I assume those that did not work were conversion files and not true .BMP files. In any case, I have a graphic that has a transparent background. This is less of a problem than what I was trying. To advance to the next step, I tried to get it act as a command control without success. I tried placing it on an Image Control and tried using it alone on the form - neither worked. My Click sub did nothing. Can you help? Thank you, Jim >

Is there a specific model (?) number that I should seek? I don't want to pay $114.00 if I can get the correct version for $29.95. Thank you, Jim Y

If you mean that literally, as in you would consider yourself fortunate to have such code written in *ClassicVB*, I have some I'd be happy to share. -- Working without a .NET? http://classicvb.org/

I never really got into using a resource file. When I did play with it, just to see how it worked, I had to write the file out in notepad and use RC.exe from the (VB5) CD. While they do provide a load-on-demand advantage, I didn't like their hidden nature. I couldn't go somewhere to see details (images or names) and adding more resources was also a bit long winded, (back to Notepad, recompile, re-link, etc.). If, as often happend, a small change was needed in an image, it was too long a process to effect the change. Stuffing images into a form was far more versatile, and easier to manage. I rarely used so much image data that leaving it all loaded was problem.... LFS |
