Are you Attaching another CWnd-based object to one of your windows controls?
The reason it works in release mode is likely not because the error/problem goes away, it is because there is no diagnostic code to report on it. There are very few errors that are a true result of the Debug mode of the Compiler/Linker.
The only thing that jumps out at me is that you are allocating into pMySheet, which is a local variable. That means that you are either really leaking it, or deleting it later in the same function, when it looks like the CMySheet object is supposed to have a longer lifetime. Either way, it looks like that pointer is being mismanaged.
Peace!

Hi,
I am trying to insert items in VB List View control from VC++ dll using SendMessage API. its in the same process and even the handle of list view is proper. I am using this code.. but it does not insert the item ...
TCHAR msgString[512];
TCHAR tempString[128];
wsprintf(tempString, _TEXT(" MsgId: %03d "), message->buffer[8] );
_tcscpy(msgString, tempString );
_tcscat(msgString, _T("sadsadsdsad "));
LVITEMW LvItem;
LvItem.mask=LVIF_TEXT; // Text Style
LvItem.cchTextMax = 256; // Max size of test
LvItem.iItem=0; // choose item
LvItem.iSubItem=0; // Put in first coluom
LvItem.pszText=msgString; // Text to display (can be from a char variable) (Items)
SendMessage(hwndMsgRqst,LVM_INSERTITEM,0,(LPARAM)&LvItem); // Send info to the Listview
I am able to get the item count using LVM_GETITEMCOUNT
Any help is really appreciated

I don’t know how much this will help or not but here is how I accomplished a similar task with a list box. This is a snippet of the real code, just for example sake.
<br />
CPP<br />
#define AddListText(hwnd, txt) \<br />
( int )SendMessage( ( hwnd ), LB_ADDSTRING, 0, ( LPARAM ) (LPCTSTR) txt)<br />
<br />
<br />
void AddListString(long lhwnd, LPCTSTR sAdd)<br />
{<br />
HWND hwnd = (HWND) lhwnd;<br />
AddListText (hwnd, sAdd);<br />
}<br />
<br />
VB<br />
Private Declare Sub AddListString Lib "SCC_DLL.dll" (ByVal lhwnd As Long, ByVal sAdd As String)<br />
<br />
Private Sub cmdAddString_Click()<br />
Dim sText As String<br />
sText = "Text"<br />
AddListString List1.hWnd, sText<br />
End Sub<br />
In a few hours I will be in front of my workstation and be able to try something similar with a list view if yea like.

Hi thanks for the code...
It works fine if we are sending string or string pointer.
But if we pass structure( in case of list view), it does not work out. could u pls try with listview

No problem, if you can send me the snippet of code (it will make it easier) that would be great.
I'm no C++ expert / guru. But I do enjoy a challenge.
[edit]
I can’t guarantee I will get to it this weekend (the Girlfriend has barred me from working on the weekends, something about being bored watching me sit in front of the computer for > 12 hrs)

 enjoy the weekend
please find the snippet..
VC++ code:
**************************************************
DLL_EXPORT_VB void __stdcall RegisterLogWindow(HWND hwndMsgLog, HWND hwndMsgRqst )
{
TCHAR msgString[512];
memset(msgString, 0, sizeof (msgString));
SYSTEMTIME st;
GetLocalTime(&st);
wsprintf(tempString, _TEXT(" Dt: %02d:%02d:%04d - %02d:%02d:%02d:%03d "), st.wDay, st.wMonth, st.wYear, st.wHour, st.wMinute, st.wSecond, st.wMilliseconds );
_tcscat(msgString, tempString );
int iItem=SendMessage(hwndMsgRqst,LVM_GETITEMCOUNT,0,0);
//LVITEMW LvItem;
LVITEMW LvItem1;
LvItem1.mask=LVIF_TEXT; // Text Style
LvItem1.cchTextMax = 256; // Max size of test
LvItem1.iItem=iItem ; // choose item
LvItem1.iSubItem=0; // Put in first coluom
LvItem1.pszText= msgString; // Text to display (can be from a char variable) (Items)
int hr = SendMessage(hwndMsgRqst,LVM_INSERTITEM,0,(LPARAM)&LvItem1); // Send info to the Listview
int err = GetLastError() ;
}
**** hr and rr returns 0.... itemcount got is correct
************************************

Sorry Mohamed, I was unable to get it fully working as well. I will keep working on it; it’s an interesting idea.
I kept getting access-denied errors from the list view.

What are the available error codes after the call fails? Both the return code of the call to SendMessage(...) and the value returned by GetLastError() (note that you have to call GetLastError() right after the call to SendMessage(...)).
BTW: you are taking "the long way around" to build the contents of msgString...
Peace!

