hi,

I want to get the width and height from the user through the edit control and storing it in the RECT structure but it's getting the only one value at a time and strucking,can you tell me what is the problem here???

CRect reect; (I want to store height and width here)
CString s,s2;
m_height.GetWindowText(s); //m_height is the edit control
s=reect.Height();
m_width.GetWindowText(s2);
s2=reect.Width();
GetClientRect(&reect);
m_shockwave.FOPSetClientRect(reect);

You need to reword your question to make others understand. I'm sure, you have not tested this code. Its very difficult to understand your problem, seeing this descriptioni.

What you are trying to say.Without testing how can I blindly post it here.

I want to get height and width that is two parameters from the user ,and I want to set it in a RECT structure(I think here it's clear).

From your original code, watch the line in bold

CRect reect; (I want to store height and width here)
CString s,s2;
m_height.GetWindowText(s); //m_height is the edit control 
s=reect.Height();  //This will not compile
m_width.GetWindowText(s2);
s2=reect.Width(); // This will not compile
GetClientRect(&reect);

For this you can use DDx to associated edit controls with integer variables and assing it to RECT.

When IE is configured to use "automatic configuration script" -- is there any easy way to programatically figure out the type and location of the proxy in use?

Do I need to execute the script myself?

PCI Parallel Port

I wanted to program my parallel port, but unfortunately it is on a PCI card and has a base address of E800. I am also running XP so there doesn't seem to be any easy way of just changing my port settings. I wanted to know how to send data to my PCI parallel port. If anyone could help me out it would be greatly appreciated. Thank you. Blush | :O

I might be off track here, but I think you need to look at this http://www.codeproject.com/script/comments/forums.asp?msg=1937167&forumid=1647#xx1937167xx[^]

which is from a few threads below this. The dll that he's using allows lower level access, I 'think' you can access a parallel port though it as well ..

(else do a google for inpout32.dll and see if it helps, thats what this bloke was using)

are you able to transfer single character at a time... if yes.. then it pretty much easy.. create some header mechanism or handshaking .. i.e.
communication between two port,
Port5 : connect to Port 6 com port!
Port5: File K0 (0x03) //end character
port6: File 10 codeproject.cpp (0x03)
port5: Data K0 (0x03)
port6: Data 20 12345678901234567890 (0x03)
loop back till you recv whole file!
here File and Data are Command and
File K0 asking for file name and in return it's getting File [Length of FileName] [Actual FileName]
Data KO format will be Data [Length of Data] [actuaLData]

Hi all ,

I have done ping coding in thread. That thread is made in a class and that class is derived from CWinThread (its a user Interface thread). I have made a list control in my applcation and i can select various no of rows to ping at same moment.This all is working fine.My problem is in displaying the result in list control. I have used SendMessage function for that.But the result displayed is same for all rows.

I have tried using PostMessage but then also same problem is there.Can anybody solve my problem.

Thanks in advance...

The problem is with selecting multiple rows. When u r selecting multiple rows only the last one is getting reflected. Try to track the row numbers and also send them using PostMessage.

3. Write a program which outputs frequency of digits in a given integer. For example, if the number is 12424329, output will be
Number Frequency
1 (space) 1
2 (space) 3
3 (space) 1
4 (space) 2
9 (space) 1

Use a switch statement to obtain frequency of the digits.

This means nothing (space) i just put in so the numbers would line up

HomeWork/Assignment?
The solution to your problem is pretty simple. 10-15 lines of code would produce the desired result.So rather than giving the solution here's the logic that you can build over:
1. Ask the user to input a integer.
2. Now you need to check if the integer at 0th index is repeated elsewhere in the number and so on.
3. If the number is repeated increment the count by 1

If you are having problems on how to get the individual numbers from 0-9 out of the number entered here's the logic for that too-
while(temp!=0){
n=temp%10; // temp is the number entered by the user
temp=temp/10;
//// Do something
// Increment count and print it
}

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

Creating a Control from a resource

StevenS_Dev12-Mar-07 15:17

12-Mar-07 15:17

I am curious how to create a Control from a resource ID using Create. The MSDN documentation states: "You can create an edit control either from a dialog template or directly in your code." I guess my question is whether this is possible from Create? What do you pass for styles and rect?

I am more familiar with using GetDlgItem or using DDX/DDV.

I am asking because I am converting old Borland OWL code to MFC. OWL has two constructors for controls. One version creates a dynamic control, similar to Create. The othter constructor takes a parent window and a resource ID. As there is no equivalent in MFC, I am wondering if I can use Create, or if I should suggest scrapping the conversion of these particular classes and just use the more familiar way of doing this.

Thanks for any input.

Yes it is, first parameter of Create are style to be given for particular component. Same function has parameter to decide its parent.

I hope I understood your question.

See MSDN for ::CreateWindow()

hWndParent
[in] Handle to the parent or owner window of the window being created. To create a child window or an owned window, supply a valid window handle. This parameter is optional for pop-up windows.

hMenu
[in] Handle to a menu, or specifies a child-window identifier, depending on the window style. For an overlapped or pop-up window, hMenu identifies the menu to be used with the window; it can be NULL if the class menu is to be used. For a child window, hMenu specifies the child-window identifier, an integer value used by a dialog box control to notify its parent about events. The application determines the child-window identifier; it must be unique for all child windows with the same parent window.
