Re: Missing ShFolder.h and ShFolder.lib Masaaki Onishi10-Oct-01 6:33 Masaaki Onishi 10-Oct-01 6:33  Hello, the codegurus around the world.;) Probably, you need Microsoft Platform SDK.

I'm usinge these API on a function that will merge multiple files into one file. The problem is that any nul(0x00) character will be converted (after WriteFile() call) to sp(0x20). I've used a 'BYTE buf[4096]' buffer to load into datas and also changed this buffer to an 'LPVOID lpbuf' dinamicaly allocated with (HeapAlloc() function), but never changed. Can anyone tell me my these conversions? What I'm doing so wrong? thank you in advance. "Take time to think, it is the source of power" Re: Characters conversions on ReadFile and WriteFile Erik G. Poel10-Oct-01 6:02 Erik G. Poel 10-Oct-01 6:02  I believe you have to open the FILE stream as binary.(if you are not all ready doing that) That way everything is treated as raw binary data. erik Re: Characters conversions on ReadFile and WriteFile MAXS72U10-Oct-01 20:27 MAXS72U 10-Oct-01 20:27  Correct, but I opens all files with CreateFile(...) API call. How can I specify binary mode instead of text mode?

First time, I use mciSendString () to do this, and this works fine. But, QA pointed out that this code didn't work on Windows 95 and NT without installing MCI. So, I use DeviceIoControl function since I found some sample code for Windows 9x and NT. However, since I'm lazy , I omitted the code to check if the other application uses CD or lock and unlock CD. Without these codes, my code works fine on Windows OS including Windows XP. But, I'm curious that we need these kind of codes - check if the application uses CD or lock or unlock CD. (In fact, the time of executing my code rarely faces these kinds of situation, so I omitted these.)

NormDroid10-Oct-01 2:49 NormDroid 10-Oct-01 2:49  Not for the faint hearted. I recently changed the way my project was designed and parts of it stopped working, I tracked this down to a media com object being created in my worker thread and not the thread where my *mainframe* window resides. Question? If I'm in a worker thread is there anyway to create a com object under the context of another thread i.e the thread where my mainframe resides, I'm sure I've done this before, but have'nt touched COM for 6months. Thanks In Advance Norm Almond Chief Technical Architect FS Walker Hughes Limited Re: Creating a COM object in another thread? 10-Oct-01 3:12 10-Oct-01 3:12  Does the com object work in a worker thread (does it have a window or need a message pump)? You may need to create it in your main thread or a user-interface thread instead. If you create a com object from the worker thread, then it cannot be called from other threads directly because the com implemenation uses windows messages to call objects in other threads. Re: Creating a COM object in another thread?

Ideally I *dont* the DoEvents code, the the object needs to be create in the ActionThread code. Norm Almond Chief Technical Architect FS Walker Hughes Limited Re: Creating a COM object in another thread? 10-Oct-01 3:53 10-Oct-01 3:53  if I put DoEvents( PeekMessage etc) in the while (1) loop is works fine. That means you DO need to have a message pump for the object to work. Why not change the ActionThread to a user interface thread derived from CWinThread so that you don't need to DoEvents explicitly. Re: Creating a COM object in another thread? NormDroid10-Oct-01 3:59 NormDroid 10-Oct-01 3:59  Owwww noooo, can't do that. Need especially CWinThread (horrid) need to keep the object in a worker thread. I think I have a solution see other postings on this thread.

NormDroid10-Oct-01 4:16 NormDroid 10-Oct-01 4:16  Got it working, do you won't a copy for reference Norm Almond Chief Technical Architect FS Walker Hughes Limited Re: Creating a COM object in another thread? 10-Oct-01 4:41 10-Oct-01 4:41  No, thanks. But you did move the creation of your com object to the main thread which has a message pump, right? Otherwise, you need to write an article to explain how it is working. Re: Creating a COM object in another thread? Not Active10-Oct-01 3:20 Not Active 10-Oct-01 3:20  You can create the object and then marshal it to the other thread via CoMarshalInterThreadInterfaceInStream.

BTW: calling CRuntimeClass::CreateObject makes absolutely no sense when you know the exact type of object - in your case, it's CHScrollTitle. You can just write t = new CHScrollTitle; Tomasz Sowinski -- http://www.shooltz.com
