I have a requirement to modify the ms project file (.mpp) using C#.net.
I have done with all the things, the only thing remaining is to modify the TimescaleStart date of MPP file using C#.net. I need to set the user defined date.
How can i do that?
Following is my code:
Microsoft.Office.Interop.MSProject.Application app = new Microsoft.Office.Interop.MSProject.Application();
app.DisplayAlerts = false;
app.AskToUpdateLinks = false;
app.FileOpenEx(
strFilePath + "test.mpp",
false,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
PjPoolOpen.pjPoolReadWrite, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
Microsoft.Office.Interop.MSProject.Project pj = app.ActiveProject;
object objDate = dt.Date;
app.TimescaleStart = objDate;
Got Error as
Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH))
on Following line:
app.TimescaleStart = objDate;
TimescaleStart
is a read-only property which returns the date that the timescale starts in the current view.
If you want to scroll the view so that it starts at a certain date, find a task with a start date on or close to your target date, select it and invoke the GotoTaskDates
method of the application object. For example:
app.Find "Start", "is greater than or equal to", "1/1/2014", Type.Missing, Type.Missing, Type.Missing, Type.Missing
app.GotoTaskDates
Update:
If you are using Project 2010 or later, you can also use this method:
app.PanZoomPanTo (objDate)
Could it be that you're actually trying to change the project start date?
If that's the case, try using the "ProjectMove" method. reference here and here .
If you really really want to change TimescaleStart, it looks like you are out of luck.
