  • Programming Windows Cluster resource DLLs using Delphi

    - by kaeff
    I wonder whether there's a way to program a resource DLL for Windows Clusters in Delphi. I want to write a program that observes cluster state changes. Judging from the MSDN API reference, all relevant functions are located in the ClusAPI.h and ResAPI.h headers, but unfortunately it seems as if they haven't been ported yet and HeaderConv seems to fail on them. Does anyone has experience in doing such a thing?

  • Delphi, read data from 3rd party data field

    - by donaldadams1951
    I am writing an application that needs to read a data field on another Delphi program and I do not have access to the source code of the 3rd party program. The data field contains the "foreign key" to a record I need to retrieve or create in my application. I would appreciate any links to knowledge or components that will help me with my program.

  • Start two processes and connect them with a pipe in Delphi

    - by Steve
    I need to launch two external programs in my program and connect the STDOUT of the first one to the STDIN of the second program. How can you achieve this in Delphi (RAD Studio 2009, if it matters)? I'm operating in Windows environment. As a commandline command my situation would look something like this: dumpdata.exe | encrypt.exe "mydata.dat"

  • How to decrypt a string in C# that was encrypted in Delphi

    - by Simon Linder
    Hi all, we have a project written in Delphi that we want to convert to C#. Problem is that we have some passwords and settings that are encrypted and written into the registry. When we need a specified password we get it from the registry and decrypt it so we can use it. For the conversion into C# we have to do it the same way so that the application can also be used by users that have the old version and want to upgrade it. Here is the code we use to encrypt/decrypt strings in Delphi: unit uCrypt; interface function EncryptString(strPlaintext, strPassword : String) : String; function DecryptString(strEncryptedText, strPassword : String) : String; implementation uses DCPcrypt2, DCPblockciphers, DCPdes, DCPmd5; const CRYPT_KEY = '1q2w3e4r5t6z7u8'; function EncryptString(strPlaintext) : String; var cipher : TDCP_3des; strEncryptedText : String; begin if strPlaintext <> '' then begin try cipher := TDCP_3des.Create(nil); try cipher.InitStr(CRYPT_KEY, TDCP_md5); strEncryptedText := cipher.EncryptString(strPlaintext); finally cipher.Free; end; except strEncryptedText := ''; end; end; Result := strEncryptedText; end; function DecryptString(strEncryptedText) : String; var cipher : TDCP_3des; strDecryptedText : String; begin if strEncryptedText <> '' then begin try cipher := TDCP_3des.Create(nil); try cipher.InitStr(CRYPT_KEY, TDCP_md5); strDecryptedText := cipher.DecryptString(strEncryptedText); finally cipher.Free; end; except strDecryptedText := ''; end; end; Result := strDecryptedText; end; end. So for example when we want to encrypt the string asdf1234 we get the result WcOb/iKo4g8=. We now want to decrypt that string in C#. Here is what we tried to do: public static void Main(string[] args) { string Encrypted = "WcOb/iKo4g8="; string Password = "1q2w3e4r5t6z7u8"; string DecryptedString = DecryptString(Encrypted, Password); } public static string DecryptString(string Message, string Passphrase) { byte[] Results; System.Text.UTF8Encoding UTF8 = new System.Text.UTF8Encoding(); // Step 1. We hash the passphrase using MD5 // We use the MD5 hash generator as the result is a 128 bit byte array // which is a valid length for the TripleDES encoder we use below MD5CryptoServiceProvider HashProvider = new MD5CryptoServiceProvider(); byte[] TDESKey = HashProvider.ComputeHash(UTF8.GetBytes(Passphrase)); // Step 2. Create a new TripleDESCryptoServiceProvider object TripleDESCryptoServiceProvider TDESAlgorithm = new TripleDESCryptoServiceProvider(); // Step 3. Setup the decoder TDESAlgorithm.Key = TDESKey; TDESAlgorithm.Mode = CipherMode.ECB; TDESAlgorithm.Padding = PaddingMode.None; // Step 4. Convert the input string to a byte[] byte[] DataToDecrypt = Convert.FromBase64String(Message); // Step 5. Attempt to decrypt the string try { ICryptoTransform Decryptor = TDESAlgorithm.CreateDecryptor(); Results = Decryptor.TransformFinalBlock(DataToDecrypt, 0, DataToDecrypt.Length); } finally { // Clear the TripleDes and Hashprovider services of any sensitive information TDESAlgorithm.Clear(); HashProvider.Clear(); } // Step 6. Return the decrypted string in UTF8 format return UTF8.GetString(Results); } Well the result differs from the expected result. After we call DecryptString() we expect to get asdf1234but we get something else. Does anyone have an idea of how to decrypt that correctly? Thanks in advance Simon

