Experience with Net Express 5.0 under Windows 11?

Hi, 

although Net Express was no longer supported under Windows 10, we had no problems there.

Under Windows 11 we unfortunately get crashes (C++ runtime exception) when we use the Windows API call SHBrowseForFolder.

It seems that the crash depends on when MFOLECL.DLL is loaded.

Has anyone already had such experiences?

Regards

Wolfgang

This will not works and not supported from MicroFocus!

MF declare that only Netexpress 5.1 will work on Windows 10.
Can you publish what you have done to have Netexpress 5.0 on Windows 10, 32 or 64 bit, wich version of Win10?

Thanks for answer!

Yes we missed all a functional version of Netexpress 6.0 with the state of vc7.0 (without dotnet)

On windows 10 we have no problems with Netexpress 5.0. On Windows 11 we were able to work around the problems by adjusting the call order of DLLs.

Hi Wolfgang,

What do you mean with "adjusting the call order of DLLs"?

Can we stay in contact to exchange our experience? Then send me a private message!
I use the same code for Win7, Win10 and now Win11!

We have observed that it makes a difference when SHBrowseForFolder is called. That's why we make a dummy call to SHBrowseForFolder when the program starts to avoid problems later.

Hi Wolfgang Köhnke

We found that calls with UNC names (\\\\hs-xy\\c$\\file.* work fine, but not N:\\file.*

May I ask what the dummy call you mentioned looks like when you start the program? Code ?

Many thanks for the help.

01  pfad      pic x(255) value "c:\\xyz"

call winapi SHBrowseForFolderA using pfad return-code

or a little bit others...

Please take care to pass in the right information to an API, this API takes a pointer to a structure called BROWSERINFO which contains pointers/function pointers.   

Any API may crash or cause stack corruption if you pass junk into it.   

In this example, you end up creating pointer in the structure that has the hex value 0x20202020 due to pfad containing spaces.

PIDLIST_ABSOLUTE SHBrowseForFolderA( [in] LPBROWSEINFOA lpbi );

Netexpress 5.0 works fine on Win10 and Win11 last edition without any problems!

This for information and it is not ok if MF refuse support on this os! It is the same netexpress version running also under Win7.

Not everybody want to use visual studio or eclipse! We need a netexpress 7.0 with the same modules for VS7.0 (without .net or eclipse)

Thanks, this can be read by microsoft, but now the code in MF-Cobol!

Thanks for your great help!

Good afternoon,
I have the same problem on windows 11.
if I run SHBrowseForFolder at the beginning of the program,
it stops giving the error and everything works fine in windows 11.

Could you please provide me with the code used with SHBrowseForFolder, without it opening the request window.

Thanks in advance for your help.

not a problem with netexpress 5.x, also VC8.x tested on win7, win10 win11 always latest edition
