Try to scale the problem down to a much smaller one. Create just enough of an application that demonstrates the problem and go from there.

I have problem to read long strings from windows registry.
I have no problems with writing...
my code>
char m_sPiasPath[MAX_PATH];
char m_sIniPath[1024];
CRegKey cRegKey;
if(ERROR_SUCCESS!=cRegKey.Create(HKEY_CURRENT_USER,"Software\\psm",REG_NONE,REG_OPTION_NON_VOLATILE,
KEY_ALL_ACCESS,0,0 ))
{
MessageBox(0,"Can't create register key","PSM",MB_ICONWARNING);
}
else
{
if(ERROR_SUCCESS!=cRegKey.QueryValue(m_sPiasPath,"pias",&dwData))
{
// find pias.exe
CFileFind cFileFind;
if(cFileFind.FindFile("pias.exe"))
{
cFileFind.FindNextFile();
strcpy(m_sPiasPath,cFileFind.GetFilePath());
if(ERROR_SUCCESS!=RegSetValueEx((HKEY)cRegKey,"pias",0,REG_SZ,(BYTE*)((LPCTSTR)cFileFind.GetFilePath()),
cFileFind.GetFilePath().GetLength()));
}
else
MessageBox(0,"Can't find \"pias.exe\". Try run it manual.","PSM",MB_ICONWARNING);
}
// psm.ini
if(ERROR_SUCCESS!=cRegKey.QueryValue(m_sIniPath,"psm_p",&dwData))
{
if(::AfxMessageBox("Can't read path for \"psm.ini\" from windows registry.\nDo you want to select it?",
MB_ICONQUESTION|MB_YESNO)==IDYES)
{
CSelectPathDlg dlg;
dlg.DoModal();
strcpy(m_sIniPath,dlg.m_sFolder);
if(strlen(m_sIniPath))
{
if(ERROR_SUCCESS!=RegSetValueEx((HKEY)cRegKey,"psm_p",0,REG_SZ,(BYTE*)m_sIniPath,
strlen(m_sIniPath)))
{
::AfxMessageBox("Can't create registry key.",MB_ICONWARNING);
}
}
}
}
}
cRegKey.Close();
Thanks for help...

And what would that problem be? Have you single-stepped through the code, especially the call to QueryValue(), to see what is happening? Do the variables (e.g., m_sPiasPath, dwData, m_sIniPath) hold the expected values?

I get these all the time...
CONCEPT MALFUNCTION: IN/OUT Pointer means you must SET the value before calling function and it MIGHT be assigned a different value upon return.
BE aware of discussion like this in MSDN about the arguments to a function:
pdwCount
The size of the string data. Its value is initially set to the size of the szValue buffer.
You are lucky this works at all, because unless I missed something, you never set the value of dwData prior to either of your calls to QueryValue, and you SHOULD set it to something like sizeof(m_sPiasPath)
Try this instead:
dwData = sizeof(m_sPiasPath);<br />
if(ERROR_SUCCESS!=cRegKey.QueryValue(m_sPiasPath,"pias",&dwData))
and
dwData = sizeof(m_sIniPath);<br />
if(ERROR_SUCCESS!=cRegKey.QueryValue(m_sIniPath,"psm_p",&dwData))
These changes might cpmpletely fix your problem.

In addition to what Blake Miller said, you also need to use the pdwCount value returned, to determine the actual length of the string. The reason for this is that you can not depend on the string returned to be null terminated. Some of the query functions do not return a null terminated string and others that are supposed to do not do so on all Windows OSs. One way to work around this problem is to initialize the receive buffer (szValue) to all 0's and call the query funtion specifing a dwCount that is slightly smaller than the actual buffer size.

please help me..
I've develop something.
First I made a txt file that contains just some word "Hello, Bye, etc.." and then load it on the IE.
Second check the text on the IE, and then compare the text with some pattern like "Hello".
Third I add some html cord. The function of cord would change background color of the text "Hello" and hand cursor shape, if the pattern is same.
OK. Now I want to add some more function.
1. If I click the text that was already changed background color, and some more things,
('couse same with some pattern like "Hello")
then I want to make pop up my Dialog box(modal) on the IE. The box name is IDD_POPUP.
2. Next, the IDD_POPUP has a static text. I want to show the "Hello" on the static box of IDD_POPUP.
That's all.. plz help me~

Hi
How do we insert an image or an icon in a dialog?
/\|-||\/|/\|)
|
|
|
|
|
Just add a picture control to the dialog's template. Change it's type to either Icon or Bitmap. In the Image: combobox, select the id of the image (it must already exist) you want.
If you'll create a temporary dialog-based project that has an About box, you'll see how the icon on the About dialog template looks.

Click on the Picture Control icon in the Toolbox window and then click in the dialog's template where you want the control placed. It's just like adding any other control (e.g., button, listbox).

Exactly what do you mean "by code?" What I showed you will modify your project's .RC file, which is code your project needs in order to run.

i mean i nedd to create this image dynamically at run time so i need to write physically the code not using the rc interface

Check out:
CBitmapButton
CButton::SetIcon()
CButton::SetBitmap()
CStatic::SetIcon()
CStatic::SetBitmap()

hi again
Ok i need now to move the picture i have created in runtime how do i do that?

How about MoveWindow() or SetWindowPos()?

I can't use them with my image i have tried
how can i associate ID_image to be able to move it

But since you have not shown what code you tried with, how can I determine if you did it correctly or not?
Halawlaws wrote:

Based on what little I know of your problem, I'd start with GetDlgItem().

i cant use them
i dont have a class or a struct to call them all i have is the id of the image:ID_IMAGE

What does having a class or struct have to do with being able to use MoveWindow() or SetWindowPos()?

If u dont have a class and u use MoveWindow() the only thing that will move is the dialog u must specify that u want the image.
how do u do that?

Perhaps you are confused as to what MoveWindow() does. It changes the position and dimensions of the specified window, whether that window is a dialog, control, or a frame. If the window in which you are wanting to move has child windows (e.g., dialog having controls), all of them are moved too.

Hi guys,
Can anybody give me a explicit explanation about what is a HWND(handle to a window) , what does it differ from a CWnd object ?? Please provide examples if you can.
I've searched in MSDN but could not get enough information
Regards ,
Nick

I think it's like this: An HWND is a number (handle) to a window (dialog, edit box, etc) that is used by the Windows operating system to refer to the window specifically. CWnd is just an MFC class that encapsulates a registered window class and its handle. You could just as easily make up a class called CMyWindow and in the constructor have it call the Windows API to create a window of the type you want (button, for instance) in your class's constructor, then have the HWND be a property of your class. CWnd is just an encapsulating class, as is CListBox, CComboBox, etc.