  • What are some of the core principles needed to master Multi threading using Delphi?

    - by Gary Becks
    I am kind of new to programming in general (about 8 months with on and off in delphi and a little python here and there) and I am in the process of buying some books. I am interested in learning about concurrent programming and building multi threaded apps using Delphi. Whenever I do a search for "multithreading delphi" or "delphi multithreading tutorial" I seem to get conflicting results as some of the stuff is about using certain libraries (omnithread library) and other stuff seems to be more geared towards programmers with more experience. I have studied quite a few books on delphi and for the most part they seem to kind of skim the surface and not really go into depth on the subject. I have a friend who is a programmer (he uses c++) who recommends I learn what is actually going on with the underlying system when using threads as opposed to jumping into how to actually implement them in my programs first. On amazon.com there are quite a few books on concurrent programming but none of them seem to be made with Delphi in mind. Basically I need to know what are the main things I should be focused on learning before jumping into using threads, if I can/should attempt to learn them using books that are not specifically aimed at delphi developers (don't want to confuse myself reading books with a bunch of code examples in other languages right now) and if there are any reliable resources/books on the subject that anyone here could recommend. Thanks in advance.

  • Why 2 GB memory limit when running in 64 bit Windows ?

    - by Roland Bengtsson
    I'm a member in a team that develop a Delphi application. The memory requirements are huge. 500 MB is normal but in some cases it got out of memory exception. The memory allocated in that cases is typically between 1000 - 1700 MB. We of course want 64-bits compiler but that won't happen now (and if it happens we also must convert to unicode, but that is another story...). My question is why is there a 2 GB memory limit per process when running in a 64 bit environment. The pointer is 32 bit so I think 4 GB would be the right limit. I use Delphi 2007.

  • How make a control that look like the "download" dialog of firefox

    - by mamcx
    I have a aplication that like firefox, can be enchanced from plugins available from internet. Now, I want to provide in Delphi (2010) a dialog similar to the download from firefox. I have no skills in build graphical controls. Using the standard controls of Delphi, what could be the best way... using a TListView/TStringGrid with custom draw or... The idea is show a icon in the left, a title with subtitle with 1-3 lines on the middle and date/version on the rigth. That row must be selectable and that is all.

  • Raudus vs ExtPascal: Delphi web developement alternatives that use ExtJS

    - by user193655
    Delphi developers has several tools (several alternatives to ASP.NET) for building web applications. While No.1 framework is Intraweb, there is a lot of interest around ExtJS, that has 2 incarnations: 1) the opensource ExtPascal 2) the closedsource Raudus Now the products are different, Raudus never supports the latest ExtJS version (while ExtPascal does because as far as I read it "almost automatically updates itself to the latest ExJS version"), Raudus "seems" much RAD (much similar to Intraweb from the RAD point of view). Anyway why chose one or the other? Why Raudus (since it is free) cannot become Open Source? Or does Raudus use ExtPascal behind the scenes?

  • Delphi: Get MAC of Router

    - by Daniel Marschall
    Hello, I am using Delphi and I want to determinate the physical MAC address of a network device in my network, in this case the Router itself. My code: var idsnmp: tidsnmp; val:string; begin idsnmp := tidsnmp.create; try idsnmp.QuickSend('.1.3.6.1.2.1.4.22.1.2', 'public', '10.0.0.1', val); showmessage(val); finally idsnmp.free; end; end; where 10.0.0.1 is my router. Alas, QuickSend does always send "Connection reset by peer #10054". I tried to modify the MIB-OID and I also tried the IP 127.0.0.1 which connection should never fail. I did not find any useable Tutorials about TIdSNMP at Google. :-( Regards Daniel Marschall

