Hey Comm-unity,
I'm working on a small challenge for myself in which I am trying to make a powerpoint from c# code. Everything works until my code tries to save the powerpoint, and then it throws the following error:
COMException

And here's the code that throws the error:
public class PowerpointCreator : MonoBehaviour
{
p.TextRange objText;
p.Application app;
p.Presentation pre;
p.CustomLayout c;
p.Slides slides;
p._Slide slide;
int slide_id = 1;
public int font_Size = 16;
public string font_Style = "Arial";
public string temp_save_path = "C:\\Users\\James\\Documents";
void Start()
{
app = new p.Application ();
pre = app.Presentations.Add (MsoTriState.msoTrue);
c = pre.SlideMaster.CustomLayouts [p.PpSlideLayout.ppLayoutText];
}
void CreateNewSlide()
{
slides = pre.Slides;
slide = slides.AddSlide (slide_id, c);
slide_id++;
}
void CreateHeader(string header, int fontSize, string font)
{
objText = slide.Shapes [1].TextFrame.TextRange;
objText.Text = header;
objText.Font.Name = font;
objText.Font.Size = fontSize;
}
void AddText(string text)
{
objText = slide.Shapes [2].TextFrame.TextRange;
objText.Text = text;
}
void ModifyTextBox(string text, int id)
{
objText = slide.Shapes[id].TextFrame.TextRange;
objText.Text = text;
}
void Add_Shape(MsoAutoShapeType type, float top, float left, float width, float height)
{
slide.Shapes.AddShape (type, left, top, width, height);
}
void Save()
{
pre.SaveAs (temp_save_path + "myPresentation.ppt");
}
void AddTextBox(float top, float left, float width, float height)
{
slide.Shapes.AddTextbox (MsoTextOrientation.msoTextOrientationHorizontal, left, top, width, height);
}
void CloseAndQuit()
{
pre.Close ();
app.Quit ();
}
public void CreatePresentation()
{
CreateNewSlide ();
CreateHeader ("Header", font_Size, font_Style);
AddText("Text");
AddTextBox(50.0f, 450.0f, 250.0f, 100.0f);
ModifyTextBox("Text Box", 3);
Add_Shape(MsoAutoShapeType.msoShapeRectangle, 50.0f, 150.0f, 250.0f, 100.0f);
AddTextBox(500.0f, 150.0f, 250.0f, 100.0f);
ModifyTextBox("Text Box Number Two", 4);
Save ();
CloseAndQuit ();
}
}
Thanks everyone!
