Re: Is this a secret? (mixing native code with windows forms)

8-Nov-04 4:21

I'm putting this here because I've posted it in the managed C++ forum a couple of times, and I haven't gotten an answer yet.

I have a very good book (except for this one thing) by Tom Archer,"Extending MFC Applications with the .Net framework" and "Visual C++.Net Bible" by the same author, and also "Visual C++ .Net - Step by Step" by Microsoft.

Is there a way to build a mixed (native + managed) that starts off with a CFormView, and then call a windows form that I've created? There's examples for using a windows form if it's the startup form, but not if it's a second form called from an mfc class. Does ANYBODY know how to do this?

If I write code in my sleep, does that make me brilliant, or just a lazy programmer?

Probably you won't get it here, too.

I have a SDI Visual C++ program. It has 1 child window with the title bar... containing the minimize, maximize, and X for closing the Window. I DO NOT want this title bar to be loaded as part of the window when the program starts up. How can someone tell me how to do this?

Thanks.

modify the createstruct parameter in the CMainFrame class's OnCreate() member function. I don't know the exact styles off the top of my head, but you'll want to change the styles with the 'window styles' constants. (the ones that begin with WS_), like WS_THICKFRAME,WS_MINIMIZE, etc.

I have a need to put together a simple installation that will run from the users CD ROM drive. I have 2 Visual C++ applications that would be installed on a users machine...a few dlls and I need to register an Active X control also at install time. Can someone help me with this? It does not need to be anything fancy. Just a simple installation program that works.

Thanks.

I use Inno Setup freeware, very easy to use and I think it will install an active x control for you, check the features page.

Update Listcontrol

vilmer8-Nov-04 3:34

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

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.

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.

Eek! | :eek:

I was thinking more along the lines of this:

void CMyClass::OnButtonStart()
{
  AfxBeginThread(FillListView,this);  
}




UINT ListView(* pClass)  //forgot how the function declaration has to be: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

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.

Getting paths to the.pst files

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 Smile | :)

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..
