National Instruments 320685D-01 Necessary Files for Using DLLs Created in Windows 95/NT, Location of Files on the Target Machine for Running Executables and DLLs

Chapter 7 Creating and Distributing Standalone Executables and DLLs

National Instruments Corporation 7-9 LabWindows/CVI Programmer Reference Manual

Windows 95/NT, the Run-time Engine consists of multiple files, including three DLLs

and the low-level support driver. Under Windows 3.1, the Run-time Engine is an

execute-only version of the LabWindows/CVI environment. Under Sun Solaris, the

Run-time Engine is a shared library

•UIR files—The User Interface Resource files that your application program uses. Use

LoadPanel and LoadMenuBar to load these files.

•Image files—The graphical image files that you programmatically load and display on

your user interface using DisplayImageFile.

•State files—The user interface panel state files that you save using SavePanelState

and load using RecallPanelState.

•DLL files—(Windows Only) the Windows Dynamic Link Library files that your

application program uses.

•PTH files—(Windows 3.1 Only) specify the location of DLL files when you want to

load the DLL from a special directory, or indicate that you want to find a DLL using

the standard Windows DLL search algorithm.

•External .lib or .a files —Compiled 32-bit .lib files on the PC or .a files under UNIX

that you load using LoadExternalModule and that you have not listed in the project.

•External .obj or .o files—Compiled 32-bit .obj files on the PC or .o files under UNIX

that you load using LoadExternalModule and that you have not listed in the project.

•Other files—Files your executable opens using open, fopen, OpenFile, and so on.

Necessary Files for Using DLLs Created in Windows 95/NT

Under Windows 95/NT, you can distribute DLLs that use the LabWindows/CVI Run-time

Engine. As in the case of standalone executables, you must distribute them along with the

LabWindows/CVI Run-time Engine.

Location of Files on the Target Machine for Running Executables and DLLs

To assure proper execution, it is critical that all files associated with your executable program

are in the proper directories on the target machine. On the PC, you specify these files in a

relative directory structure in the dialog box that appears when you select Create

Distribution Kit from the Build menu of the Project window in LabWindows/CVI. Refer to

the LabWindows/CVI User Manual for details. This section describes the proper location of

each of the files shown in Figure 7-1.
