you have to read the original file, create a new one, and write inside it what you copied from 1st file....

the functions you can use are fopen(), fread(), fscanf(), fwrite(), fprintf(), fclose()...

also, see fstream if you have any chance to code in C++...

hey, you asked from the C-runtime, not Win32 API Unsure | :~

if so, then NO, there's no "copyFile"-like function in the C runtime.

then, what's your need exactly ?

just make a copy of the file
then use CopyFile() from winAPI

Automatically run application after installation

I was wandering if someone could help me to solve this problem:

I created a C++ win32 application and I need to distribute it over a network,

I made an installer for it and I have my MSI package, at this point everything is ok, because I can deploy my app over the network and, using an unmanaged installation, I have my app installed and I have written in the Windows registry so that the app starts after login...

But then to run the app I need to reboot all the computers...

Does anyone know a way to automatically run my application after install?

I cannot made it work... I find many suggestions, no one worked, but I think it schould not be difficult, I just don't find it or I do not understand how to do it!

Thank you for your help and excuse me for my poor english.

Nicola.

You can use
WinExec( LPCSTR lpCmdLine, // command line
UINT uCmdShow ); // window style

to run your application.

Ok, but where should I put this piece of code?

Should I build a DLL, and than run from a Custom Action in the Installer?
How do I pass dynamic parameters as the path of the app that I know only during installation?

I read about VBScripts that I can launch as Custom Action but I don't understand how to pass parameters.

Thank you for your help,

Nicola.

It is not possible to make an item Disable. How do u except the disable item to behave? By disabling u mean that item should not get selected by mouse or keyboard ?

I want to write an equation solver, Like Microsoft Student Graphing Calculator(Equation Solving tab).
I wanna solve equations like this :

Can anybody give me some sample code, or any suggestion
Thank you

Hum, that's not an easy task. You'll need to parse the string first. A parser example can be found in this[^] article.

IMHO, you would have to parse the string and put the elements on to a stack.
I did this sometime back so can't remember exactly but this is the logic that I used.

If you get an operand pop one element from the stack .
If you get an operator pop two elements from the stack , perform the operation and again put the result on the stack . Go on doing the same operation until the stack is empty

Somethings seem HARD to do, until we know how to do them.

1. I can't understand the meanning of the parameters in function DrawIndexPrimitive & DrawIndexPrimitiveUp &SetIndices. Could someone Illustrate me witch some very clearly example.
2. I dont understand format of texture with format DXTn.
I always get error when i try to access directly to it data.
For example:
For(y = 0; y < Height; y++){
memcpy((char *) lockedrect.pBit + y* lockecrect.pPitch,
mydata,
Width * sizeinbyteofpixel)
}
I dont known sizeinbyteofpixel is, i try with 1 and get error.
Someone tell me how i compute sizeinbyteofpixel.
And tell me why i alway get error.
Because i don't understand format of compressed texture.
I'm very thanks if some one tell me some good DirectX book to download ( free, i'm not have credit card to buy).
Or I'm very happy if someone share me with your favorite book
Thanks
