One way would be to implement the ISerializable interface and take these things into account yourself. Another way - especially if your assemblies are versioned (or better yet, strongly named) - is to extend the SerializationBinder and override BindToType so that when an older Type (since a Type name includes not only the fully-qualified class name but also the assembly information) you bind it to your new Type. You'd still have to take into account any changes, but this is a common and pretty efficient way of solving the problem of versioning. See the documentation for the SerializationBinder method in the .NET Framework SDK for more information and an example. Microsoft MVP, Visual C# My Articles

ColorPalette is a value-type. You can change a value of it when it's a property of another type. For more information about value types vs. reference types, see http://www.albahari.com/value%20vs%20reference%20types.html[^]. In order to change the palette, you must first get a copy of the ColorPalette struct: ColorPalette palette = img.Palette; palette.Entries[0] = Color.Red; img.Palette = palette; Microsoft MVP, Visual C# My Articles

Sorry if I was a bit offensive. Your solution works, but not in my particular case, because it is quite likely that the palette contains several identical colors, and there should be used as different color by the software.

After many testing, I've discovered that it didn't work because of my Office XP. I have installed Office 2000 instead, and now it works. Except for one thing. I'd like to replace text which is a TextBox, and not in the body of the document. But Word.Content doesn't include shapes apparently. Anyone with an idea?

Hi, did you solve the problem with _GetBaseMessageMap in VC7? I ran into the same.

Look at my Bzlib managed wrapper article right here on CP! leppie::AllocCPArticle("Zee blog"); Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

I've made some further testing, and discovered it comes from the format. With two similar picture, 256 colors,one is png the other is gif Bitmap bitmap = new Bitmap("Myfile.png"); -> bitmap.PixelFormat = PixelFormat.Format32bppArgb Bitmap bitmap = new Bitmap("Myfile.gif"); -> bitmap.PixelFormat = PixelFormat.Format8bppIndexed Conclusion : The png codec is "buggy" and if you use the standard constructor, the bitmap ignore the file attributes and is always 32bppp. The gif coded works OK, and the bitmap keeps the file attributes. With this, I've reduced my application memory usage by 60%

glad to here you fixed it! "When the only tool you have is a hammer, a sore thumb you will have."

The actual name of classes were just illustration, ht class architecture is muh more complex. I'll try what you say. It was what I read in the documentation, but I was doubtfull it would actually save an array of derived classes as the shapes member in my CDrawing class.
