Display picture in a form

cn2607

I want to show picture in the picture box on a form. However, BMP file is stored at c:\pictures\xxxx.bmp. It is easy to show picture from a BLOB field of a table but how to show it by exporting from the above path. I tried with bitmaplist property but get an error "Invalid Device-independent Bitmap file"
Is it doable and if so how. Thanks for your input

Create C/AL global - type BLOB, make it a source exp for picture box and use IMPORT to import picture.

C&P from OnLine Help:
****************************************************
b.IMPORT
Use this function to import a BLOB (Binary Large Object).

[ImportName :=] := BLOB.IMPORT([Name [, CommonDialog]])
ImportName

Data type: filename

The name and path of the file the system imported.

If ImportName is...
It means the BLOB was...

The file's name and path Imported
Blank Not imported

BLOB

Data type: variable

The BLOB you want to import.

Name

Data type: text or code

The path and name of the BLOB you want to import. When you enter the path, keep in mind these shortcuts:

You can...
If the command is located...

Omit the drive designation On the current drive
Omit the full path In the current directory
Enter only the subdirectory name In a subdirectory of the current directory

CommonDialog

Data type: boolean

This tells the system whether or not you want it to display a dialog before it imports the BLOB. This dialog window lets you select the file you want to import. Based on the SubType property, the system only lists the appropriate file type, such as bitmap files (*.bmp), memo files (*.txt), or all files (*.*).

If CommonDialog is...
It means the system will...

TRUE Display the confirmation dialog
FALSE (default) Not display the confirmation dialog

Thank you, bostjanl.
From your response, I understand that ImportName is the name of the imported picture which then is used as a SourceExpr in the picture box's property.
However, when I tried to create a variable BLOB in C/AL, (been thru the help on the b.import function) I keep getting errors and seem to be missing something. Can you please expand on the definitions of eg ImportName supposed to be of type: filename, but is defined where?
BLOB of data type: variable - again defined where. I am not able to do it in C/AL.
I guess what I am asking is where do I assign the filename of the picture (C:\picture\xxxx.bmp) and will the adding of the import code in "OnActivate()" of the form will then work. Perhaps a code example will help. Thanks.

Hi!

Ok, here it is:

1. Define C/AL global temporary record, which has BLOB field,.. Let say "Company Information".
Picture 1

2. Add picture box to form ans set its SorurceExpression to Picture field in temporary record
Picture 2

3. Add push butttom with code
Picture 3

4. run the form
Picture 4

5. Push te button
Picture 5

Thank you, bostjan. Works like a charm. It's the temporary 'record' type variable which uses 'picture' field from table company info.. etc and this is what I was missing.
Many thanks again for an extremely descriptive explanation of the whole process.
