How to read Bitmap file using BITMAPFILEHEADER structure. Can any one give some guideline regarding this ?

All the info you need to parse and load a BMP file is linked to in the
BITMAPFILEHEADER documentation. Here's the link:

Bitmap Storage[^]

There's all kinds of examples around, probably many here on Code Project Dot Com.

i used that BITMAPFILEHEADER structure, but bfType variable in that structure is not giving proper value, i.e it is giving 0 instead of "BM".please further give some more solution in this.

If you can't get the correct values for the BITMAPINFOHEADER structure (the 'BM' signature), then the resource you're trying to edit is probably not a bitmap or it is compressed.

Then the structure isn't valid or you're doing something wrong.

You'll need to post the code you're using to read the header structure(s).

Design Patterns are solutions to common programming problems and the term "Design Pattern" is used to describe various common solutions. A good C coded book is Design Patterns: Elements of Reusable Object-Oriented Software[^].

Also, I'm currently writing some articles about design patterns and providing some good practical examples, however, these are in C# (you won't have problems understanding C# syntax if you're familiar with C and C++).

My first is about Implementing the State Design Pattern[^]. I will be writing a lot more of these.

Hope you can visit and please feel free to comment or ask questions.

Strange behaviour with Registry value

Hi all,
I am working on password protection for my application,
for which I am using just a simple XOR encryption.

The value written in Registry is different from what I read.
If the CString contains the values, 0xF2,0xF4,0xEF,0xE8,0xED

the read values are, 0xF2,0xF4,0xEF,0xE8,0x3F
The last value read is wrong.
This is happening on Korean Systems.Working fine on a system having english OS.What might be the problem.
Please tell me how can I overcome the problem.

Regards,
Sunil Kumar

At first you better use a stronger encryption.

The string problem may occure because of conversion of the last byte. You better use Registrytyp BYTE.

Do you want to send the exe as an attachment with an e-mail?
Do remember that some servers may restrict sending/receiving of exe's
Did you see MAPI?

You need to google first, if you have "It's urgent please" mentioned in your question.
