Have a look in the registry

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

There all uninstallable programs are registered.

Some notes on the keys which can be found there:
- "DisplayName" is the displayed name in the listbox.
- "UninstallString" tells you which command is executed when the user clicks the "Add/Remove" button in the control panel.

Hi.

I would like to change the initial location of a dialog box (modal and/or modeless.

For example, in the program I can current working on, Windows paints the the modal dialog box in th center of the program. I have to move the dialog box to the size to see the main window. I would like to change the initial location of a dialog box.

Thanks,
Kuphryn

Use the MoveWindow API call

OnInitDialog() is called before the dialog is actually shown. In this function, use either SetWindowPos() or MoveWindow() to change the window position. In this way, when it is shown it will appear initially in the correct place.

I would strongly suggest that if this is a commonly used dialog you save and restore the window position; this way users can put it whereever they want it, and it will appear there initially from then on.

MoveWindow(...) works great.

Now I just need to save the position in the registry.

Sure. Shog9 implied that the dialog box should at the last position before the user closes it. The only way to do that is to save its last position int he registry.

I want to read from file ,line be line and after reading each line modify it and write modify string to file.I use this code:]

CStdioFile inFile;
					
inFile.Open(strpath , CFile::modeReadWrite | CFile::typeBinary);
char buf[80];

while(inFile.ReadString(buf,5))
{   
CString outdatastring;
for (int i =0 ;i < 5; i++)
{
//Do some modifing
//
}
				
inFile.WriteString(outdatastring);//outstring is modifeid CString
}               
inFile.Close();

But I got this error after in run time:

Disk full while accessing F:\Doc\Change List - Beta2 to RTM.doc.

Any suggestion?

First question: you use CStdioFile, why do you open the file with the CFile::typeBinary parameter?????? Normally CStdioFiles are opened with CFile::typeText! If you need to read binary data you should use the normal CFile class. My suggestion: change CFile::typeBinary to CFile::typeText.

Second question: why is the char buf[80] 80 chars long and you use only 5 chars of it? My suggestion: read the COMPLETE string (can be much longer than 80 chars, so extend the size of buf) and then process only the first 5 chars. Thats much better. I don't know how ReadString reacts when it doesn't reach the end-of-line character and then is called again.

I"m not sure about this, but

BOOL m_bFirstPass;

CDialog:CDialog()
{
  m_bFirstPass = FALSE;
}

CDialog::OnInitDialog()
{
  m_bFirstPass = TRUE;
}
 
CDialog::OnActivate()
{
  if(m_bFirstPass == TRUE)
    //Execute code only on first call
    m_bFirstPass = FALSE;  //Prevent from code being    executed again
}

This might work! Smile | :)

Adding Message Handler in MFC with Visual C++ 7.0

6-Apr-02 2:29

Hi
We have a problem adding message handling functions for Non Dialog Controls in MFC with Visual C++ 7.0.
We cant find a way to do this the easy way. The Class Wizard which existed under 6.0 doesn't exist here, and thru the events in the properties of a class only menu and accelarator IDs are accessible. None of the Buttons from a Toolbar for example is available.

Thanks
Lars

Well, first of all, in most cases where you have toolbar buttons, you should also have a corresponding menu item, or at least an accelerator. In these cases, the Events property sheet will work. If you absolutely cannot have a menu or accelerator for your button, it is trivial to add the message map entry manually:

ON_COMMAND(Command ID of button, Handler function)

trapping GDI objects

Is there any way GDi objects can be trapped,ie Images of the application.At the operating system level,Probably Input output request packet(irp) form the gdi objects,but that would involve hooking the kernel....

Thanks for spending time...

You can try API Capture. Someone just posted an article on this topic. With this technique you could trap all of the GDI calls from a particular app, change the calls, or just spy on them, it up to you.

TCI/IP in C#

I know this is the C++ forum, however it was the suggestion of another to post this question here. Suppose someone were writing a "firewall" application that was "watching" or listening for activity over an incoming IP address, what is the best way to cover all ports. In all the examples I have read, someone creates an instance of TcpListener and supplies a port to listen to. Surely you don't have to do that for each of the 65,000+ ports. Could someone lead me in the right direction. I am going to do this in C#, Thanks in advance. Confused | :confused:

Problem with htonl() function!!!

5-Apr-02 23:53

Hi,

I use the htonl() fonction to convert an IP address from "host byte order" to "network byte order" but it does not work, or sometimes it work and sometimes not!!!.
here is the portion of code that i used to display the IP address :

in_addr addr;ip = htonl(ip);// ip is an u_long already initialized
addr.S_un.S_addr = ip;char* dst = inet_ntoa(addr);AfxMessageBox(dst);

what is going wrong ?

The snipit of program below should create a table 25*25 with the alphabet in each row(in theory i think.
Dose any body know how i can use that table? i basically want to compare a word entered with that table. But cant seem to do this.
Any code will be very helpful

void CFinal3Dlg::OnBeta()
{
radio_select=2;
//create table
for (row= 0; row<=25; row++)
{
ch='A'+row;
for (col=0; col<=25 ; col++)
{
ch++;
if (ch>'z') ch = 'A';
}
}
// compare entered data with table
{
