2 threads
first threads,DllRegisterServer the 1.ocx(MFC),then FreeLibrary it; and 2.ocx,3.ocx.....
secend threads,DllRegisterServer the A.ocx(MFC),then FreeLibrary it; and B.ocx,C.ocx.....
A thread deadlock in GetModuleFileName when another thread is in FreeLibrary.The GetModuleFileName is called by
DllRegisterServer.-_-!
why???? MFC's Bug?GetModuleFileName is a API!!!!!!

The DLLMain is only supposed to be called for a single thread within a process at a time.
If you are loading and freeing libraries from various threads, none of those libraries should have ANY dependencies upon each other, or you will see strange results.
Also, no threads that are 'created' within the DllMain context will actualy start running until the DllMain that created the thread returns.
This could be part of your problems.

1、The libraries have not any dependencies upon each other.
2、Threads aren‘t created in the DllMain.
The thread really is deadlock in "GetModuleFileName" and FreeLibrary.
The GetModuleFileName is called in DllRegisterServer(MFC).
If DllRegisterServer isn't called in thread, the thread can't deadlock.You can test it.

I'm trying to programatically create an email using the current mail client, with an attachment. I don't want to send the mail from my program, because I'd like the user to customize his mail after my program starts the mail and adds the attachment for him.
Isn't there a simple way to simply duplicate the 'Send To Mail Recipient' functionality in Explorer?
Maybe there is a way I can simulate someone performing this action from my program, to get the desired results?
I've seen some samples on here, but they all work independent of the mail client, which is the opposite of what I need. Thanks!

try to use WriteProcessmemory() func and make the explorer do all the dirty work :DD

hello all,
i have the following code to print the excel file
<br />
VARIANT tv;<br />
VARIANT tv1;<br />
VARIANT tv2;<br />
VARIANT tv3;<br />
VARIANT tv4;<br />
VARIANT tv5;<br />
VARIANT tv6;<br />
VARIANT tv7;<br />
<br />
tv3.vt = VT_BOOL;<br />
tv3.iVal = false;
<br />
tv4.vt = VT_BSTR;<br />
tv4.bstrVal = printerName.AllocSysString();
<br />
tv5.vt = VT_BOOL; <br />
tv5.iVal = false;
<br />
tv6.vt = VT_BOOL;<br />
tv6.iVal = true;
<br />
tv7.vt = VT_BSTR;
tv7.bstrVal = CString("").AllocSysString();<br />
<br />
tv.vt = VT_I4;<br />
tv.lVal = 1;
<br />
tv2.vt = VT_I2;<br />
tv2.iVal = 1; <br />
<br />
sheets.PrintOut(covOptional, covOptional, tv2, tv3, tv4, tv5, tv6, tv7 );<br />
the excel file contains charts and it is giving me error. if there is no charts i don't get error at all and it is printing.
why is it chart giving me error?
|
|
|
|
|
tv3.vt = VT_BOOL;
tv3.iVal = false; VT_BOOL is not the same as a C++ bool nor a C++ BOOL. Use this:
tv3.vt = VT_BOOL;
tv3.boolVal = VARIANT_FALSE; The legal values for a boolean VARIANT are VARIANT_TRUE and VARIANT_FALSE.

No.. it doesn't help.
As I told you.. printout method doesn't give me any problem when the excel file doesn't contain chart.
the file get print out automatically. but the file with charts.. i get error.
is it because of covOptional?
<br />
COleVariant covTrue((short)TRUE),covFalse((short)FALSE),covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);<br />
<br />
sheets.PrintOut(covOptional, covOptional, tv2, tv3, tv4, tv5, tv6, tv7 );
No it can't be either.. because I had tried setting up from = 1 to To = lastPage. and got the same result which is the file without chart sheet in it print out automatically. but not the file with the chart sheet in.
<br />
tv.vt = VT_I4;<br />
tv.lVal = 1;
<br />
tv1.vt = VT_I4;<br />
tv1.lVal = lastPage;
<br />
tv2.vt = VT_I2;<br />
tv2.iVal = 1;
<br />
sheets.PrintOut(tv, tv1, tv2, tv3, tv4, tv5, tv6, tv7 );<br />

I found out why there is an error
It is nothing to do with chart..
Printout method get error because there are some hidden sheet
to solve the problem, I only have to set the sheet to visible.
sheet.SetVisible(1);

