Hello,
Thanks a lot for reply. I attached the source code below:
If i click the submit button the following code is executing.
--------------------------------------------------------------
FILE *fleCredentials;
try {
// Create a new file or open the existing one
fleCredentials = fopen("credentials.crd", "a+");
{
// Add the username to the file
//
fprintf(fleCredentials, "%s ", (LPCTSTR)m_Username);
// Add the password to the file
fprintf(fleCredentials, "%s\n", (LPCTSTR)m_Password);
}
// After using it, close the file
fclose(fleCredentials);
--------------------------------------------------------
|
|
|
|
|
What is the data type of m_Username and m_Password?
|
|
|
|
|
m_username and m_password are CString types.
|
|
|
|
|
If you use the debugger at that function to save the two files, I bet you get...
m_User = "user" and m_Pass = "pass" (I can't see your original code)
And then your text file will be....
userpass
with no way of know where one starts, and the other finishes...
Instead of CString, try using a fixed character array, and then saving that out. It will be much easier when you load it. It will have the restriction of only being able to have user names and passwords of a certain length, so don't make it too short!
Iain.

Try using GetBuffer() function for the CString objects in the fprintf statement?
|
|
|
|
|
No, don't do that at all.  The GetBuffer() method should only be used when write access to the internal buffer is required. In this case, it is not. The LPCTSTR operator is all that's needed.

How are you verifying that only two characters (one from each variable) exist in the file? Is this a Unicode application?

How to edit subitems in a list view , i tried LVS_EDITLABELS but it allows to edit first column only.
Thanks & Regards

Have you tried SetItemText?
|
|
|
|
|
There is not provision in list control for doing this. U have to create your own edit control and manage it. You can find many samples in code project itself. Search.....

i have a combo box which contains interger values and i have couple of files in my application. i have mapped this combo box to integer. i am getting the index of the value and i am using cstring to convert it to the original value. for ex. there are 2 values in my combo box. 100 and 200. if i select 100 i get the index as 0. and the CString variable will return the value(100). now my requirement is i need to pass the value(100) to another file. how do i do it?

You can write get/set function and then using class pointer access those values in another file.
Somethings seem HARD to do, until we know how to do them.

is there any other way other than that?
|
|
|
|
|
If your classes support parent/child relationship then you can use GetParent() from your child class to access the members of the parent.
(P.S. - Is there some problem in getting the values as per my previous suggestion.)

there is no problem in doing so. but thought the other way where u make an instance of a class and pass the value thru that.
|
|
|
|
|
as a constructor parameter for instance...

Hi Experts,
How can I enumerate of all Bits of a Byte variable.
Thanx in advance.
|
|
|
|
|
try this
byte byValue = 12;<br />
byte byExtractor = 128;
for( int nIdx =0; nIdx < 8; nIdx ++ )<br />
{<br />
byte byBit = (byExtractor == (byValue&byExtractor));<br />
byExtractor = byExtractor>>1;<br />
std::cout<< "bit at "<<nIdx<<"th position is "<< byBit; <br />
}
|
|
|
|
|
|
Did you mean something like this? 
BYTE b = ???;
for( int i = 0; i < 8; i++ )
{
cout << (( b >> i ) & 0x1 ) << endl;
}
