Folks,
I have a VERY OLD legacy app that I'm trying to compile under VS 2008 (I am NOT an MFC developer at all).
I am running into build errors on things like:
<br />
template <> void AFXAPI ConstructElements <SubjectUsage> (SubjectUsage * pSubName, int nCount)<br /> NOTE: Edited this to correct the line
ERRORS for this is:
C2143 Syntax error: missing ";" before "<"
C2182: "ConstructElements: illegal use of type 'void'
C2988: unrecognizable template declaration/definition
I know NOTHING about the AFXAPI, but the file does have an
<code>#include <afxtempl.h> </code>
Any help greatly appreciated, and in general, any words of wisdom from moving from VC++6 to VS2008?

There appears to be something missing from this statement. Try clicking the "Do not interpret HTML..." checkbox, and use the Verify button.

It looks as though the compiler does not know what SubjectUsage is.

Well, I didn't include all of the code, but the SubjectUsage class is defined right above this line in the file, so that shouldn't be an issue.
This code DOES compile in Visual C++ 6.0. I'm sure there must be differences with C++ and with the MFC supplied with VS 2008 that is causing this -- not sure if there are any project switches to set for compatibility?
Also, the CORRECT statement that has the errors is:
template <> void AFXAPI ConstructElement <SubjectUsage> (SubjectUsage * pSubUsage, int nCount)
Sorry about that!

Thanks -- I did read those pages, but not a lot of info on using old MFC with VS 2008.

Yes but old MFC is just C++. Stuart has provided the pinpoint documentation for you so you can move on. If you find other problems they will be similar because VC6 did not fully implement the C++ Standards. I don't believe 2008 does either but it implements much more which can produce compiler errors in old code due to the compiler enforcing more standards. Each version of VC since 6 has been more compliant so as in this example the documentation might be version specific since it was changed in a specific version.

Thanks -- yeah that link really helped!
I guess I was hoping that there would be some sort of compatibility mode setting for the compiler/project to allow this to work with minimal change, but I don't think that's possible!

This page[^] tells you what to do - basically, don't use ConstructElements any more!

Thanks -- VERY helpful!!!

hi there,
I have compiled a string table and some of the strings I need to assign to a char* variable, how can I do it?
Thanks

What about LoadString [^] function?

On the picture control ,I mean to move the rectangle through the mousemove.
how to make it? the picture control contains a picture and a small rectangle is on it.

If you use of CStatic you can derived your class of it and then declare WM_MOUSEMONE on it or you cna do it of your main class.

In this days i'm writing a software to use for recovery PC. My software is complete but i need a progress bar moves during file extraction, i am trying but in 10 days nothing. How i can solve??? i post only the complete wim code. Please help me

with this code all is blocked if i remove the item "Progress->SetPos(percent);" all go ok but without progress bar moving.

You need to put your lenghty processing in a separate thread. Here[^] is an excellent article that will get you started about threading.

Hi i have created a Dialog which contains the two buttons OK and CANCEL . But when i resize the dialog these button stick to their original position and does not change . I want these buttons to be on Botton Right Corner of my dialog . In my code i have done this
.
AddAnchor (IDC_HPCR_WO_OK ,BOTTOM_CENTER );
AddAnchor (IDC_HPCR_WO_CANCEL ,BOTTOM_LEFT );
Please provide any comments on this

Which library are you using, because there's no such support as AddAnchor in the MFC ?

Are you using CResizableDialog[^]? You could use the message board at the bottom of the article to ask your query. The author of the class himself may respond to you in that case.

Hi ,
Yes I am using CResizingDialog . Now what i did is i have writte a message handler
MESSAGE_HANDLER( WM_SIZE, OnSize )
but i didnt provide its implementation. My class is derived from CResizingDialog . Now buttons are changing their position as i required. But still not understood how it is working. Is it calling CResizingDialog :: OnSize () in this case ..?

Hi All
How can i set dialog size at the run time?Plz help me

If you plan to have controls on your dialog and resize or move them based on the size of the dialog you may want to use a layout library like this one: CResizableDialog[^]

Have you looked at SetWindowPos() or MoveWindow()?
