Re: Long Running CGI Application Dave_Schneider15-Mar-04 9:31 Dave_Schneider 15-Mar-04 9:31  Thanks for the responses. I'm new to the whole multi-process/multi-thread thing. So I can start another instances of my program by calling CreateProcess(), and then quit the original process without affecting my new process? The reason it takes longer then 6-7 minutes to get a response is I am generating more then one thumbnail. My program takes a directory of pictures and looks to see if there are thumbnails for each one. If no thumbnails are found, it generates them. My problem comes when a new directory has several hundred pictures. Re: Long Running CGI Application basementman15-Mar-04 9:42 basementman 15-Mar-04 9:42  Are you creating a bitmap for each thumbnail or simply copying the thumbnails onto one large image? Also, what method are you using to generate the thumbnails? If you call CreateProcess and do not specify an owning process, then that process is independent. FYI: CGI programs are typically not very scalable. You should use ISAPI or a C++ app server like this one [^].  onwards and upwards...  Re: Long Running CGI Application Dave_Schneider15-Mar-04 10:37 Dave_Schneider 15-Mar-04 10:37  I'm taking JPEG's of sizes ranging from 200kb-400kb (1280x960) and doing a down-sample on them to 2kb-4kb (200x150) JPEG's. I'm using the DevIL image library to do the work. Because I want to get as much detail as I can in these thumbnails, I an using a slower down-sampler. I'm interested in looking more at your suggestion of using a ISAPI or a C++ app server, but your link did not seem to work. Thanks.

This happens, when I unload a DLL file from my program. If I override PostNcDestroy or DestroyWindow (I should free memory there) the 2 functions never get called. The dll has a dialog interface in it, and I should clean-up the memory since the dialog is no-modal, and there is dynamically allocated memory also for strings which I display in ListView. All should work fine, but PostNcDestroy and/or Destroy Window never get called. All I get is the above metioned warning in debug mode. And because of not getting these messages, I'cant free the memory and I get memory leaks. Anyone had the same problem? Thanks in advance, D. Re: Destructor errors GDavy15-Mar-04 3:31 GDavy 15-Mar-04 3:31  make sure your functions are declared as virtual! Re: Destructor errors Deian15-Mar-04 3:34 Deian 15-Mar-04 3:34  Yes, they are declared as virtual Re: Destructor errors Ravi Bhavnani15-Mar-04 3:55 Ravi Bhavnani 15-Mar-04 3:55  [Edited] When your modeless dialog closes, it should do this: DestroyWindow(); delete this; /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: Destructor errors Deian15-Mar-04 4:17 Deian 15-Mar-04 4:17  Thanks for the comment Ravi, I know that I have to call DestroyWindow() and delete this in my modeless dialog, but the problem is that I don'get notified about it, I get the warning, and my handlers are not called, the modeless dialog is contained within a DLL file, and when it's unloaded, the warning is displayed in the debugger, the handlers are not called, and I get the memory leaks. Re: Destructor errors Ravi Bhavnani15-Mar-04 6:49 Ravi Bhavnani 15-Mar-04 6:49  Ah. Perhaps you could destruct the dialog (in an orderly manner by calling a public method that cleans up properly) when your DLL unloads? Your DLL will get notified when it's about to be unloaded. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: Destructor errors Prakash Nadar15-Mar-04 6:02 Prakash Nadar 15-Mar-04 6:02  Over ride the OnCancel, OnOk event and call destroywindow and dont call the baseclass implementation. If you calling EndDialog any where remove them and replace it with destroywindow.

How can I do that? it's mean that there are some string stored in database. When the application initalisation. some (datatype) variables should be created as public use. Regards, Anson Tong Re: Some trouble on creating public variable Prakash Nadar15-Mar-04 5:50 Prakash Nadar 15-Mar-04 5:50  I dont think that is possible under c/c++ i.e dynamically creating public variables... Well you can have a list and add all the values to the list... each index humm, can be called as the dynamically created variable but its not. The variable type of each index will be same.

I don't want to use Managed code if I don't have to. I've looked at the MS Soap Toolkit v3 and it looks like it will work, but its being deprecated later this year. Does that matter? What does anyone else use? Ta, Dave. Re: Calling SOAP Web Service from Unmanaged C++ Nemanja Trifunovic15-Mar-04 5:15 Nemanja Trifunovic 15-Mar-04 5:15  I usually use ATL Server library[^] (I know, the name is very bad) for that purpose. Also, you can look at some 3rd party solution, such as gSoap[^]. Re: Calling SOAP Web Service from Unmanaged C++ David Salter15-Mar-04 6:39 David Salter 15-Mar-04 6:39  Thanks. The ATL stuff looks cool - I'll give it a try. I tried adding a web reference into a unmanaged C++ app and Visual Studio gave me loads of "Internal Error" messages boxes and seemed to break my project. Have you ever seen that one? I'm trying to access an Apache Axis (Java) web service btw. Ta, Dave. CFormView::OnInitialUpdate() Neha15-Mar-04 1:35 Neha 15-Mar-04 1:35  Hi, I have a code as below: Class x: public CFormView { public: virtual void OnInitialUpdate(); } Class y: Public X { public: Virtual void OnInitialUpdate(); } Class z: class y { public: void OnInitialUpdate(); } When I call OnInitialUpdate () for class z it throws an exception at CFormView::OnInitialUpdate() of Class x. Could any one please help me? Regards Neha Re: CFormView::OnInitialUpdate() Prakash Nadar15-Mar-04 3:00 Prakash Nadar 15-Mar-04 3:00  OnInitialUpdate is not called by you i suppose. It is called automatically when you create the Formview using create.

I was thinking about inplementing it using rectangles? Each of the seven down will be a different music note but the 15 along will be the same as the first one in the line all the way along. So that when i press a note i can play a tune. What i need it to do is save the buttons i press somehow and then i have a button for playback. Any Ideas Re: Music Sequencer Maximilien15-Mar-04 2:54 Maximilien 15-Mar-04 2:54  mavgoose wrote: I was thinking about inplementing it using rectangles? May be simpler to implement this as an "array" of owner draw CButton; you can then use MFC messages to handle the triggering of the note.

If you're calling TrackPopupMenu, you're passing it in anyway! You can trap WM_MENUSELECT, I believe, and it should be the lParam passed. Steve S
