I want to have a datawindow that contains a different image for each row. I created a picture object and put it in the detail band. I also added a regular string column 'pic_object' (external datawindow).

What I want is something like this:

Row 1 dog.png

Row 2 cat.png

row 3 mouse.png

If I do this: dw_1.Object.p_1.Filename = 'C:\dog.png' it works but sets the picture image for all rows.

I then tried adding a compute column that has this as the expression bitmap( pic_object ). So I insert row one and set pic_object to 'C:\dog.png' thinking pic_object might display my picture but it doesn't work. 

 

Any help is appreciated.

Hi Robert;

  I just did a quick test using an external DWO and the "Display as Picture" property. Here is my test result ...

As you can see - no issues.

Regards ... Chris

I am a doofus:

s_pic = "C:home_hover.png'" (see the extra quote mark?) That's why it didn't work - works now. BTW - thanks to everyone here that takes the time and effort to help me out in all my questions. I really appreciate it and it save so much time and headache.

Just a heads up

- avoid hard coding paths to objects like images

- make sure you use a pbr to make sure they are included in you release

Hi Robert;

  What I do for this implementation in my DWO's is ...

  1. Add a regular column to the DWO that will contain the image name at runtime for each associated picture. That means that every row would have a different value (as you stated for example: Row 1 dog.png; Row 2 cat.png; row 3 mouse.png; ...)
  2. Set the DWO's column property "Display as Picture" to ON

HTH

Regards .. Chris

string ls_pic

ls_pic = "C:\home_nohover.png'"

dw_1.insertrow(0)

dw_1.SetItem(1, 'pic_object',ls_pic)

ls_pic = "C:home_hover.png'"

dw_1.insertrow(0)

dw_1.SetItem(2, 'pic_object',ls_pic)

This is my code but what am I doing wrong? Doesn't display an image in pic_object column. I set pic_object to display as picture - pic_object is string 50.

I create a compute field on the datawindow and use this expression:

bitmap(gf_bitmap(objtype))

objtype is a column name and gf_bitmap is a function object. It returns a string with the name of the bitmap file.
