Hi, I have an application built on VS2005 which uses a static library built using VS6.0. I have noticed an issue of incorrect function getting called from a static library linked at compiled time. Note that this static library was built using Visual Studio 6.0. Whereas my application which is using the static library for linking at compile time is built using VS2005. At run time, I see that incorrect/different functions are getting called rather than the ones which are supposed to get called. To solve this issue: I rebuilt the static library (.lib) using VS2005. Then this newly built static library was used for compilation along with my application on VS2005. Then the functions are getting called correctly. I have 2 questions here: :confused: 1) This means that if there is any static library built with older version of VS6.0, then it will not work correctly with an application built with VS2005. We need to rebuild it with the same compiler as the application is built with. Is this true? why this happens in case of static libraries? 2) If above point-1 is true, then isn't it necessary to rebuild DDLs also with VS2005? If no, then why it is ok that a DLL built with older version of compiler works fine with application built with newer compiler version?

It is working fine now. I unregistered the ocx control, then rebuilt the control and then registered it with regsvr32.exe. Now OnInitDialog of CPpSelectDn is getting called. Also, the UI controls for LDAP directory browse are shown correctly on the page. It looks like earlier it had old incorrect version of ocx file registered, which needed unregistering and reregistering the new one. ;)

Here is what I did with VS6.0: - As I mentioned earlier, it was working fine with VS6.0. So What I did now is , I created a fresh VS6.0 setup on a new machine and built the code. But when I tested, again I was facing same display problem as I was getting with VS2005. However, I saw below warnings in the VS6.0 output window:

CoCreateInstance of OLE control {395262A9-51B1-11D2-BA1B-00A02489AC7A} failed.

Result code: 0x800401f0
Is the control is properly registered?
Warning: CreateDlgControls failed during dialog init.

So I registered the IsoDirB.ocx file using regsvr32.exe manually. Then when I tested the application with VS6.0, it worked correctly and the UI problem with Directory browser display was not there and everything worked just nicely. So this meant that if IsoDirB.ocx control is not registered, then I see UI problem with Directory browser display. ------------------------------------------------------------------- From above findings, I also registered the IsoDirB.ocx file using regsvr32.exe manually on VS2005 machine too. It didn't give any error when I registered IsoDirB.ocx using regsvr32.exe on VS2005 machine. Then when I tested the application. However, I am still seeing the same display problem with Directory browser display with VS2005. I see below warnings in the VS2005 output window:

'mm.exe': Loaded 'C:\Program Files\CriticalPath\Manager\IsoDirB.ocx', No symbols loaded.
First-chance exception at 0x77fac57c in mm.exe: 0xC0000139: Entry Point Not Found.
'mm.exe': Unloaded 'C:\Program Files\CriticalPath\Manager\IsoDirB.ocx'

I am not sure how much important/relevance above warning has with the UI problem; but this might be important. I remember I made changes in build of IsoDirB.ocx code project and not sure if it is causing this first chance exception. Any inputs on investigating about this "Entry Point Not Found" warning are highly appreciated.

I debugged. I see that it calls 'INT_PTR CPropertySheet:: DoModal()' which internally calls CPropertySheet::OnInitDialog(). Here is the stack trace in case this helps you in pointing out any clues: Code:

I also saw that CPropertyPage::OnSetActive() was called by CPropertySheet:: DoModal(). As can be seen above, CPropertySheet::OnInitDialog() is getting called. However, OnInitDialog function of CPpSelectDn class is not getting called.

I looked at it. But it has Customized BEGIN_TEMPLATE_MESSAGE_MAP only for VC7. It doesn't have mention of Customized BEGIN_TEMPLATE_MESSAGE_MAP for VS2005/VC8.

Hi, I am getting below compiler error on Visual Studio 2005: isodirbrowserlistctrl.cpp(46) : error C2906: 'const AFX_MSGMAP *CListDataCtrl<B,T>::GetThisMessageMap(void)' : explicit specialization requires 'template <>' with [B=CListCtrl,T=CBrowserListCtrlData Here is the code with .h and .cpp files. This code used to compile and run fine on Visual Studio 6.0. I guess I need to use BEGIN_TEMPLATE_MESSAGE_MAP. But BEGIN_TEMPLATE_MESSAGE_MAP can not handle more than one template arguments. In my case, there are 2 template arguments.

GenUtilLoadPropPage loads the Property Page having pageSelect.IDD. When I debugged, it was able to find the resource needed and FindResource() was successful. Wonder why it still does not call the OnInitDialog of CPpSelectDn class though.

Hi, I am porting code from VS 6.0 to VS2005. However I am seeing that OnInitDialog() function is not getting called from DoModal() in VS2005. I already tried adding breakpoints and messagebox to see if OnInitDialog function of CPpSelectDn class is getting called. However I found that it is not getting called.

In the following code snippet which delete should I use?? char *ptr1=new char[100]; char arr[10]="abcdefghi"; strcpy(ptr1,arr); //delete ptr1; delete []ptr1; Should I use delete ptr1; or delete []ptr1;

Why Virtual constructors are not allowed in C++??

Can anybody tell me the difference between Abstract Base classes vs Interfaces??
