How do I detect the DLLs required by an XBase and eXpress application?

[PedroAlex]

HI,

How do I detect the DLLs required by an application?

Do you have any trick to easy identify the dll dependency of an xbase exe?

Many Thanks

Hi, Pedro.

Doing this from inside the application is possible, but a little complicated. From the outside, you may try:

- The tool "dependency walker": https://www.dependencywalker.com/
- The tool "Process Explorer" from the Microsoft Sysinternals Suite: https://learn.microsoft.com/de-de/sysin ... s-explorer
- Powershell

Hi Tom.
Many Thanks for reply.

The situation is :
I Have a Program.exe develloped in xBase.
But I do not know what dlls i need to run this exe.

Obviously, if I try to run the exe I will know step by step.
What I am looking for is a way to identify which DLLS I need for this exe in advance. And provide only the strictly necessary DLLs.

regards

Hi, Pedro.

It should be easy.

All DLLs you find in the "Runtime"-folder of your Xbase++-distribution should be included. If you use Xb2.Net, include xb2net.dll, if you use sqlexpress, add sqlexpress.dll, if you use eXpress++, at least add dclipx.dll. Put all these and your exe in a folder of a computer with no pathes to Xbase++ or any other tools and start it from the command line. It will tell you which DLLs are missing.

I use the CHK4DLL.EXE utility: http://bb.donnay-software.com/donnay/chk4dll.exe

Example:

CHK4DLL XDOT.EXE will produce the following output :

XCHK4DLL Version 1.0 - DLL load check.

Processing file xdot.exe
DCLIPX.dll -> C:\expd20\bin20\DCLIPX.dll can be loaded.
DCLIP1.dll -> C:\expd20\bin20\DCLIP1.dll can be loaded.
DCXML.dll -> C:\expd20\bin20\DCXML.dll can be loaded.

XPPDBGC.dll -> C:\Program Files (x86)\Alaska Software\xpp20\lib\XPPDBGC.dll can be loaded.

Caveat: Only those DLLs that are statically referenced (via your XPJ file or a #Pragma Library() statement in your source code) will be listed.
For example, if you use DllLoad() in your application to dynamically load a DLL, it will not be listed.

With release 2.00.2413 of Xbase++ (2.0), Alaska provides a tool (CLI) named "XPPDH.EXE", which will list all DLLs used by any Xbase++-binary, which can be an EXE or a DLL.
