Java control in Windows app? Paul Vickery13-Jul-04 2:45 Paul Vickery 13-Jul-04 2:45  I have been asked to see if I can use a Java control from within an MFC app. I don't know enough Java to know if this is possible. The control I am trying to hook in is the thinkmap control (http://www.thinkmap.com[^]) Does anyone have any idea of whether this is possible, and if so, how I would go about doing it?

V.13-Jul-04 2:49 V. 13-Jul-04 2:49  You can port Java code to C++ if that's what you mean. I think it's called JRI but I'm not sure. I have no experience myself though. Hope it helps!

Therefore you are not going to be able to just "use" a Java component in a Win32 application since there is no JVM context. After that there is a multitude of possibilities.

Enyway thanks, Bikram Singh. Maybe you or somebody else know how to solve my problem with pdf document? Good luck! Re: pdf: CMYK and RGB bikram singh13-Jul-04 22:00 bikram singh 13-Jul-04 22:00  Well, pass in the RGB values and u get the CMYK values back. I dont know about PDF conversion, but the Adobe site does have the PDF specs i think...check that out Bikram Singh Network install Monty213-Jul-04 2:37 Monty2 13-Jul-04 2:37  Norton antivirus's corporate version automatically discovers all the clients when installed on the server and THEN AUTOMATICALLY INSTALLS A client version of antivirus on the remote system How does it do that ? All the users and their IP address can be found out i guess , but how can it install on the remote machine ?

This client will download any new updates, and install them itself. Re: Network install David Crow13-Jul-04 4:51 David Crow 13-Jul-04 4:51  mailMonty wrote: How does it do that ? My guess is with RPC. Remote Task Manager works in a similar fashion. When connecting to a remote machine, if it detects that the remote machine does not have the RTM service installed and running, it will install and start the service, and then connect. It is very seamless.

The file saves/plays fine. mciSendString("open new type waveaudio alias current wait", 0, 0, 0); mciSendString("set current format tag pcm bitspersample 16 channels 1 samplespersec 44100 wait", 0, 0, 0); mciSendString("record current from 0 overwrite", 0, 0, 0); . . . if(m_saveFile.DoModal() == IDOK) { CString saveFile = "save current "+ m_saveFile.GetPathName() + " wait"; mciSendString(saveFile, 0, 0, 0); mciSendString("close current wait", 0, 0, 0); when i open the file and query the time format it returns "milliseconds", but the time it gives me (querying length) is usually about ten times what it actually is. The application gives the correct length of pre-saved files..... ring any bells?

I saw many appliction on Codeproject ,, but no one is of mine kind help I have a slider in it ,, to move the video postion same as in Windows Media Player. I m Using MCI Api's .... Slider Control only Gives three Message Handlers 1. CustomDraw (..........) 2, OutofMemory(..............) 3. ReleasedCapture(...) Which one i Should use..

Re: How to handle a Slider Control Zeeshan Bilal13-Jul-04 2:18 Zeeshan Bilal 13-Jul-04 2:18  I m not Capturiong the Slider's THumb. HAve u any Sample.. plz send at zahid_ash@yahoo.com thanx Re: How to handle a Slider Control gmn13-Jul-04 2:38 gmn 13-Jul-04 2:38  this isnt an actual block of code as such, just bits pasted together to illustrate the point.... void CSPlayerDlg::OnReleasedcapturePosSlider(NMHDR* pNMHDR, LRESULT* pResult) { nextPos = m_position.GetPos() mciSendString("play current from 0 notify",0 ,0, this->GetSafeHwnd()); } you'd want to play from m_position.GetPos(), not from zero, you'll have to format the string appropriately.... you also want to set the slider range to the length of the file your playing.

