Is this the only file I need ?

Hello world,

Now I wanna know if the vbrun50032.dll files is the only one I need for project ?

Depends on what type of program and what you are doing.
Usually, not always, if you are just making an exe then the msvruntimes are all you need...however, there are times, dependant on the controls used, that you need other files.
If you are making a distributation disk and use the Packaging and Deployment wizzard via addins it usually adds or tells you the files you need.

If you are using VB5 you can use the Application Setup Wizard to create just a dependancy (.dep) file which will list what DLLs are required.
