<pre wrap="">Thank you for your help Bram, it is very nice !
So, I did a list of return values of functions used in my code :
DBFCreate returns 375328,
SHPCreate = 379776,
DBFAddField = 0,
DBFWriteStringAttribute = 1,
SHPCreateSimpleObject = 410704,
SHPWriteObject = 0.
I hope you could tell me what these figures mean... And do you know where
could I find documentation about shapelib ?
Thank you again for your help
Romain.

<pre wrap="">The extension has nothing to do with it. At worst, it would create
something like test.shp.shp.
As no files AT ALL are created, the problem probably is within DBFCreate
and SHPCreate, as they should create file files straight away, even
without the data being added. Please, check the return values of
DBFCreate and SHPCreate. Are they null? Probably they are, and that
means the creation of the files simply fail. And thus everything else
fails too.
Try a more simple filename like just "test".
Are you prepared to step through the code in a debug session. Maybe you
can figure out what exactly fails ...
Good luck =)

<pre wrap="">Hi Vassilis,
I tried what you told me too, but it still not work. No error, but no
files... It's hopeless !! ^^
I think there is something wrong against me with this library !!!
Thank you for your reply !

My code :
//création du dbf
IntPtr ptrDBFCreate = shpFile.DBFCreate(@"\SD-MMCard\TestParcelle\test");
//création du shapefile
IntPtr ptrSHPCreate = shpFile.SHPCreate(@"\SD-MMCard\TestParcelle\test",
ShapeFile.ShapeFile.ShapeType.Point);
//nouvelle colonne dans le dbf
shpFile.DBFAddField(ptrDBFCreate, @"\SD-MMCard\TestParcelle\test",
ShapeFile.ShapeFile.DBFFieldType.FTString, 255, 0);
//écriture de la valeur liée au futur shape
shpFile.DBFWriteStringAttribute(ptrDBFCreate,
shpFile.DBFGetRecordCount(ptrDBFCreate), 0, "to");
//création du point
double[] x = new double[1];
double[] y = new double[1];
double[] z = new double[1];
x[0] = 803606;
y[0] = 803606;
z[0] = 0;
IntPtr psObject =
shpFile.SHPCreateSimpleObject(ShapeFile.ShapeFile.ShapeType.Point, 1, x,
y,
z);
//écriture du point dans le shape
shpFile.SHPWriteObject(ptrSHPCreate, -1, psObject);
//fermeture du dbf et du shapefile
shpFile.SHPClose(ptrSHPCreate);
shpFile.DBFClose(ptrDBFCreate);
