What reporting tool are you using?

if you mean relative to the exe, then use :

MyPath:=IncludeTrailingBackSlash(ExtractFilePath(Application.ExeName));
MyFile:=MyPath+'MyFile.Wmi';

if you want more clues than that you will have to tell us what properties of what objects you want to set in run-time

I uses Rave reports in my project, but I'm not following what you're talking about.
To set the report path at run time I use:
 RvProject1.ProjectFile := extractfilepath(Application.ExeName) + 'Print.rav';

i hope this helps

Hi Guys,
Sry for maybe not very clear explanation, I was in hurry.
Here is my situation:
I have got an application which user can install in directory of his or her choice.
I have solved the problem with ini files using the this:
ExtractFilePath(ParamStr(0)) - it gave me the possibility to check the application directory and to assure the appropriate path to files. I thought that is the end of my story but i need to change the path in Metafile, file link property  also. I can`t put there a static path becouse I`m not the fairy :) - user can choose the path, so I need to set this property on runtime.
Guys i have noticed that nobody reads the tags info in the questions - I have put there info that this is RAVE REPORTS 7.5 - object METAFILE and property file link -
I will check your suggestions and put an info up here in about 30 min.
I`m very grateful for you help.
BR

Additional info:
file link property is used in my app to show the created graph which is saved in chart.wmi file. I need to point this file in file link property.

 

by: epasquierPosted on 2009-11-03 at 14:09:09ID: 25734355

MyPath:=IncludeTrailingBackSlash(ExtractFilePath(Application.ExeName));
Metafile1.FileLink:=MyPath+'Chart.wmf';

Oh i know what you're talking about!
Pass the path as a parameter to rave
Then create an OnBeforePrint event in rave and pass the parameter to the FileLink property.
That's how I put images that are created dynamically at runtime into my rave reports.

1. Add the parameter name to your parameters list in Rave. To do this, click on your RaveProject, that's the first node on the right inside your Rave Project. Edit the Parameters property (on the left). This is a list of strings. Add pMyPath.
2. Inside Delphi, send the path to the parameter in rave, e.g.:
  rvproject1.SetParam('pMyPath', extractfilepath(Application.ExeName) + '\myFile.wmi');
3.  In your onbefore print in rave, link the FileLink to the parameter. You can either click on the MetaFile component, but it's recommended to click on the parent of the MetaFile component because it gets printed first, in fact it's even more recommended to print on the band/databand BEFORE that band, but in any case, click on the band, click on Events, choose the onBeforePrint event, and type:
MetaFile1.FileLink := RaveProject.GetParam('pMypath');

Don't forget to Compile the rave project and  save it.

Good luck
