hi again,

here is my code :
int n = dsCfg.tblCfg.Columns.Count;
Object[] ao = new object[n];
ao[0] = "SETTINGS";
ao[1] = 0;
ao[2] = some value
taCfg.Update(dsCfg.tblCfg); // -> throws exception : cannot insert duplicate PRIMARY KEY

tblCfg has 6 columns : 0=nchar(10), 1=int, all others are type sqlvariant; 0 and 1 build PRIMARY KEY

so if it can't insert why doesn't it up ?
any help (except try this... (means i don't want to rewrite the project)) appreciated

thanks in advance

I think that message is trying to tell you something.

As Richard said, you cannot insert a duplicate primary key. That is your answer, you are attempting to do that and you cannot.
