I have a problem in a multi-dll project. Everything works except for an access violation in the CCmdTarget Destructor. Its a CEdit Control I'm actually not using. Now heres where the fun starts, remove the CEdit, and the Spin control in the same dialog now asserts setting the range, claiming it is not a window. Want some more fun? Remove the Spin Control from the dialog class, and now operator new breaks during heap alloc doing a heap check, which then fails no matter how many times you continue (big surprise (end sarcasm)). I had thought maybe it was my use of the MS STL not being DLL safe, so I grabbed stlport, and have the exact same results. I'm not doing anything odd in this code, which is why I did not post it. Instead, I suspect I have done something really dumb somewhere else and have just overlooked it, and am hoping someone here may have done the same dumb thing, or know someone who has, and knows what I have done wrong.
Other steps I have taken: Resource ID confilcts resolved. Making the property pages not be global variables, but instead be on the heap.
The behavior has not changed from the original problem.
Additional Info: m_xDispatch.m_vtbl=2696277389 m_dwRef=1051772663 in the CCmdTarget Destructor, it bails on the line ((COleDispatchImpl*)&m_xDispatch)->Disconnect();
Thanks in advance

I've written two seperate dialog based applications. Now I want one of them to send a message to the other, telling it it's status. I've tried postmessage, but it does no seem to pass my CString pointer. In my message event there is nothing in the lparam. I've set it up like naughter suggests but I'm wondering if I'm doing something wrong.
Some questions: In order to sendmessages between two different apps, do I need to register my message?
Can you not send a pointer between two different apps? I've done this using threads between my main app and the threads.
Thanks
Tom

Short answer: no. Each process has its own process space, memory from one is not visible in others, and addresses in one are meaningless in others. You need to use an IPC mechanism, WM_COPYDATA will probably be easiest since you're already using message to communicate.

I'm trying to pass a struct with the WM_COPYDATA. How would I receive this on the receving side of my app. Currently this is how I'm doing it right now:
ConnStatus *cConnStatus;
//CString strRecievedText = (LPCSTR) (pCopyDataStruct->lpData);
memcpy(cConnStatus, pCopyDataStruct->lpData, pCopyDataStruct->cbData);
AfxMessageBox(cConnStatus->cID);
I get an assert error, and I think it's because I'm trying to pass lpdata to a pointer to my struct.
Do you have any suggestions on how to do this?
Thanks

To send just a string, do this in the sending side:
COPYDATASTRUCT cds = {0};
CString sTheData = _T("foobar");
cds.lpData = (LPCTSTR) sTheData;
cds.cbData = (sTheData.Length()+1)*sizeof(TCHAR);In the receiving side:
BOOL CAppWindow::OnCopyData ( HWND hwndSrc, COPYDATASTRUCT* pcds )
{
CString s = (LPCTSTR) pcds->lpData;
}If you have a whole struct, you need to get all the data into one contiguous buffer so the system can copy it into shared memory for the target process to use.

i'm using VC++6;
i want to declare a global variable(i.e., to be seen in all the classes of the app)
i tried to declare it n CMyApp ( : public CWinApp) but an error message (undeclared identifier) usually appears..
regards.
keep the matter as simple as it can be !!

what errror ? and where does the error appears ?
you need to #include your app class .h file in the files you will access CMyApp

hi
ypu can declare the "extern int <variable name>" in your stdafx.h the applications global file where you have to use that variable again declare there in that header file your change will affect to the original global variable.
I think this works

I have this code:
//BEGIN ====================
IP_ADAPTER_INFO AdapterInfo[16];// Allocate information for up to 16 NICs
DWORD dwBufLen = sizeof(AdapterInfo);// Save the memory size of buffer
DWORD dwStatus = GetAdaptersInfo(// Call GetAdapterInfo
AdapterInfo,// [out] buffer to receive data
&dwBufLen); // [in] size of receive data buffer
PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo;// Contains pointer to current adapter info
//END========================
I want to convert the pAdapterInfo->Address to a std::string
Can anybody help me on this?
Thanks in advance.

Well,
It worked pretty well:
std::string MACData2String (unsigned char MACData[]){
std::string tmp;
char slask[100];
sprintf(slask,"%02X-%02X-%02X-%02X-%02X-%02X", MACData[0], MACData[1], MACData[2], MACData[3], MACData[4], MACData[5]);
tmp=slask;
return tmp;
}

Hello!
How can I open .col files with hh.exe? I already installed the latest version of HtmlHelp Workshop and tried to run the hhupd.exe, but it tells me that I got a newer version already (I'm using Windows XP SP2).
Do I have to install any update? How to make hh.exe open .col files?
Thanks in advance and best regards

Hi, i got a little problem.
In CEdit if we set Number=true we can only enter numerical characters and if we press a non-numeric char, there is an "information message"
My question,
1) is it possible to use something to accept "." s for floating numbers
2) if 1st one is not possible, is there any way to show that information message while not using Number=true format.
Thanks

If you need floating-point numbers, you'll need to use a custom (masked) edit control. There are several here at CP.

OK. in CEdit when we choose number=true, and we enter a non-numeric character there is an error message like a tooltip. that writes something like not to enter non-numeric characters. Can i call that tooltip(or whatever it is), while not using number=true format.

Yes, check out CWnd::EnableToolTips() as well as the CToolTipCtrl class.

HI all,
is it possible to pre-pend to a CString as opposed to append, ie place a new string at the start of the string instead of the end. Thanks

Yes, just switch the order of the operands. Something like:
CString name("is David");
name = "My name " + name;Make sense?
