Structure posting yamini20-Apr-01 0:34 yamini 20-Apr-01 0:34  Hi all, I am trying to post a structure to a Created Worker Thread !All the members of the structure are BSTRs.I am defining all the members of the structure & posting the structure as the WPARAM of PostThreadMessage.(I am typecasting the pointer to structure as WPARAM). The problem is I am able to post the structure with all the member values correctly !But while getting that Thread Message & retrieving the values of the members some of the Member values r received wrongly !I have used SysAllocString while getting back the values of members ! How can I rectify the problem ! Thanx! Y.Yamini Devi Re: Structure posting Jeff Naber20-Apr-01 8:43 Jeff Naber 20-Apr-01 8:43  Yamini, It sounds like you are passing in a pointer to the structure properly, and some of the data is correct. But since the interface thread is still running, perhaps the values that were originally stored in the structure have been changed before you got a chance to read them? (Just a side note to be sure that you use a Critical Section or a Mutex to ensure that one thread is not writing new data to the structure at the same time the other is trying to read it.) I'm assuming that you do cast the WPARAM back to the correct structure pointer when the message is received by the worker thread. If checking on this stuff doesn't help, reply to the post, and I'll try to think of other reasons this may be happening. Jeff Re: Structure posting Jeff Naber23-Apr-01 5:14 Jeff Naber 23-Apr-01 5:14  I got the following message in reply: Thanx for the ideas !I created a worker thread .I am posting message to this worker thread only ! As you said I am passing the pointer to structure as WPARAM of the message !Now, in the ThreadProc of this worker thread I am typecasting the WPARAM of the message to the structure pointer and retrieve the members of the structure !Here only I am receiving the wrong value for some data members(Of the 11 members the last 4 member values are wrong !)What can be the problem ?I had tried with Mutex & critical section.Still the same problem exists ! How can I overcome this problem ? Regards, Y.Yamini Devi Re: Structure posting Jeff Naber23-Apr-01 5:21 Jeff Naber 23-Apr-01 5:21  Yamini, It depends on how you know the members are wrong. If you are using a byte index into the structure and coming up with the wrong values, or if you are looking into memory locations directly, then the problem may be how the structure is defined. If you don't tell the compiler to pack the structure to 1 byte values then when it builds the structure it may pad spaces onto the end of intermediate values to get the 'correct' block sizes. If you have strutures within the defined 'communication' structure, this problem can be compounded. Check that you use the compiler directive "#pragma pack (1)" around your structures to be sure that the compiler is not adding additional empty bytes. Once all the structures are defined you can use "#pragma pack ()" to return the pack value to its previous setting. Just a thought Jeff How to get the handles of all child windows 19-Apr-01 23:59 19-Apr-01 23:59  Hi, does anyone knows how I can get the handles to all child-windows of the Active or Foreground window? In WINDOWS CE! I know there is an API call EnumChildWindows, which work perfecly on the desktop, but is not supported on CE... (PocketPC) Is there an other way to do this? Greetings Kasper how can I get the Kana mode of Japanese IME AlexMin19-Apr-01 16:07 AlexMin 19-Apr-01 16:07  Now ,I have a question to cancel the Kana mode of Japanese IME,So I think must get current Kana mode,but how can I get it? use witch IME API to get it ? Thank you ! Re: how can I get the Kana mode of Japanese IME Masaaki Onishi22-Apr-01 15:06 Masaaki Onishi 22-Apr-01 15:06  Hello, the codegurus around the world.;) Taking off and on IME may be easier to change the input type. That is, if IME is on, the default input type is Kana. If IME is off, the default input type is the direct input type like A-Z or number. Check ImmGetContext, ImmGetOpenStatus, and ImmSetOpenStatus API function and some sample code of IME in MSDN help to take on and off IME. If you want to get the exact input type, we may have some code and assgin the exact input type which we want. But, so far, I have not succeeded this yet. Have a nice day! -Masaaki Onishi- Date/Time problem. Henrik19-Apr-01 13:43 Henrik 19-Apr-01 13:43  Hello, I got a major issue with trying to set DATE on files, not TIME, that works flawless. Here's the way I did: void CDialogAttribs::DoDataExchange(CDataExchange *pDX) { ... DDX_DateTimeCtrl(pDX, IDC_ATTR_DATE, m_tmeDate); // m_tmeDate is a CTime; IDC_ATTR_DATE is a "caleneder" control created in resource ... } { ...

That should get you started. Steve What Include File Ghasrfakhri20-Apr-01 2:43 Ghasrfakhri 20-Apr-01 2:43  Hi Steve.

The code goes like this . STARTUPINFO suinfo; memset(&suinfo,0,sizeof(suinfo)); PROCESS_INFORMATION procinfo; BOOL result; for(int i=0;i<10;i++) { result=CreateProcess("<path of="" yr="" exe="">","",0,0,FALSE,NORMAL_PRIORITY_CLASS,0,0,&suinfo,&procinfo); if(result) { cout<<"Client process created\n"; } else { cout<<"Failed to create the client process\n"; exit(0); } } This will work !

When I do this it works fine but I want to set these from the code because i won't have to remember them all the time. I did this void CXXXCombo::PreSubclassWindow() { ModifyStyle (0,CBS_OWNERDRAWVARIABLE|CBS_HASSTRINGS); CComboBox::PreSubclassWindow (); } it did not work. Why ? How can i set these from the code by subclassing a combobox Thanks. Re: CComboBox Drake Elsari19-Apr-01 12:00 Drake Elsari 19-Apr-01 12:00  Ok, now i'm kinda a beginner but, I think you need to use GetStyle and then or(|) the other to style bits on top of the getstyle return.
