In addition to what Mike Nordell said, if you know the title text of the main window you might FindWindow() it. Now PostMessage a WM_CLOSE to this HWND. You can use GetWindowThreadProcessId() on the HWND returned to get the thread id and process id of the thread that created the window.

Well, if you know the process ID, you can use OpenProcess to get a handle. In NT/2000/XP, you can view the PID in the task manager (you might have to tell it to show the PID in the view menu).

what is the difference of Debug Multithreaded & Debug Multithreaded DLL?
how if I use the Debug Multithreaded DLL when I am making a exe?
thanks
|

Debug multithreaded is a static LIB - the CRT code is linked into your EXE. The Debug multithreaded DLL option makes your EXE link with the CRT DLL. This makes your EXE smaller, but you then have to ensure the DLL is on the computers your program will run on.

When you implement any type of project, you must know which library you're linking your project with. You select a library using the Project Settings dialog box, shown below. On the C/C++ tab, in the Code Generation category, select one of the six options from the Use Run-Time Library combo box.
The first thing you're probably wondering is, "Why do I need one library for single-threaded applications and another library for multithreaded applications?" The reason is that the standard C run-time library was invented around 1970, long before threads were available on any operating system. The inventors of the library didn't consider the problems of using the C run-time library with multithreaded applications.
Consider the standard C run-time global variable errno. Some functions set this variable when an error occurs. Let's say you have the following code fragment:
BOOL fFailure = (system("NOTEPAD.EXE README.TXT") == -1);
if (fFailure) {
switch (errno) {
case E2BIG:
break;
case ENOENT:
break;
case ENOEXEC:
break;
case ENOMEM:
break;
}
}
Now let's say that the thread executing the code above is interrupted after the call to the system function and before the if statement. And imagine that the thread is being interrupted to allow a second thread in the same process to execute and that this new thread will execute another C run-time function that sets the global variable errno. When the CPU is later assigned back to the first thread, the value of errno no longer reflects the proper error code for the call to system in the code above. To solve this problem, each thread requires its own errno variable. In addition, there must be some mechanism that allows a thread to reference its own errno variable but not touch another thread's errno variable.
This is only one example of how the standard C/C++ run-time library was not originally designed for multithreaded applications. The C/C++ run-time library variables and functions that have problems in multithreaded environments include errno, _doserrno, strtok, _wcstok, strerror, _strerror, tmpnam, tmpfile, asctime, _wasctime, gmtime, _ecvt, and _fcvt—to name just a few.
For multithreaded C and C++ programs to work properly, a data structure must be created and associated with each thread that uses C/C++ run-time library functions. Then, when you make C/C++ run-time library calls, those functions must know to look in the calling thread's data block so that no other thread is adversely affected.

I need to hilight certain words on HTML Page (from VC through COM). How can I do it? Desirable it seens like in Find Dilog in IE. Or how can I implement behavior of find Dialog (hilight a matching words step by step)?

Hi! That's my code to start IE and connect to its events:
void CMFCIEEvtSpyDlg::OnStartIE()
{
if (m_pIE == NULL)
{
HRESULT hr = CoCreateInstance(CLSID_InternetExplorer, NULL, CLSCTX_LOCAL_SERVER,
IID_IWebBrowser2, (void**)&m_pIE);
if (SUCCEEDED(hr))
{
BOOL bAdvised = AfxConnectionAdvise(m_pIE, DIID_DWebBrowserEvents2,
m_pIE4Events->GetInterface(&IID_IUnknown),
TRUE, &m_dwCookie);
TRACE("Advise for DWebBrowserEvents2 %s\n", bAdvised ? "succeeded" : "failed");
m_btnStartIE.EnableWindow(FALSE);
m_pIE->put_Visible(VARIANT_TRUE);
CString strURL;
strURL.LoadString(IDS_HOME_PAGE);
COleVariant vtEmpty;
m_pIE->Navigate(strURL.AllocSysString(), &vtEmpty, &vtEmpty, &vtEmpty, &vtEmpty);
}
}
}
In release bild all works correctly, but in Debug function call m_pIE4Events->GetInterface(&IID_IUnknown) failed (returns NULL). I can't understand, why. Here's a source and compilied release (65 K) [new browser window].
Please, help me!! Thanks!

