How to read VB's udt files?

In VB you can write a whole UDT into a file. Have anybody have experience in reading the udt files in purebasic?

WriteData(FIO, my_udt, sizeof(my_udt)
ReadData(FIO, @my_udt, sizeof(my_udt)

Ah, thanks for the information!
I didnt know Fred cloned the VB's UDT writing and reading exactly.
I'll check that out as soon as I get home.

UDT PB equivalent is the Structure, whatever language you use, writing structure is always done this way

Okay then .. I'll give it a shot to read a vb udt file. If it doesnt work, I'll post both the code for vb and pb

This doesn't work for Strings! Only the useless Pointer is written

Hehe, well er... Cant be entirely useless as vb must be able to read the string somehow.

You can use FixStrings for that
Code: Select all
Structure test
text.s{255}
EndStructure
test.test
test\text = "Holla, purebasic rulez"
File = CreateFile(#PB_Any, "C:\test.dat")
If File
WriteData(File, @test, SizeOf(test))
CloseFile(File)
EndIf

Yes, but that wasnt my question that started the thread. I am trying to read a udt file that was created in VB.
