Hi
I'm trying to extract the Product code from an MSI using C# (this is for a
custom msbuild task I'm writing).
I'm using the following definition for P/Invoke
[DllImport("msi.dll", CharSet = CharSet.Unicode)]
static extern Int32 MsiGetProductInfoFromScript(string scriptFile,
StringBuilder product, ref ushort langId, ref uint version, StringBuildername,
ref uint nameSize, StringBuilder package, ref uint packageSize);
I keep getting a return code of 1603. Everything looks OK, but I'm starting
to suspect that the script file I'm passing is causing a problem,
ushort langId = 0;
uint version = 0;
uint packageSize = 10;
uint nameSize = 40;
StringBuilder product = new StringBuilder(40);
StringBuilder package = new StringBuilder(40);
StringBuilder name = new StringBuilder(100);
int e = MsiGetProductInfoFromScript(@"C:\Test\Test.msi", product, reflangId,
ref version, name, ref nameSize, package, ref packageSize);
Am I even calling the correct method? The only other option I can think of
is to open the DB and go through the whole SELECT * FROM Property and then
extract the product code from the returned view.
Thanks,
Jacques
