Hi all,
I have the following function in my VC6 project:
<br />
LPSTR getFieldName(int index)<br />
{<br />
return (index < 0 ? "abcd" : SysAllocString("Newstring")) ; <br />
}<br />
It runs well in VC6 if I give the preprocessor macro OLE2ANSI.
When I convert the same project to VS.Net 2003, It starts giving errors in atlconv.h. So I had to remove the OLE2ANSI macro from preprocessor definitions.
Then it give the error:
<br />
c:\src\INCLUDE\OIP.CPP(123) : error C2664<br />
: 'SysAllocString' : cannot convert parameter 1 from 'char *' to 'const OLECHAR*'<br />
It gives the same error in VC6 with out the OLE2ANSI macro.
Is there a macro in .Net that can be used instead of OLE2ANSI in VC6?
Any idea how to solve the issue?
thanks...

What you try to do man???
LPSTR getFieldName(int index)
{
return (index < 0 ? "abcd" : SysAllocString("Newstring")) ;
}
This is totally stranger code i suppose
SysAllocString - allocated BSTR - BSTR is OLECHAR* olechar is WCHAR or CHAR (depend on macro definition OLE2ANSI and system).If you wont to return just LPSTR why you don't do this
return (index < 0 ? "abcd" : "Newstring") ;
and in any way when you allocate string by SysAllocString you shoul remove one by calling SysFreeString but when you return some constant string you don't care about this at all.

I am converting a VC6 project to vs.Net 2003
This is some part of the code that works perfectly fine in vc6 and giving the error in vs.Net.
I don't want to change the code that is tested and working.
Why is the same code giving error in vs.Net?
Thanks a lot for your reply...

Hello,
Can I read function signature from a flat DLL without TLB or LIB extension? Actually, I can read function name but not its parameters from a DLL. What do you suggest about it? Thank you.

I'm trying to capture the whole screen, paint it in my fullscreen window, then add effects to it (transitions and such).
I have a fealing I have to use CreateCompatibleDC but I can't figure out where.
Here is a simplified version of what my code looks like:
INT ScreenWidth = GetSystemMetrics(SM_CXSCREEN);
INT ScreenHeight = GetSystemMetrics(SM_CYSCREEN);
HDC DesktopDC = GetDC(0);//I do this before my window is displayed
HDC MyDC = GetDC(hWnd);//hWnd Is my window
BitBlt(MyDC,0,0,ScreenWidth,ScreenHeight,DesktopDC,0,0,SRCCOPY);//Trying to cover my window
Any one care to help? (WIN32 API only please)
Also could you show me how to double buffer for flicker free drawing?
P.S. GDI is tough

hi Jim - my internet is really slow, I missed your posting, so I have just posted a similar question!
I am trying to log some information when my program exits, which works fine with a normal exit, but I can't get it to work when the user shuts down Windows. Even Notepad knows when Windows shuts down, and asks about saving unsaved work, so it must be possible!
I'll let you know if I solve the problem!

See these messages:
WM_QUERYENDSESSION
WM_POWERBROADCAST
WM_POWER
WM_ENDSESSION
Some others to consider regarding changes to system state:
For Terminal Services: WTSRegisterSessionNotification
If you have open files: WM_DEVICECHANGE
If program is dependent upon screen resolution: WM_DISPLAYCHANGE
System settings have been modiifed: WM_SETTINGCHANGE WM_WININICHANGE
|
|
|
|
|
Thanks - WM_ENDSESSION appears to be the important one for me, but I will look at using WM_POWERBROADCAST and WM_POWER as well.

I can't really think of a better forum for this, so here we go...
Using VS NET IDE, Setup Project, does anyone know of a way to either modify the installation folder dialog or create a new one, so that the user can choose 2 install directories?
For example, 1 will be c:\program files\my company\my app
and 2 will be c:\program files\my company\common files
or something like that. Any ideas?
Rock!
