On win2k and earlier you can use the Wang/Kodak imaging controls (image edit, image admin, etc), on xp and later you can use WIA (Window Image Acquisition). Search MS for the SDK download...

Good Luck

how to open .cal or .tiff extension image files from vb6.i dint get solution.
for exaple we can open image binary text from bmp or gif by type declarations lik BMPHEADERINFO and BMPFILEINFO.
Type BITMAPFILEHEADER
bfType As Integer
bfsize As Long
bfReserved1 As Integer
bfReserved2 As Integer
bfoffbits As Long
End Type

In this way, can you say me how to read image text like height,width,size,bitcount of .cal and .tiff extension image file.if there is no solution lik above user define type declaration.
then how can i get image header text information of tiff or gif.and i want code????

First, you have created this thread as a code snippet asking how to do something. Second, I gave you the leads you need to solve your problem, and now third you are demanding code??? Well, I don't think so. You want code, see the WIA 2.0 SDK that you can download from MS or use your friends (yahoo, google, ask, answers, bing).

Look at this search of MS's web site....

http://search.microsoft.com/results.aspx?form=MSHOME&mkt=en-US&setlang=en-US&q=WIA+SDK

See the second one down? When you click on that go to the bottom and go after v2.0 if you need to. The SDK has examples and if you look further down, you will see a tutorial page for WIA.

Use your friends (yahoo, google, ask, answers, bing) and search the web for vb6 wia sample as I did here...

As for vb5progrmr instructions, i wouldn't waste my time with it either. If he cannot provide you with the code then go to another forum where people are a little bit more forthcoming. I would like to help but as far as I know, you cannot determine an extension that is not part of the VB6 picture extension formats. I think they are - *.bmp, *.gif, *.jpg.

You need to be able to read the properties of the image as you will not be able to load then determine the properties.

You need to be able to access the properties of the file and figure out how to read the dimensions.

J2, read the forum rules...

AND, if the OP would download the WIA SDK they would have all the example code they would need. It is that simple!

By the way, Classic VB or Visual Basic 6.0 has the ability to display BMP, ICO, GIF, JPG, JPEG, EMF, WMF. Then with win95 to win2k the Wang/Kodak controls allowed us to display Tiff files among other formats, and after that, MS invented WIA so various formats could be displayed including Tiff. Then with the use of WIA or GDI+ PNG's can be displayed...

As for giving away code J2, I am not in business or in the habit of doing such a thing as I am paid to create code, so why would I just give it away???
