see i will tell u, there are many CStatic objects on the client window, right. Now what happens is that the user clicks on one of them and i get the address of that object in the 'this' pointer. Now i want to move this object according to the mouse drag on the screen, with the help of SetWindow Pos func and Invalidate(TRUE); I have the address of the CStatic object which the user is trying to drag.How do i get the handle of this object so that i can move it. is there any way to find out the handle with the help of this pointer.
otherwise tell me how i can move the CStatic window along with the mouse.

tab control

Hi all,

I'm writing an application to model the effects of
different volcanic sources. For every source i put in a dialog box
a combo box to select the kind of source and all the control to set the parameters
of every kind of source. Selecting the kind of source in the combo box only
the meaningful controls for that kind of source are enabled.

Acting like that my dialog box takes too much space on the screen,
so i need to split the different kinds of source in a tab control.
Can i do that without rewriting too much code ?
Is there a way to know which tab is selected ?
Sorry for the question but i'm a newbie.

Thanx in advance,
Demsmo16.

Hi,

You should think about using CPropertyPage and CPropertySheets. Converting from existing dialog resources is quite simple, and theres a good article regarding this on MSDN called Converting Large Dialogs into Property Sheets. Just search for that in Yahoo and you will find the article.

Good Luck Smile | :)

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 ?

Re: C run-time file copy routine

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 ?
