Show the code that has the problem, and the exact error message(s).

The error message implies that you are calling a function that expected a uint32_t so check the function signature of every function you are calling.
I don't understand why nearly everyone that posts a question omits pertinent information. It would really help if you posted relevant code and error messages.

Thanks, it's a big project,
i found the issue,
new 1 (33 hits)
XXX_Global.h: error: conflicting types for 'uint32_t'
Line 17: typedef unsigned int uint32_t;
gcc-6.3-arm32-eabi\arm-none-eabi\include\sys\_stdint.h:48:20: note: previous declaration of 'uint32_t' was here
Line 24: typedef __uint32_t uint32_t ;
there are 2 tyepdef uint32_t

I'm happy to see you made progress. It's unusual to ask this type of basic question, you should change the variable type on those function calls to uint32_t and recompile.
It would be great if you revealed the source code. You are forcing anyone that assists you to speculate.

Then remove the one from XXX_Global.h.

Hi
I have the following collection class (referencing a struct) which is causing the complier error listed below
I ended writing my own link list becuase I couldnt resolve the issue however I am hoping that by posting this someone can maybe explain it to me
so here is the code
listed below is the complier error for some reason the complier doesnt like a Clist template in a struct
C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Tools\MSVC\14.29.30133\atlmfc\include\afxtempl.h(954,17): error C2280: 'CStorge::buildcombo::tcbholder &CStorge::buildcombo::tcbholder::operator =(const CStorge::buildcombo::tcbholder &)': attempting to reference a deleted function
struct stdecs
{
struct vsmdesc stordesc;
char* tcb;
struct blkdesc *ablkdescx;
struct blkdesc *fblkdescx;
struct stdecs* nextdecs;
};
struct tcbholder
{
char* tcb;
char programname[8];
struct stdecs *storageptr;
CList<stdecs, stdecs> stptr;
};

CList features a deleted copy contructor.
Microsoft folks think it is not useful to pass collections by value.
You could use std::list instead (I believe Microsoft folks themselves recommend std::list over CList).

You are welcome.

Still get error with list me thinks it has to do that I declared stdecs just as a type without actually allocating storage i.e struct stdecs storagediscriptor; when I have the template outside of a struct it compiles thanks

This works for me:
#include <iostream>
#include <list>
using namespace std;
struct Foo
{
list <int> foolist;
};
int main()
{
Foo f1;
f1.foolist.push_back(5);
f1.foolist.push_back(7);
Foo f2 = f1;
for (auto i: f2.foolist)
cout << i << " ";
cout << "\n";
}

Get clean build seems to do more than clist thanks

I cannot create MyListBox derived from CFormView. The docs say I can put the Create call in the MyListBox ctor.
I get these errors:
// dialog template must exist and be invisible with WS_CHILD set
// invalid dialog template name
I don't want to create a resource dialog template, however, like an IDD_... because my listbox is just a PLACE_HOLDER control in a resource control.
How do I get the object created without a dialog resource IDD?

Hi,
I am following an example from a book, and I have an WaitForSingleObject that works just first time and I don't know
how to resolve that.
The main things are happening in the ChildThreadProc. At the first execution of the ChildThreadProc the procedure steps through all lines of code, but when is launched again, the execution stops at WaitForSingleObject, as if hAutoEvent isn't signaled or I don't know what is happening, and please help me to figure this out.
So,
In the WindProc main procedure when the window is created, is created the Event also:
case WM_CREATE: hAutoEvent = CreateEvent ( NULL, FALSE, TRUE, "EXAMPLE-AUTOEVENT" );
return DefWindowProc(hWnd, message, wParam, lParam);
The example of WaitForSingleObject is presented in the following procedure:
DWORD WINAPI ChildThreadProc ( HWND hWnd )
{
char szBuffer[256]; HANDLE hAutoEvent = OpenEvent( SYNCHRONIZE, FALSE, "EXAMPLE-AUTOEVENT");
wsprintf(szBuffer, "Thread %x waiting for Event %x", GetCurrentThreadId(), hAutoEvent );
SendMessage(hWnd, WM_USER, 0, (LPARAM)szBuffer);
WaitForSingleObject(hAutoEvent, INFINITE );
wsprintf(szBuffer, " Thread %x got event", GetCurrentThreadId() );
SendMessage(hWnd, WM_USER, 0, (LPARAM)szBuffer );
Sleep(2000);
wsprintf(szBuffer, "Thread %x is dome with event", GetCurrentThreadId() );
SendMessage(hWnd, WM_USER, 0, (LPARAM)szBuffer);
SetEvent(hAutoEvent);
CloseHandle( hAutoEvent);
ExitThread( TRUE );
The ChildThreadProc is started here:
case IDM_TEST:
{
DWORD id=0;
CreateThread( NULL, 0, (LPTHREAD_START_ROUTINE)ChildThreadProc, hWnd, 0, &id );
}
break;
and here is where text out is handled:
case WM_USER:
{
TCHAR szBuffer[101];
static int row = 0;
static int msg_num = 1;
HDC hDC = GetDC(hWnd);
FillMemory(szBuffer, 100, 32 );
TextOut( hDC, 0, row, szBuffer, 100 );
wsprintf(szBuffer, "%3d: %s", msg_num++, (LPSTR)lParam );
TextOut(hDC, 0, row, szBuffer, lstrlen(szBuffer) );
row = (row > 200 ) ? 0 : row += 20;
ReleaseDC(hWnd,hDC);
}
break;
Please help me to find what I am not doing right.
Thank you,

It's not signaled on the second pass. You are using an Auto-Reset event object. So when your ChildThreadProc thread exits the event goes back into a nonsignaled state. The operating system is managing this for you.

You could change to a manual signal and set/reset it yourself.

Thank you, I had made the event with manual reset and I had understood what it was to be understanded.
In additon, the main significant thing that I had catched it, it was that when the thread was exiting, even if I was signaled the event before exiting from thread:
SetEvent(hAutoEvent);
, the system automaticaly was unsigning the event.
Very tricky for me, I woldn't figured out by myself neither in 100 year, so,
Thank you very much,

You are doing an amazing job. I would be completely lost if I were forced to read Romanian documentation. I checked and unfortunately the MSDN isn't available in your native tongue. Event Objects (Romanian)[^]

Thank you,

Hi
is there a way to have one DrawItem Function if you have both a derived CStatic and CComboBox a function pointer to the drawitem function.
The Function itself takes into consideration both a static and combbox.
Not sure because the complier looks to see if you decalred a Drawitem for either a static or combobox
|
|
|
|
|
There is quite a difference between the two classes so it would not be easy. You could provide a DrawItem method for each which then calls out to a helper function to do the actual work.
|
|
|
|
|
That’s is not a bad idea Richard this may not be conventional but I think I’ll make the code part of DLL I have and pass the drawitemstruct
|
|
|
|
|
I have done vaguely similar things in the past, although not with these specific controls. And it should work the same whether it is part of the application or the DLL. The only requirement should be (I hope) that the code can distinguish if necessary between the two controls.
|
|
|
|
|
The ctltype will help yo distinguish thanks
|
|
|
|
|
I have a Clist however the type is defined as a structure
My question is I would like to match up against a member in the structure is this possible ? there maybe more that one occurence
Thanks
