Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • Calculated image field on report?

    I am wanting to put a calculated image field on report? Is it possible?

    Any sample code?

    Re: Calculated image field on report?

    Not sure what your intent might be.

    You can choose to have an image on a form an have it loaded from a file. If you change the image by changing the file referenced on the form, the image on the form changes the next time the report is opened.

    IOW, image file name is c:\temp\abc123.jpg. If you go to the c:\temp directory and modify the image or save another image to the directory with that file name, that will be the image shown on the form.
    There can be only one.

      You can also code the onprintinit event to set the name you want.


      topparent:bitmap_object_name.Bitmap.Filename = "c:\temp\gold-star-graphic small.jpg"
      There can be only one.

        Re: Calculated image field on report?

        Great! Thanks. Here what I am thinking of doing.

        Since my parent record has multiple image records, I was thinking of updating the current table with the image data.




        Code:
        dim filename as C
        dim newfilename as C
        dim name_ext as C
        dim defdir as C = "L:\PRODUCTIMAGES"
        filename = ui_get_file("Select File", "jpg(*.jpg)", defdir +"\*.*")
        dir_create_recurse("L:\PRODUCTIMAGES\\"+alltrim(imagecat.value)+"\\"+alltrim(imagesubcat.value)+"\\"+alltrim(vendor.value)+"\\"+alltrim(Famiily.value))
        newfilename = "L:\PRODUCTIMAGES\\"+alltrim(imagecat.value)+chr(92)+alltrim(imagesubcat.value)+chr(92)+alltrim(vendor.value)+chr(92)+alltrim(Famiily.value)+chr(92)+trim(imagesku.value)+"_1.jpg"
        file.copy(filename,newfilename)
        
        name_ext = file.filename_parse(newfilename,"NE")
        
        
        record_number = current_record_number()
        query.filter = "recno() = " + record_number
        query.order = ""
        
        
        dim tbl as P
        tbl_src= table.current(1)
        tbl_dest = table.open("productimages")
        	tbl_dest.delete_range("Productimagename="+quote(name_ext))
        	tbl_dest.enter_begin()
        	tbl_dest.id = imageid.value
        	tbl_dest.Productimagename = name_ext
        	tbl_dest.Productimageindv = image_filename_encode(newfilename)
        	tbl_dest.enter_end(.T.)
        	tbl_dest.close()
        Here I am updating the child table. But I would like to update the main table one field. Is my code correct?

        Code:
        dim tbl as P
        tbl_dest = table.current(1)
        	tbl_dest.enter_begin()
        	tbl_dest.Productimageindv = image_filename_encode(newfilename)
        	tbl_dest.enter_end(.T.)
        tbl_dest.close()
        Since I will be sitting on this record do I need to open the table again?

        Thanks for the help.

          Still no clue what you're doing or what any of that has to do with a report.
          There can be only one.

            Hi Stan:

            I think rather than having a calcuated image on report, I thought it would be better to update the parent image field when user is uploading images.

            This is how I am wanting to you but failing (red marks).

            I have a form where user upload images (code below). What I would like to do is update the parent image field when user load the first image.

            Code:
            dim filename as C
            dim newfilename as C
            dim name_ext as C
            dim defdir as C = "L:\PRODUCTIMAGES"
            filename = ui_get_file("Select File", "jpg(*.jpg)", defdir +"\*.*")
            dir_create_recurse("L:\PRODUCTIMAGES\\"+alltrim(imagecat.value)+"\\"+alltrim(imagesubcat.value)+"\\"+alltrim(vendor.value)+"\\"+alltrim(Famiily.value))
            newfilename = "L:\PRODUCTIMAGES\\"+alltrim(imagecat.value)+chr(92)+alltrim(imagesubcat.value)+chr(92)+alltrim(vendor.value)+chr(92)+alltrim(Famiily.value)+chr(92)+trim(imagesku.value)+"_1.jpg"
            file.copy(filename,newfilename)
            
            name_ext = file.filename_parse(newfilename,"NE")
            
            
            record_number = current_record_number()
            query.filter = "recno() = " + record_number
            query.order = ""
            
            
            dim tbl as P
            tbl_src= table.current(1)
            tbl_dest = table.open("productimages")
            	tbl_dest.delete_range("Productimagename="+quote(name_ext))
            	tbl_dest.enter_begin()
            	tbl_dest.id = imageid.value
            	tbl_dest.Productimagename = name_ext
            	tbl_dest.Productimageindv = image_filename_encode(newfilename)
            	tbl_dest.enter_end(.T.)
            	tbl_dest.close()
            
            [COLOR="#FF0000"]dim tbl as P (This is parent table that is already open). 
            tbl_dest = table.current(1)
            	tbl_dest.enter_begin()
            	tbl_dest.Productimageindv = image_filename_encode(newfilename)
            	tbl_dest.enter_end(.T.)
            tbl_dest.close()[/COLOR]
            Here I am updating the child table. But I would like to update the main table one field. Is my code correct?

            Then I would be able to use the image field directly.

                  Hi Stan:

                  You are right. I am changing the record.

                  Here is the code i updated to:

                  Code:
                  tbl_src= table.current(1)
                  tbl_dest = table.open("productimages")
                  tbl_dest1 = table.open("merchandisedetails")
                  	tbl_dest.delete_range("Productimagename="+quote(name_ext))
                  	tbl_dest.enter_begin()
                  	tbl_dest.id = imageid.value
                  	tbl_dest.Productimagename = name_ext
                  	tbl_dest.Productimageindv = image_filename_encode(newfilename)
                  	tbl_dest.enter_end(.T.)
                  	tbl_dest.close()
                  	
                  	[COLOR="#FF0000"]tbl_dest1.change_begin()  [COLOR="#0000FF"]This only changes the 1st reocord. I need to match the id. [/COLOR]
                  	tbl_dest1.Pimage = image_filename_encode(newfilename)
                  	tbl_dest1.change_end(.T.)
                  	tbl_dest1.close()[/COLOR]
                  One major issue. The change is occuring only on the first record of parent.

                  How can I update the record matching the id?

                    Change this

                    tbl_dest1 = table.open("merchandisedetails")

                    to

                    tbl_dest1 = table.current(1)

                    and you will be changing whatever parent record is displayed.

                    Probably want a parentform.resynch() at the end to force the table fields to be refetched from the newly changed record.
                    There can be only one.

                      The following is in-fact the parent table. Also, it is the child of the another table.

                      tbl_dest1 = table.open("merchandisedetails")

                          this worked!!!!

                          	tbl_dest.enter_end(.T.)
                          	tbl_dest.close()
                          	
                          	tbl_dest1.change_begin() 
                          	tbl_dest1.Pimage = image_filename_encode(newfilename)
                          	tbl_dest1.change_end(.T.)

                          I just changed 1 to 2.

                          Thanks for help!
