Hi everyone,
my app should update a listcontrol inside a while statement, but the data are shown only at the end of the whole function, when the app gets the idle state. Furthermore, all the buttons can't be pressed until the end of the function. Can somenone explain me the way to work with it?
Thanks
Vilmer

try putting a call to Sleep() for a few milliseconds in your while loop, or make the function static and use AfxBeginThread() to call the function.
If I write code in my sleep, does that make me brilliant, or just a lazy programmer?

It sounds like you would benefit from a separate thread that updates the list control. This would allow the GUI to remain responsive to button clicks and repainting.

Yeah, you hit the problem.
But the items of the listcontrol are related to some data which change in the while loop. If I use threads, the data taken from any thread won't be correct, because the while statement continue its run, not taking care of the threads execution.
My question is: is there any way to create a (or more) thread which can use dynamic data which depend on something outside the thread? I know that threads can refer to a pointer to parent, and they can use its member variables, but there's no way for me to make that data useful, because they change always.

I was thinking more of having the whole function with the while loop in it be executed through a thread. Then there's 3 choices I can think of:
1. send a pointer to your parent class's instance, and access its variables through this pointer.
2. send a pointer to your parent class's instance, then make the variables/values that will be changing static members of the parent class
3. make the variables/values global

I'll show you an example of how my code works:
CListCtrl myLC;
int Num; (as members of CMyClass)
void CMyClass::OnButtonStart()
{
Num = 0;
char* ptrItem;
while (Num < 100)
{
itoa(Num,ptrItem,10);
myLC.InsertItem(Num,ptrItem);
Num++;
}
}
If I use AfxBeginThread(MyThread,this) - where MyThread provides only the InsertItem statement - inside the while statement and then refer to a CMyClass instance, that instance show a value of Num which is already 100, beacause the while statement doesn't wait for the thread to finish its execution.
Aaarrgggghhhh

I was thinking more along the lines of this:
void CMyClass::OnButtonStart()
{
AfxBeginThread(FillListView,this);
}
UINT ListView(* pClass) :zzz:
{
CMyClass* pMyClass = (CMyClass*)pClass;
pClass->Num = 0;
char* ptrItem;
while (pClass->Num < 100)
{
itoa(pClass->Num,ptrItem,10);
pClass->myLC.InsertItem(Num,ptrItem);
pClass->Num++;
}
return 0;
}
the syntax may be a little off since I'm doing it out of my head, but I think you should be able to follow what I'm saying. I hope this helps in any way.

Hi guyz !
I want to develop a c++ application with speech recognition using visual studio .net 2003 and microsoft speech .net sdk beta 4.0 v.1.0. I've been looking over the documentation and tutorials for the speech sdk but they all seem to be for c# and visual basic applications and only for web applications. If anyone has some sample code that could help me get started I would be most greatful.
Thanx
Nina

There's a few functions you'll need. WNetOpenEnum, followed by repeated calls to WNetEnumResource, and finally WNetCloseEnum. Note that these functions will not give you the whole network in one go - they only give you one "level", and you'll need to recurse down to build up a picture of the entire network.

Anyone knows a foolproof method to retrieve the paths to the .pst files for a given Microsoft Outlook profile ?
I know where it is stored by default.However I am looking for something which will retrieve the paths even of the user chooses to save the .pst file to a custom location.
Thanks .

Hi,
if you mean to search a file just like using the Search tool of Win32, you can use the functions _findfirst and _findnext to search for all .pst on your hard drive.
See also http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt__findfirst.2c_._findfirsti64.2c_._wfindfirst.2c_._wfindfirsti64.asp

Well guys, sorry for confusing things up, Searching for files won't do because i also wish to know which .pst file belongs to which profile.
Thanks david for ur solution, i am gonna try that one out 
also any additional question that popped in my mind..using MAPI we can create new PST services for a profile, so now say a profile has 3 .pst files linked to it.Where will the mails be downloaded ? any idea ?
thanks for the replies in advance..

There's an option to set this in Outlook/Outlook Express. I'm not sure how you'd get access to this option - probably through the registry somewhere.

As far as I know, you can't. You have to have a title bar to have a system menu.

Hello Friends,
I am having a rich edit control in which I am displaying some 10-15 lines of text. My problem is that Whenever I want to display the contents of the rich edit control on double click, it's not displaying. When I tried to debug I found that the double click message handler is not getting called. When I disabled the control then the double click is working but I am not able to scroll the text.
Please help me.
Thanking you in advance.
Neelesh K J Jain.

Have you called AfxInitRichEdit()?

How does it not compile? Some compiler error messages would be useful.
|
|
|
|

I'm pretty sure you should be able to do this, cause I've some projects that do just what you describe. However one of the gotcha's is that numerous compiler settings need to be exactly the same for each of the projects. Eg. 'Use MFC in a Shared DLL', the same run-time library, struct member alignment, possibly even some of the C++ runtime type information.
I've got one DLL project with a class that inherits from CDocument. In another DLL project, there exists a class that inherits from the class implemented in the other DLL and each of the classes have message maps.
As the other poster suggested, if you post what compile errors you get, it might help some.

Using Visual C++ 6.0
I'm working on a project that contains 26 extension DLLs. In one of the extension DLL's, we have a class that inherits from CWnd called CWndA, and another class that inherits from CWndA called CWndB. (The real names aren't importnant, I just figured it would make it easier to talk about if I gave these names in the example.)
Both CWndA and CWndB have message map macros in them. HOWEVER, if I try to inherit from either CWndA or CWndB in another DLL or EXE file, I can't have a message map because the program simply won't compile.
This is true with any class that has the AfxMessageMap macro in it.
Can someone tell me why as well as if there's a way to fix it?

Dear Friends,
I know i am asking very simple question, so please reply to ASAP and help me to get the solution.
Please write to me how to get the image of a dialog box as a .bmp or any kind of image file. I just want to get the image of dialog box so can display the complete contents of dialog box items i.e. buttons etc for documentation.
Please respond ASAP. For this I shall ever be greaful to you.
Although it is possible by creating such an option inside the dialog box or by adding menu to provide copying option but I think it is possible in other way too and that method I wish to know....Thus please write to me to get the solution......................
Thanking you in advance...................