When running the next program, I get the next error:
"Unspecified error Microsoft cursor Engine Key column information is insufficient or incorrect. Too many rows were affected by update".
A segment of the program is:
_RecordsetPtr pRs;
_ConnectionPtr m_pConn;
CString sErr;
HRESULT hr=0;
CoInitialize(NULL);
hr=m_pConn.CreateInstance(__uuidof(Connection));
m_pConn->Open (_bstr_t("DSN=egadb"), _bstr_t("scott"), _bstr_t("tiger"),
adConnectUnspecified);
_CommandPtr pCommand;
pCommand.CreateInstance (__uuidof (Command));
pCommand->ActiveConnection = m_pConn; // Formerly opened connection pointer
pCommand->CommandText = "select campo16, campo17, campo18, monto from carga";
variant_t vNull;
vNull.vt = VT_ERROR;
vNull.scode = DISP_E_PARAMNOTFOUND;
pRs.CreateInstance (__uuidof (Recordset));
pRs->CursorLocation = adUseClient;
MessageBox("Ahí voy con el recordset");
pRs->Open( (IDispatch *) pCommand, vtMissing, adOpenForwardOnly,
adLockOptimistic, adCmdUnknown);
CString pfldEName, pfldJob, stmp;
BeginWaitCursor();
try {
for (int i=1; i<2; i++) {
stmp.Format("%s", (char *) (_bstr_t)pRs->GetCollect("campo17"));
CString sValAux="";
pRs->PutCollect("campo18", _variant_t(atof(stmp)));
pRs->Update(vNull, vNull);
pRs->MoveNext();
}
pRs->Close();
}
catch (_com_error &e) {
sErr.Format("%08lx %s %s %s", e.Error(), e.ErrorMessage(),
(LPCTSTR) bstrSource, (LPCTSTR) bstrDescription);
MessageBox(sErr);
}
EndWaitCursor();
}
The table to update has more than 600,000 records. May be is it necessary to establish checkpoints?
Thank you in advance for you help!!

if i have an ATL Dialog inside a dll library, how can i call it from an MFC program, it is a regular MFC DLL?
|
|
|
|
|
|
i just add a new atl object and in miscelaneus choose dialog
|
|
|
|

The ATL object wizard will create a dialogs. However WTL makes life much easier (especially if you are used to the easy MFC life, like I was)

I tend to wrap my Dialog in a Simple Object wrapper with a Show Method and then in my MFC App, I create an instance of my object and call the Show method.

Hi,
You know when you load a non-normal resource it will open it in some sort of Binary or Hex viewer? Could someone explane very precisly what all of it means? There are three columns, one on the left that appears to mark lines, one in the middle that appears to have the data, and some strange column on the right. I'm most interested in the column on the right.
Thanks,
~ Selevercin

I believe the right most column tries to show the data as text.

The three columns are in order:
1 Offset - the hexadecimal offset of the beginning of that line (within that resource)
2 Data - hexadecimal representation of that "line" of data. Often 16 bytes is represented/line.
3 ASCII representation of that data.
|
|
|
|

Is there a way to copy the "data"? Every time I try, I get the ASCII part of it?
Thanks,
~ Selevercin

What you get on the clipboard is the raw data. No, you can't copy the ASCII representation of the hexadecimal representation of the data. You can however paste it into a "binary file" (MSVC term) window, save that, and then use some "hexdump" command-line utility to get it.
No, I won't write a hexdump utility for you.

Any program that does this?
This is required when i want to know the resource symbol/ID of the control on the dialog quickly. I hate clicking on properties and finding out what the symbol is.
This is used for ETSLayout, when i'm adding the controls to the panes.
Thanxs in advance!

Ah found it

Just need to enable the annotate item with ID.
Any other programs?

I need an unresizable dialog. I was thinking of getting the size at the beginning of the program then if the user tried to resize it I would just reset it back to the original size. However, I've seen programs that don't even display the resize arrows. I tried playing with the dialog settings but it doesn't seem to work. Any ideas?

dialogs are unresizable by default, and you can disable the max/min/restore buttons in the resource editor.

hmmm, well my dialog is resizable. Do you know what the default settings are? When it is a popup or overlapped dialog it crashes when the program starts. When it is a child it works, but I can't add/remove the min and max buttons. It is a dialog based app. Is that the problem?

go in the resource editor, open your dialog. click the Styles tab. choose "Dialog Frame" as the border type. click Title Bar and System Menu. (and min/max boxes, if you want). those are the defaults.