  • Delphi connection to OpenEdge Progress-4GL Database

    - by Cesar Marrero
    Folks: Has anyone had success connecting to a Progress-4GL database with Delphi?   I've been unable to establish any connection with the ODBC driver provided by the vendor (Progress OpenEdge 10.1C Driver). I've entered (what I believe are) the right parameters, but keep on getting an error whenever I test the connection: "[DataDirect][ODBC Progress OpenEdge Wire Protocol driver] Socket closed." Background: I've been tasked to re-design a 13-year-old application, but the original programmer did not provide any supporting documents, passwords, configuration setup, etc. (I'm on my own)!   To make things worse, online help and useful documentation about Progress is scarce (I had never heard about this database until now). I want to examine the existing data, maybe create an ERD to familiarize myself with the schema, but I can't even access the data outside of the OpenEdge code. Any help is appreciated!

  • Breakpoints not working in Delphi 6 DirectShow source filter

    - by Robert Oschler
    I'm trying to debug my DirectShow source filter. I'm using Delphi Pro 6 on Windows XP along with the DSPACK component library. I'm using Skype as my host application, which I set in the Parameters option in the Run menu, for testing my source filter DLL (ax file extension). Skype runs fine and I see a stream of my OutputDebugString messages in the Event Viewer, but none of my breakpoints are ever hit. In my Project Settings I have optimizations off, stack frames on, debug DCUs on, Range Checking on, and Overflow checking on. Each time I modify my code and run a test I: Do a full build Unregister the DirectShow filter (regsvr32 /u) Register the DirectShow filter (regsvr32) Run Skype as my Host application from the IDE When an Exception occurs, the IDE does trap it and pops up an error dialog box with the option to view the assembler code in the CPU window. However none of my breakpoints are being hit. Can anyone tell me how to get breakpoints working? Thanks.

  • Delphi 2010 buttons losing click event

    - by Lobuno
    I've been experimenting a quite strange problem using Delphi 2010. In one form (a quite complex one) some buttons are automagically losing the click event. I am not dynamically assigning the event or something (they are wired in IDE). The events are fired OK some times but suddenly (and randomly) some of them don't fire the events anymore. Placing a break point in the event doesn't stop the execution. Weird, yes, and I'm lost. I know there is no explanation for this so I only want to ask if there is anybody else experimenting the same problem.

  • JNA-Mapping Delphi Function

    - by Florian
    Hi! How do i map this function with JNA: Delphi code: function getData(InData1: PChar; InData2: PChar; Data: TArray16; var OutData1: PChar; var OutData2: PChar): integer; stdcall; with: TArray16 = array[0..15] of char; The int value that is returned can be 0 for Error or 1 for right execution; My suggestion is: Java code: int getData(String inData1, String inData2, byte[] data, byte[] outData1 byte[] outData2); The problem is that the function of the dll returns 0. I also tried other Datatypes, but it hasn't worked jet. I think the problem is that the dll function can't write to the parameters outData1 and outData2. Who can help me?....Thanks!!

  • Web serivce time out errors in delphi

    - by JD
    Hi, I have a client application that makes SOAP requests. I have set the timeout to 20 minutes. However, sometimes I see the timeout error occurring after 10 seconds. I have the following in code: RIO.HTTPWebNode.ReceiveTimeout := 1200000 Do I need to set the ConnectTimeout and SendTimeOut? Currently they are set to the default values of 0. What difference would setting these make? I am using Delphi 2007. Looking further at the error message I see I get "The operation timed out....". So should I be setting my ReceiveTimeOut to zero since I really do not want any timeout at all?

  • Delphi 2009 RAD Studio - Desktop Selector not Working

    - by Andreas Rejbrand
    In the Delphi 2009 RAD Studio, there is a drop-down combo box where you can select the desktop configuration, i.e. "Default Layout", "Debug Layout, "Classic Undocked", etc. This has stopped working for me, i.e. when I select a desktop, nothing happens. I think I once "customized" the toolbar, by removing the drop-down combo box, and then I added it again, and ever since it has been dead. Is this a known bug? Is there a cure?
