Hi All, what is the way to pre-load a bitmapviewer at program-startup with an image without loading it from file? I use VB6. With a picturebox, you can simply at design-time load an image file, which will thereafter be included in your program. Can that be done with Aurigma? Thanks, Kees

Hi Kees, Unfortunately it cannot be done in design-time. So the only way to pre-load an image at program startup is to call LoadFromFile in Form_Load.

Thanks. Might there be a way by using a VB6 picturebox as a picture store, and then copying the picture to a bitmapviewer in Form_load()? For example, by setting a pointer to the picturebox.picture and use CopyMemory to transfer it to the bitmapviewer? It is kind of important because I am distributing a lot of copies of my software to students, and I want to present them with as fool-proof as possible startup. Thanks, Kees

You can do it in the following way:
Code:
BitmapViewer1.Bitmap.Data.Picture = Picture1.Picture
BitmapViewer1.Bitmap.Data.ConvertTo24bppRgb
However I did not quite understand why you need it - do you have your students to modify the source code of your application?

Thanks, Andrew. No, the students do not modify the source. I have made a program for scientific image analysis that is based on Aurigma. The idea is to collect three different microscopic images of a cluster of cells labeled with 2 different colors. I collect pictures: 1) illuminate with blue, detect 'blue' with a monochrome CCD camera with blue filter 2) illuminate green, detect 'green' 3) illuminate blue, but detect in green (i.e., this is a spectral 'bleed-through' image) The colors show a very interesting property (called FRET) that allows us to directly calculate molecular interactions because they change the amount of bleedthrough. So my program calculates molecular interactions from a set of 3 images. Quite different from your usual applications, not? I'll be happy to tell you more, but perhaps of this forum because I have not seen other guys use Aurigma for scientific calculations. best regards, Kees

Oh, and the reason why I need to include the pictures is this. Biology students are so amazingly stupid that no matter how many errors you catch, they will crash my program. So for the absolute morons between them for who even 'load 3 different images' is too difficult, I want to preload the images. This cannot be done with 'loadfromfile' because even those files, they manage to delete. I figured: one .exe file that contains absolutely everything they need is the only way to make it fool-proof.

Andrew, still something seems to go wrong with the solution you suggested. If I clone the picture that was just generated by your two lines, I get an unexpected error and am asked to contact Aurigma:
Code:
Private Sub cmdtest_Click()
    'get pic from picturebox
    bmvLut.Bitmap.Data.Picture = formPicStore.picGrayLut.Picture
    bmvLut.Bitmap.Data.ConvertTo24bppRgb
    set bmvStampLUT.Bitmap = bmvLut.Bitmap.Clone  <<-- error
End Sub
any ideas? Kees

In fact you can store images as byte arrays and load the image using LoadFromMemory method.

Do you get this exception if you clone the image loaded from file (i.e. use LoadFromFile instead of bmvLut.Bitmap.Data.Picture = formPicStore.picGrayLut.Picture)?

No I only get this error if I clone it from the picturebox in the way I described. Cloning from Loadfromfile routinely goes fine. Best regards, Kees (sorry for the delay in answering. I was abroad)

Ok, I have told developers to check this problem out. Meanwhile, try the following workaround: right after clone select output image format:
Code:
bmvLut.Bitmap.Formats.SelectCurrent "BMP"
