Hi,

I have created a custom appwizard. I need to know how to update the fields on the general tab of the Project Settings dialog. I have been able to set the options on the Link tab using link.exe as a parameter and cl.exe as a parameter on the C/C++ tab.

The following is used to set the MFC usage on the General tab of the Project Settings

CComPtr<iconfiguration> pConfigs;
VARIANT dummy = {0};

pConfigs->AddToolSettings(L"mfc", L"0", dummy);

Any suggestions welcome.

Thanks in advance.

There's a fair amount of sample code out - google is your friend. Here's code from the VCF(http://vcf.sf.net) project's VC6 App Wizard.
http://cvs.sourceforge.net/viewcvs.py/vcf/vcf/build/vc60/add-ins/VCFAppWiz/[^]

If you have a look in http://cvs.sourceforge.net/viewcvs.py/vcf/vcf/build/vc60/add-ins/VCFAppWiz/vcfwizardAw.cpp?rev=1.15&view=auto[^] you can see in CVcfwizardAppWiz::CustomizeProject(IBuildProject* pProject) where all sorts of different configuration settings are changed.

Using resources from a dll in an exported class

Jon Hulatt20-Oct-04 1:42

Hi,

I have an MFC extension dll, which exports a class. The class is actually CStatic derived and uses several instances of the CImageButton from this site.

That class is exported from the dll using MFC's AFX_EXT_CLASS macro, and imported into my main exe with the same.

I want the CImageButton's in the dll-class to use bitmap resources from the DLL. But, in the code for CImageButton, it uses ::LoadBitmap to actually load the resource, the first argument of which uses AfxGetInstanceHandle() to get the HINSTANCE of the app. Of course, AfxGetInstanceHandle returns the HINSTANCE of the exe, so it all goes pete tong.

The only workaround i've found it to use a global variable of type HINSTANCE in the dll, and in DllMain to set the global var to store the HINSTANCE. Then use that HINSTANCE in place of AfxGetInstanceHandle.

Whilst it works, it doesn't seem "right"- it seems a bit of a bodge.

Is there a better way?

Thanks

Jon

I *think* you want to look into AFX_MANAGE_STATE(AfxGetStaticModuleState( )) - this will switch the state for you. You would put this call at the beggining of your function, BEFORE any resource calls (like LoadImage/LoadString, etc) are made.
It's possible you may want to use something other than AfxGetStaticModuleState() - look it up in MSDN - there are other variations on it if I remember right.

is that a real buld/light/LED ? if so, there should be an API with some kind of external domotic controller ?

if not, what exactly you want to do ?

I send data to device.I send 1.
I use this code.
int i=13; //enter key
CString mm=i;
CString mmm=m_text+mm;//m_text=1

if(!(port.WriteString(mmm)))
{
MessageBox("Cannot Write to Port","Error",MB_OK); port. ClosePort();
}
else
{
MessageBox("Send by "+mmm,"Success",MB_ICONINFORMATION); }

Function is work. But PLC is not translate.
I want to know how to get send data.

Spin Control with Real Numbers

19-Oct-04 21:56

Using a Spin Control with real numbers, but have a problem when the Up or Down spin is held down for a while.
The data increments/decrements but after a period (around 30 ~ 100) the sign of the data changes.

I am using my own routine to handle the increments/decrements via OnDeltaposSpinNewdata. The Autobuddy is set to false and the Set Buddy Integer is set to true (tried false but still the same).

void CEditDlg::OnDeltaposSpinNewdata(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
   LPNMUPDOWN pNMUpDown = reinterpret_cast<LPNMUPDOWN>(pNMHDR);<br />
   // TODO: Add your control notification handler code here<br />
	<br />
   int incrementValue;<br />
<br />
   m_fSpinIncrement = m_fScalingFactor;<br />
   if(pNMUpDown->iDelta == -1)	// Increment the value<br />
   {<br />
      IncrementData(m_fSpinIncrement);<br />
   }<br />
   else	// Decrement the value<br />
   {<br />
      DecrementData(m_fSpinIncrement);<br />
   }<br />
   *pResult = 0;<br />
}

C++ Runtime - different Instance in DLL?

peterchen19-Oct-04 21:53

19-Oct-04 21:53

I am not sure about this: When I have a DLL and an EXE compiled with VC, and the EXE loads the DLL, does each have it's own instance of the C runtime (i.e. the global variables like stdin, stdout, the heap, etc.)? Does this depend on compile settings?

TIA

Yes, that is why you should avoid using free() and the delete operator on pointers received from a dll.