I want to prevent computer from being shut,my codes as below:
BOOL CMyTestDlg::OnQueryEndSession()
{
return FALSE;
}
BOOL CMyTestDlg::OnInitDialog()
{
if(SetProcessShutdownParameters(0x4ff,SHUTDOWN_NORETRY)==0)
{
MessageBox("SetProcessShutdownParameters Failure");
return ;
}
}
void CMyTestDlg::OnButtonOk()
{
ShutDownCodes();
}
MSDN say program can prevent computer from being shut by enhance the program level by SetProcessShutdownParameters,but After I clicked the OkButton the Computer is shut down,what should I do?
|
|
|
|
|
msdn says this about SetProcessShutdownParameters()...
"This function sets a shutdown order for a process relative to the other processes in the system."
Its does not say that it allows a process to terminate the shut down process.
I think this fucntion AbortSystemShutdown() is what you are looking for but Im not sure

WM_QUERYENDSESSION
The WM_QUERYENDSESSION message is sent when the user chooses to end the session or when an application calls the ExitWindows function. If any application returns zero, the session is not ended. ////The system stops sending WM_QUERYENDSESSION messages as soon as one application returns zero.
/////
After processing this message, the system sends the WM_ENDSESSION message with the wParam parameter set to the results of the WM_QUERYENDSESSION message.
A window receives this message through its WindowProc function.
WM_QUERYENDSESSION is sent to program from the high Shutdown priority to low

Hi everyone, i am getting angry while trying to insert richedit control, to my small dialogbox application.
Well, everything works fine to the moment i put the richedit control on my dialogbox, then
application starts and exits in some of 1ms.
My program is basically a dialogbox application, i wanted to implement a nicee richedit control but when i only put her inside the dialogbox, the app does not work!
Any ideas?
ps1. hwnd= DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), 0, MainDlgProc);
that's how i init my main program dialog box
ps2. all other controls beside richedit - work fine, i'm having a big problem.

If you are using a rich edit control in a dialog box (regardless whether your application is SDI, MDI, or dialog-based), you must call AfxInitRichEdit once before the dialog box is displayed. A typical place to call this function is in your program’s InitInstance member function. You do not need to call it for each time you display the dialog box, only the first time.
e.g.
BOOL CMyApp::InitInstance()
{
AfxEnableControlContainer();
AfxInitRichEdit();
………………………….
}

I need to write a program in visual C++ 6.0 that will read and HTML file and modify contents programmatically. Especially I need to cause the pushbuttons within the HTML file to execute. Can anyone help me with this.

Reading and modifying HTML is easy if it's XHTML, just read it into an XML document. How do you mean you want the buttons to execute ? You actually want not just to read them, but to run them in a browser programatically ?

Hi,
Yes, guess I wasn't too clear. I have to program a "wrapper" around some existing HTML code. Within the HTML code I want to choose certain selections in the HTML and cause them to execute but keep the HTML code from being visible, so I guess that would be as you say to run them in the browser programatically. I have been reading up on the IDispatch methods from Microsofts web site, but can't seem to make it work.
Thanks for your help

My aim is to control the backColor of the CStatic that I use in my app. So I derived a class from CStatic . Now The text that gets displayed needs to be according to a Custom font. I am handling the
BOOL CHeadingStatic::OnChildNotify(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pLResult) <br />
{<br />
if (message != WM_CTLCOLORSTATIC)<br />
{<br />
return CStatic::OnChildNotify(message,wParam,lParam,pLResult);<br />
}<br />
HDC hdcChild = (HDC)wParam; <br />
if(colored)<br />
SetBkColor(hdcChild,RGB(0,120,120));<br />
*pLResult = (LRESULT)(m_brush.GetSafeHandle());<br />
return TRUE;<br />
}
Now I added another public
<br />
void CHeadingStatic::ChangeFont()<br />
{<br />
SetFont(&headingFont);<br />
<br />
} method in this class to change the Font .
So externally I first creating this object and then
doing an
<br />
object.create(......)<br />
object.ChangeFont()
I notice a lot of flickering and it takes a while to come up . Is there a way i can do this during creation ?
Engineering is the effort !

I have:
(nh-nl + 1) 1247923961
and calloc fails:
v=(double *)calloc((nh-nl+1),sizeof(double));
v is zero.
How do I fix this? Why is this happening?

I think you are trying to allocate over 2GB of space.