Both SendMessage and GetLastError returns 0..

If the call returns successful return/error codes, and the Item Count increases after the call, my guess is that you have a redraw problem.
Try forcing a redraw of the application/control and see if your item shows up. Also, make sure that column zero has a real width. With a multi-column ListView control, if Column 0 has a width of zero, newly added items with no subitem text will be effectively invisible.

Hi all,
When any document is opened in ms word then it also creates .tmp file in same folder/temp folder. I want to stop such .tmp file creation.
How can i do that ? Can it be done by some option in MSWord settings? can it be done by writting addin DLL for that? or thru can it be done by writing COM,VC++ application ?
Please Let me know if it is possible? how? by which method?
Any suggestion are welcome.
Thank in advance.

they're automatic recovery files.
go in the tool\options\file location
and either turn off automatic recovery or point it
to a different folder (it's a good feature, but
you may not want it in with your .doc files
because it crowds your directory

Yes u are right.
But Even if i uncheck those option, word still creates .tmp file.
Does anybody has point to this?
How to prevent word from creating ,tmp file, by any means (COM Addin, programmatically etc...)
Thanks

I'm looking for multi-user server source code (tutorial) (C/C++, sockets, no MFC).
Oh, I already know how to do multi connections the windows way (messages sent to my window when data is received), but that's not what I want.
I know there are some here at codeproject but they all use MFC (yuck) and seem alot more complicated then what I've found so far.
I found the original at www.planet-source-code.com (I've re-done and simplified it for this post):
SOCKET ServerSocket;
SOCKADDR_IN server_address;
FD_SET masterSet;
HANDLE ThreadHandle;
DWORD ThreadID;
int RetVal = 0;
DWORD WINAPI acceptingThreadProcedure(LPVOID ServerSocket)
{
SOCKET* Socket = (SOCKET*)ServerSocket;
SOCKET ClientSocket;
while(1)
{
ClientSocket = accept(*Socket,0,0);
FD_SET(ClientSocket,&masterSet);
printf("Client on %d connected\n",ClientSocket);
}
return TRUE;
}
int InitServer()
{
WSADATA wsaData;
WSAStartup(MAKEWORD(1,0),&wsaData);
ServerSocket = socket(PF_INET,SOCK_STREAM,0);
server_address.sin_family = AF_INET;
server_address.sin_port = 4200;
server_address.sin_addr.s_addr = INADDR_ANY;
bind(ServerSocket,(SOCKADDR*)&server_address,sizeof(SOCKADDR_IN));
listen(ServerSocket,5);
ThreadHandle = CreateThread(NULL,0,acceptingThreadProcedure,&ServerSocket,0,&ThreadID);
Sleep(100);
FD_ZERO(&masterSet);
FD_SET pollingSet;
timeval waitTime;
waitTime.tv_sec = 0;
waitTime.tv_usec = 0;
SOCKET clientSocket;
unsigned long BufferSize;
while(1)
{
pollingSet = masterSet;
if(pollingSet.fd_count == 0)
continue;
RetVal = select(pollingSet.fd_count,&pollingSet,NULL,NULL,&waitTime);
if(RetVal == 0)
continue;
for(unsigned int i = 0; i < pollingSet.fd_count; i++)
{
clientSocket = pollingSet.fd_array[i];
recv(clientSocket,(LPSTR)&BufferSize,sizeof(BufferSize),0);
BufferSize = ntohl(BufferSize);
LPSTR Buffer = new char[BufferSize];
recv(clientSocket,(LPSTR)Buffer,BufferSize,0);
Buffer[BufferSize] = '\0';
printf("Client %d: %s\n",clientSocket,Buffer);
delete[] Buffer;
}
}
}
I've been looking for tutorials that teach it with FD_SET and select but havn't found anything yet.
Does anyone know of a good tutorial?
P.S. The reason I'm looking for something more than what I've found is that the current code (above) doesn't have a way to send data back, and I'm not sure how to add that. Also the code just doesn't seem right (tho I don't know what multi-user code looks like), and it uses 100% system resources.
Alright, thank you much.

if I want to export a global operator+ overload, like
String operator+( const String& lhs, const int& rhs );
If I define this in a header, like
__declspec( dllexport ) String operator+( const String& lhs, const int& rhs );
and then implement this in a .cpp like
__declspec( dllexport ) String operator+( const String& lhs, const int& rhs )
{
return ....
}
it compiles and builds the DLL fine. When I link to the dll from an exe, however, I get linker errors claiming "String operator+(..." isn't defined.
What am I doing wrong? Is it not possible to have the implementation in a .cpp file?
Thanks !
