This is a similar problem to the post on ps3000_get_unit_info. I have tried to use this function with VB6 and VB.net with no success, it just causes an application crash. This applies even when I use the code snippet shown in the ps3000 case. I have tried with both fixed and variable length strings.

I suspect it is to do with the way c and vb handle strings differently.

Anyone got any workable suggestions, please?

Hi try the file attached. It has an example in excel which works.

Kind regards

Ziko,

The attached file does not contain an example of using ps2000_get_unit_info, only the procedure declaration. I have no problems with the other functions and can use them happily, but get_unit info always crashes.

Hi yeah sorry just realised. It does contain the decleration however it needs to be modified. The following should be used:

Declare Function ps2000_get_unit_info Lib "ps2000.dll" (ByVal handle As Integer, ByVal str As String, ByVal lth As Integer, ByVal line_no As Integer) As Integer

If ByVal or ByRef are not chosen VB will by default select ByRef.

Please find a modified version of the example.

Kind regards
