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.

  • image file from clipboard data

    Code:
    	dim cc as C
    	dim bb as B
    	cc = clipboard.Get_Data(8)	
    	bb = char_to_blob(cc)	
    	file.From_blob(vyg_lbl_folder+"import.bmp",bb)
    From MS Paint I cut an image (to clipboard). I'm trying to get that clipboard data to an image file. I've been through the docs and the MB looking and trying various things and I just can't get it. Neither cc as C or B works. The "*" parameter is because the docs list this as bitmap data. No joy. Can anyone point me in the right direction please. Much appreciated.

    Re: fimage file from clipboard data

    Years ago I did something similar however I used files. My script would open microsoft excel, copy a range of cells from a workbook page to the clipboard, paste the clipboard into paint, save the paint as a file and then enter the file into a field in a table.

    I found this in the help files. It worked perfectly. This may be a viable option.

    <FIELD>.MEMO_READ_FROM_FILE()
    Syntax
    <FIELD>.MEMO_READ_FROM_FILE( Filename as C [, Flag as N ] )
    <TABLE>.<FIELD>.MEMO_READ_FROM_FILE( Filename as C [, Flag as N ] )
    Argument
    Description

    Filename
    A fully qualified file name.

    Flag
    Optional.

    Default = "" (Overwrite memo).

    MEMO_APPEND = Appends Filename to the existing memo, rather than overwriting it.


    Description

    The <FIELD>.MEMO_READ_FROM_FILE() method transfers the contents of a file to the memo or bitmap field referenced by the <FIELD> object pointer.

    This function is especially useful for putting Windows Bitmap files (.BMP) into bitmap image fields.

    Flag is an optional parameter that you can specify in the case of memo fields (not bitmap fields) to append the contents of the file to the existing memo, rather than overwriting it.

    Supported By Alpha Five Version 5 and Above

    Example
    This script inserts the selected bitmap file into the Picture field in a new record in the Library table.

    dim tbl as P
    filename = ui_get_file("Choose Bitmap", "Bitmaps(*.BMP)","","X")
    if (filename = "") then
    end
    end if

    tbl = table.current()
    tbl.enter_begin()
    tbl.description = filename
    tbl.picture.memo_read_from_file(filename)
    tbl.enter_end(.T.)
    parent.resynch()

      Re: fimage file from clipboard data

      Ron, good to know about that method, but I am starting from cutting image data to the clipboard, wanting that data on the clipboard to get into an image file using xbasic.

        Re: fimage file from clipboard data

        Look at the Clipboard actions you can use. The clipboard contains whatever you have copied.

        Description

        The CLIPBOARD.GET_DATA() method gets data from the clipboard and stores it in Variable. The type of data retrieved from the clipboard is determined by Clipboard_Format. You can register a new Clipboard_Format value with the CLIPBOARD.REGISTER_TYPE() method.

        Supported By

        Alpha Five Version 5 and Above

        Limitations

        Desktop applications only.

        Example

        This script puts the record into change mode and writes data from the clipboard into the account_number field.

        tbl = table.current()

        tbl.change_begin()

        tbl.account_number = :clipboard.get_data()

        tbl.change_end(.T.)

          Re: fimage file from clipboard data

          John, I seem to recall trying to do this myself back in December 2011. For some reason I do not think I could get this to work. Hence, I took the file method. I do have a post dated 1-18-12 called "file.to_blob code works in Windows XP, doesn't work in Windows 7".

          I posted a test sample that you may want to down load and try. I don't remember all the details.

            Re: fimage file from clipboard data

            I came upon this thread, and since I had been part of the one Ron referenced without providing any help there, I thought I better do better. I found this great intermediary function that allows the clipboard data to be previewed, adjusted, and then capable of being made into a bmp or jpg file. Heck I've got lot's of uses for this!! Into the code library with this one!

            Steps: Cut an image to the clipboard and run this script

            Code:
            'set the file to be made from the clipboard image data
            	dim vf_new as C="C:\text_clip.jpg"
            	
            'acquire the image data from the clipboard, 
            	dim vblb as b
            	vblb=clipboard.Get_Data(8)
            	b2 = a5_image_transform(vblb)            ' <<<--- fun new function I found
            	
            'convert to jpg file
            	dim vjpg as B
            	vjpg = bitmap_to_jpeg(b2)
            	file.From_blob(vf_new,vjpg)
            
            'Query user to preview new jpg image file
            	dim vnR as N
            	vnR=ui_msg_box("PREVIEW IMAGE FILE","Preview the new image file now?",65)
            		if vnR=2
            			end
            		end if
            
            'load the selected image and view in dialog  
            	dim inow as C
            	dim rgb_data as B
            	f = file.open(vf_new,FILE_RO_SHARED)
            	ui_bitmap_load("inow",f.readb(10000000))
            	f.close()
            
            	ui_dlg_box("Image Preview",<<%dlg%
            	{lf};
            	{image=inow};
            	{lf};
            	<OK>;
            	%dlg%)
