Hi All,
In my project I want to get the string value set in text box. So I write
following code as
CEdit *pOpenEdit = (CEdit *) GetDlgItem(IDC_FOLDER_PATH);
if( NULL != pOpenEdit->GetSafeHwnd())
{
pOpenEdit->GetWindowText(buff,256);
}
In the above code I did not get handle of edit box. What is wrong in this code.
Please send me solution if anybody have.
Thanks
Om

What happens if you run this code?
CWnd *pwnd=GetDlgItem(IDC_FOLDER_PATH);
pwnd->GetWindowText(buff,256);
Or if you declare a variable for editbox
m_Edit.GetWindowText(buff,256);
or if you use of WM_GETTEXT message ?

When I run above code I get null handle. so the code on next line is not execute.
I use same code in other function of same class for Setting string value to editbox,the code is executed in that function. So why i did not get the handle od edit box in above code.
Plz reply me.

Are you sure id of editbox is correct and what happens if you declare a variable for it did you can values of edit control.

Hi Hamid,
ID of Edit box is correct, because by using same ID i get the pointer for setting value to the window.
CEdit *pOpenEdit = (CEdit *) GetDlgItem(IDC_FOLDER_PATH);
if( NULL != pOpenEdit->GetSafeHwnd() )
{
if( strOpenPath != "" )
pOpenEdit->SetWindowText(strOpenPath);
}
This code is execute well but in following code i did not get the
handle.
CEdit *pOpenEdit = (CEdit *)GetDlgItem(IDC_FOLDER_PATH);
if( NULL != pOpenEdit->GetSafeHwnd() )
{
char buff[500];
pOpenEdit->GetWindowText(buff,256);
strOpenLocation = buff;
}
In this code I did not get handle so it is not entered in if block. Let me know what is wrong in this code.
Thanks in Advance

I have a question why you didnt declare a variable for edit control instead handle to it?
|

/*
I'm not sure what your having trouble with. However, I am confused what your using the handle for? Do you realize that your trying to use a pointer before you've even checked that it is valid?
*/
void CTest712Dlg::ShowEditText()
{
if (::IsWindow(m_hWnd)) {
CEdit* pOpenEdit=(CEdit*)GetDlgItem(IDC_FOLDER_PATH);
if (pOpenEdit) {
CString sText("");
pOpenEdit->GetWindowText(sText);
TRACE("%s\n",sText);
}
}
}
void CTest712Dlg::OnButton1()
{
// TODO: Add your control notification handler code here
ShowEditText();
}

Use ClassWizard (Ctrl+W) to associate a CEdit variable with the IDC_FOLDER_PATH control. Then use its GetWindowText() method.

CFtpConnection::CreateDirectory just takes a path string.
What exactly are you having trouble with?

how i can check whether the argument lpStr in FillStr function is initialized or not?
class myClass
{
public :
myClass()
{
}
~myClass()
{
}
LPSTR lpStr ;
};
int FillStr( <code>LPSTR lpStr</code> )
{
if( lpStr )
{
strcpy( lpStr , "myData" ) ;
return 1 ;
}
return 0 ;
}
void main()
{
myClass obj ;
if( FillStr( obj.lpStr ) )
{
printf( "%s" , obj.lpStr ) ;
}
}
Thanks & Regards

strcpy( lpStr , "myData" ) ;
This is a disaster waiting to happen based upon the way lpStr was passed in to your function. There is no indication to your method how big the buffer that lpstr points to so for all it knows, it might overwrite the buffer with the strcpy().
You never allocate memory for the buffer in your code. You should put that member pointer to the string in your initialization list for the class and set it to null or zero to ensure it has a known state before the class constructor is run.
If you know the buffer size, you can (reliably) check for the null terminator without worrying about overwriting the buffer. If the null terminator is at index zero, then it's empty. However, that does not necessarily mean that it wasn't initialized since "\0" is a valid string to initialize it with.
You might want to consider using an already existing string class written by someone who has thought all the possibilities out already.

strcmp return 0 if both strings are equal,try
if(strcmp(test,"Clerk")==0)
Thanks & Regards

strcpy(test,"Clerk");
The first line does not allocate enough space to contain the trailing \0, so that your next statement overruns the buffer. <understatement>This is not good.</understatement>
neodeaths wrote: if(test == "Clerk")
This is not the right way to compared strings that are accessed by a char *. Use strncmp or one of its cousins. The == only works on things like CString, which contain a comparison operator within their definition.
neodeaths wrote: if(strcmp(test,"Clerk"))
Read the documentation for the return type of the strcmp functions and that will tell you what is wrong with this statement.

Hi all,
Using code given on this link "http://www.codeproject.com/file/self_extractor.asp" i am preparing a exe file. But when i run this exe on another computer which is not having vc++ 6.0 installed in it. It gives an error of MFC42D.dll missing. What should i change its setting so that application should run properly....
Thanks in advance

The debug version needs not only MFC42D.dll, but also other debug versions of dlls, like MSVCRTD.DLL.
Try to build a release version instead, good luck.
