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.

    Re: text to image file data

    I've dealt with some of the things you mention - file size reduction, cropping and zooming and combining text and images. In the latter I write the details of a ticket to the top of the image of the materials we have purchased. The script is only 30 or 40 lines but it took me some time to wrap my head around how to apply the various functions to get the desired result. And I hope not to have to do so again!

    In the FWIW department, I have repurposed the old EzTwain scanning ActiveX as my vehicle for cropping and zoomimg. It's very easy to build theXdialog to display the image and the it eliminates the need for all the complexities involved in the low level functions in Alpha. I'm so glad I bought my own Eztwain license years ago and that ActiveX continues to sail along in Windows 10.

    Re: text to image file data

    Hi Finian,
    Thanks for your thoughts. I played with the CHAR_TO_BLOB() a bit today and it holds some promise. Yet today I was confronted with the new request to be able to also capture assets from web pages that can be a mix of text and images. So I spent the day working the angle of screen prints to clipboard to blobs to image reduction scripts to openings in apps for cropping and file saving... I work though xdialogs, intricate dialogs, with scripting to present and modified images in the dialog, that supplies tremendous capabilities, and I am so, so close to getting to functionality to cover all the possibilities. If it wasn't a challenge it wouldn't be fun, right?

    I should have said Win7 Mike.
    I'll try Win10.

    Mike:

    Have you looked at the CHAR_TO_BLOB() function at all? I think you could use it and/or the UI_BITMAP_CREATE(), UI_BITMAP_DRAW() and FILE.TO_BLOB() functions to do what you want, unless I musunderstand what it is you're trying to do.

    Well Ted,
    You must have that very, very special version of Paint, or maybe copying text data to the Clipboard on your side of the pond works differently, but trying this in both XP version and Win 10 version of Paint brings no joy. Thanks for your efforts. I think I'll be going with users opening the text, performing a Print Screen, and processing that image data for the thumbnail from the clipboard data. I think it might be a workable alternative.

    Maybe I misunderstood Mike, but in my version of Paint, I can paste directly from the Clipboard into a new instance of Paint.
    I tested this using some script in a Word document, copy and paste and save as.Mike Wilson Image.bmp
    If you cannot get at the text, then that is more of a problem I must admit.

    I've not used macros for a while, but seem to remember that they can be pretty useful.

    Hi Ted,
    If text data written to the clipboard could be pasted into Paint, yes, this could be a strategy, however, this isn't possible. I am wanting to not have to re-type the text into an image application then to be saved as an image file.

    Re: text to image file data

    The only way I could find would be by running a Macro to launch paint and save the text as a bmp.
    Perhaps this coud be run outside AS

    Re: text to image file data

    Hi Robin,
    The form for the asset table has 15 bitmap objects (see image). The button in the embedded browse "show" calls a script that changes the file name for each of the BMP objects display for the 15 sequential records. Yes I could overlay a second text object over the BMP object and have them both within conditional objects, but I rather not have to do all that. If there was a method to convert text to binary image file data, that would be much easier. The images presented are small, thumbnail files depicting the master high resolution library files. The button above each BMP object opens the master high resolution file.

    Re: text to image file data

    Are the file extensions either BMP or TXT? If so couldn't you use a conditonal object on the form to test the type of file you need to display?

    text to image file data

    We have a repository of data used as a library for assets for marketing materials. The majority are image files. I have a form with a BMP object that shows the file contents. When the file contents holds data that is in BMP format, all is good. What I need is to be able to show the file content when the data is a text file. Is there a method using xbasic code to convert data in a text file to bmp format data so the data in a text file can be viewed in a bmp object?