But on runtime i'm getting error when i call the DoModal on the DLL side. This is happening for both MFC DLL Depended Host Application as well as the Win32 Host Application . The Code is like this //on the DLL Side extern "C" void __declspec(dllexport) TestFunction(); void TestFunction() { AFX_MANAGE_STATE(AfxGetStaticModuleState()); CMyDialog dlg; dlg.DoModal(); } //On the Caller Side extern "C" void __declspec(dllimport) TestFunction(); void CMyTestApp::OnAppAbout() { TestFunction(); } Please Help Me... ! Kind regards, Subbi. Re: Problem Exporting the Modal Dialog from a Regular MFC DLL ThatsAlok13-Jul-04 2:08 ThatsAlok 13-Jul-04 2:08  Madame,With all due Respect, Basiclly i never head of exporting class from MFC Regular DLL. i think only MFC Extention DLL provide support for exporting class. in my opinion,You create a MFCExtention DLL and then try to export Model Dilg class. don't remeber to precede the DLg className with AFX_EXT_CLASS macro,then only you able to export it ----------------------------- "I Think It will Work" ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk Re: Problem Exporting the Modal Dialog from a Regular MFC DLL SriSubbu13-Jul-04 2:14 SriSubbu 13-Jul-04 2:14  Hi Alok, I think you have understood the problem not clearly. I'm creating a MFC Regular dll not a MFC Extention DLL as first. Further What i'm trying to export is a C++ Function rather than the MFC Dialog Class (the TestFunction in this case). The Problem is whenever i try to call the Modal Dialog the Application breaks. Kind regards, Subramanian Iyer. Re: Problem Exporting the Modal Dialog from a Regular MFC DLL ThatsAlok13-Jul-04 2:35 ThatsAlok 13-Jul-04 2:35  Soory Again,Madame. previously i think you want to export Dialog in your Main Application,that why i suggest you MFC Extention DLL because i am successfull in exporting Dialog Class using MFC . but i think you want to create Regular dll that can show Dialog.,ok pls tell me is you seeing any error or assertion call,if yes pls send me the error code. ----------------------------- "I Think It will Work" ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk Re: Problem Exporting the Modal Dialog from a Regular MFC DLL SriSubbu13-Jul-04 3:43 SriSubbu 13-Jul-04 3:43  Hi Alok, I've my application break at the point when it tries to run the modal loop I've the call Stack goes like that Call stack: CWnd::RunModalLoop(unsigned long 4) line 3478 + 11 bytes CDialog::DoModal() line 536 + 12 bytes InvokeModalDialog(HWND__ * 0x003d0290) line 72 And it seems that line 3478 of Wincore.cpp is calling the AfxGetThread() Which is returning NULL. I thnink it will give you a clear picture... Kind Regards, Subbi. Re: Problem Exporting the Modal Dialog from a Regular MFC DLL bikram singh13-Jul-04 4:37 bikram singh 13-Jul-04 4:37  Hi, I see no reason why your code should fail, under normal circumstances. Infact, I tried your code (dll+exe side), and it compiles and runs perfectly well. Something other than your test code could be causing the problem. It would help if you specified what else you are doing. Bikram Singh Re: Problem Exporting the Modal Dialog from a Regular MFC DLL SriSubbu13-Jul-04 5:45 SriSubbu 13-Jul-04 5:45  Hi Bikram, Is it possible for you, can you kindly send me Your Test Application to me, so that i can find out the problem in my code. Even one of my other friend tried the same, even he got the same result. Kind regards, Subbi. Re: Problem Exporting the Modal Dialog from a Regular MFC DLL bikram singh13-Jul-04 6:22 bikram singh 13-Jul-04 6:22  sure. i'll email it to you. Bikram Singh Re: Problem Exporting the Modal Dialog from a Regular MFC DLL SriSubbu13-Jul-04 10:50 SriSubbu 13-Jul-04 10:50  Bikram, Really Thank You so much for your code. I found the Problem with my code. Actually I've created a Win32 DLL thru' the Application wizard first and then I set the property to use MFC in Shared Dialog. So, i've no CWinApp Object Created, rather i've only the DLLMain function in the Application, which leads to the failure of the Application call by which i get a NULL pointer, of the AfxGetApp call in the RunModalLoop function. Again I thank you for your help. Kind Regards, Subbi.
