I know that, ok, my code that doesn't work:

 PROCESSENTRY32* info;<br />
       HANDLE proc2;<br />
<br />
Process32First(proc2,info);<br />
	for(int i=0;i<35;i++){<br />
	Process32Next(proc2,info);<br />
	MessageBox(info->szExeFile,"OK");<br />
	if(strstr("NOTEPAD",info->szExeFile)){MessageBox("MATCH","OK");break;}<br />
	}<br />
	proc2=OpenProcess(/*PROCESS_ALL_ACCESS*/SYNCHRONIZE|PROCESS_TERMINATE,TRUE,1241980);<br />
    <br />
	m_name.Format("%d",info->th32ProcessID);<br />
	SetDlgItemText(IDC_NAME,m_name.GetBuffer(0));<br />
<br />
<br />
	if(WaitForSingleObject(proc2,5000)!=WAIT_OBJECT_0){<br />
	result=TerminateProcess(proc2,0);<br />
	MessageBox("Terminated","OK");<br />
	}else{<br />
		result=TRUE;<br />
		cw=FindWindow(info->szExeFile,NULL);<br />
		cw->PostMessage(WM_CLOSE);<br />
		MessageBox("TRUE","VIGA");<br />
	}<br />
//	if(!TerminateProcess(proc2,1)){<br />
//	}<br />
	<br />
	CloseHandle(proc2);

Well, it's only for testing... Such a mess for testing Roll eyes | :rolleyes:

Well, this should work, but how to use m_mylist.GetItemText(int nItem,intnSubItem,LPTSTR lpszText,innLen) with my code? Confused | :confused:

This will loop forever if Notepad is not running!

In order to use CListCtrl::GetItemText(), you must first have added items to the list control. I do not see any calls to CListCtrl::InsertItem() in your code.

I'm not copying all my code but the InsertItem() functions are here:

	proc=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);<br />
<br />
	info=new PROCESSENTRY32;<br />
	info->dwSize=sizeof(PROCESSENTRY32);<br />
	int id=0;<br />
<br />
	Process32First(proc,info);<br />
	m_list1.InsertItem(0,(LPCTSTR)info->szExeFile);<br />
<br />
	while(Process32Next(proc,info)!=FALSE){<br />
		id++;<br />
		m_list1.InsertItem(id,(LPCTSTR)info->szExeFile);<br />
	}<br />
<br />
	CloseHandle(proc);

This here was too only a segment of the code... OMG | :OMG:

David Crow1-Oct-03 4:33

Assuming your list control had another column:

int x = m_list1.InsertItem(0,(LPCTSTR)info->szExeFile);
sprintf(szProcId, "%lu", info->th32ProcessID);
m_list1.SetItemText(x, 1, szProcId);

Otherwise, you'll need to use:

int x = m_list1.InsertItem(0,(LPCTSTR)info->szExeFile);
LPDWORD lpProcId = new DWORD;
*lpProcId = info->th32ProcessID;
m_list1.SetItemData(x, lpProcId);

How to restore minimized window?

I did so:

and it was not succeded -Why?

<br />
					pDlg->ShowWindow(SW_SHOW);<br />
					pDlg->SetFocus();<br />
<br />
				WINDOWPLACEMENT wndpl;<br />
				pDlg->GetWindowPlacement(&wndpl);<br />
				//memset(&wndpl,0,sizeof(wndpl));<br />
				<br />
				wndpl.length = sizeof(wndpl);<br />
				wndpl.flags = WPF_SETMINPOSITION ;<br />
				wndpl.showCmd= SW_SHOWMAXIMIZED | SW_SHOW;<br />
<br />

CSocket - CSocketFile - CArchive Problem

Brian Cox30-Sep-03 3:04

Hello,

I am having some difficulty using the CArchive socket class in a storing (output) situation. My problem is with the m_pArOut pointer in the following code. It seems that for some unknown reason I am unable to write using the CArchive. Here is a code snippet:

----------------------------------------------------------------
<>

sockClient.Create();<br />
sockClient.Connect("192.168.1.112",3030);<br />
<br />
file = new CSocketFile(&sockClient);<br />
<br />
m_pArIn = new CArchive(file,CArchive::load);<br />
m_pArOut = new CArchive(file,CArchive::store);<br />
<br />
*m_pArOut<<"This is a test";

----------------------------------------------------------------
<>

CSocket	sockClient;<br />
CSocketFile* file;<br />
<br />
CArchive* m_pArOut;<br />
CArchive* m_pArIn;

----------------------------------------------------------------

When this code is executed I do not receive the message “This is a test” on my server. However, if I change the code to use a local version of the CArchive object like the following it works:

----------------------------------------------------------------

CArchive	arOut(file,CArchive::store);<br />
m_pArOut = &arOut;

----------------------------------------------------------------

The user of the pointer m_pArIn works in every case. I don’t understand why it would work when locally instantiated. I also don’t understand why the same problem doesn’t exist for the input archive.

Thank you for your help

Confused | :confused:

I'm a bit of a beginner, but if I were you, I'd try flushing the output after you send "This is a test";

m_pArOut->Flush();

Hope this works for you!

Thanks for the reply Doug. I too am new to VC++. I usually program in straight C in UNIX or VxWorks OS.

I tried flushing before, but no dice. It is the strangest thing, since it works if the object is instantiated locally.

Thanks again

hi,

up to now spy++ worked great, but from one moment to the other it won't display dispatched messages... and that happens with every program i want to spy!

Can somebody imagine what's wrong ?

MFC ShellExecuteEx structure

I'm still new to c++ so please bare with me.

I'm using the ShellExecuteEx in MFC to open a Acrobat .pdf document.
When Acrobat is closed after the document has opened or the process is closed I want to remove the file from the Directory.

my code looks like this.

<br />
//***************************************************************************<br />
char pathBuffer[MAX_PATH];<br />
char szCurrDir[MAX_PATH];<br />
<br />
GetCurrentDirectory(MAX_PATH,szCurrDir);<br />
GetTempFileName (szCurrDir, "", 0, pathBuffer);<br />
CString stmpfile = pathBuffer;<br />
<br />
SHELLEXECUTEINFO si;<br />
	memset(&si, 0, sizeof(si));<br />
	si.cbSize = sizeof(si);<br />
	si.hwnd = this->m_hWnd;<br />
	si.lpVerb = "open";<br />
	si.lpFile = pathBuffer;<br />
	si.nShow = SW_NORMAL;<br />
	si.hInstApp = NULL;	<br />
	si.fMask = SEE_MASK_NOCLOSEPROCESS;<br />
	int res = ShellExecuteEx(&si);<br />
	if (res==1)<br />
		WaitForSingleObject(si.hProcess,INFINITE);<br />
   <br />
<br />
        CloseHandle(si.hProcess);<br />
<br />
<br />
	//Remove the temp File from Directory<br />
	remove(stmpfile);<br />
//***************************************************************************<br />

When there is no instance of Acrobat running it works fine. But as soon as Acrobat is already running or an instance of the Acrobat exe still in the process tray it doesn’t seem to open the .pdf document.

I cannot use the ShellExecute structure for the simple reason that I need to know when Acrobat is closed so that I can remove that file from the directory.

The ShellExecute will open the Acrobat document regardless of whether there an instance is of Acrobat running.

//ShellExecute(this->m_hWnd,"open",pathBuffer, NULL, NULL, SW_SHOWNORMAL);

Any help would really be appreciated.
