Make sure you get the necessary dll first.
%programfiles&\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll
private void InitializeAdobe(string filePath)
{
try
{
this.axAcroPDF1.LoadFile(filePath);
this.axAcroPDF1.src = filePath;
this.axAcroPDF1.setShowToolbar(false);
this.axAcroPDF1.setView("FitH");
this.axAcroPDF1.setLayoutMode("SinglePage");
this.axAcroPDF1.Show();
}
catch (Exception ex)
{
throw;
}
}
When form closes.
this.axAcroPDF1.Dispose();
this.axAcroPDF1 = null;
