Thank you.

//This gives me HWND to the external app HWND hWnd = ::FindWindow(NULL, "TEST"); From hWnd, how do i get the HWND for a picture control in that application? From Spy I get "Window 000406F2 "" Static" It has a control id of 000003E8 Can someone please help? Thanks a million.

I am getting it in disassembly.

I did 3 different projects and with all I did a rebuild.. thinking of the same thing?

I am sorry I am not trying to be a pain. :(( This is frustratung me... Here is what I did...Any suggetions... On a different machine i went down in versions..from 2008-2005-and finally to VStudio 6. I used the same steps in all ..I got the same exception error except in Vstudio 6..Where I got no exception error...Imported the same project into my Visual Studio 2008 and it works fine...No First-chance error. I am not sure what to do? :(( ...Well for now I can work with this imported project...but is this really a solution?...I have come to the end of the rope on this one...If I did something wrong, would VStudio 6 not complain as well? Do you think you can advice me as what to do? I don't like to give up, at the sametime I don't want to be hitting my head if it is a bug in VStudio 2008? I can't see me to be the only one trying or using the property sheet based application? Thanks, I will really appreciate some sort of feed back, I am new at this and it's frustrating me..Please advice. :)

[http://msdn.microsoft.com/en-us/library/0bw65cxb(VS.80).aspx](<a href=)[^]"> This article states to ignore the return value from the CPropertySheet Class, unless I mis-understood it. Does that mean I ignore the exception as well?

in debug before I go here no exception error: BOOL bResult = CPropertySheet::OnInitDialog(); I get the error inside this...

Thank you. I am trying to follow some intructions on how to create Property sheet based application. When I compile and run in degug mode I get: I am getting First-chance exception at 0x5d0c373e in LastTry.exe: 0xC0000005: Access violation writing location 0x00416e8c. In debug mode however when i exit I get a The program '[3124] LastTry.exe: Native' has exited with code 0 (0x0). I was able to get the original source code from the demo site. When I compiled that and ran it. There was no exception. There is one line in my stdafx.h which is not in the original source code. It is to do with : #include <afxcontrolbars.h> // MFC support for ribbons and control bars How do I resolve this issue? I have tried to comment the above line obviously gives me more compile errors. What could I have done wrong? Or is it something that was not right in my install of VStudio 2008?

Is it possible to copy settings from one project to the other. If so how to do it?

This is where i am stuck in the debgugger. Not sure whats happening?

BOOL AFXAPI AfxDeactivateActCtx(DWORD dwFlags, ULONG_PTR ulCookie)
{
BOOL rc = pfnDeactivateActCtx != 0 ? pfnDeactivateActCtx(dwFlags, ulCookie) : FALSE;
return rc;
}

Why would it exit with a 0 if I haven't changed anything else in the code? Would it not give me a memory leak or something?

Can Someone help I am not sure whats wrong. I am getting the following debug message: First-chance exception at 0x5d0c373e in Capture Data.exe: 0xC0000005: Access violation writing location 0x0043454c. However on exit I get: The program '[1284] Capture Data.exe: Native' has exited with code 0 (0x0). Here is the code I have used:

BOOL CCaptureDataApp::InitInstance()
{
InitCommonControls();
CWinApp::InitInstance();
CCaptureDataSheet sheet("My Very Own Property Sheet App",NULL,0);
sheet.m_psh.dwFlags |= PSH_NOAPPLYNOW;//hide apply button
m_pMainWnd=&sheet;
INT_PTR nResponse=sheet.DoModal();
return FALSE;

In the Capture Data Sheet

IMPLEMENT_DYNAMIC(CCaptureDataSheet, CPropertySheet)
CCaptureDataSheet::CCaptureDataSheet(UINT nIDCaption, CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(nIDCaption, pParentWnd, iSelectPage)
{
AddPage(&m_Page01);
AddPage(&m_Page02);
}

CCaptureDataSheet::CCaptureDataSheet(LPCTSTR pszCaption, CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(pszCaption, pParentWnd, iSelectPage)
{
AddPage(&m_Page01);
AddPage(&m_Page02);
}

CCaptureDataSheet::~CCaptureDataSheet()
{
}
BOOL CCaptureDataSheet::OnInitDialog()
{
BOOL bResult = CPropertySheet::OnInitDialog();
}

According to the article. The array I pass of handles to the WaitMultipleObjects should take care of that for me.

Thank you for the feedback. I appreciate the honesty. I will check on the article and work my way from there. thanks a million.

I am trying to follow this: [Creating Threads using the CreateThread() API](<a href=)[^]"> However I am having an issue, My thread is still running even though the main process id done. What I am trying to achive is a loop to create threads and wait for all the threads to finish the process before I run the same process again. My Issue is I get a message to say my loop is done, however the thread is still running. Could someone please shed some light.

DWORD WINAPI Thread_1(LPVOID lpParam)
{
int a =0;
char Temp[256];

{

pDlg->SetDlgItemText(nEid,Temp);
ProcessMessages();
}
return 0;
}

    CloseHandle(hThread\_2);
    //The aim is to wait for the unctions to finish before any of the threads start again

}
MessageBox("Done","Information",MB_OKCANCEL);

I get the messagebox, however the The second thread is still running.

I get this when I am exiting my application which is property sheet based? So why on Exit and not before?

Yes I did.

What does this message mean in a debug mode? First-chance exception at 0x5d0c373e in DemoKey.exe: 0xC0000005: Access violation writing location 0x004456ec. I get this when I am exiting my application which is property sheet based? :confused:What have I not done before exiting the application or is it Normal? Thank in advance

Thanks again. which is what I thought but wanted to be sure. I guess back to debugging and find out why I can't get the data from the second window. However, I should be able to use the same thread and pass the handle as a parameter? or am I better off creating multiple threads and dedicate each thread to a window for the lifetime of that particular window?

Hello, I am trying to capture a window from an external App Example Calculator. I am able to get the handle of the window. If the user opens a second instance, I am able to get that handle too using EnumWindows. Which means I have 2 handles for the 2 calculators. Short of using the Handle is there anything else that I could use to differenciate the 2 windows. I can't use the window title since they are both the same. Reason for asking: I know the handle gets reused, but is it possible for the handle to change after the window has been created or does it stay the same after creation? Yes, if I close the window, I know I will not get the same handle. Is it possible that If the user minimizes the window and activates it again, we get a new handle? If the handle changes during the lifetime of the window whats the best way of keeping track of that window? I have created a thread and am using the same function to handle capturing data from the 2 windows by passing the handle as a parameter. However, I can only get the data from one of the windows, or am I better off creating multiple threads which is what I was avoiding? Could someone please help.
