: TDataModel <T> = class {...} private FData : TValue; function GetData : T; procedure SetData (Value : T); public property Data : T read GetData write SetData; end; The implementation of the GetData, SetData Methods: procedure TDataModel <T>.SetData (Value : T); begin FData := TValue.From <T> (Value); end; procedure TDataModel <T>.GetData : T; begin Result := FData.AsType <T>; end; Unfortunately, the TValue.From method always makes a copy of the original data. So whenever the application makes changes to the data, the DataModel is not updated and vice versa if I change my DataModel in a dynamic form, the original data is not affected. Sure I could always use the Data property before and after changing anything, but as I use lot of Rtti inside my DataModel, I do not realy want to do this anytime. Perhaps someone has a better suggestion?

  • Restart Delphi Application Programmatically

    - by Smasher
    It should not be possible to run multiple instances of my application. Therefore the project source contains: CreateMutex (nil, False, PChar (ID)); if (GetLastError = ERROR_ALREADY_EXISTS) then Halt; Now I want to restart my application programmatically. The usual way would be: AppName := PChar(Application.ExeName) ; ShellExecute(Handle,'open', AppName, nil, nil, SW_SHOWNORMAL) ; Application.Terminate; But this won't work in my case because of the mutex. Even if I release the mutex before starting the second instace it won't work because shutdown takes some time and two instance cannot run in parallel (because of common resources and other effects). Is there a way to restart an application with such characteristics? (If possible without an additional executable) Thanks in advance.

  • Using [delphi] MadExcept errorhandling with MS Echange Server 2007

    - by Tony
    I currently use madExcept.MailAsSmtpClient to send my bug reports. However a couple of large clients have upgraded to Exchange Server 2007 and we can't get the SMTP support for our app configured (the app runs on individual workstations so the messages aren't all coming from one IP. We can configure an authenticated account in exchange and access it via SMTP from other clients but it rejects madExcept for some reason). So I have two questions 1) has anyone successfully configured that combo ? or 2) is there an example somewhere of how to use the madExcept.UploadViaHTTP option?

  • How do I login once I promote my Windows Server 2012 to domain controller in my Amazon VPC?

    - by Developr
    I am following this guide: http://d36cz9buwru1tt.cloudfront.net/pdf/EC2_AD_How_to.pdf to setup my domain controller. I get AD installed correctly, but when I do the promotion to DC, the server restarts and when I try to access it, I am unable to login using any of the local system accounts. I even created my own separate user account, but that did not help. I made sure to disable the amazon settings for renaming the machine, the machine has a static ip and has been renamed.

  • Server 2012 Storage Pools, Raid Controller... can the Storage Pool deal with it?

    - by TomTom
    Before trying it out - I don't find any documentation. Given that Storage Pools have serious performance problems with parity, and do not rebalance data at the moment when you add discs, my preferred way to use them would be as think provisioned space, ISCSI targets - with every "Pool" running against 1 RAID that comes from a Raid controller (who also introduces SSD read and write caching - another thing missing from Storage Pools). The main question is - how does a Storage Pool handle the change in the underlying disc that can happen? I mostly talk about OCE (Online Capacity Expansion), where a disc after an expansion suddenly reports a larger space. Standard Windows allows you to use this additional space (and expand the partitions). How does a storage pool handle it?

  • Adding files to the DPR file vs project paths in Delphi 2010

    - by Robert McCabe
    We are just migrating from D7 to D2010 and are having a debate about cleaning up the project paths. We have a number of directories with a large number of Pas files that are included on some project paths, but only a few of the files are actually used by any single project. One option is to eliminate the project paths completely and only have all used files in the dpr. The second option is to keep only the needed files in the dpr and have project paths to the directories for the rest of the files. Is there any argument for one option over the other?

  • How to identify where (external) units are used in a Delphi XE2 project

    - by philnext
    I use JCL Project Analyser to see what units are used in my project, in order to 'clean' it. But, for big projects, I don't really see the dependencies beause I see the units names but not where they are used. I used Map file but with no success. Is there any free tool for having used units AND where they are used ? I tried GExpert Project Dependancies without succes : Example : I have JCLInifiles in Project Analyser but I don't see it in GExpert Project Dependancies.
